Abstract

Background: Recently, various methods are used to determine the difficult laryngoscopy. In this study, we tried to compare the acromioaxillosuprasternal notch index (AASI) function with old head and neck anatomic criteria in predicting difficult laryngoscopy in trachea intubation under general anesthesia in children.

Methods: in this cross-sectional study, 379 children under intubation with general anesthesia entered the study. Patients were divided into two groups of easy laryngoscopy (grade 1 and 2) and difficult laryngoscopy (grade 3 and 4) based on Cormack-Lehane score. Thyromental distance systems, height to thyromental distance, ULBT test, neck circumference and AASI were studied and compared.

Results: laryngoscopy was difficult in 48 subjects (38 grade 3 and 10 grade 4). There was no significant difference between easy and difficult laryngoscopies based on the thyromental distance, neck circumference, height to thyromnetal distance and AASI (P>0.05). Height to thyromental distance, AASI, and neck circumference have sensitivity of 32.2%, 47.9%, 51.1%, respectively and the specificities were 52.7%, 45.6%, and 48.9%, respectively.

Conclusion: neck circumference and ASSI outperform the height to thyromental method. On the other hand, MMT is better than ULBT in determining difficult laryngoscopy in children.
