What is the recommended glucose range for patients during perioperative phases?

60-100 mg/dl
70-140 mg/dl
80-180 mg/dl
100-200 mg/dl

The correct answer is: 80-180 mg/dl

The recommended glucose range for patients during perioperative phases is 80-180 mg/dl because maintaining blood glucose levels within this range is crucial for optimal patient outcomes. Elevated glucose levels can impair wound healing, increase the risk of infection, and lead to complications post-surgery, particularly in patients with diabetes or other metabolic disorders. The range of 80-180 mg/dl strikes a balance, allowing for acceptable glycemic control without risking the hypoglycemia that might occur at lower glucose thresholds. This target range is often emphasized in guidelines to enhance surgical recovery and minimize risks during and after the surgical process. In contrast, ranges that are too low, like 60-100 mg/dl, may increase the risk of hypoglycemic events, while higher ranges, such as 100-200 mg/dl, do not adequately address the risks associated with elevated glucose levels in the perioperative setting. Therefore, the 80-180 mg/dl range is suggested to optimize patient safety and recovery.
