Summary

Backround:The incidence of difficulty in laryngoscopy and endotracheal intubation is more common in obese patients. There are conflicting data on factors predicting difficult intubation. Also, these predictors are uncertain when video laryngoscopy (VL) is used. In this study we aim to investigate the correlation between airway assessment tests, anthropometric measurements and Modified Cormack-Lehane Classification (MCLC), assessed by C-MAC-D-blade VL and predictive values for intubation difficulty in class-III patients.

Methods: This prospective observational study was performed in 121 obese patients (Body mass index (BMI)≥45kg/m2) undergoing bariatric surgery. BMI, modified mallampati scores (MMS), thyromental distance (TMD), sternomental distance (SMD), interincisor distance (IID), and neck, waist, and chest circumference were all recorded preoperatively. Endotracheal intubations were performed with a C-MAC D-blade VL. The glottic view and intubation difficulty were determined according to the MCLC. MCLC I-IIa was recorded as the group with no risk of a difficult intubation, the MCLC IIb-III was recorded as the group with risk of a difficult intubation and the MCLC-IV was recorded as the group with a difficult intubation. The correlation between the airway tests, anthropometric parameters and the MCLC, as well as their sensitivity and specificity in predicting the intubation difficulty based on the MCLC, were analyzed. The duration of intubation, number of attempts, external laryngeal maneuver, the equipment requirements (style, guide), and complications during intubation were recorded.
