Patients with comorbidities that delay gastric emptying, such as diabetic gastroparesis,
neuromuscular disorders, morbid obesity, and advanced hepatic or renal disease, 
may potentially benefit from additional assessment via **gastric ultrasound scanner**(**
GUS**) before an elective procedure.

The main objective of **point-of-care** (**POC**) **gastric ultrasound** is to help
clinicians assess gastric contents when NPO status, which is unknown or uncertain
in the immediate pre-anesthetic period.

## Which ultrasound scanners do doctors use for gastric assessment?

It is important to acknowledge that a POC gastric ultrasound examination with the
[SIFULTRAS-5.42](https://sifsof.com/product/double-head-wifi-color-ultrasound-scanner-sifultras-5-42-fda/)
can conclusively rule in or rule out a clinical diagnosis.

 A curved array low-frequency transducer (2–5 MHz) with standard abdominal settings
is most useful in adults. It provides the necessary penetration to identify the 
relevant anatomic landmarks. A linear high-frequency transducer can be used in leaner
or paediatric patients or to obtain detailed images of the gastric wall. The gastric
wall is 4–6 mm thick and has a characteristic appearance of five distinct sonographic
layers that are best visualized with a high-frequency transducer (e.g. 5–12 MHz)
in the fasting state.

**Gastric US** can provide valuable insight into the nature and volume of gastric
content before performing a block with sedation or inducing anesthesia for an urgent
or emergent procedure where NPO status is unknown.

Hence to assess gastric content and volume to clinically evaluate aspiration risk
by providing qualitative and quantitative information.

 Other than **[anesthesiologists](https://sifsof.com/product-category/doctor-specialties/anesthesiologist/)**,**
POC** **gastric ultrasound** is also useful to **[emergency physicians](https://sifsof.com/product-category/doctor-specialties/emergency-medicine-specialist/)**
and **intensivists** who take part in sedation and airway management.
