RESUMO

Introduction: It is still controversy about the usefulness of functional echocardiography (FnEC) in critically ill neonates. Objective: To analyze the usefulness of the FnEC in the treatment decisions in neonates admitted to a Neonatal Intensive Care Unit (NICU). Materials and methods: A year prospective study in a NICU. A trained cardiologist performed a FnEC to 72 h of life patients to evaluate the cardiac function and heart structure. We analyzed the clinical decisions after the findings. Results: 37 neonates underwent two FnEC: at the diagnosis and at follow-up. Eleven patients (29.7%) had structural and functional abnormalities, 9 (24.3%) only functional, 7 (18.9%) only structural, and in the rest, 10 (27%), were normal. Al least one change in the management occurred in 70% of the patients. The main changes were to the ventilatory support (63%), followed by inotropic support (19.5%) and fluid intake (10.8%). In all changes, we observed an improvement in the clinical conditions of the neonates. Conclusions: The FnEC allowed to determinate the cardiovascular structures and hemodynamic conditions of the patients and make a more precise therapeutic modifications.


Introducción: Aún existe controversia sobre la utilidad de la ecocardiografía funcional (EcoFn) en la valoración cardiovascular de neonatos críticamente enfermos. Objetivo: Analizar la utilidad de la EcoFn en la modificación de tratamiento en neonatos ingresados a una Unidad de Cuidados Intensivos Neonatales (UCIN). Material y métodos: Estudio prospectivo en una UCIN durante un año mediante EcoFn realizada por un cardiólogo capacitado en pacientes en sus primeras 72 horas de vida extrauterina, con valoración de la funcionalidad cardiaca y presencia de alteraciones estructurales. Con base en los hallazgos se analizaron las modificaciones al tratamiento. Resultados: 37 neonatos fueron evaluados con EcoFn en dos ocasiones: una diagnóstica y otra de seguimiento. En 11 (29.7%) se encontró daño estructural y funcional, en 9 (24.3%) solo funcional, en 7 (18.9%) solo estructural y en 10 (27%) no se observaron alteraciones. En el 70% se realizó al menos un cambio de tratamiento. Los cambios más frecuentes fueron modificaciones al apoyo ventilatorio (63%), seguido del apoyo aminérgico (19.5%) y modificaciones en el aporte de líquidos (10.8%). En todos los casos los cambios mejoraron las condiciones clínicas de los neonatos. Conclusiones: La EcoFn permitió determinar mejor las condiciones estructurales y hemodinámicas de los pacientes y realizar modificaciones terapéuticas más precisas.

RESUMO

BACKGROUND: Gastroesophageal reflux occurs frequently in newborns. A relationship has been suspected between reflux and apnea of prematurity. The objective of this study is to determine this relationship, owing to the fact that premature newborns have immaturity of structures, especially esophageal smooth muscle. METHODS: We conducted a longitudinal, analytical, comparative, and observational case/control study. The study was carried out at the Neonatal Intensive Care Unit and in the Gastrointestinal Physiology Department of the Hospital Español (Mexico City) between January 2002 and December 2004. RESULTS: We included 22 patients: 11 females and 11 males. Mean age was 17.8 ± 8.4 days. Premature newborns represented 72.72% (n = 16). Mean gestational age was 33.1 ± 4.18 weeks. All cases were suspicious for central apnea except for three patients with a mixed cause of apnea. All were submitted to a 24-h pHmetry and a simultaneous polysomnography. Polysomnography was positive in 59% (n = 13) and pHmetry was positive in 50% (n = 11). Prematurity had a strong positive relation with central apnea of the newborn (odds ratio: 15 (p = 0.0154)). Odds ratio for association of central apnea and gastroesophageal reflux was 3.2 (p = 0.2037). CONCLUSIONS: We demonstrate that central apnea in the premature newborn is not a cause of gastroesophageal reflux. However, these patients are more likely to have gastroesophageal reflux in the first days of extrauterine life. It is recommended to exclude pathological gastroesophageal reflux when the newborn presents a clinical scenario compatible with central apnea.
