Modified technique of percutaneous dilational tracheostomy in 600 cases.
Tracheostomy is frequently required for the treatment of critically ill patients to prevent the complications with prolonged translaryngeal intubation. It may facilitate airway suctioning and improve patient comfort during the process of weaning. The purpose of the study was to introduce a new modified technique for percutaneous dilational tracheostomy (MPDT) and assess its advantages. From November 1997 through December 2000, a series of 600 patients (350 men, 250 women; mean age 44.5 years) underwent MPDT in our department. The technique we used is a combination of the Seldinger and Schachner techniques with an incision of 2 to 3 cm between the cricoid cartilage and the notch. Using a small automatic retractor, the thyroid muscles were dissected with the help of a curved mosquito clamp. This gave us the opportunity to control the isthmus and offered the possibility of ligation when the thyroid was large, providing a good operative field directly on the trachea. Hence we avoided traumatizing the isthmus, which is the main source of hemorrhage during this procedure. The mean operating time was 4.5 minutes. The morbidity rate was 0.04%. One patient developed a subcutaneous emphysema and in three cases we had to ligate the external jugular vein. The surgical incision was completely healed within 3 to 4 days after removing the tracheostoma. No tracheal stenoses were observed during the follow-up. MPDT is a safe, applicable technique that can be performed quickly even by a nonsurgeon in the intensive care unit and emergency department, with a low risk of complications because there is a direct view of the trachea and minimal trauma.
