Randomized Controlled Trial Comparative Study
Intraabdominal local anaesthetics for postoperative pain relief following abdominal hysterectomy: a randomized, double-blind, dose-finding study.
Local anaesthetics administered intraabdominally have been found to reduce analgesic requirements postoperatively after hysterectomy. This study was designed to assess the optimal dose of local anaesthetics for best pain relief. ⋯ Satisfactory analgesia can be achieved with low doses of levobupivacaine administered intraabdominally, except during the early postoperative period. No advantages were seen in this study when higher doses of levobupivacaine were administered as a continuous infusion for postoperative pain relief.
