Injected insulin 3 major considerations

Reasonable choice of injection site
The commonly used injection site is the abdomen (an area 5 cm away from the umbilicus), the outside of the double upper arm, the buttocks, and the outside of the thigh. Absorption of insulin in different parts from fast to slow, followed by abdomen, upper arm, thigh, buttocks. If the occasional meal time is advanced, abdomen injection is selected; if delayed, hip injection is selected. In addition, local exercise can speed up absorption. If you want to participate in exercise, you should avoid injection on the upper arm and thigh, so as to avoid the absorption of insulin due to physical exercise, resulting in hypoglycemia after exercise. In addition, the injection site should be changed frequently and the two injection sites should be spaced more than 2 cm apart. It is not recommended to repeatedly inject at the same site to minimize tissue damage, swelling, and atrophy of subcutaneous fat.
Mastering methods can reduce injection pain
Insulin temperature should not be too low. Insulin has just been taken out of the refrigerator. Since the temperature is low, it can cause pain when injected. Therefore, insulin should be injected for a while before injection and alcohol should be injected after volatilization. The alcohol used for skin disinfection is not injected. The alcohol is brought from the eye to the skin and causes pain. The skin of the injection site is gently squeezed by hand, and mild pain is caused before the injection. This not only facilitates injection, but also distracts the pain caused by needle sticking; the needle is faster when injected. Need to be decisively fast when entering the needle, the slower the needle, the stronger the pain. The muscles at the injection site should be relaxed; replace the needles regularly. The needle of the insulin pen is very thin. After repeated use, the needle may become blunt or undercut, causing injection pain.
Insulin storage method
Insulin is a kind of protein hormone. If the temperature is too high or too low, it will easily cause denaturation and failure. Avoid freezing or sun exposure. The optimal storage temperature for insulin is 2°C to 8°C. Unopened insulin can be stored for 2 to 3 years in this environment. Therefore, unopened insulin is best kept in a refrigerator. Insulin can be stored for 4 to 6 weeks at room temperature (about 20°C), and beyond this limit, there will be a slight decrease in efficacy. When placed at room temperature, insulin should be placed in a cool, dry place.
Tip: If insulin is in the refrigerator, the temperature is relatively low, immediately after taking out the injection, it will make the patient very painful. It can be stored in the refrigerator at room temperature and can be stored in the unsealed environment for two years. However, the shelf life must be clearly seen when using it. If it exceeds the efficacy, it will fall and it will not be easy to inject.
