Abstract:
Objective To analyze the correlative factors of tracheal stenosis after percutaneous tracheostomy,and to explore its contermeasures.Methods Two hundreds and eighty-six patients from February 2006 to June 2012 with percutaneous tracheostomy were selected.Five correlative factors including machinery ventilation time after operation,airway infection repeatedly,irrational use of ghcocorticoid,high position of tracheotomy and operation improper method were analyzed through Logistic regression analysis.Results Tracheal stenosis occurred in 43 cases,and the incidence rate was 15.03％ (43/286).Multivariable analysis results showed that machinery ventilation time after operation for too long (x2 =21.76,P ＜ 0.01),airway infection repeatedly (x2 =18.21,P ＜ 0.01),irrational use of glucocorticoid (x2 =9.65,P ＜ 0.01),high position of tracheotomy (x2 =4.51,P ＜ 0.05) and operation improper method (x2 =4.33,P ＜ 0.05) were associated with postoperative concurrent tracheal stenosis.Conclusions There are many factors coreelate to tracheal stenosis after percutaneous tracheostomy,in which the machinery ventilation time after operation and airway infection repeatedly are the main reasons,and irrational use of glucocorticoid,high position of tracheotomy and operation improper method are secondary causes.
