Evaluation of Early Postoperative Period Results of Patients With Type 2 Diabetes Taking Oral Anti-Diabetics Or Insulin Medications, With Microalbuminuria and Normal Creatinine Levels After Coronary Artery Bypass
Keywords:Type 2 diabetes mellitus, insulin, oral antidiabetic, coronary artery bypass
Background: Acute kidney injury (AKI) is one of the most important complications after cardiac surgery and is one of the main causes of morbidity and mortality. Diabetes mellitus also is one of the main risk factors for renal dysfunction in coronary artery bypass graft (CABG). In this study, we aimed to compare the early postoperative period results of type 2 diabetes patients taking oral antidiabetics (OAD) or insulin medications, with microalbuminuria and normal creatinine levels after CABG.
Methods: Eighty patients with type 2 diabetes and taking OAD or receiving insulin medication all with normal creatinine levels with microalbuminuria were included in this study. Preoperative creatinine values of the patients, albumin levels in spot urine, creatinine levels on the postoperative 3rd day, duration of ventilation, amount of drainage, length of stay in the intensive care unit, length of stay in the hospital, mediastinitis, and mortality rates were recorded.
Results: A statistically significant increase in creatinine was found in both taking OAD type 2 diabetes and insulin medication with microalbuminuria. When the two groups were compared with each other, the increase in creatinine levels of the patients using insulin was higher than the patients taking OAD. It also was statistically significant.
Conclusion: According to the result of our study, it can be suggested that postoperative creatinine elevation is observed in patients with type 2 diabetes mellitus with microalbuminuria and with normal creatinine levels, either having insulin medication or not. The elevation is higher in patients having insulin medication, while other results are similar, except for impaired renal function.
