Rationale for 'early' percutaneous dilatational tracheostomy in patients with burn injuries

Abstract

Several investigators have cited the numerous complications that occur with conventional tracheostomies in patients with burn injuries. However, none of these studies included the technique of percutaneous dilatational tracheostomy, which has been shown to significantly decrease operative time, cost, perioperative, and long-term sequelae as compared to conventional tracheostomy. A retrospective analysis of 36 patients with burn injuries, from 1400 burn admissions, was conducted to compare conventional tracheostomy versus percutaneous dilatational tracheostomy. In this study, percutaneous dilatational tracheostomy resulted in significantly decreased operative times and cost compared to conventional tracheostomy. There were no major operative complications in either group, and alveolar-arterial oxygen gradients were improved in 71% of the patients with a tracheostomy. Percutaneous dilatational tracheostomy is an efficacious technique for airway management in patients with burn injuries. It can be safely performed at the bedside, at one fourth the cost of a conventional tracheostomy. Percutaneous dilatational tracheostomy may also benefit the patient with severe burns by decreasing alveolar-arterial oxygen gradients. Improved ventilatory mechanics might allow for a shorter duration of mechanical ventilation, thereby decreasing patient morbidity, hospital stay, and cost.
