Chewing Gum and Anesthesia

There has been debate about whether patients should be disallowed to chew gum before anesthesia and the risk of aspiration.

This correspondence and cross references suggest that in healthy volunteers gum chewing was not associated with increased gastric fluid volume measured 2 h after the oral intake of 250 ml of water.

Future studies incorporating gastric ultrasound in clinical patients may lead to a more liberal view, and the potential of chewing gum to even improve gastrointestinal recovery in ERAS protocols.
