Effect of long-acting local anesthetic infiltration in surgical wound for post operative pain control in Zygomaticomaxillary complex fracture

Abstract

to compare the analgesic efficacy of Bupivacaine 0.5% wound infiltration with placebo incisional infiltration in relieving postoperative pain for first twenty-four hours. Methods: this study was performed on sixty patients, of both sexes , with varied age groups. Patients underwent open reduction Internal fixation of Zygomaticomaxillary complex fractures, confined to ASA category I-II. Patients were selected by convenience sampling and were divided into two groups i.e. Group I and group II. Group I comprised of thirty patients and were infiltrated with bupivacaine 0.5% at wound margins postoperatively. Group II also comprised of thirty patients and were infiltrated with saline at wound margins postoperatively. Results: The postoperative pain scores in both groups were low and there were no significant difference between the groups in pain scores (p=0.07) and Analgesic consumption (p=0.11). Conclusion: wound infiltration with Bupivacaine 0.5% has not been shown to provide additional analgesic or outcome benefit in the setting of a comprehensive multimodal analgesic approach.
