Heat Stroke:Treatment & Interventions
• ABC’s – must stabilize– What assessments/interventions will you perform
initially?
• What do you think the goal of treatment is?
• How would you achieve this goal?
![Page 11: Nursing Care & Interdisciplinary Roles with Adult Clients in the Emergency/Disaster Environment Kelle Howard, MSN, RN, CNE Revised Fall 2012.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649e425503460f94b346a1/html5/thumbnails/11.jpg)
Heat Stroke:Treatment & Interventions

• To what temperature?– Prevent shivering
• Attainment:– Remove clothes, wet sheets, large fan (evaporative), ICE water bath
(conductive), cool IV fluids
– Would you use antipyretics?

Hypothermia:Pathophysiology
• Definition– Core temperature less than 95˚F (35˚C)• Core temp <86˚F - severe hypothermia• Core temp <78˚F - death
– Heat produced by the body cannot compensate for cold temps of environment
– 55%-60% of all body heat is lost as radiant energy• Head, thorax, lungs
Dec body temp peripheral vasoconstriction shivering & movement coma results <78˚F

Case Study: Extra InfoChildren’s Health Encyclopedia
• 0-4 years old --- pools implicated in 60-90% of drowning– also bathtubs
• Teen boys --- natural bodies of water• Roughly 4 out of 5 drowning victims are male• Death or permanent neurological damage is very likely when patients arrive at the
emergency room comatose or without a heartbeat. • Of these patients, 35 to 60 percent die in the emergency department• Almost all of those who survive have permanent disabilities. • Early rescue of near-drowning victims (within five minutes of submersion) and
prompt CPR (within less than ten minutes of submersion) seem to be the best guarantees of a complete recovery
• Extremely cold water (less than 41°F or 5°C) seems to protect individuals from some of the neurological damage that occurs with near drowning. Some hypothermic near-drowning victims have been revived after they appeared dead and have experienced few permanent disabilities.
