Procedure: Temperature control at 33-34 °C In the hypothermia group, patients receiving ECPR will be immediately cooled to 33ºC-34ºC with ECMO using a heat exchanger. After reaching this targeted temperature, the maintenance phase will start, and the target temperature will be kept at 33ºC-34°C. The maintenance phase will end 24 h after reaching this targeted temperature. Subsequently, rewarming to 36ºC-37ºC will be conducted in 24 h. After the rewarming, the temperature will be kept in the range of 36ºC-37.5ºC for 24 h after rewarming or until the end of ECMO, and should not exceed 37.5ºC. Other interventions, such as sedation, administration of neuromuscular blocking agents, antipyretics, and catecholamines, as well as mechanical circulatory support, are optional and performed at the patient's discretion.

Procedure: Temperature control at 36 °C In the normothermia group receiving ECPR, the temperature of 36ºC will be immediately reached with ECMO using a heat exchanger. After reaching this targeted temperature, the maintenance phase will start, and the target temperature will be maintained at 36ºC. The maintenance phase will end 24 h after reaching this targeted temperature. Then, rewarming to 36ºC-37ºC will be conducted in 24 h. After the rewarming, the temperature will be kept in the range of 36ºC-37.5ºC for 24 h after rewarming or until the end of ECMO, and should not exceed 37.5ºC. Other interventions, such as sedation, administration of neuromuscular blocking agents, antipyretics, and catecholamines, as well as mechanical circulatory support, are optional and performed at the patient's discretion.
