09#fixing method
The fixation method of intravenous infusion is an important link in the whole infusion process. According to the principles of mechanics and aesthetics, it is more standard to adopt the side-rolling method, that is, stick the skin on one side first, and then tighten the adhesive tape to the skin on the opposite side, so that the adhesive tape can be in a tense state. , Ensure that it is not loose, and properly fixed can prevent the needle from piercing the vein, and can also prevent microorganisms from being brought into the tissue by the loose needle tip.
10#needle pulling method
When pulling out the needle, first press the belly of the finger along the vein on the small dressing covering the puncture site. The pressure range is centered on the two puncture points of the skin and the blood vessel wall, and should be larger than the two puncture points. Press immediately after the needle tip is pulled out. The puncture site takes 2 minutes to 5 minutes, and subcutaneous congestion is generally not caused. Pulling out the needle tip while pressing on the puncture site can cause local pain or cause damage to the vessel wall. Due to the different methods of holding the needle handle when pulling out the needle, it can cause different blood vessel damage, pain response and congestion around the blood vessel.
