Abstract: Objective To explore the clinical effects of using bronchoscope to inject drug in the location and high frequent electro-cut method for bronchial tuberculosis(BTB).Methods Ninety-seven BTB patients who were diagnosed and on standard treated were randomly divided into 3 groups,and were combined with the treatment with bronchoscope intervention of drug injection and high frequent electro-cut.Efficacy was assessed and followed up after treatment.Results In the high frequent electro-cut group,the caseous necrotic mass and acestoma in the bronchi were cleaned away through the bronchoscope high frequency electric,and injected INH and gentamycin.This group’s average treatment frequency was 1.8 times and the total effective rate was 97.7%.In the local injection group,INH and gentamycin were used to lavage the focus locally after bronchial secretion was cleaned by bronchoscope.The average treatment frequency was 9.1 times and the total effective rate was 88.5%.The Control group’s effective rate was 55.5% which was only used the standard anti-TB treatment.Concluction BTB is easily to be miss in the diagnosis,and the treatment outcome of the standard anti-TB treatment was poor.However,the bronchoscope intervention of drug injection and high frequent electro-cut are more inexpensive,faster,more effective and safer.
