The disease fact sheets depression hotline chat discount abilify 20mg amex, which comprise most of this document, are intended to familiarize people with specific infectious disease problems commonly encountered in childcare. The fact sheets can be easily photocopied for distribution to parents and guardians. In the event that any of the illnesses mentioned in this manual occur among children attending childcare, parents or guardians should be promptly notified by the childcare provider and urged to contact their family physician to obtain specific medical care advice. Childcare directors should immediately notify the Bureau of Infectious Disease Control concerning any unusual disease occurrence in their facilities so that appropriate disease-control measures may begin promptly. Also, special thanks to the many childcare providers who gave us valuable input on the content, organization and design of this manual.

Age appropriate recommended for childcare attendance per routine childhood vaccination schedule. Prior to immunization programs, these diseases were a major cause of widespread illness, often with permanent medical complications and even death. Most of these diseases were a problem especially in children, although adults were also affected. Specific information about immunization schedules can be found on the Immunization Requirements Section in this handbook and on the appropriate fact sheets. It is recommended that all adults working in a childcare setting, including volunteers, should have proof of immunization or immunity to the following vaccinepreventable diseases: diphtheria, tetanus, pertussis, measles, mumps, rubella, hepatitis B, varicella, and polio. Although evidence of such immunization or immunity is not required for childcare workers, they are strongly recommended. If a documented case of measles, mumps, rubella, polio, diphtheria, tetanus, varicella or pertussis occurs in your childcare facility, you must notify the New Hampshire Division of Public Health Services, Bureau of Infectious Disease Control. Their staff will assist you in starting any necessary identification and vaccination of susceptible children and adults. They will also instruct you on procedures for closely watching for any additional cases and for notifying the parents. Cases of these diseases do occur, particularly in unimmunized or inadequately immunized children and adults. This is because the children may be too young to be fully immunized and because the close contact that occurs in childcare facility allows easy spread of many diseases. Although it is unlikely that you will ever see a case of most of these diseases, it is very important that you be aware of them and of your vital role in preventing their spread. A one-time dose of Tdap is now the vaccine of choice for any adult regardless ofage who is due for a Td booster. Anyone who has close contact with infants less than 12 months of age should have the Tdap at least one month prior to contact. It is suggested an interval of 2 years or more since the last dose of Td, as the minimum interval prior to the administration of Tdap. Hepatitis B Documentation of 3 doses of hepatitis B vaccine given at appropriate intervals (or) laboratory evidence of immunity is recommended. Measles Born before 1957 (or) documentation of vaccination with at least two doses of live measles vaccine, with the first dose given on or after the first birthday and the second live dose at least 28 days from the first (or) laboratory evidence of immunity. Influenza One dose of influenza vaccine is highly recommended annually for all childcare workers. Mumps Documentation of vaccination with live mumps vaccine on or after the first birthday (or) laboratory evidence of immunity (or) documentation of physician-diagnosed mumps is recommended. Rubella Documentation of vaccination with rubella vaccine on or after the first birthday (or) laboratory evidence of immunity is recommended. The parent, legal guardian or other authorized by the parent shall be notified immediately when a child has a sign or symptom requiring exclusion from the facility, as described below: a) the illness prevents a child from participating comfortably in facility activities; b) the illness results in a greater care need than the childcare staff can provide without compromising the health and safety of the other children; or c) the child has any of the following conditions: 1. Temperature: Oral temperature 101 F or greater; rectal temperature 102 F or greater; axillary (i. Oral temperature shall not be taken on children younger than 4 years (or younger than 3 years if a digital thermometer is used). Symptoms and signs of possible severe illness (such as unusual lethargy, uncontrolled coughing, irritability, persistent crying, difficult breathing, wheezing, or other unusual signs), until medical evaluation allows inclusion. Uncontrolled diarrhea, that is, increased number of stools, increased stool water, and/or decreased form that is not contained by the diaper, until diarrhea stops. Vomiting illness (two or more episodes of vomiting in the previous 24 hours) until vomiting resolves or until a healthcare provider determines the illness to be noncommunicable, and the child is not in danger of dehydration. Rash with fever or behavior change, until a healthcare provider determines that these symptoms do not indicate a communicable disease. Rationale: Exclusion of children with many mild infectious diseases is likely to have only a minor impact on the incidence of infection among other children in the group. Thus, when formulating exclusion policies, it is reasonable to focus on the needs and behavior of the ill child and ability of staff in the out-of-home childcare setting to meet those needs without compromising the care of other children in the group. Chicken pox, measles, rubella, mumps and pertussis are highly communicable illnesses for which routine exclusion of infected children is warranted. It is also appropriate to exclude children with treatable illnesses until treatment is received and until treatment has reduced the risk of transmission. The presence of diarrhea, particularly in diapered children, and the presence of vomiting increase the likelihood of exposure of other children to the infectious agents that cause these illnesses. It may not be reasonable to routinely culture children who present with fever and sore throat or diarrhea. Life-threatening diseases, such as meningitis, cause a small proportion of childhood illness with fever. Generally, young infants show less fever with serious illness than older children. Infants and children older than 4 months should be excluded whenever behavior changes and/or signs or symptoms of illness accompany fever. Infants 4 months old or younger should be excluded when rectal temperature is 101 F or above, or axillary (i. It is unreasonable and inappropriate for childcare staff to attempt to determine which illnesses with fevers may be serious. Childcare providers who have herpes cold sores should not be excluded from the childcare facility, but should: 1) Cover and not touch their lesions; 2) Carefully observe handwashing policies; 3) Refrain from kissing or nuzzling infants or children, especially children with dermatitis. Excerpted from Care For Our Children, National Health and Safety Performance Standards: Guidelines for Out-Of-Home Childcare Programs, American Public Health Association, 2011. The prevention and identification of child abuse and neglect is a community responsibility that depends on the cooperation of all community members. In situations where abuse, neglect or sexual abuse is suspected or if discussion with the family does not relieve concerns, then the Division for Children, Youth and Families should be contacted at 603-271-6562 or 1-800-894-5533 (In state only) 24 hours per day. It is better to make your concerns known than to remain silent and possibly allow a child to be seriously harmed. If the organisms, which cause infectious diarrhea, hepatitis-A, giardiasis and other illnesses, are accidentally ingested, the disease may be transmitted.
The definition of high factor loading is also subject to anxiety attack vs panic attack order abilify 20mg visa researcher interpretation and can vary from 0 anxiety gif buy 15 mg abilify fast delivery. More recently hysterical depression definition discount abilify online american express, however anxiety uncertainty theory generic abilify 20 mg without a prescription, it has become accepted that data collection methods are not always linked solely to a single research paradigm and interviews have become recognised for their broader application in mixed methods research(18). Telephone interviews were chosen for this study in preference to face-to-face interviews or focus groups in order to facilitate the inclusion of nurses from a wide geographical distribution, to encourage participation by conducting the discussion at a time suitable to the participant without the need to travel and as a relatively costeffective method of achieving these aforementioned aims(62, 64, 65). Telephone interviews have been demonstrated to be an acceptable method of collecting information from nurses in several studies(64, 66, 67). Additionally, those nurses who had been discouraged by their employers to complete the survey were able to freely participate in the telephone interviews in their own time, if they desired. Despite the relative advantages and disadvantages of telephone interviews discussed below, few inconsistencies in data quality have been observed and reported between face-to-face and telephone interviews(68). The combination of postal survey and telephone interview has also been successfully utilised to provide a more comprehensive and complete dataset as was the underlying premise of this research design(6, 7, 26). A major reported disadvantage of the telephone interview is the absence of visual cues and inability to view the body language of the participant, which creates the potential for misinterpretation by the interviewer(64, 65, 69). The fact that the topic area was not particularly sensitive in nature and the expectation that responses would not involve in-depth emotional responses potentially reduced this effect. A further consideration is that since the participants were professional peers of the interviewer, the perceived anonymity created by talking over the telephone may have actually enhanced the richness of the data as the participant felt more at ease(62, 65, 69). At the outset of the interviews, however, participants were advised that they could ask the interviewer to take a break at any stage during the discussion. Worth and Tierney(71) assert that there may be difficulties in conducting telephone interviews where the researcher has not developed a prior relationship with the participant. Since participants in these interviews were recruited following their involvement with the survey component of the study, they did have some prior relationship with the researcher. Effort was made during the contacts involved in setting up the interviews to foster a greater sense of relationship between the participant and researcher. The initial discussion of the telephone contact in which the interview was undertaken was also utilised to foster a sense of relationship between the practice nurse and interviewer. The final consideration in telephone interviewing is the potential technical mishaps that can affect the flow of the interview and subsequent data quality(69, 72). Technical difficulties related to recording equipment are problematic in all types of recorded interviews. The potential to lose valuable data through errors in recording can clearly be disastrous. In telephone interviews, however, additional technical difficulties are apparent in terms of establishing and maintaining telephone connections. Technical aspects of interviewing over the telephone were carefully considered before the commencement of the interviews. Care was taken by the researcher to locate themselves in a quiet room, away from interruptions and to arrange appointments with participants at a time convenient to them that would avoid undue distraction(65). Field notes were made during the interviews, although care was taken when recording these notes to avoid disturbing the flow of the interview by undue distraction of the researcher(69, 73). At the conclusion of each interview, the field notes were reviewed to ensure the essence of each conversation was captured(73). Coding of field notes and audiotapes was undertaken to facilitate subsequent analysis. This was considered particularly important in this investigation where there were a significant number of interviews conducted by more than one interviewer. In contrast to the informal conversational interviews used in the pure qualitative approach or the rigid scripted interviews used in pure quantitative designs, mixed methods interviews tend to utilise an interview guide or semistructured research approach (Figure 4-2)(18, 73). In light of these considerations, semistructured interview guidelines were formulated from a combination of the literature review, expert key informant consultation and the preliminary survey findings. These guidelines contained a series of open-ended questions that were posed to each participant during the telephone conversation. Seidman(72) identifies that open-ended questions are problematic in that respondents may not provide sufficiently detailed responses. Standard stems and probes were, therefore, developed and included within the guidelines(69). The stems assisted by providing a consistent context for the interview questions, and the probes encouraged participants to continue, expand on, or clarify their responses(69). The aim of this process was to identify any problems or issues in the interviews and provide clarification before completion of the data collection. Issues identified included a need to probe more deeply to explore issues raised by the participants and a need to seek clarification on the intended meaning behind some responses given. Once contact details were received, an information sheet and consent form (Appendix I) were posted to the potential participant. Many investigations report that they audiorecord interviews for subsequent analysis and then somehow transform this audiotaped data into written text for subsequent analysis(60, 76). Whilst several papers discuss how to manage interview transcripts(62, 77), the contemporary literature provides limited direction and guidance regarding the specifics of the transcription and data management process(60, 63, 73, 76, 78). This is a substantial gap in the literature considering the significance of the management of verbal data to the reliability and validity of the research process(73). Wellard(60) asserts that transcription forms part of the data analysis process and should be clearly disclosed in the study methods. It is, therefore, essential for a transcription method to be employed that is congruent with the theoretical underpinnings of the specific investigation. This observation identifies the potential to employ alternate processes for managing verbal interview data other than conventional verbatim transcription techniques provided that they are consistent with the underlying philosophy of the methodology(73). Given the mixed methods nature of the investigation a reflexive, iterative process was employed to manage the audiotaped data(73). Audiotaping of Interview and Concurrent Note Taking the combined process of audiotaping and making field notes during qualitative research is not new(61). Reflective Journaling Immediately Post-interview As soon after the interview as possible, to ensure that reflections remain fresh, the researcher reviewed their field notes and expand on their initial impressions of the interaction with more considered comments and perceptions. Reflections on the conduct of the interview and extraneous variables particular to the interaction were also noted. Listening to the Audiotape and Revising Field Notes and Observations After the researcher completed their field notes and reflective journaling, the audiotape was reviewed in consultation with the field notes. The purpose of this phase was to ensure that the notes provide an accurate reflection of the interaction. This required the researcher to listen to the audiotape several times, comparing it with the field notes and amending the notes until they provided a thorough and descriptive account of the interaction. Preliminary Content Analysis Once the researcher was confident that their field notes accurately represented the separate interactions, the process of content analysis was used to elicit common themes between interviews. Where the interview data are being utilised to provide confirmation or completion of an existing dataset, as is the case in this investigation, the datasets should be considered together to explore similarities and differences. Secondary Content Analysis the preliminary content analysis was reviewed by a second member of the research team, who has not previously been involved in the data collection, through a thorough review of both audiotapes and field notes. This task tested the audit trail and validates the development of themes from the data. The specific strategies to enhance data quality in this study are discussed below. As has been discussed in this Chapter, the use of telephone interviews has complemented the breadth and depth of data collection through the surveys. Using a between-methods approach has enabled a broad range of issues to be crosschecked, thereby achieving convergent validity and confirmation of the data. Additionally, the complementary nature of the interviews has provided a level of enhancement and elaboration of findings from the survey that would not have been possible from using a single method in isolation(9). In this study, member checking was undertaken through the use of the survey findings to stimulate the question route for the telephone interviews. Concepts that appeared to be important from survey analysis were checked and then further explored during telephone conversations. The relatively large sample size involved in the survey and the previously discussed geographical distribution precluded member checking by all survey participants. Such debriefing also provides the researcher with an opportunity to test their evolving insights and to be exposed to searching questions about the study(12).

An average of 10 mL per kg four to depression verses purchase generic abilify from india six hours in the emergency department or an should be added for every loose stool or episode of vomit- overnight stay in the hospital. Depending on the severity of dehydration, a child might need two intravenous lines or Moderate to Severe Dehydration an intraosseous line. A rapid fluid bolus is given at a rate Moderate to severe dehydration usually requires hos- of 20 mL per kg of body weight. A bolus of 10 mL per kg pitalization, although oral rehydration therapy can be attempted in the emergency department using a syringe or a nasogastric tube if the infant or child refuses to drink. Urinary output and serum electrolyte, blood urea nitrogen, creatinine, and serum glucose levels should be checked often. Maintenance fluids should be given at a daily rate of 100 mL per kg for the first 10 kg, 50 mL per kg for the next 10 kg, and 20 mL per kg for the next 10 kg. Probiotics degrade and modify dietary antigens and balance the anti-inflammatory response of cytokines. There was no significant decrease in the number of children requiring intravenous fluids. There was no effect on the number of children admitted to the hospital, on fever or its duration, or on vomiting or its duration. Loperamide (Imodium) inhibits intestinal motility and can affect electrolyte and water movement through the bowel. Although loperamide is commonly used for gastroenteritis in older children, there are limited data to support it. The use of regular soap was most beneficial, and antibacterial soap provided little additional benefit. Contraindications to the vaccine in infants are hypersensitivity to the vaccine, gastrointestinal tract congenital malformation, and severe combined immunodeficiency. The live virus is shed in the stool of 25 percent of infants who receive the vaccine and could be transmitted to an unvaccinated contact. These vaccines have not been associated with an increased risk of intussusception at 30- and 42-day intervals, respectively. However, in Mexico, vaccination with Rotarix would prevent 11,551 hospitalizations and 663 childhood deaths from rotavirus while causing two additional deaths and 41 additional hospitalizations from intussusception.

Please consult a health care provider for any situations which require medical attention. Outbreaks or unusual situations may require additional control measures to be instituted/implemented in consultation with your local health department. The procedures in this document represent measures specific to school, child care or youth camp settings. This document is intended to guide the development of specific local policy and procedures regarding management of communicable diseases in schools, child care, and youth camps. These policies and procedures should be implemented in collaboration and in consultation with local health departments, school health services programs, local child care authorities and youth camp regulatory authorities. Definitions: Outbreak: In general, an outbreak is defined as an increase in the number of infections that occur close in time and location, in a facility, such as a school, child care center, or youth camp, over the baseline rate usually found in that facility. Many facilities may not have baseline rate information, if you have questions, please contact your local health department about whether a particular situation should be considered an outbreak. In some cases, the health department may require longer exclusions than stated in this guide in response to an outbreak. The level of use will always depend on the nature of the anticipated contact: o Handwashing, the most important infection control method o Use of protective gloves, latex-free gloves are recommended* o Masks, eye protection and/or face shield o Gowns o Proper handling of soiled equipment and linen o Proper environmental cleaning o Proper disposal of sharp equipment (e. Maryland Department of Health and Mental Hygiene, November 2011 -3- Communicable Diseases Summary: Guide for Schools, Child Care, and Youth Camps Fever: For the purposes of this guidance, fever is defined as a temperature >100. Diarrhea: Loose or watery stools of increased frequency that is not associated with change in diet. General Considerations: Exclusion: Children may be excluded for medical reasons related to communicable diseases or due to program or staffing requirements. In general, children should be excluded when they are not able to fully participate with the program, or in the case of child care settings, when their level of care needed during an illness is not able to be met without jeopardizing the health and safety of the other children, or when there is a risk or spread to other children that cannot be avoided with appropriate environmental or individual management. In addition, any child with a fever and behavior changes or other symptoms or signs of an acute illness should be excluded and parents notified. Also, it is important to be sure the appropriate method for measuring temperature is used based on the age or developmental level of the child. An unexplained fever in any child younger than 3 months requires medical evaluation. Fever in an infant the day following an immunization known to cause fever, may be admitted along with health care provider recommendations for fever management and indications for contacting the health care provider. Instructions from the health care provider should include: the immunizations given, instructions for administering any fever reducing medication, and medication authorizations signed by the parent and the health care provider. Diarrhea: Diarrhea may result in stools that are not able to be contained by a diaper or be controlled/contained by usual toileting practices. An infectious cause of diarrhea may not be known by the school, child care facility, or camp at the time of exclusion or return. A child with diarrhea should be excluded if: o Stool is not able to be contained in a diaper or in the toilet, or child is soiling undergarments o Stool contains blood o Child is ill or has any signs of acute illness o Diarrhea is accompanied by fever o Child shows evidence of dehydration (such as reduced urine or dry mouth) With appropriate documentation, a child with diarrhea may be readmitted to care, school, or camp when: o An infectious cause of diarrhea (see chart) has been treated and the child is cleared by a health care provider, in conjunction with the local health department, if necessary o the diarrhea has been determined by the local health department to not be an infectious risk to others Vomiting: An infectious cause of vomiting may not be known by the school, child care facility, or camp at the time of exclusion or return. Child should be excluded until vomiting resolves or until a health care provider clears for return (is not contagious). Period of Communicability N/A Exclusion (Yes or No) and Control Measures No, exclusion is not routinely recommended as long as student/child does not meet any other exclusion criteria. No, exclusion is not routinely recommended as long as student/child does not meet any other exclusion criteria. Other Information After immediate needs of bitten victim(s) are taken care of, notify local health department and appropriate local authority (police, sheriff, animal control) immediately by telephone. N/A After immediate needs of bitten victim(s) are taken care of, notify Responsible authority and parent/guardian. Assess immunization status of children involved, including tetanus and Hepatitis B vaccination. Symptoms May be asymptomatic; genital infection can include: purulent discharge, painful urination, lower abdominal pain.
One must keep in mind the potential for prolonged duration of action and the need for post-procedure ventilation depression in pregnancy cheap abilify american express. This means the patient should maintain at least one pretetanic twitch in a train of four depression definition anatomy cheap abilify 20mg amex. The basic technique involves using one of a variety of agents to depression definition symptoms and treatment order abilify australia achieve a deeper plane of anesthesia than is typical for the particular case in a non-myasthenic patient mood disorder treatment center trusted 10mg abilify. Bear in mind that all of these agents have the potential to cause hypotension and may need to be countered by a pressor agent (usually a vasoconstrictor such as phenylephrine). Optimization of neuromuscular function preoperatively is paramount for successful perioperative outcome. Anesthetically, we need to limit any agents we administer during surgery that may inhibit muscular strength or depress respiratory function. The struggle is to combine optimum preoperative treatment with effective intraoperative management such that the patient can emerge from anesthesia with peak strength and have limited or no respiratory compromise. Aminoglyciodes may be administered for perioperative infection or infection prophylaxis. These drugs can lead to weakness by themselves or prolong muscle relaxant action when administered during the case. This combined effect, together with the baseline neuromuscular dysfunction in myasthenic patients, makes it critical that narcotics be given in a monitored setting. Narcotic analgesics are very effective and necessary to treat postoperative pain, even in myasthenic patients. Other modalities of postoperative pain management are useful in myasthenic patients. Regional anesthetics (nerve blocks, epidurals, spinals) might be useful for certain procedures and can often be both the anesthetic and postoperative mode of analgesia. The benefits of these modalities need to be weighed against the unique risk of myasthenic patients. For example, spinal anesthesia to the level of T4 in a normal patient may be sensed as mild shortness of breath in normal patients. This is due to some of the accessory respiratory muscles being impaired by neuromuscular blockade to the T4 spinal nerve level. Next, case reports of thoracic epidurals for thymectomy in myasthenics have been linked to profound bradycardia. While these are usually rare occurrences, these examAnesthesia Issues ples illustrate that there is no single and simple method to caring for these complex patients. What is emerging from the data, though, is that what is given for anesthesia is not as important as how anesthesia is administered (with the exception of muscle relaxants). Della Rocca, et al (Della Rocca G, 2003) demonstrated that patients maintained during anesthesia with either sevoflurane (an inhaled anesthetic) compared to those maintained with propofol (an intravenous anesthetic) were equally successful at being immediately extubated postoperatively. The rate and type of postoperative complications were both minimal and similar in both groups. The foundation (as emphasized throughout this text) is to avoid muscle relaxants and preserve ventilatory function throughout anesthesia when at all possible. Banoub and Kraenzler (Banoub M, 2001) state that pyridostigmine doses of >750 mg/day place a patient at highest risk for postoperative ventilation, while Mori et al (Mori T,2003) showed risk of postoperative reintubation and ventilatory support to be strongly related to a dose of only 240mg/day. Medical management, including cholinesterase inhibitor medications, intravenous immunoglobulin therapy and plasma exchange are effective at treating and alleviating myasthenia gravis symptoms. Thymectomy has been shown to either cure or reduce symptoms in a significant number of patients. Banoub and Kraenzler (Banoub M, 2001) more generally state that thymectomy, in combined age reporting, produces 20% remission, 40% marked clinical improvement with reduced cholinesterase inhibitor use, 20% clinical improvement with no change in preoperative medication dosage, while 6% have no benefit. Symptomatic patients should take their cholinesterase inhibitor medications up to the point of surgery. Those patients who require plasma exchange should have it as close to the surgical date as possible. Muscle relaxants should be avoided, if possible, or titrated closely with the use of neuromuscular twitch monitoring. Following surgery, these patients should be followed in an intensive care setting to allow close respiratory monitoring, surgical blood loss recording and to provide the safest environment for intensive but closely monitored analgesic administration. Virtually any medication administered during the perioperative period can have potentially adverse effects for the patient. Surgery and anesthesia may impair, either physically or pharmacologically, respiratory function. Postoperative pain management and neuromuscular monitoring require specialized and intensive care. A strong understanding of medication pharmacology, myasthenia gravis pathophysiology and teamwork will allow these patients to be treated effectively and safely. Putting our egos aside and asking for assistance when caring for these patients is of utmost 93 Anesthesia Issues importance. Changes in respiratory condition after thymectomy for patients with myasthenia gravis. Vecuronium dose response and maintenance requirements in patients with myasthenia gravis. Propofol or sevoflurane anesthesia without muscle relaxants allow the early extubation of myasthenic patients. The prevalence of disease is about 20 per 100000 population, and the incidence is 2 to 5 cases / yr / 1000000 population. Prompt and correct identification and treatment of the myasthenic patient in the emergency department is critical. The stable myasthenic patient with unrelated issues the first scenario is the most common. In these patients, the challenge for the emergency practitioner is to identify the presence of the disease through history taking, and to avoid therapies that may aggravate the weakness. The second scenario is discussed below under Myasthenic Exacerbation and Myasthenic Crisis. The third scenario, although uncommon, represents a diagnostic challenge for the emergency practitioner that can be answered by careful history taking, evocative physical examination techniques, and bedside confirmatory testing. This temporal variation is often not noticed or spontaneously reported by patients. The examiner must elicit this key element of the history through directed questions to reveal symptoms that are worse at the end of the day, following exertion, or after prolonged activity. The most common symptoms of myasthenia include ptosis or diplopia, which together account for two thirds of all presenting complaints. Ptosis often begins as a unilateral or asymmetric problem that can be unnoticed by the patient but revealed in photographs. Diplopia is usually variable and worse with activities requiring sustained gaze (watching television, driving, reading). Limb weakness may be frank, subtle (such as stumbling when walking over rough and uneven surfaces), or vague (exercise intolerance). Respiratory symptoms and respiratory failure are uncommon presenting symptoms, although many patients have measurable respiratory weakness. When formal breathing capacity tests are not immediately available, screening can be done at the bedside by having the patient count slowly upwards from 1. Elevation of the head of the bed to 30 degrees or more may reduce aspiration risk, intrathoracic pressure, and work of breathing. Routine general and neurologic examinations may be augmented by provocative physical examination techniques. Ptosis and ophthalmoplegia may be elicited by asking the patient to maintain gaze for 180 seconds. In the emergency department, two methods are recommended to aid in the diagnosis of myasthenia gravis: the ice pack test, and the edrophonium (Tensilon, Reversol, Enlon) test (see Section 2. In patients with unilateral or bilateral ptosis, a bag or surgical glove filled with ice and wrapped in a towel is placed over the ptotic eye for 2 minutes. The degree of ptosis can also be measured by considering the iris as a clock face and noting where on the face of this clock the lid intersects the iris. The test is reported to be 80% sensitive, and highly specific for myasthenia gravis. Edrophonium chloride is a cholinesterase inhibitor with an effective duration of action of less than five minutes.
