Nontunneled Percutaneous Central Catheters4. Tunneled Central Catheters5. Implanted PortsIntroductionVenous Access Devices (VAD’s), allow access to large veins for the purpose of administering intravenous solutions and some also allow for aspiration of blood samples. Use of a VAD avoids repeated venipuncture, and because it uses larger vessels than a peripheral IV, there is less chance of drug extravasation. Selection of which VAD is used depends on:1. Duration of therapy2. Complexity of the treatment 3. Length of treatment 4. The patient’s acceptance of the device5. The patient’s ability to provide care.1. Peripherally Inserted Central Catheters (PICC’s)These catheters are usually made of polymers and are generally used when immediate central venous access is needed. These catheterscan be used for infusion therapy when peripheral intravenous lines can not be used. They are nontunneled catheters and are inserted at or just above the antecubital fossa and are threaded up the arm so that the tip is in the distal one third of the superior vena cava. The line can be up to 60 cm and come in various gauges. Generally, a single or double lumen catheter.Advantages:Peripherally insertedCan be inserted at the bedside or in interventional radiology (by physician)Insertion can be performed by specially trained nurses Excellent for continuous infusion for up to several monthsDisadvantages:Requires external dressing care at the siteRisk of occlusion if not flushed with saline and heparin properlyRisk of phlebitis (not as great as with a peripheral IV) 7-10 days after insertionLong line to central venous circulation.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
