The timing of intubation and principles of ICU care in COVID-19.

Coronavirus disease-19 (COVID-19) has been a serious health problem since it was first identified in Wuhan, China, in December 2019 and has created a global crisis with its economic, sociological, and psychological aspects. Approximately 15% of cases have a severe clinical presentation, and 5% of patients require admission to the intensive care unit. A significant proportion of patients presents with a rapidly progressing acute respiratory failure and require invasive mechanical ventilation.

Effect of dilutional anemia that can be treated with only one unit of red blood cell transfusion on tissue oxygenation in cardiac surgery patients.

Background/aim: Cardiac surgery, especially in the presence of cardiopulmonary bypass (CPB), is associated with an inflammatory reaction that may promote microcirculatory alterations, in addition to the general impact on system hemodynamics. Anemia and transfusion make patients more susceptible to the deleterious effects of CPB. In this study, it was aimed to evaluate the effect of dilutional anemia, which is caused by CPB and can be treated with 1–2 units of red blood cell (RBC) transfusion, on global tissue oxygenation parameters in cardiac surgery patients.
