Preoperative Presence of Gastric Content in Non-fasting Patients - an Ultrasound Study

Completed

• Conditions: Non-fasting Patients; Rapid Sequence Intubation; Anesthesia Intubation Complication
• Interventions: Other: Bedside ultrasound

• Registration Number: NCT03685435
• Lead Sponsor: University Hospital, Akershus

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.

Arm && Interventions

Group	Intervention	Description
Non-fasting patients	Bedside ultrasound	We will examine non-fasting patients using bedside ultrasound. First we examine the gaster in a supine position. Then we repeat the procedure in a right lateral position.

Primary Outcome Measures

Name	Time	Method
Low risk of aspiration	Immediately before intubation	Detection of empty stomach, or less than 1,5 mL/kg clear fluid in the gaster
High risk of aspiration	Immediately before intubation	Detection of solids, or more than 1,5 mL/kg clear fluid in the gaster
