研究目的: |
主要目的:使用超声测量空腹受试者饮用不同负荷量清液体后即时的胃内容量,比较在不同容量负荷下Perlas和Rong两公式的预测值与实际饮水量之间的误差和两公式估计值之间的差异。 次要目的:Perlas 和Rong 两公式在特定风险阈值下对“高风险胃”的判别能力。 |
||||||||||||||||||||||
|
Objectives of Study: |
Primary objective: To use ultrasonography to measure gastric volume immediately after fasting participants ingest different volumes of clear fluids, and to compare the errors between the predicted values derived from the Perlas and Rong formulas and the actual ingested volumes under different fluid loads, as well as the differences between the estimates generated by the two formulas. Secondary objective: To evaluate the discriminative performance of the Perlas and Rong formulas in identifying a "high-risk stomach" at predefined risk thresholds. |

随机方法(请说明由何人用什么方法产生随机序列): |
由固定的项目人员采用年龄(18岁≤年龄<60岁、60岁≤年龄≤85岁)分层的区组随机化设计,通过SPSS生成随机数字表,按“分层到区组”顺序将受试者按照1:1:1的比例随机分配至不同容量摄入组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
A designated study staff member implemented a stratified block randomization design based on age (18 ≤ age < 60 years; 60 ≤ age ≤ 85 years). A random number table was generated using SPSS, and participants were randomly allocated in a 1:1:1 ratio to different fluid volume intake groups according to the sequence of "stratification to block randomization." |

|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data were collected using a case report form (CRF), and data management was conducted via an electronic data management system (EDMS). A single researcher was responsible for data aggregation and classification, which were compiled into a data summary table and stored for subsequent analysis. |
