Hypotension Prediction Index (HPI) in Patients Undergoing Robotic Assisted Radical Prostatectomy

Hypotension Prediction Index (HPI) in Patients Undergoing Robotic Assisted Radical Prostatectomy

Robot assisted radical prostatectomy (RARP) is the leader in robotic treatment for prostate cancer. Goal-directed therapy (GDT) is the approach used, but HPI, a machine learning algorithm analysing arterial waveforms, might offer additional benefits. The aim of this prospective randomised study is to evaluate the cumulative amount of intraoperative arterial hypotension episodes in patients undergoing RARP managed by GDT protocol guided or not by HPI algorithm

Inclusion Criteria:

• all consecutive patients undergoing RARP; American Society of Anaesthesiology (ASA) SCORE I-III

Exclusion Criteria:

• Body Mass Index (BMI) of 18.5 to 35, uncontrolled arrhythmias, myocardial infarction or ischemic/hemorrhagic stroke in the last 6 months, III/IV stage Global Initiative for Chronic Obstructive Lung Disease, pulmonary fibrosis, contraindication to radial artery cannulation.
