Abstract
<p class="first" id="d4214035e77">The primary aim of this study was to identify, describe
and compare the content of
existing difficult airway management algorithms. Secondly, we aimed to describe the
literature reporting the implementation of these algorithms. A directed search across
three databases (MEDLINE, Embase and Scopus) was performed. All articles were screened
for relevance to the research aims and according to pre-determined exclusion criteria.
We identified 38 published airway management algorithms. Our results show that most
facemask employ a four-step process as represented by a flow chart, with progression
from tracheal intubation, facemask ventilation and supraglottic airway device use,
to a rescue emergency surgical airway. The identified algorithms are overwhelmingly
similar, yet many use differing terminology. The frequency of algorithm publication
has increased recently, yet adherence and implementation outcome data remain limited.
Our results highlight the lack of a single algorithm that is universally endorsed,
recognised and applicable to all difficult airway management situations.
