Study Comparing Two Methods of TransversusAbdominis Plane

Randomised Study of Noninferiority Comparing a TransversusAbdominis Plane Block Surgical (c-TAP Block) to the Ultrasound-guided Abdominis Plane Block Transversus (Us-TAP Block) in Postoperative Analgesia After Laparoscopy or Laparotomy

Interventional, randomised, prospective, multicentric study

Interventional, randomised, prospective, multicentric and single blind study
