Perkutane Dilatationstracheotomie

Tracheostomy is a generally accepted procedure that assures free access to the airways in long-term lung ventilation. Apart from surgical tracheostomy, percutaneous dilational tracheostomy (PDT) has been increasingly employed in intensive care units. Presently, five dilatation methods are available, all equally allowing the performance of a secure and low-risk, bedside tracheostomy in the intensive care unit. Exact knowledge of the anatomy of the neck region and of the entire procedure are preconditions for a safe intervention. Percutaneous procedures offer advantages over surgical tracheostomy in terms of complications. To minimize the risks, expertise in airway management during PDT and knowledge of the particularities of cannula replacement in dilational tracheostoma, are compulsory. Endoscopic control assures that the tracheostoma can be placed correctly and that possible complications can be recognised early. The incidence of a serious tracheal stenosis after PDT is low.
