Transversus Abdominis Plane Block Versus Paravertebral Block for Post Operative Pain Relief in Open Renal Surgeries

Pain relief after renal surgeries is essential as it may lead to reduction in the incidence of post operative respiratory complications . A lot of patients presented to these operations may have comorbidities as impaired renal function and respiratory problems , conditions like these may contraindicate aministration of systemic analgesia as opioids . There are a lot of techniques to provide analgesia postoperatively as paravertebral block (PVB) and transversus abdominis plane (TAP) block . Paravertebral block is effective technique for post operative analgesia for upper abdominal surgeries , but it may be associated with some complications as : pneumothorax , spread of local anesthetic to the epidural space and paravertebral blood vessels , and this may lead to systemic toxicity of local anesthetic . TAP block has been used to provide postoperative analgesia in a lot of abdominal surgeries including upper abdominal surgeries , but it is safer technique than PVB , but the effectiveness of TAP block is unknown in comparison with PVB in post operative analgesia after renal surgeries .
