There’s a popular myth circulating online that pricking the fingertips to let out blood can serve as first aid for someone experiencing a sudden stroke. Is this method reliable? The answer is no. Strokes are broadly categorized into ischemic (caused by a blockage) and hemorrhagic (caused by bleeding), and in either case, the most critical action is getting the patient to a hospital as quickly as possible to receive timely treatment. The practice of ‘bloodletting from the fingertips’ lacks scientific evidence and may delay proper medical care or even lead to infection or worsened outcomes. Medical experts emphasize that if stroke symptoms—such as sudden facial drooping, slurred speech, or weakness on one side of the body—are observed, emergency services should be called immediately. The patient should be kept lying flat with their head turned to one side; do not give them water or medication, and absolutely avoid any form of self-administered bloodletting. Effective stroke management relies on rapid professional evaluation, including imaging tests, followed by appropriate interventions like thrombolysis or mechanical thrombectomy. Therefore, the idea of using fingertip bloodletting to treat stroke is an unproven folk remedy that should never replace evidence-based medical care.
网络上流传一种说法：突发脑卒中（俗称中风）时，立即在患者十指指尖放血可以急救。这种做法真的靠谱吗？答案是否定的。脑卒中分为缺血性（脑梗死）和出血性（脑出血）两大类，无论哪种类型，关键在于尽快送医、争取黄金救治时间。所谓“放手指血”不仅缺乏科学依据，还可能延误治疗，甚至造成感染或加重病情。医学专家明确指出，一旦发现疑似中风症状（如突然口角歪斜、言语不清、一侧肢体无力等），应立即拨打急救电话，保持患者平卧、头偏向一侧，避免喂水或乱服药物，切勿自行放血。正确的急救方式是争分夺秒送医，由专业医生进行影像学检查后决定溶栓、取栓或其他治疗方案。因此，“放手指血救中风”属于民间偏方，不可轻信，更不能替代正规医疗。
