Introduction
Management of the difficult airway is associated with
significant morbidity and mortality in critically ill
patients.
An increasing array of advanced airway tools are
available, but appropriate selection and application
in the ICU remains poorly defined.
Difficult airway incidence during emergent intubation
is 10%, but complications of ICU airway
management remain common
the importance of interdisciplinary critical care team
preparation, training, and teamwork, and the
application of various advanced airway adjunct to
maximize intubation success and minimize com
plications in this environment
The Difficult Airway
ASA : difficult airway as the existence of clinical
factors that complicate ventilation by facemask or
intubation by experienced and skilled clinicians [5]
Jaber et al. [4] : complications in 50% of 253 ICU
intubations, 28% including severe complications
(serious hypoxemia, hemodynamic instability,
cardiac arrest or death)
Martin et al. [6] : Although 44% of these
complications occurred in the ICU, the proportional
rate of complications was significantly less than that
associated with intubations performed on a ward
(P<0.001).4. Jaber S, Amraoui J, Lefrant JY, et al. Clinical practice and risk factors for immediate complications of endotracheal intubation

Preparation
Decide whether the basic problem is :
- Difficult ventilation
- Difficult intubation
- Uncooperative patient
Try more active to manage difficult airway
Consider the purpose of the management
- awake intubation vs intubation after induction
- Invasive or non-invasive intubation approach
- Decide the main strategy and always think about plan B

Conclusion
A systematic approach to intubation management
that emphasizes planning, preparation, and team-
work can significantly reduce intubation
complications.
Management of Difficult airway must apply the
general principles available from current medical
evidence
