The catheters for hemodialysis are divided into long-term catheters and temporary catheters, which can be divided into neck catheters and leg catheters based on their location. The most common problem with hemodialysis catheters is infection, so in terms of care:
1. Do not touch the outer end of the catheter with your own hands.
2. When washing hair or taking a shower, be careful to avoid water entering the inside or outside of the catheter.
3. If the catheter is in the leg, try to reduce leg movement as much as possible to avoid catheter bending and infection. The common problem with hemodialysis catheters is the breakage of sutures to avoid excessive pulling of the catheter. Catheters may be prone to thrombosis, especially temporary catheters, which may be more prone to thrombosis. At this point, it is important to note that temporary catheters should be replaced regularly, or replaced with long-term catheters or arteriovenous fistulas. If there is poor suction in the catheter, heparin sodium can be used to seal the tube.
