المستخلص Introduction: Preterm neonates are highly susceptible to pneumothorax either spontaneous or secondary to underlying pathology. Seasonal variations of pneumothorax was previously reported which gave attention to evaluate this condition in preterm neonates. Aim of Work: To evaluate the effect of seasonal variation on incidence of pneumothorax among neonates, and to describe the clinical characteristics, management, and outcomes of neonates with pneumothorax. Patients and Methods: This cross-sectional longitudinal study was conducted on 169 neonates who were admitted at NICU of Children Hospital, Cairo University to estimate the incidence of pneumothorax in preterm neonates and its seasonal variation. Results: 95.90% had secondary pneumothorax, mostly in the right side (59.8%), mostly of moderate severity (66.30%). Seasonal variations of pneumothorax among the studied neoantes; 36.1% were in spring, 29.6% were in winter, 17.8% were in autumn, and 16.6% were in summer. Mortality represented 59.80% of the included neonates, but it was significantly related to lower gestational age, and the need for mechanical ventilation but not to seasonal variation of pneumothorax. Conclusion: Incidence of pneumothorax may be related to caesarean section, lower gestational age, use of mechanical ventilation and RDS was the commonest underlying lung disease. Mortality was high due to lower birth weight, decreased gestational age, weight, length, head circumference, haemoglobin and platelets. Seasonal variation of pneumothorax among preterm neonates was obvious especially in Spring and Winter but this variation was not related to mortality among preterm neonates. |
