AbstractObjective: To determine the effectiveness of extending epidural analgesia following epidural labor analgesia for intrapartum cesarean section, and provide a reference for clinical practice.Methods: Data of 1254 singleton parturient who failed trial of epidural labor analgesia and underwent intrapartum cesarean section were retrospectively included. After entering the operating room, parturient were given 3 ml of 1.5% lidocaine with 1:200,000 epinephrine 15 µg as a test dose, followed by a dose of 10 ml 0.75% ropivacaine plus 5 ml of 2% lidocaine mixed solution was administered via the epidural catheter. Case data were reviewed and analyzed of cesarean section anesthesia implementation methods, results and maternal and neonatal outcomes.Results: Of the 1254 parturient, 4.7% (59 of 1254) underwent general anesthesia directly, 7.1% (89 of 1254) were given combined spinal and epidural anesthesia, and the other 88.2% (1106 of 1254) underwent extending epidural anesthesia, 3.5% (39 of 1106) of them were given general anesthesia after extending epidural anesthesia failed, and 96.5% (1067 of 1106) parturient have a successful extending epidural anesthesia. Adverse reactions of extending epidural anesthesia: 6.7% (72 of 1067) parturient experienced hypotension and 12.1% (129 of 1067) of nausea and vomiting occurred. For the neonatal Apgar scores at 1 min, eleven of 1254 (0.9%) newborns were between 0 and 3 points, 107 (8.5%) newborns between 4 and 7 points, and 1136 (90.6%) newborns Apgar scores between 8 and 10 point. 24 (1.9%) newborns with Apgar scores between 4 to 7 points at 5 min transferred to the department of neonatology, and the rest 1230 (98.1%) newborns with Apgar scores 8-10 points.Conclusion: Extending epidural analgesia using the well-functioning epidural catheter for epidural labor analgesia might be a reliable and effective anesthetic method for intrapartum cesarean section.
