摘要
目的:观察不同方法采样培养对下呼吸道感染病原学诊断价值。方法:采用支气管肺泡灌洗液(BALF)细菌定量培养,并与保护标本刷(PSB) 和痰培养进行比较。结果:感染组16 例患者21 例次采样,BALF 法19次阳性(≥105cfu/ml) ,PSB法15 例次阳性(≥103 cfu/ml),两种方法所获菌株一致率为72.4% (21/29),定量培养结果相关程度好(r=0 .807 ,P< 0.001) 。非感染组20 例,BALF法3 例阳性,PSB法1 例阳性。BALF法和PSB法特异性分别为85-0 % 和95-0% ,敏感性分别为90-5 % 和71-4% ,两种方法的敏感性和特异性无统计学差异。痰标本分别与BALF和PSB标本培养结果比较,需氧菌株一致率分别为33-3% (24/72)和23-6 %(17/72)。结论:BALF细菌定量培养与PSB方法对下呼吸道感染的病原菌诊断具有相同的诊断价值,且操作简便安全。
