摘要 目的探讨心血管手术患者术前牙菌斑与术后肺部感染的关系,以及影响牙菌斑的相关因素。方法对211例心血管手术患者术前牙菌斑进行检测;调查患者一般情况、缺牙数、手术时间、机械通气时间、并发症等;分析牙菌斑的可能影响因素及与术后发生肺部感染的关系。结果患者术前菌斑指数(PLI)为1.3~4.8分,平均(3.2±0.8)分,其中≥3.0分141例,占66.8%。与术前PLI<3.0分的患者相比较,术前PLI≥3.0分的患者术后肺部感染发生率较高,P=0.022。患者术前PLI,男性高于女性,P=0.039;年龄45~59岁组及≥60岁组PLI均高于低年龄组,P<0.001;高级学历组低于其他低学历组,P<0.001;有合并症组高于无合并症组,P=0.018。此外,患者术前PLI与缺牙数呈正相关,相关系数r=0.432,P<0.001。结论术前PLI较高的心血管手术患者,术后肺部感染发生率较高;性别、年龄、受教育程度及有无合并症是影响术前牙菌斑的相关因素。
