NCT05779176

Brief Summary

Therapeutic hypothermia (TH) in stroke has demonstrated robust neuroprotection in animals especially after ischemia-reperfusion injury, but its safety and efficacy remain controversial. The investigators propose this trial to study the clinical and radiological effects of therapeutic hypothermia in acute ischemic stroke patients treated with intravascular thrombectomy (IVT).

Outcome Measures

Primary Outcomes (1)

  • Neurological function prognosis

    the score on the modified Rankin Scale, seven grades ranked from 0 to 6, higher scores mean worse outcome

    90±14 days post-operation

Secondary Outcomes (8)

  • Ratio of mRS score 2 or less

    90±14 days post-operation

  • Incidence of intracranial hemorrhage and symptomatic intracranial hemorrhage

    24-72 hours post-operation

  • Target vascular recanalization rate

    24-72 hours post-operation

  • NIHSS score

    7 days post-operation

  • Final infarct volume

    7 days post-operation

  • +3 more secondary outcomes

Study Arms (2)

Normothermia arm

NO INTERVENTION

Patients randomized to normothermia will be maintained at 36-37°C during the entire study period.

Therapeutic hypothermia arm

EXPERIMENTAL

Patients assigned to TH will receive intravascular temperature management to achieve the target temperature of 34-35 °C

Procedure: Therapeutic hypothermia

Interventions

The study intervention is therapeutic hypothermia. After intubation, patients assigned to therapeutic hypothermia will receive central venous catheterization through right jugular vein or femoral vein depending on the cooling application and the unique needs, a flexible catheter will be inserted and iced saline was circulated through the multiple balloons of the catheter in a closed-loop design to induce therapeutic hypothermia. This system also has a hydrophilic coating with heparin and a triple-lumen central venous catheter to satisfy the need of fluid or drug infusion, blood draw and central venous pressure monitoring. After central venous catheterization, patients assigned to TH will receive intravascular temperature management to achieve the target temperature of 34-35 °C.
