A premature 18-hour-old newborn is intubated and
mechanically
ventilated because of progressive respiratory
distress. Labor was complicated
by maternal fever and increased leukocyte count;
membranes ruptured 36
hours before delivery. His blood pressure and urine
output have
decreased since birth. The newborn appears acutely
ill, and peripheral pulses
are not palpable; the skin is pale, cool, and mottled.
The liver edge
is palpable 4 cm below the right costal margin. His
leukocyte count is
5000/mm3, platelet count is 48,000/mm3, and partial
thromboplastin time
is 60 sec. An x-ray film of the chest shows diffuse,
bilateral,
interstitial infiltrates.
