Three-Part Question:
[In an emergency department RSI] are [emergency medicine clinicians as effective as anaesthetists] with regard to [complications and success rates]
Clinical Scenario:
You are in the resuscitation room and are faced with a combative head injury requiring a CT scan. He needs to be intubated via a rapid sequence induction and you wonder whether you should do this, as you have previous anaeasthetic training or call the anaesthetists down to do it for you.

Author Commentary:
Although many papers look only at the performance of emergency physicians, there appears to be ample evidence that emergency physicians can perform rapid sequence induction and endotracheal intubation at least as well as anaesthetists, and there is overall a high success rate with a low complication rate. Emergency Physicians themselves must have had training in the field. Among the papers examined in this BET, several mention a trend to call anaesthetists when a difficult airway is anticipated. In our experience the use of anaesthetists is variable between departments and is often influenced by the skills available within the emergency department. It would appear that the absolute need for anaesthetists in the resuscitation room is diminishing. It is our belief that endotracheal intubation and rapid sequence induction in the emergency department should be part of an emergency physicians core skills.
Bottom Line:
There is little or no difference in the success and complication rates seen between emergency department clinicians and anaesthetists performing RSI.
