Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Participants will:

Undergo bedside gastric ultrasound prior to anesthesia induction

Be scanned in semi-sitting and right lateral decubitus positions using a convex ultrasound probe

Have gastric antrum graded and volume calculated

Be evaluated for aspiration risk based on validated ultrasound criteria

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Diabetic Group - Patients with a diagnosis of diabetes mellitus Non-Diabetic Group - Patients witho

Diabetic Group Adult patients (aged 18-65) with a known diagnosis of diabetes mellitus who are scheduled for elective surgery under general anesthesia.

These participants will undergo preoperative bedside gastric ultrasound to evaluate residual gastric volume, content type, and aspiration risk.

Non-Diabetic Group Adult patients (aged 18-65) without diabetes mellitus, scheduled for elective surgery under general anesthesia.

These participants will also undergo preoperative bedside gastric ultrasound for the same assessments as the diabetic group.

No interventions assigned to this group
