Publication Open Access Visibility of pharyngeal structures as a predictor of difficult intubation(Blackwell Publishing Ltd, 1987-10) Charters, P; Perera, S. V. T; Horton, W. AVisibility of pharyngeal structures as a predictor of difficult intubation Page 1 Correspondence 1115 Visibility of pharyngeal structures as a predictor of difficult intubation We would like to comment on the study by Samsoon and Young (Anuesihesh 1987; 42: 487-90) since we also have experience with the test which forms the basis of their report. Mallampati’s test scores the visibility of pharyngcal structures (faucial pillars, soft palate and uvula) in an attempt to predict difficult tracheal intubation. Three of us used this test as part of a pre-operative asscssmcnt in a study about tracheal intubation. Sainsoon and Young did not make it clear in their paper hut thcy did not make the assessment in the way described by Mallampati. We also chosc to examine our patients with ‘the head in the neutral position’ and the observer sitting ‘opposite at eye level’. We graded paticiits class 1 to 3 as originally described because Mallampati …Publication Open Access Visibility of pharyngeal structures as a predictor of difficult intubation(Blackwell Publishing Ltd, 1987-10) Charters, P; Perera, S.

K. N. DThe present study is concerned with the motion of a long cylindrical elastic bar which is partially embedded in a homogeneous elastic half-space and subjected to a harmonic axial load. Initially Green's functions corresponding to axisymmetric harmonic ring loads are derived and presented explicitly. It is found that the direct extension of elastostatic solution schemes to solve elastodynamic problems may lead to erroneous solutions due to the inability of these algorithms to properly account for inertia effects. Some discrepancies in existing solutions with respect to the inertia component of the bar are shown. An efficient solution scheme, based on Lagrange's equation of motion and a discretization technique, is presented to solve the title problem. Numerical results are presented to illustrate the influence of bar flexibility, mass density, geometry, and frequency of excitation on the axial impedance of the system.
