研究目的:

本研究采用前瞻性双队列研究,拟招募健康志愿者与门诊患者双队列,其中健康志愿者通过模拟空腹、液体摄入(500mL 水)、固体摄入(200g 汉堡)及混合摄入(300mL 水 + 200g 汉堡)场景,门诊患者在胃镜检查前服用不同剂量消泡剂(20-60mL)后,运用自主开发的 AI 辅助诊疗系统胃容积评估模块,结合超声检查评估胃容积,并与传统评估方法(Perlas 数学模型、《Gastric Ultrasound》评估表格)对比,验证 AI 系统在健康人群不同胃内容物负荷及门诊患者消泡剂干预场景下评估胃容积的准确性与可靠性,为 AI 技术在围术期及消化疾病诊疗中的无创精准评估提供依据,推动智能超声技术的临床转化。  

Objectives of Study:

This study employs a prospective dual-cohort design, intending to recruit both healthy volunteers and outpatient cohorts. Healthy volunteers will simulate scenarios including fasting, liquid intake (500 mL water), solid intake (200 g hamburger), and mixed intake (300 mL water + 200 g hamburger). Outpatient patients will be administered different doses of defoaming agents (20-60 mL) prior to gastroscopy. The self-developed AI-assisted diagnosis and treatment system's gastric volume assessment module will be utilized, combined with ultrasound examination, to evaluate gastric volume. This will be compared against traditional assessment methods (the Perlas mathematical model and the "Gastric Ultrasound" evaluation form) to validate the accuracy and reliability of the AI system in assessing gastric volume under different intragastric content loads in healthy populations and under defoaming agent intervention scenarios in outpatient patients. This aims to provide evidence for the application of AI technology in non-invasive precise assessment during the perioperative period and in the diagnosis and treatment of digestive diseases, thereby promoting the clinical translation of intelligent ultrasound technology.

随机方法(请说明由何人用什么方法产生随机序列):

采用简单随机化设计,由一名独立统计人员使用R软件生成随机序列。将60名符合入排标准的健康志愿者按1:1:1比例随机分配至A、B、C三组;同时,将60名拟行胃镜检查的门诊患者采用相同的R软件简单随机化方法,按1:1:1比例分配至A、B、C三组,每组各20例。

Randomization Procedure (please state who generates the random number sequence and by what method):

The random allocation sequence was generated by an independent statistician using the R software . A simple randomization procedure was employed for both cohorts. Specifically, 60 eligible healthy volunteers were randomly assigned in a 1:1:1 ratio to the three intervention groups (Group A, B, and C). Similarly, 60 eligible outpatients scheduled for gastroscopy were also randomly allocated in a 1:1:1 ratio to the three corresponding groups (Group A, B, and C), with 20 participants in each group.
