A 1-year-old boy breathing via a T-piece system and recovering from me
ningococcal septicaemia in the intensive care unit suffered a severe b
out of coughing and developed bilateral pneumothoraces and tension pne
umopericardium resulting in electromechanical dissociation and asystol
e. Conventional cardiopulmonary resuscitation and adrenaline boluses w
ere unsuccessful. Administration of 20 ml.kg(-1) of colloid and 3 mmol
.kg(-1) of sodium bicarbonate solutions produced instantaneous return
of cardiac output. The deleterious effects of cardiac tamponade appear
ed to decrease with increasing cardiac filling pressures. The patient
was managed conservatively and he made a full recovery with no signs o
f residual neurological deficit.
