Sedation and analgesia use in tumor ablation is a necessary part of the procedure. However, the optimal medicine for sedation and analgesia for tumor ablation remains controversial. Currently, morphine is a traditional opioid used for pain control and anaesthesia. As no publications have compared the anaesthetic and analgesic effects between nalbuphine and morphine during tumor ablation, this trial aims to compare the analgesic efficacy and safety of nalbuphine and morphine for perioperative tumor ablation. In addition, other endpoints in term of perioperative analgesia indexes, such as ablation time, daily dose, analgesia satisfaction, quality of life, and safety, etc. will be compared.
This randomized, positive control, multicentre trial is designed to compare the analgesic efficacy and safety of nalbuphine hydrochloride injection and morphine hydrochloride injection for perioperative tumor ablation.
