Hyperthermia -
Ans. is 'd' i.e., Failure of thermoregulationo Hyperthermia is defined as election of core body temperature above the normal diurnal range of 36 to 37.5degC due to failure of thermoregulation at the level of hypothalamus.o Hyperthermia is not synonymous with the more common sign of fever, which is induced by cytokine activation during inflammation, and regulated at the /eve/ of the hypothalamus.o A temperature above 40degC for 104degF) is generally considered to be consistent with severe hyperthermia.Temperature Classification Core (rectal, esophageal, etc.) <35.OdegC(95.O0F)o Hypothermiao Normal36.5-37.5nC (97.7-99.5 DF)o Fever>37.5-38.3degC (99.5-100.9 degF)o Hyperthermia>37.5-38.3degC (99.5-100.9 degF)o Severe Hyperthermia>40.0-41,5degC (104.0-106.7 degF) Complication of HyperthermiaRespiratoryCardiacHypotensionSeizureRhabdomyolysisAcute kidneyDICHepaticfunctiondysfunction injury injuryo Aspirationo Acute dccompen-o Results from oBronchospasmsated heart failureperipheral o ARDSand myocardialvasodilatation oNoncordiogenicinjurycardiac Pulmonaryedemao ST segmentdysfunction and o Pneumonitischanges sinusvolume depletion o Pulmonarytachyarrhythmias infarction o Pulmonary hemorrhage
