Treat Infection Many different infections cause delirium or coma acne face map discount 5 mg curakne fast delivery, and infection may exacerbate coma from other causes skin care zarraz paramedical buy cheap curakne 30mg line. Draw blood cultures on all febrile patients and those who are hypothermic without obvious cause. As indicated in Chapter 3, if there is a strong suspicion of bacterial meningitis, empiric antibiotic therapy should begin immediately after blood cultures are drawn. In one large series of patients with sepsis treated in intensive care units, cultures were positive in only 60% of patients. A third-generation cephalosporin (cefotaxime, 2 g every 6 hours or ceftriaxone 2 g every 12 hours) should be started. In elderly or obviously immunosuppressed patients, ampicillin should be added to cover Listeria monocytogenes. Current evidence suggests that dexamethasone added to the regimen decreases long-term complications of the infection. In immunosuppressed patients, fungal and parasitic infections must also be considered, but because they tend to be less acute, they can await evaluation by imaging and spinal fluid examination. Other infections causing coma (Chapter 5) must Adjust Body Temperature Several metabolic and structural abnormalities lead to either hyperthermia or hypothermia, and these states may exacerbate abnormalities of cerebral metabolism. Significant hypothermia (below 348C) can lead to pneumonia, cardiac arrhythmias, electrolyte disorders, hypovolemia, metabolic acidosis, impaired coagulation, and thrombocytopenia and leukopenia. Administer Specific Antidotes Many patients entering an emergency room in coma are suffering from drug overdose. Empiric addition of amoxicillin is indicated for meningitis caused by Listeria monocytogenes. Continuation or change of antibiotics is guided by the results of cerebrospinal fluid analysis, blood culture, bacterial sensitivity to antibiotics, and clinical status of the patient. Steroid treatment in meningitis is unlikely to be of benefit if the diagnosis is delayed, if antibiotics have not been given, or if meningitis is Gram-negative bacillar or requires aminoglycoside antibiotics. Unless pneumococcal meningitis is proven or strongly suspected, dexamethasone use is not recommended in immunosuppressed or malnourished patients and in patients with other system infections. Most drug overdoses are best treated by the supportive measures considered in a subsequent section. Because these patients have ingested multiple agents, specific antagonists are often not useful. This drug must be used with great care, because in a patient physically dependent on opioids, the drug may cause acute withdrawal symptoms requiring opioid therapy. One should use the minimum amount necessary to establish the diagnosis by pupillary dilation and reverse the comatose state. Thus, patients who have taken an overdose of opioids, and whose toxic reactions are reversed by naloxone, may lapse back into coma after a few hours and require further treatment. Benzodiazepine overdose can be treated with flumazenil, a specific competitive benzodiazepine receptor antagonist41 (0. However, the drug is not often used because it can precipitate acute withdrawal in chronic users and blockade of the benzodiazepine receptor may unmask epileptogenic features of common medications such as tricyclic antidepressants or theophylline.

Physical restraints should be avoided whenever possible, but sometimes they are necessary for severely agitated patients. Take care to ensure that body restraints do not interfere with breathing and that limb restraints do not occlude blood flow or damage peripheral nerves.

Furthermore, when used in the home as post-exposure prophylaxis, they are extremely effective in preventing influenza illness, with efficacies of 74% and 90%, respectively. When outbreaks occur it is always in the context of a wider community epidemic, which for parainfluenza virus usually runs from May to September each year. Thus, it is possible that what may appear to be an outbreak is merely the result of multiple introductions of virus into the ward by patients, staff and visitors. How virus may be transmitted is not easy to determine with absolute confidence, but transmission by unwashed hands, contaminated fomites and large droplets are all possible. This emphasises the absolute necessity for extreme vigilance when adhering to hand-washing and for prolonged periods when patients are immune-compromised. Indeed, virus excretion for 4 months has been demonstrated in this patient group (Zambon et al. What was also clear from this study, and another in Canada, is that hospital parainfluenza virus outbreaks can, unlike those due to influenza where the median duration is only 7 days, be protracted and ultimately only terminated by closure of the unit to new admissions (Moisiuk et al. When the first case of a parainfluenza virus is discovered on a ward, especially those with highrisk patients, full adherence to all necessary infection control measures (gowns, gloves, patient cohorting and hand-washing), including reiterating the standing instructions to staff not to come to work if unwell, must be rigorously enforced. All precautions against airborne, droplet and contact transmission must be employed. Further infection control measures include restricting visitors and supervising those in the use of protective equipment. It has also been suggested that the wearing of footwear that can be easily decontaminated should be considered. The removal of linen should be done by staff wearing full protective equipment (goggles, N95 or N100 masks, gloves, disposable gowns/aprons). It is also unfortunate that hospitals were unwittingly involved in amplifying the spread of the epidemic (Tomlinson and Cockram, 2003). Within just 3 weeks of admission of the index case, 156 further cases had been diagnosed, all capable of being traced back to this single case. A case-control study in five Hong Kong hospitals demonstrated that adhering to such precautions as use of a mask, gloves, gowns and hand-washing resulted in no secondary cases in 69 staff who followed these prevention-of-infection measures. When each of the four infection control measures were examined, however, only the wearing of N95 masks was shown to be essential for protection against infection. Unlike most of the other respiratory viruses, however, wearing an N95 mask capable of trapping 95% of all particles adds a further level of protection to staff. When a suspected case enters the hospital, droplet precautions must be strictly enforced, the patient must be isolated to a negative-pressure room and, after transfer to an appropriate facility capable of handling Category 4 pathogens, rapid diagnosis with the least invasive specimen should be attempted. To an individual they are of little consequence, as the illness is short-lived, self-limiting and only in exceptional cases does it lead to any complications. In hospitals, however, when outbreaks occur, almost without exception, ward closure and occasionally the entire closure of the hospital results (Stevenson et al. This is because there is often considerable spread to contacts (staff and patients), resulting in an attack rate of more than 50% (Caul, 1994). Indeed, it is our experience that by the time an outbreak is notified to the virology department, so many staff are absent from work because of illness that this alone results in ward closure. It is known from volunteer studies and outbreak investigations that the incubation period is short, often 1248 h. Indeed, volunteers exposed to infectious virus orally have been found to be shedding virus in faeces only 15 h later (reviewed in Chadwick et al. The illness commences abruptly, with projectile vomiting in over half of cases and profuse watery diarrhoea. However, because the occasional case of vomiting and diarrhoea is not unusual among patients, many of whom are debilitated, elderly or on antibiotics, this may be initially overlooked. Fomite transmission is also possible because of the environmental stability of virus and it has even been suggested, although not actually confirmed, that infection may occur via airborne transmission (Caul, 1994). Although virus shedding in stool is maximal at 2472 h after exposure, virus can be detected for almost 2 weeks in both symptomatic and asymptomatic persons (reviewed in Chadwick et al. Finally, because of the strain diversity among the noroviruses, there is incomplete cross-protection and no long-term immunity.
