Hypotension Prediction Index and Intraoperative Hypotension Incidence

"BP, ECG and SpO2 were monitored after entering the operating room, peripheral venous access was established, radial artery puncture catheterization under local anesthesia and connected to the HPI (Edwards Lifesciences).~The treating anesthetist is trained to understand Acumen IQ parameters and the meaning of HPI, MAP, CI, SVI, SVR, SVV, Eadyn, dP/dtmax. The treating anesthetist is provided with guidance by means of a flowchart suggesting when to treat and how to treat hypotension. The hemodynamic management is performed according to the HPI guided algorithm."

BP, ECG and SpO2 were monitored after entering the operating room, peripheral venous access was established, radial artery puncture catheterization under local anesthesia and connected to TruWave DPT and run data via HemoSphere machine (Edwards Lifesciences). The target of intraoperative blood pressure was to maintain MAP \> 65mmHg. Timing of treatment and choice of treatment is then left to the discretion of the attending physician.
