Description
Background: The Transversus Abdominis Plane (TAP) block is a recently introduced regional anesthesia method utilized for postoperative pain control, with the potential to serve as the primary anesthetic in a growing array of surgical procedures. TAP block enhances postoperative pain management by reducing postoperative visual analog scale scores, opioid requirements, and the time elapsed before the initial administration of rescue analgesia in patients undergoing lower abdominal surgeries. Aims and Objectives: In our research, we employed the TAP block as the exclusive anesthetic method for elective patients undergoing Lower Abdominal Surgeries. We then compared the effectiveness of two distinct local anesthetics, namely 0.5% Bupivacaine and 0.75% Ropivacaine, in terms of their duration of anesthesia and analgesia as well as their impact on cardiovascular stability. Materials and Methods: A prospective randomized clinical trial involved 60 patients classified as ASA I and II who met the specified inclusion and exclusion criteria. These patients were divided equally into two groups: Group B, which received an injection of 0.5% bupivacaine, and Group R, which received an injection of 0.75% ropivacaine. The dosage administered did not surpass 2.5 mg/kg body weight for any participant. Results and Conclusion: Our study revealed that both drugs provide effective anesthesia for Lower abdominal Surgeries while maintaining hemodynamic stability. However, 0.75% Ropivacaine exhibited a significant delay in the onset of anesthesia (13.46 +/- 3.2 min) compared to 0.5% Bupivacaine (7.86 +/- 2.47 min) (P value <0.001). Furthermore, 0.75% Ropivacaine resulted in prolonged postoperative analgesia (675.54 +/- 30.31 min) compared to 0.5% Bupivacaine (573 +/- 45.72 minutes) (P value <0.001). This suggests that the Transversus Abdominis Plane (TAP) block can serve as the sole anesthetic technique for Lower abdominal surgeries.
