Under complete aseptic precaution, Patient will be in lateral decubitus position a paravertebral catheter will be placed by the surgeon before closure of thoracotomy wound. The catheter will be introduced percutaneously through 18 gauge needle into the pleural cavity. The tip of catheter will be loaded by anaesthesiologist with 0.25 % isobaric bupivacaine with 20 ml followed by continuous infusion with bupivacaine 0.25 % at 6-8 ml per hour
Under complete aseptic precaution, patient will be in lateral decubitus position a paravertebral catheter will be placed by surgeon into pleural cavity and will not be loaded with bolus dose. At the end of surgery the (consultant anaesthesiologist) will perform intrathoracic unilateral intercostal nerve block two level above and two level below and at site of incision with 4 ml per level of 0.25 % bupivacaine followed by continuous infusion with 0.25 % bupivacaine at 6-8 ml/hour through catheter placed in paravertebral space.
