OBJECTIVE: Intraoperative blood management during cardiac surgery is a multifaceted process incorporating various interventions directed at optimizing oxygen delivery and enhancing hemostasis. The purpose of this study was to evaluate the effects of acute normovolemic hemodilution (ANH) and autologous priming (AP) on preserving the hematocrit during cardiopulmonary bypass (CPB). METHOD: Case records from a national registry of adult patients who underwent cardiac surgery between January and October 2016 were reviewed...

INTRODUCTION: We report a case of renal replacement therapy (RRT) during extracorporeal membrane oxygenation (ECMO) via a single venous access and analyze the feasibility of transpulmonary thermodilution (TPTD) for hemodynamic monitoring. CASE REPORT: ECMO and RRT connected into the ECMO-extracorporeal circuit were performed via a single venous access because of multiple venous thromboses. An indicator for TPTD and pulse contour analysis (PCA) was applied into the central venous catheter (CVC) placed in the right vena jugularis...

INTRODUCTION: A number of large-scale retrospective studies revealed that off-pump coronary artery bypass (OPCAB) was superior to on-pump coronary artery bypass (ONCAB). The aim of the study was to investigate risk factors for mortality when OPCAB is converted to ONCAB. METHODS: Patients who underwent OPCAB conversion to ONCAB at the Beijing Anzhen Hospital between January 2003 and January 2013 were assigned to the non-survivor and survivor groups. Background demographics, illness history and preoperative, intraoperative and postoperative variables were compared...

BACKGROUND: Acute kidney injury (AKI) following cardiopulmonary bypass affects 5% of patients, representing significant postoperative morbidity and mortality. Animal models have shown an increased uptake of lipid microemboli (LME) into the renal vasculature, potentially indicating ischaemic causation. This study tested a new lipid filtration system (RemoweLL) against a conventional system with no lipid-depleting capacity to determine the efficacy of the filtration system and its effects on renal function...

The complete surgical resection of malignant thymoma is recommended. We present a rare case of tumor resection and superior vena cava (SVC) reconstruction under veno-venous bypass support from the left internal jugular vein to the left femoral vein. The full amount of systemic heparinization (3 mg/kg) was avoided. The surgical pathology revealed thymic squamous cell carcinoma. No complications such as fatal extensive bleeding, coagulopathy, thromboembolism or transfusion reaction were found postoperatively...

PURPOSE: Measuring myocardial strain using two-dimensional speckle tracking echocardiography has emerged as a new tool to identify subclinical ventricular dysfunction. Abnormal strain has been shown to have superior sensitivity compared with dobutamine stress echocardiography for viability assessment; however, there is a paucity of data regarding the prediction of long-term major adverse cardiac events. We compared the prognostic ability of both global longitudinal strain (GLS) from resting echocardiograms to regional wall motion score index (WMSI) from stress echocardiograms in their ability to predict long-term major adverse cardiac events...

BACKGROUND: Every year, over 1 million cardiac surgical procedures are performed all over the world. Reducing myocardial necrosis could have strong implications in postoperative clinical outcomes. Volatile anaesthetics have cardiac protective properties in the perioperative period of cardiac surgery. However, little data exists on the administration of volatile agents during cardiopulmonary bypass. The aim of this study was to assess if volatile anaesthetics administration during cardiopulmonary bypass reduces cardiac troponin release after cardiac surgery...

BACKGROUND: Long intervals of del Nido (DN) solution administration, 90 minutes, may result in rewarming of the myocardial tissue and elevate metabolic demand and hypoxia. This will potentially increase inflammatory response due to ischemia-reperfusion injury. We conducted this study to compare the inflammatory response between patients receiving DN and multi-dose St Thomas' cardioplegia solution (MST) in cardiopulmonary bypass (CPB) surgery for the correction of tetralogy of Fallot (TF)...

BACKGROUND: Myocardial tolerance to ischemia is influenced by age and preoperative cyanosis through unknown mechanisms and significantly affects postoperative outcomes. Cytochrome c oxidase (CcOx), the terminal enzyme of the mitochondrial electron transport chain, may play a role in the susceptibility to ischemic-reperfusion (IR) injury. Our study aimed at investigating changes in human myocardial CcOx activity based on age and preoperative oxygen saturation to understand its role in transition from neonatal to mature myocardium and hypoxic conditions...

BACKGROUND: Muscle tissue saturation (StO2) measured with near-infrared spectroscopy has generally been considered a measurement of the tissue microcirculatory condition. However, we hypothesized that StO2 could be more regarded as a fast and reliable measure of global than of regional circulatory adequacy and tested this with muscle, intestinal and brain metabolomics at normal and two levels of low cardiopulmonary bypass blood flow rates in a porcine model. METHODS: Twelve 80 kg pigs were connected to normothermic cardiopulmonary bypass with a blood flow of 60 mL/kg/min for one hour, reduced randomly to 47...

BACKGROUND: Myocardial damage is an independent predictor of adverse outcome following cardiac surgery and myocardial protection is one of the key factors to achieve successful outcomes. Cardioplegia with Custodiol is currently the most used cardioplegia during minimally invasive cardiac surgery (MICS). Different randomized controlled trials compared blood and Custodiol cardioplegia in the context of traditional cardiac surgery. No data are available for MICS. AIM: The aim of this study was to compare the efficacy of cold blood versus Custodiol cardioplegia during MICS...

Modified ultrafiltration (MUF) is a technique which is commonly used immediately post-cardiopulmonary bypass (CPB) for open heart surgery in children. There are many advantages of MUF, but there are also a number of less reported disadvantages. At our institution, after considering all of the available data, a decision was made to no longer perform MUF. The primary motivation being the simplified and miniaturized CPB circuit would reduce hemodilution, decrease our likelihood of reaching our transfusion trigger during CPB and, potentially, improve safety...

Spontaneous left main coronary artery dissection is a rare cause of acute coronary events or sudden cardiac death, constituting less than 1% of all epicardial coronary artery dissections. It is often fatal and is mostly recognized at post-mortem examination in young victims of sudden death. More than 70% of the reported cases occurred in women, particularly during pregnancy and the peripartum period and those on oral contraceptives. The clinical presentation is highly variable and prognosis varies widely, depending predominantly on the speed of diagnosis...

BACKGROUND: HemoSep(®) is a commercial ultrafiltration and haemoconcentration device for the concentration of residual bypass blood following surgery. This technology is capable of reducing blood loss in cardiac and other types of "clean site" procedures, including paediatric surgery. Clinical feedback suggested that the device would be enhanced by including a sensor technology capable of discerning the concentration level of the processed blood product. We sought to develop a novel sensor that can, using light absorption, give an accurate estimate of packed cell volume (PCV)...
