Adnet et al developed the Intubation Difficulty Scale (IDS) to describe the difficulty involved in intubating a patient. The authors are from the University of Paris VII and XIII.
Parameters:
(1) number of attempts
(2) number of operators
(3) number of alternative techniques
(4) Cormack grade (see 31.05.02, above)
(5) lifting force required
(6) laryngeal pressure
(7) vocal cord mobility

total score =
= SUM(points for all 7 parameters)
Interpretation:
• minimum score: 0
• maximum score: > 20 (an impossible intubation is graded as infinite).
