Sugar and insulin combo may reduce surgery risks in Non-Diabetics
NCT ID NCT06624956
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tested whether giving a mix of glucose, insulin, and potassium (GIK) during abdominal surgery can reduce serious complications in patients who do not have diabetes. About 106 adults took part to see if the treatment is practical and safe. The goal is to plan a larger study to confirm if GIK helps prevent harm from high blood sugar during surgery.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Adults 18 years of age or older 2. Patients undergoing abdominal surgery planned to last greater than 4 hours with inpatient admission 3. Patients at UWMC - Montlake 3\. Makes their own medical decisions: patient is deemed to have decisional capacity by the medical team and does not have a surrogate such as a spouse, partner, or caretaker making the decision on their behalf. Examples include patients with severe dementia or other cognitive limitations Exclusion Criteria: 1. Known diagnosis of diabetes or altered glucose homeostasis during preoperative evaluation (single fasting blood sugar≥126 mg/dL or HbA1C≥6.5 percent). 2. Known diagnosis of chronic kidney disease (moderate-to-severe, or worse) * BMP within 6 months of screening is required. Patients with stage 3b (moderate-to-severe) kidney disease or worse (i.e. eGFR ≤ 30) will be excluded. Patients with a potassium reading greater than 5.5 at any point within the 6-month period will also be excluded. 3. Patients receiving chronic systemic steroids. 4. Patients undergoing cardiac or solid organ transplant procedures. 5. Surgery planned to last less than 4 hours. 6. Outpatient surgery 7. Pregnant people 8. Current UW Medicine or UW Dentistry residents and fellows 9. Known hypersensitivity to potassium, glucose, insulin, or any of its excipients. 10. Enrollment in another therapeutic study 11. Any serious underlying medical or psychiatric condition, dementia, altered mental status or any issue that would impair the ability of the patient to receive or tolerate the planned treatment, to understand informed consent or that in the opinion of the investigator would contraindicate the patient's participation in the study or that would confound the results of the study.
