Precautions：
1.Disinfection method: 75% alcohol is used to disinfect the skin for insulin injection, and the skin is allowed to dry before injection.
2.Injection method: According to the length of the needle, choose whether to pinch the skin, ≤5 mm does not need to pinch the skin. If you need to pinch the skin, pinch the skin and insert the needle at a 90-degree angle; There is less subcutaneous fat, and the needle is inserted at a 45-degree angle. After the injection, leave on for 10 seconds before pulling out.
3.Injection site rotation: Divide the injection site into four quadrants, use one quadrant per week and rotate in a clockwise direction, with each injection at least 1 cm away from the last injection.
4.Needles: Insulin pen needles are injected once at a time.
5.Exhaustion: For newly installed insulin refills, pay attention to ventilation during the first injection, and can be exhausted on a two-unit basis until the needle fluid is discharged. If it is not exhausted, it will affect the injection dose and eventually the blood sugar level.
6.Insulin storage: The enabled insulin can be stored at room temperature (≤ 25 degrees) for 4 weeks, and stored in the refrigerator of an unopened insulin refrigerator at a temperature of 2~8 degrees, do not freeze.
7. If you find that your blood sugar is not well controlled, you should check whether the insulin refill is installed correctly and whether the insulin dose is injected accurately. If you can't solve the problem on your own, you should go to the specialist clinic for consultation as soon as possible.
Precautionary measures：
1.Systemic adverse reactions: hypoglycemia, weight gain, edema, refractive error, allergic reactions.
2. Hypoglycemia: Hypoglycemia is the most common adverse effect of insulin. Hypoglycemia can occur because of too much insulin, not eating on time or too little after insulin injections, and being too active or prolonged. Once hypoglycemia such as palpitations, hand tremors, tremors, and sweating appear, eat carbohydrates (chocolate, sugary drinks, bananas, etc.) that are higher in blood sugar as soon as possible.
3. Weight gain: Long-term use of insulin can cause varying degrees of weight gain due to its effect on promoting protein and fat synthesis.
4. Edema: Some patients may develop edema after taking insulin, which is more common in the face and limbs, and often disappears spontaneously after a period of continued use.
5. Refractive error: patients initially taking insulin often have refractive error, which is characterized by blurred vision and farsightedness; When glycemic control stabilizes, symptoms disappear quickly and often do not require treatment.
6. Allergic reactions: A very small number of patients can develop urticaria, angioedema, purpura, etc. after taking insulin, and some may even have anaphylactic shock, so desensitization treatment or change the type of insulin are recommended.
7. Local adverse reactions: subcutaneous adipose tissue hyperplasia, pain at the injection site, bleeding, and bruising.
8. Induration and subcutaneous fat hyperplasia: The most common complications of insulin injections are prevented, starting with standardized insulin injections, rotating injection sites each time, and not reusing needles.
9. Pain at the injection site: Wait for alcohol sterilization to dry completely before injecting, choose a thinner and shorter needle for injection, avoid reusing the needle, and take one needle at a time.
10. Bleeding and bruising: Standardize the injection and pinch the skin correctly.
