Meglitinides


 

Nateglinide, Repaglinide


  Issues for Surgery


Increased risk of post-operative infection and delayed wound healing due to poor glycaemic control if omitted.

Hypoglycaemia if continued during nil by mouth (NBM) period.


  Advice in the Perioperative period


Elective Surgery

Meglitinides should be taken as normal the day prior to surgery1.

Morning Surgery
Omit morning dose if nil by mouth1, 2.


Afternoon Surgery
Take morning dose if eating1, 2.

Emergency Surgery

In the event of emergency surgery and the patient has already taken their meglitinide dose monitor blood glucose levels closely and treat any hypoglycaemia accordingly.

Perioperative Considerations

Commence variable rate intravenous insulin infusion (VRIII) perioperatively where indicated (see Further Information) and omit meglitinide during VRIII treatment1.

Ensure emergency treatment of hypoglycaemia is prescribed i.e. Glucogel® and 20% dextrose. Rapid acting insulin should also be prescribed1, 2.

Post-operative Advice

Restart once eating and drinking normally and VRIII (where applicable) has been stopped1.


  Interaction(s) with Common Anaesthetic Agents

 

None2, 3, 4.


  Interaction(s) with other Common Medicines used in the Perioperative Period


Non-Steroidal Anti-inflammatory Drugs (NSAIDs)

Caution with concomitant use of NSAIDs – may enhance the hypoglycaemic effect of meglitinides3, 4, 5.


  Further Information


VRIII

Patients with a planned short starvation period (no more than one missed meal in total) should be managed by modification of their usual diabetes medication, avoiding VRIII wherever possible. Patients expected to miss more than one meal should have VRIII1.
