Reprint of: Efficacy and safety of different doses of dezocine for preemptive analgesia in gynecological laparoscopic surgeries: A prospective, double blind and randomized controlled clinical trial

The analgesia and sedation effects of dezocine were enhanced with the increase of usage dose, which suggested that the effects of dezocine were dose-dependent. Intravenous injection of 0.15 mg/kg dezocine 15 min before gynecological laparoscopic surgery showed better analgesic and sedative effects as well as less adverse reactions, and should be the appropriate dose to be used in the preemptive analgesia in gynecological laparoscopic surgeries.
