RESUMO
Objective To explore the clinical application of improved thoracic closed drainage tube vacuum aspiration in treatment of elderly patients with trachea foreign body.Methods 32 elderly patients with trachea foreign body were divided evenly into group A and group B.Group A received treatment of improved thoracic closed drainage tube aspiration,while group B received treatment of bronchoscopy.One-time success rate of removing foreign body,operation duration,length of stay and occurrence of complications were compared between group A and group B.Results One-time success rate of removing foreign body in group A was significantly higher than group B (100.00％ vs 81.25 ％,x2 =6.720,P ＜ 0.05) ;operation time of group A was (1.79 ± 1.25)min,which was significantly shorter than (13.18 ± 4.37) min of group B (t =4.31,P ＜ 0.05).Conclusion The clinical effect of improved thoracic closed drainage tube vacuum aapiration in treatment of elderly patients with trachea foreign body was positive and better than treatment with bronchoscopy,it is worthy of clinical application.
