Summary
High preoperative hemoglobin A1C (HbA1c) levels are linked to worse outcomes in gynecologic surgery. This review offers subspecialty guidelines for perioperative glycemic control to improve patient results.
Area of Science:
- Gynecology
- Endocrinology
- Surgical Oncology
Background:
- Consensus on perioperative glycemic control in gynecologic (GYN) surgery is lacking.
- Optimizing blood glucose levels is crucial for improving surgical outcomes.
Purpose of the Study:
- To review current literature on glycemic control and postoperative outcomes in major GYN surgery.
- To establish evidence-based guidelines for perioperative hemoglobin A1C (HbA1c) goals across GYN subspecialties.
Main Methods:
- A comprehensive literature search was conducted across PubMed, Embase, and Web of Science.
- Included peer-reviewed studies published from 1990 to the present, focusing on major GYN surgeries and postoperative complications.
- Extracted data included study design, patient demographics, surgical procedures, complications, and glycemic control measures.
Main Results:
- Analysis of 14 studies revealed associations between elevated HbA1c and adverse outcomes.
- In benign GYN surgery, HbA1c >9% correlated with surgical site infections (SSIs).
- Urogynecology patients with HbA1c >8% faced increased urinary tract infections and wound complications.
- GYN oncology patients with HbA1c ≥7% showed reduced survival rates; elevated preoperative glucose also increased risks for DVT and SSI.
Conclusions:
- Elevated preoperative HbA1c is a significant predictor of poorer postoperative outcomes in major GYN procedures.
- Specific HbA1c thresholds are associated with increased complications across benign, urogynecologic, and oncologic GYN surgery.
- Guidelines are proposed to aid clinicians in optimizing perioperative glycemic control for improved patient management.

01:29Hyperglycemia
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...
01:15Hypoglycemia 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...
01:22Diabetes 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...

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
01:28Cardiomyopathy VII: Pre and Post Operative Nursing Management
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
01:26Hypoglycemia
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...
