- Original description
Diabetes can slow down stomach emptying. As a result, some patients with diabetes may still have food or fluid in their stomach before surgery, even after following standard fasting rules. This can increase the risk of stomach contents entering the lungs (pulmonary aspiration) during anesthesia.Read full original descriptionShow less
Distribution of Residual Gastric Volume Assessed by Preoperative Gastric Ultrasound, Aspiration Risk, and Related Factors in Diabetic Patients Undergoing Elective Surgery: A Prospective Observational Study
Diabetes can slow down stomach emptying. As a result, some patients with diabetes may still have food or fluid in their stomach before surgery, even after following standard fasting rules. This can increase the risk of stomach contents entering the lungs (pulmonary aspiration) during anesthesia.
The aim of this prospective observational study is to measure the amount of residual stomach content using bedside gastric ultrasound in adult patients with type 1 or type 2 diabetes scheduled for elective surgery under general anesthesia. The study will also determine how often a high aspiration risk is present and identify clinical factors associated with it, including HbA1c level, duration of diabetes, use of GLP-1 receptor agonists, insulin use, fasting duration, and gastroparesis symptoms.
Gastric ultrasound is non-invasive, painless, and does not involve radiation. No drug or additional intervention will be given as part of this study. Patients found to be at high aspiration risk will be reported to the responsible anesthesiologist.
Inclusion: Age 18-80 years; Diagnosis of type 1 or type 2 diabetes mellitus; Scheduled for elective surgery under general anesthesia; ASA physical status I-III; Written informed consent.
Exclusion: Emergency surgery; History of upper gastrointestinal surgery; Pregnancy; Known gastrointestinal obstruction; Known severe gastroparesis; Inadequate gastric ultrasound image quality; Refusal to provide consent.
