- Original description
The aim of the current study is to evaluate the effects of the Hypotension Prediction Index (HPI) on the degree of intraoperative hypotension in patients undergoing free flap surgery. The hypothesis is that implementation of the HPI algorithm will reduce the time-weighted average (TWA) intraoperative hypotension below a threshold of 65 mmHg (16), and to reveal the relationship between the episodes of hypotension and free flap viability and function.Read full original descriptionShow less
The Hypotension Prediction Index in Free Flap Transplant in Head and Neck Surgery - a Prospective Randomized Controlled Trial.
The aim of the current study is to evaluate the effects of the Hypotension Prediction Index (HPI) on the degree of intraoperative hypotension in patients undergoing free flap surgery. The hypothesis is that implementation of the HPI algorithm will reduce the time-weighted average (TWA) intraoperative hypotension below a threshold of 65 mmHg (16), and to reveal the relationship between the episodes of hypotension and free flap viability and function.
Inclusion: Patients qualified to head and neck free flap surgery; Written informed consent.
Exclusion: Persistent atrial fibrillation and other arrhythmias impairing arterial pressure-based cardiac output (APCO) monitoring; Known history of congenital heart disease, severe aortic and/or mitral stenosis, heart failure and ejection fraction < 35 %; Patients under 18 years; Lack of health insurance; Pregnancy.
