Cesarean Section
Conditions
Brief summary
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.
Interventions
PROCEDUREEpidural labor analgesia
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).
