01 Sterilization cannot be compromised! 

“Case 1

moncler jackets outlet store Zhang went to the outpatient clinic to consult the doctor, recently his blood sugar compared to the usual, some fluctuations, do not know what is going on. After detailed questioning, the doctor found that Mr. Zhang was using povidone-iodine to disinfect his blood sugar. He said that he ran out of alcohol at home and happened to have a bottle of povidone-iodine, thinking that they were both disinfectants, so they should be more or less the same.

“Tips 1.0

Insulin needs to be sterilized before injection, but iodine pov should not be used when sterilizing because insulin is a fine protein, and sterilizing it with iodine pov or iodine-containing disinfectant will affect the activity of insulin, which in turn will affect the absorption of insulin by the body.

It is recommended to sterilize the skin with alcohol before injecting insulin because 75% alcohol is colorless and dries faster, so it is best to use 75% alcohol to sterilize the skin.

02 Remove needles after use

“Case 2

Grandma Wu went to the hospital to buy an insulin pen and the doctor asked her what insulin pen she had used before. Grandma Wu took out the insulin pen she was carrying and showed it to the doctor. The doctor opens it and realizes that the needle is still on it. The doctor asked Grandma Wu why she didn't remove the needle.

Grandma Wu said it was too much trouble to install it every time, so it was convenient to keep it and take it out of the house.

“Tips 2.0

Insulin pen and needle are connected together, if it is cold, or when you put the insulin in the refrigerator, the insulin will shrink when it is cold, and the air will enter the cartridge through the needle, which will change the concentration of the insulin, the air bubbles in the cartridge will affect the dose of insulin, and the time of the insulin injection will also be affected. If it's at a higher temperature, the insulin expands and spills outside the cartridge, and also insulin can spill out if it's shaken. Either way, it affects the accuracy of the insulin dose, so it's best if the insulin isn't connected to the needle.

03 Be a little storage genius

“Case 3

Auntie Zhang went to the hospital because of dizziness and numbness in her limbs, and her blood glucose was measured to be as high as 15.4 mmol/L. When she saw the result, she did not believe it because she had been using insulin as prescribed by her doctor, and her diet was usually under good control. The doctor asked her to bring her insulin pen to see what the problem was.

When the doctor touched it, the insulin pen was still cold. The doctor asked her what was wrong with her insulin pen and told her to put it in the refrigerator and put it close to the inner wall of the refrigerator to see if the insulin had gone bad.

“Tips 3.0

Insulin should be stored in a cool place away from direct sunlight, preferably in the freezer, at a temperature of 2 to 8°C. Unopened insulin can be stored for up to two years at this ambient temperature. However, try not to hold the insulin against the inside of the refrigerator, as this may cause the insulin protein to denature and become ineffective. Insulin that has frozen cannot be thawed and reused.

It is not necessary to return opened insulin to the refrigerator. It can be stored safely at room temperature (around 25 ℃) for 4 to 6 weeks, but it is best not to use it for more than 4 weeks after opening.

04 Injections should be timed appropriately

“Case 4

At noon, Zhang was suddenly dizzy, pale and sweating, and his blood glucose was measured at 2.6 mmol/L. It turned out that Zhang had been very nervous since he was diagnosed with diabetes and had been injecting insulin as soon as he realized that his blood glucose was slightly elevated.

At noon today, his blood glucose was a bit high, so he raised the insulin dose without authorization, but the meal was served late, resulting in a hypoglycemic reaction.

“Tips 4.0

Different insulin works at different times, so the injection time is also different. Generally, insulin exerts its hypoglycemic effect 30 minutes after injection, so it is necessary to inject insulin 15 to 30 minutes before meals to ensure that it works at the right time.

To prevent hypoglycemia, make sure to prepare food before injecting insulin. Try not to move after the injection to avoid hypoglycemic reaction. Patients should eat regularly and quantitatively, and should not add or subtract food at will, so as not to affect the effect of lowering glucose.

05 Stay at least 15s under the skin

“Case 5

Luo Da Niang was hospitalized because of elevated blood sugar. When she was hospitalized, the nurse came to give her insulin injection. Mrs. Luo asked the nurse why her blood glucose fluctuated so much when she was in the hospital but not when she returned home.

The nurse asked Mrs. Luo to do it on the spot and realized that she had pulled out the insulin immediately after injecting it and did not let the insulin stay in sufficiently.

“Tips 5.0

Under normal circumstances, pulling out the needle will bring out a small amount of insulin, and if the residence time is insufficient, the needle will bring out a large drop of insulin, which not only causes a waste of insulin, but also affects the effect of lowering sugar.

Therefore, after the injection, do not pull out the needle immediately, but let the needle stay under the skin for more than 15s, so that the drug can fully enter the body.

The correct use of insulin pens may seem trivial, but a small detail may lead to blood sugar fluctuations, so it is important for sugar users to master the correct method of insulin injection and related knowledge to stabilize blood sugar and delay the development of complications.
