The field of pediatric mechanical circulatory support with ventricular assist devices has lagged significantly behind that of adult patients. However, there is increasing attention on the emerging field of pediatric ventricular assist device support. In this review, part of the Pediatric Cardiac Intensive Care Society/Extracorporeal Life Support Organization Joint Consensus Statement on Mechanical Circulatory Support, we discuss several important aspects of pediatric ventricular assist device, focusing on biomechanics and selection of the most appropriate device.

ReviewMedical and nursing care of the child on mechanical circulatory support.
To review the medical and nursing care of children receiving mechanical circulatory support as part of the Pediatric Cardiac Intensive Care Society/Extracorporeal Life Support Organization Joint Statement on Mechanical Circulatory Support. DATA SOURCES/STUDY SELECTION/DATA EXTRACTION/DATA SYNTHESIS: This is a general review of current issues of medical and nursing care of children on mechanical circulatory support. It consists of knowledge gained from practical experience combined with supporting evidence and/or discussion of controversies for which evidence exists or is inconclusive. The scope of this review includes assessment and monitoring, cardiovascular, pulmonary, and renal and fluid management, as well as infection prevention and treatment, neurological, and nutritional considerations. Physical and psychological care is discussed, as well as ethical and practical issues regarding termination of support. ⋯ There are unique aspects to the medical and nursing care of a patient requiring mechanical circulatory support. Preserving the possibility for cardiac recovery when possible and preventing damage to noncardiac organs are essential to maximizing the probability that patients will have quality survival following support with a mechanical circulatory support device.

Comparative Study Clinical TrialA dose-response study of dexmedetomidine administered as the primary sedative in infants following open heart surgery.
To evaluate the dose-response relationship of dexmedetomidine in infants with congenital heart disease postoperative from open heart surgery. ⋯ Dexmedetomidine administration in infants following open heart surgery can provide improved sedation with reduction in supplemental medication requirements, leading to successful extubation while receiving a continuous infusion. The postoperative hemodynamic changes that occur in infants postoperative from open heart surgery are multifactorial. Although dexmedetomidine may play a role in decreasing heart rate immediately postoperative, the changes were not clinically significant and did not fall below postinfusion heart rates.

Multicenter Study Comparative StudyThe ideal time interval for critical care severity-of-illness assessment.
Determine if the shortest sampling interval for laboratory variables used to estimate baseline severity of illness in pediatric critical care is equivalently sensitive across multiple sites without site-specific bias, while accounting for the vast majority of dysfunction compared with the standard 0- to 12-hour Pediatric Risk of Mortality III score. ⋯ Prognostically important laboratory physiologic data collected within the interval from 2 hours prior to PICU to admission through 4 hours after admission account for the vast majority of dysfunction that these variables would contribute to Pediatric Risk of Mortality III scores. There was no institutional bias associated with this sampling period.

ReviewOutcomes following extracorporeal membrane oxygenation in children with cardiac disease.
Extracorporeal membrane oxygenation is a commonly used form of mechanical circulatory support in children with congenital or acquired heart disease and cardiac failure refractory to conventional medical therapies. In children with heart disease who suffer cardiac arrest, extracorporeal membrane oxygenation has been successfully used to provide cardiopulmonary support when conventional resuscitation has failed to establish return of spontaneous circulation. ⋯ Thus, a clear understanding of survival to discharge and long-term functional and neurologic outcomes are essential to guide the use of extracorporeal membrane oxygenation now and in the future. This review, part of the Pediatric Cardiac Intensive Care Society/Extracorporeal Life Support Organization Joint Statement on Mechanical Circulatory Support, summarizes current knowledge on short- and long-term outcomes for extracorporeal membrane oxygenation used to support children with cardiac disease.
