目的探讨ICU住院患者痰标本质量控制的临床意义。方法 ICU下呼吸道感染患者1027例痰标本分为干预组487例(A组,痰标本质量综合干预)和未干预组540例(B组),监测两组痰标本合格率、培养阳性率及不同来源痰标本质量。结果 A组痰标本合格率和培养阳性率均高于B组(47.84%vs.36.48%和62.66%vs.36.04%)(P<0.01)。A组气管导管内痰标本合格率及气管套管内痰标本合格率、培养阳性率及细菌半定量≥()比例均高于B组(P<0.05或P<0.01)。结论 ICU住院患者痰标本质量控制综合干预可提高痰标本合格率和培养阳性率。
Objective To investigate the clinical significance of sputum specimen quality control in hospitalized patients with ICU. Methods 1027 sputum samples from patients with lower respiratory tract infection in ICU were divided into intervention group (487 cases) (group A, comprehensive intervention of sputum sample quality) and 540 cases (group B) without intervention group. The sputum samples were tested for the pass rate, Source sputum specimen mass. Results The passing rate and the positive rate of culture in group A were higher than those in group B (47.84% vs 36.48% and 62.66% vs 36.04%, respectively) (P <0.01). A group of endotracheal tube sputum specimens pass rate and tracheal tube sputum specimens pass rate, the positive rate of culture and bacterial semiquantitative ≥ () ratio were higher than the B group (P <0.05 or P <0.01). Conclusion ICU inpatients sputum samples quality control comprehensive intervention can improve the sputum specimen pass rate and culture positive rate.
