CARDIOVASCULAR Jugular bulb desaturation during coronary artery surgery: a comparison of off-pump and on-pump procedures{z

چکیده
Background. Conventional coronary artery bypass surgery has been associated with cerebral injury attributed to cardiopulmonary bypass (CPB) and surgical manipulation of the ascending aorta. Off-pump coronary artery surgery avoids these factors and could prevent cerebral injury. However, moving the heart from its natural position affects the circulation and could compromise cerebral oxygenation and perfusion. We set out to compare episodes of poor global cerebral oxygenation, defined as a jugular bulb saturation less than 50%, between patients randomized to off-pump or (conventional) on-pump coronary artery surgery.

Introduction: Coronary artery bypass grafting is a surgical operation that bypasses atherosclerotic coronary vessels and restores blood flow to the ischemic zone of hearts. And two different conventional methods are ON-pump CABG, and Off-pump CABG. Altogether, the efficacy and safety of these two types of surgical procedures are still under debate. In this study, we aim to com...

Introduction: Coronary artery disease (CAD) is the most common type of heart disease, with a mortality rate of 385,000 person per year in the United States. There are two main methods for CAD treatments: angioplasty and bypass surgery. Coronary Artery Bypass Grafting (CABG) is one of the greatest surgical operations of the 20th century and it is presented as most effective and long-term therapi...

Certain benefits are clearly associated with the use of off-pump coronary artery bypass grafting (CABG) as compared with the on-pump CABG. The superiority is more evident in patients with multiple co morbidities including renal failure.We reviewed the medical records of a 67-year-old male with a past medical history that was significant for multiple cardiovascular diseases and new-onset end-sta...
