测量指标:

Outcomes:

指标中文名:

饱胃患者发生率

指标类型:

主要指标

Outcome:

Incidence of full stomach patients

Type:

Primary indicator

测量时间点:

在患者入室后立即进行胃超声检查

测量方法:

所有受试者首先处于仰卧位进行胃超声检查,随后转为右侧卧位再次进行胃超声检查,在右侧卧位在腹主动脉与下腔静脉截面分别储存三个胃收缩间期的图像,使用描迹法(包含胃壁浆膜层)测量胃窦横截面积取平均值。

Measure time point of outcome:

Gastric ultrasound was performed immediately upon the patient's arrival in the operating room.

Measure method:

All subjects underwent initial gastric ultrasonography in the supine position, followed by a subsequent examination in the right lateral decubitus (RLD) position. In the RLD position, three images were captured during gastric relaxation (between contractions) at the level of the abdominal aorta and inferior vena cava. The gastric antral cross-sectional area (CSA) was measured using the free-tracing method (including the serosal layer), and the average value of the three measurements was recorded
