Rules of mixing drugs of insulinRules of mixing drugs of insulin
1. Never mix crystal zinc-insulins of the 3d group (ultralente) with simple insulin because the Zn2+ partially transforms simple insulin to prolonged form. Therefore its absorption decreases and onset becomes longer. Insulins of these groups should be introduced separately, using different places for injection.
2. Insulin-zinc-suspensions should no be mixed with drugs that contain phosphates because due to this zinc phosphate is produced that leads to decreasing of duration action of zinc-insulins.
3. Never mix insulins with different pH level in one syringe. For example, acid insulins of short action aren’t combinable with NPH-insulins, and surphen –insulins should not be combined with neutral drugs with short action.
Indication for usage of insulin drugsIndication for usage of insulin drugs:: Patients with diabetes mellitusPatients with diabetes mellitus::
1. Absolutely indicated in case of diabetic coma and precoma.2. Diabetes mellitus of I type if diet therapy and other sugar
decreasing means aren’t enough effective. 3. Diabetes of any type if it is accompanied by complications
(ketoacidosis, infection, gangrene etc.)4. Surgeries, pregnancy.
Other casesOther cases::
5. In case of long-lasting exhausting illnesses.6. In case of heart, liver, kidney diseases the drugs are
administered with glucose or as a component of polarizing mixture.
7. Shock therapy of schizophrenia.

• intravenously dropplyintravenously dropply counting 0,1 О0,1 ОDD//kgkg of body weight per hourof body weight per hour. First two hours – with the speed of 8 ОD/hour. If the initial glycemia is higher than 33,3 mmol/lл insulin dose in first hour is increased till 16 OD. In case of decreasing of sugar level on 25-50 % from the initial level the speed of introduction of insulin is correspondingly decreased on 25-50 %. If glycemia is lower than 16,6 mmol/l insulin should be introduced with the speed of 4 OD/hour. In case of decreasing of sugar level lower than 11 mmol/l, it is recommended to transfer to subcutaneous introduction of the drug every 6-8 hours.
• Glycemia should not be decreased faster than 5 mmol/l/hour, otherwise it is possible to promote brain edema. The level of glycemia should be examined every 30-60 minutes.
2. Elimination of dehydration and hypovolemiadehydration and hypovolemia: intravenous dropping introduction of liquids: during 1st hour 1 l of 0,9 % NaCl (better – Ringer’s solution) is introduced, during the next 2 hours – 500 ml of 0,9 % NaCl each hour, and after not more than 300ml/hour. In case of decreasing of glycemia level lower than 14 mmol/l, 0,9 % NaCl should be substituted by 5-10 % glucose solution
3. Acidosis correctionAcidosis correction – solution of sodium hydrocarbonate (if pH lower than 7,1)
4. Correction of electrolyte disordersCorrection of electrolyte disorders: after 2 hours from beginning of treatment intravenous dropping introduction of КСІ dosed 2 g/hour should be started under the constant control of potassiumemia.
5. Symptomatic treatmentSymptomatic treatment: of correction of blood pressure only introduction of mesatone is possible, since other adrenomimetics stimulate glycogenolysis and increase sugar level in blood.
