OBJECTIVES: Controversy remains regarding the use of deep hypothermic circulatory arrest (DHCA) in neonatal cardiac surgery. Alterations in cerebral mitochondrial bioenergetics are thought to contribute to ischaemia-reperfusion injury in DHCA. The purpose of this study was to compare cerebral mitochondrial bioenergetics for DHCA with deep hypothermic continuous perfusion using a neonatal swine model. METHODS: Twenty-four piglets (mean weight 3.8 kg) were placed on cardiopulmonary bypass (CPB): 10 underwent 40-min DHCA, following cooling to 18°C, 10 underwent 40 min DHCA and 10 remained at deep hypothermia for 40 min; animals were subsequently rewarmed to normothermia...

Background: Acute kidney injury (AKI) is a frequent complication of cardiac surgery. We sought prognostic combinations of postoperative biomarkers measured within 6 h of surgery, potentially in combination with cardiopulmonary bypass time (to account for the degree of insult to the kidney). We used data from a large cohort of patients and adapted methods for developing biomarker combinations to account for the multicenter design of the study. Methods: The primary endpoint was sustained mild AKI, defined as an increase of 50% or more in serum creatinine over preoperative levels lasting at least 2 days during the hospital stay...

Background -Cerebral injury is an important complication following cardiac surgery with the use of cardiopulmonary bypass (CPB). The rate of overt stroke after cardiac surgery is 1-2%, whereas silent strokes, detected by diffusion-weighed magnetic resonance imaging (DWI), are found in up to 50% of patients. It is unclear if a higher versus a lower blood pressure during cardiopulmonary bypass reduces cerebral infarction in these patients. Methods -In a patient- and assessor-blinded randomized trial, we allocated patients to a higher (70-80 mmHg) or lower (40-50 mmHg) target for mean arterial pressure by the titration of norepinephrine during cardiopulmonary bypass...

OBJECTIVE: To derive and validate an objective definition of postoperative bleeding in neonates and infants undergoing cardiac surgery with cardiopulmonary bypass. METHODS: Using a retrospective cohort of 124 infants and neonates, we included published bleeding definitions and cumulative chest tube output over different postoperative periods (eg, 2, 12, or 24 hours after intensive care unit admission) in a classification and regression tree model to determine chest tube output volumes that were associated with red blood cell transfusions and surgical re-exploration for bleeding in the first 24 hours after intensive care unit admission...

PURPOSE: The vasoactive-inotropic score (VIS) is a scale showing the amount of vasoactive and inotropic support. Recently, it was suggested that the VIS after cardiac surgery predicts morbidity and mortality in infants. The purpose of this study was to evaluate the VIS at the end of surgery as a predictor of morbidity and mortality in adult cardiac surgery. METHODS: A retrospective cohort study of 129 adult cardiac surgery patients was performed at a university hospital...

PURPOSE: Hyperglycemia is a common issue in infants after cardiac surgery for congenital heart disease. Poor glycemic control is suspected to be associated with adverse postoperative outcomes. This study was performed to investigate clinical factors contributing to hyperglycemia in the perioperative period in infats. METHODS: A total of 69 infants (aged 1-12 months) who were admitted to Yokohama City University Hospital Intensive Care Unit (ICU) after surgical repair of congenital heart diseases with cardiopulmonary bypass (CPB) were retrospectively analysed...

Background: When safe to do so, avoiding blood transfusions in cardiac surgery can avoid the risk of transfusion-related infections and other complications while protecting a scarce resource and reducing costs. This protocol describes a kidney substudy of the Transfusion Requirements in Cardiac Surgery III (TRICS-III) trial, a multinational noninferiority randomized controlled trial to determine whether the risk of major clinical outcomes in patients undergoing planned cardiac surgery with cardiopulmonary bypass is no greater with a restrictive versus liberal approach to red blood cell transfusion...

We have recently found that diabetes is associated with the inactivation of the calcium-activated potassium channels (KCa) in endothelial cells, which may contribute to endothelial dysfunction in diabetic patients at baseline. In the current study, we further investigated the effects of diabetes on coronary arteriolar responses to the small (SK) and intermediate (IK) KCa opener NS309 in diabetic and non-diabetic patients and correlated that data with the changes in the SK/IK protein expression/distribution in the setting of cardioplegic ischemia and reperfusion (CP) and cardiopulmonary bypass (CPB)...

Bretschneider (histidine-tryptophan-ketoglutarate) solution with its high histidine concentration (198 mM) is one of many cardioplegic solutions, which are routinely used for cardiac arrest. The aim of this study was to evaluate the physiological biochemical degradation of administered histidine to histamine and its major urinary metabolite N methylimidazole acetic acid. A total number of thirteen consecutive patients scheduled for elective isolated coronary artery bypass grafting with cardiopulmonary bypass were enrolled in the prospective observational designed study at the Department of Thoracic and Cardiovascular Surgery between 04/2016 and 06/2016...

Achieving pediatric cardiac surgery using cardiopulmonary bypass (CPB) without allogeneic blood transfusion is challenging. There are many clinical and economic factors that point to the importance of avoiding blood transfusions. In some instances, honoring patients or parents beliefs may be the reason for avoiding blood transfusions. For example, patients or parents of the Jehovah's Witness faith refuse blood transfusion based on their religious beliefs. Over the last decade, our institution has seen a steady increase in our pediatric Jehovah's Witness patient population...

Blood product usage is a quality outcome for patients undergoing cardiac surgery. To address an increase in blood product usage since the discontinuation of aprotinin, blood conservation strategies were initiated at a tertiary hospital in Oakland, CA. Improving transfusion rates for open heart surgery patients requiring Cardiopulmonary bypass (CPB) involved multiple departments in coordination. Specific changes to conserve blood product usage included advanced CPB technology upgrades, and precise individualized heparin dose response titration assay for heparin and protamine management...

Hemodilution is a common perioperative practice. The deleterious effects of excessive hemodilution and subsequent edema formation have been well documented by numerous authors. Colloid oncotic pressure (COP) is a reliable clinical indicator of hemodilution in cardiac surgery. The intent of this study is to determine if a correlation exists between COP and various patient outcome variables. It would also be helpful to know if there is a particular COP value to avoid preventing or limiting patient morbidity. Blood samples from 61 adult patients (mean age = 70 years old) undergoing cardiopulmonary bypass surgery were collected for COP calculation and comparison...

Utilization of intraoperative autotransfusion (IAT) during cardiac surgery with cardiopulmonary bypass (CPB) has been shown to reduce allogeneic red blood cell transfusion. Previous research has emphasized the benefits of using IAT in the intraoperative period. The present study was designed to evaluate the effects of using IAT on overall hematocrit (Hct) drift between initiation of CPB and the immediate postoperative period. We reviewed 3,225 adult cardiac procedures occurring between February 2016 and January 2017 at 84 hospitals throughout the United States...

During cardiac surgery, myocardial protection is performed using diverse cardioplegic (CP) solutions with and without the presence of blood. New CP formulations extend ischemic intervals but use high-volume, crystalloid-based solutions. The present study evaluated four commonly used CP solutions and their effect on hemodilution during cardiopulmonary bypass (CPB). Records from 16,670 adult patients undergoing cardiac surgery with CPB between February 2016 and January 2017 were reviewed. Patients were classified into one of four groups according to CP type: 4-1 blood to crystalloid (4:1), microplegia (MP), del Nido (DN) and histidine-tryptophan-ketoglutarate (HTK)...

OBJECTIVE: Ultrafiltration (UF) during cardiopulmonary bypass (CPB) is a well-accepted method for hemoconcentration to reduce excess fluid and increase hematocrit, platelet count and plasma constituents. The efficacy of this technique may confer specific benefit to certain patients presenting with acquired cardiac defects. The purpose of this study was to retrospectively evaluate the effect of UF on end-CPB hematocrit by cardiac surgical procedure type. METHODS: A review of 73,506 cardiac procedures from a national registry (SCOPE) was conducted between April 2012 and October 2016 at 197 institutions...

OBJECTIVES: In paediatric cardiac surgery, body weight-adjusted miniaturized cardiopulmonary bypass (CPB) circuits within a comprehensive blood-sparing approach can reduce transfusion requirements. Haemodilution resulting from mixing the patient's blood with a CPB crystalloid solution may be reduced to the extent that asanguineous priming becomes possible. Therefore, we adopted asanguineous priming in our clinical routine. Our goal was to report the effects of asanguineous priming on transfusion requirements, clinical features associated with transfusion and effects on in-hospital morbidity...

Miller-Fisher syndrome (MFS) is an uncommon neurological disorder that is considered a variant of the Guillain-Barre syndrome (GBS). It is clinically defined by a triad of symptoms, namely ataxia, areflexia and ophthalmoplegia. These acute inflammatory polyradiculopathic syndromes can be triggered by viral infections, major surgery, pregnancy or vaccination. While the overall incidence of GBS is 1.2-2.3 per 100 000 per year, MFS is a relatively rare disorder. Only six cases of GBS after cardiac surgery have been reported, and to our knowledge, we describe the first case of MFS after coronary artery bypass surgery...
