Evaluation of Accuracy of Ultrasound guided airway assessment and clinical parameters in prediction of difficult airway - A prospective analytical Observational study

This study is a prospective analytical observational study for evaluating the accuracy of ultrasound guided airway assessment and clinical parameters in prediction of difficult airway. Routine clinical parameters like h/o snoring, MMPC, ULBT, TMD(CMS), NC (CMS), HMD(CMS),SMD(CMS) will be measured. ultrasonographic measurements like ANS - VC, STB + TT, SED, SHD will be measured. On the day of surgery, theatre will be kept ready. Patient will be connected to standard monitors.18G IV cannula will be secured. After preoxygenation and premedication , all the patients will be induced with inj.propofol – 2mg/kg, post check ventilation, inj.vecuronium -0.1mg/kg will be administered. Patient will be given sniffing position ,direct laryngoscopy will be performed using appropriate sized Macintosh blade and intubated  with endotracheal tube by the same Anaesthesiologist.•        Difficult mask ventilation and intubation difficulty scale (IDS) will be noted by the investigator.

•        Anaesthesia will be maintained as per standard procedures. In case of unanticipated Cannot Ventilate / Cannot Intubate, difficult airway algorithm will be followed.

 With the help of the above collected data i.e, ultrasonographic airway assessment and clinical parameters ,the accuracy of the same and their validity in predicting the difficult airway will be assessed ,which may help for proper planning and management of safe securing of airway.
