Of the 97 children in the hypothermia group and the 93 children in the control group, death or an IQ score below 70 occurred in 46 (47%) and 58 (62%), respectively (P=0.06); death occurred in 27 (28%) and 41 (44%) (P=0.04); and death or severe disability occurred in 38 (41%) and 53 (60%) (P=0.03). The CoolCap study gathered data using the ...
Convection-cooling is sometimes loosely assumed to be described by Newton's law of cooling. [6] Newton's law states that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings while under the effects of a breeze. The constant of proportionality is the heat transfer coefficient. [7]
Several studies have shown that for uncovered infants, lined hats significantly reduce heat loss and thermal stress. [54] [55] [56] Children have a larger surface area per unit mass, and other things being equal should have one more layer of clothing than adults in similar conditions, and the time they spend in cold environments should be ...
However, treatment with oral salbutamol, a drug that stimulates the beta-2 adrenergic receptor, [20] greatly reduced these symptoms within 48 hours. [31] In a subsequent study of 16 individuals with FARIS aged less than 4 weeks, 4 full weeks, 10 weeks, and 6 months to 17 years, oral salbutamol caused symptom improvements in 13 (81.3%) with all ...
The statement of Newton's law used in the heat transfer literature puts into mathematics the idea that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings. For a temperature-independent heat transfer coefficient, the statement is:
A child exhibiting any signs of heat illness should be taken into air conditioning or shade immediately and be sprayed or given compresses of lukewarm or cool water, experts say. Emergency ...
Neonatal encephalopathy (NE), previously known as neonatal hypoxic-ischemic encephalopathy (neonatal HIE or NHIE), is defined as a encephalopathy syndrome with signs and symptoms of abnormal neurological function, in the first few days of life in an infant born after 35 weeks of gestation.
An early stage of hyperthermia can be "heat exhaustion" (or "heat prostration" or "heat stress"), whose symptoms can include heavy sweating, rapid breathing and a fast, weak pulse. If the condition progresses to heat stroke, then hot, dry skin is typical [ 2 ] as blood vessels dilate in an attempt to increase heat loss.
