Chapter 2. The Algorithms
All of the following are features of well-designed, clinically useful algorithms EXCEPT
A. They are designed by reputable organizations.
B. They have clear entry and exit points.
C. Decision points are binary.
D. They are easily remembered in crisis.
E. They are easy to represent graphically.
(A) With the exception of reputable organizations, all are important features of well-designed, clinically useful algorithms.
All of the following are true of the ASA Difficult Airway Algorithm EXCEPT
B. It has likely helped to reduce the rate of airway management failure in anesthesia practice.
C. It is meant to represent the “standard of care” in medicolegal proceedings.
D. It has two sections: one for the difficult airway and one for the failed airway.
E. The use of the LMA is a discrete step.
(C) The ASA Practice guidelines are not intended as standards or absolute requirements as the use of practice guidelines cannot guarantee any specific outcome.
All of the following are identified weaknesses of the ASA Difficult Airway Algorithm EXCEPT
A. The algorithm actually addresses both difficult and failed airway management, but does not explicitly identify the two pathways.
B. The non-binary nature of the decision matrices and the multiplicity of pathways have limited the clinical usefulness of the algorithm in guiding day-to-day practice.
C. The algorithm does not provide for uncooperative patients (children, mentally challenged, and patients who refuse to cooperate with the planned airway management) and different patient populations (e.g., obstetrical and pediatric patients).
D. The algorithm is silent with respect to whether or not they ought to apply outside the operating room.
E. The algorithm is clear that awakening the patient is not always possible.
(E) In additional to all the listed weaknesses of the ASA Difficult Airway Algorithm, the algorithm is also unclear that awakening the patient is not always possible.
