A comparison of spinal and epidural anesthesia for cesarean section following epidural labor analgesia: A retrospective cohort study.

Introduction: This study aimed to investigate different types of regional anesthesia for cesarean section (CS) following epidural labor analgesia that could lead to various perioperative and postoperative outcomes.

Methods: We retrospectively included those parturients who received epidural labor analgesia but needed subsequent CS under regional anesthesia in our institution from January 2008 to June 2012.

Results: In all, 2341 of 6609 parturients underwent painless labor, and 334 of them converted to CS.
