Subcostal Approach to Anterior Quadratus Block Versus Thoracic Paravertebral Block for Laparoscopic Nephrectomy

"S-QLB3 block will be performed 30 min. before general anesthesia. For anterior QL block via subcostal approach, 0.4 ml/kg of 0.25% bupivacaine + 1:400.000 adrenaline will be injected into the interfacial plane between the QLM and PMM.~IV-PCA: The requested dose will be 20µg/kg morphine, the lock-in time will be 6-10 minutes, the 4-hour limit will be 80% of the total calculated dose."

"TPVB block will be performed 30 min. before general anesthesia. TPVB will be performed at T10 transverse process level, 0.4 ml/kg of 0.25% bupivacaine + 1:400.000 adrenaline will be injected into the paravertebral space.~IV-PCA: The requested dose will be 20µg/kg morphine, the lock-in time will be 6-10 minutes, the 4-hour limit will be 80% of the total calculated dose."
