HERNANDEZ-BENITEZ, Rodrigo  y  BECERRA-BECERRA, Rosario. Functional echocardiography in the neonatal intensive care unit; experience in a tertiary level hospital. Bol. Med. Hosp. Infant. Mex. [online]. 2016, vol.73, n.5, pp.325-330. ISSN 1665-1146.


The Hospital Infantil de Mexico Federico Gómez is a tertiary level hospital with a neonatal intensive care unit (NICU), which is one of the most important units in the treatment of newborn's diseases in México. In this unit, the decisions are taken based on some clinic parameters such as respiratory rate, heart rate, arterial pressure, urinary output and lactate levels. The functional echocardiography is a useful tool which improves the hemodynamic evaluation and decisions in neonatal care. Data on its use in neonatal units in Mexico is lacking.


A prospective study conducted in NICU patients during 3 months from August to October 2015 at the Hospital Infantil de Mexico Federico Gómez. Gestational age, birth weight, admission criteria, days of life at examination, indication for functional echocardiography and changes in treatment were evaluated and finally, we performed a new study 24 hours later. Echocardiographic evaluation included: assessment of presence/hemodynamic significance of PDA; myocardial function: ejection fraction/shortening fraction, left ventricular output, right ventricular output, systemic blood flow; and signs of pulmonary hypertension.


30 echocardiographic studies were performed in 15 patients. The average age was 9.6 days, the variability in gestational ages were 37 to 42 weeks; the average weight was 2.583 kg. The most frequent diagnosis was respiratory distress, and the principal indications for echocardiography were hemodynamic instability and sepsis (53.3%).

In 11 cases (73.3%), the treatment was modified posteriorly to functional echocardiography, and in 10 cases we observed improvements in the 24 hours after control.


Functional echocardiography is a useful tool in NICU, which may assist with clinical decision-making.
