Summary

60 patients ASA I-III, undergoing open nephrectomy will be randomly assigned into one of two groups, namely group A (n=30), where a thoracic paravertebral block will be performed preoperatively and a paravertebral catheter for continuous and patient controlled bolus local anesthetic (ropivacaine) doses will be inserted and group B (n=30) where morphine IV will be administered at the beginning and the end of operation and postoperatively through patient controlled IV doses. NRS scores in static and dynamic conditions, complications, patient satisfaction, oxidative stress (through lactic acid, superoxide dismutase, malondialdehyde) and NGAL pre- and postoperatively, will be recorded.
