两份痰标本代替三份痰标本涂片法的可行性研究

目的 探讨在可疑肺结核病例中能否用两份痰标本涂片法代替三份痰标本涂片法.方法 对1002例可疑肺结核病例的三份痰标本(即时痰、夜间痰、清晨痰)分别进行直接涂片、萋-尼尔逊氏抗酸染色和光学显微镜镜检.结果 即时痰+夜间痰+清晨痰组与夜间痰+清晨痰组的结核阳性率无显著性差异.结论 即时痰不能提高结核阳性率,在可疑肺结核患者中可以用夜间痰+清晨痰两份标本涂片法代替原方案即时痰+夜间痰+清晨痰的三份标本涂片法.

The feasibility study of two sputum specimens instead of three copies of sputum specimens smear method

Objective To explore the possibility of replacing three copies of sputum specimens smear method with two in the suspected tuberculosis cases.Methods The instant sputum specimens,night sputum specimens and early morning sputum specimens which came from 1002 suspected tuberculosis cases were smeared directly,dyed with Ziehl-Neelsin anti-acid dyeing method,and observed with the microscope.Results The positive rates of acid-fast bacillus had no significant differences between the group of instant sputum+night sputum+morning sputum and the group of night sputum+morning sputum.Conclusions Instant sputum cannot improve the positive rates of acid-fast bacillus.The suspicious tuberculosis patients can use two sputum specimens(night sputum+early morning sputum) smear method to replace the original plan of three sputum specimens(instant sputum+night sputum+early morning sputum) smear method.
