The treatment of pneumopericardium in the newborn infant

Abstract

Pneumopericardium with cardiac tamponade is a life-threatening emergency in the newborn infant. The case fatality rate is high (75% in 41 documented cases in the English literature), and diagnosis often delayed (in 13 of 29 deaths the pneumopericardium was diagnosed postmortem). Treatment is frequently unsatisfactory, and recurrence of the pneumopericardium with tamponade is likely after initial pericardial needle aspiration--an incidence of 53%. A case of pneumopericardium in a critically ill newborn is reported; the details of successful management, using a large bore intrapericardial catheter with continuous drainage, are discussed.
