ReviewFluid Management: Pharmacologic and Renal Replacement Therapies.
Focusing on critically ill children with cardiac disease, we will review common causes of fluid perturbations, clinical recognition, and strategies to minimize and treat fluid-related complications. ⋯ Meticulous fluid management is vital in critically ill children with cardiac disease. Fluid therapy is important to maintain adequate blood volume and perfusion pressure in order to support cardiac output, tissue perfusion, and oxygen delivery. However, fluid overload and acute kidney injury are common and are associated with increased morbidity and mortality. Understanding the etiologies for disturbances in volume status and the pathophysiology surrounding those conditions is crucial for providing optimal care.

ReviewVentricular Assist Devices in Pediatric Cardiac Intensive Care.
The objectives of this review are to discuss the process of patient and mechanical device selection, operative management, and postoperative care with a focus on the management of right ventricular failure, anticoagulation strategies, device-related infections and neurologic sequelae. ⋯ The number of patients with advanced heart failure due to either acquired or congenital heart disease continues to increase, necessitating in some mechanical circulatory support and in others cardiac transplantation. With a limited cardiac donor pool, mechanical circulatory support is playing a greater role in the management of this population. The perioperative morbidity associated with mechanical circulatory support has lessened with improved postoperative management strategies.

This review will focus on the pharmacokinetics (with an emphasis on the context-sensitive half-time), pharmacodynamics, and hemodynamic characteristics of the most commonly used sedative/hypnotic, analgesic, and IV anesthetics used in cardiac intensive care. In addition, the assessment of pain and agitation and withdrawal will be reviewed. ⋯ Children in the cardiac ICU often require one or more components of general anesthesia: analgesia, amnesia (sedation and hypnosis), and muscle relaxation to facilitate mechanical ventilation, to manage postoperative pain, to perform necessary procedures, and to alleviate fear and anxiety. Furthermore, these same children are often vulnerable to hemodynamic instability due to unique underlying physiologic vulnerabilities. An assessment of hemodynamic goals, postoperative procedures to be performed, physiologic vulnerabilities, and the intended duration of mechanical ventilation should be made. Based on this assessment, the optimal selection of sedatives, analgesics, and if necessary, muscle relaxants can then be made.

ReviewExtracorporeal Membrane Oxygenation for Cardiac Indications in Children.
The objectives of this review are to discuss the use of extracorporeal membrane oxygenation following surgery for congenital heart disease, myocarditis and as a bridge to cardiac transplantation. In addition, the latest in circuit equipment, the management of anticoagulation and blood transfusions, and short- and long-term outcomes are reviewed. ⋯ The use of extracorporeal membrane oxygenation to support children with heart disease is increasing. There is wide variability in the use and management of extracorporeal membrane oxygenation between centers. Many areas of extracorporeal membrane oxygenation management warrant additional research to inform clinical practice and improve patient outcomes, including the use of extracorporeal membrane oxygenation in patients undergoing single ventricle palliation, optimizing strategies for monitoring and titrating anticoagulation therapies, and efforts directed at minimizing the risk of neurologic injury.

ReviewNutrition and Mesenteric Issues in Pediatric Cardiac Critical Care.
The objectives of this review are to discuss the challenges of delivering adequate nutrition to children with congenital heart disease, including pre- and postoperative factors and the role of enteral and parenteral nutrition, as well as the evidence supporting current practices. ⋯ Providing adequate nutritional support is paramount for critically ill infants with congenital heart disease, a population at particular risk for malnutrition. Improved nutritional support has been associated with increased survival and reduction in overall morbidity. Further gains can be achieved by creating a clinical culture that emphasizes optimal perioperative nutritional support. Additional research is required to identify the specific nutrient composition, optimal mode, and timing of delivery to maximize clinical benefit.
