Comparison of gastric inflation during mask ventilation at two different tidal volumes for induction of general anaesthesia.

Not yet recruiting

• Conditions: Medical and Surgical,

• Registration Number: CTRI/2023/07/055095
• Lead Sponsor: Department of Anaesthesia

Brief Summary

We propose to compare tidal volumes of 6ml/kg and 8ml/kg ,by ultrasound guided estimation of gastric inflation i.e. Increase in size of gastric antrum by comparing the cross-sectional area before and after three minutes of facemask ventilation. This will be combined with real-time monitoring of left paratracheal esophageal air entry and evaluation of changes in arterial carbon dioxide values before and after three minutes of facemask ventilation by arterial  blood gas analysis.
