Introduction  While uncommon for cesarean delivery, general anesthesia may be patient requested or necessary due to maternal contraindication. Traditionally, opioids are used as a part of the general anesthetic. Because of their associated complications, it is standard to limit opioid use and fetal narcotic exposure during cesarean delivery. We conducted a retrospective study to evaluate the feasibility of multi-modal opioid-free general anesthesia for cesarean delivery.  Methods  Electronic medical records were obtained for patients receiving general anesthesia for cesarean delivery of live pregnancies through 2017 at our tertiary care facility. Post-operative pain was estimated using a 10-cm visual analogue scale and by calculating postoperative narcotic requirements in milligram morphine equivalents (MME) over three-time periods: during post-anesthesia recovery in the post-anesthesia care unit (PACU), the first 24 hrs after PACU discharge, and 24-48 hrs after PACU discharge. Apgar scores were also obtained to quantify neonatal effects of the general anesthetic.  Results  Eight of 17 patients (47.06%) received opioid-free anesthesia (OFA), and nine of 17 patients (52.94%) received anesthesia with opioids (OA). No significant difference was found between groups in terms of postoperative mean Visual Analog Scale (VAS) pain score over each time period. Similarly, no significant difference was found between groups in terms of postoperative narcotics requirement at all study points. Apgar scores were not significantly different between the two groups.  Conclusion  The OFA group displayed equivalent analgesia to the OA group in terms of self-reported VAS pain scores and postoperative MME. A larger prospective study is recommended to fully evaluate OFA for cesarean delivery.
