ClinConnect Summary

This clinical trial is studying a new technique called Transesophageal Lung Ultrasound (TELUS) to help improve lung function during cardiac surgery, specifically coronary artery bypass surgery. The goal is to see if using this ultrasound method can reduce a condition known as lung atelectasis, which is when parts of the lung collapse and can cause breathing problems after surgery. Patients who participate will be randomly assigned to either receive the TELUS-guided technique or standard care during their surgery.

To be eligible for this trial, participants should be between 18 and 70 years old, scheduled for elective cardiac surgery that involves a special kind of heart test called transesophageal echocardiography (a type of ultrasound for the heart). They should also have a certain level of heart function and a specific risk score for surgery. However, individuals who are pregnant, have certain medical conditions affecting their lungs, or have had previous lung surgeries may not be eligible. This trial is not yet recruiting participants, so if you or someone you know is interested, keep an eye out for updates!
