BackgroundAlthough there have been many studies dealing with tracheostomy timing in trauma patients, the optimal timing is still being debated. This study aimed to compare outcomes between early tracheostomy (ET) and late tracheostomy (LT) in trauma populations to estimate the optimal timing of tracheostomy after intubation.MethodsWe retrospectively reviewed the 5 years' data of trauma patients who underwent tracheostomy during their acute intensive care unit (ICU) stay. The cases were divided into two groups: ET was defined as tracheostomy performed within 7 days after intubation, and LT, after the seventh day. Propensity score matching was utilized using a 1-to-1 matching technique, and outcomes between two groups were compared.ResultsAmong 236 enrolled patients, 76 met the criteria for ET and 160 were included for LT. Using propensity matching, 70 patients who met the criteria for ET were matched to 70 patients in the LT. Based on the comparison of outcomes after matching, ET showed significantly shorter values than LT in overall ventilator duration, length of stay at the ICU, and post-tracheostomy ventilation duration. Furthermore, the incidence of pneumonia was significantly lower with ET than with LT, although the rate of postoperative complications showed no significant differences.ConclusionsWe suggest that ET should be considered in trauma patients needing prolonged mechanical ventilation. Also, we recommend that surgeons perform tracheostomy as early as within 7 days after intubation to not only reduce the ventilation and ICU days but also prevent pneumonia without worrying about an increase in postoperative complications.
