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.

Epidural catheter was inserted for labor analgesia using an 18-gauge Tuohy needle and a 20 gauge epidural catheter. In our institute, for epidural labor analgesia, 10 ml bolus of 0.075% levobupivacaine mixed with fentanyl 2 μg/ml was administered and same regimen was continuously infused by patient-controlled epidural analgesia (infusion rate : 10 ml/hr, bolus : 4 ml, lockout time: 30 min).
