The Difficult Airway

The Difficult Airway - 4

Can we predict difficult DL? So, what do we do?

A. Most adverse outcomes occur when airway difficulty is not anticipated.
B. Latto et al (1985) (Maybe we are a bit better now.):
43 difficult DL's in 1200 prospective patients:
50% of difficult DL's were NOT anticipated.
Only 25% of DL's that were expected to be difficult
actually were difficult.
So, 50% of difficult DL's can be predicted
with 3 times that many false positives.
C. NO, we cannot rule out difficult DL, yet, so ALWAYS BE PREPARED.
Choose an alternative technic and enjoy using it regularly! You will maintain proficiency by using your alternate technic as the first line techic whenever difficult DL seems a good possibility (about 5% of your patients). Then, when unanticipated difficulty arises, your alternate technic will be a natural and successful second choice.
