ObjectiveThe role of tracheostomy in burn patients is controversial. Previous studies, primarily in adults, suggested that severely burned patients with tracheostomies have a higher incidence of tracheostomy site infections, mortality, and pneumonia. The purpose of this study is to determine the safety and efficacy of early tracheostomy in severely burned children.DesignCase series study analyzing mechanical ventilation and sedation requirements before and 24 hrs after tracheostomy.SettingRegional pediatric burn center.PatientsAll children admitted to a regional pediatric burn center requiring tracheostomy from March 1, 1998, to October 1, 2001.MethodsData were recorded on patients' demographics, extent of burn, presence of inhalation injury, and mortality. Mechanical ventilation variables measured pretracheostomy (pre) and posttracheostomy (post) and included mode of ventilation, ventilator settings, peak inspiratory pressures, and arterial blood gases (Pao2, Paco2, pH, and oxygen saturation). Calculated variables included compliance, Pao2:Fio2 ratio, and minute ventilation. Tracheostomy-related variables recorded included the interval to tracheostomy insertion, the duration of tracheostomy, and tracheostomy complications.Main ResultsA total of 38 patients (with a mean age of 4.7 +/- 0.6 yrs and a mean total body surface area involvement of 54% +/- 4%, 63% with inhalation injury) underwent tracheostomy a mean of 3.9 +/- 0.7 days after admission. Overall mortality was 21%. There were no tracheostomy site infections, tracheostomy-related deaths, or tracheal stenoses in survivors. Peak inspiratory pressures were lower after tracheostomy (30.4 +/- 1.4 [pre] vs. 27.6 +/- 1.5 cm H2O [post]; p <.05), ventilatory volumes were higher (190 +/- 22 mL [pre] vs. 225.5 +/- 25 [post]; p <.05), compliance improved (10.5 +/- 1.4 [pre] vs. 15.1 +/- 2.3 mL/cm H2O [post]; p <.05), and the Pao2:Fio2 ratio improved (300.6 +/- 20 [pre] vs. 348.6 +/- 16 [post]). There was no difference in oxygenation, ventilation, minute ventilation, or pH after tracheostomy.ConclusionsEarly tracheostomy in severely burned children is safe and effective. It provides a secure airway and may result in improvement in ventilator management for these children.
