Abstract

Objective: To determine the efficacy of preoperative gabapentin on patient-reported pain levels and postoperative opioid requirements following sinonasal surgery. Study Design: Retrospective review. Setting: Academic institution. Methods: Patients undergoing sinonasal surgery between July 2019 and January 2020 were followed. Groups were divided into those that received 600 mg of oral gabapentin 1 hour preoperatively (gabapentin) and those that did not (control). Postoperatively, each patient was counseled to use acetaminophen, ibuprofen, and oxycodone as needed for pain control. Patients completed a daily postoperative pain and medication log. Pain was measured by the visual analog scale (VAS) and opioid use by morphine equivalent dose (MED). Chi-square test and Wilcoxon test were used for data analysis. Results: Fifty-seven patients were included (control, n = 28; gabapentin, n = 29). There was no significant difference in age, sex, or baseline Sinonasal Outcome Test–22 scores between the groups. The total MED, postoperative day (POD) 1-2 MED, POD 3-4 MED, and POD 5-6 MED did not differ significantly between the control (17.9, 12.2, 4.6, 1.5) and gabapentin (19.0, 8.9, 7.2, 3.5) groups (P =.98,.25,.16,.44). The mean daily VAS score did not differ significantly between the control (3.1) and gabapentin (2.8) groups (P =.81). The mean daily VAS score decreased significantly in both groups with each successive POD (P =.004). Conclusion: Preoperative gabapentin did not significantly reduce postoperative pain or opioid use. Postoperative discomfort following sinonasal surgery is mild, and opioid intake is minimal.
