Algor mois is ?
Correct Answer: Cooling of body
Description: Ans. is 'b' i.e., Cooling of body ALGOR MOIS After death, dead body behaves like an ine substance and therefore, if atmospheric temperature is low, body loses its heat by conduction, covection, radiation and evoporation, so as to attain the atmospheric temperature, i.e. the body cools. No cooling of dead body occurs if atmospheric temperature is higher than that of body. Cooling of body stas 1/2 to 1 hour after death. There are varying opinions about rate of cooling of dead body: i) Most widely accepted view is that the rate of cooling in india (tropical countries) is 0.5-0.7deg C/hour, so that body attains atmospheric temperature in 16-20 hours after death. In temperate climate, the rate of fall is about 1.5deg C/hour. ii) As per another view, cooling is faster in initial period, when the temprature difference between body and atmosphere is maximum ? First 30-45 minutes --> No temperature fall (isothermic phase). First 1-6 hours --4 1.5-2deg C/hour. 6-12 hours 0.9-1.2deg C/hour. After 12 hours ---> 0.4-0.6deg C/hour. iii) Rate of cooling is related to difference in temperature and its surroundings (environment). In the first 2 hours average rate fall of temperature is roughly half this difference. In next 2 hours the temperature fall is at half this rate and in subsequent 2 hours, at quaer this rate. iv) Most common site for recording temperature is the rectum. Thermameter is inseed in rectum around 8-10 cm for 2 minutes. Other sites for recording tempeure are nose, ear (external auditory meatus), vagina and under liver. Medicolegal impoance of algor mois - i) It is a sign of death. ii) Time since death may be determined and and algor mois is the most impoant indicator to determine the time since death during first 24 hours.
