目的研究肺结核患者痰液液化后再用消毒剂消毒的效果。方法以胰酶为消化剂对肺结核患者痰液进行液化后分别加入常用含氯消毒液、石炭酸溶液和煤酚皂溶液进行消毒处理,接种培养基观察结果并与对照组比较。结果对照组3种消毒剂消毒2 h后结核杆菌培养阳性率分别为79%、91%、93%,试验组3种消毒剂消毒2 h后结核杆菌培养全部为阴性。结论胰酶预处理能促进消毒剂对痰液中结核杆菌的杀灭作用。
Objective To study the disinfection effect of disinfectant after sputum liquefaction in patients with pulmonary tuberculosis. Methods The sputum of patients with pulmonary tuberculosis was liquefied with trypsin as digestive reagent, and then disinfected with commonly used chlorine-containing disinfectant, carbolic acid solution and coal-phenol soap solution respectively. The inoculation medium was observed and compared with the control group. Results The positive rates of Mycobacterium tuberculosis culture in the control group were 79%, 91% and 93%, respectively, after being disinfected for 3 hours. The test group was disinfected for 2 hours and the Mycobacterium tuberculosis culture was negative. Conclusion Pretreatment with trypsin can promote the killing effect of disinfectant on Mycobacterium tuberculosis in sputum.
