Implementation of Hemodynamic Management with the Hypotension Prediction Index during Elective Open Abdominal Aortic Surgery: A Pilot Observational Report

Intra-operative hypotension (IOH) is associated with a poor post-operative outcome. Consequently, it seems important to reduce the incidence of hypotensive events during anesthesia. The HemosphereTM (Edwards Lifescience Co., Irwin, CA, USA) platform provides the Hypotension Prediction Index (HPI), a predictive marker for a drop in blood pressure within a few minutes. We report the results of one year of application of a simple HPI-algorithm aiming at reducing the incidence of IOH in open abdominal aortic repair (oAAr), a type of surgery during which hemodynamic stability is notably challenging.
