Preoperative Intravenous Ketorolac Safely Reduces Postoperative Pain in Levator Advancement Surgery Purpose: To assess the impact of intravenous ketorolac (IVK) on self-reported pain scores, requirements for opioid analgesic and anti-emetic medications, and bleeding complications in the setting of levator advancement surgery Methods: A prospective randomized controlled trial was performed among adult patients undergoing levator advancement surgery. Pain scores were measured immediately after surgery, prior to discharge from the surgical facility, and on the first postoperative day. The requirements for postoperative analgesic and anti-emetic medications were recorded. Statistical comparisons were performed via a dedicated computerized software package. Results: Fifty patients (20 males, 30 females, mean age = 65.7 years, standard deviation = 11.9 years) underwent levator advancement without IVK and acted as controls. An additional 50 patients received IVK (19 males, 31 females, mean age = 64.6 years, standard deviation = 12.0 years). As compared with control patients, IVK resulted in statistically significant reductions in pain score immediately after surgery (4.62 vs. 1.44, p = 0.0001) and on postoperative day 1 (3.22 vs. 1.24, p = 0.0001). Fourteen patients (28%) in the control and 4 patients (8%) in the group that received IVK required opioid analgesics (p = 0.017). Seven patients (14%) in the control group and 1 patient in the group that received IVK required anti-emetic medications (p = 0.059). No patient experienced a hemorrhagic complication. Conclusions: In the setting of levator advancement surgery, IVK results in a dramatic reduction in self-reported pain score immediately after surgery and on postoperative day 1 and the requirement for opioid analgesics. This medication may be safely utilized for ptosis repair.
