Comparison of the Effects of Perioperative Anesthesia Consumption of Ultrasound Guided Subcostal Transversus Abdominis Plane and Paravertebral Block in Laparoscopic Cholecystectomy

Ultrasonography Assisted Subcostal TAP blockage: In plane technique was applied and 22 G needle (BRAUN Stimuplex D Plus 0,71\*50 mm 22G\*2) was used. Intravascular injection was eliminated after the passage of rectus sheath by negative aspiration. 0,5-1 ml local anesthetic was applied directly to confirm the right place. 10 cc bupivacain ( 0,5 % Marcain flacon, Astra Zeneca, Sweeden) and 5 cc lidocaine was injected to the site. The same procedure was applied to the opposite site. we investigated amount of TIVA during the operation, postoperative Visual Analog Scores and the time that the pain free time.

Ultrasonoraphy assisted Thoracic Paravertebral blockage application: In-plane or out-of-plane technique was used with stimuplex needle (BRAUN Stimuplec D Plus 0,71\*50 mm 22 G\* 2'', 15°). Popping sensation that was felt by the penetration of the internal intercostal membrane, guided to paravertebral space. Intravascular injection was eliminated by negative aspiration. 0,5 - 1 ml local anesthetic injection was administered to show the displacement of pleura downward that confirmed the place of the needle in the right place. Then 10 cc bupivacain (% 0.5 Marcaine® flacon, Astra Zeneca, Sweeden) and 5 cc lidocaine was injected to the site. we investigated amount of TIVA during the operation, postoperative Visual Analog Scores and the time that the pain free time.
