Gastric conditions / primarily focusing on preoperative anesthesia assessment for patients with a full stomach, evaluation of reduced gastric motility, abdominal distension, and the reduction of the risk of regurgitation and aspiration during anesthesia.
Conditions
Interventions
Control Group:Participants practice and observe gastric ultrasound under four gastric content conditions: fasting, water, milk, and meat bun.
Trial Group:All participants start fasting and sequentially consume 100ml water, 100ml milk, and one meat bun to dynamically build and observe a model of gastric content changes.
