Brief summary

Using bedside ultrasound, the investigators will examine gastric content in non-fasting patients assigned to rapid sequence intubation (RSI). The procedure will be done immediately before intubation. The percentage of non-fasting patients who actually have gastric content will be determined. Identifying gastric content is critical because presence increases the risk of pulmonary aspiration during intubation.

Detailed description

Quantitative gastric content will be registered by measuring the cross section area of antrum using bedside ultrasound. The area and the patients age will be applied to estimate gastric volume.
