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.

Outcome Measures
Primary Outcomes (1)
The change of numerical rating scale for postoperative pain
At postoperative 6h, 24h, 48h, and 72h.
Secondary Outcomes (1)
The change of postoperative analgesic consumption
At postoperative 6h, 24h, 48h, and 72h.
Study Arms (3)
Epidural (ED) emergent C-sec
Non-ED emergent C-sec
Non-ED elective C-sec
Interventions
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).
Eligibility Criteria
Patients underwent elective or emergent Cesarean section.
You may qualify if:
- Cesarean section(C-sec) under spinal anesthesia
You may not qualify if:
- Patients without accurate medical records
- Failure of epidural analgesia
