The objectives of this review are to discuss the clinical assessment, pathophysiology, and management of shock, with an emphasis on circulatory physiology, cardiopulmonary interactions, and pharmacologic strategies to optimize systemic oxygen delivery. These principles will then be applied to the clinical syndromes of heart failure and cardiogenic shock that are seen in children. ⋯ An understanding of essential circulatory physiology and the pathophysiology of shock are necessary for managing patients at risk for or in a state of shock. A timely and accurate assessment of cardiac function, cardiac output, and tissue oxygenation and the means by which to enhance the relationship between oxygen delivery and consumption are essential in order to optimize outcomes.

Multicenter Study Observational StudyFactors Associated With Continuous Low-Dose Heparin Infusion for Central Venous Catheter Patency in Critically Ill Children Worldwide.
To identify patient, hospital, and central venous catheter factors that may influence the use of low-dose heparin infusion for central venous catheter patency in critically ill children. ⋯ Patient, central venous catheter, and hospital factors are associated with the use of low-dose heparin infusion in critically ill children. Further study is needed to evaluate the efficacy and persistence of low-dose heparin infusion use.

The objectives of this review are to discuss the anatomy, pathophysiology, surgical repair, and perioperative management strategies for tetralogy of Fallot and its variants. ⋯ Significant refinements have been made in the repair strategy for tetralogy of Fallot, based on improved understanding of postrepair physiology. Important considerations for timing and technique of surgery and perioperative management have been presented, and continued evolution is expected. Expanded use of the pulmonary valve reconstruction technique outlined herein, whatever the age of repair, may improve long-term outcome.

In this review, we will discuss risk factors for developing sepsis; the role of biomarkers in establishing an early diagnosis, in monitoring therapeutic efficacy, in stratification, and for the identification of sepsis endotypes; and the pathophysiology and management of severe sepsis and septic shock, with an emphasis on the impact of sepsis on cardiovascular function. ⋯ There is a lot of excitement in the field of sepsis research today. Scientific advances in the diagnosis and clinical staging of sepsis, as well as a personalized approach to the treatment of sepsis, offer tremendous promise for the future. However, at the same time, it is also evident that sepsis mortality has not improved enough, even with progress in our understanding of the molecular pathophysiology of sepsis.

The objectives of this review are to describe the education and critical thinking skills that characterize pediatric critical care nursing and how these skills impact patient care and outcomes in pediatric cardiac critical care. ⋯ Pediatric cardiac critical care nurses manage complex and vulnerable patients requiring various levels of support. Effective care of these patients requires knowledge about the complex anatomy and physiology associated with congenital and acquired heart disease, as well as the effects of mechanical ventilation, mechanical circulatory support, and vasoactive medications. Strong physical examination skills, accurate interpretation of hemodynamic and laboratory data, active participation in bedside rounds, excellent communication skills, meticulous care of invasive monitoring catheters and tubes, and compassionate support of families are among the skills that distinguish a cardiac critical care nurse.
