The objective of this prospective observational study was to assess the usefulness of Mallampati classification, thyromental distance (Tm) and distance from tragus to nares (Tn) in two groups of pediatric patients, those who are less than five and above five years of age, and to correlate these assessments with different grades of Cormack and Lehane (C&L) classification. One hundred and ninety six pediatric patients from one month to eight years of age, ASA grade I and II and planned for elective surgery under general anesthesia with tracheal intubation were recruited. Age, gender, weight (kg), BMI, distance between tragus and nares (cm), Mallampati grades and thyromental distance (cm) were noted preoperatively. Relationship of these variables with C&L grading at the time of laryngoscopy was recorded. C&L grades 2 & 3 was observed in 28 patients in younger age group (n = 120) as compared to two children above 5 years (n = 76) (p < 0.001). C&L grade 3 was seen with decreasing tragus to nares distance (p p = 0.025) in younger age group. In conclusion, this study showed that distance between tragus to nares, Mallampati classification (if applicable) and thyromental distance can be useful for assessment of difficult airway in children less than five years of age.展开更多

Material and Methods: In our study we had included 68 patients from September 2011 to September 2013 who needed tracheal intubation for elective maxillofacial surgery. An airway assessment test was conducted on each patient prior to general anaesthesia, with respect to mouth opening, sternomental distance, thyromental distance, oropharyngeal (Mallampati) classification and ability to protrude the mandible. After induction of anaesthesia, the laryngeal view during laryngoscopy was graded and then the ability to intubate was assessed. Results: Incidence of difficult intubation occurred in 8 (11.76%) cases out of 68 patients. Airway test that was significant for predicting difficult tracheal intubation was SMD of less than 12.5 cm, TMD of less than 6 cm, a score according to Mallampati et al. of greater than III, protrusion of mandible position B and position C and IIG less than 3 cm with sensitivity of 87.5%, 62.5%, 62.5%, 25% and 50%, respectively. Conclusion: Our study concluded that sternomental distance had the highest sensitivity of 87.5% which was statistically significant展开更多
