Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical TrialThe haemodynamic effects of propofol and thiopentone for induction of caesarean section.
Forty Chinese women for elective caesarean section received either propofol 2 mg.kg-1 or thiopentone 4 mg.kg-1 for induction of general anaesthesia. Systolic, mean and diastolic arterial pressures and heart rate were recorded non-invasively every minute for ten minutes. Post-induction arterial pressures were similar to pre-induction values with no differences between thiopentone and propofol. ⋯ At caesarean section, induction with propofol causes less variation in arterial pressure than thiopentone. Hypotension is probably prevented by the coincident stimulus of rapid sequence induction. Neonatal Apgar scores were similar between the two groups.

Comparative Study Clinical Trial Controlled Clinical TrialOral premedication in children: a comparison of chloral hydrate, diazepam, alprazolam, midazolam and placebo for day surgery.
A double-blind study consisting of 339 randomly selected children investigated the effects of several premedicants on the preoperative and postoperative behaviour of children who underwent day-stay surgery. Patients were allocated into two groups. Group 1 consisted of 165 children aged between 6 and 47 months. ⋯ No premedicant reduced anxiety in the older group. The time to awaken postoperatively with diazepam was longer than with placebo. Alprazolam and midazolam were unpalatable for children over four years and conferred no advantage over placebo.

Steroids in croup: do they increase the incidence of successful extubation?
Between January 1983 and July 1988, 2623 patients with croup were admitted to the Royal Children's Hospital, Melbourne. A total of 416 patients (16%) were admitted to the Intensive Care Unit and 176 of these patients required intubation. Of these patients 117 patients were successfully extubated at the first attempt and 59 needed reintubation. ⋯ Only one patient who had received steroids failed extubation. Of those who did not receive steroids 59% required reintubation. In patients with croup who fail the first extubation the results of this study suggest that steroids significantly increase the success of subsequent extubations.
