Sedation Practices of Mechanically Ventilated Patients During Critical Care Transport.

OBJECTIVE

Mechanically ventilated patients who receive deep levels of sedation have high mortality rates, longer lengths of stay, and longer duration of mechanical ventilation in the intensive care unit. Prior literature demonstrated a high frequency of deep sedation across all levels of care. Benzodiazepines have been attributed to similar morbidity and mortality findings.

METHODS

This study was a descriptive retrospective review of mechanically ventilated adult critical care transport patients from January 1, 2019, to March 11, 2020. Our primary outcome was the percentage of patients who were deeply sedated at handoff to the receiving facility. Deep sedation was defined as a Richmond Agitation Sedation Scale of -3 to -5. Our secondary outcomes were the percentage of patients who received benzodiazepines; the number of unplanned extubations, crew injuries, and unsafe patient care situations; and the incidence of ventilator dyssynchrony.

RESULTS

Five hundred fifty-three mechanically ventilated patients were transported. Ninety-three patients were excluded because they received paralytics during transport. Four hundred sixty patients were included in the analysis, 422 (91.7%) of whom were deeply sedated. Benzodiazepines were administered to 141 patients (30.6%). There were no differences observed in the secondary outcomes.

CONCLUSION

Deep sedation and benzodiazepine administration were frequent during critical care transport of mechanically ventilated patients.
