Sample size:

干预措施:

实验组患者首先由微导管跨越闭塞血管段,造影提示位于真腔后,冰箱中取出冷藏4℃生理盐水,2min内抽取50ml完成,以10ml/min的推注速度5min。推注完成之后进行常规取栓操作,具体取栓器械及取栓步骤由研究者自行决定。在取栓手术完成后(无论是否达到2b/3级再通),再次取出生理盐水,2min内抽取300ml在置于颈内动脉的中间导管或指引导管内以30ml/min的速度推注10min。推注完成后原则上不建议再次进行采用室温下造影剂的脑血管造影以稀释局部温度。(如术后未能完成再通,则常规经指引导管或中间导管给予第二步亚低温处理) (如出现术中并发症或其他未能进行亚低温处理而结束手术的情况,则退出研究)

干预措施代码:

Intervention:

In the treatment group, the microcatheter was first used to cross the occlusion vascular segment. After the angiography indicated that it was located in the true cavity, the normal saline was removed from the refrigerator at 4℃, and 50 mL was extracted within 2 minutes, and the injection rate was 10ml/min for 5 minutes. Routine thrombectomy was performed after injection, and the specific thrombectomy instruments and procedures were determined by the investigator. After the thrombectomy was completed (whether mTICI 2b/3 was achieved or not), the normal saline was removed again, and 300 mL was extracted within 2min and injected into the intermediate catheter or digital guide tube placed in the internal carotid artery at a rate of 30ml/min for 10min. In principle, it is not recommended to repeat cerebral angiography with contrast media at room temperature to dilute local temperature after injection. (If recalculation was not completed after surgery, a second step of mild hypothermia was routinely administered via a guide catheter or an intermediate catheter.) (If intraoperative complications occurred or other conditions ended the surgery without mild hypothermia, the study was withdrawn)
