Diabetes Mellitus (DM) and hyperglycemia are critical considerations in
the perioperative management of surgical patients. Elevated blood glucose
levels can lead to complications including increased infection risk, delayed
wound healing, and other adverse surgical outcomes. This article aims to
discuss the importance of effective perioperative management strategies
for diabetic patients, including preoperative assessment, intraoperative
care, and postoperative protocols. We explore the latest evidence-based
practices for optimizing glycemic control, the role of insulin therapy, and
the implications of different surgical procedures on blood glucose levels.
Emphasis is placed on tailoring these management strategies based on
patient individualization to mitigate risks and enhance surgical outcomes.

Diabetes Mellitus (DM) is a global health challenge characterized by chronic hyperglycemia resulting from insulin resistance, inadequate insulin secretion, or both (American Diabetes Association, 2020). As the prevalence of diabetes increases worldwide, the incidence of surgical procedures among diabetic patients also rises. Poorly controlled blood glucose levels during the perioperative period can result in significant morbidity, including heightened infection risk, increased rates of cardiovascular events, and delayed recovery. Therefore, a comprehensive understanding of the perioperative management of diabetes and hyperglycemia is essential for healthcare providers involved in surgical care [1].
Perioperative management of diabetes involves a multifaceted approach that spans preoperative, intraoperative, and postoperative phases, each requiring specific considerations for effective blood glucose control.
Preoperative Assessment
Glucose control: Prior to surgery, an assessment of the patient's glycemic control is essential. Patients with HbA1c levels above 7% are at a higher risk for postoperative complications and should ideally have their diabetes optimized before surgery.
Medication review: Patients on oral hypoglycemic agents or insulin need thorough evaluation. Certain medications, such as metformin, may need to be withheld in specific surgical contexts, particularly those that involve the potential for renal impairment or the use of contrast agents [2,3].
Diet and lifestyle: Dietary modifications aimed at stabilizing blood glucose levels should be discussed, ensuring patients understand the importance of carbohydrate intake in relation to their anticipated fasting periods.
Risk assessment: Identification of additional risk factors, including the type of surgical procedure, duration of surgery, and patient's comorbidities, will guide the perioperative management plan [4].
Intraoperative Management
Monitoring blood glucose levels: Continuous glucose monitoring or frequent blood glucose checks should be initiated during the intraoperative phase. It is vital to maintain blood glucose levels between 140-180 mg/dL.
Insulin administration: Subcutaneous or intravenous (IV) insulin may be necessary to achieve glycemic control. The choice between subcutaneous and IV insulin depends on the patient's previous insulin regimen and the anticipated complexity of the surgery. IV insulin is preferred in major surgeries due to its rapid onset and effectiveness.
Glucose infusions: In cases where patients are unable to eat, intravenous dextrose can help maintain glycemic control and prevent hypotension related to insulin use [5].
Postoperative care
Blood glucose monitoring: Close monitoring should continue postoperatively, with regular checks for the first 24-48 hours following surgery.
Adjustment of insulin regimens: Patients previously on insulin may require adjustments based on dietary intake and the surgical stress response. Frequent reassessment allows for timely changes to therapy.
Educational reinforcement: Employing diabetes educators or dieticians to reinforce lifestyle modifications, medication adherence, and self-monitoring techniques is beneficial for long-term management [6].
Studies indicate that optimized glycemic control significantly reduces postoperative complications. A retrospective review of diabetic patients undergoing surgery showed that tight glucose control resulted in a decrease in nosocomial infections, shorter ICU stays, and overall reduced morbidity (Fisher et al., 2021). Another study indicated that maintaining blood glucose levels below 180 mg/dL during the perioperative period can lower the risk of major cardiovascular events (Cleveland Clinic, 2021) [7].
The management of diabetes and hyperglycemia in the perioperative setting demands a collaborative approach among surgical teams, endocrinologists, and nursing staff. Risk stratification plays a critical role in determining the necessary interventions before surgery.
Intraoperatively, the engagement of continuous glucose monitoring and IV insulin protocols allows for fine-tuning of blood glucose levels under surgical stress, ensuring patients maintain stable glycemic control throughout the procedure.
Postoperative complications remain a significant concern, with hyperglycemia being a key indicator of potential adverse outcomes. Evidence supports that targeting a glucose range of 140-180 mg/dL reduces complications, though this can vary based on individual patient factors and surgical interventions [8-10].
Understanding the interplay between diabetes management and surgical outcomes is vital. A holistic approach considering patient-specific factors leads to tailored management strategies that improve care, outcomes, and overall patient satisfaction.
The perioperative management of diabetes mellitus and hyperglycemia is crucial for optimizing surgical outcomes and minimizing complications. A structured approach emphasizing careful preoperative assessment, intraoperative glucose management, and diligent postoperative care can enhance recovery and patient safety. With increasing surgical volumes in diabetic patients, healthcare providers must remain vigilant in employing evidence-based practices and individualized care plans that ensure optimal perioperative glycemic control. Future research should continue to focus on advancing clinical guidelines and tools to enhance diabetes management in surgical settings.
