The development of hyperglycemia, which occurs in 10–88 percent of hospitalized patients getting TPN therapy, can be linked to the increased risk of problems during TPN therapy, among other variables (4-6). Hyperglycemia is a common problem for any patient receiving intensive care treatment, but it is especially important that health care providers watch patients who are being treated with TPN to prevent these complications from occurring. Patients who receive TPN often develop hyperglycemia because their body cannot use insulin properly when they are unable to absorb nutrients through their intestines. As a result, they may require higher doses of insulin to control their blood sugar levels. Health care professionals may need to adjust the dose of insulin given via IV or IM injection or put them on a special diet when treating patients with TPN-induced hyperglycemia. Healthy individuals who receive TPN should have blood tests done regularly to make sure they do not develop complications from the treatment. These tests will help doctors know how well their treatments are working and if they need to change or add anything to the regimen. Doctors will usually monitor blood glucose levels of patients receiving TPN. If necessary, they can give injections of insulin to lower those levels. Otherwise, they can place patients on a special diet to reduce the amount of food-based sugars entering their bodies while they receive the infusion.
