A surgical patient experienced severe hyperglycemia during an abdominal aortic aneurysm repair. This event suggests a possible underlying insulin deficiency, unmasked by surgical stress and anesthesia.

Area of Science:

  • Endocrinology
  • Anesthesiology
  • Cardiovascular Surgery

Background:

  • Perioperative hyperglycemia is a common concern in surgical patients.
  • Abdominal aortic aneurysm (AAA) repair is a major surgical procedure associated with significant physiological stress.

Observation:

  • A 64-year-old male without a history of diabetes mellitus developed severe hyperglycemia (peak plasma glucose 43.2 mmol/L) during AAA repair.
  • The hyperglycemia resolved promptly following intravenous administration of 30 units of regular insulin.

Findings:

  • While surgical stress, medications, and isoflurane anesthesia contributed, they did not fully explain the extreme glucose elevation.
  • The patient's response suggests a potential underlying, previously undiagnosed insulin deficiency.

Implications:

  • This case highlights the importance of monitoring glucose levels in patients undergoing major surgery, even those without a prior diabetes diagnosis.
  • Unmasking of insulin deficiency during surgical stress may necessitate prompt insulin therapy.
  • Further investigation into pre-existing glucose dysregulation may be warranted in similar clinical scenarios.
