Hypothermia

Area of Science:

• Critical Care Medicine
• Environmental Health
• Emergency Medicine

Background:

• Accidental hypothermia involves unintentional core temperature decline below 35°C.
• Patients at risk are diverse, with stressors including environmental exposure and underlying conditions.
• Physiological responses fail as core temperature drops, necessitating therapeutic intervention.

Purpose of the Study:

• To emphasize the critical need for understanding pathophysiological variables in hypothermia rewarming.
• To identify indications for active rewarming techniques in critical care settings.
• To highlight the challenges in predicting patient outcomes due to misleading clinical signs.

Main Methods:

• Review of pathophysiological variables affecting rewarming strategies.
• Analysis of factors influencing cardiovascular resuscitation and rewarming technique selection.
• Identification of clinical indicators mandating active rewarming interventions.

Main Results:

• No definitive randomized controlled trials establish ideal rewarming strategies for all presentations.
• Active rewarming is indicated by poikilothermia, failure to rewarm, cardiovascular instability, and other factors.
• Simultaneous or sequential use of rewarming techniques offers a versatile therapeutic approach.

Conclusions:

• Understanding cold's effect on coagulation is vital for resuscitation and rewarming.
• Active rewarming is essential for specific patient presentations in critical care.
• Predicting outcomes is challenging due to the unreliability of traditional prognostic indicators.
