Postoperative Management of Diabetic Patients After Hysterectomy

Immediate Postoperative Period (First 24 Hours)

The American College of Anaesthesiologists recommends checking capillary blood glucose immediately and then every 1-2 hours during the acute postoperative phase, especially if on insulin therapy 1, 2, 3
Increase monitoring frequency if the patient is on insulin or insulin secretagogues due to risk of hypoglycemia unawareness 1, 2
For patients not previously on insulin with persistent hyperglycemia, start insulin at 0.5-1 IU/kg/day (half as basal insulin, half as rapid-acting analogue) 2, 3, 4

Check for ketosis immediately in any diabetic patient with significant hyperglycemia to rule out ketoacidosis 1, 2, 5
Measure serum electrolytes urgently if blood glucose >300 mg/dL to assess for hyperosmolar state, which requires ICU-level care 1, 2, 5
Initiate rapid-acting insulin analogue and ensure adequate hydration 1, 2, 3

Administer glucose immediately, even without clinical symptoms, if blood glucose <60 mg/dL 1, 2, 3
Prefer oral route (15-20g glucose) if patient is conscious and able to swallow 1, 2
Give IV glucose immediately if patient is unconscious or unable to swallow, then switch to oral when consciousness returns 1, 2, 3

Use 0.9% normal saline as primary IV fluid, especially given NPO status and surgical fluid losses 5
Ensure adequate hydration to prevent dehydration-related hyperglycemia 1, 2, 5

Continue basal insulin and add rapid-acting insulin with meals if insulin was started 1, 2, 3, 4
Adjust doses based on blood glucose patterns over 24-48 hours 1, 2
Consider transitioning back to OHAs only if pre-surgery glycemic control was adequate and current control is stable 1

Do not abruptly stop insulin if initiated, as this causes rebound hyperglycemia 5
Never ignore symptoms of confusion or altered mental status—check blood glucose immediately and consider hyperosmolar state in Type 2 diabetes 1, 2

Monitor vital signs, urine output, wound healing, and pain control per routine hysterectomy protocols 1
Ensure early mobilization when appropriate 1
