What is a central venous catheter?
The central venous catheter is a thin, long flexible tube that can be inserted into a large vein in the chest, weakness or neck. It can be used to administer drugs, nutrients and fluids. Management can take place for a longer period of time. Blood can also be pumped from this type of catheter. One advantage may be that these catheters are longer and are generally placed in larger veins, allowing more liquid distribution. In addition, they can remain in the body for a longer period of time. The periods of time may be extended to several weeks or more. Some of these reasons include administration of drugs such as chemotherapy, receiving dialysis and for long -term parenteral nutrition or pain treatment. Other reasons may include frequent blood collection, quickly take medicines that affect long -term antibiotics, and for any other reason that may be a frequent intravenous approach. Local anesthetics are generally applied to the skin before insertion. Some of the different types of central venous catheter include a peripherally inserted centerEal catheter (PICC), tunnel catheter and implanted port. Different catheters usually have different insertion locations.
PICC lines are normally inserted into the vein into the arm rather than in the chest, neck or groin. The tunneled central venous catheter is generally inserted surgically. Can be inserted into a vein into the chest or neck. The drug can be administered at one end that is a tunnel through the skin. This could help better keep the catheter in place.
Implants of ports are generally left under the skin. Medicines can be served through the skin into the catheter. There are some implanted ports that can be complemented by a small tank. This type of catheter can usually be easier to maintain daily. It usually requires minimal daily care and may be less obvious than a tunnel catheter or PICC line.
The catheter insertion site can be found using ultrasound or X -ray. If the catheter is placed in the chest, the subc may be insertedLavian vein. Inserting into the neck can be placed in the inner jugular vein. In addition, catheters can be placed through the weakness through a femoral vein.
Complications may arise from the location of the central venous catheter. One of the most common problems may be infections. If the infection is suspected, the blood may be taken from the catheter and vein other than the place of insertion. Antibiotics are generally used to treat infections. IEV, if necessary, the catheter can be removed.
Other possible problems may include pneumothorax, which is a collapsed lung. Further complications may occur when the catheter shifts. If the catheter moves from the site, it may be necessary to move. Bleeding from the place of insertion can be further complications.
The symptoms of the problem may be similar to different types of catheters. Other problematic symptoms may include fever, pain, redness or tenderness at the place of insertion, among other things. If a suspicious problem with an infection or other catheter problem should be a doctor aboutBVykly called immediately.
