Eight very low-birth-weight premature infants (mean birth weight 1.11 ± 0.05 [SEM] kg, mean gestation 30 ± 1 weeks, and mean age 9 ± 2 days) were studied under servocontrolled radiant warmers with and without a loosely fitted, transparent, and flexible Saran plastic blanket. Metabolic rate was significantly less in all infants when covered by the blanket (oxygen consumption was 7.99 ± 1.13 mL/kg/min v 9.00 ± 1.10 mL/kg/min uncovered, P < .001). There were also significant reductions in insensible water loss (1.86 ± 0.18 v 1.25 ± 0.20 mL/kg/h, P < .01) and in heat demand from the radiant warmer (14.3 ± 1.3 v 9.9 ± 1.4 mW/cm2, P < .001) when infants were nursed under the blanket compared with the control condition, respectively. Covering the critically ill, very low-birth-weight infant nursed under a radiant heater with a thin, transparent layer of Saran is beneficial in reducing oxygen consumption, insensible water loss, and the need for exposure to high levels of radiant heat. Further investigation to confirm the benefits and possible complications of plastic blankets should be conducted before routine use can be recommended.

A mathematical model of heat balance in human infants suggests that it may be possible for severe hyperthermia to develop if an infant is unable to remove his blankets in response to overheating (thermal entrapment). This hypothesis was tested in an animal model of weanling piglets. Ten piglets were warmed in a radiant heater to rectal temperature of 41 degrees C to simulate a fever. Animals in the experimental and control groups were removed from the heater and covered with ordinary infant blankets (to a thickness of approximately 3 cm). Endogenously produced heat caused the animals to warm to 42 degrees C. At this point, the control animals were uncovered. They rapidly cooled to normal body temperature. Animals in the experimental group remained covered until they expired from hyperthermia at 43.9 +/- 0.7 degrees C (SD) after 96 +/- 43 (SD) min. These data show that lethal hyperthermia may result from thermal entrapment. This finding may help clarify the role that hyperthermia may play in illnesses such as hemorrhagic shock and encephalopathy syndrome and some cases of sudden infant death syndrome.

Normal Utilization

As the city develops radiady, the natural gas is widely used nealy in every filed of people’s lives. During the pressure regulation, the phenomenon of ice jam, which can affect the normal utilization, happens. Heater can be regarded as one of the most important measures that prevents pipe from freezing occurring due to temperature drop caused by pressure regulation. Low-temperature radiant heater with tight structure is specifically designed for gad gate station. The heat transfer process of the gate station is analyzed. In the meantime, the mathematical model of radiant heater, which could be fitted for the gate station, is erected. At the same time, the influence of heat exchange size, radiant panel size and radiant efficiency, brought by tube are discussed. The result shows that the tube type of radiant heater has a greatest performance. Considering the tubes with compact structure, taking tube type of radiant heater as the heater used in gate station is the optimal decision. The analysis combined in this paper is the foundation to choose the heater of gate station.

The rate of water evaporation from diapers was determined by sequential weights of open and closed regular diapers and of open superabsorbent diapers in three different environments—radiant heater at 100% heater output, radiant heater at 50% heater output, and room air. In all three environments, evaporation was greatest with open regular diapers, less with open superabsorbent diapers, and least with closed regular diapers. Evaporation was greatest under the radiant heater with 100% heater output, less under the radiant heater with 50% heater output, and least in room air. An open, regular diaper under 100% heater output lost 45% of its water after one hour and 85% had evaporated after two hours. Smaller volumes of water demonstrated a larger percentage of evaporation than larger volumes. Recommendations are made for the use of(1) either open, superabsorbent diapers or closed, regular diapers, (2) prompt weights after urination, and (3) accurate and precise scales.

This paper describes a newly developed nonlinear computer program that predicts internal reaction forces and motions of a multiline marine production riser exposed to wave and current forces. The paper also presents an analytical method that accounts for large geometric displacements and nonlinear wave forces. A simulation of the response of a prototype articulated multiline marine production riser during a mild tropical storm illustrates the program’s capability.
