The Hypotension Prediction Index in Major Abdominal Surgery

Status Not yet recruiting

Clinical Trial Summary

The goal of this randomized clinical trial is to compare different types of advanced hemodynamic monitoring in patients undergoing major abdominal surgery. Participants undergoing major abdominal surgery will receive anesthesia with two different types of hemodynamic monitoring - group A will receive arterial pressure cardiac output algorithm with the FloTrac sensor and group B will receive hemodynamic monitoring with the Hypotension Prediction Index. The main question the study aims to answer is: • will the hypotension prediction index algorithm reduce the rate of hypotension in comparison to arterial pressure cardiac output algorithm.

Clinical Trial Description

The fundamental aspect of the anesthetics perioperative management is to maintain hemodynamic stability, with special attention on the avoidance or reduction of the episodes of intraoperative hypotension (IOH). The incidence of intraoperative hypotension is related to an increased rate of perioperative morbidity and mortality. Even a short period of hypotension can be related to an increased risk of postoperative stroke, myocardial injury and acute kidney injury. Patients undergoing major abdominal surgery are at a high-risk of IOH because such surgeries typically require more than 2h to complete and require blood transfusion or inotrope administration. Hemodynamic monitoring and the use of goal directed therapy protocols helps to diminish the incidence of perioperative complications, however the hypotension management remains a reactive approach, an intervention is made when the hypotension has already occured. The Hypotension Prediction Index is an machine learning algorithm which allows to predict the episodes of hypotension and intervene before mean arterial pressure drops below 65 mmHg. The aim of the current study is to compare the rate of hypotension in patients undergoing major abdominal surgery with the arterial pressure cardiac output algorithm and the hypotension prediction index algorithm. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
