Overview

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.

Eligibility

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
