Abstract Introduction This retrospective study investigated the relationship between differing thresholds of Conventional Ultrafiltration (CUF) and postoperative hemoglobin (HGB) in cardiac surgery cases involving cardiopulmonary bypass. Methods The study utilized..

Abstract Background The decision regarding intraoperative transfusion has traditionally been based on hemodynamic instability and estimated blood loss. We performed a systematic review to determine the validity of the oximetry..

Abstract Objective The hemoglobin threshold for a decision to transfuse red blood cells in univentricular patients with parallel circulation is unclear. A expertise initiative put forth a “weak recommendation” for avoiding..

Abstract Background Extracorporeal circulation auxiliary to open heart surgery is a common procedure used to treat heart diseases. However, the optimal transfusion strategy for patients undergoing this surgery remains a..

Abstract Background Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is used as a rescue strategy for patients with refractory post-cardiotomy cardiogenic shock (PCS). These patients often have varying degrees of reduced hemoglobin..

Abstract Background Rapid fluid administration may decrease hemoglobin concentration (Hb) by a diluting effect, which could limit the increase in oxygen delivery (DO2) expected with a positive response to fluid..

Critical Preoperative Hemoglobin Value to Predict Anemia-Related Complications After Cardiac Surgery
Abstract Objectives Preoperative anemia is frequent in patients undergoing cardiac surgery and is associated with increased postoperative complications. Design A retrospective observational cohort study. Setting A tertiary-care medical center from..

Postoperative Nadir Hemoglobin and Adverse Outcomes in Patients Undergoing On-Pump Cardiac Operation
Abstract Background Patients undergoing cardiac operation are susceptible to anemia. Low hemoglobin concentration is a risk factor for composite adverse events and death after cardiac operation. Here we investigated the association of..

Lecture and discussion on optimizing hemoglobin and why hemoglobin thresholds alone may not be best for assuring adequacy of perfusion during open heart surgery.

Abstract Background Recent guidelines on transfusion in cardiac surgery suggest that hemoglobin might not be the only criterion to trigger transfusion. Central venous oxygen saturation (Svo2), which is related to..

Abstract Perioperative anemia is an important risk factor for cardiac surgery-associated acute kidney injury (CSA-AKI). Nonetheless, the severity of the anemia and the time in the perioperative period in which..

Abstract Purpose: We describe an approach for anticoagulation and transfusions in veno-venous–extracorporeal membrane oxygenation (VV-ECMO), evaluating factors associated with higher transfusion requirements, and their impact on mortality. Methods: Observational study..

Abstract Objectives: Pao2/Fio2 is used commonly for diagnosis of lung injury (acute respiratory distress syndrome and transfusion-related acute lung injury), for assessment of pulmonary disease course and therapy, and in pulmonary..

Abstract Anemia is an common condition in patients undergoing cardiac surgery, and it is often present in one quarter to half of patients at admission. Several studies have indicated that..

Abstract Introduction: Increasing the hematocrit is considered to increase oxygen delivery to the patient, especially when hypoxic conditions exist and the patient may become more stable. The aim of this..

Abstract Objective Hemolysis, characterized by formation of free hemoglobin (Hb), occurs in patients undergoing cardiopulmonary bypass (CPB). However, there is no study of the dynamic changes in red blood cell..
