The ratio of Height to thyromental distance has been reported to have a good predictability. This study tested the performance of ratio of height to thyromental distance and compared it with commonly performed airway evaluation tests: the modified Mallampati test and upper lip bite test. This descriptive study was conducted in 120 patients presenting for surgery under general anesthesia with endotracheal intubation. Preoperative airway assessment was done using Modified Mallampati test, upper lip bite test and ratio of height to thyromental distance. The Cormack and Lehane grading was done during laryngoscopy to determine easy or difficult visualization of larynx. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of three tests were calculated. Difficult laryngoscopy was seen in 9 patients (7.5%). The sensitivity, specificity, positive predictive value, negative predictive value respectively for the tests were modified Mallampati test (22.2%, 89.2%, 14.3% and 93.4%), upper lip bite test (22.2%, 100%, 100% and 94.1%), ratio of height to thyromental distance (77.8%, 95.5%, 58.3% and 94.16%). In conclusion, we found that the ratio of patient’s height to thyromental distance performed better than MMT and ULBT in predicting difficult visualization of larynx in our population.","PeriodicalId":506882,"journal":{"name":"Nepal Medical College Journal","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139163809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objective of this study was to analyze the quality of MCQs and to assess the relationships of items having good difficulty and discrimination indices with their distracter efficiency. After getting an ethical approval from Institutional Review Committee of Nepal Medical College Teaching Hospital a cross – sectional study was conducted over a period of one year from January 2022 to December 2022 in the Department of Human Anatomy of Nepal Medical College. The difficulty index (DIF I), discrimination index (DI) and distracter efficiency (DE) were calculated and analyzed. The results obtained revealed that the mean and standard deviation of DIF I, DI and DE were 56.75±22.6, 0.3±0.2 and 43.24±25.66 respectively. The items analyzed were neither too easy and nor too difficult (DIF I = 62.8%). The majority of items fulfilled the criteria of acceptable difficulty and good discrimination index and the maximum number of items were found to have 2 NFDs (DE = 33.33 %). The present study was hence undertaken as it assists to evaluate the MCQ items to discern its effectiveness in assessing the knowledge of students as well as it plays a vital role in developing a question bank having valid MCQs.","PeriodicalId":506882,"journal":{"name":"Nepal Medical College Journal","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139163819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
