NCT02645903

Brief Summary

Living donor organ transplantation has increased in recent years due to an increased need for organs. The objective of this study was to investigate the effects of a TAP block on postoperative analgesia and opioid consumption in liver transplantation donors in whom a right lateral extending upper mid-line abdominal incision was used.

Outcome Measures

Primary Outcomes (1)

  • pain scores (at movement and at rest)

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

    postoperatively at 24 hours

Secondary Outcomes (1)

  • morphine consumption

    postoperatively at 24 hours

Study Arms (2)

transversus abdominis plane block

ACTIVE COMPARATOR

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.

Drug: Transversus Abdominis Plane Block

nonblocked

PLACEBO COMPARATOR

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

Drug: standard general anesthesia

Interventions

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

Also known as: Marcaine plain+morphine
transversus abdominis plane block

Cases to whom applied alone standard general anesthesia were determined as Group 2

Also known as: morphine
nonblocked
