The relationship between low intraoperative hematocrit levels during cardiopulmonary bypass and postoperative neurological events.
OBJECTIVE The objective of our study is to analyze whether low intraoperative hematocrit levels have an effect upon postoperative neurological events. METHODS Our study included 140 patients who underwent isolated coronary bypass under cardiopulmonary bypass between 2009 and 2012. The main group of the study was 70 patients with intraoperative hematocrit levels lower than 22%. These patients'...
متن کاملInfluence of intraoperative fluid volume on cardiopulmonary bypass hematocrit and blood transfusions in coronary artery bypass surgery.
A hematocrit (Hct) of less than 25% during cardiopulmonary bypass (CPB) and transfusion of homologous packed red blood cells (PRBC) are each associated with an increased probability of adverse events in cardiac surgery. Although the CPB circuit is a major contributor to hemodilution intravenous (IV) fluid volume may also significantly influence the level of hemodilution. The objective of this s...
متن کاملNadir hematocrit during cardiopulmonary bypass: end-organ dysfunction and mortality.
OBJECTIVE To discover the effects of the lowest hematocrit during cardiopulmonary bypass on end-organ function and mortality in patients who did not receive red blood cell transfusion and to identify predictors of nadir hematocrit. METHODS From November 1, 2004, to October 1, 2009, 7957 patients underwent cardiac surgery supported by cardiopulmonary bypass and were not transfused. The relatio...
متن کاملStrategies to prevent intraoperative lung injury during cardiopulmonary bypass
During open heart surgery the influence of a series of factors such as cardiopulmonary bypass (CPB), hypothermia, operation and anaesthesia, as well as medication and transfusion can cause a diffuse trauma in the lungs. This injury leads mostly to a postoperative interstitial pulmonary oedema and abnormal gas exchange. Substantial improvements in all of the above mentioned factors may lead to a...
متن کاملHemodilution and Hematocrit on Cardiopulmonary Bypass: How Low Can We Go?
Since 1953 when Dr. John Gibbons, Jr. and colleagues first successfully used cardiopulmonary bypass to perform an open mitral comissurotomy, the technology of the cardiopulmonary bypass (CPB) circuit and the physiologic management of patients during extracorporeal circulatory support have undergone a tremendous evolution. Despite major technologic advances and half a century of experience with ...
