研究概览
简要总结
The goal of this observational study is to assess the preoperative gastric residual volume in adult patients undergoing elective surgery. The main question it aims to answer is:
Does gastric residual volume, content type, and aspiration risk differ between diabetic and non-diabetic patients with similar fasting durations?
Participants undergoing elective surgery will receive bedside gastric ultrasound as part of their preoperative assessment. Ultrasound images will be used to estimate gastric volume and evaluate aspiration risk.
详细描述
The goal of this observational study is to assess whether bedside gastric ultrasound can identify differences in residual gastric volume, content type, and aspiration risk in adult diabetic and non-diabetic patients (ages 18-65) undergoing elective surgery under general anesthesia.
The main questions it aims to answer are:
Do diabetic patients have higher residual gastric volume than non-diabetic patients despite similar fasting durations?
Does the type or amount of gastric content differ between the two groups, potentially increasing aspiration risk?
Researchers will compare diabetic and non-diabetic groups to see if diabetes is associated with delayed gastric emptying and increased aspiration risk.

结局指标
主要结局
Residual gastric volume (mL) measured by bedside ultrasound in diabetic vs. non-diabetic patients.
时间窗: Immediately before induction of anesthesia (preoperative period)
The main question of the study is whether gastric emptying is delayed in diabetic patients, resulting in a higher residual gastric volume.
