Comparison of the clinical efficacy between percutaneous dilatational tracheotomy and conventional tracheotomy

Objective To evaluate comparatively the clinical efficacy of percutaneous dilatational tracheotomy(PDT) and conventional tracheotomy for critically ill patients in ICU.Methods A total of 80 patients in whom tracheotomy was needed were given randomly either PDT or conventional tracheotomy.The mean time used for the operations,complications,and safety were compared between the two methods.Results The mean time to perform PDT was(8±3.1) min and the mean time to conventional tracheotomy was(23.7±11.3) min(P 0.01).The operation-related complications in conventional tracheotomy group were in 13 cases,but 2 in the PDT group.Conclusion PDT is safe,easy to operate,with less time,trauma,and complications,and therefore we espouse its wide application in critical patients who need tracheotomy.
