Filter by:Patients with failed extubation stay significantly longer in an intensive care unit (ICU) and have a higher mortality rate, than those intubated successfully. Reintubation is associated with life-threatening complications and a poor prognosis. Functional respiratory tests are frequently used as weaning parameters, however, they are not accurate enough to predict extubation failure. The incidence of swallowing dysfunction is underestimated, mainly among patients whose intubation lasts longer than 48 h.We previously observed that the assessment of the swallowing function and oropharyngeal motricity, conducted by the physiotherapist before extubation could be helpful for making decisions to extubate patients intubated for over 6 days. The objective of this study is to validate a scale previously devised and used for physiotherapist bedside evaluation of the swallowing function and oropharyngeal motricity, among patients intubated for over 6 days, to determine whether this scale is a good predictor of airway secretion-related extubation failure.Expected results : to validate a scale previously devised called " physiotherapist evaluation of the swallowing function and oropharyngeal motricity before extubation" by the mean of a multicentric study. In our hypothesis the clinical parameters studied could be predictive of extubation failure. Then, this evaluation could help the medical decision in the choice of the good time for extubation. The final objective is to lower the mortality related to extubation failure.
The data available for the efficacy of AScVS and prazosin is generated through different trials done in different clinical setting. Hence it was felt worthwhile to confirm the documented efficacy of AScVS and prazosin in terms of time taken for clinical recovery in a clinical trial. Along with this, effects of both the therapies on various biochemical parameters will be recorded and compared with. It was also felt necessary to study the effect of combination on the clinical outcome.
This retrospective study was conducted to collect data from approximately 100 patients from 6 months to 18 years of age who were stung by a scorpion but were not treated with antivenom. The study consisted of a review of hospital records of patients who were admitted for intensive care management of scorpion envenomation, at the only two hospitals in North America known to admit children routinely for scorpion sting management without antivenom. The standard of care consisted of symptomatic and supportive care, including airway maintenance, fluid and electrolyte support and, if necessary, sedation.
There is no FDA approved therapy for the treatment of scorpion envenomation, Centruroides scorpion envenomation produces a pattern of neurotoxicity with a spectrum of severity ranging from trivial to life threatening. Patients stung by Centruroides scorpions develop a clinical syndrome which may require sedation with benzodiazepines and observation for 6 to 28 hours of intensive care monitoring. A safe therapy is necessary to halt the progression of symptoms early in the clinical course while avoiding the clinical deterioration that can occur en route to a tertiary facility. Alacramyn® is anticipated to be safer and more effective than the present standard of care, midazolam, and faster-acting such that the need for transport of most rural patients will be eliminated and will reduce hospitalization time. The working hypotheses are as follows: 1. The investigational antivenom is safe as treatment of scorpion sting envenomation. 2. The investigational antivenom is effective as treatment of scorpion sting envenomation.
This treatment protocol will enable therapeutic use of Anascorp in the management of systemic manifestations of scorpion sting envenomation, in patients for whom antivenom would otherwise be unavailable. The working hypotheses are as follows: 1. The investigational antivenom is safe as treatment of scorpion sting envenomation. 2. The investigational antivenom is effective as treatment of scorpion sting envenomation.
This study will examine the risks of workplace exposure to benzene, a substance known to lead to cancer of the blood and possibly of the lungs. It is used widely in industries and is a contaminant in the environment. Researchers from the National Cancer Institute and the China Center for Disease Control (formerly Chinese Academy of Preventive Medicine) had done previous studies of workers in manufacturing industries in China of people who worked at least 1 day from 1972 to 1987 in 12 cities in that country. Data were collected of approximately 75,000 workers exposed to benzene and 35,000 who were not, with the purpose of investigating the relationship between benzene exposure and cancer risk. For workers exposed to benzene, there was a significant risk of cancer affecting the blood cells and a 1.8-fold excess of lung cancer among them. This study will expand those findings and also identify the effects of benzene amounts and whether there is a genetic tendency for benzene poisoning. About 3,860 benzene-exposed workers from the 12 cities will be interviewed. Next-of-kin of deceased workers, and a subcohort (additional grouping) of participants will serve as a control group in the research. Patients who have worked at places where there was exposure to benzene will have a brief physical exam and samples of cells from a mouth rinse and samples from blood will be collected to study the genetic influence on developing blood diseases from workplace exposures. All participants or next-of-kin, for deceased, will be given a questionnaire about their work history, use of cigarettes and hair dyes, medications they take, and family history of cancer. Interviews of about 40 minutes long will be conducted at participants homes or workplaces, at a time convenient to them, and the interviews will be audiotaped.
This randomized trial will investigate important clinical outcomes of patients with acute carbon monoxide poisoning randomized to receive either one or three hyperbaric oxygen treatments.
People who has been in a fire accident have been shown often to be cyanide poisoned as well as poisoned with carbon monoxide(CO). According to recommendations from the Danish Health Agency people who are CO poisoned must be treated with hyperbaric oxygen (HBO). We want to see if HBO treatment can also treat cyanide poisoning. The hypothesis is that as cyanide binds the same place in the mitochondria as CO cyanide will be detached from the mitochondria like CO and diffuse back to the blood.This way it will be easier to treat with hydroxycobalamin.
Lead poisoning remains a common disease among children despite successful public health efforts that reduced its prevalence.Our study was designed to test the hypothesis that lead-poisoning children (BLLs:100-440µg/L) who were given DMSA and multi-nutrients would have a greater fall than children of other groups at 12 weeks of follow-up.
The purpose of this study is to determine whether high doses of pralidoxime(PAM) are effective as compare to lower doses of PAM in the management of moderately sever organophosphorus poisoning patients.
