Insights

Glycosylated hemoglobin (HbA1c) levels can predict perioperative glucose control in patients with type 2 diabetes undergoing surgery. This finding suggests HbA1c may serve as a biomarker for immediate glucose management during the perioperative period.

Area of Science:

  • Endocrinology
  • Perioperative Medicine
  • Diabetes Management

Background:

  • Hyperglycemia and elevated glycosylated hemoglobin (HbA1c) are linked to increased perioperative morbidity in diabetic patients.
  • The relationship between long-term glycemic control (HbA1c) and perioperative glucose fluctuations remains unclear.

Purpose of the Study:

  • To investigate the association between HbA1c levels and perioperative glucose control.
  • To determine if HbA1c can predict glucose levels before and after elective non-cardiac surgery in fasting type 2 diabetes patients.

Main Methods:

  • Prospective observational study involving 244 adult patients with type 2 diabetes.
  • Preoperative HbA1c levels were measured.
  • Preoperative and postoperative blood glucose values were recorded on the day of surgery.

Main Results:

  • 50% of patients had an HbA1c level of 7% or higher; 23% had an HbA1c of 8% or higher.
  • HbA1c levels effectively predicted preoperative glucose levels.
  • Preoperative glucose levels and surgery duration predicted postoperative glucose levels.
  • One-third of patients experienced a decrease in glucose levels during surgery without intervention.

Conclusions:

  • HbA1c levels may function as valuable biomarkers for assessing glucose control in the immediate perioperative period.
  • This highlights the potential utility of HbA1c in managing diabetic patients undergoing elective surgery.

Hyperglycemia01:29

Hyperglycemia

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...
Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
Hypoglycemia01:26

Hypoglycemia

Hypoglycemia is a blood glucose level below 70 mg/dL. It commonly occurs in individuals using insulin or insulin-secreting drugs, but may also arise in non-diabetic conditions. People with type 1 diabetes are at the highest risk because they depend on exogenous insulin. People with type 2 diabetes are also at risk, especially when treated with insulin or medications such as sulfonylureas, which increase insulin release regardless of blood glucose levels. It develops when insulin levels exceed...
Hormones Regulating Blood Glucose01:16

Hormones Regulating Blood Glucose

Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...
Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
