SAN FRANCISCO – Administration of intravenous ketorolac was associated with a reduction in postoperative pain in patients undergoing orbital surgery, according to findings from a study presented at the 2019 American Academy of Ophthalmology Meeting in San Francisco, CA.

Study patients received intravenous ketorolac (n=50) or acted as controls (n=50) (both the patients and surgeon were blinded). The primary outcome measures were postoperative pain scores (measured on a scale of 0 to 10), bleeding complications, and need for postoperative antiemetic and opioid analgesics; these outcomes were measured immediately after surgery and on postoperative Day 1.

Results showed that pain scores immediately after surgery and on postoperative Day 1 were 3.08 and 1.04 for the intravenous ketorolac group vs 5.44 and 2.66 for the control group, respectively (both: P=.001). Moreover, a smaller percentage of patients in the intravenous ketorolac group required antiemetics (12% vs 22%) or opioids (8% vs 24%; P=.03), when compared with controls. In addition, neither group experienced bleeding complications.

Based on their findings, the researchers concluded that “[intravenous ketorolac] reduces postoperative pain in orbital surgery and the requirement for opioid analgesics, without increasing the risk of bleeding complications.”
