Aspiration is one of the important complications of general anesthesia, although infrequent as well as accompanying high morbidity and mortality. The volume of gastric content is considered as a risk factor in this regard. Therefore, it is normally mostly recommend to consider proper fasting time before induction of general anesthesia. ⋯ In the current study in which ultrasonographic indexes, including GAG and CSA, were assessed as a suboptimal gastric emptying test method, it was found that metoclopramide could accelerate gastric emptying compared to placebo in patients with incomplete fasting before induction of general anesthesia.
