Bloodletting Puncture in the Treatment of Acute Ischemic Stroke

The bloodletting puncture is an external treatment for acute ischemic stroke by releasing an appropriate amount of blood with a three-edged needle at specific points on the patient\'s body. As a special treatment for acute ischemic stroke, it has been used clinically in hospitals of traditional Chinese medicine in China for many years and has achieved certain efficacy. However, there is a lack of comprehensive and objective clinical observation and mechanism research on this treatment method, as well as a lack of scientific efficacy evaluation standards and technical specifications. Therefore, we planned to explore the effectiveness, safety and accessibility of bloodletting puncture in the treatment of acute ischemic stroke through a mixed-method study of a multi-center randomised controlled trial and focus group.
