“…Radiative heat loss is a major source of energy loss in infants nursed in conventional, convectively heated incubators (1)(2)(3). The magnitude of the radiative heat loss is determined by the difference in temperature between the infant's slun and the surfaces facing the infant, i.e.…”

A radiant hood warmer, a device that heats the incubator roof independently of the incubator's main heat source, was used to study the thermal balance of 11 full term and 13 preterm (gestational age 25-34 weeks) infants exposed to an isolated elevation of incubator roof temperature at stable ambient air temperature and humidity. After initial measurements without active heating of the incubator roof, the hood warmer was set to 33 degrees C, 36 degrees C and finally (preterm infants only) to 39 degrees C. At least 18 min of measurements with the infant asleep were made at each hood warmer setting. In the term infants an increase in roof temperature from 30.5 degrees C to 35.6 degrees C resulted in an increase in skin temperature from 35.4 to 35.9 degrees C, and a decrease in radiative heat loss from 32.8 to 20.7 W/m2 exposed skin. In the preterm infants an increase in roof temperature from 31.0 to 38.4 degrees C led to an increase in skin temperature from 35.7 to 36.3 degrees C and a decrease in radiative heat loss from 34.1 to 13.0 W/m2 exposed skin. The increased inner roof surface temperature did not affect evaporative or convective heat loss, skin blood flow, respiratory water loss, oxygen consumption or transepidermal water loss in either group. Thus, at stable ambient air temperature and humidity, the increase in incubator roof temperature resulted in an increase in skin temperature and a decrease in radiative heat loss in both term and preterm infants.

Sheffield SJO 2THDrs Kohler and Pritchard comment: Mathers and Milner are correct to point out that the term diagnostic accuracy has been used loosely in this paper.'We found that it became very confusing to try to present false positive and false negative data for each type of tumour for each preoperative diagnostic method; Table 2 in our paper evolved as a comprehensible compromise.We have, however, calculated the diagnostic efficiency of ultrasound for neuroblastoma to be 87-4% (and for Wilms' tumour to be 89-3% as shown above). The diagnostic efficiency for intravenous urography for neuroblastoma and Wilms' tumour was 86-2% and 89-4% respectively. This confirms our statement that ultrasound was no more efficient than intravenous urography in the diagnosis of these two tumours.We used the term diagnostic sensitivity only once when quoting directly from a paper which specifically used this term.
