Brief Summary: Difficult Airway Prediction is an important part of pre anaesthesiaassessment as it facilitates planning and preparing to manage a difficultairway. This in turn will enable a smooth perioperative course and reducedperioperative morbidity. Conventional physical assessment for difficult airwaycan sometimes fail to identify a difficult airway. This has made Point of CareUltrasonography (POCUS) as an evolving tool for airway assessment.

In this study, both Male and Female Patients above 18yrs ofAge, Classified as per American Society of Anaesthesiologist as ASA1,ASA 2,posted for Elective Surgeries planned under General Anaesthesia usingendotracheal intubation are included. Pregnant women, Patients with knownairway (Oral, pharyngeal, Laryngeal) pathologies, Cervical Vertebral diseases,Large Thyroid and Parathyroid Swelling, Submandibular Salivary Gland Pathology,Healed Post Tracheostomy scar, Post Burn Contractures of Neck, or any scar overthe neck and patients posted for Oro-Pharyngeo-Laryngeal procedures andEmergency surgeries are excluded from this study.

In this study, after consent for the study, the airwayphysical assessment using SARI scoring is evaluated preoperatively.Preoperatively (before Intubation) On the day of Surgery, in the operatingroom, the primary investigator or co-investigator shall measure Distance fromSkin to Epiglottis (DSE)and Hyomental Distance (HMD) with neck neutral, extended and in rampedpositions ,and tongue thickness (TT) using ultrasound, thus completing thetests in the DARES protocol. It is planned that 15% of Sample size done by the Primary Investigator shall bevalidated by Radiologist – Co Investigator. . If the Primary investigator’sassessment is not comparable to Radiologist - Co Investigator, then patientsassessed by Primary investigator prior shall be dropped and the PrimaryInvestigator shall be undergoing further training with the co – investigator.Post Training Primary Investigator will continue the study.

The Senior Anaesthesiologist posted on the elective list whois not aware of the recorded SARI scoreand DARES protocol measurements will intubate the patient and record the IDSscore obtained.

POCUS predictive value in Difficult Airway Assessment usingthe DARES protocol, will be calculated and compared with conventional physicalairway assessment using the SARI score The difficulty of airway management will be calculated based onthe IDS score.
