---|---|
Experimental: QLB type 2 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. |
Procedure: QLB
QLB, quadratus lumborum block.
Procedure: Intravenous patient controlled analgesia (PCA)
Intravenous patient controlled analgesia (PCA) pump was used to supply additional analgesia and removed 48 h post-operationally.
|
Experimental: QLB type 3 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. |
Procedure: QLB
QLB, quadratus lumborum block.
Procedure: Intravenous patient controlled analgesia (PCA)

|
Experimental: QLB type 2+3 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. |
Procedure: QLB
QLB, quadratus lumborum block.
Procedure: Intravenous patient controlled analgesia (PCA)
Intravenous patient controlled analgesia (PCA) pump was used to supply additional analgesia and removed 48 h post-operationally.
|
Active Comparator: epidural anesthesia group (EA) 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. |
Procedure: QLB
QLB, quadratus lumborum block.
Procedure: Intravenous patient controlled analgesia (PCA)
Intravenous patient controlled analgesia (PCA) pump was used to supply additional analgesia and removed 48 h post-operationally.

Outcome Measures
Primary Outcome Measures
- the change trend of Visual Analogue Scale (VAS) at rest and movement [0-48 hours postoperatively]
The purpose is to view the change of the level of pain assessed by subjects at adjacent time points. We would set 0, 4, 6, 12, 24, 48 hours postoperatively as observational time points.
Secondary Outcome Measures
- total morphine consumption [0-48 hours postoperatively]
total morphine consumption
- complications [0-48 hours postoperatively]
nausea, vomiting, retention of urine, lower limb weakness, etc.
