Summary
The ETAP study aim to assess the effect of the addition of an ultrasound-guided transversus abdominis plane (TAP) block to a multimodal intravenous analgesia protocol on the postoperative pain control in open surgical repair of abdominal aortic aneurysm. The ETAP study is a single-center open-label randomized controlled trial. Half of patients included will receive the association of TAP block and multimodal intravenous analgesia, and the other half will receive the multimodal intravenous analgesia alone. The multimodal intravenous analgesia includes intravenous paracetamol and intravenous patient-controlled analgesia with morphine.
