Serum Lactate Poorly Predicts Central Venous Oxygen Saturation in Critically Ill Patients: a Retrospective Cohort Study
Serum lactate and central venous oxygen saturation (ScvO2) are commonly used and commonly recommended as markers of tissue oxygenation in shock states.
Ex Vivo Heart Perfusion for 72 Hours Using Plasma Cross Circulation
Preservation of a donor heart for transplantation is limited to 6–8 hours.
Blood Utilization in Revision Versus First-Time Cardiac Surgery: An Update in the Era of Patient Blood Management
Relative to first-time (primary) cardiac surgery, revision cardiac surgery is associated with increased transfusion requirements, but studies comparing these cohorts were performed before patient blood management (PBM) and blood conservation measures were commonplace. The current study was performed as an update to determine if this finding is still evident in the PBM era.
Nature of Cardiac Rehabilitation Around the Globe
Cardiac rehabilitation (CR) is a clinically-effective but complex model of care. The purpose of this study was to characterize the nature of CR programs around the world, in relation to guideline recommendations, and compare this by World Health Organization (WHO) region.
Heart Valve Operations Associated With Reduced Risk Of Death From Mitral Valve Disease But Other Operations Associated With Increased Risk of Death: A National Population-Based Case-Control Study
This study analyzed the death risk from heart valve disease with respect to the frequency of heart valve operation and other operations in patients with mitral valve disease.
Extracorporeal Membrane Oxygenation: Indications, Technique and Contemporary Outcomes
Extracorporeal membrane oxygenation (ECMO) is an advanced form of temporary life support, to aid respiratory and/or cardiac function. It has been used since the early 1970s and is based on cardiopulmonary bypass technology and diverts venous blood through an extracorporeal circuit and returns it to the body after gas exchange through a semi-permeable membrane.
Association Between Anemia and Blood Transfusion With Long-term Mortality After Cardiac Surgery
The aim of this study was to investigate the interactions between preoperative anemia and RBC transfusion and their effect on the long-term survival of patients undergoing cardiac surgery.
Neurologic Outcomes in Patients Who Undergo Extracorporeal Cardiopulmonary Resuscitation
This study aimed to develop a risk prediction model for neurologic outcomes in patients who underwent extracorporeal cardiopulmonary resuscitation (ECPR).
Use of Quality of Life in Cardiovascular Surgery in Coronary Artery Bypass Grafting: Validation, Reproducibility, and Quality of Life in One Year of Follow-Up
The objectives of this study are to validate the Quality of Life in Cardiovascular Surgery (QLCS) questionnaire and to observe the evolution of quality of life in the first year of postoperative follow-up of patients who underwent coronary artery bypass grafting (CABG).
A Century of Heparin
The year 2018 was the centennial of the naming of heparin by Emmett Holt and William Howell and the 102nd anniversary of Jay McLean’s discovery of an anticoagulant heparphosphatide at Johns Hopkins Hospital in Baltimore.
BloodSurf 2017: News From the Blood-biomaterial Frontier
From stents and large-diameter vascular grafts, to mechanical heart valves and blood pumps, blood-contacting devices are enjoying significant clinical success owing to the application of systemic antiplatelet and anticoagulation therapies.
Nitric Oxide Attenuates the Inflammatory Effects of Air During Extracorporeal Circulation
Cardiopulmonary bypass causes a systemic inflammatory response reaction that may contribute to postoperative complications. One cause relates to the air/blood interface from the extracorporeal circuit. The modulatory effects of blending nitric oxide (NO) gas into the ventilation/sweep gas of the membrane lung was studied in a porcine model of air-induced inflammation in which NO gas was added and compared with controls with or without an air/blood interface.
