CARDIOPULMONARY BYPASS

This study tested whether doctors could safely give fewer blood transfusions during heart surgery by using a special monitor that checks how much oxygen the body's tissues are using. Researchers compared two groups of 676 adult heart surgery patients: one group received transfusi…

This study tested whether a combination of protective treatments during heart valve surgery could reduce heart muscle damage compared to standard care. Researchers enrolled 210 patients undergoing aortic valve surgery and measured heart injury markers for 72 hours after surgery. …

This study tested a new way to calculate the dose of the blood-thinner heparin for obese patients during heart surgery using a heart-lung machine. Researchers compared dosing based on a patient's ideal body weight versus their total weight to see if it prevented excessive blood t…

This study tested whether a sedative drug called dexmedetomidine could help protect the heart during and after major open-heart surgery. Researchers enrolled 224 patients undergoing this type of surgery to see if the drug reduced levels of a protein that signals heart muscle dama…

This study tested whether using a gentle, low-volume breathing technique during heart surgery could reduce the risk of post-surgery delirium, a common and serious type of confusion. Researchers compared this technique to stopping breathing entirely during a specific part of the o…

This study tested if a simple, non-invasive eye ultrasound could detect dangerous pressure changes in the brain during open-heart surgery. Researchers measured the width of the optic nerve sheath in 40 adult patients at different points during their operation. The goal was to see…

This study compared two different solutions used to protect the heart during coronary artery bypass surgery. Researchers enrolled 40 patients undergoing bypass surgery and monitored their recovery for 48 hours after the procedure. The goal was to understand which protection metho…

This study aimed to better understand the heart muscle damage that can occur during open-heart surgery using a heart-lung machine. Researchers used detailed heart MRI scans and frequent blood tests to measure this damage in 38 patients who had aortic valve surgery. The goal was t…

This study aimed to understand why blood pressure readings can differ between the body's core and limbs during heart-lung bypass surgery. Researchers measured pulse waves in 40 patients undergoing scheduled heart surgery to see if this difference could be reliably detected. The g…
