Summary

Evaluation the role of ultrasound measured hyomental distance to tongue thickness ratio in predicting difficult intubation in infants

Detailed description

Sonographic assessment of the airway after induction of anesthesia and Master Degree Thesis / MFA/ISRO/ Faculty Of Medicine/ASU Page 6 intubation: All infants will be placed in a supine position with their heads slightly extended. Then, the low-frequency probe (curved) will be first placed under the chin in the midsagittal plane and adjusted to show a clear view of the entire tongue outline and the border of the mandible and hyoid bone on the screen. The image will be frozen and stored. On the image the tongue thickness will be measured, which is the maximum vertical distance from the sub mental skin to the tongue surface (Yao W, Wang B 2017). After that, the HMDE will be measured, which is the distance from the lower border of the mentum of the mandible to the upper border of the hyoid bone.
