PEEP for Cardiac Surgery Patients

This trial tests a new method of using PEEP, a setting on a breathing machine, to assist patients undergoing heart surgery. Researchers aim to understand how varying PEEP levels impact heart function and blood flow during surgery. The trial uses a special tool, Electrical Impedance Tomography (EIT), to guide these adjustments. It targets adults undergoing heart surgery, particularly those with conditions like pulmonary hypertension or right-sided heart issues. Participants must be scheduled for surgery with specific monitoring tools already planned as part of their care. As an unphased trial, this study allows patients to contribute to innovative research that could enhance surgical outcomes for individuals with complex heart conditions.

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.

Research has shown that using EIT-guided PEEP (Positive End-Expiratory Pressure) is generally safe for patients. In one study, patients who received this treatment had better oxygen levels during surgery compared to other methods. This technique uses electrical signals to determine the optimal PEEP levels for each person, helping to protect the lungs during surgery.

Another study found that this method improves lung function without causing serious side effects. Safety checks are in place during these treatments; for instance, if a patient's heart rate or breathing becomes too fast or too slow, doctors may pause the process to ensure safety.

Researchers are excited about the EIT Guided PEEP Trial because it offers a new method for optimizing ventilation settings during cardiac surgery. Unlike standard practices that rely on fixed PEEP (Positive End-Expiratory Pressure) settings, this approach uses Electrical Impedance Tomography (EIT) to tailor PEEP levels to each patient's unique lung characteristics. This personalized strategy could improve lung function and outcomes during and after surgery, potentially reducing complications and enhancing recovery.

Research has shown that using Electrical Impedance Tomography (EIT) to guide positive end-expiratory pressure (PEEP) can significantly improve oxygen distribution in the lungs during surgery. In this trial, participants in the Optimized PEEP Group will undergo an incremental/decremental PEEP trial using EIT. Studies have found that EIT-guided PEEP distributes air more evenly in the lungs and increases oxygen levels more effectively than traditional methods. For patients with low oxygen levels, this approach proved more effective in boosting blood oxygen. The technique is non-invasive, requiring no surgery, and can be performed at the bedside, making it a safe and practical choice. Overall, EIT-guided PEEP has demonstrated clear benefits in enhancing lung function during surgery.¹²⁶⁷⁸
