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.

Conditions

  • Regional Anaesthesia
  • Transversus Abdominis Plane Block

Interventions

PROCEDURE

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)

PROCEDURE

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)
