However, little is known about the surgical times in the operating room and a choice of anesthesia for cesarean deliveries. Objective: This study was designed to compare times from the arrival to the OR to the delivery of the fetus between regional and general anesthesia along with maternal and fetal outcomes, for patients undergoing cesarean sections for non-reassuring fetal tracing. Study Design: Records were reviewed for patients who underwent cesarean delivery for non-reassuring fetal heart rate tracing from February 2012 to May 2018. A total of 190 charts were selected. Seven patients who received epidural or spinal anesthesia and then converted to general anesthesia (GA) were excluded. The primary outcomes were: 1) entering the operating room to skin incision (min);2) the time from entering the operating room to delivery of the fetus (min). These times were compared among the patients who underwent epidural, spinal and general anesthesia. The secondary criteria included time from skin incision to delivery of the fetus (min), estimated blood loss (ml), Apgars scores, Arterial/venous cord pH, NICU admissions and fetal complications. ANOVA or Kruskal-Wallis Test was used for the continuous variable and Fisher’s exact test was used for the categorical variable to test the differences between groups. Logistic regression model was used for the binary outcomes after adjusting for age, BMI and number of prior laparotomies. Results: Infants in the GA group were delivered significantly faster when compared to epidural and spinal group separately with a P-value of 0.001. The mean time from arrival to OR to delivery of the newborn in GA group was 12.7 minutes, compared to 27 minutes in epidural group and 32.7 minutes in the spinal group. Time intervals from time in the OR to incision and time from incision to delivery of the fetus were also calculated and were significantly shorter in the GA group when compared to spinal and epidural groups, P Conclusion: The induction of general anesthesia for emergency cesarean section resulted in shorter times to delivery compared to spinal and epidural. General anesthesia was associated with lower, albeit not statistically significant Apgar scores and higher NICU admissions, and had similar cord gases compared to neuraxial anesthesia group.展开更多
