On the background of insulin therapy, a constant control of the concentration of glucose in the blood is necessary.
The causes of hypoglycemia in addition to an overdose of insulin may include: drug substitution, skipping meals, vomiting, diarrhea, increased physical activity, diseases that reduce the need for insulin (liver and kidney dysfunction, hypofunction of the adrenal cortex, pituitary gland or thyroid gland), change of injection site, as well as interaction with other drugs.
Incorrect dosing or breaks in the administration of insulin, especially in patients with type 1 diabetes, can lead to hyperglycemia. Usually the first symptoms of hyperglycemia develop gradually over several hours or days. They include the appearance of thirst, increased urination, nausea, vomiting, dizziness, redness and dryness of the skin, dry mouth, loss of appetite, odor of acetone in the exhaled air. If not treated, hyperglycemia in type 1 diabetes can lead to the development of life-threatening diabetic ketoacidosis.
The dose of insulin must be corrected in case of thyroid dysfunction, Addison's disease, hypopituitarism, liver and kidney dysfunction and diabetes mellitus in persons over 65 years of age.
Correction of the dose of insulin may also be required if the patient increases the intensity of physical activity or changes the habitual diet.
Concomitant diseases, especially infections and conditions accompanied by fever, increase the need for insulin.
Transfer of the patient to a new type of insulin or an insulin preparation of another manufacturer must be carried out under the supervision of a doctor.
Due to the possibility of precipitation in some catheters, the use of the drug in insulin pumps is not recommended.
Instructions to be given to the patient
Do not use the drug if a precipitate appears in the solution.
The technique of injection with the use of insulin in vials
If the patient uses only one type of insulin
1. Disinfect the rubber membrane of the vial.
2. Draw the air into the syringe in the volume corresponding to the desired dose of insulin. Insert air into the vial with insulin.
3. Turn the bottle with the syringe upside down and type the desired dose of insulin into the syringe. Remove the needle from the vial and remove air from the syringe. Check the correctness of the dose of insulin.
4. Immediately inject.
If the patient needs to mix two types of insulin
1.Disinfect the rubber membranes of the vials.
2. Directly before typing, roll a vial of long-acting insulin ("cloudy") between the palms until the insulin becomes evenly white and cloudy.
3. Draw the air into the syringe in a volume corresponding to the dose of "cloudy" insulin. Enter the air into the vial with the "turbid" insulin and remove the needle from the vial.
4. Insert the air in the syringe in the amount corresponding to the dose of insulin of short action ("transparent"). Insert air into the bottle with "transparent" insulin. Turn the bottle with the syringe upside down and type the desired dose of "transparent" insulin. Remove the needle and remove air from the syringe. Check the correctness of the dialed dose.
5. Insert the needle into the vial with "cloudy" insulin, flip the bottle with the syringe upside down and type the desired dose of insulin. Remove air from the syringe and check the correctness of the dialed dose. Immediately make an injection of the dialed mixture of insulin.
6. Always take the insulin in the same sequence described above.
Injection procedure
- It is necessary to disinfect the area of the skin where insulin will be injected.
- With two fingers, assemble the skin fold, insert the needle into the base of the fold at an angle of about 45 degrees and insert insulin under the skin.
- After the injection, the needle should remain under the skin for at least 6 seconds, in order to ensure that the insulin is injected completely.
- If after removing the needle at the injection site, blood appears, gently press the site of the injection with a swab moistened with disinfectant solution (for example, alcohol).
- It is necessary to change the injection site.
