Abstract
BACKGROUND: Emergency endotracheal intubations outside the operating room (OR) are associated with high complications. We compare the outcome of emergency endotracheal intubation in the general ward, the intensive care unit (ICU) and the emergency department (ED). METHODS: We retrospectively analyzed adult patients requiring emergency endotracheal intubation that called for anesthesiologists at our tertiary care institution from January 1, 2015 to December 31, 2016. We evaluated the outcomes, including aspiration, hemodynamic collapse, pneumothorax, emergency tracheostomy, and survival to hospital discharge in the general ward, ICU, and ED. RESULTS: There were 416 non-OR emergency endotracheal intubation calls for the anesthesiologist. Among these areas, the ED had the highest proportion of difficult endotracheal (DET) intubation (n = 144 [80.4%]), followed by the general ward (n = 85 [66.4%]), and then the ICU (n = 65 [59.6%]). The incidence of hemodynamic collapse was higher in the general ward (n = 44 [34.4%]) than the ICU (n = 18 [16.5%]) or the ED (n = 16 [9.0%]). We reported the survival rate of the general ward (55.5%), which was lower than the ICU (63.3%) and the ED (80.4%). Among these locations, the ED had the highest rate of neurologically intact (91%) to hospital discharge, compared to the ICU (56.6%) and the general ward (55%). As for the ED, although there was no difference in survival between non-preventive and preventive intubations, preventive intubations was associated with high neurological intact with hospital discharge. CONCLUSION: Emergency and DET intubation in the general ward and ICU resulted in a higher incidence of hemodynamic collapse and mortality than those performed in the ED. Early calls for the anesthesiologist for DET intubation without medications in the ED resulted in a higher rate of neurologically intact survival to hospital discharge.
