Glycemic Variability in Postoperative Major Oncosurgery Patients and its Effect on Patient Outcomes - A Prospective Observational Study

We conducted the study for evaluating effect of glycemic variability in postoperative major oncosurgery patients. We collected data for 104 patients (February, 2017 to December, 2018) with gastrointestinal neoplasm undergoing surgery for more than 4 hours. We used iProTM 2 Continuous Glucose Monitoring System to collect values for Mean and Standard Deviation of glucose within 24 hours (Glu1Ave and Glu1SD) and Maximum glucose, Mean glucose, Standard Deviation of glucose, Coefficient of variance of glucose in 72 hours (GluMax, GluAve, GluSD and GluCV). The association of GluSD, GluCV and Glu1SD with mortality and morbidity was statistically significant irrespective of diabetic status.
