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

Not Applicable

Completed

• Conditions: Postoperative Pain
• Interventions: Procedure: Thoracic paravertebral block; Procedure: Transversus abdominis plane block

• Registration Number: NCT04697420
• Lead Sponsor: Assiut University

Brief Summary

Pain relief after renal surgeries is essential as it may lead to reduction in the incidence of many post operative complications .

There are a lot of regional anesthetic techniques to provide analgesia postoperatively as paravertebral block (PVB) and transversus abdominis plane (TAP) block.

TAP block has been used to provide postoperative analgesia in a lot of abdominal surgeries including upper abdominal surgeries.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 .

Detailed Description

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 .

Arm && Interventions

Group	Intervention	Description
Group (P)	Thoracic paravertebral block	the patients were received paravertebral block to control pain postoperatively.
Group (T)	Transversus abdominis plane block	the patients were received transversus abdomins plane (TAP) block to control pain postoperatively.

Primary Outcome Measures

Name	Time	Method
comparison between the post operative analgesic effect of transversus abdominis plane block and paravertebral block	24 hours	comparison between the post operative analgesic effect of transversus abdominis plane block and paravertebral block by the following assessment methods: Visual Analogue Scale score (VAS) immediately postoperative and through the first 24 hours postoperativly, total analgesic consumption through the first 24 hours postoperatively, and time of first analgesic request in the postoperative period
