INTRODUCTION: In the literature addressing cardiopulmonary bypass (CPB) prime composition, there is a considerable lack of discussion concerning plasma osmolality changes induced by using a hyperosmolar prime. With this study, we try to determine the magnitude and temporal relationship of plasma osmolality changes related to the use of a hyperosmolar CPB prime. METHOD: In this prospective observational study performed in a university hospital setting, we enrolled thirty patients scheduled for elective coronary bypass surgery...

OBJECTIVES:  Increasing experience with minimally invasive cardiac (MIC) aortic valve (AV) replacement makes AV reoperations (rAVR) an appealing alternative to conventional redo surgery. The aim of the study was to compare the perioperative outcome after isolated MIC versus full-sternotomy (FS) rAVR. METHODS:  We retrospectively analyzed data of 116 patients from three centers who underwent rAVR by using a FS ( n  = 70, 60.3%) or a partial upper sternotomy approach ( n  = 46, 39...

During the perioperative period of cardiac disease, as many risk factors exist, such as primary cardiac diseases, the use of vasopressors, ischemia-reperfusion injury during cardiopulmonary bypass (CPB), and surgical stress, the gut suffered from ischemia, anoxia and oxidative stress, which would lead to the enterocyte injury. The aim of this study was to explore whether serum intestinal fatty acid-binding protein (IFABP), which is excreted specifically from damaged intestinal enterocytes, as a predictor of prognosis in postoperative cardiac surgery patients...

BACKGROUND: Most studies evaluating predictors of renal replacement therapy (RRT) following cardiac surgery use arbitrary defined limits of preoperative serum creatinine. The aim of this study was to evaluate the effect of preoperative renal function using either estimated-glomerular filtration rate (eGFR) derived using Chronic Kidney Disease-Epidemiology (CKD-EPI) or serum creatinine alone as a predictor for RRT after cardiac surgery. METHODS: In this prospective cohort study, baseline, intraoperative, and postoperative data of all patients who underwent an elective, urgent, or emergency cardiac surgery between 2012 and 2016 in a single center were analyzed in order to identify multivariate parameters determining the need for RRT after surgery...

To explore the effect of ulinastatin on perioperative glycocalyx and lung function in patients undergoing mitral valve replacement surgery.
 Methods: Fourty patients, undergoing mitral valve replacement, were randomly allocated into a control group and an ulinastatin group, which were administrated 50 mL normal saline or 2×104 U/kg ulinastatin at the beginning of cardiopulmonary bypass (CPB), respectively. The radical artery blood was collected at 4 time points: After induction of anesthesia (T0), at 10 min after the start of CPB (T1), 1 h after the end of CPB (T2), and 8 h after operation...

BACKGROUND: We have previously found that hyperkalemic cardioplegic arrest in the setting of cardiopulmonary bypass (CP/CPB) is associated with impairment of the coronary arteriolar response to phenylephrine in nondiabetic (ND) patients. We hypothesized that diabetes may alter coronary arteriolar response to alpha-1 adrenergic agonist in the setting of CP/CPB. In this study, we further investigated the effects of diabetes on the altered coronary arteriolar response to phenylephrine in patients undergoing cardiac surgery...

Cardiac surgery with cardiopulmonary bypass (CPB) triggers myocardial ischemia/reperfusion injury contributing to organ dysfunction. Preclinical studies revealed that dipeptidyl peptidase (DPP4) inhibition is protective during myocardial infarction. Here, we assessed for the first time the relation of peri-operative DPP4-activity in serum of 46 patients undergoing cardiac surgery with patients' post-operative organ dysfunction during intensive care unit (ICU) stay. Whereas a prior myocardial infarction significantly reduced pre-operative DDP4-activity, patients with preserved left ventricular function showed an intra-operative decrease of DPP4-activity...

BACKGROUND:  Neonates undergoing cardiopulmonary bypass (CPB) surgery to correct congenital heart defects often experience excessive bleeding. Exposure of blood to artificial materials during CPB may activate coagulation, complement and inflammatory pathways. In addition, the surgical stress placed on the haemostatic system may result in cross-activation of other plasma proteolytic cascades, which could further complicate physiological responses to the surgical procedure and post-operative recovery...

We report on a 61-year-old man with a previously unknown interruption of the inferior vena cava who was scheduled to undergo minimally invasive mitral and tricuspid valve surgery. We aimed to establish a cardiopulmonary bypass using femorofemoral cannulation under transoesophageal echocardiography. In spite of multiple attempts, the positioning of the venous wire in the right atrium was not accomplished. The intervention was subsequently performed by an open sternotomy. Further to the intervention, the patient underwent thoraco-abdominal multislice computed tomography that excluded the presence of an abdominal tumour or vena cava thrombosis but revealed atresia of the inferior vena cava...

INTRODUCTION: Allogeneic blood product transfusion is common in pediatric patients undergoing cardiopulmonary bypass although it is associated with an increased risk for adverse events. Furthermore, numerous donor exposures may affect future blood transfusion needs and human leukocyte antigen matching for patients who may ultimately require cardiac transplantation. Autologous intraoperative blood collection and retransfusion is a known method of blood preservation, but has not been extensively practiced in pediatric patients...

BACKGROUND: Cardiac surgery-associated acute kidney injury (AKI) is a serious complication of cardiac surgery, even when renal replacement therapy (RRT) is not required. The existing risk models for cardiac surgery associated AKI are designed to predict AKI requiring RRT (RRT-AKI). The aim of this study is to validate three risk models for the prediction of RRT-dependent and non-RRT AKI after cardiac surgery. METHODS: Retrospective analysis on 7675 consecutive adult patients undergoing cardiac surgery with cardiopulmonary bypass...
