Brief Summary

Heat stroke is a life-threatening clinical syndrome characterized by an imbalance between heat production and heat dissipation in the body, resulting from exposure to hot and humid environments and/or strenuous exercise. It is defined by an elevated core temperature exceeding 40°C and central nervous system abnormalities, accompanied by multi-organ dysfunction. The severity of cellular and tissue damage in heat stroke patients depends on the peak temperature reached and the duration of hyperthermia. Rapid reduction of core temperature can halt cellular damage, quickly reverse organ dysfunction, and improve patient outcomes. Therefore, early identification and rapid cooling are crucial to prevent irreversible damage and death in heat stroke patients. However, there is a lack of systematic and specific protocols to guide emergency medical staff in the standardized and effective management of body temperature in heat stroke patients. To address this, our research team previously developed an early in-hospital temperature management protocol for heat stroke patients based on the best available evidence, expert consultations, and expert panel meetings. This study aims to validate the feasibility and effectiveness of the protocol through clinical research, providing a basis for clinical practice.

Outcome Measures

Primary Outcomes (2)

  • cooling rate at 0.5 hours

    The cooling rate at 0.5 hours was calculated in reference to initial body temperature and body temperature at 0.5 hours

    0.5 hours

  • Body temperature at 0.5 hours

    Body temperature at 0.5 hour refers to a reading obtained 25 to 35 minutes after admission.

    0.5 hours

Secondary Outcomes (4)

  • Body temperature at 2 hours

    2 hours

  • in-hospital mortality

    30 days

  • 3-month mortality rate

    3 months

  • Number of participants with other complications

Study Arms (2)

experimental group

EXPERIMENTAL

Using the early in-hospital temperature management protocol for heat stroke patients developed in our previous research, we will implement early identification, rapid cooling, and precise target temperature management for this group of patients.

Other: the early in-hospital temperature management protocol for heat stroke patients

control group

NO INTERVENTION

We will retrospectively collect data on heat stroke patients who were visited before the implementation of the early in-hospital temperature management protocol between 2021 and 2022, meaning this group of patients received temperature management according to the original methods used by their respective hospitals.

Interventions

The early in-hospital temperature management protocol for heat stroke includes early identification, selection of cooling methods for rapid cooling, precise target temperature management, and dynamic monitoring. Effective temperature management will be implemented for heat stroke patients to improve their outcomes.
