急诊气管插管患者插管后不同时间口腔牙菌斑及细菌变化分析

目的分析急诊气管插管患者插管后不同时间口腔牙菌斑、细菌变化情况及其相关因素。方法选取急诊就诊并行气管插管患者64例,在插管后即刻及6、8、10、12h分别进行牙菌斑评分和牙菌斑采样细菌培养。结果急诊气管插管后不同时间点牙菌斑及牙菌斑细菌培养评分比较,差异有统计学意义(均P0.01)。手术、居住地与牙菌斑及牙菌斑细菌培养评分有相关性,有吸烟史与牙菌斑评分显著负相关(均P0.05)。结论急诊气管插管后患者口腔牙菌斑评分及细菌数量随着插管时间的延长而升高,插管后即刻至6h变化程度最为显著,其次为6~8h;手术患者、有吸烟史和居住在农村的患者口腔护理时间可适当提前。

Change pattern of dental plaque and bacteria in the mouth after patients receiving emergency tracheal intubation

Objective To observe the change pattern of dental plaque and bacteria in the mouth after patients receiving emergency tracheal intubation and to analyze the risk factors. Methods Sixty-four patients receiving emergency tracheal intubation were enrolled, then dental plaque score was assessed and sampling of plaque for bacterial culture was done in the same teeth, immediately after intubation and at 6, 8, 10, 12 h after intubation. Results The dental plaque score and the growth of bacteria showed statistical differences at different time points （P〈0.01 for both）. Surgery and types of residence （urban or rural area） were correlated with the dental plaque score and the growth of bacteria, and smoking history was negatively correlated with the dental plaque score （P〈 0.05 for all）. Conclusion The dental plaque score and the growth of bacteria in plaque increase with time after emergency tracheal intubation, with the highest increase occurring in the first 6 h, then in the next 2 h. The start time for oral care should be as early as possible for patients receiving surgery, with smoking history, and living in rural area.
