The full name of PVL is Peripheral Venous Line, which means "peripheral venous catheter". It is a medical device in which a catheter is inserted into a blood vessel in the vein to deliver medications or fluids. Here are three paragraphs about PVLs.
PVLs are used in a wide range of medical scenarios, including infusion, rehydration, and intravenous (IV) injections, etc. Insertion of a PVL requires training and guidance from a medical professional, as well as hygienic and safe handling. Proper sterilization and anesthesia are required before inserting the catheter. Insertion requires finding a suitable vein and inserting the catheter into the vein by puncture cannulation.
Although the PVL is a very common medical device, there are some things that need to be taken care of during its use. First, the patient's basic information needs to be evaluated before insertion of the catheter, including knowledge of the patient's medical history, family history, and history of allergies. Secondly, when inserting the catheter, it is necessary to find a suitable vein, and during the insertion process, it is necessary to pay attention to the possible complications, such as infection, bleeding, and so on. Finally, the patency and position of the catheter need to be checked frequently when using PVL, so that problems can be detected in time and measures can be taken to avoid unnecessary risks.
For patients who have been fitted with a PVL catheter, certain management and care is required. The catheter needs to be removed in a timely manner after its use is completed, and rest and nutritional adjustments need to be taken care of. Patients need to maintain rest and avoid situations such as exercise and agitation, so as not to affect the patency of the venous catheter. The injection site around the catheter needs to be checked frequently for infection in use and dealt with in time. At the same time, patients need to be psychologically cared for, so that they can use the PVL with confidence and reduce unnecessary fear and pressure.
