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

University Hospital, Akershus

Status: Completed

Conditions: Rapid Sequence Intubation; Non-fasting Patients; Anesthesia Intubation Complication

Treatments: Other: Bedside ultrasound

Study type: Observational

Funder types: Other

Identifiers

NCT03685435

2018/1560

Details and patient eligibility

About

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.

Full 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.

Enrollment: 72 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• adults scheduled for surgery
• Adults over 18 years old that are assigned to general anesthesia with rapid sequence intubation (RSI)

Exclusion criteria

• Body mass index over 40
• Pregnant women
• Patients earlier underwent gastric surgery
• Critically ill patients where spending time on ultrasound would cause a major disadvantage for the patients

Trial design

72 participants in 1 patient group

Non-fasting patients

Description:

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.

Treatment:

Other: Bedside ultrasound
