Aspiration Pneumonia, Gastric Volume
Conditions
Brief summary
ASA fasting guidelines are only applicable to healthy elective surgery patients. Measuring gastric volume now is not easy, and scintigraphy has remained the gold standard technique for many years. This prospective observational study aim to explore the gastric emptying of type 2 diabetic patients.
Detailed description
ASA fasting guidelines are only applicable to healthy elective surgery patients. Measuring gastric volume now is not easy, and scintigraphy has remained the gold standard technique for many years. Ultrasound has progressively emerged as a useful substitute due to its reduced cost and ease of performance. Using gastric ultrasound measure gastric antrum cross-sectional area to determine whether patients are empty stomach, help anesthesiologists in preoperative evaluation of diabetic patients with the risk of aspiration, so as to guide the anesthesiologist take effective interventions, this prospective observational study aim to explore the gastric emptying of type 2 diabetic patients.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Gastric contents | before anesthesia | using ultrasound to evaluate antral cross-sectional area |
| Risk factors | before anesthesia | by analysisng full stomach of patients to find risk factors |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Perlas grading scale | before anesthesia | This is a 3-point grading system (grades 0, 1, and 2) based exclusively on qualitative sonographic assessment of the gastric antrum.If a patient's antrum appears empty in both supine and right lateral positions (grade 0), it is likely truly empty. If it appears only mildly distended in the right lateral decubitus position, but not in the supine position (grade 1), the patient likely has a very small volume of gastric fluid within the limits of what is known to be safe. An antrum that is distended in both supine and right lateral decubitus positions (grade 2) denotes a gastric fluid volume beyond the limits of what is considered safe. |
