Efficacy of tiotropium inhalation powder for recovery of lung function after lung cancer / 中国基层医药

ABSTRACT

Objective To investigate the clinical efficacy of thiophene tiotropium powder inhaler for postop-erative lung function recovery in lung cancer patients.Methods 80 patients of thoracic surgery lobectomy who had lung cancer were selected as research subjects.The patients were randomly divided into two groups.The observation group received tiotropium bromide powder for inhalation therapy,the control group was inhaled salmeterol /fluticasone propionate powder for inhalation therapy.Before treatment,after treatment,2d,6d of CRP,absolute neutrophil ANC, tumor necrosis factor α(TNF -α) were observed.Before treatment,after treatment 4 weeks,8 weeks of forced vital capacity (FVC),within one second force expiratory volume in FEV1 ,FEV1 percent predicted (FEV1%),FEV1 /FVC, PaO2 ,PaCO3 were detected.Results Before treatment,CRP,AND,TNF -αhad no significant differences between the two groups (all P >0.05).Postoperative 2d,CRP,ANC,TNF -αof the two groups were all increased.Postopera-tive 6d,the above indicators of the two groups were declined,and the decline of the observation group was significantly lower than the control group (t =3.163 4,3.651 8,4.025 3,all P 0.05).4 weeks,8 weeks af-ter treatment,FVC,FEV1%,FEV1 /FVC,PaO2 of the observation group were significantly higher than the control group (t =2.041 8,4.116 7;2.043 1,3.722 8;3.056 2,4.138 6;3.227 6,5.161 9;all P <0.05),FEV1 ,PaCO3 were significantly lower than the control group (t =1.523 7,3.427 6;3.439 2,4.521 7;all P <0.05).Conclusion Tiotropium bromide inhalation powder agents has certain effect on lung function recovery for lung cancer patients after surgery,it is worthy of clinical application.
