Prospective, Randomized Comparative Study Between an Anesthesiological, Ultrasound-guided, and a Laparoscopic, Landmark-based Application of a "Transversus Abdominis Plane (TAP) Block" Based on Postoperative Pain Perception, Postoperative Analgesic Requirement, and Procedure Duration
Sponsor: Sana Klinikum Offenbach
Summary
The Transversus Abdominis Plane Block (TAP) has become one of the most established and frequently performed trunk wall blocks for perioperative analgesia in abdominal surgical procedures. The TAP-Block can be performed by both surgeons and anaesthetists. The goal of this prospective, randomized study is to compare an anesthesiological, ultrasound-guided "Transversus Abdominis Plane (TAP) Block" with a laparoscopic, landmark-based "Transversus Abdominis Plane (TAP) Block" The main questions it aims to answer are: Primary Hypothesis: There are no differences in postoperative pain perception and analgesic requirements between the anaesthesiological ultrasound-guided and the surgical laparoscopic landmark-based TAP block Secondary Hypothesis: There are no significant differences in the duration of the procedure between the anaesthesiological, ultrasound-guided and the surgical laparoscopic landmark-based TAP block.

Interventions
Arm 1: The anaesthesiologically performed, ultrasound-guided, 4 quadrant-TAP block ( a combination of a lateral with a subcostal TAP block bilaterally)
Injection of a total of 60 ml ropivacaine 0.2% into the target compartment (2x 20 ml laterally, 2x 10 ml subcostally)
Arm2: The surgically performed, laparoscopic landmark-based assisted TAP block
Injection of a total of 6 x 10 ml = 60 ml ropivacaine 0.2% into the target compartment (at 3 defined puncture sides bilaterally: at the anterior axillary line at 2 different, fixed heights and at the midclavicular line subcostally)
