The blood return from venipuncture is good, but why is there a bulge?

Infusion is a very common method of treating diseases. Colds, fevers, or people who have just recovered from a serious illness and need to replenish energy can all be treated and conditioned through infusion. However, sometimes special situations may occur during infusion. The blood return from venous puncture is good but a bulge may appear. This is a very common situation and requires a detailed understanding of the needs and then adjustments. The following will introduce why the blood return from venous puncture is good but a bulge may appear.

Under normal circumstances, the adjustment switch during the infusion process will not cause a blister to form at the puncture site. If a blister forms locally, even if the blood return is good, it still means that the blood vessels at the needle site are ruptured and bleeding is occurring. Suggestions: According to your situation, it is recommended that the nurse remove the needle in time and re-puncture.

Several methods for dealing with difficult-to-puncture veins are introduced below. 1. Failure to expose veins 1. The veins of patients with edema are often not obvious. According to the anatomical position of the vein, local pressure should be applied with fingers to temporarily disperse subcutaneous water. It is better to expose the vein before puncture. 2. The veins of obese patients are deeper and less obvious, but they are relatively fixed and do not slide. After feeling them accurately, insert the needle at a 30° angle. After blood returns, lift the needle slightly and insert it into the blood vessel to successfully complete the procedure.
