ReviewCommon endocrine issues in the pediatric intensive care unit.
Thyroid hormone is central to normal development and metabolism. Abnormalities in thyroid function in North America often arise from autoimmune diseases, but they rarely present as critical illness. Severe deficiency or excess of thyroid hormone both represent life-threatening disease, which must be treated expeditiously and thoroughly. Such deficiencies must be considered, because presentation may be nonspecific.

Sepsis remains an important challenge in pediatric critical care medicine. This review provides an appraisal of adjunctive therapies for sepsis and highlights opportunities for meeting selected challenges in the field. ⋯ Potential adjunctive therapies such as corticosteroids, hemofiltration, hemoadsorption, and plasmapheresis may have important roles, but still require formal and more rigorous testing by way of clinical trials. Finally, the design of future clinical trials should consider novel approaches for stratifying outcome risks as a means of improving the risk-to-benefit ratio of experimental therapies.

ReviewAnemia and transfusion in critically ill pediatric patients: a review of etiology, management, and outcomes.
This article describes the incidence and etiology of anemia in critically ill children. In addition, the article details the pathophysiology and clinical ramifications of anemia in this population. The use of transfused packed red blood cells as a therapy for anemia in critically ill patients is also discussed, including the indications for and complications associated with this practice as well as potential reasons for these complications. Finally, the article lists some therapeutic practices that may lessen the risks associated with transfusion, and briefly discusses the use of blood substitutes.

Postoperative care of cardiac patients requires a comprehensive and multidisciplinary approach to critically ill patients with cardiac disease whose care requires a clear understanding of cardiovascular physiology. When a patient fails to progress along the projected course or decompensates acutely, prompt evaluation with bedside assessment, laboratory evaluation, and echocardiography is essential. When things do not add up, cardiac catheterization must be seriously considered. With continued advancements in the field of neonatal and pediatric postoperative cardiac care, continued improvements in overall outcomes for this specialized population are anticipated.

Ethically charged situations are common in pediatric critical care. Most situations can be managed with minimal controversy within the medical team or between the team and patients/families. Familiarity with institutional resources, such as hospital ethics committees, and national guidelines, such as publications from the American Academy of Pediatrics, American Medical Association, or Society of Critical Care Medicine, are an essential part of the toolkit of any intensivist. Open discussion with colleagues and within the multidisciplinary team can also ensure that when difficult situations arise, they are addressed in a proactive, evidence-based, and collegial manner.
