About

The purpose of this study is to investigate the effect of different kinds of popular peripheral nerve blocks for postoperative analgesia after cesarean delivery is completed, compared with traditional epidual analgesia.

Full description

Visual Analogue Scale (VAS) and morphine consumption was adopted to evaluate the pain relief.

102 participants in 4 patient groups

QLB type 2
Experimental group
Description:
Ultrasound-guided, Inject at the point posterior to quadratus lumborum muscle, 0.2% ropivacaine 30mL in each side for a total of 60mL. Subjects also receive an intravenous patient controlled analgesia (PCA) pump of 0.5 mg/mL morphine for 48 hours.
Treatment:
Procedure: QLB
Procedure: Intravenous patient controlled analgesia (PCA)
QLB type 3
Experimental group
Description:
Ultrasound-guided, Inject at the point between the quadratus lumborum and the psoas major muscle, 0.2% ropivacaine 30mL in each side for a total of 60mL. Subjects also receive an intravenous patient controlled analgesia (PCA) pump of 0.5 mg/mL morphine for 48 hours.
Treatment:
Procedure: QLB
Procedure: Intravenous patient controlled analgesia (PCA)
QLB type 2+3
Experimental group
Description:
Ultrasound-guided, conduct both QLB type 2 and 3, 0.2% ropivacaine 15mL in each point of injection, for a total of 60mL. Subjects also receive an intravenous patient controlled analgesia (PCA) pump of 0.5 mg/mL morphine for 48 hours.
Treatment:
Procedure: QLB
Procedure: Intravenous patient controlled analgesia (PCA)
epidural anesthesia group (EA)
Active Comparator group
Description:
Epidural catheter placement was conducted when finishing spinal anesthesia. After surgery, 30 mL saline (placebo) was Injected at the point posterior to the quadratus lumborum in each side for a total of 60mL. We used a single bolus of 0.15% ropivacaine + 2 mg morphine (diluted in 6 ml saline) via epidural cathether. Subjects also receive an intravenous patient controlled analgesia (PCA) pump of 0.5 mg/mL morphine for 48 hours.
Treatment:
Procedure: QLB
Procedure: Intravenous patient controlled analgesia (PCA)
