Dialysis Catheters: To Surge In The Near Future
Dialysis catheters are special tunnel-type catheters as they are placed under the skin. These catheters are usually of two types that include cuffed and non-cuffed. Non-cuffed tunneled catheters are generally used for emergencies and for short periods. These catheters are artificial indwelling transcutaneous conduits that are used for accessing the intravascular space during renal replacement therapy.
Dialysis Catheter is also known as tunneled catheter and is placed under the skin. The catheter has double tubes with separate openings. There are two types of opening for the dialysis catheter namely as red and blue. The red opening is the arterial that draws blood from your vein whereas the blue opening of the catheter allows clean blood to return to the body. It is essential to take care of the catheter so that it lasts longer and prevent problems

The catheters are used in the medical condition of hemodialysis that occurs due to the failure of kidneys and thus losing the ability to remove the additional fluidic content from the body and clean the blood. Dialysis catheters provide an alternative to gain an access to reach the blood to perform hemodialysis. It is imperative that the catheter dressings are clean and dry before the procedure. Simultaneously, the region where the hemodialysis catheters are inserted is also sterilized and the process is carried out with air not allowed to enter the device. The haemodialysis catheters are placed in the central arteries of the patients whose condition do not support the usage of AV fistulae. The preferred site for this procedure is internal jugular vein but it is advisable to look for another catheter site as well that ensures sufficient blood flow for dialysis.
Dialysis catheters are divided into two categories, one preferred for extracorporeal modes of renal replacement therapy that include haemodialysis and the second one for peritoneal dialysis. The catheters of the first category bore central venous lines to extract blood from the patient and ultimately return to their body. On the other hand, catheters used in peritoneal dialysis allows the fluid or dialysate to enter the intraperitoneal space to get in contact with the membrane.
Vascular access for the hemodialysis process is gained through an arteriovenous (AV) fistula, arteriovenous (AV) graft, or dialysis catheter (TDC). AV fistulas and AV grafts are designed for long-term use, while dialysis catheters are designed for short-time use. There exist two types of dialysis catheters: tunneled and non-tunneled dialysis catheters. Non-tunneled catheters may be cuffed or non-cuffed. Hemodialysis catheter is a soft tube inserted into a vein either in the neck, chest, or leg (close to groin). It is divided into two after the tube exits the body. Vascular access is of importance to the treatment. It is likely to be vulnerable to infections and clotting of blood, which are generally the leading cause of catheter dysfunction. A majority of hemodialysis catheters are inserted and fixed onto the anterior chest wall when the patient holds a supine position.
