Insights
Early tracheostomy is safe and effective for severely burned children, improving ventilator management without increasing infection risks. This procedure provides a secure airway for pediatric burn patients.
Area of Science:
- Pediatric critical care medicine
- Burn management
- Surgical airway procedures
Background:
- The role of tracheostomy in pediatric burn patients remains controversial.
- Previous adult studies indicated higher risks of infection, mortality, and pneumonia with tracheostomies in severe burn cases.
- Limited data exists on the safety and efficacy of early tracheostomy in severely burned children.
Purpose of the Study:
- To evaluate the safety and efficacy of performing early tracheostomy in severely burned pediatric patients.
- To assess the impact of tracheostomy on mechanical ventilation parameters in this population.
Main Methods:
- A case series study was conducted at a regional pediatric burn center.
- Data from children requiring tracheostomy between 1998 and 2001 were analyzed.
- Mechanical ventilation variables and tracheostomy-related complications were recorded and compared pre- and post-procedure.
Main Results:
- Thirty-eight severely burned children underwent tracheostomy, with 63% having inhalation injuries.
- No tracheostomy site infections, procedure-related deaths, or tracheal stenoses were observed in survivors.
- Significant improvements were noted in peak inspiratory pressures, ventilatory volumes, compliance, and the Pao2:Fio2 ratio post-tracheostomy.
Conclusions:
- Early tracheostomy is a safe and effective intervention for severely burned children.
- The procedure facilitates secure airway management.
- Tracheostomy may lead to improved ventilator management strategies for pediatric burn patients.
Objective:
The 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.
Design:
Case series study analyzing mechanical ventilation and sedation requirements before and 24 hrs after tracheostomy.
Setting:
Regional pediatric burn center.
Patients:
All children admitted to a regional pediatric burn center requiring tracheostomy from March 1, 1998, to October 1, 2001.
Methods:
Data 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 Results:
A 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.
Conclusions:
Early 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.
