Grade of View
The Dedo-PillingĀ® laryngoscope was used exclusively in 90.7%
procedures. The median anesthetic view was grade 2a (IQR 1-2b), whilst
median surgical view was grade 1 (IQR 1-2, p<0.0001). There
was no significant correlation between the seniority of surgeon and the
view eventually obtained, although this may have been confounded by more
senior surgeons needing to take over in difficult cases. BMI and
patient-demonstrated limitations to chin and neck movement were all
significantly positively correlated with each other, and each also had
mild significantly positive correlations with higher grade (i.e. more
difficult) views (Figure 2). Neck extension was also negatively
correlated with interincisor gap (r=-0.268, p=0.001).
