1. The selection of bandages should achieve a good fixation effect. It is very important to choose the elastic bandage and dressing correctly. When selecting, the length of the elastic bandage should be selected according to the upper example of the limb of the venous catheter, and the elastic bandage should be tight and fit. It can effectively fix the venous catheter without hindering the blood circulation of the arm. Our department currently uses elastic bandages with a width of 7cm and a length of 15-20cm.

2. How to use: Place the cut self-adhesive elastic bandage directly above the transparent digital sticker from the end with the first circle slightly looser, the second circle slightly tighter, and wrap around the dry lower arm. The other end of the elastic bandage will be sticky. It should be fixed on the hand well. It is worth noting that the heparin cap needs to be put in the elastic mesh bandage. During the infusion treatment, the elastic mesh bandage should be folded upward about 5cm to expose the heparin cap to avoid contamination. .

3. After observing the patients with adverse reactions, the main problems are summarized as follows.

The most common complication is phlebitis, which manifests as local pain, redness and swelling, and cord-like changes in veins. The cause is mechanical damage in the early stage of catheterization, chemical stimulation and special physique in the later stage. The effective fixation of elastic bandages can reduce the occurrence of mechanical veins. Inflammation occurs because the traditional fixation method is pure transparent film fixation, which is affected by some subjective and objective factors, such as dampness of the film, patient bathing, sweating, falling asleep, physical activity, irritability, undressing, etc., it is inevitable that the catheter will be pulled out Or the risk of spontaneous prolapse, mechanical stimulation has increased the occurrence of phlebitis. Once the catheter is removed or prolapsed, the catheter must be re-inserted. This not only affects the treatment, but also increases the patient's pain and economic burden.

Effective fixation of elastic bandages also requires proper length, width, and tightness of elastic bandages. Too tight will affect the patient's blood circulation and induce thrombophlebitis, while too loose will not have a fixation effect. After the patient has symptoms of mechanical phlebitis, the patient can be lifted up, the limbs are relaxed, and the upper arm can be relieved after a few damp and heat. Secondly, it is manifested as bleeding at the puncture site. After the venous catheter is fixed with elastic bandage, the chance of bleeding is reduced.

The elasticity of the elastic bandage strengthens the tension of the soft tissue on the surface of the hematoma cyst, causes the inner and outer walls to adhere and wither, eliminates the cyst cavity and heals. The surrounding soft tissues naturally retract under the influence of elasticity, and resume normal functions gradually. On the first day of intubation, the elastic bandage requires a large amount of pressure to prevent bleeding. On the second day, the pressure should be appropriately reduced. In order to avoid color ringing of blood circulation, 4 patients in this group were re-wrapped with elastic bandages after bleeding occurred, and the symptoms of local ice were relieved.

A small number of people will experience weakness in puncturing the affected limb. The main reason is that the elastic strap is too tight. Adjust the tightness of the bandage in time, and the patient’s symptoms disappeared quickly. After 24 hours of intubation, a full-time nurse removes the bandage and maintains the venous catheter, and decides whether to continue using the elastic bandage according to the puncture point.

The elastic bandage is convenient to obtain materials, fixed by adhesive, simple operation, easy to grasp, beautiful in appearance, can be cut at will, reduces waste, has good practical value, and is well received by patients.
