Prospective Effect of Intravenous Ketorolac on Opioid Use, EBL and Complications Following Cesarean Delivery

Summary

In this randomized, double-blind control trial to evaluate the effect of ketorolac given at the time of cord clamp has on estimated blood loss and postcesarean pain control. Patients will be randomized to either placebo or ketorolac prior to surgery. Those randomized to ketorolac will receive ketorolac at cord clamp and three additional doses every 6 hours (total 4 doses/24 hours). Those in the placebo group will receive normal saline during those time periods. Our primary outcome is to assess whether intra-operative ketorolac increases the estimated blood loss during Cesarean delivery.
