Varady NH, et al. - From September 2017 to September 2018, researchers assessed 314 patients with knee and hip arthroplasty to evaluate the variation pattern of postoperative glucose values during the perioperative period and also to analyze the optimal time to check glucose levels to best estimate for hyperglycemia. They observed that majority of total joint arthroplasty (TJA) candidates were hyperglycemic postoperatively. They calculated the total number of hyperglycemic persons at three glucose thresholds: strict ≥ 126 mg/dL, intermediate ≥ 137 mg/dL, and lenient ≥ 180 mg/dL. They found 9 pm day on the day of the surgery to be the most sensitive time for detecting hyperglycemia in both diabetic and nondiabetic individuals.
