What is a vascular catheter?

Vascular catheter or venous catheter is a thin flexible plastic tube that is inserted into the patient's vein and remains there for repeated access to the vein. The catheter allows easy access to the bloodstream to the patient for medical use, such as periodic blood collection and intravenous (IV) drug administration. While a simple tube associated with a needle can be sufficient for short -term use, patients with long -term vascular approach requirements can benefit from a vascular catheter that could be implanted during surgery on a vascular approach. The tube usually moves through the vascular system until the large veins reach the middle of the chest. Central catheters can generally be used to monitor heart function and also supply drugs or nutrients to the bloodstream.

Doctors use vasculum catheters AR for various reasons, including anti -cancer drugs or chemotherapeutic drugs for cancer patients. Patients with severe bacterial infection may dosTitter intravenous antibiotics through a venous catheter. People with kidney disease usually receive periodic hemodialysis of treatment to remove waste from blood, which can be provided through the vascular catheter. Some patients receive blood transfusions through a venous catheter to replace the lost blood or to supply healthy blood cells into the bloodstream.

For many patients, the vascular catheter has several advantages, including a repeated approach to the patient's vascular system without painful needle and advertising every time a vascular approach is needed. Medium catheters may be less likely to cause leakage at the point where the needle enters the skin than the normal IV. Patients with a central catheter have minimal scarring from the input of the needle compared to patients who can withstand a separate needle each time the vascular system needs to be approached.

BravEating or bleeding at the point of insertion of the catheter, catheter infection and damage to the blood vessels are possible risks of using the vascular catheter. The catheter can be released if it is not carefully monitored. Air in the catheter can cause chest pain. In rare cases, they also caused the irregularities of the heart rhythm.

The nurse usually gives the patient instructions on maintaining a clean vascular catheter, which is ready for further use. Patients usually need to reduce physical activity in the area where the catheter enters the body such as the arm. An individual with a vascular catheter may have to sleep in a different position than it is used to prevent damage to the catheter.
