Summary

Pulmonary aspiration is one of the most serious risks of general anesthesia and has been reported to occur in as many as 1 in 4000 cases of general anesthesia. Gastric ultrasound is an emerging point-of-care tool that provides bedside information on gastric content and volume.

There have been a few factors which are thought to increase gastric size. Delayed gastric emptying such as caused by gastroparesis in Diabetes Mellitus is an example. Certain surgeries also cause gastroparesis. Other preoperative factors including pain, preoperative anxiety, and blood levels of estradiol or progesterone are less well studied.

Conditions

  • Ultrasonography

Interventions

DIAGNOSTIC_TEST

Gastric Ultrasound

In the operating room, a gastric ultrasound will be performed in the supine position and the antral cross sectional area will be measured. Anesthesia will be induced in standard procedure and positive pressure will be instituted according to the standard protocol accepted in our hospital. At the end of the procedure, the gastric ultrasound circumference will be measured again.
