[Percutaneous dilatational tracheostomy].

Abstract

BACKGROUND: Tracheostomy provides a method for long-term ventilation in intensive care, which reduces the risk of necrotizing lesions of the pharyngeal and laryngeal mucosa. Since the introduction of the percutaneous dilatational tracheostomy, experienced physicians are able to perform bedside tracheostomies. This presentation reviews the complication rate and long-term outcome of percutaneous dilatational tracheostomy. PATIENTS AND METHOD: The method was applied in 57 patients following previous orotracheal intubation averaging 7.8 days (3 to 15 days). Underlying diseases were sepsis/SIRS in 29, stroke in 7, cerebral hypoxemia after cardiopulmonary resuscitation in 10, trauma in 7, prolonged weaning in 2, primary neurological diseases in 2. RESULTS: The following complications occurred during the procedure: 1 major and 7 minor bleedings. 2 subcutaneous emphysemas, 1 mediastinal emphysema following tracheal injury. No complication required surgical intervention. In the follow-up 17 patients (30%) died from their underlying disease, none from complications of the tracheostomy. After removed of the tracheal tube, in 39 patients the stoma closed spontaneously within 7 to 14 days. In 8 patients the tracheostoma persisted for more than 3 months, but no clinically relevant tracheal stenosis was found. CONCLUSION: Percutaneous dilatational tracheostomy is a safe procedure easy to perform in intensive care units. Bronchoscopic control is necessary to avoid complications.
