简要总结
The evaluation uses ΔHb as an independent factor combined with artificial intelligence (AI) to predict its impact on the prognosis and blood transfusion of patients undergoing cardiac surgery, thereby guiding perioperative clinical blood use and improving patient prognosis.
详细描述
- Select 8 hospitals to form a multi-center team, and enter the keyword "mitral valve replacement" in the case system of 8 hospitals to collect information on 2000 heart surgery patients.
- Mainly collect information on preoperative, intraoperative and postoperative test indexes (blood routine, liver and kidney function, coagulation function, blood gas), cardiac color Doppler, blood transfusion and prognosis of patients undergoing cardiac surgery, using statistical methods for analysis. Identify key observations.
- Gradually incorporate and exclude data, and use statistical methods to conduct preliminary analysis on the collected data.
The AI prediction model was established by machine learning algorithm to predict intraoperative blood transfusion, verify the specificity and sensitivity of the blood transfusion prediction model, and scientifically guide clinical blood use.
