We evaluated the significance of patient's position in the measurement of gastric contents at the induction of anesthesia (n = 18). After the induction of general anesthesia with tracheal intubation, a nasogastric tube (16F) was inserted into the stomach. ⋯ The existence of the gastric content which can not be aspirated with supine position was confirmed. We conclude that it is necessary to place the patient on bilateral decubitus positions besides supine to evaluate the volume of the gastric content correctly.
