Abstract

Introduction: Wall of abdomen is a source of pain after abdominal surgeries. Even an operation such as inguinal herniorrhaphymay lead to chronic pain in patients. Lower abdominal surgeries are common surgical procedure with a rare postoperative morbidity. However, chronic pain and continuous neuralgia have been accepted as complications after lower abdominal surgeries. Aims: To compare Effect of 0.25% Bupivacaine and 0.5% Ropivacaine in Transversus abdominis plane block for postoperative analgesia in lower abdominal surgeries. Materials and Methods: This is was a prospective study conducted at during the period from June 2017 to May 2018. Sixty patients with ASA Grade I and II of 20 to 60 years age, undergoing inguinal hernia surgeries under spinal anesthesia were randomly alocated into Two Groups of 30 each, Group B - Bupivacaine 0.25% and Group R- Ropivacaine 0.5%. Results: Thus, the effect of Bupivacaine and Ropivacaine was comparable to each other suggesting that Bupivacaine and Ropivacaine have hemodynamic stability in TAP block. The duration of postoperative analgesia was for more than 24 hrs in Ropivacaine Group comparative to Bupivacaine has a postoperative analgesia for 8 hrs. Conclusion: TAP bock performed by landmark technique in patients undergoing lower abdominal surgeries with 0.5% ropivacainesingle injection of 0.5% ropivacaine gives prolonged postoperative analgesia, Reduces the doses of rescue analgesics in postoperative period.
