Symptoms and prevention of Heat stroke

Heat stroke is a form of  hyperthermia in which the body temperature is elevated dramatically.  body temperature is   greater than 40.6 °C (105.1 °F) due to environmental heat exposure with lack of  thermo regulation. The most important measures to prevent heat strokes are to avoid becoming dehydrated and to avoid vigorous physical activities in hot and humid weather.Heat stroke is a medical emergency and can be fatal if not promptly and properly treated.

 Symptoms and Sign of heat stroke

Symptoms of heat stroke can sometimes similar to those of  heart attack  or other conditions. Sometimes a person experiences symptoms of heat exhaustion before progressing to heat strokes. common symptoms include…

1) nausea

2) vomiting

3) fatigue

4) weakness

5) headache

6) muscle cramps, aches

7) dizziness

8) high body temperature

9) absence of sweating, hot red flushed dry skin

10) rapid pulse

11) difficulty in breathing

12) strange behavior

13) hallucinations

14) confusion

15) agitation

16) disorientation

17) seizure

18) coma

Infants and children are also at risk. In particular, infants or young children who are unattended in locked cars may suffer heat-related illness quickly, since the indoor temperature of a locked care can rise to dangerous levels even in moderate weather and infants  died of heat stroke

Prevention of heat stroke

  • Go to shady area, remove clothing, apply cool water to the skin.
  •  person is able to drink liquids, cool water or other cool beverages that do not contain alcohol or caffeine.
  • Monitor body temperature with a thermometer and continue cooling efforts until the body temperature drops to 101 to 102 F (38.3 to 38.8 C).
  • avoid vigorous physical activities in hot and humid weather.
  • Take frequent breaks to hydrate yourself. Wear hats and light-colored, lightweight, loose clothes.
  • Keep cars locked when not in use and never, ever, leave infants or children unattended in a locked car
  •                                                   Treatment of heat stroke
    •                                                                        Treatment involves rapid mechanical cooling.The body temperature must be lowered immediately. The patient should be moved to a cool area (indoors, or at least in the shade) and clothing removed to promote heat loss .   The person is bathed in cool water or a hypothermia vest can be applied. However, wrapping the patient in wet towels or clothes can actually act as insulation and increase the body temperature. Cold compresses to the foot , head, neck, and groin will help in cooling.. Fan or dehumidifying Air conditioners may be used to aid in evaporation of the waterImmersing a patient into a bathtub of cool (but not cold) water (immersion method) is a recognized method of cooling. This method requires the effort of 4-5 people and the patient should be monitored carefully during the treatment process. Immersion should be avoided for an unconscious patient, the patient’s head must be held above waterHydration is of paramount importance in cooling the patient. This is achieved by drinking water (oral rehydration) Intravenous hydration (via a drip) is necessary if the patient is confused, unconscious, or unable to tolerate oral fluids.

      Alcohol rubs will cause further dehydration and impairment of consciousness and should be avoided The patient’s heart rate and breathing should be monitored.
