Tension pneumopericardium following tracheoplasty for congenital tracheal stenosis.

Tension pneumopericardium is a rare complication of mechanical ventilation following tracheoplasty for congenital tracheal stenosis. This case report describes fatal tension pneumopericardium in a three-month-old male infant some 24 hours following tracheoplasty for this condition. Because of persisting stenosis of the left main bronchus, ventilation pressures of PIP 23 cm H2O and PEEP 5 cm, progressing to PIP 28 cm and PEEP 7 cm were needed to maintain adequate respiratory exchange. Partial relief of the pneumopericardium was achieved by vigorous cardiac massage, but three days later the infant died of massive airway haemorrhage.
