Veins of the Upper ExtremitiesVeins of the Upper Extremities
Cephalic (Intern’s Vein)Cephalic (Intern’s Vein) -Starts at radial aspect of wrist -Access anywhere along entire
-Accepts larger gauge catheters, but may be a difficult angle to hit and maintain

Veins of the Upper ExtremitiesVeins of the Upper Extremities BasilicBasilic - Originates from the ulner side
of the metacarpal veins and runs along the medial aspect of the arm. It is often overlooked becauses of its location on the “back” of the arm, but flexing the elbow/bending the arm brings this vein into view
Medial BasilicMedial Basilic - Empties into the Basilic vein
running parallel to tendons, so it is not always well defined. Accepts larger gauge catheters.
- BEWARE of Brachial Artery/Nerve

Purposes of IV TherapyPurposes of IV Therapy To provide parenteral nutrition To provide avenue for dialysis/apheresis To transfuse blood products To provide avenue for hemodynamic monitoring To provide avenue for diagnostic testing To administer fluids and medications with the ability to
rapidly/accurately change blood concentration levels by either continuous, intermittent or IV push method.
Types of Peripheral Venous Access DevicesTypes of Peripheral Venous Access Devices•Butterfly (winged) or Scalp vein needles (SVN) – not recommended for non compliant patient as it can easily penetrate the vein wall causing extravasation. We use these frequently for phlebotomy•Safety Over the needle catheters (ONC)

Starting a Peripheral IVStarting a Peripheral IV Finding a vein can be challengingFinding a vein can be challenging
- Go by “feel”, not by sight. Good veins are bouncy to the touch, but are not always visible.
- Use warm compresses and allow the arm to hang dependently to fill veins.
- A BP cuff inflated to 10mmHg below the known systolic pressure creates the perfect tourniquet. Arterial flow continues with maximum venous constriction.
- If the patient is NOT allergic to latex, using a latex tourniquet may provide better venous congestion
- Avoid areas of joint flexion- Start distally and use the shortest length/smallest gauge access
device that will properly administer the prescribed therapy
(BE AWARE: Blood flow in the lower forearm and hand is 95ml/min)

• Use 25-27g insulin syringe to create a wheal similar to a TB skin test on top of or just to side of vein with 0.1 -0.2 ml normal saline or 1% xylocaine without epinephrine
• Topical anesthesia cream (ie EMLA) may be applied to children>37 weeks gestation 1 hr. prior to stick. It might be a good idea to anesthetize a couple of sites
• Have the patient close their fist (NO PUMPING) prior to stick
• Make sure the skin surface cleansing agent (alcohol/chlorhexidine) is dry prior to stick. Drawing this into the vein may stimulate the vasoconstrictive action of the tunica media layer

erodes internal layers. Warm compresses may help while the infusate is stopped/changed. Anti-inflammatory and analgesic medications are often used no matter what the cause Mechanical
- Caused by irritation to internal lumen of vein during insertion of vascular access device and usually appears shortly after insertion. The device may need to be removed and warm compresses applied
Bacterial- Caused by introduction
of bacteria into the vein. Remove the device immediately and treat w/antibiotics. The arm will be painful, red and warm; edema may accompany

CellulitisCellulitis
Inflammation of loose connective tissue around insertion site.
- Caused by poor insertion technique
- Red swollen area spreads from insertion site outwardly in a diffuse circular pattern
Septicemia- Severe infection that occurs to a system or entire body- Most often caused by poor insertion technique or poor site
care- Discontinue device immediately, culture and treat
appropriately Pulmonary edema- caused by rapid infusion Pulmonary embolism - Caused by any free floating substances that require thrombolytic therapy for several months. Increased risk w/lower ext. Air embolism- caused by air injected into IV system. Keep insertion site below level of heart

Vascular access device will not flush/can’t draw blood- Evaluate for kink in tubing or catheter tip against vein wall.
Vascular access device (VAD) leaking when flushed - Verify that hub access cap is connected correctly
Patient complains of pain while VAD being flushed- Assess for infiltration
VAD broken- PICC’s may be repaired. All other devices must be replaced
Call IV therapy team member for any concerns or questions.
RN’s and LPN’s can start peripheral IV’s after initial training and observation by preceptor
LPN’s CANNOT infuse blood products or high risk IV medications.

IV Medication AdministrationIV Medication Administration Many medications require patient monitoring that cannot be done on units where the nurse/patient ratios are greater than 1:2
A patient can be moved to a unit where the ratio is appropriate for invasive/frequent monitoring or another nurse can be brought to care for the patient during the med administration
All Medications Cannot Be Administered on All Units
General Care Units:Can give meds requiring only basic physical assessment data Stepdown Units:Can give meds that require more invasive or frequent monitoring than is available on general care unitsIntensive Care Units: Can give meds that require more invasive or frequent monitoring than is available on the Stepdown units.

See “APPROVED FOR” section. You will find if the medication can be administered on your unit.
