Venous Access Matthew L. Paden, MD Emory University Children’s Healthcare of Atlanta at Egleston Peripheral IV Butterfly & angiocaths – – Short catheters generally placed in forearm, hand or scalp veins Short term therapy and unable to handle caustic chemicals (chemotherapy) Peripheral Sites Veins of the Forearm 1. Cephalic vein 2. Median Cubital vein 3. Accessory Cephalic vein 4. Basilic vein 5. Cephalic vein 6. Median antebrachial vein Peripheral Sites Veins of the Hand 1. Digital Dorsal veins 2. Dorsal Metacarpal veins 3. Dorsal venous network 4. Cephalic vein 5. Basilic vein Peripheral IVs Try to cannulate the most distal veins first – Drugs or fluids put through the cannula may extravasate at the upstream failed cannula site Transillumination Topical nitropaste Infiltration Extravasation Extravasation Phlebitis Cellulitis Types of Central Vascular Access Devices Non-tunneling Tunneling Implanted Non-Tunneling Direct venipuncture through the skin into a selected vein. – – – Peripheral IV Peripherally inserted central catheter Percutaneous catheters Non-Tunneling - PICC Peripherally inserted central catheters (PICC) – Midline Central venous catheter inserted at or above the antecubital space and then advanced until the distal tip of the catheter is positioned at the superior vena cava or superior vena cava and right atrial junction. Non-tunneling - PICC Useful for patient receiving long term medication therapy, chemotherapy or TPN Used for frequent blood sampling Distal end positioned at the superior vena cava or junction of superior vena cava and right atrium Non-Tunneling - PICC Peripherally inserted central catheters (PICC) Non-Tunneling - Midlines Used for shorter term intravenous therapy (up to 4 weeks) Used for frequent blood sampling Distal end positioned at the proximal end of the upper extremity PICC versus Midline Non-Tunneling – PICC and Midline examples at the antecubital & above Non-Tunneling – CVC Percutaneous catheters Also known as: Central Venous Catheters (CVC) – – Subclavian, femoral or internal jugular Single, double or triple lumen Non-tunneling - CVC Tip advanced to superior vena cava or SVC and right atrium junction As with PICC, appropriate for patients requiring long term chemotherapy or TPN Non-tunneling CVC subclavian site Tunneling Hickman® Broviac® Groshong® Tunneling Inserted into a central vein via percutaneous venipuncture or cut down Catheter then tunneled under the skin in the subcutaneous tissue and exited in a convenient location Dacron cuff hold the catheter in place Tunneled Hickman Catheter Tunneling - Broviac® Similar to the Hickman catheter, but is of smaller size. This catheter is mostly used for pediatric patients. Tunneling - Groshong® Similar to Hickman® and Broviac® with closed ended patented 3-way valve. Implanted VADs - Ports Catheter attached to a self-sealing silicone septum surrounded by a titanium, stainless steal or plastic port Port sutured under the skin Some brand names: – – – Port-a-cath® Infus-a-port® Power Port ® Implanted VADs - Ports Catheter runs from port to superior vena cava at the right atrium No part of the device is exposed outside the body Can deliver chemotherapy, TPN, antibiotics, blood products and blood sampling Implanted VADs - Ports Can only be accessed with special needle called a HUBER needle Contains a deflecting, non-coring point Insertion Complications Inadvertent Arterial Puncture Hematoma Formation Extravasation Infection Phlebitis Pneumothorax Adult Insertion Complications Systemic Complications Infection Deep Vein Thrombosis Pulmonary Embolism Superior Vena Cava Syndrome Mechanical Complication Catheter tip migration Broken or damaged catheter Catheter occlusion Femoral Vein Adults – – – – DVT Excess infection risk “Potentially inaccurate CVP” Femoral Vein Kids – – – – – – Better risk profile Ease of insertion, compressible No difference in DVT – ref 1-2 Same infection risk (maybe lower) – ref 3-5 Accurately reflects RAP if no increase in abdominal pressures – ref 6-8 1.

Femoral anatomy Vein is medial to the artery – Froehlich’s theorem Superficial distal to inguinal ligament, then dives deep 0.5-2cm inferior to the inguinal ligament Quiz Question What are the anatomic landmarks to determine where to stick for the femoral vein in a pulseless patient? – – – – A. 1/3 of the distance from the anterior superior iliac spine to the pubic tubercle B. ½ the distance between the pubic tubercle and the anterior superior iliac spine C. 1/3 of the distance from the pubic tubercle and the anterior superior iliac spine D. None of the above Quiz answer D. None of the above The femoral ARTERY lies ½ the distance between the pubic tubercle and the anterior superior iliac spine. The femoral vein is 0.5-1.5 cm medial to this depending on the size of the patient. Straight vs. Frog leg “The optimal positioning of the leg can vary according to the preference of the operator.” – Discuss Procedure 30-45 degree angle to skin 2 methods – – Stick with negative pressure on syringe while entering and exiting Insert needle, and only negative pressure on removal Allows you to better stabilize the needle by resting your hand on the thigh Procedure Blood flash - Insert wire – Wire not going smoothly Needle no longer in vessel False tracking in subcutaneous tissue Thrombus Advancing into lumbar veins Small incision – Blade directed away from wire Procedure Twisting motion of dilation Remove dilator Advance catheter Remove wire Aspirate and flush all ports Secure line with sutures Sterile dressing Seldinger Technique Procedure Wheeler – “Confirmation of proper CVC position is required after placement of all CVC’s” Warnings If you hit the artery – pressure until hemostatic Wire should float – should never have resistance If can’t pull the wire through the needle – remove both wire and needle together so you don’t sheer off the wire Never let go of the wire Catheter tip “pointing too cephalad” – in lumbar veins Complications 74 of 89 (83%) – no complications Other 15 – minor bleeding/hematoma 94.4% success rate Median duration 5 days – – 21% <3 days 43% 4-7 days 26% 7-14 days 10% >14 days Long term – 8 leg swelling, 11 BSI Venkataraman, et al.
