  1. Effect of a new intubation device on the sterno-mental distance in obese patients Jan Paul J Mulier, M.D., Ph.D., Department of Anaesthesiology AZ st-Jan AV, Brugge, Belgium. Jan.Mulier@azbrugge.be • Materials and Methods • 20 patients, ASA I, II and III, 21 - 75 y, bmi > 25 • Approval from the hospital ethical committee. • Intubation device is positioned uninflated under the thoracic spinal column. The head is positioned in the sniffing position with maximum extension. The sterno mental distance is measured in cm as described by Savva D. The intubation device is inflated to its volume of 2,5 liter and the sterno mental distance is measured again. • Following parameters are noted for each patient: age, body weight, length, sex, BMI. • A paired t test on sterno-mental distance with and without intubation device. • Linear regression analysis is used to describe the parameters that correlate significantly with the sterno-mandibular length and length increase. • Background and Goal of Study • The sterno mental distance determines the difficulty in intubation. • Elevation of the upper body by an angulated pillow facilitates the intubation in obese patients. • Pillow positioning and removal are difficult in obese patients. • Elevation of the shoulders is not needed • The new proposed device is a trapezoidal inflatable bag put under the thoracic column and not under the shoulders. • It lifts and rotates by its trapezoid size only the thoracic column. • It can be positioned flat under the patient. • Only at the moment of intubation it is inflated and no removal is needed during the operation. Goal of this study was to measure the sterno mental distance, before and after inflation of the new intubation device Results and Discussions Inflating the intubation device increases significantly the sterno mandibular length from 12,1 cm to 16,3 cm. significant (p = 0,003). The BMI correlates significantly with the initial sterno mental distance. A short sterno mandibular distance correlates significantly with the length increase when the intubation device is inflated. . Comparing deflated (off) with inflated (on) intubation device on SM distance Conclusion The inflatable intubation device significantly increases the sterno mandibular distance. References • 1.
