Hyperthermia treatment and prevention

Treatment of hyperthermia consisting of measures which will rapidly lower core body temperature. However, care must be taken to avoid causing vasoconstriction or shivering. Vasoconstriction will impede heat loss and shivering will create heat.

Once heat stroke has developed, the prognosis is poor, particularly with advanced age. The treatment goal is to reduce tissue damage by lowering the temperature of vital structures such as the brain, heart and liver. Tissue damage ensues when core temperature reaches 109F (43C). Cooling treatments can be internal or external.

Internal cooling techniques such as ice water gastric or rectal lavage, extracorporeal blood cooling, and peritoneal or thoracic lavage are effective but they are also difficult to manage and associated with complications.

External cooling techniques are usually easier to implement, well tolerated and effective.

Hyperthermia is a condition that is much better prevented than treated in an elderly person. Elderly patients should be cautioned about the dangers of hot weather. For those elders at very high risk, such as those living alone without air conditioning or ventilation, temporary relocation to a more protected environment such as a shelter or community center should be implemented. Nurses can suggest several specific strategies that can help elderly people avoid hyperthermia during heat waves.

These strategies include:

In a severe and prolonged heat wave, elderly people who live alone without air conditioning or appropriate ventilation may require assistance to temporarily relocate to safer quarters.
