Abstract
Survival after repair of congenital diaphragmatic hernia (CDH) is limited by adequacy of prenatal pulmonary development. Ventilatory function may be compromised further by multiple adverse perinatal factors that necessitate intermittent pressure ventilation (IPPV). Barotrauma frequently complicates IPPV, and is observed in several forms. These complications lead to ventilatory and hemodynamic dysfunctions. Of 50 infants with CDH repaired in the first 24 hr of life, 36% survived. Infants operated in the first 8 hr had a lower survival rate (28%) than those operated between 8 and 24 hr (50%). Tension extrapulmonary air (TEPA) was observed in 30 infants (60%), was significantly higher in dying infants ( p p
