Patients who received a tranversus abdominis plane block with ultrasound after standard general anesthesia represented Group 1.

The tranversus abdominis plane block was performed bilaterally by obtaining an image with real time ultrasound guidance with a 6-13 MHz linear probe.

The block was placed with a 22 G 80 mm needle while obtaining real-time images via an in-plane technique.

Two 20 mL syringes were prepared after preparing a local anesthetic concentration of 1.5 mg/kg of 0.5% bupivacaine to 40 mL with saline. These were administered to the left and right abdominal walls.

Postoperative analgesia was administered through a morphine the patient-controlled analgesia device.

Patients who received standard general anesthesia alone made up Group 2. Postoperative analgesia was administered through a morphine the patient-controlled analgesia device.

Cases to whom used bupivacaine with ultrasound guided transversus abdominis plane block was applied after standard general anesthesia were determined as Group 1

Pain scores were assessed using a visual analog scale (0: No pain, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10: Excruciating pain).

morphine consumption were measured in postoperatively 24 hours
