Design outcomes

Primary

MeasureTime frame
To Compare the effect of cricoid, paralaryngeal, and Paratracheal pressure, respectively, on the outer anteroposterior diameter of the upper oesophagus using an ultrasound probe in patients undergoing elective surgeries during induction of general anaesthesia. Timepoint: Right after 3 minutes of administration of vecuronium—

Secondary

MeasureTime frame
To identify the location of the oesophagus entrance relative to the glottis & the location of the oesophagus relative to the trachea in an anesthetized, paralyzed state and during direct laryngoscopy To compare the POGO score during direct laryngoscopy with or without cricoid, paralaryngeal, and paratracheal pressureTimepoint: 3 mins after vecuronium before laryngoscopy for identifying location of oesophagus. During direct laryngoscopy ( first attempt ) for POGO score—
