简要总结
TCM is an essential context of the ICH management in Chinese culture. Given the potential benefits of Chinese herbal medicine Zhongfengxingnao formula (ZFXN) in reducing haematoma and bleeding after acute intracerebral hemorrhage (ICH) from fundamental research and small clinical studies, more reliable evidence is required to guide ICH treatment using TCM. This study is designed to evaluate the blinding and physical consistency between the investigational drug and placebo in RCT, taking the trial named Chinese herbal medicine in patients with acute intracerebral hemorrhage (CHAIN) as an example. Therefore the blinding of placebo as well as and physical consistency with investigated TCM in CHAIN trial will be determined. In addition, an assessment method for blinding and physical consistency could be developed for subsequent placebo evaluations.
详细描述
A total of 48 subjects will be divided into two parts for manual scoring, which includes not only the proportion of the discrimination to ZFXN, which is the primary outcome in this study, but also the physical (odor, taste) consistency of the two drugs. The primary outcome was the percentage of ZFXN response. The secondary outcomes included artificial sensory score and intelligent sensory attributes of testing drug.
