Randomized Controlled Trial Comparative Study Clinical Trial
Granisetron reduces the incidence and severity of nausea and vomiting after laparoscopic cholecystectomy.
Postoperative nausea and vomiting (PONV) are commonly observed undesirable consequences of laparoscopic cholecystectomy. This study was undertaken to compare granisetron, a selective 5-hydroxytryptamine type 3 receptor antagonist, with droperidol for reducing the incidence and severity of PONV after laparoscopic cholecystectomy. ⋯ Granisetron is more effective than droperidol and placebo for reducing the incidence and severity of PONV after laparoscopic cholecystectomy.

To review the literature on airway and respiratory management following non-lethal (suicidal) hanging and to describe the anatomy, injury and pathophysiological sequelae and their impact on patient care. ⋯ Airway injuries severe enough to interfere with airway management are uncommon after attempted suicide by hanging. Irrespective of the initial neurological assessment, aggressive and early resuscitation to optimize cerebral oxygenation is recommended.

Comparative Study
Comparison of distal oesophageal temperature with "deep" and tracheal temperatures.
To compare distal oesophageal (reference) temperature with "deep-sternal," "deep-forehead," and tracheal temperatures, establishing the accuracy and precision of each. ⋯ Our data suggest that tracheal temperatures may not be an adequate substitute for conventional core-temperature monitoring sites. In contrast, the accuracy and precision of deep-tissue temperature monitoring at the sternum and forehead was sufficient for clinical use.

Although cricoid pressure (CP) is a superficially simple and appropriate mechanical method to protect the patient from regurgitation and gastric insufflation, in practice it is a complex manoeuvre which is difficult to perform optimally. The purpose of this review is to examine and evaluate studies on the application of (CP). It deals with anatomical and physiological considerations, techniques employed, safety and efficacy issues and the impact of CP on airway management with special mention of the laryngeal mask airway. SOURCE OF MATERIAL: Three medical databases (48 Hours, Medline, and Reference Manager Update) were searched for citations containing key words, subject headings and text entries on CP to October 1996. ⋯ If CP is to remain standard practice during induction of anaesthesia, it must be shown to be safe and effective. Meanwhile, further understanding of its advantages and limitations, improved training in its use, and guidelines on optimal force and method of application should lead to better patient care.

Comparative Study
An analysis of review articles published in four anaesthesia journals.
To see if the authors of review articles in anaesthesia journals are making use of systematic methods in their preparation. ⋯ There is little evidence that reviews currently accepted for publication in anaesthesia journals have been prepared systematically.
