In a select group of patients, use of an insulin pump may improve glycemic control while enhancing patient convenience. These devices can be programmed to infuse varying basal and bolus levels of insulin, which change smoothly even while the patient sleeps or is otherwise preoccupied.

The effectiveness of continuous subcutaneous insulin infusion in pregnancy is well established. [78, 79] Hieronimus et al reported similar HbA1C levels, macrosomia rates, and cesarean rates in 33 pregnant women managed with insulin pump, compared with 23 receiving multiple insulin injections,. [80] Lapolla et al found no differences in glycemic control or perinatal outcome between 25 women treated with insulin pump in pregnancy and 68 women who received conventional insulin treatment.
