We investigate the claim that administering ketorolac (Toradol) increases bleeding and should be avoided in surgeries for which there is concern for bleeding.

Claim 1. Administration of intraoperative ketorolac increases the bleeding time due to platelet inhibition

Claim 2. Increased bleeding time translates to higher rate of surgical bleeding

Claim 3. The magnitude of bleeding propensity attributable to ketorolac is clinically relevant

Our guest today is Dr. Jamie Sparling of the Critical Care Division of the Massachusetts General Hospital.
