Central Venous Access (CVA) at Gertrude's Children's Hospital

Overview

Overview

  • What is Central Venous Access (CVA)?: A medical procedure where a catheter (thin, flexible tube) is inserted into a large vein in the neck, chest, or groin to provide direct access to the bloodstream.
  • Why is CVA used?: To:
    • Administer medications, nutrients, or fluids over an extended period
    • Draw blood samples for laboratory tests
    • Monitor central venous pressure (CVP) to guide fluid management and hemodynamic support
    • Provide dialysis or apheresis therapy

Detailed Explanation

Step-by-Step Process

  1. Preparation
    • A trained healthcare team from Gertrude’s Children’s Hospital prepares the necessary equipment.
    • The child is positioned comfortably, and the skin is cleaned and prepared.
  2. Site Selection and Anesthesia
    • The healthcare provider selects the most suitable vein for CVA (e.g., internal jugular, subclavian, or femoral vein).
    • Local anesthesia or sedation may be used to minimize discomfort.
  3. Procedure
    • The healthcare provider uses ultrasound guidance (if available) to locate the vein and insert the catheter.
    • The catheter is advanced through the vein until the tip reaches the superior or inferior vena cava.
  4. Verification and Securing
    • The catheter’s position is confirmed using X-ray or ultrasound.
    • The catheter is secured with sutures, tape, or a securement device to prevent movement.

Types of Central Venous Access Devices

  • Peripherally Inserted Central Catheter (PICC): Inserted through a vein in the arm, guided to the superior vena cava.
  • Tunneled Central Venous Catheter (Hickman/Broviac): Inserted through a vein in the neck or chest, with a tunneled segment under the skin.
  • Implantable Port (Port-a-Cath): A completely implanted device, accessed through the skin with a special needle.
  • Non-Tunneled Central Venous Catheter (Temporary): Used for short-term access, often in emergency situations.

Equipment and Supplies Used

  • Central Venous Catheter (CVC) Kit: Contains the catheter, guidewire, and other necessary components.
  • Ultrasound Machine: Facilitates vein localization and reduces complications.
  • X-ray or Fluoroscopy: Confirms catheter placement.
  • Suture, Tape, or Securement Device: Secures the catheter in place.

Potential Risks and Benefits

  • Benefits:
    • Provides reliable, long-term access for medication administration and blood sampling
    • Enables precise monitoring of central venous pressure (CVP)
    • Supports nutritional therapy and fluid management
  • Risks:
    • Infection (e.g., catheter-related bloodstream infection, CRBSI)
    • Bleeding or hematoma at the insertion site
    • Catheter malposition, occlusion, or breakage
    • Venous thrombosis or stenosis
