Comparison of Postoperative Opioid Consumption and Pain Scores in Primary Versus Repeat Cesarean Delivery in Opioid Naïve Patients.

Abstract：

BACKGROUND:Cesarean deliveries represent a large percentage of deliveries worldwide. Patients undergoing repeat cesarean deliveries are known to have increased risks for surgical complications. However, little is known regarding potential differences in pain. We sought to compare postoperative opioid consumption and pain scores in opioid naïve patients undergoing primary versus repeat non-emergent cesarean delivery. METHODS:This was a retrospective cohort study. Patient inclusion criteria included: having a non-emergent cesarean delivery, receiving a spinal procedure for surgical anesthesia without general anesthesia, and following the same postoperative pain management protocols. Exclusion criteria included: history of opioid tolerance, illicit drug use, or prior, non-obstetric, major abdominal surgery. The primary outcome marker was total morphine equivalents consumed 0-72 h post-procedure compared between the primary versus repeat cesarean delivery groups. Secondary outcome markers were opioid consumption and pain scores in 24-h period increments for the first 72 h postoperatively. RESULTS:1617 patients were screened. 217 primary and 377 repeat cesarean deliveries met criteria for comparison. Reduced opioid consumption was demonstrated for the total opioid consumption 0-72 h for the repeat cesarean delivery group (median = 35) compared to the primary cesarean delivery group (median = 58), p = 0.0005. When divided into 24-h periods, differences were demonstrated for the 24-48 and 48-72 h periods but not the 0-24 h period. Pain scores did not differ statistically. CONCLUSION:Opioid naïve obstetric patients who undergo non-emergent repeat cesarean delivery demonstrate lower opioid consumption in the postoperative period. Providers should be aware of this potential difference in order to better educate patients and provide adequate pain management. HIGHLIGHTS:The study reviewed differences in opioid consumption between primary and repeat cesarean deliveries. All patients received the same protocol for spinal dosage and pain management. Repeat cesarean deliveries were associated with lower opioid consumption.
