Aciclovir

Assad Aghahoseini FRCS

Blood flow through the tissue increases and the increased venous return to the heart raises the cardiac output hiv rates of infection in us buy aciclovir 400 mg without a prescription. The coronary circulation is an excellent example of auto regulation antiviral eye drops 400mg aciclovir overnight delivery, whereby the volume of blood flowing through the heart is adapted to the need of cardiac muscle fibers hiv infection rates us cities purchase aciclovir 400 mg otc. When the stroke volume of the heart is increased antiviral untuk chicken pox buy aciclovir 200mg with visa, more blood is immediately pushed into coronary arteries at the same time that the blood is ejected into the aorta hiv infection menstrual cycle generic 400 mg aciclovir free shipping. During ventricular systole anti virus ware cheap 200 mg aciclovir with mastercard, the contracting ventricles compress the small coronary vessels. At rest, the coronary circulation 197 receives about 5% of the total cardiac output; it increases four to five times during strenuous exercise. Regulation of arterial blood flow In the elastic arterial vessels the blood inflow is intermittent, that is, only during the systole of the cardiac cycle, whereas the outflow from the arterioles to the capillaries is continuous. Then as the elastic arterial wall distends, the ventricles begin to relax (diastole) & the semi-lunar valves close due to pressure gradient. During diastole the aortic /pulmonary pressure continues to fall and as the elastic aorta recoils, blood is pushed to the periphery. Higher brain centers, such as hypothalamus and cerebral cortex, coordinate the cardiovascular responses depending on the stimulus. Same neural & humoral factors are involved in short-term blood pressure regulation (minutes to hours). Short term (within Seconds) adjustments are accomplished by alterations in cardiac output, total peripheral resistance, mediated by means of autonomic nervous system on the heart, Veins and arterioles. Long-term (Regulating minutes to days) control system involves adjustments of blood volume by restoring normal salt and water balance, through mechanisms that regulate urine output & thirst. These 200 receptors are fine nerve endings present in the arterial wall that are stimulated by tension/stretch of the arterial wall evolved by blood pressure. Vasomotor center: its location, input from the higher centers and output to the effector. The cardiac inhibitory center lies in medulla and includes the dorsal nucleus of vagus. It slows the heart rate and decreases the contractility of the heart through the impulses sent through the efferent fibers of the vagii. They are regulated by higher hypothalamus and cerebral cortical regions and in turn, the heart and blood vessels, are capable of some intricate auto regulation. Cardiovascular control areas receive information from many peripheral inputs, including arterial baroreceptors, mechanoreceptors in the heart and 202 lungs, arterial chemoreceptors (Carotid and aortic bodies), and input from skeletal muscles. The high-pressure baroreceptors are the most important source of peripheral input. The baroreceptor afferents also lead to suprapontine structures: the reticular formation, limbic system, and the fronto-orbital cortex. The carotid sinus and aortic arch baroreceptors increase the rate of firing in their afferent nerve. These efferent signals decrease heart rate, decrease stroke volume, and produce arteriolar and venous dilation, which in turn lead to decrease in cardiac output and decrease in total peripheral resistance, with a consequent decrease in blood pressure back towards normal. Conversely, when blood pressure falls below normal baroreceptor activity decreases, inducing the cardiovascular center to increase sympathetic cardiac and vasoconstrictor nerve activity, while the parasympathetic output is decreased. This efferent activity pattern leads to an increase in heart rate and cardiac output coupled with arteriolar and venous vasoconstriction. These changes result in an increase in both cardiac output and total peripheral resistance, producing an elevation in blood pressure back towards normal. These include: sympathetic cholinergic vasodilatation in 203 skeletal muscle which promote immediate increase in blood flow to the muscles to be used, sympathetic vasoconstriction else where which increase blood pressure, increase heart rate and contractility, increased catecholamines production, increased respiratory rate, piloerection (in animals). The heart slows (bradycardia), blood pressure falls, and a state similar to fainting occurs. There appears to be a very strong inhibition of the sympathetic cardiovascular centers. After stimulating of the amygdala, both pressure & depresser responses have been observed both the hypothalamus and amygdale are capable of strongly influencing all circulatory reflex responses. Higher Centers: the fronto-orbital cortex modulates hypothalamus integration of cardiovascular activity. The most important is to help the hypothalamus resetting the responses to the baroreceptor reflexes. This resetting is important for the maintenance of an adequate high blood pressure during exercise or response to danger. The role of the cortex in these control mechanism is not still clear other than that if it is removed there is impairment of cardiovascular responses. In some it may cause fainting probably due to powerful stimulation, through the hypothalamus, of the medullary cardioinhibitory and vasodilator centers. Some reflexes and 204 responses influence blood pressure though they primarily are concerned with the regulation of other functions. The chemorecepor function is to reflexly increase respiration to bring more oxygen or to blow off acid-forming carbon dioxide, but they also reflexly increase blood pressure by sending stimulatory impulses to the cardiovascular centers. Blood pressure may fall when eliminating excess heat from the body even though baroreceptors reflex is for coetaneous vasoconstriction. Long-term Regulation of blood pressure: Long-term regulation of blood pressure involves many factors in addition to the integrated neural control of cardiovascular reflexes. The macula densa responds to sodium excretion and by some unknown mechanism, feedback this information to the juxtaglomerular cells, causing a rise in renin secretion, and corresponding retention a befitting response to increased sodium excretion in the urine. Its vasoconstrictor effect on arteriolar smooth muscles causes a sharp rise in peripheral resistance and hence arterial blood pressure. Aldosterone acts on the distal renal tubule to decrease the amount of NaCl excreted in to the urine. Thus blood volume rises, blood pressure increases, & rennin secretion is inhibited. Role of the renin-angiotensin system in arterial pressure control 208 Circulatory Shock Shockis a popular term used by the layperson to describe a sudden and severe setback due to any reason. But circulatory shock or cardiovascular collapseis characterized by a reduction in circulatory blood volume and results in inadequate tissue perfusion. Circulatory shock is the final common pathway for a number of potentially lethal clinical events including severe hemorrhage, extensive trauma or burns, large myocardial infarction, massive pulmonary embolism, and microbial sepsis. Hemorrhage generally leads to shock if more than 15 to 20% of the blood volume has been lost. With smaller losses, the compensatory mechanisms of the body are generally able to prevent shock. In burns, plasma is lost from capillaries, the permeability of which is increased. Instead, the vascular capacity increases so much that even the normal amount of blood becomes incapable of adequately filling the circulatory system. One of the major causes of this is sudden loss of vasomotor tone throughout the body, causing especially massive dilation of the veins. It is caused by: (a) Deep general anesthesia (b) Spinal anesthesia (c) Brain damage 5. Anaphylactic shock Some hypersensitivity reactions can lead to release of histamine or other substances, which produce vasodilation as well as increase in capillary permeability. This histamine, in turn, causes (a) Increase in vascular capacity (b) Dilatation of arterioles (c) Greatly increased capillary permeability 210 Table 18. Three major types of shock Type of shock Clinical examples Principal mechanisms >Myocardial infarction >Ventricular rupture >Failure of myocardial pump Cardiogenic >Arrhythmia due to >Cardiac tamponade intrinsic myocardial damage or >Pulmonary embolism extrinsic pressure or obstruction to outflow >Hemorrhage Hypovolemic >Fluid loss. Nonprogressive shock In this stage the normal circulatory compensatory mechanisms will eventually cause full recovery without help from outside therapy. In the early nonprogressive stage of shock, various neurohumoral mechanisms help maintain cardiac output and blood pressure. The net effect is tachycardia, peripheral vasoconstriction, and renal conservation of fluid. Progressive stage this is characterized by tissue hypoperfusion and onset of worsening circulatory and metabolic imbalances. Unless the progressive stage is intervened, the process eventually enters an irreversible stage. A rule of the thumb is to consider the blood pressure as normal if it is less than 100 + Age in years) mmHg. However, many specialists have evidence to believe that rise in blood pressure with age is a price we have to pay for our lifestyle, specially the high salt content of our diet. Some experts assert that if no 213 additional salt is added to our food throughout life, the blood pressure will stay constant throughout our life. Since this hypothesis cannot be widely tested on human beings at present stage of our civilization, we have to accept some rise in blood pressure as a part of the aging process. Although the change is gradual, and there is no sharp dividing line between the normal and high blood pressure, an arbitrary dividing line is required for clinical use. The arbitrary upper limits are 140 and 90 mmHg for systolic and diastolic blood pressure respectively. A mean arterial pressure greater than 110 mmHg under resting conditions usually is considered to be hypertensive. Adverse effects of hypertension the lethal effects of hypertension are caused mainly in three ways: (1) Excess workload on the heart leads to early development of congestive heart disease, coronary heart disease, or both, often causing death as a result of heart attack. It is known, however, that a number of factors interact in producing long-term elevations in blood pressure; these factors include: 214 Hemodynamic Neural Humoral Renal Arterial hypertension occurs when the relationship between blood volume and total peripheral resistance is altered. For many of the secondary forms of hypertension, these factors are reasonably well understood. For example, in renovascular hypertension, renal artery stenosis causes decreased glomerular flow and decreased pressure in the afferent arteriole of the glomerulus. Secondary hypertension Only 5% to 10% of hypertensive cases are currently classified as secondary hypertension that is, hypertension due to another disease condition. The disease states that most frequently give rise to secondary hypertension are: 216 (1) Renal disease (2) Vascular disorders (3) Endocrine disorders (4) Acute brain lesion.

800 mg aciclovir

For most outbreaks of vaccine-preventable illnesses antiviral used for rsv generic aciclovir 800mg mastercard, unvaccinated children should be excluded until they are vaccinated hiv aids infection rate washington dc trusted aciclovir 800 mg. Since administration of rotavirus vaccine was recommended routinely antiviral quiz 200mg aciclovir amex, disease and hospitalization for diarrhea attributable to rotavirus have decreased dramatically hiv infection rate chart purchase aciclovir 400mg otc. Salmonella species hiv infection blood test buy aciclovir cheap, Clostridium diffcile hiv infection through precum buy discount aciclovir on-line, and Campylobacter species infrequently have been associated with outbreaks of disease in children in child care. Most reptiles and many rodents (eg, hamsters, mice, rats) are colonized with Salmonella organisms, lympho cytic choriomeningitis virus, and other viruses that may be transmitted to children via contact (see Diseases Transmitted by Animals [Zoonoses]: Household Pets, Including Nontraditional Pets, and Exposure to Animals in Public Settings, p 215). Management of contact between young children and animals known to transmit disease to children is dif fcult in group child care settings. Optimal hand hygiene, especially after contact with animals and before eat ing or drinking, is essential to prevent transmission of zoonoses in the child care setting. Young children who are not toilet trained have an increased frequency of diarrhea and of fecal contamination of the environment. Enteropathogen spread is common in child care programs and is highest in infant and toddler areas, especially among attendees who are not toilet trained completely. Enteropathogens are spread by the fecal-oral route, either directly by person-to-person transmission or indirectly via fomites, environmental surfaces, and food, resulting in transmission of disease. The risk of food contamination can be increased when staff members who assist with toilet use and diaper-changing activities also prepare or serve food. To recognize outbreaks and initiate appropriate control measures, health care professionals and child care providers should be aware of this epidemiologic characteristic (see Hepatitis A, p 361). The single most important procedure to minimize fecal-oral transmission is frequent hand hygiene measures combined with staff training and monitoring of staff implemen tation. A child in whom jaundice develops should not have contact with other children or staff until 7 days after symptom onset. Possible modes of spread of respiratory tract viruses include aerosols, respiratory droplets, and direct hand contact with contaminated secretions and fomites. The incidence of viral infections of the respiratory tract is increased in child care settings. Hand hygiene measures can decrease the incidence of acute respira tory tract disease among children in child care (see Recommendations for Inclusion and Exclusion, p 136). Infuenza virus and rhinovirus have been detected on samples from toys, indicating that environmental sanitation may be important in decreasing the incidence of acute respiratory tract disease in children in child care. The occurrence of invasive disease attributable to H infuenzae type b (Hib) is rare since immunization of infants and children with Hib conjugate vaccine was recom mended routinely (see Haemophilus infuenzae infections, p 345). The age group experiencing the highest incidence is children younger than 1 year of age. Extended close contact between children and staff exposed to an index case of meningococcal disease predisposes to secondary transmission. Because outbreaks may occur in child care settings, chemoprophylaxis is indicated for exposed child care contacts (see Meningococcal Infections, p 500). In the prevaccine era, the risk of primary invasive disease attributable to S pneumoniae among children in child care settings was increased compared with children not in child care settings. Secondary spread of S pneumoniae in child care centers has been reported, but the degree of risk of secondary spread in child care facilities is unknown. Prophylaxis for contacts after an occurrence of one or more cases of invasive S pneumoniae disease is not recommended. Use of S pneumoniae conjugate vaccine has decreased dramatically the incidence of both invasive disease and pneumonia among children and other age groups not targeted for vaccination and has decreased carriage of serotypes of S pneu moniae contained in the pneumococcal conjugate vaccine. Group A streptococcal infection among children in child care has been reported, including an association with varicella outbreaks. A child with proven group A strepto coccal infection should be excluded from classroom contact until 24 hours after initiation of antimicrobial therapy. Although outbreaks of streptococcal pharyngitis in these set tings have occurred, the risk of secondary transmission after a single case of mild or even severe invasive group A streptococcal infection remains low. Chemoprophylaxis for con tacts after group A streptococcal infection in child care facilities generally is not recom mended (see Group A Streptococcal Infections, p 668). Infants and young children with tuberculosis disease are not as contagious as adults, because children are less likely to have cavitary pulmonary lesions and are unable to expel large numbers of organisms into the air forcefully. If approved by health care offcials, children with tuberculosis disease may attend group child care if the follow ing criteria are met: (1) chemotherapy has begun; (2) ongoing adherence to therapy is documented; (3) clinical symptoms have resolved; (4) children are considered noninfec tious to others; and (5) children are able to participate in activities. The need for periodic subsequent tuberculin screening for people without clinically important reactions should be determined on the basis of their risk of acquiring a new infection and local or state health department recommendations. Adults with symptoms compatible with tuberculosis should be evaluated for the disease as soon as possible. Child care providers with suspected or confrmed tuberculosis disease should be excluded from the child care facility and should not be allowed to care for chil dren until their evaluation is negative or chemotherapy has rendered them noninfectious (see Tuberculosis, p 736). Isolation or exclusion of immunocompetent people with parvovirus B19 infection in child care settings is unwarranted, because little or no virus is present in respiratory tract secretions at the time of occurrence of the rash of erythema infectio sum. In addition, because fewer than 1% of pregnant teachers during erythema infec tiosum outbreaks would be expected to experience an adverse fetal outcome, exclusion of pregnant women from employment in child care or teaching is not recommended (see Parvovirus B19, p 539). This is based on the equivalent risk of acquisition of parvo virus B19 from a community source not affliated with the child care facility. The epidemiology of varicella has changed dramatically since licensure of the varicella vaccine in 1995. In the prevaccine era, attendance in child care was a described risk factor for children acquiring varicella at earlier ages. Children with varicella who have been excluded from child care may return after all lesions have dried and crusted, which usually occurs on the sixth day after onset of rash. Immunized children with breakthrough varicella with only maculopapular lesions can return to child care or school if no new lesions have appeared within a 24-hour period. All staff members and parents should be notifed when a case of varicella occurs; they should be informed about the greater likelihood of serious infec tion in susceptible adults and adolescents and in susceptible immunocompromised people in addition to the potential for fetal sequelae if infection occurs during the pregnancy of a susceptible woman. Adults without evidence of immunity should be offered 2 doses of varicella vac cine unless contraindicated. Susceptible child care staff members who are pregnant and exposed to children with varicella should be referred promptly to a qualifed physician or other health care professional for counseling and management. During a varicella outbreak, people who have received 1 dose of varicella vaccine should, resources permitting, receive a sec ond dose of vaccine, provided the appropriate interval has elapsed since the frst dose (3 months for children 12 months through 12 years of age and at least 4 weeks for people 13 years of age and older). In immunocompetent people, herpes zoster lesions that can be cov ered pose a minimal risk, because transmission usually occurs as a result of direct contact with fuid from lesions (see Varicella-Zoster Infections, p 774). The highest rates (eg, 70%) of viral shedding in oral secretions and urine occur in children between 1 and 3 years of age, and excretion commonly continues (sometimes intermittently) for years. Therefore, use of standard precautions and hand hygiene are the optimal methods of prevention of transmission of infection. Although risk of contact with blood containing one of these viruses is low in the child care setting, appro priate infection-control practices will prevent transmission of bloodborne pathogens if exposure occurs. All child care providers should receive regular training on how to prevent transmission of bloodborne infections and how to respond should an exposure occur ( Indirect transmission through environmental contamination with blood or saliva is possible. This occurrence has not been documented in a child care setting in the United States. Because saliva contains much less virus than does blood, the potential infectivity of saliva is low. Infectivity of saliva has been demonstrated only when inoculated through the skin of gibbons and chimpanzees. The responsible public health authority or child care health consultant should be consulted when appropriate. Serologic testing generally is not warranted for the biting child or the recipient of the bite, but each situation should be evaluated individually. Toothbrushes and pacifers should be labeled individually and should not be shared among children. Information about a child who has immunodefciency, regardless of cause, should be available to care providers who need to know how to help protect the child against other infections. For example, immunodefcient children exposed to measles or varicella should receive postexposure immunoprophylaxis as soon as possible (see Measles, p 489, and Varicella-Zoster Infections, p 774). Written documentation of immunizations appropriate for age should be provided by parents or guardians of all children in out-of-home child care. Unless contraindica tions exist or children have received medical, religious, or philosophic exemptions, immunization records should demonstrate complete immunization for age as shown in the recommended childhood and adolescent immunization schedules (see Fig 1. Immunization mandates by state for children in child care can be found online ( Children who have not received recommended age-appropriate immunizations before enrollment should be immunized as soon as possible, and the series should be completed according to Fig 1. In the interim, permitting unimmunized or inadequately immunized children to attend child care should depend on medical and legal counsel regarding how to handle the risk and whether to inform parents of enrolled infants and children about potential exposure to this risk. These children place other children at risk of contracting a vaccine-preventable disease. If a vaccine-preventable disease to which children may be susceptible occurs in the child care program, all underimmunized chil dren should be excluded for the duration of possible exposure or until they have com pleted their immunizations. All adults who work in a child care facility should have received all immunizations routinely recommended for adults ( Child care providers should be immunized against infuenza annually and should be immunized appropriately against measles as shown in the adult immunization schedule. Child care providers are expected to render frst aid, which may expose them to blood. All child care providers should receive written information about hepatitis B disease and its complications as well as means of prevention with immunization. All child care providers should receive written information about varicella, particularly disease mani festations in adults, complications, and means of prevention. All adults who work in child care facilities should receive a one-time dose of Tdap (tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis) vaccine regardless of how recently they received their last dose of Td for booster immunization against tetanus, diphtheria, and pertussis. Pregnant women not immunized previously with Tdap should be immunized at more than 20 weeksgestation, or if not immunized during pregnancy, they should receive Tdap immediately postpartum. For other recommendations for Tdap vaccine use in adults, including unimmunized or partially immunized adults, see Pertussis (p 553) and the adult immunization schedule. Soiled dispos able diapers, training pants, and soiled disposable wiping cloths should be discarded in a secure, hands-free, plastic-lined container with a lid. Diapers should contain all urine and stool and minimize fecal contamination of children, child care providers, environ mental surfaces, and objects in the child care environment. Disposable diapers with absorbent gelling material or carboxymethylcellulose or single-unit reusable systems with an inner cotton lining attached to an outer waterproof covering that are changed as a unit should be used. Clothes should be worn over diapers while the child is in the child care facility. This clothing, including shoes, should be removed and placed where it will not have contact with diaper contents during the diaper change. The use of potty chairs should be dis couraged, but if used, potty chairs should be emptied into a toilet, cleaned in a utility sink, and disinfected after each use. Staff members should disinfect potty chairs, toilets, and diaper-changing areas with a freshly prepared solution of a 1:64 dilution of house hold bleach (one quarter cup of bleach diluted in 1 gallon of water) applied for at least 2 minutes and allowed to dry. These sinks should be washed and disinfected at least daily and should not be used for food preparation. Food and drinking utensils should not be washed in sinks in diaper changing areas. Handwashing sinks should not be used for rinsing soiled clothing or for cleaning potty chairs. Children should have access to height-appropriate sinks, soap dispensers, and disposable paper towels. Children should not have independent access to alcohol-based hand sanitizing gels or use them without adult supervision, because they are fammable and toxic if ingested because of their high alcohol content. Alcohol-based sanitizing gels should be limited to areas where there are no sinks. In general, routine housekeeping procedures using a freshly prepared solution of com mercially available cleaner (eg, detergents, disinfectant detergents, or chemical ger micides) compatible with most surfaces are satisfactory for cleaning spills of vomitus, urine, and feces. For spills of blood or blood-containing body fuids and of wound and tissue exudates, the material should be removed using gloves to avoid contamination of hands, and the area then should be disinfected using a freshly prepared solution of a 1:10 dilution of household bleach applied for at least 2 minutes and wiped with a dis posable cloth after the minimum contact time. Crib mattresses should have a nonporous easy-to-wipe surface and should be cleaned and sanitized when soiled or wet. Sleeping cots should be stored so that contact with the sleeping surface of another mat does not occur. Bedding (sheets and blankets) should be assigned to each child and cleaned and sanitized when soiled or wet. All frequently touched toys in rooms that house infants and tod dlers should be cleaned and sanitized daily. Toys in rooms for older continent children 1 Centers for Disease Control and Prevention. Soft, nonwashable toys should not be used in infant and toddler areas of child care programs.

Supplemental straps or sheets may be necessary to prevent flexion/extension of torso antiviral ointment purchase aciclovir with a mastercard, hips how long after hiv infection do symptoms show cheap aciclovir 200mg online, legs by being placed around the lower lumbar region hiv infection rates florida buy 400mg aciclovir fast delivery, below the buttocks hiv opportunistic infection guidelines buy generic aciclovir pills, and over the thighs hiv infection prophylaxis guidelines buy aciclovir on line, knees, and legs 55 c. Secure all four extremities to maximize safety for patient, staff, and others iii. Multiple knots should not be used to secure a device Patient Safety Considerations the management of violent patients requires a constant reevaluation of the risk/benefit balance for the patient and bystanders in order to provide the safest care for all involved. Do not attempt to enter or control a scene where physical violence or weapons are present 3. Uncontrolled or poorly controlled patient agitation and physical violence can place the patient at risk for sudden cardiopulmonary arrest due to the following etiologies: a. Excited delirium/exhaustive mania: A postmortem diagnosis of exclusion for sudden death thought to result from metabolic acidosis (most likely from lactate) stemming from physical agitation or physical control measures and potentially exacerbated by stimulant drugs. Positional asphyxia: Sudden death from restriction of chest wall movement and/or obstruction of the airway secondary to restricted head or neck positioning resulting in hypercarbia and/or hypoxia 6. Apply a cardiac monitor as soon as possible, particularly when pharmacologic management medications have been administered 7. All patients who have received pharmacologic management medications must be monitored closely for the development of hypoventilation and oversedation a. Patients who have received antipsychotic medication for pharmacologic management must be monitored closely for the potential development of: a. Dystonic reactions (this can easily be treated with diphenhydramine/benzodiazepines) b. Patients who are more physically uncooperative should be physically secured with one arm above the head and the other arm below the waist, and both lower extremities individually secured 11. For patients with key-locking devices, applied by another agency, consider the following options: a. Administer pharmacologic management medication then remove and replace device with another non-key-locking device after patient has become more cooperative c. Transport patient, accompanied in patient compartment by person who has key for the device d. Transport patient in vehicle of person with device key if medical condition of patient is deemed stable, direct medical oversight so authorizes, and law allows Pertinent assessment findings 1. Cardiac status, especially if the patient has received pharmacologic management medication f. Ketamine sedation is not associated with clinically meaningful elevation of intraocular pressure. The effect of ketamine on intraocular pressure in pediatric patients during procedural sedation. Successful management of excited delirium syndrome with prehospital ketamine: two case examples. Intranasal ketamine for procedural sedation in pediatric laceration repair: a preliminary report. Provide timely therapy for potentially life-threatening reactions to known or suspected allergens to prevent cardiorespiratory collapse and shock 2. Provide symptomatic relief for symptoms due to known or suspected allergens Patient Presentation Inclusion Criteria Patients of all ages with suspected allergic reaction and/or anaphylaxis Exclusion Criteria No recommendations Patient Management Assessment 1. Two or more of the following occurring rapidly after exposure to a likely allergen: 1. If signs of anaphylaxis, administer epinephrine 1mg/mL at the following dose and route: a. Epinephrine 1mg/mL may be administered from a vial or via auto-injector, if available, 3. As a supplement to diphenhydramine given for urticaria, any H2-blocking antihistamine. If stridor is present, consider administering epinephrine 1mg/mL, 5mL nebulized 6. Cardiac monitoring is not required, but should be considered for those with known heart problems or who received multiple doses of epinephrine Patient Safety Considerations 1. Allergic reactions and anaphylaxis are serious and potentially life-threatening medical emergencies. Cardiovascular collapse may occur abruptly, without the prior development of skin or respiratory symptoms. Contrary to common belief that all cases of anaphylaxis present with cutaneous manifestations, such as urticaria or mucocutaneous swelling, a significant portion of 61 anaphylactic episodes may not involve these signs and symptoms on initial presentation. Moreover, most fatal reactions to food-induced anaphylaxis in children were not associated with cutaneous manifestations. Gastrointestinal symptoms occur most commonly in food-induced anaphylaxis, but can occur with other causes a. Oral pruritus is often the first symptom observed in patients experiencing food-induced anaphylaxis b. Abdominal cramping is also common, but nausea, vomiting, and diarrhea are frequently observed as well 5. There is no proven benefit to using steroids in the management of allergic reactions and/or anaphylaxis 7. Predictors of hospital admission for food-related allergic reactions that present to the emergency department. Pharmacokinetics and pharmacodynamics of moist inhalation epinephrine using a mobile inhaler. Systemic absorption of adrenaline after aerosol, eye drop and subcutaneous administration to healthy volunteers. Can paramedics safely decide which patients do not need ambulance transport or emergency department care Anaphylaxis in a New York City pediatric emergency department: Triggers, treatments, and outcomes. Asthma and the prospective risk of anaphylactic shock and other allergy diagnoses in a large integrated health care delivery system. Confusion about epinephrine dosing leading to iatrogenic overdose: a life-threatening problem with a potential solution. Adrenaline auto-injectors for the treatment of anaphylaxis with and without cardiovascular collapse in the community. Can paramedics accurately identify patients who do not require emergency department care Epinephrine for the out-of-hospital (first-aid) treatment of anaphylaxis in infants: is the ampule/syringe/needle method practical Can epinephrine inhalations be substituted for epinephrine injection in children at risk for systemic anaphylaxis Clinical features of children with venom allergy and risk factors for severe systemic reactions. Protect patient from harm Patient Presentation Inclusion Criteria Impaired decision-making capacity Exclusion Criteria Traumatic brain injury Patient Management Assessment Look for treatable causes of altered mental status: 1. Chest/Abdominal Intra-thoracic hardware, assist devices, abdominal pain or distention 12. Extremities/skin Track marks, hydration, edema, dialysis shunt, temperature to touch (or if able, use a thermometer) 13. Environment Survey for pills, paraphernalia, ambient temperature Treatment and Interventions 1. Restraint: physical and chemical [see Agitated or Violent Patient/Behavioral Emergency guideline] 5. Anti-dysrhythmic medication [see Cardiovascular Section guidelines for specific dysrhythmia guidelines] 6. Active cooling or warming [see Hypothermia/Cold Exposure or Hyperthermia/Heat Emergency guidelines] 7. With depressed mental status, initial focus is on airway protection, oxygenation, ventilation, and perfusion 2. The violent patient may need pharmacologic and/or physical management to insure proper assessment and treatment 3. Hypoglycemic and hypoxic patients can be irritable and violent [see Agitated or Violent Patient/Behavioral Emergency guideline] Notes/Educational Pearls Key Considerations 1. Duration of hypotension before initiation of effective antimicrobial therapy is the critical determinant of survival in human septic shock. Prospective study of patients with altered mental status: clinical features and outcome. Prehosp Emerg Care, 2013 Apr-Jun; 17(2): 230-4 Revision Date September 8, 2017 68 Back Pain Aliases None Patient Care Goals 1. Identify life-threatening causes of back pain Patient Presentation Inclusion Criteria Back pain or discomfort related to a non-traumatic cause or when pain was due to non-acute trauma. Back pain due to sickle cell pain crisis [see Sickle Cell Pain Crisis guideline] 3. Obtain vascular access as necessary to provide analgesia and/or fluid resuscitation 5. Reassess vital signs and response to therapeutic interventions throughout transport Patient Safety Considerations No recommendations Notes/Educational Pearls Key Considerations 1. Consider transport to appropriate specialty center if aortic emergency suspected 4. Identify patients on anticoagulants since they are higher risk for spinal epidural hematoma or retroperitoneal hemorrhage which can present as back pain 6. Absence of or significant inequality of femoral or distal arterial pulses in lower extremities 6. Exclusion Criteria Complaints unrelated to the illness for which the patient is receiving those services. If the patient is able to communicate and has the capacity to make decisions regarding treatment and transport, consult directly with the patient before treatment and/or transport 3. If the patient lacks the capacity to make decisions regarding treatment and/or transport, identify any advanced care planning in place for information relating to advanced care planning and consent for treatment a. In collaboration with hospice or palliative care provider, coordinate with guardian, power of attorney, or other accepted healthcare proxy if non-transport is considered Patient Safety Considerations 1. Careful and thorough assessments should be performed to identify complaints not related to the illness for which the patient is receiving hospice or palliative care 2. Care should be delivered with the utmost patience and compassion Notes/Educational Pearls Key Considerations 1. Scene safety should be considered when deciding on management Pertinent Assessment Findings 1. Appropriate hydration for hyperglycemia Patient Presentation Inclusion Criteria 1. Adult or pediatric patient with altered level of consciousness [see Altered Mental Status guideline] 2. Adult or pediatric patient with history of diabetes and other medical symptoms Exclusion Criteria Patient in cardiac arrest. Evaluate for possible concomitant sepsis and septic shock [see Shock guideline] 4. If altered level of consciousness, stroke, or sepsis/septic shock, treat per Altered Mental Status, Suspected Stroke/Transient Ischemic Attack, or Shock guidelines accordingly 2. If glucose greater than 250 mg/dL with symptoms of dehydration, vomiting, abdominal pain, or altered level of consciousness: a. If mental status changes, reassess blood glucose level and provide appropriate treatment if hypoglycemia has developed 6. Transport to closest appropriate receiving facility Patient Safety Considerations 1. Overly aggressive administration of fluid in hyperglycemic patients may cause cerebral edema or dangerous hyponatremia a.
