TAP BLOCK
CONTROL
Patients included in the ETAP group will receive the combination of a bilateral ultrasound-guided Transversus Abdominis Plane (TAP) block and a multimodal intravenous analgesia protocol for the postoperative pain management after the surgical open repair of an aortic abdominal aneurysm. The TAP block consists in 2 ultrasound-guided injections of Ropivacaine 0.375% on each side of the abdominal wall between the internal oblique and transversus abdominis muscles: 1 subcostal injection and 1 supra-iliac injection (i.e 10 ml of Ropivacaine 0.375% by injection). The multimodal intravenous analgesia protocol consists in the association of intravenous infusion of 1 g of Acetaminophen every 6 h and intravenous patient-controlled analgesia (PCA) with Chlorhydrate of Morphine 1 mg/ml.
Patients included in the CONTROL group will receive a multimodal intravenous analgesia protocol alone for the postoperative pain management after the surgical open repair of an aortic abdominal aneurysm. The multimodal intravenous analgesia protocol consists in the association of intravenous infusion of 1 g of Acetaminophen every 6 h and intravenous patient-controlled analgesia (PCA) with Chlorhydrate of Morphine 1 mg/ml.
