[FUNCTIONAL ECHO IN PRETERM INFANTS - PAST, PRESENT AND FUTURE]

The use of point of care ultrasound to assess cardiovascular function performed by a neonatologist who is not a cardiologist, is gaining interest in the neonatal intensive care unit (NICU). Clinical signs such as heart rate, blood pressure and capillary refill time provide limited insight into the adequacy of systemic blood flow and organ perfusion. Functional echocardiography (echo) enables real time evaluation of cardiac performance, identifying the nature of cardiovascular compromise, guiding therapeutic decisions and monitoring response to treatment. Application of functional echo in the NICU includes assessment of patent ductus arteriosus (PDA), pulmonary hypertension, shock and placement of umbilical catheters. There is evidence implicating that functional echo alters neonatal treatment and may improve outcome. Functional echo does not aim to replace the detailed structural assessments provided by consultative services of pediatric cardiologists. Close collaboration with pediatric cardiology is essential. In the past two years there is an increasing awareness for using functional echocardiography by neonatologists in Israel. Three conferences and an educational workshop were held in Israel with world renowned lecturers. Protocols defining how the exam should be performed were prepared, and agreement was reached with pediatric cardiologists on how to implement the use of functional echo by neonatologists, with the intention to create a distinct group of neonatologists with knowledge and skills in functional echo and a profound understanding of cardiac and respiratory physiology and hemodynamics.
