Related Conditions & MeSH terms

• Cesarean Section

• Pain, Postoperative
• Quadratus Lumborum Block

Intervention

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

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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.	24 hours postoperatively
Secondary	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.	6 hours postoperatively
Secondary	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.	12 hours postoperatively
Secondary	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.	48 hours postoperatively
Secondary	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.	6 hours postoperatively
Secondary	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.	12 hours postoperatively
Secondary	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.	24 hours postoperatively
Secondary	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.	48 hours postoperatively
Secondary	effective analgesia time	Time period between finish the intervention and the first time parturient use the patient-controlled intravenous analgesia pump for analgesia supplement.	48 hours postoperatively
Secondary	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.	6 hours postoperatively
Secondary	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.	12 hours postoperatively
Secondary	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.	24 hours postoperatively
Secondary	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.	48 hours postoperatively
Secondary	satisfaction score	Ask the patient to evaluate satisfaction score using 0-10. 0 refers totally dissatisfied, 10 refers to the most satisfied	48 hours postoperatively
Secondary	hospital stay	The hospitalize length	at discharge assessed up to 10 days
Secondary	hospitalize cost	Total cost in this hospitalization	at discharge assessed up to 10 days
