abstract = {ObjectiveTo compare the analgesic effect and safety of bilateral inferior alveolar nerve block combined with parecoxib sodium analgesia and simple intravenous analgesia pump in analgesia after orthognathic surgery.MethodsForty patients with simple ascending sagittal split osteotomy and ankle plasty were randomly divided into the experimental group and the control group, with 20 patients in each group. The experimental group received 2 mL 1% ropivacaine by inferior alveolar nerve block anesthesia on both sides. Immediately after surgery, parecoxib sodium 40 mg was intravenously administered. The control group was given an intravenous analgesia pump for analgesia. Pain intensity (VAS pain score) and Ramsay sedation score were recorded at 2 h, 4 h, 8 h, 24 h, 48 h after operation, and the incidence of postoperative adverse reactions was observed.ResultsThere was no significant difference in pain intensity and Ramsay sedation score between the two groups at each time point (P > 0.05). During the analgesic treatment, the incidence of nausea and vomiting in the experimental group was significantly lower than that in the control group (P < 0.05).ConclusionBilateral inferior alveolar nerve block combined with parecoxib sodium analgesia and simple intravenous analgesia pump are effective for analgesia after mandibular orthognathic surgery, but the former has a lower incidence of adverse reactions, more suitable for analgesia after mandibular orthognathic surgery.}
