Gastric Ultrasound Course

A 7-hour 25-minute course on point-of-care gastric ultrasound and its role in preventing pulmonary aspiration at induction of general anaesthesia/sedation.

Faculty

Dr. Başak Ceyda Meço — Safe Brain Initiative concept and precision medicine (opening lecture)
Massimo Lamperti — Gastric ultrasound theory, decision pathway, and hands-on workshop lead
Dr. Özgür Demir — Risk stratification. GLP-1 RA-related delayed gastric emptying.
Hands-on sessions: Massimo Lamperti, Özlem Selvi Can, Süheyla Karadağ Erkoç, Gökçen Emmez, Ayşegül Güven, Nur Duruk Erkent, Sait Bilgiç, Fatih Kurt, Ekin Kutlu

Course Learning Objectives

Describe the sonographic anatomy of the gastric antrum and the scanning technique in the right lateral decubitus position (RLDP).
Apply the Perlas qualitative grading system (Grade 0/1/2) to classify gastric content.
Calculate estimated gastric volume using the semiquantitative Perlas model and antral cross-sectional area (CSA).
Explain the evidence base behind the 2025 ESAIC preoperative assessment guideline recommendation on gastric ultrasound and the new evidence on 2027 ESAIC guidelines on fasting in adults.
Integrate gastric ultrasound findings into the pre-induction decision pathway for patients at risk of a full stomach (including GLP-1 receptor agonist users).
Recognise common pitfalls, artifacts, and scanning limitations.

Hands-On Session — Detail

Format: 4 rotating stations, ~30 minutes each, small groups of 4–5 participants per volunteer/machine. Each station uses either a volunteer or curated image/video cases to demonstrate different gastric contents and scanning challenges.

Station A — Scanning Technique & Landmarks

Volunteer status: fasted (>8 h solids, >2 h clear fluids) → expected empty antrum (Grade 0).

Supine and RLDP positioning; probe placement in the epigastric sagittal plane.
Identifying landmarks: liver left lobe, pancreas, aorta, superior mesenteric artery/vein, antrum — the “bull's-eye”/“target sign” appearance.

Station B — Qualitative Grading (Low Volume)

Volunteer status: standardized clear fluid load (e.g. 300 mL water) ingested ~30 min prior → expected Grade 1 (fluid visible in RLDP only).

Applying the Perlas 3-point qualitative scale.
Distinguishing clear fluid contents from an empty antrum.

Station C — Semiquantitative Volume Estimation (Higher Risk)

Volunteer status: standardized light solid test meal or larger fluid volume ingested a few hours prior → expected Grade 2 (contents visible supine and in RLDP).

Antral cross-sectional area (CSA) measurement in RLDP.
Applying the Perlas mathematical model to estimate gastric volume (mL/kg) and risk category.

Station D — Pitfalls, Artifacts & Special Populations

Case-based station using the volunteer plus a curated image/video library (live scanning of pregnancy positioning or obesity is not always feasible with healthy volunteers).

Differentiating solid particulate content, air artifact, and true fluid on echotexture.
Limitations: obesity, pregnancy, prior gastric surgery, poor patient cooperation.
