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.
Iliohypogastric/ilioinguinal nerve block is a widely used nerve block technique. It can provide somatic analgesia effect in post-cesarean section.
Epidural analgesia is a traditional analgesia method. Epidural morphine can provide effective analgesia but may cause plenty adverse effect.

morphine consumption
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.
Time frame: 24 hours postoperatively
morphine consumption
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.
Time frame: 6 hours postoperatively
morphine consumption
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.
Time frame: 12 hours postoperatively

Time frame: 48 hours postoperatively
pain score
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.

effective analgesia time
Time period between finish the intervention and the first time parturient use the patient-controlled intravenous analgesia pump for analgesia supplement.

adverse effect
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.
