Background: To 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. Methods: Forty 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% on both sides. Ropivacaine was treated with inferior alveolar nerve block anesthesia. 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 2h, 4h, 8h, 24h, 48h after operation, and the incidence of postoperative adverse reactions was observed. Results: There 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 (P=0.046) in the experimental group was significantly lower than that in the control group (P<0.05). Conclusion: Bilateral inferior alveolar nerve block combined with parecoxib sodium analgesia and simple intravenous analgesia pump are effective for analgesia after mandibular orthognathic surgery, but the incidence of adverse reactions is significantly lower, more suitable for Analgesia after mandibular orthognathic surgery.
