Following a cesarean birth, how should the insulin infusion of a diabetic woman be managed?

Following a cesarean birth, it is essential to adjust the insulin infusion for a diabetic woman due to the physiological changes that occur during and after surgery. During the perioperative period and immediately following the cesarean delivery, the body experiences increased levels of stress hormones, such as cortisol and adrenaline, which can impact blood glucose levels.

Reducing the insulin infusion by 50% is a strategy used to prevent hypoglycemia while still providing adequate insulin coverage. This reduction accounts for the decreased dietary intake that commonly occurs immediately postoperatively, as the patient may not resume eating solid foods for a while.

Maintaining the pre-delivery level of insulin could lead to hypoglycemia, especially since the woman's nutritional intake is limited after surgery. Stopping the insulin infusion and restarting subcutaneous insulin may not adequately address her immediate insulin needs, potentially leading to hyperglycemia or other complications. Increasing the insulin infusion due to stress hormones could lead to overshooting blood glucose control and necessitate careful monitoring.

Thus, decreasing the insulin infusion by 50% aligns with best practices for managing diabetes in the postoperative period after cesarean delivery.
