Purpose: We designed our study to find optimal timing for tracheostomy, and to determine the effects of early tracheostomy on clinical courses in flame burned patients with inhalation injury.
Methods: A retrospective chart review was completed for adult patients admitted to Hangang Sacred Heart Hospital Burn Center, Hallym University Medical Center, Seoul, Korea, between March 1, 2004 and February 28, 2009, who were diagnosed with flame burn with inhalation injury and who underwent tracheostomy during their hospitalization. One hundred eighteen patients were enrolled in this study. Patients were assigned to one of three groups based on the timing of tracheostomy: postburn days (PBD) 0 to 7 [Early tracheostomy (ET) group], 8 to 12 [Intermediate tracheostomy (IT) group], and greater than 13 [Late tracheostomy (LT) group]. We compared incidence of pneumonia, duration on mechanical ventilation, length of stay in intensive care unit (ICU LOS), and survival between groups. To assess the effect of tracheostomy on pulmonary function, we analyzed changes of PaO2/Fio2 (P/F) ratio.
Results: There were 46 patients in the ET group, 47 in the IT group and 25 in the LT group. Tracheostomy day (PBD) was 5.2±1.7 in ET group, 10.0±1.5 in IT group, and 14.8±1.9 in LT group (P＜0.01). Statistics did not show the correlation between the timing of the tracheostomy and the incidence of pneumonia. Also mortality rate in each group showed no significant differences. There were significant differences between groups for duration on mechanical ventilation and ICU LOS (P＜0.01). P/F ratio correlated with time flow showed no significant differences (P=0.10). Also there were no differences between groups in changes of P/F ratio (P=0.08).
Conclusion: In flame burned patients with inhalation injury who require prolonged mechanical ventilation, performing tracheostomy within PBD 7 may shorten the duration on mechanical ventilation and length of stay in intensive care unit. (J Korean Burn Soc 2012;15:15-19)
