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)
