Efficacy and effect of TIVA with propofol or dexmedetomidine versus sevoflurane without muscle relaxant during repair of the brachial plexus

Background: Paravertebral block has been established technique for providing analgesia to the chest and abdomen. We conducted the current study to compare single dose paravertebral block (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. Post-operative pain was assessed over 24hr using 10-cm visual analogue scale (VAS). Post operative total pethidine consumption was recorded. Any postoperative events like 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. Post operative VAS showed no significant difference between the studied groups. Post operative events were comparable in both groups Conclusion: Single injection paravertebral block 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
