Randomized Study of Spinal Anesthesia Compared With Traditional Epidural Anesthesia Concerning Peroperative and Postoperative Pain After Open Nephrectomy in Patients With Renal Cell Carcinoma (ASA)

The study aim to study whether spinal anesthesia (using: bupivacain, morfin och klonidin) can be better than epidural anesthesia during and after open surgery for renal cell carcinoma. Per- and postoperative pain after spinal anesthesia with klonidin can be reduced and, thus, shorten the hospital stay and rehabilitation of the patients.
