Q

What neonatal surgical emergency requires an awake intubation and avoiding use of a mask?

A

- Patient only has one good lung and you fear a pneumothorax on the good side

** Dr Pae said this was not a surgical emergency cause you are no longer correcting lung problem. I know this is a key term but this is what he said this year not sure who taught it last year
