How much do you know about the causes of phlebitis? In clinical practice, phlebitis is divided into thrombotic deep vein phlebitis and thrombotic superficial vein phlebitis. Thrombotic superficial vein phlebitis is further divided into two types: thrombotic superficial vein phlebitis and migratory thrombotic superficial vein phlebitis. Phlebitis not only causes serious harm to patients but also imposes a heavy burden on their families and society. So, how much do you know about the causes of phlebitis? Regarding this issue, we will now invite experts from Shanxi Yikang Peripheral Vascular Hospital to provide us with a detailed introduction.
The causes of phlebitis include:
1. The material, length, and diameter size of the catheter needle can cause phlebitis.
2. Poor operational techniques are a cause of phlebitis.
3. Inappropriate puncture sites.
4. Leaving the catheter needle in place for too long.
5. Improper fixation methods can lead to phlebitis.
6. The acidity or alkalinity of the intravenous fluid being too strong, or incompatibility causing precipitation.
7. The patient's own pathological and physiological condition, such as age or disease causing fragile blood vessel walls leading to inflammation.
Groups of people who are prone to phlebitis:
(1) People with slow blood flow – Long-term bedridden individuals, those with heart failure, tumors pressing on veins, varicose veins, and venous malformations, pregnant women all have slower blood flow. Platelets adhere to the vascular wall, easily forming clots that lead to thrombophlebitis.
(2) People with increased blood coagulability – Patients with coronary heart disease, hypertension, and diabetes have increased platelet counts or clotting factors, reduced fibrinolytic activity, and increased blood coagulability leading to clot formation. Other conditions such as dehydration or blood loss due to various reasons can also cause blood concentration and increased coagulability. An increase in platelet count and viscosity, as well as increased levels of fibrinogen, prothrombin, and other clotting factors, can cause blood concentration. If there are malignant tumors in the pancreas or lungs, they can release large amounts of tissue factors into the blood, activating the clotting system and increasing blood coagulability, leading to thrombophlebitis.
(3) People with damaged vascular endothelium – Some patients receiving sclerosing agents, hypertonic solutions, antitumor drugs, contrast agents, 24-hour intravenous catheters, tumor cell invasion, or bacterial infections may experience vascular endothelial damage. After the inner membrane is damaged, it becomes rough and uneven, making it easier for platelets to aggregate, thus causing blood clotting and promoting thrombus formation.
(4) People with rheumatic diseases – Rheumatism invading the vascular wall can cause vasculitis, which leads to thrombus formation on this basis. This type of thrombotic phlebitis often presents as migratory and is more difficult to treat.
The above is a detailed explanation by experts regarding the causes of phlebitis. We hope it helps you. If you have more questions, you can consult online with experts from Shanxi Yikang Peripheral Vascular Hospital. Finally, we wish you good health.
