Highlights a potential life-threatening complication (myocardial ischaemia) associated with acute normovolaemic haemodilution prior to aortic aneurysm repair.
Answers are grounded in this paper and cite their sources.
May warrant caution with acute normovolemic haemodilution in aortic aneurysm repair; single case report leaves safety questions open for prospective study.
Acute normovolaemic haemodilution (ANH) is widely used as part of a blood conservation strategy to minimize the use of allogenic blood in the peri-operative period. Its role has not been proven in a prospective randomized trial. The potential benefits must not blind clinicians to the possible hazards. We report a life-threatening complication of ANH prior to induction of anaesthesia for aortic aneurysm repair.
