Comparison of Postoperative Analgesic Efficacy of the Erector Spina Plane Block and Quadratus Lumborum Block in Open Nephrectomy: a Prospective Randomized Clinical Study

Condition(s) studied

Investigational drug(s) / intervention(s)

preoperative remifentanil consumption: continuous remifentanil infusion will applied for peroperative analgesia

postopeartive controlled anlagesia with morphine: postoperative morphine patient controlled analgesia will be applied for postoperative analgesia
