Randomized Controlled Trial Multicenter Study
Intravenous nalbuphine 50 microg x kg(-1) is ineffective for opioid-induced pruritus in pediatrics.
This investigation evaluated the efficacy of nalbuphine in treating postoperative opioid-induced pruritus (Pr) in pediatric patients. ⋯ This preliminary report suggests that nalbuphine 50 microg x kg(-1) iv is not effective in treating postoperative opioid-induced pruritus in pediatric patients. The modified CAS score and PrID warrant further investigation.

Presently, no standardized technique exists to monitor injection pressures during peripheral nerve blocks. Our objective was to determine if a compressed air injection technique, using an in vitro model based on Boyle's law and typical regional anesthesia equipment, could consistently maintain injection pressures below a 1293 mmHg level associated with clinically significant nerve injury. ⋯ En créant et en maintenant dans la seringue une compression d'air à 50% ou moins, les pressions d'injection seront dans l'ensemble sous le seuil des 1293 mmHg associé à un facteur de risque de lésion nerveuse cliniquement significative. Cette technique peut permettre une surveillance simple, objective et en temps réel pendant les injections d'anesthésiques locaux tout en réduisant fondamentalement la vitesse d'injection.

Randomized Controlled Trial
Topical lidocaine and oral acetaminophen provide similar analgesia for myringotomy and tube placement in children.
Preoperative oral acetaminophen (30 mg x kg(-1)) was compared with topical 2% lidocaine ear drops for postoperative analgesia following bilateral myringotomy and tube placement (BMT) in children. ⋯ Topical lidocaine and oral acetaminophen in a dose of 30 mg x kg(-1) provide similar analgesia following BMT.

A survey was undertaken at a single Academic Health Sciences Centre to document the opinions of anesthesiologists regarding what variables are important to document on the anesthetic record. A subsequent chart review of anesthetic records was undertaken to determine the extent to which these anesthesiologists record the variables they consider important. ⋯ Les anesthésiologistes de McGill considèrent que de nombreuses variables préopératoires et peropératoires sont importantes à noter au dossier anesthésique. Une revue subséquente des dossiers a indiqué que beaucoup de ces variables ne sont pas constamment inscrites. La transmission des informations médicales liées à l'anesthésie serait améliorée si les anesthésiologistes notaient plus régulièrement les variables qu'ils jugent les plus importantes.

Propofol neurotoxicity has been demonstrated in several cell culture systems. This study was undertaken to determine whether propofol has neurotoxic effects on peripheral, retinal, and autonomic neurons, and which neurons are particularly liable to injury by propofol. ⋯ While the clinical safety profile of propofol has been well documented, at high concentrations propofol has potential neurotoxicity on growing neurons in vitro.
