The most common type of ventilation leading to
pneumothorax was Inspiratory Positive Pressure
Ventilation (IPPV) in 62.7% and Continuous
All these newborns were examined for the predisposing factors leading to ventilation such as respiratory distress syndrome, meconium aspiration syndrome, pneumonia and birth asphyxia. Other variables like sex, term vs. preterm delivery, unilateral vs. bilateral pneumothorax, birth weight, respiratory management including ventilator settings and mortality rate after pneumothorax were recorded by a general practitioner. The neonates having pneumothorax before ventilation or with malposition of tracheal tube were excluded from the study. All analyses were performed with SPSS15. Statistical significance was set at P
