Researchers are investigating both failure may be caused by an abnormal biochemical process or a loss most of their neurons. Examples the abnormal and normal changes that occur over time and their of connections between neurons. Dozens of plays a role in sensory processes the effects of age on brain function are subtle and very selective.

Another points to genetic mutations cortex, which processes visual memories of recent events. The connectivity may start to forget names, phone numbers, or where you parked your mune system gone awry, and the accumulation of damage caused by between neurons changes with car, or you might respond more slowly to con icting information. The senile dementias include Alzheimers Aging neurons and cerebrovascular diseases and affect about 1 percent of people the brain reaches its maximum weight near age 20; subtle younger than age 65, with the incidence possibly increasing to nearly changes in the chemistry and structure of the brain begin at 50 percent in those older than 85. During a lifetime, the brain is at risk for functioning seems relatively unaffected by age. Many people do well losing some of its neurons, but normal aging does not result in throughout life and continue to do well even when old, at least until widespread neuron loss as occurs in Alzheimers disease or after shortly before death. Brain tissue can respond to damage or loss of neurons often make up for de cits in performance. The oldest human, Jeanne by expanding dendrites and ne-tuning connections between Calment, kept her wits throughout her 122-year life span. A damaged brain neuron can readjust to damage only the belief that pronounced and progressive mental decline is if its cell body remains intact. If it does, regrowth can occur in the aging brain is only as resilient as its circuitry. Physical exercise, however, inevitable was and still is popular for several reasons. When neurons are destroyed, nearby surviv debate whether this circuitry is changed only by neuron atrophy improved blood circulation in the brain. In 1900, when average ing neurons can compensate, in part, by growing new dendrites and or whether some neuron loss over time also is inevitable. Physical exercise also can improve neuronal functions event, when the circuitry begins to break down, remaining neurons Although much has been learned about the aging brain, many of the population, were older than age 65 and typically were ill. For instance, does the production of proteins 2003, when life expectancy was more than 77 years, nearly 36 million can be recruited in older people to accomplish performance levels decline with age in all brain neurons In a given neuron, does people, or more than 12 percent of the population, were older than Intellectual capacity similar to those of younger adults.

But the response is more slug and to ask questions about what actually happens in its aging cells. This research is supported by animal studies in which scientists gish and not as large.

These latter brain sys tems are important in inhibiting behavior and in decision-making. The process of becoming addicted is in uenced by many fac tors that scientists are only beginning to understand. Genetic susceptibility and environmental Addiction abuse drugs on a regular basis. Recent estimates show that the abuse factors, such as stress, also alter the way that people respond to of drugs, including alcohol and nicotine, costs the nation more drugs. The characteristics of the drugs themselves, such as how Alzheimers Disease than $276 billion each year.

These illustrations show what areas are most likely part of the re Neurological Trauma Neuroscientists have learned a great deal about how drugs of and addiction is estimated at $185 billion. A central group of structures is common to the abuse affect neurons to exert their in uence. Abused drugs alter the Genetic and environmental factors contribute to alcoholism, actions of all drugs. These structures include a collection of dopamine-containing Pain ways neurotransmitters carry their messages from neuron to neuron. These neurons are connected to Parkinsons Disease Some drugs mimic neurotransmitters, whereas others block them. Cocaine Still others alter the way neurotransmitters are released or inacti Alcohol activates the endogenous opioid system so that sus exerts its effects mainly through this system. Ultimately, in all cases, the brain reward system is activated ceptible individuals may feel an opioidlike euphoria from their own other brain regions, including the amygdala, that normally use opioid peptides. Based on animal research showing Opioids are naturally occurring brain chemicals that induce the same actions as Seizures and Epilepsy among neurons in this circuit. They generally provide users with lower overall nicotine levels than A standard treatment for opiate addiction involves methadone, anxiety, tension, and inhibitions. In low doses, it may act as a Physical exhaustion also can enhance some toxicities and problems. In both Marijuana this drug distorts perception and alters the sense and its deadly contents. Methadone helps opiate addicts rehabilitate cases, it signi cantly alters mood and behavior.

Another medication to treat heroin addiction, buprenorphine, Club drugs Ecstasy, herbal ecstasy, Rohypnol ("roo es"), information. These drugs are rumored to increase stamina and to pro the development of medications that target the endogenous can patients in the United States. Recent research, however, is uncovering the serious treating a number of different brain disorders, including addiction, amphetamines. Nicotine In 2003, more than 70 million people smoked, at more than alcohol, cocaine, heroin, the United States. It enters the brain in seconds, producing a rush homicide, suicide, car accidents, synthetic psychoactive drug with hallucinogenic and amphetamine substances. The key biochemical factor that underlies the reinforcing links chronic ecstasy use to long-term changes in those parts of the preventable cause of death in the United States. Smoking is respon effects of psychostimulant drugs is their ability to greatly elevate brain critical to thought, memory, and pleasure. The direct and indirect costs of nucleus accumbens, and repeated use of these drugs progressively vous system depressants. Because they are often colorless, tasteless, smoking are estimated at more than $138 billion per year. Opiates Humans have used opiate drugs, such as morphine, increases their ability to activate brain dopamine systems. This is and odorless, they can be added easily to beverages and ingested Nicotine, the addicting substance in tobacco, acts through for thousands of years. Monkeys and rats readily self-administer heroin thought to result in a progressively increasing motivation to take unknowingly. These drugs have emerged as the so-called date the well-known cholinergic nicotinic receptor. This drug can act or morphine and, like humans, will become tolerant and physically de the drugs, eventually leading to addiction. When mixed with alcohol, Rohypnol can incapacitate as both a stimulant and a sedative. Withdrawal symptoms range from mild, Cocaine users often go on binges, consuming a large amount victims and prevent them from resisting sexual assault. Rohypnol glands, and the resulting discharge of epinephrine causes a "kick": a ulike discomfort to severe muscle pain, stomach cramps, diarrhea, and of the drug in just a few days.

Mascot runs around the family tickling them erectile dysfunction herbal medications buy levitra plus cheap online, making faces, anything to get their attention. Trainer Note: Ensure that all participants have their Maltreatment Index for the next section. We will begin by discussing how the parent/caregiver inappropriately using drugs or alcohol may affect the child. The first subsection of this maltreatment is the caregiver inappropriately using drugs or alcohol. One way this can be established is through "A test administered at birth which indicates that the childs blood, urine, or meconium contained any amount of drugs, alcohol or a controlled substance or metabolites of such substances, the presence of which was not the result of medical treatment administered to the mother or the newborn infant. Because of this, the positive test alone, is evidence to support the statutory definition of "Harm. If you look at these typical newborn behaviors in the context of a non-substance-abusing parent, they can be challenging. When you think of them in the context of a substance-abusing parent, whose behaviors, thoughts and actions are controlled by the substance he/she is abusing, you can have a dangerous situation. As we discussed previously in this module, this combination of factors also leads to most of our co-sleeping deaths. Trainer Notes: Again, stress the importance of having a discussion with about co-all families we work with about co-sleeping, and provide additional resources on safe sleeping environments. The second way to establish this maltreatment is through "Evidence of extensive, abusive, and chronic use of drugs or alcohol by the caregiver(s) when the child is demonstrably affected by such usage. Please select the one(s) you would like them to review for the class and provide them. Breast Feeding Death Stephanie Greene, 39, faces 20 years to life in prison when she is sentences for killing her 6-week-old daughter with what prosecutors say was an overdose of morphine delivered through her breast milk. A prosecutor said Stephanie Greene, 39, was a nurse and knew the dangers of taking painkillers while pregnant and breast feeding, instead choosing to conceal her pregnancy from doctors so she could keep getting her prescriptions. The 20-year sentence was the minimum after a Spartanburg County jury found Greene guilty of homicide by child abuse Friday. She said nothing in court and quietly shuffled out of the courtroom, her hands and feet shackled, after she was sentenced. Forty-six days later, Greene called 911 to report her baby was unconscious in her bed. A review of her medical records showed Greene carefully hid her pregnancy from her primary doctor. After a home pregnancy test showed she was pregnant, she told her doctor she needed to go to a gynecologist for a birth control. Trainer Note: After each section, have a brief group discussion of how we may see this in the families we work with. For many years, experts have tried to explain the relationship between substance abuse and family violence, but research has demonstrated that substance abuse by itself does not cause violence. Studies focused on alcohol agree that alcohol facilitates or triggers, rather than causes, physical violence. Furthermore, the relation between alcohol and violence is most affected by multiple factors, such as personality, provocation and threat, as well as learned alcohol expectancies, situational factors and biochemical factors. It also helps participants understand the survivors actions to protect themselves and their children. Discuss types of family responses when domestic violence is occurring as part of their family dynamics. List strategies survivors of domestic violence may use to protect themselves and their children. Explain the role of injunctions and interventions for the victim, the children and the batterer. Discuss the roles of domestic violence advocates with child welfare professionals. Define the maltreatment Family Violence Threatens Child and how it applies to families where there is domestic violence. Given a scenario and using the Maltreatment Index, evaluate if it represents domestic violence, and explain your rationale. Trainer Note: Here are a list of You Tube videos that you can use during the unit. Write participant responses on a flipchart page or white-board without judging their responses as correct or incorrect. Later, if there is a response on the flipchart that is an example of what you are discussing in the definitions or dynamics, you can point it out then. Also, if you have information later that is in opposition to a response, you can note it then. It is important to let participants know that if they have had experience with domestic violence (either as a victim themselves or a friend or family member that has been victimized), they should not feel that they must disclose. However, if they do, recognize that this is not a confidential group, so although folks may say they will not share their colleagues story, there is nothing stopping them. This way, folks can think through and decide if they are comfortable with sharing, knowing the potential risk of such. There may also be content that triggers difficult emotions for participants and/or memories of traumatic events in their lives. Let participants know that they should feel free to take care of themselves and if they need to leave the room at any point to do so. Can you tell me about some people in relationships or families who have been impacted by domestic violence Use their examples to discuss the definitions of domestic violence described later on in the unit. Trainer Note: Do some research prior for any recent stories in the news regarding domestic violence. There are several different definitions; lets see if we can identify the similarities and the differences. Domestic violence is not a disagreement, a marital spat, or an anger management problem. Domestic violence is abusive, disrespectful, and hurtful behaviors that one intimate partner chooses to use against the other partner. The danger threat of "parent/legal guardian/caregiver is violent, impulsive, or acting dangerously in ways that seriously harmed the child or will likely seriously harm the child" includes an operational definition of domestic violence as follows, "When violence includes the perpetrators dynamics of power and control it is considered domestic violence. Some of these are criminal, some are not; some of these are physically damaging, some are not. It is important to note that not all domestic violence perpetrators use all of the tactics. One domestic violence perpetrators pattern may include one event of physical force. Another domestic violence perpetrator may repeatedly use physical violence against the adult victim and/or children. Not all assaults are part of an ongoing pattern of coercive behaviors that result in gaining power and control over a partner. A domestic violence victim may use physical force (in self-defense or in retaliation) without engaging in a pattern of assaultive and controlling behavior against the domestic violence perpetrator. For the purpose of this training, we refer to domestic violence pertains to the intimate partners of spousal, live-in partners and dating relationships; however, as a child welfare professional, you will also see violence in familial relationships, which is encompassed in the maltreatment definition of Family Violence Threatens Child. I use the term "intimate partner violence" to stress that while a majority of abusers are male and the majority of victims are female, this is not always the case. According to the National Coalition Against Domestic violence, adult domestic violence victims come from all groups: all ages, races, religious affiliations, occupations, educational levels, and personality types. Rural and urban women of all religious, ethnic, socio economic and educational backgrounds, and of varying ages, physical abilities and lifestyles can be affected by domestic violence. This is not to say that there are not female perpetrators but rather to show that often times when women are arrested or labeled a perpetrator in some other way, it is the result of self-defense and/or retaliatory violence. Regardless of who the victim is, he or she may tend to minimize and deny the violence in order to protect their children and himself or herself from the batterer. National Institute of Justice and the Centers of Disease Control and Prevention, "Extent, Nature and Consequences of Intimate Partner Violence: Findings from the National Violence Against Women Survey," (2000). There are specific cultural groups whose particular vulnerabilities may put the members of that population at greater risk of experiencing violence in their relationships. Some obstacles may include a distrustful attitude toward the legal system, language and cultural barriers (that may at the least be unknown and at the worst hostile), and fear of deportation. Individuals with Physical, Psychiatric and Cognitive Disabilities People with disabilities experience sexual and domestic violence at higher rates than the mainstream population. They may also experience maltreatment from their caretakers, including personal assistants, paid staff, family members and parents. Older Battered Women Domestic violence in later life is a subset of the larger issue of elder abuse. Older women are a nearly invisible, yet a tragically sizable population who are uniquely vulnerable to domestic violence. Unlike domestic violence, elder abuse may not be perpetrated by an intimate partner or include power and control dynamics. Battered Women Living in Rural Communities Survivors in rural areas often face a lack of resources, isolation, small-town familiarity among neighbors, few (if any) support agencies, and poor or little transportation and communication systems in addition to the other barriers to safety that may be compounded by the rural lifestyle. The patriarchal "good old boys" network, fundamentalist religious teachings, deep-rooted cultural traditions and commonly accepted sexual stereotyping can form a chorus of accusations that the battered rural woman is unfaithful in her role as a woman, wife and mother. The act of leaving the home place, land and animals that could depend on her may be emotionally wrenching leaving the battered rural woman surrounded by walls of guilt and self-abasement. Same-sex battering can happen in any same sex relationship regardless of culture, race, occupation, income level and degree of physical or cognitive ability. Tell participants they will be working closely with this handout in their work and discuss how this assessment tool can help them identify and describe a batterers pattern of coercive control. The wheel is another way of graphically representing the dynamics in a family that has inter partner violence issues. These wheel sections represent many of the tactics batterers use to gain and maintain power and control in the relationship. Here are a few of the many facts that clearly underline the fact that domestic violence can lead to child abuse: the U. Advisory Board on Child Abuse suggests that family violence may be the single major precursor to child abuse and neglect fatalities in the United States. Battering is a choice, and many men who witnessed abuse as a child do not abuse their partners. If he says he will kill himself, understand that this likely means he will kill the partner, as well. If the abuser owns weapons or has access to weapons, and has used them or threatened to use them in the past, there is a potential for a lethal assault. We will look at a lethality assessment in your next lab and discuss ways to interview with this in mind.

In total, 109 different laboratories participated, mainly from Germany, but also from the Netherlands, Austria, Portugal and Sweden. Inter-laboratory tests increase the quality of the analysis in the participating laboratories. This was already evident from the first few tests for identification of indoor fungi. The statistical evaluation showed that laboratories which took part more than once in the tests were more successful than new com ers Samson 305 the inter laboratory test are planned every 6 months and the cultures used as ref erences will be deposited at and available from the Centraalbureau voor Schimmelcultures in Utrecht, the Netherlands ( Besides the reference cultures also dust and air samples have been distributed among the participating laboratories. These analysis have been appreciated by the participating laboratories to test their skills. It is planned to expand the inter-labo ratory tests to other countries and contacts to national reference laboratories are sought. The standardization of meth ods and quality assurances for laboratories active in microbial surveys and the international inter laboratory tests are primary aims of the commission. Rantio-Lehtimaki 1University of Turku, Department of Biology, Section of Ecology, Turku, Finland. It is typically found on gypsum board, which consists of a gypsum layer between cellulose cardboard liners. Stachybotrys chartarum is known to produce mycotoxins and it has been linked with serious diseases, such as stachybotryotoxicosis in both animals and man, and idio pathic pulmonary haemosiderosis in infants. Due to the increased health risk, the detection and identification of Stachybotrys has been considered important for instance in governmental remediation instructions (Morey, 2001). Furthermore, it is often overgrown by other molds such as Penicillia, Trichoderma, Mucor and Rhizopus. Cellulolytic characteristic of Stachybotrys is often emphasised in a search for good detection media. Clay minerals, especially montmorillonite have been shown to accelerate growth of Stachybotrys (Jong, Davis 1976). In a previous study on the fungal solu bilisation of calcareous building materials, 0. The Finnish strains were isolated from moistened building materials and from indoor and outdoor air. Gypsum suspension was prepared in a small volume of sterile deionized water and added to the melt (57 C) medium after steam-sterilisa tion. Media containing cellulose or starch, including sterile filter paper on medium, medium containing wallpaper paste (Hoekstra, Samson, Summerbell, 2000), oat meal, and corn meal agar (Domsch, Gams, Anderson, 1993), have been recommended for the detection of this cellulolytic fungus. Andersen & Nissen (2000) found oat, corn and rice meal agar unsuitable for the detection of Stachybotrys. Even though the diameter of the colonies increased, colony density remained so low that it could be overgrown by competing fungi and/or overlooked by the inspector. Media with vegetable-based carbon sources, such as potato-sucrose agar and V8 juice agar, yielded denser colonies and were recommended in this study. However, in these two studies the ratio between growth rates on gypsum amended and gypsum-free agars varied from 0. However, its applicability to air and material samples with varying spore types should be investigated further. Nevalainen 1National Public Health Institute, Department of Environmental Health, P. Although the pH ranges were strain specific characteristics, they depended also on the composition of the medium. These results show clearly that culturing streptomycete spores at different pHs induced significant differences in their ability to evoke cytotoxicity in mammalian macrophages. Moreover, in moisture damaged buildings, these bacteria are also able to produce toxins (Andersson et al. In vitro, the spores of strep tomycetes evoke cytotoxicity and induce the production of inflammatory media tors in immunological cells (Hirvonen et al. The nutrient composition and the pH of the environment can greatly affect the growth, sporulation, morphology, and production of secondary metabolites by streptomycetes. Streptomycetes can degrade complex polysaccharides (starch, pectin chitin), proteins (keratin, elastine) and aromatic compounds. If the amount of nutrients essential for the growth is limited, the pH of the medium becomes an important factor controlling growth. Generally, both acidophilic and alcalophilic streptomycetes have been found, but most species prefer a neutral to alkaline envi ronment with the pH optimum lying between 6. The nutrient composition and the pH of the medium can influence the metabolism of streptomycetes, their growth and their biosynthesis of secondary metabolites. In this study, the interaction of the nutrients and pH on the growth, sporulation and cytotoxicity of streptomycetes isolated from moldy indoor environments was ana lyzed. The strains were culti vated on seven different media (Table 1) solidified with 1. These media favored the growth of streptomycetes in a cultivation experiment carried out pre viously (Suutari et al. The data were analyzed using one-way analysis of variance and Duncans Multiple Range test, Wilcoxon Signed Rank Test and Wilcoxon Rank Sum Test (p<0. Under identical circumstances, pH modified the growth and the sporulation, but separate strains reacted differently. In general, the growth pH ranges for the streptomycete strains studied were broad, with pH min imum ranging between 4. Although the pH ranges were a strain specific character istic, they depended also on the medium composition. With respect to the growth of the mycelium, the pH range was broadest on media 2, 3, 5 and 7; i. Changing the mineral solution of the glycerol-arginine agar to yeast extract increased the growth and broadened the pH range of the growth to the acidic direction. Some of the strains sporulated less under acidic conditions, which may be due to the growing conditions or due to genetic reasons (Hopwood 1988; Chater 1989). Moreover, also the pH of the growth medium influenced the cytotoxicity of the spores of the same strain. This may be an important aspect in understanding the causal relationships between microbes in moldy buildings and their effects on health. Our results on streptomycetes isolated from indoor environments demon strate that their pH tolerance extends over a wide range and depends on the nutri tional status of the environment. This study was supported by the Academy of Finland and the Finnish Work Environment Fund. Hirvonen 1National Public Health Institute, Department of Environmental Health, P. It has been shown that the presence of Streptomyces californicus and Stachybotrys chartarum indicates moisture and mold damages in a building. In this study we identified interactions between the bacteria and fungi on physiological state and biomass of the microbes. Also the total microbial biomass of this microbe is greater when cultured together with S. These results indicate that co-cultivation affects the physiological state and the bio mass of the microbes. Earlier we have used fatty acid methyl esters to study the effects of plasterboard composition on Streptomyces californicus growth (Murtoniemi et al. On the other hand, differences in fatty acid composition can reveal changes in physiological state of pure culture microbes. The gram-positive bacterial strain Streptomyces californicus and the fungal strain Stachybotrys chartarum were selected in the study based on their characteristic occur rence in water damaged buildings (Samson et al. In this study we investigated more detailed interactions between these two microbes. The aim of the present study was to identify differences in microbial biomass and physiologi cal state when the microbes are cultured separately and together on the same cul ture medium. The lyophilized samples were saponified, methylated and extracted as methyl esters. The present data also support the findings showing that the fatty acids 16:0, 18:0 and 18:2 dominate the profile of this fungi. These microbial interactions may affect the bioactivity of these microbes leading to currently unknown responses in mammalian cells. Thus, the microbial interactions need to be further studied and carefully considered when evaluating the possible health effects associated with exposure in moldy houses. Culture methods gave only limited information about the mold species present in building dust and the quantities of colony forming Haugland et al. Calculation methods for enumerating target organisms in the samples have been extensively described (Brinkman et al. Statistical analyses of both total and categorized populations were carried out using the 2-tailed Wilcoxon-Mann-Whitney U-test. Aureobasidium pullulans, Aspergillus penicilliodes, Cladosporium cla dosporioides, Epicococcum nigrum and Eurotium spp. Species occurring in the highest abundance may not be the best indicators of such buildings. Without the presence of fruiting bodies (basidiomata), positive identification of wood decay fungi based on the mor phological characteristics of the vegetative structures is impractical and unre liable. Three sets of primer pairs and probes were selected and evaluated for specificity and sensitivity of detection. In addition, samples collected from different residential build ings tested positive only if they were infested and decayed by M. Hosts include, Pinus, Pseudotsuga, Quercus, Sequoia, Sequoniadendron, Taxodium, Tsuga, Robinia, and Magnolia (Farr et al. Merulioporia incrassata often occurs in new or remodeled hous es and can cause extensive damage within two to three years. Common water or moisture sources in buildings, which may lead to the develop ment of this fungus, include water leaks and wood in close contact with soil infest ed by the fungus. One of the reasons for making this fungus very destructive is its ability to transport water for 50 to more than100 cm through mycelia fans, and mycelial strands or rhizomorphs, allowing it to transport water from the soil or other water sources to the wood (Verall 1968). Merulioporia incrassata may produce a dry rot form of attack as do Serpula lacrymans and several wood decay fungi. However without the presence of basidiomata, iden tification of this fungus, based on morphological characteristics, is difficult and impractical. It is therefore necessary to develop a reliable and accurate method to identify M. The objective of this study is to develop species-specific primer pairs and probes for rapid and accurate identification of M. Mycelial samples from 5 to 10-day-old colonies were harvested with a surgical scalpel from the surface of pure cultures. The concentration and purification protocols were performed following manufacturers specifications. Briefly, a portion of each wood sample or various pieces of wood were selected and added to a 15 mL centrifuge tube containing 10 mL of 0. With the use of Applied Biosystems reagents, the amplification conditions were as follows: 1X TaqMan master mix (with AmpErase Uracyl N-Glycosylase); 0. Four high variable regions were identified for the selection of primers and probes using Primer Express Software (Applied Biosystems).

The route of entry for infection for this organism is through the lungs, with possible systemic spread via the circulatory system to the brain and meninges. There are four cryptococcal serogroups associated with disease in humans and animals, distinguished by capsular polysaccharide antigens. Cryptococci of serogroups A and D have a world-wide distribution and are partic ularly associated with soil and weathered bird droppings, although the birds them selves are not affected by the organism (Kwon-Chung 1990, 1992; Hubalek 1975). However, begin ning in 1999, increasing numbers of cases of human and animal disease associat ed with C. Since January 2003 there has been a sudden increase in the number of cases of cryptococcosis reported in companion animals, with some 40 new cases this year in cats, dogs, ferrets and one bird. Swabs were dipped into the media to wet the swab which was then rubbed into limb holes, natural cracks in bark, or holes in bark made by birds or animals. The swab was then inserted into the transport media and placed in a cooler for transport to the laboratory. In homes, the swabs were also used to collect material from house plants, window ledges, or areas where afflicted pets spent time. In the laboratory, the swabs were streaked onto a differential agar medium (Niger seed agar).

The mode of mode of delivery, the child must keep his or her mouth closed oxygen delivery used is based on the concentration or and breathe through the nose. To ensure patient safety, meas ure and monitor the concentration of inspired oxygen Medications carefully and document response during oxygen therapy. Routes of administration mm Hg) and arterial hemoglobin saturation (SaO2) are oral, inhaled, intravenous, and injectable (subcutane (more than 93%). Inhaled medications are used most an artificial airway such as an endotracheal tube or a tra often to increase respiratory tract absorption and to cheostomy tube, the gas must be artificially heated and decrease systemic absorption. Other groups of medications often used in conjunction with these include, receiving oxygen therapy through an artificial airway for but are not limited to , antibiotics, antivirals, mucolytics more than 1 to 2 hours should receive warmed, humidified and expectorants, decongestants, antihistamines, and diu oxygen. The pharmaceutical agents used for particular respiratory disorders are addressed in the appropriate the use of oxygen therapy in the home is becoming sections. Bronchodilators, corticosteroids, and mast cell stabilizer Aerosol Therapy medications are delivered by inhalers or nebulizers. How ever, bronchodilators and corticosteroids are also available Question: Jose uses a nebulizer at home. What sup by inhalation is effective, because the medication reaches portive rationale can you offer for why this method of the small airways and works directly on the lungs. Use of a spacer allows time for the propellant to remain suspended and achieve smaller particle size. Using spacers with mouthpieces requires coor dination of breathing and drug dispersal, so spacers with masks may facilitate dosage in younger children. The handheld nebulizer has the advantages A third type of device for administering inhaled medi of being able to aerosolize almost any drug available in liq cations is breath-activated inhalers. With these devices, uid form, allowing modification of dose volume and con medication is delivered as the patient takes a breath. Nebulizers are effective for most children sounds and respiratory effort before and after the treat younger than 5 years of age and older children who have ment for effectiveness. When the child is getting the treatment, he or she may like to have teddy or dolly wear a Be sure to have the child rinse out the mouth or wash the mask and get a treatment, too. Simply breathing in and out deeply will allow the medication to work directly on the lung tissue. Ventila tion and gas exchange are altered, producing a favorable environment for infection. Do not burn incense, candles, nasal cannula under the nose and over the ears, or fires in the home. Keep the oxygen tank more with the portion with the holes positioned under than 5 feet away from the heater or any other heat the nose, and how to attach the cannula to the sources. Avoid places that hypoallergenic tape or skin protectant on the areas allow smoking. Several methods are available to provide artificial venti Suctioning the trachea and nasopharyngeal airway is a lation. A bag-and-mask unit, or Ambu bag, is used to man method to enhance airway clearance by removing secre ually ventilate a child who has not been intubated (had an tions that cannot be removed by the childs spontaneous endotracheal tube placed). Suctioning may also be used to obtain secretions tion is best provided with a self-inflating bag and a mask for diagnostic purposes (see for Procedures: that fits properly over the childs nose and mouth. To provide an open airway, extend the infants or Traditionally, chest physiotherapy (also called postural childs neck slightly in the sniffing position and lift the drainage and percussion) has been the primary intervention jaw. The jaw thrust maneuver is used in the for pulmonary conditions with hypersecretion or retained pediatric trauma victim with possible spinal injury or in bronchial secretions. However, more therapy options for infants for whom overextending the neck can occlude the airway clearance exist now than were available in the airway. Ongoing research to match the most effective over the nose and mouth to create a seal. With your therapy with the individual will improve quality of life in dominant hand, compress the bag rhythmically and in this rapidly expanding area. Ensure that the bag Determining the appropriateness of these newer inter is connected to an oxygen source, with oxygen delivered ventions for a particular patient requires assessing the at a flow rate of 10 to 15 L/minute. Endotracheal intubation is the insertion of an should be performed 30 minutes before mealtimes, as a artificial airway (an endotracheal tube) through either the safety measure to avoid vomiting and aspiration, and to nose (nasotracheal) or the mouth (orotracheal) into the promote comfort. Another less invasive device for me chanical ventilation (used most commonly in the operat ing room) is the laryngeal mask airway. Mechanical ventilation replaces the work of breathing and involves inflating the lungs with compressed gas, applied by either positive or negative pressure. Positive pressure ventilators are more commonly used than nega tive-pressure machines. They work by creating pressure at the airway opening that is greater than the intra-alveo lar pressure, thus forcing pressurized gas into the lungs. This flow of compressed gas improves gas exchange and inflation of poorly ventilated portions of the lungs. Nega tive-pressure machines are more cumbersome and are primarily used for long-term ventilation in persons with respiratory failure caused by neuromuscular diseases. Done for 5 to 15 breaths, followed by two to three huffs through flutter until lungs are clear, or for 20 minutes. Another mode of providing mechanical ventilation is called high frequency ventilation. This machine works by delivering oxygen under high pressures at a rapidly cycling rate. Closely monitor the respiratory and cardiovascular sta tus of the child receiving mechanical ventilation. Perform suctioning based on the presence of adventitious breath sounds, increased re spiratory effort or distress, or both. Provide oral care and ensure the intubation tube is not causing skin irritation around the mouth or nares. Ensure the ventilator alarms are on and set within acceptable pa rameters to provide early notification of distress. In some clinical condi tions such as laryngotracheomalacia, subglottic stenosis, or vocal cord paralysis, the tracheostomy may be long term, until the condition is outgrown or corrected. More over, with some cases, such as in chronic respiratory failure with long-term mechanical ventilation, the tracheostomy may be permanent. Tracheostomy tubes are made of Silastic, silicone, or metal and are available in various sizes and lengths. Single-cannula tracheostomy tubes are most commonly used in pediatric patients, because they have a smaller inner diameter and are usually made of Silastic, which conforms better than other materials to the shape of the trachea. The inner cannula is removed for cleaning, while the outer cannula is left in place. The tube has not yet been Additionally, some tracheostomy tubes have external secured in place. Most pediatric tubes do not have an external cuff because of the childs small airway diameter and the increased risk of trauma to the airway caused by the cuff. Because cuffless single-cannula tracheostomy tubes are the rationale for the use of mechanical ventilation. As used in most children, explanation of the nursing care appropriate, provide medications to help the child remain focuses on these. Preoperatively, explain to the child and parents why the A tracheostomy consists of the surgical placement of an tracheostomy tube is needed, what the basic anatomy artificial airway directly into the trachea below the lar and physiology of the airway are, how breathing will be ynx. Many conditions that can cause upper airway different, what to expect postoperatively, and how the obstruction, respiratory failure, or prolonged intubation child will look when he or she returns from surgery. If in children may have to be managed by placing a trache possible, allow the family to see a tracheostomy tube ostomy tube. Emergencies such as epiglottis or foreign andsuppliestohelpdecreaseanxietyaboutwhatto expect. Because infants and children are at Does infant position affect outcomes of newborn greater risk for tracheostomy obstruction related to the infants receiving mechanical ventilation All children with a tracheostomy should have an extra tracheos assessing the position of neonates receiving mechanical tomy tube of the same size available at the bedside in case the tube in place is ventilation have not substantiated that any particular dislodged or becomes obstructed and cannot be cleared. The prone position has been found to slightly improve ox ygenation in neonates receiving mechanical ventilation; Respiratory assessments include vital signs and exami however, more research is needed to determine the vari nation of the childs color, respiratory rate and effort, ous risks and benefits associated with different laying breath sounds, and type and amount of secretions. For positions for this population of ventilated patients (Bala the first 5 to 6 days, until the tracheocutaneous tract is guer, Escribano, & Roque, 2003). The sutures can be used to Chapter 16 n n the Child With Altered Respiratory Status 671 keep the stoma open in the event of an accidental decan nulation. The airway must remain patent to prevent obstruc tion and possible complications. The child may require frequent suctioning for several hours immediately after the procedure, because excessive and sometimes bloody secretions are common. Provide suctioning on an as needed basis thereafter to prevent occlusion of the tra cheostomy tube by secretions and mucous plugs. It is also helpful to ensure that visiting nursing is provided after discharge to assist the family with routine care. Studies do not demonstrate the efficacy of normal saline in thinning mucus Nursing Plan of Care for secretions. Studies have shown that instilling saline before the Child With Altered suctioning has an adverse effect on oxygen saturation, which may last up to 5 minutes. Also, instilling saline during Respiratory Status suctioning dislodges bacteria into the lower airway. Question: One nursing diagnosis for Jose is: Inef the functions of warming, filtering, and humidifying fective breathing pattern related to respiratory disease inspired air that the upper respiratory tract normally per process. Based on the information in the case study, what is forms are bypassed in a child with a tracheostomy. Health promotion and disease prevention activities are Nursing care is directed toward maintaining appropriate essential for infants, children, and adolescents with acute humidification via a mist collar.
