Observational StudyRotational Thromboelastometry Rapidly Predicts Thrombocytopenia and Hypofibrinogenemia During Neonatal Cardiopulmonary Bypass.
Thrombocytopenia and hypofibrinogenemia during neonatal cardiopulmonary bypass (CPB) contribute to bleeding and morbidity. Rotational thromboelastometry (ROTEM) is a viscoelastic assay with a rapid turnaround time. Data validating ROTEM during neonatal cardiac surgery remain limited. This study examined perioperative hemostatic trends in neonates treated with standardized platelet and cryoprecipitate transfusion during CPB. We hypothesized that ROTEM would predict thrombocytopenia, hypofibrinogenemia, and the correction thereof. ⋯ ROTEM analysis during neonatal cardiac surgery is sensitive and specific for thrombocytopenia and hypofibrinogenemia, identifying deficits within 10 minutes. Platelet and cryoprecipitate transfusion during neonatal CPB normalizes platelet count, fibrinogen level, and ROTEM amplitudes.

Observational StudyUbiquitin C-Terminal Hydrolase 1 and Phosphorylated Axonal Neurofilament Heavy Chain in Infants Undergoing Cardiac Surgery: Preliminary Assessment as Potential Biomarkers of Brain Injury.
There are no reliable markers to assess brain injury in neonates following cardiac surgery. We examine ubiquitin C-terminal hydrolase 1 (UCHL1) and phosphorylated axonal neurofilament heavy chain (pNF-H), neuronal-specific biomarkers released following axonal and cortical injury, in neonates undergoing cardiac surgery involving cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA). ⋯ A rapid rise in UCHL1 levels was observed in the DHCA group, suggesting that it may be a marker for acute brain injury. Follow-up with neurodevelopmental studies is ongoing.

Corticosteroids and Other Anti-Inflammatory Strategies in Pediatric Heart Surgery: A National Survey of Practice.
The role of steroids to mitigate the deleterious effects of pediatric cardiopulmonary bypass (CPB) remains a matter of debate; therefore, we aimed to assess preferences in administering corticosteroids (CSs) and the use of other anti-inflammatory strategies in pediatric cardiac surgery. ⋯ We found wide variability in practice in the administration of CSs for pediatric cardiac surgery, both within and between units. While most anesthetists administer CSs in at least some cases, there is no consensus on the type of steroid, the dose, and at which patient groups this should be directed. Modified ultrafiltration is still used by most of the centers. Almost half of consultants use aprotinin, while heparin-coated circuits are infrequently used.

Controversy remains regarding the optimal surgical approach for children with supravalvular aortic stenosis (SVAS). ⋯ Brom aortoplasty promotes restoration of normal aortic root geometry and relief of coronary ostial stenosis, which is important in preventing myocardial ischemia. Computed tomography imaging is our preferred diagnostic modality. Intermediate-term outcomes are excellent with no recurrent SVAS, coronary events, or reoperations on the aortic valve.

ReviewEducation and Training in Pediatric Cardiac Critical Care.
Pediatric cardiac critical care is a new and emerging field. There is no standardization to the current education provided, and high-quality patient outcomes require such standardization. For physicians, this includes fellowship training, specific competencies, and a certification process. ⋯ There is evidence that supports a finding that critical care nursing experience may have a positive impact on outcomes from pediatric cardiac surgery. A rigorous orientation and meaningful continuing education may augment that. For all disciplines and levels of expertise, simulation is a useful modality in the education in pediatric cardiac critical care.
