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 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.

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.
