Abstract

It is unclear why some patients experience pain during cesarean delivery despite receiving appropriate regional anesthesia. Our primary aim was to determine what demographic and clinical variables predict intraoperative pain during cesarean delivery with neuraxial anesthesia. From July 2019 through March 2020, we administered a previously validated patient satisfaction survey to parturients who had a cesarean delivery under regional anesthesia for nonemergent obstetric indications. We performed a post hoc analysis restricted to subjects who had single injection spinal and combined spinal-epidural anesthesia. Parturients who did and did not report pain differed in height, intrathecal hyperbaric bupivacaine dose, and the time from incision to wound closure. We performed an ordinal logistic regression analysis on the 168 subjects with complete data using the aforementioned variables along with the time of day of cesarean delivery. Incision to wound closure time (P < 0.01) predicted intraoperative pain. The multivariate logistic regression model was statistically significant (P < 0.01) and had a receiver operator curve value of 0.74. The duration of time from incision to wound closure predicted intraoperative pain during cesarean delivery under regional anesthesia.
