ABSTRACT:Objective: To investigate the efficacy of intraoperative local injection of dexamethasone combined with ropivacaine in preventing complications associated with incision of calcaneal fracture. Methods: A retrospective study was conducted in 136 patients with calcaneal fractures who underwent surgery for calcaneal fractures admitted to our hospital from January 2019 to October 2022, all of whom underwent lateral foot enlargement incision reduction irregular plate internal fixation, 68 cases of 68 cases were injected with dexamethasone combined with ropivacaine around the intraoperative incision (observation group), and 68 cases of 69 feet underwent conventional treatment (control group). There was no significant difference in the preoperative general data between the two groups (p>0.05). The two groups of patients were compared with incision pain, foot swelling, incision exudation, incision flap necrosis, and incision infection within one week after surgery. Results: The incision pain score, foot swelling and incision exudation in group A were better than those in group B. Conclusion: Local injection of dexamethasone combined with ropika around the intraoperative incision can effectively reduce postoperative pain and reduce incision-related complications in patients with calcaneal fracture.
