Self-monitoring is one of the “five horses” in the comprehensive treatment of diabetes mellitus, and it is necessary for sugar lovers to carry out self-monitoring in order to better achieve the blood glucose standard and prevent various acute and chronic complications. The significance of self-monitoring is to obtain blood glucose and related information, and use it as the basis for adjusting medication, diet and activity, so as to improve the overall effective control of the disease and the ability to regulate the quality of life. Therefore, self-monitoring is an important part of diabetes management, and it runs through the whole process of diabetes treatment and efficacy evaluation. However, sugar lovers, have you really mastered the correct method of monitoring finger blood glucose? Dip a 75% medical alcohol or 75% medical alcohol cotton ball, center it on the point where you want to tie the needle to collect blood, rotate and disinfect, and wait for it to dry before measuring blood glucose. It is not recommended to use iodophor swabs or cotton balls for disinfection, as the iodine in iodophor and iodine can react with the enzymes in the blood glucose test paper, thus affecting the accuracy of the blood glucose value. The selection of blood collection site Measuring capillary blood glucose at the end of the finger should be preferred to the ring finger, middle finger or both sides of the end of the index finger, and it is not recommended to use the abdomen of the finger, because the abdomen of the finger has more fat pads and more sensory nerve distribution, and the amount of blood collected is less and the pain is greater. When collecting blood, the palm of the hand is down, the blood collection finger is underneath, and the rest of the fingers are upturned, and the puncture point should be at the lowest point of the finger, so that enough blood can be collected. Sugar lovers who monitor blood glucose for a long time can take turns to collect blood in different parts of different fingers, which can protect the fingers. Choose the appropriate monitoring time and frequency At the beginning of insulin therapy, self-monitoring blood glucose at least 4 times a day, and after reaching the treatment goal, it can be 2~4 times a day; when the blood glucose control is poor or critical, monitor blood glucose 4~7 times a day until the condition is stable, and when the blood glucose control goal is reached, it can be monitored 1~2 days a week. Sugar lovers choose 2 days a week to measure fasting, after 3 meals and before bedtime. Reasonable storage of test strips Blood glucose test strips should be placed in a dry environment at 10℃~30℃ and protected from light. Remember not to place them in the bathroom, kitchen, refrigerator and other places that are susceptible to moisture or direct sunlight; avoid touching the test area and blood drip area of the test strips as much as possible when taking out the test strips; pay attention to the expiration date of the test strips, which is generally 3 months after opening the bottle; if possible, try to purchase individually packaged blood glucose test strips. Keep the test strips in eight words: dry, cool, protected from light and sealed.
