Objective To analyze the effect of multimodal continuous sciatic nerve block on postoperative analgesia of patients with tibiofibular fracture.
Methods A total of 160 patients with tibiofibular fractures from January 2017 to January 2019 in Tongchuan People′s Hospital in Shaanxi province were selected and randomly divided into two groups, with 80 cases in each group. The control group underwent self-controlled subcutaneous analgesia, and the observation group was given ultrasound-guided multimode continuous sciatic nerve block analgesia. The swelling sensation of leg at 12 hours after operation, the cases with nausea and vomiting within 48 hours after operation, the cases with additional analgesics, the pain of turning over and lying down after operation, and the satisfaction degree to analgesia within 48 hours after operation were observed in both groups.
Results At 12 hours after operation, the degree of leg swelling in the observation group was significantly better than that in the control group (P < 0.05). Eight patients (10.00%) had nausea and vomiting within 48 hours after operation in the observation group, 53 patients (66.25%) had nausea and vomiting in the control group, 3 patients (3.75%) in the observation group and 56 patients (70.00%) were additional morphine analgesics in the control group, and there were significant differences (P < 0.05). At 8, 16 and 32 hours after operation, the VAS scores of turning over and lying down in the observation group were significantly lower than those in the control group (P < 0.05). The satisfaction degree to analgesia in the observation group was significantly better than that in the control group (P < 0.05).
Conclusion Ultrasound-guided multimodal continuous sciatic nerve block is effective in postoperative analgesia of patients with tibiofibular fracture, which can reduce incidence rate of adverse reactions and increase satisfaction degree to analgesia.
