Introduction to Dialysis catheter

In this article, we have gathered some information on the Internet about dialysis catheters. We hope you will find it useful. Our company was established by medical experts and senior executives to be the most professional and high-end medical product testing organization in China. We offer tunnel hemodialysis catheters, temporary hemodialysis catheters, permanent hemodialysis catheters, contact isolation infusion sets, tandem diabetic infusion sets, etc. The author is not a professional, please contact us if you have any questions, we have professional staff to provide services for you.

This passage is going to talk about the followings of the dialysis catheter:

1) Insert dialysis catheter

2) Remove dialysis catheter

3) Precautions for the usual use of dialysis catheter

1) Insert dialysis catheter

The dialysis catheter is chosen according to the patient's vascular condition. For temporary lines, femoral and jugular venous catheters are used, or the superficial arteriovenous system of the arm is used for dialysis. For peritoneal dialysis, the location of the abdomen is usually chosen. The dialysis catheter is handled by a physician under aseptic technique and should be left in the hands of a professional physician with confidence.

We provide infusion sets, hemodialysis catheters (packaged live tandem infusion sets, subcutaneous stealers), contact high fluid, temporary hemodialysis catheters, permanent hemodialysis catheters, etc. You can rest assured to choose us, if you have any needs can contact us.

Different dialysis catheters are used for different conditions. Uremic dialysis is generally available for cannulation in the internal jugular vein, femoral vein, external jugular vein and so on, generally the jugular area is the majority, which is not easy to block the tube. To do hemodialysis treatment, it is necessary to establish a vascular access, both to draw blood out of the body and to be able to recycle it into the body after extracorporeal purification. Otherwise, once dialysis treatment is required and no arteriovenous endovascular fistula is available a temporary central venous cannulation is required. The general sites available for cannulation are internal jugular vein, femoral vein, and external jugular vein. Because central venous cannulation is associated with a number of complications such as infection, formation of venous thrombosis, and resulting venous stenosis, it is recommended that arteriovenous endovascular fistulas be preferred for vascular access. Since the maturation period of arteriovenous endovascular fistula is 1 to 3 months, the procedure needs to be performed earlier.

2) Remove dialysis catheter

When dialysis catheter is removed, the catheter should be routinely disinfected, and 10 mL-20 mL of saline should be injected with a sterile syringe to flush out the blood in the tube, and 20 mg/mL of heparin saline should be injected in strict accordance with the amount of anticoagulant solution required by the catheter, with positive pressure in the syringe at the end of the push, and the other hand should be quickly clamped with the arteriovenous line clamp at the same time to prevent the reflux of blood in the lumen. The other hand is also used to quickly clamp the arterial line clamp to prevent blood backflow in the lumen.  The amount of heparin must be increased in hypercoagulable patients, and even the tubing must be sealed with heparin stock solution to ensure the line is open. The double-lumen catheter should also be flushed with saline under pressure after the sealant is withdrawn before the start of dialysis. The catheter is not normally used for other purposes than emergency, such as blood draws and infusions.

3) Precautions for the usual use of dialysis catheter

Dialysis patients require daily routine disinfection of the skin around the dialysis catheter, changing sterile dressings, careful observation of the catheter outlet and surrounding skin, if redness, swelling, heat or purulent secretions overflow, should be given local strengthening of drug changes to keep the skin dry, but also a small amount of application of mupirocin ointment or erythromycin ointment, blood specimen culture, and timely selection of broad-spectrum antibiotics, while sealing the tube with additional antibiotics, wait for the culture results and then make the appropriate antibiotic adjustment, 2 weeks of treatment is not effective, consider pulling the dialysis catheter.
