Peripheral Access
![Page 3: Vascular access](https://reader033.vdocument.in/reader033/viewer/2022052901/556e3c8ad8b42a16278b4ad5/html5/thumbnails/3.jpg)
Peripheral Access is obtained using Aseptic technique
Initial insertion attempts should begin distally and progress up the extremity◦ If the situation and pt vasculature allow
During resuscitation peripheral access is preferred to eliminate interruption in chest compression for central line insertion
Proximal veins may be used when giving medication with extremely short half life, or for rapid fluid or CT contrast infusion ◦ Adenosine
Scalp Veins have no valves and are easily visible on infants- allowing infusion in both directions
Tips and Tricks

Infiltration of fluid or medication (can cause necrosis with certain meds)
Phlebitis Embolism
◦ Of blood, air, or catheter fragments Infection Cellulitis Needle stick and blood exposure for
RN
Potential Complications

In ER- anywhere you can find a vein◦ Arms, legs, Neck, Abdomen,
Hands, Feet, Breasts etc… Most Common are
◦ Hands, A/C (antecubital), Forearms, and EJ’s (external Jugular)
Just make sure to always point toward the heart
**note: check with your facility for specific locations and protocols

Size and Type of cath are determined by urgency of need, patient size and vasculature◦ Larger Diameter (12,14,16,18g)- used for rapid
fluid, drug, or blood infusion◦ Smaller Catheter (20,22,24g)- are used for routine
vascular access, and patients with smaller veins
Catheter Selection

Subclavian Vein- under the clavicle
Internal Jugular- also under the clavicle
Femoral Vein- In the groin
Where are they placed?

Why do we place them?
Short Term Long Term
When all other peripheral access is unavailable
When condition is unstable and requires hemodynamic monitoring (eg CVP)
Prolonged IV Therapy◦ TPN, extended Abx
therapy, or caustic medication administration Vancomycin
Debilitating diseases
◦ AIDS, Cancer

Inserted in to the bone marrow, blood can be drawn from the marrow, and fluids, medication, and blood infused through the marrow
Used on adults and pediatric patients
When all else fails…

Anterior Tibia, Medial Malleolus, Sternum, Distal Femur, Humerus, or Iliac Crest
Where do we place them?

Fluid and Blood Replacement
![Page 19: Vascular access](https://reader033.vdocument.in/reader033/viewer/2022052901/556e3c8ad8b42a16278b4ad5/html5/thumbnails/19.jpg)
Example Uses
Isotonic 0.9% Normal Saline (NS),Lactated Ringers
Expands intravascular volume, used for hydration, and maintenance fluid
Hypotonic NS 0.45%NS 0.2%Dextrose 5% in Water (D5W)
Shifts H2O intracellular, assessing renal patients,and mixing medications
Hypertonic D5% in NSD10% in NS
D10% in WaterD10% in 0.45%NSD20% in Water
Shifts intra cell fluid to extracellular, used in too much hypotonic solution administration
Maintenance to promote diuresis
Maintenance IV Fluid

Whole Blood◦ Unfiltered and carries significant risks of
infection and transmission, is expensive, and not readily available
PRBC’s (Packed Red Blood Cells)◦ Are used most often for blood replacement
FFP (Fresh Frozen Plasma)◦ Contains Clotting Factors
Albumin (5% isoonocoit, 25% isotonic “salt poor”)◦ Used as volume expander when risk of
interstitial edema is great (pulmonary/cardiac disease)
