Background: Symptomatic spontaneous pneumothorax is estimated to occur in 0.05-1% of all term newborn infants. This study was performed to analyze the clinical characteristics of symptomatic spontaneous pneumothorax by distinguishing primary and secondary pneumothorax and the differences between primary and secondary pneumothorax.
Methods: We reviewed the medical records of term newborn infants who were born at Wonkwang University Hospital From January 2000 to June 2007, having respiratory difficulty, being shown pneumothorax in the chest X-ray. The subjects were divided into two groups according to preceding diseases; primary pneumothorax and secondary pneumothorax group, then each clinical characteristics were assessed.
Results: The incidence of symptomatic spontaneous pneumothorax was 0.66%. There were no differences in sex, maternal age, gestational age, delivery mode, Apgar scores, oligohydramios, and renal and cardiac anomaly between primary and secondary pneumothorax. The onset of symptoms was within 6hours after birth in the majority, and there was no difference between primary and secondary pneumothorax. The pneumothorax was more frequent in right side. The most common preceding disease of secondary pneumothorax was respiratory distress syndrome. The treatment performed most commonly was oxygen therapy with chest tube insertion. The mean duration of oxygen therapy was 5.6±3.8 days, and it was longer in secondary pneumothorax than in primary pneumothorax.
Conclusion: In this study, the incidence of symptomatic pneumothorax in term neonate infants was 0.66%, and most of them occurred in 6hours after birth. It occurred more frequently to right side. The major preceding disease of secondary pneumothorax was respiratory distress syndrome. Chest tube insertion and ventilator therapy was needed in most patients, and oxygen therapy was ceased rapidly in primary than secondary pneumothorax.
