Abstract

Background: Difficulty in tracheal intubation has always been a problem in both elective and emergency setting. The aim of this study was to compare the newly designed test, the Upper Lip Bite Test, (ULBT) with prevailing Tests – the Hyomental /Thyrostemal distances ( HMD, TSD ) and the Mandible length (ML) in predicting difficulty in intubation.Methods and Materials: A total of 300 patients meeting the inclusion criteria were enrolled in this study. Each patient was assessed by a resident of Anesthesiology, regarding the ULBT, HMD, TSD and ML, and Laryngoscopy was Performed by the Anesthetics blinded to the measurements obtained and grading recorded using the Cormack and Lehane laryngoscopic grading system. The data obtained were analyzed using chi square and ANOVA. Results: The results showed 11.3% incidence of difficult intubation. Sensitivity and Specificity of ULBT were 94% and 100% respectively, being the highest compared to TSD which were the lowest being 88% and zero percent. respectively .ULBT class III had a direct correlation with HMD<3.5cm (p=0.00), and ML < 9cm (p<0.01). ULBT had the highest positive and negative predictive values (100% and 47%) respectively. Accuracy of ULBT was found to be 94%, again the highest among the four tests.Coclusion: In conclusion, ULBT was found to have the highest Sensitivity and Specificity and accuracy, and could be used as a single bed test in predicting difficulty in intubation.
