The aim of this study was to compare blood flow velocity changes in the middle cerebral artery before, during and after heart surgery with cardiopulmonary bypass for patients with and without postoperative cognitive dysfunction. ⋯ Middle cerebral artery's blood flow velocity was decreased after anaesthesia induction and during cardiopulmonary bypass for patients with postoperative cognitive dysfunction comparing with their blood flow velocity preoperatively. Blood flow velocity during bypass has diagnostic value for postoperative cognitive dysfunction. Brain biomarker glial fibrillary acidic protein is not helpful in diagnosing postoperative cognitive dysfunction.

We aimed to investigate the risk factors affecting survival after extracorporeal membrane oxygenation use in pediatric postcardiotomy patients. ⋯ Parameters affecting mortality after extracorporeal membrane oxygenation support in pediatric postcardiotomy patient group were the presence of a syndrome, multiple runs of extracorporeal membrane oxygenation, and single-ventricular physiology. Timing of extracorporeal membrane oxygenation initiation, appropriate patient selection, appropriate reintervention or reoperation for patients with correctable pathology, the use of an appropriate cannulation strategy in single-ventricle patients, management of shunt flow, and appropriate interventions to reduce the incidence of complications play key roles in improving survival.

The objective of this study was to evaluate the efficacy of protocolized use of catheter-directed thrombolysis and echocardiography in submassive pulmonary embolism patients. ⋯ This retrospective study demonstrates the effectiveness of protocolized use of catheter-directed thrombolysis and echocardiography in reversing severe right heart dysfunction in submassive pulmonary embolism patients.

Studies reporting risk factors associated with unsuccessful weaning for coronary artery bypass grafting patients on venoarterial extracorporeal membrane oxygenation are scarce. This study was designed to identify factors associated with unsuccessful weaning from venoarterial extracorporeal membrane oxygenation. ⋯ Pre-existing hypertension, serum creatinine, serum lactate, and low platelet count were independent predictors for unsuccessful weaning from venoarterial extracorporeal membrane oxygenation in patients undergoing coronary artery bypass grafting.
