Randomized Controlled Trial
Phosphorylcholine-coated circuits improve preservation of platelet count and reduce expression of proinflammatory cytokines in CABG: a prospective randomized trial.
The interaction of blood with foreign artificial surfaces during cardiopulmonary bypass (CPB) has been recognized as a major stimulus in evoking a systemic inflammatory and metabolic response. Phosphorylcholine (PC) is a new-generation coating material designed to ameliorate biocompatibility and thereby to reduce the detrimental interactions of CPB. We studied the effects of PC-coated perfusion circuits on platelet function and the humoral and cellular response to CPB. ⋯ Despite similar clinical outcome, the obvious reduction of cytokine expression and improved preservation of platelet count suggest superior biocompatibility of PC-coated circuits.

Thromboelastography-based transfusion algorithm reduces blood product use after elective CABG: a prospective randomized study.
Bleeding and allogeneic transfusion remain constant problems in cardiac surgical procedures. In this study, we aimed to test the role of a routine thromboelastography (TEG)-based algorithm on bleeding and transfusions in patients undergoing elective coronary artery bypass grafting (CABG). ⋯ Our results show that routine use of a kTEG-guided algorithm reduces the consumption of blood products in patients undergoing elective CABG. Adopting such an algorithm into routine management of these patients may help to improve clinical outcome and reduce the potential risks of transfusion-related complications and total costs after CABG.

Influence of methylprednisolone on levels of neuron-specific enolase in cardiac surgery: a corticosteroid derivative to decrease possible neuronal damage.
Cerebral injury is a well-known complication after cardiac surgery with cardiopulmonary bypass (CPB), especially in adult patients. Specific biochemical markers like neuron-specific enolase (NSE) and S-100beta protein were developed previously for early detecting neuronal damage after CPB. Corticosteroids are shown to reduce multisystemic deleterious effects of cardiopulmonary bypass due to their anti-inflammatory characteristics. The aim of this study is to demonstrate the decrease of serum neuron-specific enolase levels in patients who received corticosteroids before CPB. ⋯ The lower levels of NSE in patients who received methylprednisolone may suggest that corticosteroids might be useful in decreasing possible neuronal damage during heart surgery. However, we were not able to demonstrate an adverse neurological outcome.

Surgical options for infants with hypoplastic left heart syndrome (HLHS) and/or its variants are cardiac transplantation or the heart-preserving staged palliation with Norwood operation,followed by a two-staged Fontan procedure. We describe our 17-year experience with staged palliation of HLHS and/or its variants. ⋯ This report identified an outcome improvement after staged palliation of HLHS, attributed to an increase in experience and expertise gained over time. Lower operative weight, ascending aortic size, prolonged duration of cardiopulmonary bypass, and hypothermic circulatory arrest were identified to significantly influence early mortality after the Norwood procedure.

Early tracheal extubation is a common goal after cardiac surgery and may improve postoperative outcomes. Our study evaluates the impact of a quality improvement program (QIP) on early extubation, pulmonary complications, and resource utilization after cardiac surgery. ⋯ QIP and early tracheal extubation reduce pulmonary complications and resource utilization after cardiac surgery.
