Extubating trauma patients in the emergency department

Trauma patients often require endotracheal intubation for urgent or emergent airway protection or to allow expeditious imaging when they cannot cooperate with the needed evaluation. These patients may occasionally be extubated in the emergency department (ED) when the trauma workup is negative for consequential injuries and eventually discharged from the ED. The timing and safety of discharging these patients is unclear.

The objective of this study was to identify the adverse outcomes and evaluate the safety of extubating trauma patients who are clinically well following evaluation in the ED.

Records of trauma patients who were intubated and then extubated in the ED at a single level 1 trauma referral center during the 4-year study period (Jan 2014 - Dec 2017) were retrospectively abstracted. The primary outcome was the incidence of a post-extubation complication, including desaturation, emesis, aspiration, need for sedative administration, or unplanned reintubation. Additional outcome measures included final disposition, duration of observation following extubation, ED length of stay and return to the hospital within 72 h.

There were 59 eligible patients identified over the study period, of whom 95% presented following blunt trauma. One patient (1.7%; 95% confidence interval 0-9) required unplanned reintubation and developed aspiration pneumonia following re-extubation. Forty-two (71%) of the patients were discharged from the ED following extubation and a period of post-extubation observation with a mean of 5.8 h (0.6-16.7 h). None of the patients who were discharged returned to the ED within 72 h with complications related to extubation (0%; 95% confidence interval 0-6%).

Patients presenting to the ED with possible acute traumatic injuries who are intubated and then extubated after trauma evaluation and resolution of the indication for intubation appear to have a low incidence of complication or return visit when discharged from the ED after a brief period of observation. Specific extubation and discharge criteria should be developed to ensure the safety of this practice. Further validation is required in the form of larger and prospective studies.
