Hypotension Prediction Index for Shoulder Surgery in Beach Chair.

Status Recruiting

Clinical Trial Summary

The beach chair position is the most commonly used position during shoulder surgery and offers the surgeon numerous advantages over the lateral decubitus position. However, the beach chair position can also lead to hemodynamic changes, including hypotension and cerebral hypoperfusion. It is therefore the anesthesiologist's job to prevent hypotension during the procedure. The Acumen Hypotension Predictor Index or HPI for short is a software program that can predict the occurrence of low blood pressure during surgery shortly before it occurs. Studies have already demonstrated the effectiveness of HPI in various operations, where hypotension is defined as a mean arterial blood pressure < 65mmHg for at least 1 minute. To our knowledge, the low blood pressure prediction index has not yet been investigated for the prevention of low blood pressure in shoulder surgery in the beach chair position. The HPI is built into a monitor that is switched on in addition to the standard monitoring for monitoring blood pressure, pulse, saturation, among other things. The monitor gives a signal when an episode of low blood pressure will occur within 15 minutes. This gives the anesthesiologist the opportunity to anticipate in time so that the occurrence of low blood pressure can be avoided. Goal The aim of this study is to evaluate the efficacy of the HPI in predicting and reducing the incidence of hypotension during shoulder surgery in the beach chair position. Procedure A total of 144 patients will participate in this study. Patients will be randomized to the intervention group or the control group according to a 1:1 allocation. In addition to standard monitoring, the HPI monitor will be turned on for all patients. For patients in the control group, the HPI monitor screen will be blinded and the alarms muted. Patients between 18 and 85 years of age with a BMI ≤ 40 kg/m2 undergoing elective shoulder surgery are eligible for the study.

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.
