Acute respiratory disorders in the newborn: a survey at the Mt. Hope Women's Hospital, Trinidad

RESUMO

This retrospective study was undertaken to determine the incidence of acute respiratory disorders (ARD) in newborns delivered at the Mount Hope Women's Hospital [MHWH] from January 1st to December 31st, 1994. The study also examined the relationships between incidence rates and maternal and neonatal parameters. Hyaline membrane disease (HMD)m trabsuebt tachypnea of the newborn (TTN), meconium aspiration syndrome (MAS), persistent foetal circulation (PFC) and pulmonary infection (PI) were identified as ARDs among 5,062 live newborns using standard diagnostic criteria. Overall, 174/5,062 neonates were diagnosed with ARD to give an incidence of 3.4 percent (104 males and 70 females). The commonest ARD was PI (39 percent) followed by HMD (48/4363) in full term neonates. HMD occurred mainly in the preterm and low birth weight babies. TTN and PI were found in all gestational age groups. Asphyxia was present in 9.8 percent (17/174) at 1 minute and in 10.9 percent (19/174) at 5 minutes. It was more common in babies who developed HMD and PFC. Forty one percent of babies with ARD required assisted ventilation. There were 58 (33 percent) deaths. More than one half of those ventilated died (55 percent), 2/3 of those with asphyxia at both 1 and 5 minutes of age. There was significantly greater mortality among neonates with HMD as compared to the other ARDs.
