This investigation evaluated the efficacy of nalbuphine in treating postoperative opioid-induced pruritus (Pr) in pediatric patients. ⋯ La nalbuphine iv à 50 µg·kg(-1) n'est pas efficace pour traiter le prurit postopératoire induit par les opioïdes chez des patients pédiatriques. Le score modifié à l'EAC et la DIPr devront être étudiés plus à fond.

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.

A laboratory investigation was undertaken to compare the in vivo antinociceptive effects of 2% liposomal formulations of prilocaine (PLC), lidocaine (LDC) and mepivacaine (MVC) compared to plain solutions of each of these three local anesthetics. ⋯ These results indicate that liposomes provide effective drug-delivery systems for intermediate-duration local anesthetics. Mepivacaine was affected to the greatest extent, while LDC benefited least from liposome encapsulation, possibly due to greater vasodilatory properties of LDC.
