This document discusses heat stroke and hypothermia. Heat stroke is caused by a high body temperature from excessive heat production, environmental heat absorption, or deficient heat loss. It is characterized by a temperature above normal, increased heart rate and breathing, lack of sweating, and thirst. Left untreated it can cause organ dysfunction, convulsions, and death. Treatment involves cooling the body with ice water and fluids, along with medications. Hypothermia is caused by insufficient heat production and excessive heat loss, leading to subnormal body temperature and symptoms like cold skin and lethargy. Treatment focuses on warming the body with heated rooms and fluids along with medications in severe cases.

3.  Remarkable increase in body temperature
 Due to
 Excessive heat production / misbalancing of body
thermostat
 Absorption of environmental heat
 Deficient of heat loss
 Synonym : Heat Stroke
 Condition of tropic and sub-tropic areas

4.  Is purely environmental
 Metabolic condition
 Due to
 High temp and humidity

5.  Exertion
 Dehydration
 Electrolyte imbalance
 Decrease in sweating when humidity is >60%

6.  Temperature above normal values

7.  Heart rate increase
 Respiration increase
 Absence of sweating
 Increase thirst
 If prolonged
 Renal and liver dysfunction
 Convulsion
 Collapse  death

8.  Ice cold water bath (head, neck and
body)
 Ice cold water for drinking
 IV fluid dextrose / normal saline
 Anti pyretic drug (dipyrone /
panadol )
 Broad spectrum antibiotic

10.  Decrease in body temperature then normal value
 Due to
 Insufficient heat production
 Excessive heat loss

11.  Metabolic condition  decrease muscular activity
 Damage to thermoregulatory center
 Diarrhea
 Over sedation / anesthesia

12.  Sub-normal body temperature
 Cold skin and extremities
 Weak pulse / decrease heart rate
 Shallow breathing
 Lethargy
 terminal stage :- low cardiac output, decrease reflexes
, coma  death

13.  Pre- heated room / shed
 Pre-warmed I/V fluid
 Steroid  shock condition
 Oxygen therapy

15.  Reduce effects of disease
 Taking medicine
 To kill the microbes
 Antibiotic / antiviral / antiprotozoal / antifungal

16.  To promote health
 To preserve health
 To restore health when its impaired
 To minimize suffering and distress
