Tracheal intubation, Modified Mallampati classification, Cormack & Lehane grading
Background: Difficult laryngoscopic intubation increases the risk of complications such as sore throat, serious airway trauma and aspiration of gastric contents in a patient. This study was undertaken to compare the Modified Mallampatti scores with Cormack & Lehane Scoring by Video laryngoscope and to find the correlation of Modified Mallampatti Scoring with Cormack & Lehane Scoring through Video laryngoscope.
Methodology: This cross-sectional was conducted in the department of Anaesthesiology & CCM, Nehru Hospital, BRD Medical College, Gorakhpur, U.P. India. Patients aged between 18-65 years of either sex belonging to ASA grade I & II, undergoing elective procedure from all surgical specialities requiring endotracheal intubation by Anaesthetics videolaryngoscopy were enrolled.
Results: Out of 100 cases 78 (78%) patients were females and 22 (22%) were males. The cases with ASA grade I & II were in proportion 54% and 46% respectively. According to Mallampati classification the majority of cases were with Class 1 (65%), Class 2 (25%), Class 3 (8%) and Class 4 (2%) respectively. According to Cormack & Lehane grading the majority of cases belonged to grade 1 (60%), grade 2 (24%), grade 3 (12%) and grade 4 (4%) respectively. Out of 100 cases the modified Mallampati and CL grading shows same level correlation in 71 cases while in 29 cases it was different or non-correlated. Eighty eight cases had time taken less than 15 seconds while 12 cases took more than 15 seconds for Laryngoscopy and intubation.
Conclusion: Modified Mallampati scoring and Cormack & Lehane grading is a good predictor for tracheal intubation. Despite of videolaryngoscopy use the modified Mallampati classification did not correlate grade to grade with Cormack and Lehane grading in all cases. Regular use of videolaryngoscopy may improve the overall ease of intubation.
