Safety protection of hemodialysis catheterwith intravenous indwelling double lumen catheter
When the patient performs hemodialysis for the first time, or if there is no fistula for various reasons, the doctor will puncture a vein retention tube in the neck or thigh base according to the patient's condition to facilitate hemodialysis treatment. The safety protection of this pipeline is very important. Before and after each hemodialysis, the staff will carefully help the patient to clean and disinfect the punctured local skin, bandage and properly fix the pipeline, but the patient needs to do the protective work himself during non-dialysis. The following precautions are specially notified :
(1): Develop good hygiene habits, keep local dry and clean, and try to avoid showering to avoid infection after getting wet. Pay special attention when putting on and taking off clothes to avoid pulling the catheter out. Do not disassemble the bandaged gauze yourself to avoid local infection caused by puncture. If there is redness, swelling, heat, pain or fever, chills and other discomforts locally, you may already have an infection, and you should see a doctor in time.
(2): Except for the femoral vein indwelling catheter, it should not be too much activity, other activities are not restricted, but it should not be violent activity, in order to prevent the indwelling catheter from slipping out, once it slips, hemostasis should be compressed, please immediately press with a clean gauze or towel Puncture the mouth to stop bleeding, and immediately go to the hospital for treatment.
(3): Patients who choose femoral vein puncture should minimize walking, sitting for a long time, frequently squat to the toilet, and avoid prolonging knee puncture on the side limbs when lying prone, so as not to bend or block the indwelling catheter.
(4): The patient should pay attention not to inadvertently remove the indwelling tube due to local itching at the puncture site, causing bleeding and blood loss.
(5): Intra-jugular (or femoral) indwelling catheters in hemodialysis patients are generally not suitable for other uses, such as blood drawing and infusion, etc. If they must be used (such as patients need a lot of fluids or no other infusion channels, etc.), use After that, the tube must be sealed according to the treatment requirements of the catheter after hemodialysis to prevent blockage.
(6): Avoid twisting the pipeline under pressure, otherwise it is easy to cause thrombosis and cause the catheter to be blocked and cannot be used, and ensure that the switch clamp of the indwelling catheter is closed and the heparin cap at the end of the tube is tightened to avoid bleeding.
(7): Due to the long retention time of the temporary central venous catheter, the suture is easily broken, or the repelling effect of the human skin on the foreign body (suture) causes the suture to detach from the skin, causing the catheter to slip off, and the catheter can cause bleeding. Especially the femoral vein indwelling catheter. If the suture breaks, you should go to the hospital in time.
(8): There is a certain concentration of heparin in the indwelling lumen to prevent the lumen from being blocked. If your dialysis interval is more than four days, it is recommended that you come to our center for dressing change and re-sealing the tube with heparin.
