NCT05921695

Brief Summary

The goal of this clinical trial is to compare the effect of high chlorine solution such as normal saline and non-high chlorine solution such as sodium lactate ringer's solution on renal function in patients with heat stroke. The main question it aims to answer is whether limiting the amount of normal saline infusion during emergency department can lower the incidence of acute kidney injury and mortality in patients with heat stroke. Participants will receive a free normal saline infusion during the emergency department according to the study design, or a restricted normal saline infusion while using sodium lactate Ringer's instead. Researchers will compare the normal saline infusion group and sodium lactate Ringer's group to see if limiting the amount of normal saline infusion during emergency department can lower the incidence of acute kidney injury and mortality in patients with heat stroke.

Outcome Measures

Primary Outcomes (1)

  • Acute kidney injury

    Acute kidney injury was defined as increase in serum creatinine by 50% within 7 days, or increase in serum creatinine by 0.3 mg/dl (26.5μmol/l) within 2 days, or oliguria

    up to 90 days

Secondary Outcomes (3)

  • Continuous renal replacement therapy

    up to 90 days

  • length of ICU stay

    up to 90 days

  • in-hospital mortality

    up to 90 days

Study Arms (2)

Normal Saline infusion group

ACTIVE COMPARATOR

During the emergency department, the normal saline infusion was not restricted.

Drug: Normal Saline infusion and Ringer lactate infusion

Ringer lactate infusion group

EXPERIMENTAL

Use ringer lactate or other balanced crystallographic solution instead of normal saline. Strictly limit the amount of normal saline infusion. Normal saline will only be infused by medical advice if the patient has hypochloremia or needs saline as solvent.

Drug: Normal Saline infusion and Ringer lactate infusion

Interventions

Normal Saline infusion and Ringer lactate infusionDRUG

The heat stroke patients will be infused with different chlorine concentrations fluid during the emergency department.
