What should diabetic patients pay attention to when injecting insulin?
What should diabetic patients pay attention to when injecting insulin? Diabetic patients should be familiar with insulin injections, and they should do it at home by themselves, but can you really inject insulin? Do you know which part of the body is best absorbed by injection?
If the method is not correct, it will affect the absorption of insulin, which will lead to the loss of blood sugar control. Everyone should know the horror of loss of blood sugar control!
So today I will teach you the correct way to inject insulin:
1. Wash your hands before injection.
2. If you are using suspended insulin, you need to mix it thoroughly.
You can place the insulin between the palms of your hands, roll 10 times, and then flip up and down through the elbow joint and forearm 10 times. The above actions need to be repeated many times until the insulin is transformed into a uniform cloud-like white liquid.
3. Drain the liquid and the gas in the needle before injection.
4. Use alcohol to disinfect the injection site twice, the first time with a cotton swab clockwise, and the second time counterclockwise.
The disinfection area is larger than a circle with a diameter of 5 cm. You should wait until the alcohol is completely volatilized before injection.
5. The skin should be lifted up during injection, and the needle should be quickly inserted into the needle at a 90-degree or 45-degree angle.
For relatively thin patients, when using a longer needle for injection, a 45-degree angle should be used to avoid injection into the muscle layer. The correct way to pinch the skin is to use your thumb and index finger or middle finger to pinch the epidermis and subcutaneous tissue, excluding the muscle layer. Avoid pinching together with the muscle layer. After pushing the liquid, it is best to stay for 10 to 30 seconds. Then pull out the needle to facilitate the full absorption of the liquid medicine.
1. The choice of location
The body parts suitable for insulin injection are: the abdomen, the outer thigh, the outer upper arm and the outer upper side of the arm.
Absorption speed: abdomen> upper arm> thighs, buttocks
In order to better absorb insulin, it is critical to choose the best injection site. Different parts of the body absorb insulin at different rates. Generally speaking, patients should prefer the abdomen as the injection site. Not only because the abdomen absorbs faster, but also because the subcutaneous fat in the abdomen is thicker and evenly distributed, it is not easy to inject into the muscle layer, and the abdomen absorbs insulin at an even rate and the effect is good. When injecting, avoid the circular area with the umbilicus as the center and a radius of 2.5cm, and inject insulin outside this area.
The often said injection site of the upper arm mainly refers to the outer 1/4 of the upper arm. Although the absorption rate is fast, the subcutaneous tissue is thin and easy to inject into the muscle layer.
The absorption rate of the thigh and buttocks is similar, and both are slower. When injecting into the buttocks, choose the outer part of the upper end of the buttocks. Choose the upper side of the thigh for injection, not the area near the knee. The anterior and lateral thigh injections are not suitable for thin patients.
2. The injection site should also be based on the type of blood sugar and insulin
Patients with high blood sugar should choose a site that absorbs quickly, such as the abdomen. In addition, abdominal injection is also suitable for patients with short-acting insulin and short-acting insulin.
Long-acting insulin generally has no site limitation. In order to distinguish the common site of short-acting insulin (abdomen), it can be injected into the buttocks, especially for patients who inject intermediate-acting insulin who wish to act for a longer time, they can also be injected into the buttocks.
Experts remind that human skin is composed like this: epidermis → dermis → subcutaneous tissue → muscle, and insulin needs to be injected into the subcutaneous layer. The muscle layer is rich in blood vessels. If insulin is absorbed too quickly, it is easy to cause hypoglycemia, so it is easy for arms and thighs. It is best to use an ultra-fine and ultra-short needle for injection into the muscle.
3. When will the injection site be replaced?
After a period of time after insulin injection, patients will find that they often have a big hard bump at the injection site. Don’t be afraid. This is the local induration and subcutaneous fat hyperplasia after insulin injection. It is one of the common complications of insulin therapy. Rotation of the injection site can effectively prevent this complication. Once subcutaneous fat proliferation, inflammation or infection is found at the injection site, the injection site should be replaced.
