Background and Aim:Predicting difficult laryngoscopic view and intubation is an essential problem in anesthesiology. In this study diagnostic value of stemomental distance measurement is assessed.
Materials and Methods:In this cross sectional study, in 500 patients 15 to 65 years old who were planned for general anesthesia, stemomental distance, difficult larangoscopic view, difficult intubation and Association of stemomental distance with variables were determined.
Results: Mean (±SD) stemomental distance was 16.7±2.3 cm. Stemomental distance was significantly correlated with sex (p< 0.001), age( p< 0.001) , difficult laryngoscopic view (III or IV grade) ( p<0.001) and difficult intubation ( p< 0.001). 15.5 was the selected cut point for stemomental distance. The diagnostic value of stemomental distance in predicting difficult laryngoscopic view and intubation were: sensitivity: 79.2, 77.4 specificity: 68.1, 68.7 positive predictive value: 11.1, 14negative predictive value: 98.5, 97.9, respectively.
Conclusion: measuring the stemomental distance as a predictor in difficult laryngoscopic view and intubation is helpful but not sufficient
