Notes for the use of disposable sterile hemodialysis catheter and accessory long-term hemodialysis catheter  

Disposable blood sterile hemodialysis catheter and accessories Disposable sterile hemodialysis catheter product performance structure and composition this product is composed of a soft tip, a connecting seat, an extension tube and a cone socket;  The catheter is made of medical polyurethane and polycarbonate. It is single cavity, double cavity and three cavity catheter.  This product is clinically used for hemodialysis and infusion.  Specifications model double cavity, three cavity
Tunnel duct with dacron jacket  

With the aging of society, high blood pressure, diabetes, coronary heart disease (CHD) with renal failure patients increased, vascular condition is poor, autogenous arteriovenous internal fistula significantly higher incidence of complications, seriously affect the patient’s dialysis treatment effect and quality of life, so take polyester belt tunnel catheter or catheter for a long time, has been widely used in the world, its advantage is:  The catheter has good biocompatibility, and the catheter can be fixed firmly with the skin. Its polyester sleeve can form a closed bacterial barrier in the subcutaneous tunnel, reducing the occurrence of infection and greatly prolonging the use time.
Use and maintenance of hemodialysis catheters  

1. Nursing and evaluation of catheters  

1. Catheter skin outlet  

Before and after each use, the appearance of the skin outlet at the intubation site should be evaluated for redness, secretion, tenderness, bleeding and exudation, etc.  If it is a temporary catheter, check the fixation of the suture needle. If it is a long-term catheter, observe whether the CAFF is pulled or protruded.  

2. Outer joint of catheter  

Whether there is rupture or break, the degree of patency of the lumen, if insufficient blood flow is found, it should be reported to the doctor in time, and the thrombus and fibrin sheath formation in the catheter should be determined by ultrasound, imaging and other means.  

3. Patient signs  

Whether the symptoms and degree of fever, chills, pain and other complaints of discomfort.  

2. Connection operation process  

1. Preparation  

(1) The dialysis machine has passed the self-check, the dialysis pipeline has been pre-flushed and is in the standby state.  

(2) Preparation: treatment cart or treatment tray, disinfection articles (iodophor or chlorhexidine), sterile articles (treatment towel, gauze, syringe, cleaning gloves, etc.).  

(3) The patient should be placed in a comfortable supine position, and the patient with neck intubation should wear a mask to expose the intubation position.  

2. Procedure  

(1) Open the outer dressing of the central venous catheter.  

(2) Wear gloves.  

(3) Open 1/4 side of the sterile treatment towel and place it under the double-lumen catheter of the central vein.  

(4) Screw disinfection of catheter protection cap, catheter mouth and catheter clamp for 2 times respectively.  

(5) Check that the catheter clamp is clamped, remove the nut, and discard it.  Place the sterilized catheter on the 1/2 sterile side of the treatment towel.  

(6) Disinfect the nozzle again before operation.  

(7) 2mL intracatheter sealing heparin solution was pumped back with a 2-5ml syringe and pushed onto the gauze.  

(8) Check whether there are clots on the gauze. If there are clots, extract 1ml again and push the injection.  The distance between the injection and gauze is greater than 10cm.  

(9) After judging that the catheter is unobstructed, connect the artery and vein pipelines of extracorporeal circulation to establish extracorporeal circulation.  

3. End the tube sealing operation after dialysis  

(1) After the treatment and blood return, clamp the catheter clamp, disinfect the arteriovenous catheter joint, and disconnect the joint with the circulation pipeline.  

(2) Disinfect the inlet of the artery and vein of the catheter respectively, and push 10ml normal saline to rinse the catheter by pulse method. After naked eye observation, there was no blood residue in the exposed part of the catheter, push anticoagulant sealing fluid by pellet as instructed by the doctor.  (3) Use a sterile heparin cap to seal the opening of the arteriovenous tube and double layers of sterile gauze to wrap it.  Fixed.  

3. Dressing change of central venous catheter  

1. Check whether the dressing is dry, blood and stains.  

2. Wear gloves.  

3. Open the dressing and check whether there is bleeding, exudation, redness and swelling, skin damage and suture shedding at the place where the central venous catheter is placed.  

4. Take a iodophor cotton swab and rotate it clockwise to disinfect the place where the tube has been inserted. The disinfecting range is 8-10cm.  

5. Paste the wound dressing on the skin at the place where the tube is placed, and indicate the dressing change time.  Use and maintenance of catheters
