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.
