本文报导了34例次慢性支气管炎患者进行支气管肺泡灌洗液细菌定量培养结果,其中急性发作期20例、临床缓解期14例;还有10例对照组的结果。20例慢支急性发作期病人中,17例病人共培养出定量值≥1×10~5cfu/ml的致病菌25株,这些细菌浓度平均为10~(5.66±0.52)cfu/ml显著高于临床缓解期10~(3.19±0.81)cfu/ml(p<0.01)。和对照组10~(2.27±0.78)cfu/ml(p<0.01)。说明支气管肺泡灌洗液细菌定量培养法能较准确地分离出引起慢支急性发作的病原菌。
In this paper, 34 cases of chronic bronchitis patients with bronchoalveolar lavage fluid bacterial quantitative culture results, including 20 cases of acute exacerbations, clinical remission in 14 cases; there are 10 cases of control group results. Among the 20 patients with acute exacerbation of chronic bronchitis, 25 of them were co-cultured with 17 patients with the quantitative value ≥1 × 10 ~ 5cfu / ml. The average concentration of these bacteria was 10 ~ (5.66 ± 0.52) cfu / ml In clinical remission 10 ~ (3.19 ± 0.81) cfu / ml (p <0.01). And control group 10 ~ (2.27 ± 0.78) cfu / ml (p <0.01). Bacteria bronchoalveolar lavage fluid quantitative culture method can be more accurately isolated from the chronic bronchitis caused by acute pathogens.
