Venous-to-Arterial pCO2 Difference in High-risk Surgical Patients

Alteration of tissue perfusion is a main contributor to organ dysfunction in high-risk surgical patients. The difference between venous carbon dioxide and arterial carbon dioxide pressure (pCO2 gap) has been described as a parameter reflecting tissue hypoperfusion in critically ill patients who are insufficiently resuscitated.

The Brazilian Society for Cardiovascular Surgery (SBCCV) and Brazilian Society for Extracorporeal Circulation (SBCEC) Standards and Guidelines for Perfusion Practice

A primary role for clinical medicine societies is to develop standards and guidelines for practice as an instrument to promote safe and effective patient care. The Brazilian Society for Cardiovascular Surgery (SBCCV) represented by its Department for Mechanical Circulatory Assistance (DECAM) and the the Brazilian Society for Extracorporeal Circulation (SBCEC) conducted a careful critical review…

Lung Protection Strategies during Cardiopulmonary Bypass Affect the Composition of Blood Electrolytes and Metabolites – A Randomized Controlled Trial

This sub-study of the Pulmonary Protection Trial aimed to elucidate changes in arterial blood gas analyses, inflammatory protein interleukin-6, and metabolites of 90 chronic obstructive pulmonary disease patients following two lung protective regimens of pulmonary artery perfusion with either hypothermic histidine-tryptophan-ketoglutarate (HTK) solution or normothermic oxygenated blood during CPB, compared to the standard CPB with no pulmonary perfusion.
