Many patients often appear indigo because they do not have a good eye. Today we will talk about the causes and prevention methods of indocyanine after injection.
1. The pressing position is wrong when pulling the needle
When the nurse performs a venipuncture operation, the needle tip first penetrates the skin and then enters the blood vessel. Therefore, the venipuncture actually forms two pinholes on the skin and blood vessels, and there is a certain distance between the two needle eyes. If the patient presses the needle eye on the skin after the injection, the blood will infiltrate into the skin from the needle eye on the blood vessel wall, forming blood stasis, that is, the patient sees the injection at the needle.
Therefore, after the infusion is completed, the nurse should instruct the patient to press the puncture point along the direction of the blood vessel with the thumb, so that the pressing area is large, and the occurrence of indigo at the injection site can be avoided.
2. Multiple punctures in the same blood vessel
If the needle is injected at the same position multiple times for various reasons, the local blood vessel may be damaged, which may cause blood to flow out of the blood vessel and accumulate in the surrounding tissue gap. Therefore, during the puncture, the nurse should try to avoid multiple punctures in the same blood vessel.
3. Pressing the needle after pulling the needle is not enough time
The time to press the needle eye is closely related to whether subcutaneous bruising occurs, so the pressing time after the needle is taken should be 5 minutes or more. For some people with coagulation disorders, it is necessary to extend the compression time.
4. Elderly blood vessels are brittle
The blood vessels of the elderly are relatively clear, but the blood vessels are relatively brittle, and the elasticity is poor. If the needles are not pressed in time after infusion, the skin will be subcutaneous. In addition, some elderly people have cardiovascular and cerebrovascular diseases, and need to take aspirin for a long time to prevent thrombosis, but this also prolongs the clotting time. The time of pressing the needle should be prolonged to prevent bruising at the injection site.
5. Excessive pressing of the needle eye after pulling the needle
Some patients are over-stressed after the needle is removed, and the needle is pressed hard. As a result, although the blood vessels do not ooze, the surrounding normal tissue will be pressed out, so do not over press.
6. Press the needle eye after pulling the needle
During the process of pressing the needle eye, the patient should not move the cotton swab back and forth, and do not press the side of the needle eye. Repeated pressing of the needle eye can cause the blood vessels that have already coagulated to bleed again, resulting in subcutaneous bruising.
Indigo processing tips
1. Cut the potatoes into thin slices and stick them on the indigo. The potato chips are replaced after oxidation and blackening. A small potato can basically solve the problem of indigo.
2. Wet and hot compress: Dip the towel into hot water of about 60 °C, remove it, wring it out, apply it to the indigo, cover it with plastic film, every morning and evening, every time for 20 to 30 minutes.
