Background: Paravertebral block (PVB) has been an established technique for providing analgesia to the chest and abdomen. We conducted the current study to compare single-dose PVB versus single-dose epidural blockade (EP) for pain relief after renal surgery. Methods: Eighty patients scheduled for renal surgery were randomly assigned into two groups according to the analgesic technique, PVB group or EP group. General anesthesia was induced for all patients. Postoperative pain was assessed over 24 h using 10-cm visual analog scale (VAS). Postoperative total pethidine consumption was recorded. Any postoperative events, such as nausea, vomiting, shivering, or respiratory complications, were recorded. Hemodynamics and blood gasometry were also recorded. Results: EP group showed significant decrease of both heart rate and mean blood pressure at most of the operative periods when compared with PVB group. There was no difference in total rescue analgesic consumption. Postoperative VAS showed no significant difference between the studied groups. Postoperative events were comparable in both the groups. Conclusion: Single injection PVB resulted in similar analgesia but greater hemodynamic stability than epidural analgesia in patients undergoing renal surgery, therefore this technique may be recommended for patients with coexisting circulatory disease.
