ABSTRACT
OBJECTIVE: To evaluate surfactant production and function in term neonates with transient tachypnea of the newborn (TTN). STUDY DESIGN: Samples of gastric aspirates collected within 30 minutes of birth from 42 term newborns with gestational age ≥ 37 weeks (21 patients with TTN and 21 control subjects), delivered via elective cesarean delivery, were analyzed with lamellar body count and stable microbubble test. RESULTS: Results of lamellar body counts and stable microbubble tests were significantly lower in the TTN group than in control subjects (P = .004 and .013, respectively). Lamellar body counts were significantly lower in infants with TTN requiring oxygen for ≥ 24 hours after birth than in infants requiring oxygen for < 24 hours (P = .029). When the cutoff point was 48 hours, the stable microbubble count was significantly lower in the group requiring oxygen for ≥ 48 hours than in the group requiring oxygen for < 48 hours (P = .047). CONCLUSIONS: Term infants with TTN had low lamellar body counts associated with decreased surfactant function, suggesting that prolonged disease is associated with surfactant abnormalities.

Entre 40-50 por ciento de los casos con síndrome de dificultad respiratoria (SDR) evolucionan como una Taquipnea Transitoria (TTRN). Se realizó un estudio retrospectivo descriptivo, con el objetivo de conocer el comportamiento de la (TTRN) en la Unidad de Cuidados Especiales de Neonatología (UCEN) del Hospital General Docente Ciro Redondo García, en el período comprendido enero 2008 hasta diciembre 2009. El universo fue 113 recién nacidos (RN) con SDR y 72 constituyeron la muestra con diagnóstico de (TTRN) por un muestreo no probabilístico. Se confeccionó un formulario y se recogieron variables relacionadas con el parto y examen físico del RN. Los datos se procesaron estadísticamente por el sistema Excel. Aproximadamente 3 de cada 4 RN con (TT) nacen por cesárea, a término, del sexo masculino, normopesos, conteo de apgar normal y tiempo de evolución inferior a 120 horas. Se concluye que el comportamiento de la TTRN en nuestro servicio resultó elevado(AU)
Among 40-50 percent of the cases with syndrome of breathing (SDR) they evolve like a transitory Taquipnea (TTRN). He/She was carried out a descriptive retrospective study, whith the objective of knowing the behaviour of the TTRN in the Unit of Special Cares of Neonatology (UCEN) of the educational general Hospital Ciro Redondo García, in the Period understood January 2008 until December 2009. The universe was 113 new born (RN) with SDR and 72 constituted the simple with diagnostic of TTRN for a sampling non probabilistic. A form was made and variables related with the childbirth and physical exam of the RN were picked up. The data were processed statistically by the system Excel. Approximately 3 of each 4 RN with (TT) they are born for caesarean operation, to term, of the masculine sex, norm weight, count of normal apgar and time of inferiority evolution at 120 hours. You conclude that the behaviour of the TTRN in our service is high(AU)
