Objetivo

Conocer la variabilidad de la práctica clínica habitual en la prevención y el tratamiento de la inmadurez pulmonar.

Pacientes y métodos

Estudio transversal dentro de un estudio en 13 países europeos. De todos los neonatos de muy bajo peso nacidos en los centros colaboradores se recogieron datos de las historias clínicas sin ningún tipo de instrumentación adicional.

Resultados

La encuesta fue remitida a 213 centros, de los cuales contestaron 72 (34 %), con un total de 162.157 nacimientos (40 % del total en 1999). El 8% de los recién nacidos eran de bajo peso, el 1,2 % de muy bajo peso (2.015) y el 0,45% de extremado bajo peso. El 52,5 % de los de muy bajo peso recibieron al menos una dosis de corticoides prenatales, el 28,8%, un ciclo completo, y el 9,3%, más de un ciclo. Todos los centros utilizan algún preparado surfactante, y cuentan con un protocolo escrito el 76,8 %. El 41 % de los recién nacidos de muy bajo peso fueron intubados al nacer, el 47,6 % precisaron ventilación mecánica durante más de 6 h y el 5% presión positiva continua. El 80,4% de centros usaban corticoides posnatales, la mitad para la prevención de enfermedad pulmonar crónica (EPC) y el 83,4 % como de terapéutica. La pauta más habitual era indicarlos a los 7-14 días de vida, durante 3-9 días. Entre la morbilidad neonatal destaca la EPC (14 %), conducto arterioso sintomático (16,7 %), hemorragia intraventricular (8,5 %) y enterocolitis necrosante (7,3 %).

Conclusiones

La tasa de exposición a corticoides prenatales fue baja y la práctica de repetir los ciclos y el empleo de corticoides posnatales para prevenir la EPC elevadas. Sigue siendo preciso difundir la reciente evidencia científica sobre el uso de corticoides prenatales y posnatales

Objective

To determine clinical practice variability in the prevention and postnatal treatment of lung immaturity in Spain

Patients and methods

Cross-sectional study within a larger study in 13 European countries. Data were obtained from the medical records of all very low birth weight (VLBW) infants born in participating centers, without other instrumentation.

Results

A questionnaire was sent to 213 centers. Seventy-two (34 %) responded, with 162,157 births (40 % of total births in 1999). Eight percent of infants were of low birth weight, 1.2% (2,015) of very low birth weight and 0.45 % were of extremely low birth weight. A total of 52.2% of VLBW infants received at least one dose of prenatal steroids, 28.8% received a full course and 9.3 % received more than one cycle. All centres used surfactant and 76.8 % had a written protocol. Forty-one percent of VLBW infants were intubated, 47.6% required mechanical ventilation for more than 6 hours, and 5% underwent continuous positive airway pressure. A total of 80.4 % used postnatal steroids, half of them for chronic lung disease prevention, and 83.4 % used steroids to treat this disease. Steroids were most frequently indicated at 7-14 days of life for 3-9 days. The most important causes of neonatal morbidity were chronic lung disease in 14 %, ductus arteriosus in 16.7 %, intraventricular hemorrhage in 8.5 %, and necrotizing enterocolitis in 7.3%.

Conclusions

Prenatal exposure to steroids was low. Repeat cycles and postnatal steroid use to prevent chronic lung disease was high. Recent scientific evidence on the use of pre- and postnatal steroids should be more widely disseminated.
