Study design:

Cohort study 

研究目的:

本研究想要探讨口腔中卟啉单胞菌属的DNA拷贝数与术后谵妄的关系,以此来提高对术后谵妄发病机制的理解,从而制定针对性的防治措施,减少术后谵妄的发生率,以改善手术患者的生活质量。  

Objectives of Study:

This study aims to explore the relationship between the DNA copy number of Porphyromonas species in the oral cavity and postoperative delirium, in order to enhance the understanding of the pathogenesis of postoperative delirium, thereby formulating targeted prevention and treatment measures, reducing the incidence of postoperative delirium, and improving the quality of life of surgical patients.
