A study on incidence of difficult laryngoscopy and intubation using modified Mallampatti test during pre-operative assessment of patients

Abstract

Various clinical techniques have been used to assess difficult laryngoscopy, some of which are not sensitive or specific to predict difficult intubation. Hence unidentified difficult intubation can be challenging to the anesthesiologist. All patients were premedicated with Tab. Pantoprazole 40 mg given orally night before surgery. On the morning of surgery patient were shifted to the O.T, Non- Invasive Blood pressure, ECG, Spo2 monitors were connected and basal vitals were recorded. Patients were given Inj Fentanyl 2µg/kg, Inj Midazolam 25 µg/kg given IV and pre oxygenated for 3 mins. Mallampatti grade 3&4 were considered as predictors of difficult intubation. There were 29 cases out of 300 patients (9.7%) belong to Mallampatti Grade 3 & 4.
