Validation of Modified Mallampati Test with Addition of Thyromental Distance and Sternomental Distance to Predict Difficult Endotracheal Intubation in Adults Presenting in Surgical Emergency

Objective: To validate modified mallampati test with addition of thyromental distance and sternomental in prediction difficult endotracheal intubation adults presenting surgical emergency. Study Deign: Prospective, single-blinded observational study Place duration: Department Anesthesia intensive care Nishtar Hospital, Multan from August 2021 to January 2022 one year duration. Methodology: A total 120 patients were included the study. Difficult was predicted by measuring following distance. Validation combining predictors assessed sensitivity, specificity, positive & negative predictive value. Contingency table 2x2was designed. Results: The sensitivity specificity this procedure 62.5% 80.0%, respectively. Validity all parameters predict shown IV. 25.0% 27.0%, Practical Implication: Endotracheal is a common pre-operative complication having potential lead poor post operative results. This will help anesthesiologists overcome problem reduce incidence complications routine practice. Conclusion: Specificity too high, validity combine mallampati, very high when compared alone. All three MMT, SMD TMD can be used collectively for assessment airway adult planned surgery under general anesthesia. Keywords: Validity, anaesthesia, Mallampati test, intubation, distance,
