Acute complications associated with the use of insulin infusion pumps

Because insulin pump therapy is capable of providing insulin both at a slow continuous basal rate and in boluses, it more closely approximates physiologic insulin secretion than is possible with other methods of insulin administration. However, several short-comings are specifically related to the way insulin is delivered by pumps. These include increased risk of diabetic ketoacidosis and increased likelihood of infection at injection sites. The risk of hypoglycemic coma is apparently no greater with pump therapy than with conventional injections. Health professionals using pump therapy need a good working knowledge of the technical details as well as of the risks and benefits, and must be prepared to provide comprehensive training to their patients, particularly in the practice of frequent self-monitoring of blood glucose levels.
