Cost of living for infants weighing 1,000 grams or less at birth.

This article reports the in-hospital cost of caring for 75 infants weighing 1,000 gm or less at birth who were born during the 2 1/2-year period between January 1973 and June 1975. Thirty infants (40%) survived. Nineteen of 27 infants tested (70%) appear to be neurologically and developmentally "normal" at 1 to 3 years of age. Hospital charges were adjusted to September 1976 rates and corrected for a 94% collection rate. Physicians' fees represented less than 5% of the total bill and were not included. The average adjusted daily and total costs for the 45 infants who died were $825 and $14,236, respectively. The average adjusted daily and total costs for the 30 survivors were $450 and $40,287, respectively. The average adjusted total cost per "normal" survivor was $88,058. It is our belief that the outcome justifies this expense. Society, however, must be the ultimate judge.

Neonatal thermography.

Anterior and posterior view thermograms were recorded in 37 neonates. Studies were performed under a radiant heater servocontrolled to an abdominal skin temperature of 36.0 C. Heart, liver, and kidneys, being highly vascular structures, were detected as "warm" areas on the body surface. A longitudinal study of an infant with a patent ductus arteriosus and congestive heart failure deomnstrated a generally cooler chest following a decrease in pulmonary artery blood flow accomplished by ductal ligation. Another infant demonstrated a unilateral warm area posteriorly over the left flank. At autopsy the right kidney and its vasculature internal organs. Thermography may prove to be a simple noninvasive tool for routine screening in the neonate of highly vascular internal organs. Thermographic detection of renal malformation may offer considerable potential.

Ammonia accumulation in platelet concentrates during storage.

Newly prepared platelet concentrates (PC) and platelet poor plasma (PPP) stored at either room temperature (RT) or 4 C were analyzed for ammonia content initially, and after storage at 24, 48, and 72 hours. These studies demonstrate that ammonia rapidly accumulates in PC stored at RT. This accumulation appears to be temperature dependent, as evidenced by the observed differences in ammonia accumulation in PC stored at 4 C and RT. Whether ammonia acts as a toxic metabolite in the inhibition of platelet function and the development of the "storage lesion," which occurs in PC stored at RT, needs further clarification. Additional studies are also necessary to establish the clinical efficacy of transfusing ammonia-containing platelet concentrates into premature neonates with immature functioning livers, and perhaps into adults with severe liver disease.
