Application of Hydromorphone and Ropivacaine in Ultrasound-Guided Brachial Plexus Block of Children

This research was designed to investigate the effects of hydromorphone combined with ropivacaine anesthesia on brachial plexus block of upper limbs in children.This was a randomized prospective study.A total of 120 children with upper limb fractures were included in this study and treated wtih open reduction and internal fixation (ORIF). The children were randomized into control group and research group. All of them were given a brachial plexus block and anesthetics (control group: 0.2% ropivacaine; research group: additional 5 μg/kg hydromorphone.The time of onset and exercise recovery of the research group increased, and the use times of analgesic drugs decreased, which were significantly different from those of the control group (all P<.05).Hydromorphone can enhance the effectiveness of ropivacaine in blocking the brachial plexus and reduce postoperative pain and the demand for analgesics. Strong postoperative sedation can improve sleep quality and nursing satisfaction.
