Educational Pearls:
- Awareness with recall of paralysis can occur in intubated and ventilated patients receiving paralytic medications
- Patients who suffer from this effect are at high risk of developing severe PTSD, depression, and suicidal ideations
- Occurs in approximately 0.1-0.2% of patients undergoing general anesthesia in an OR setting
- 2021 study showed patients intubated in the ED have a much higher rate of experiencing awareness during intubation
- 2.6% chance of awareness in patients undergoing intubation and mechanical ventilation in the ED
- Higher rates with rocuronium likely due to its longer duration of action
- New follow up study from 2022 showed 3.4% of patients aware when paralyzed for mechanical ventilation in ED
- 5.5% of patients receiving rocuronium had awareness occur
- Patients who received other paralytics had a <1% rate of awareness during intubation
- Important to be proactive with sedation and pain medications to decrease risk of awareness with recall of paralysis, especially in patients receiving rocuronium
