BACKGROUND The combination of propofol and alfentanil with nitrous oxide provides balanced anesthesia with rapid recovery and minimal emetic side effects. The object of this study was to compare recovery parameters at varying proportions of propofol and alfentanil, and to determine the dosing rate and plasma concentration of propofol necessary to supplement nitrous oxide in the presence of vary...

A vacuole-formation substance, cereulide of Bacillus cereus, is an emetic toxin in animals. Both oral administration and intraperitoneal injection of cereulide caused dose-dependent emesis in Suncus murinus, a new animal model of emesis. Vagotomy or a 5-HT3 receptor antagonist completely abolished this emetic effect. Therefore, cereulide causes emesis through the 5-HT3 receptor and stimulation ...

Shiwa Puhshad Singh, a Rajpoot, aged about 4o, was admitted into the hospital oil the 19th of March, 1870, with the usual symptoms of apoplexy?coma, deep stertorous breathing, pupils firmly contracted, pulse 120, strong full and throbbing, face bloated, indicative of kidney disease?old marks of cupping in the lumbar regions. He had evidently been drinking rather hard the previous day, and the a...

Bacillus cereus is a well-known cause of food-borne illness, but infection with this organism is not commonly reported because of its usually mild symptoms. A fatal case due to liver failure after the consumption of pasta salad is described and demonstrates the possible severity of the emetic syndrome.

The emetic responses induced by staphylococcal enterotoxin A (SEA), SEB, SEC2, SED, SEE, SEG, SEH, and SEI in the house musk shrew (Suncus murinus) were investigated. SEA, SEE, and SEI showed higher emetic activity in the house musk shrew than the other SEs. SEB, SEC2, SED, SEG, and SEH also induced emetic responses in this animal model but relatively high doses were required. The house musk sh...

PURPOSE To synthesize the available randomized evidence on the efficacy of dexamethasone when used for protection against acute and delayed nausea and vomiting in patients receiving highly or moderately emetogenic cancer chemotherapy. MATERIALS AND METHODS A meta-analysis was performed using trials identified through MEDLINE (1966 to April 1999), Embase, Derwent Drug File, and the Cochrane Li...

Chemotherapy-induced nausea and vomiting (CINV) is still a common and debilitating side effect despite recent advances in its prevention and treatment. The intrinsic emetogenicity of chemotherapy agents allowed grouping into four risk groups (high, moderate, low, and minimal risk of emetogenicity). The prevention of acute and delayed CINV for intravenous agents and one day regimens is well stud...

The first symptom was vomiting about fifteen minutes after the taking of the emetic. Both the boys vomited almost simultaneously. They vomited without any nausea. The vomiting continued almost every 3 or 4 minutes for an hour and half. They first brought up food and afterwards a thin gelatinous substance. Simultaneously with the 6th vomiting the elder one began to pass thin dirty white stools. ...

Patients with severe gag reflex (SGR) have difficulty getting the treatment they require in local clinics, and many tend to postpone the start of their treatment. To address this problem, dentists have used behavioral techniques and/or pharmacological techniques for treatment. Among the pharmacological methods available, propofol IV sedation is preferred over general anesthesia because it is a ...
