**Uncovering the Causes of Various Types of Phlebitis**
With the continuous improvement of daily life, the number of people suffering from phlebitis is increasing. In particular, thrombophlebitis caused by intravenous infusions has become very common in clinical settings. So, what are the causes of phlebitis? To address this question, we will invite experts from Shanxi Yikang Peripheral Vascular Hospital to provide a detailed introduction to the causes of phlebitis.
**Causes of Phlebitis:**
1. **Chemical Drug Irritation:** This can occur when various irritant solutions or hypertonic solutions are injected into veins, such as hypertonic glucose solution, various antibiotics, alkylating agents, and organic iodine solutions.
2. **Catheter-Induced Continuous Infusion:** This can directly damage the venous wall or cause injury due to mechanical impacts, leading to an inflammatory response.
3. **Varicose Veins in the Lower Limbs:** Due to blood stasis in the veins, nutritional changes occur, and chronic infections can lead to oxygen deprivation and inflammatory damage in varicose veins, causing phlebitis.
**Phlebitis Caused by Infusion:**
1. **Improper Fixation Methods:** If the puncture site is not properly secured, it may cause the needle to slide, which is one of the causes of phlebitis.
2. **Inappropriate Catheter Size:** Using a catheter with a diameter that is too large can stimulate the vessel walls.
3. **Puncture Near Joints:** If the puncture site is too close to a joint, movement of the joint can cause constant friction between the needle and the vessel wall, leading to an inflammatory reaction.
**Chemical Phlebitis:**
This type of phlebitis is often caused by insufficient drug dilution, excessively high acidity or alkalinity of the infusion, overly concentrated solutes, or differences in the material of the indwelling needle.
**Bacterial Phlebitis:**
This is usually associated with improper sterilization methods, poor puncture techniques, disruption of the sterility of the infusion set, or leaving the catheter in place for too long.
