You decide to intubate the girl.

An anaesthetist once told you to use profol for a rapid sequence induction, so you do.

The fitting stops. You successfully intubate with a size 4.0 ETT, and begin to ventilate her with a bag.

You are feeling a little smug when she begins to fit again. her saturations drop to the 50%.

Perhaps there wasn't so much wrong with her airway after all.
