To Study the Correlation Between Sonographic Modification of Cormack Lehane Scoring With Actual Cl Grading During Direct Laryngoscopy

Abstract

Background: Airway assessment is an essential aspect of preanaesthetic assessment. Presently, prediction of difficult airway is based on clinical assessment of airway.
 Methods: Prospective Observational conducted at Department of Anesthesiology, Dr. RPGMC Kangra at Tanda, Himachal Pradesh.
 Results: It was observed that 44% patients (n=88) were in grade 2 followed by 27 % (n=54) in grade 1, grade 3 was observed in 24.5% patients (n=49) whereas Cormack Lehane grade 4 was seen in 4.5% patients (n=9)
 Conclusion: The thyromental distance was more than 6.5 cm in the majority of patients (87.5%) while 12.5% had a thyromental distance less than 6.5 cm. There was a significant difference in Thyromental distance between different Cormack Lehane grades (P=0.001)
