Anesthesia sTrategy foR Organ Procurement In braiN dEath

"In the volatile anesthetic group, sevoflurane will be administrated during the organ procurement procedure. Administration will be initiated progressively after moving in the operating room and will be pursued until aortic clamping (targeted end-expiratory concentration suggested between 1 and 2%).~No opioid agent (or intravenous hypnotic agent) will be allowed in this group."

In the opioid anesthetic group, intravenous sufentanil will be administrated during the organ procurement procedure. Continuous administration will be initiated after moving in the operating room (suggested dosage : 0,3 µg/kg/h) with supplemental dose if needed (at the discretion of the anesthesia team) and will be pursued until aortic clamping. No hypnotic drug administration will be allowed in this group.

"In all groups (experimental and control groups), neuromuscular blocking agents will be administered during the entire procedure, according to national guidelines. In all groups, hemodynamic management (use of vasoactive agents as vasopressors or anti-hypertensive drugs) will be done according to the discretion of the anesthesia team.~In all groups, all the others aspects of the donor management will be not modified by the study protocol."
