Abstract:Objective: To observe the clinical application effect of ultrasound guided percutaneous dilational tracheostomy (PDT) in establishment of artificial airway for critically ill patients. Methods: 90 critically ill patients in intensive care unit (ICU) from March 2016 to April 2017 were selected, and PDT was performed in establishment of artificial airway. They were randomly divided into 2 groups, 45 cases in each group. Group A was treated by ultrasound guided PDT, while group B was treated by fiber bronchoscope assisted PDT. The operative indexes, tracheal intubation, postoperative recovery indexes and incidence of complications were compared between the 2 groups. Results: The operative time, bleeding volume and air leakage rate of air bag in group A were shorter / less / lower than those in group B (P < 0.05). There was no significant difference between the 2 groups in the length of incision, the incidence of intraoperative hypoxemia, the success rate of initial intubation, the distance of tracheal intubation backing to the incisor, postoperative weaning time, extubation time, length of stay in ICU, total length of stay hospital or total incidence rate of postoperative complications (P > 0.05). Conclusion: Compared with fiber bronchoscope, ultrasound guided PDT in establishment of artificial airway can shorten the operative time and decrease the bleeding volume and air leakage rate of tracheal intubation during operation, and it has high safety and accuracy.
