TMQLB Versus TPVB for Acute Pain and Quality of Recovery After Laparoscopic Renal Surgery

The patient is placed in the lateral position. The curved (C1-5) probe of Philip CX50 Ultrasound Scanner is used for scan and located vertical to the iliac crest at the posterior axillary line to find the Shamrock sign. The 22-G needle is then inserted in plane and directed to the QL muscle. After the proper position of the needle tip between the psoas major muscle and the quadratus lumborum muscle is confirmed, 0. 4 ml/kg 0.5% ropivacaine with 1: 200,000 adrenaline is injected into the interfascial plane. Followed by IPCA in the first 48h after surgery: morphine boluses: 1.5-2 mg, lockout time :10 min, 1h limitation: 6-8 mg morphine.

The 22-G needle is then inserted in plane and directed to the QL muscle. After the proper position of the needle tip between the psoas major muscle and the quadratus lumborum muscle is confirmed, 0. 6 ml/kg 0.5% ropivacaine with 1: 200,000 adrenaline is injected into the interfascial plane. Followed by IPCA in the first 48h after surgery: morphine boluses: 1.5-2 mg, lockout time :10 min, 1h limitation: 6-8 mg morphine.
