Highlights
The major responsibility of the anaesthesiologist is to provide adequate ventilation to the patient
Modified Mallampati score, Neck circumference at the level of the thyroid cartilage, Thyromental distance, Body Mass Index (BMI), distance from skin to hyoid bone and distance from skin to the anterior commissure of vocal cords using the USG machine followed by modified Cormack Lehane score (MCLS) grade on laryngoscopy were noted
Results of a study conducted by Wu J, et al in 20148, which showed that the optimal cut off values for modified mallampati score, distance from skin to hyoid bone and anterior commissure to predict difficult laryngoscopy were over Mallampati classification (MMC) grade 2, 1.28 cm and 1.1 cm respectively which were comparable to our results; in which the cut off values for modified mallampati score, hyoid bone depth (>0.81cm), and anterior commissure dept (0.92cm) were individually associated with difficult laryngoscopy
Summary
The major responsibility of the anaesthesiologist is to provide adequate ventilation to the patient. Most vital element for this is the airway. Difficulties in optimal airway management can lead to serious adverse effects and failure can even lead to mortality. Difficult airway, Modified Mallampati grade, BMI, Neck circumference, Thyromental distance, USG, distance from skin to hyoid bone (DSHB), distance from skin to the anterior commissure of vocal cords (DSAC), laryngoscopy. Evaluated the feasibility of sonography as an imaging tool in identifying important airway anatomical structures on the anterior aspect of the neck and correlated the ultrasound-guided measurements of the airway parameters with the Cormack Lehane classification of the direct laryngoscopy for prediction of the difficult airway. Aim : To predict Difficult Laryngoscopy by Ultrasound guided valuation Of Anterior Neck Soft Tissue Thickness
