Pre-Procedure Preparation:
Permacath placement refers to the insertion of a Permacath, a type of tunneled hemodialysis catheter, designed for long-term use in patients who require dialysis. The Permacath is typically inserted into a large central vein, such as the internal jugular vein in the neck or the subclavian vein in the chest, and is tunneled under the skin to exit at a different site from where it enters the vein. This tunneling helps reduce the risk of infection and provides a more secure and comfortable catheter for the patient.
Procedure for Permacath Placement:
Pre-Procedure Preparation:
- The patient is usually given a local anesthetic to numb the insertion area. Sedation or general anesthesia may also be administered depending on the patient’s condition and preference.
- The skin over the insertion site is cleaned and sterilized to minimize the risk of infection.
- Using ultrasound guidance, a needle is inserted into the chosen vein (usually the internal jugular or subclavian vein).
- A guidewire is threaded through the needle and the needle is removed.
- A small incision is made near the vein entry point, and a tunnel is created under the skin to the exit site (usually a few inches away from the entry point).
- The catheter is then passed through this tunnel and into the vein over the guidewire.
- The catheter is advanced into the vein, with the tip positioned in the superior vena cava, a large central vein that carries blood to the heart.
- The correct placement of the catheter is often confirmed by X-ray.
- The catheter is secured at the exit site with sutures and covered with a sterile dressing.
- The tunneling and the presence of a cuff under the skin help to secure the catheter and reduce the risk of infection.
