研究目的:

对心脏手术患者数据进行多因素分析,并借助经脾动脉多普勒血流阻力指数验证心脏手术患者术后感染预测模型。探索经脑-脾轴传导的脾神经交感兴奋情况导致术后感染的可能,识别出更具有特征的术后感染危险因素,有利于围术期制定有效的干预措施来预防此类患者出现术后感染从而使患者受益。  

Objectives of Study:

By conducting a multifactorial analysis of post-operative cardiac patients and utilizing the splenic artery Doppler flow resistance index, we established a predictive model for post-operative infection. We investigated the potential of splenic nerve sympathetic excitation through the brain-spleen axis to cause post-operative infection, identified more characteristic risk factors for post-operative infection, and facilitated the development of effective intervention strategies to prevent such infections and benefit patients during the perioperative period.
