Cesarean Section, Iliohypogastric/Ilioinguinal Nerve Block, Quadratus Lumborum Block
Conditions
Brief summary
The purpose of this study is to compare the analgesic effect of ultrasound-guided quadratus lumborum block and iliohypogastric/ilioinguinal nerve block for postoperative pain management in patients undergoing cesarean section.
Interventions
PROCEDUREquadratus lumborum block
Quadratus lumborum block is an effective nerve block method in post-cesarean section analgesia. It is a relatively new technique that may provide analgesic effect in somatic pain and visceral pain, but has not been verified yet.
PROCEDUREiliohypogastric/ilioinguinal nerve block
Iliohypogastric/ilioinguinal nerve block is a widely used nerve block technique. It can provide somatic analgesia effect in post-cesarean section.
PROCEDUREepidural analgesia
Epidural analgesia is a traditional analgesia method. Epidural morphine can provide effective analgesia but may cause plenty adverse effect.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| morphine consumption | 24 hours postoperatively | Every parturient use a patient-controlled intravenous analgesia pump as supplement for the interventions. The analgesia pump contains morphine and can record morphine consumption. Postoperative use of morphine can reflect analgesic effect. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| hospitalize cost | at discharge assessed up to 10 days | Total cost in this hospitalization |
| effective analgesia time | 48 hours postoperatively | Time period between finish the intervention and the first time parturient use the patient-controlled intravenous analgesia pump for analgesia supplement. |
| morphine consumption | 6 hours postoperatively | Every parturient use a patient-controlled intravenous analgesia pump as supplement for the interventions. The analgesia pump contains morphine and can record morphine consumption. Postoperative use of morphine can reflect analgesic effect. |
| hospital stay | at discharge assessed up to 10 days | The hospitalize length |
| adverse effect | 6 hours postoperatively | Nausea and vomiting, pruritus, oversedation, respiratory depression and urinary retention are considered adverse effects. The incidence and severity are recorded, 1 score refers to mild, 2 scores refers to moderate, 3 scores refers to severe and treatment needed. |
| satisfaction score | 48 hours postoperatively | Ask the patient to evaluate satisfaction score using 0-10. 0 refers totally dissatisfied, 10 refers to the most satisfied |
| pain score | 6 hours postoperatively | Use visual analogue scale (VAS) 0-10 to evaluate pain intensity and reflect analgesic effect. 0 refers to completely no pain, 10 refers to the most severe pain she has experienced. |
