Preoperative Epidural Labor Analgesia and Postoperative Pain

The Influence of Preoperative Epidural Labor Analgesia on Postoperative Pain in Parturients Undergoing Cesarean Section: a Retrospective Analysis

Parturients who undergo emergency Cesarean section (C-sec) after experiencing labor pain are likely to develop pain-induced central sensitization. The investigators hypothesized that those without epidural labor analgesia undergoing subsequent emergency C-sec would experience more severe postoperative pain or require more analgesia after C-sec compared to those with epidural labor analgesia. Thus, the investigators conducted this retrospective study by grouping parturients undergoing emergency C-sec after experiencing labor pain into two groups (epidural labor group and no epidural labor group) and those undergoing elective C-sec aimed to compare the effect of epidural labor analgesia on postoperative pain severity and analgesic consumption.

Inclusion Criteria:

• Cesarean section(C-sec) under spinal anesthesia

Exclusion Criteria:

• Patients without accurate medical records
• Failure of epidural analgesia
