To observe the curative effect of ultrasonic atomizing inhalation of Jiedu Huatan tang for cough due to primary lung cancer，and to analyze the nursing points.Methods：A total of 116 cases of patients with cough due to primary lung cancer were divided into the control group and the observation group according to the random number table method，58 cases in each group.The control group was given oral administration of codeine phosphate tablets，and the observation group was additionally treated with ultrasonic atomizing inhalation of Jiedu Huatan tang based on the treatment of the control group.Both groups were given corresponding nursing interventions for ten days continuously.The scores of cough，cough in Visual Analogue Scale(VAS)and Cough Quality-of-Life Questionnaire(CQLQ)before and after treatment in the two groups were compared； the onset time of relieving cough，the remission time and disappearance time of cough were recorded； the nursing satisfaction was evaluated.Results：After treatment，the scores of cough during daytime and at night and the total scores in the two groups were decreased when compared with those before treatment(P ＜ 0.01)，and the above scores in the observation group were lower than those in the control group(P ＜ 0.01).After treatment，the scores of cough in VAS and CQLQ in the two groups were decreased when compared with those before treatment(P ＜ 0.01)，and the above scores in the observation group were lower than those in the control group(P＜0.01).The onset time of relieving cough，the remission time and disappearance time of cough in the observation group were shorter than those in the control group(P＜0.01).The nursing satisfaction in the observation group was better than that in the control group，the difference being significant(P＜0.05).Conclusion：The ultrasonic atomizing inhalation of Jiedu Huatan tang can alleviate the cough symptoms of patients with primary lung cancer，shorten the course of disease，and improve their quality of life as well as nursing satisfaction.
