Venous indwelling needle is a commonly used puncture technique in clinic. During the use of indwelling needle, the occurrence of phlebitis accounts for a large proportion. How to effectively reduce the occurrence of phlebitis
1. Choose a suitable indwelling needle: It is very important to choose a suitable indwelling needle. Generally, patients use 20G to 24G indwelling needles. Neonatal and elderly patients choose to use 24G to 26G indwelling needles. Indwelling needles larger than 20G will cause great damage to blood vessels, and the possibility of phlebitis is also high. Choosing the appropriate indwelling needle will prevent puncture injury. to a minimum.
2. Choose an appropriate injection site: Avoid limb joints, palpable painful areas, infected areas, damaged blood vessels, and venous valves during puncture.
3. Pulse flushing: Using the pulse flushing technique, push and stop for a while to make the liquid form a small vortex in the catheter. It is best to use a pulsed flusher to reduce the risk of catheter-related infection.
4. Tension-free fixation: use sterile transparent film, tear off the substrate, use tension-free fixation, that is, hold the film without tension, and hang the film without tension, so that the central part is aligned with the puncture point for pasting, and the sheet is smoothed from the inside out. Stick the film, and finally make it stick tightly with the skin without leaving any gaps. Immobilization does not affect the observation and evaluation of the injection site and does not affect blood circulation.
Keep these eight methods in mind to effectively prevent phlebitis caused by indwelling needles!
5. Pay attention to the use of special drugs: When using irritating and viscous drugs, pay attention to the dripping speed and use NS to flush the tube before and after, and finally seal the tube with heparin.
6. Pull out the needle in time if the puncture site is abnormal: during the use of the indwelling needle, the patient complains of pain, observes the change of skin color, skin temperature, skin edema, and induration when the needle is pulled out in time.
7. Strengthen training: Provide regular training on relevant knowledge to new nurses and young nurses. Make them proficient in the technique of indwelling needle puncture, the method of flushing and sealing the tube, and effective observation, so that they can find out the problems in the use process in time and effectively prevent them.
8. Health education: Strengthen the education of patients during the infusion process, and teach patients how to observe. Once the injection site is abnormal, notify the nurse in time so that measures can be taken in time.
