VIThe hemodialysis catheter is one of the commonly used dialysis accesses in clinic.
Clinically, in order to provide sufficient blood flow, dialysis catheters generally need to be placed in relatively large central veins such as the internal jugular vein, femoral vein, or subclavian vein.
According to the type of dialysis catheter, it is usually divided into two types:
Temporary catheter without polyester sleeve, temporary catheter without tunnel, and tunnel semi-permanent catheter with polyester sleeve. Generally, the temporary catheter is placed for a shorter period of time and is more likely to be infected, and the general placement time does not exceed two weeks.
Indwelling dialysis catheter precautions
Prevent blood clots:
Hemodialysis catheters should be used exclusively for their own use, and should not be used for other purposes, such as intravenous infusion, venous blood collection, etc. When sleeping with a jugular vein indwelling catheter, try to lie on your back, or lie on the opposite side of the catheter, to avoid large-scale activities and compressing the catheter to affect blood flow.
When sitting with femoral vein indwelling catheter, the body should not lean forward, and the angle between the body and the leg should not be less than 90 degrees to prevent deformation and discounting of the catheter.
After the end of dialysis, the medical staff need to seal the catheter with positive pressure in time, close the catheter clip, and do not switch it on and off by itself to avoid thrombosis and infection.
To prevent bleeding and catheter dislodgement:
Be gentle when putting on and taking off your clothes to avoid accidentally pulling out the catheter. Once the catheter is pulled out, you should immediately press the local area to stop the bleeding and contact the medical staff in time.
Patients with indwelling catheters in the jugular vein should try to avoid wearing pullover clothes. Patients with indwelling catheters in the femoral vein should not be too active. Avoid pulling the catheter out when putting on and taking off pants. A zipper can be installed on the indwelling catheter.
Topical dressings to keep dry:
Generally, only medical personnel can open and handle it, and avoid scratching and grasping the part of the tube at ordinary times. If some auxiliary materials are found to be open, it is necessary to disinfect and replace the dressing in time. Patients are not allowed to take a bath during catheterization, and special waterproof dressings are required for showering.
