With the improvement of hygiene concepts, many friends' homes will prepare some basic medical supplies for emergency use. In the concept of ordinary friends, cotton swabs are used for disinfection. Of course, some friends use it to remove ears, make-up, etc. However, what many friends don’t know is that cotton swabs will be counterproductive if they are not used correctly. Effective. Now I will use my own experience to teach you how to use cotton swabs correctly.
1. Let me talk about the most basic use of cotton swabs: disinfection. Let's take disinfection of the skin as an example. We center on the part that needs to be disinfected, and rotate it in one direction in front of it for disinfection, with a diameter of more than 5 cm. A cotton swab can only be used once and cannot be recycled to avoid cross-infection. There is another common function in front of you: pressing the wound. There are two ways to press: First, press normally to stop bleeding. Take subcutaneous injections (vaccinations) and intramuscular injections (buttock injections) as examples, just press the cotton swab parallel to the wound.
2. Press longitudinally. Taking intravenous injection (mainly for blood tests) as an example, the general nurse's needle insertion technique is to pierce the subcutaneously from above or from the side of the vein, and then sneak into the vein along the direction of the vein. So generally after the needle is removed from this kind of wound, it looks like one wound from the surface of the skin, but you are actually two wounds. If the pressing technique is not correct, the skin around the needle inlet will appear bluish-purple color. In fact, this is caused by congestion in the wound in your skin. Don’t worry if you encounter this situation. The congestion will usually disperse on its own in about a week. At this time, your front should be pressed longitudinally along the vein. The time the swab was pressed. The pressing time of the cotton swab after needle removal is also very particular. Generally, people who are under the age of 40 and have good coagulation function and have not taken anticoagulants can usually take about five minutes. People who are over forty years old or who have taken anticoagulants should press for about ten minutes or longer, depending on individual circumstances.
The contraindication of swab pressing. The most taboo thing about pressing the cotton swab after removing the needle is to press it for two minutes and take it up to see if it bleeds. Under normal circumstances, as long as you press for less than five minutes, the wound will bleed. And the act of picking up the cotton swab from time to time will only cause the blood around your skin to become a bluish purple.
