Percutaneous Dilational Tracheostomy

Abstract

In a prospective study, we performed percutaneous dilational tracheostomy (PDT) using either the Ciaglia method (gradual dilation) or the Portex [corrected] method (single dilation) in 80 patients. We encountered difficulty in dilating the tracheal stoma of three (7.5%) patients in the Ciaglia group because of tight pretracheal fascia. It was difficult to insert the tracheostomy tube in four (10%) patients in the Portex [corrected] group even after appropriate tracheal dilation. However, the tracheal cannulation was successfully completed in all patients in subsequent attempts. The mean time for completion of the procedures, from skin incision to insertion of the tracheostomy tube, was 14+/-5.5 min with the Ciaglia method and 6.5+/-3.5 min with the Portex [corrected] method. PDT with either method has not been associated with clinically significant hemorrhage, infection at the stoma site, or cosmetic deformity. In a follow-up period of 9 mo, none of our decannulated patients presented with clinical tracheal stenosis. Our results indicate that PDT with both methods is as safe and easy to organize and perform as a bedside procedure, obviating the need to transport critically ill patients from the critical care unit. The tracheas of 80 patients were cannulated through an artificial opening using either the Ciaglia (gradual dilation) or the Portex [corrected] (single dilation) method. Both techniques were successful with no significant complications. After 9 mo of closure of this opening, none of the survivors had significant scarring or narrowing of the trachea.
