Anaesthesia
-
This apparatus was seen by one of us (DAW) in a private collection. Although it was one of the first ether inhalers to be manufactured commercially, and was described in the medical literature of the time, it is not mentioned in any of the histories of anaesthesia. Its genesis was unusual, and it presents a number of interesting features, not least being the purpose for which it was originally designed.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of cyclizine, ondansetron and placebo as prophylaxis against postoperative nausea and vomiting in children.
Nausea and vomiting is a relevant and common problem with unfavourable sequelae in children undergoing some plastic surgery procedures. There is a lack of anti-emetic trials performed in children, with only a few investigating the roles of the older anti-emetic agents such as cyclizine compared with newer ones such as ondansetron. ⋯ Postoperative vomiting was significantly reduced with ondansetron prophylaxis (p = 0.006) but there was no detectable anti-emetic effect with cyclizine. Furthermore, cyclizine caused pain on injection (p < 0.001).

Randomized Controlled Trial Clinical Trial
Effect of milrinone on vecuronium-induced neuromuscular block.
We examined the effect of milrinone, a phosphodiesterase III inhibitor, on neuromuscular block induced by vecuronium. Thirty adult patients were randomly assigned to one of two equal groups: the milrinone group and the control group. Subjects in the milrinone group received an intravenous loading dose of milrinone 5 microg x kg-1x min-1 for 10 min, followed by an infusion at a rate of 0.5 microg x kg-1x min-1. ⋯ The onset of neuromuscular block in the milrinone group was significantly slower than in the control group. The times to the returns of the four twitches of the train-of-four, times to recovery of the ratio of the first twitch to the control twitch to 25% and 50%, and the times to the recovery of the train-of-four ratio to 25% and 50% were significantly shorter in the milrinone group than in the control group. We conclude that milrinone delays the onset of neuromuscular blockade but hastens its recovery in anaesthetised patients receiving vecuronium.
