Brief Summary:
Quadratus lumborum block as an alternative for postoperative analgesia compared with epidural block

Condition or disease Intervention/treatment Phase
Postoperative Pain Procedure: Continuous Epidural analgesia Procedure: Bilateral Quadratus Lumborum block Not Applicable

Detailed Description:
Epidural analgesia is the main choice of analgesia following kidney transplant surgery. However, continuous epidural technique had some concerning side effects such as hemodynamic instabilities, urine retention, motor/sensory disturbances/weakness, and mobilisation comfort, it could also cause hypotension which could affect graft success. Quadratus lumborum (QL) block had lesser side effects thus could be an option for postoperative analgesia, however there are no study showing the safety and success rate of QL block techniques for patients who underwent kidney transplant surgery.

Arm Intervention/treatment
Active Comparator: Continuous Epidural Analgesia
Continuous epidural analgesia using ropivacaine 0.375% 3 mL boluses followed by ropivacaine 0.2% with rate 6 mL per hour for 24 hours
Procedure: Continuous Epidural analgesia
Continuous Epidural catheter is inserted at the Thoracic 11-T12 level, using Ropivacaine 0.375% 3 mL bolus followed by Ropivacaine 0.2% with rate 6 mL/hour for 24 hours after laparoscopic nephrectomy

Experimental: Bilateral Quadratus Lumborum Block
Bilateral Quadratus lumborum block using ropivacaine 0.2% 20 mL each injection after surgery
Procedure: Bilateral Quadratus Lumborum block
Bilateral anterior Quadratus Lumborum block using Ropivacaine 0.375% 20 mL each injection as postoperative analgesia treatment for 24 hours

Primary Outcome Measures :
  1. Visual Analogue Scale [ Time Frame: 24 hours ]
    pain measurement using Visual Analogue Scale (VAS) presented with horisontal line 0-100 mm for no pain to the worst pain, with range 0-30 mm for none to mild pain, 31-70 mm for moderate pain, 71-100 mm for severe pain

Secondary Outcome Measures :
  1. Morphine consumption [ Time Frame: 24 hours ]
    addtional analgesia required

  2. Blood ropivacaine level [ Time Frame: 24 hours ]
    Arterial blood sample of all subjects will be withdrawn 2 mL from the arterial line at baseline, 30,45,60 minute, and at 2,4,6,12, 18, 22 hours, and will be used for ropivacaine blood level measurements using High Performance Liquid Chromatography (HPLC), to measure Total plasma ropivacaine concentration (Cstop), maximum plasma concentration (Cmax), time of maximum palsma concentration, area under the curve (AUC)
