How to prevent intravenous phlebitis?

In modern medical technology, various treatment methods have brought better protection to people's health. However, some technologies are imperfect and may have adverse effects on people's health. For example, phlebitis is an inflammation caused by an intravenous needle, which can cause great harm to the patient's health. Therefore, medical workers should strengthen their technical training, improve their personal technical level, and actively prevent the occurrence of intravenous phlebitis during daily treatment. This is also the purpose of protecting the patient's health from the adverse effects of medical technology. Let's take a look at how to prevent intravenous phlebitis.

1. Pay attention to aseptic operation. This is the top priority of nursing operations.

2. Avoid joints. The joints move frequently, and indwelling needles can easily cause mechanical stimulation and damage to the vascular endothelium.

3. Try to minimize the placement of indwelling needles in the lower limbs. Medical Education Network collected and sorted out that the lower limbs have more venous valves and the blood flow is congested, which can easily cause drug retention and blood embolism. If necessary, the lower limbs can be raised 20 to 30 degrees to speed up blood return and reduce the stimulation of drugs on the lower limbs.

4. Correct puncture method. The high success rate of puncture can effectively reduce damage to the skin and blood vessel walls around the puncture point.

5. Avoid chemical stimulation. When infusing high-concentration, large-molecule drugs, the drip rate should be slowed down and sufficient dilution should be given. For patients receiving intravenous transfusion, it is recommended to establish a separate intravenous access and not use an indwelling needle. The disinfectant should not be too concentrated to reduce the risk of chemicals penetrating through the skin into the blood vessels and causing irritation.

6. Replacement of the indwelling needle. When the nurse finds clinical indications at the patient's puncture site (such as slowed drip rate or no drip, exudation, redness and tenderness around the puncture site, the patient complains of obvious discomfort at the puncture site, etc.), the indwelling needle is replaced.

7. Try to choose a smaller indwelling needle. Studies have shown that the ratio of the diameter of the indwelling needle to the diameter of the blood vessel is related to the occurrence of phlebitis. Therefore, choosing a smaller needle can reduce the physical stimulation to the blood vessels caused by the indwelling needle.

8. Observe the condition of the film. When the nurse checks the condition of the indwelling needle at the handover of each shift, he should pay attention to whether the film is contaminated, damp, or falling off. If so, it should be replaced in time.
