The main route of insulin injection is subcutaneous. This promotes slower absorption and is less painful.
Nursing Interventions in Insulin Therapy
Administer insulin at a 45-degree angle. Obese - 90-degree angle.
Nursing Interventions in Insulin Therapy
Do not massage injection site to prevent rapid absorption= hypoglycemia
Nursing Interventions in Insulin Therapy
Injections should be 1/2 inch apart within the anatomical area. Finish all sites in one anatomical area before going to another area.
Nursing Interventions in Insulin Therapy
Lipodystrophy - hard fatty masses in the subcutaneous layers
Nursing Interventions in Insulin Therapy
To prevent Lipodystrophy:
systemic rotation of the site of injection; reuse one site after at least 2 weeks
administer insulin at room temperature; cold insulin causes lipodystrophy
Nursing Interventions in Insulin Therapy
Gently roll vial in between the palms to redistribute insulin particles. Do not shake the vial; bubbles make it difficult to aspirate exact amount.
Nursing Interventions in Insulin Therapy
Storing insulin:
Prefilled insulin syringes = refrigerator; potent for 1 week
Vial will be used up in 30 days = kept at room temperature (otherwise, vial should be refrigerated)
Insulin should not be frozen or kept in direct sunlight
Nursing Interventions in Insulin Therapy
To mix insulin:
Remember: Draw up the regular insulin (clear) first!
Introduce air into the vial of intermediate-acting insulin. Do not aspirate or draw up the insulin yet
Introduce air into the vial of regular insulin, and draw up the insulin.
Draw up the NPH
Nursing Interventions in Insulin Therapy
Administer a mixed dose of insulin within 5 to 15 minutes of preparation; after this time the regular insulin binds with the NPH insulin and its action is reduced.
Complications of Insulin Therapy
Local allergic reactions
redness, swelling, tenderness, and induration or wheal at the site of injection
Management:
avoid alcohol
administer antihistamine one hour before injection as prescribed by the physician
Complications of Insulin Therapy
Insulin Lipodystrophy
Lipoatrophy - loss of subcutaneous fat
Lipohypertrophy - development of fibrous fatty masses
Management:
Rotate injection site
Complications of Insulin Therapy
Dawn Phenomenon
Increased blood glucose level between 5 and 8 AM
Management:
Delay Insulin - administer at 10 PM to control morning hyperglycemia
Complications of Insulin Therapy
Somogyi Phenomenon
Hypo glycemia occurs at 2-3 AM, which triggers production of counterregulatory hormones
By 5-6 AM, in response to the counterregulatory hormones, the blood glucose rebounds to hyper glycemic range
Management:
Decrease evening insulin
Give midnight snack
Complications of Insulin Therapy
Insulin Waning
progressive rise in the blood glucose level from bedtime to morning
