Time to stop sniffing the air: snapshot survey
Chris Johnson1, Neville W Goodman
1Southmead Hospital, Bristol BS10 5NB.
Objective:
To determine whether the phrase "sniffing the morning air" is useful in positioning patients for tracheal intubation.
Design:
Snapshot survey.
Setting:
Teaching hospital.
Participants:
21 anaesthetists.
Main Outcome Measures:
Angles of neck, line of sight, and hip to shoulder, as measured on a photograph.
Results:
Angles ranged widely, especially line of sight: 7 degrees -37 degrees with horizontal.
Conclusions:
As patients are positioned supine, rather than standing, the phrase is unhelpful; an explicit description of head position would be better.
