1. Prevent the catheter from becoming dislodged. 2. It is advisable to wear loose-fitting, low‑necked or collarless clothing. 3. When putting on or taking off clothes, avoid making overly large turning motions or performing abrupt movements to prevent pulling on, irritating, or dislodging the catheter. 4. If the catheter becomes dislodged, immediately apply firm pressure to the site to stop bleeding for at least 15 minutes. If you experience any discomfort or persistent bleeding, seek medical attention promptly.
Self-Care Guidelines for Patients with Central Venous Catheters
1. Prevent catheter dislodgement
2. It is advisable to wear loose-fitting, low-necked or collarless clothing.
3. When putting on or taking off clothing, avoid excessive twisting and abrupt movements to prevent traction, inadvertent displacement of the catheter, or catheter removal.
4. If the catheter becomes dislodged, immediately apply firm pressure to the wound to stop the bleeding for at least 15 minutes. If you experience any discomfort or if the bleeding does not stop, seek medical attention promptly.
Prevent catheter occlusion
1. Be careful not to do heavy physical labor.
2. Maintain regular bowel movements.
3. During sleep, assume a supine position or lie on the side opposite the catheter.
4. Bend over as little as possible to prevent blood from flowing backward.
5. Follow your doctor’s prescription and take anticoagulant medications on schedule to reduce the incidence of catheter occlusion.
Prevent wound infection
1. When washing your hair or bathing, avoid getting the dressing wet.
2. In summer, try to avoid sweating as much as possible.
3. Once the dressing becomes wet, disinfect and replace it promptly.
4. Change the dressing with each dialysis session.
5. Prevent catheter displacement
Preoperative Nursing Guidelines for Arteriovenous Fistula Surgery
1. Ensure proper protection of the surgical limb’s vessels and skin in advance.
2. Generally, the surgical procedure is performed on the limb with less activity.
3. Avoid drawing blood, administering intravenous fluids, or measuring blood pressure in the affected limb.
4. It is best to begin fist-clenching exercises two weeks before surgery to help promote vascular engorgement.
Postoperative Care Guidelines for Arteriovenous Fistula Surgery
1. After returning to the ward, when lying in bed, the affected limb should be elevated.
2. When standing or sitting, the arms should be positioned at chest height.
3. Keep the elbow joint at an angle greater than 90 degrees to promote blood circulation and reduce edema.
4. If you notice bleeding from the wound or redness, swelling, or pain, inform your doctor promptly.
5. Keep the wound clean and dry.
6. After surgery, self‑check the arteriovenous fistula for patency, and dynamically compare the intensity of the thrill and the loudness of the vascular bruit.
Patency: palpable thrill and audible vascular bruit
Obstruction: The vessel appears as a cord-like structure, with no thrill and no murmur; seek medical attention promptly and report to your physician.
7. Wear loose-fitting clothing with wide cuffs to avoid compressing the fistula‑bearing limb, and refrain from lifting heavy objects with that limb.
8. Blood draws, infusions, injections, and blood pressure measurements must not be performed on the limb on the side of the arteriovenous fistula.
