Trial Outcomes & Findings for Increased Ketorolac Administration After Cesarean Section and Its Effect on Opioid Use: a Randomized Control Trial (NCT NCT03678675)

NCT ID: NCT03678675

Last Updated: 2022-08-18

Results Overview

The amount of MME's will be monitored for each group. MME's will be determined by the amount of opiate mediations administered. The MME value can range from 0 to typically 200 MME's, however there is no upper limit of measureable MME's. The MME's for each patient will be a sum of MME's administered throughout the course of the hospitalization.

Measure
Standard Protocol
Subjects randomized to the standard group will receive the standard postoperative pain protocol that is currently used at Tufts Medical Center. It includes two doses of IV Ketorolac every 6 hours as needed for postoperative pain. Ibuprofen would be ordered 6 hours following the last dose after the last study drug.
Ketorolac Protocol
Subjects randomized to the Ketorolac protocol will receive the study postoperative pain protocol. This includes 6 doses of IV Ketorolac, scheduled every 6 hours. The first dose is administered in the operating room or post-operative care unit. Ketorolac: The intervention is a protocol of scheduled IV Ketorolac administered postoperatively.

SECONDARY outcome

Timeframe: 2 weeks

The patient reported pain scores will be recorded and analyzed for each group. The Pain Score is determined by the patient using a visual analog scale with a range from 0-10, where 0 is no pain at all and 10 is the worst pain imaginable for the patient. Pain scores were collected by postpartum nursing staff per institutional policy. The number of patients with a pain score greater than 3 will be reported. A pain score greater than 3 was chosen as a cutoff as this is the pain score at which an opioid may be indicated for analgesia at our institution.

SECONDARY outcome

Timeframe: Inpatient pain control satisfaction as reported at two weeks postpartum

Population: 52 patients in the standard protocol and 52 patients in the ketorolac group responded to the 2 week postpartum survey.

Two weeks after cesarean section, subjects were contacted by telephone to complete a survey on postpartum pain management. At least three attempts were made to contact subjects by telephone. In the follow-up phone call, patients were asked to rate their satisfaction with their postpartum care: very satisfied, satisfied, neutral, dissatisfied, or very dissatisfied. The number below describes the number of patients who reported they were "very satisfied" with their care.
