Randomized Controlled Trial Comparative Study Clinical Trial
Subhypnotic propofol does not treat postoperative vomiting in children after adenotonsillectomy.
To investigate the efficacy of a subhypnotic dose of propofol to treat vomiting in children after adenotonsillectomy. ⋯ We conclude that an intravenous bolus of 0.2 mg.kg-1 propofolis not effective in the treatment of postoperative vomiting in children after adenotonsillectomy when a standardized anaesthetic with thiopentone, halothane, nitrous oxide, and 1.5 mg.kg-1 codeine phosphate is used, but it does cause sedation and pain on injection.

Randomized Controlled Trial Clinical Trial
Bupivacaine decreases epidural meperidine requirements after abdominal surgery.
The purpose of this study was to determine the optimal of three concentrations of bupivacaine (0.0%, 0.05%, 0.10%) to add to an epidural infusion of meperidine (1 mg.ml-1) for postoperative pain relief. ⋯ Although analgesia was identical among groups, the lower serum concentrations of meperidine support the addition of bupivacaine 0.10% to meperidine when administered as a continuous infusion following abdominal surgery.

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.
