Review of percutaneous tracheostomy.

The purpose of this study is to assess the safety and efficacy of the four known methods of percutaneous tracheostomy. Perioperative, postoperative, and late complication rates were generated for each method after a complete literature review identified 1684 percutaneous tracheostomy patients reported in 40 series. Two methods, the Toye and the guide wire dilator forceps (GWDF) methods, have been the subject of few investigations. Two other methods have been extensively studied. A high perioperative complication rate was calculated for the Rapitrac method, whereas percutaneous dilational tracheostomy (PDT) has complication rates similar to those reported for standard operative tracheostomy. A retrospective review of 22 patients who underwent PDT at a local community hospital confirmed a "learning curve" for this technique that had been previously suggested. Review of the literature suggests that PDT can be safe and cost-effective for selected patients, but a learning curve for this technique exists that dictates caution, experience, and preparation on the part of any surgeon who wishes to add percutaneous tracheostomy to his or her repertoire.
