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.
