Basic Intravenous
Therapy
90-95% of patients in the
hospital receive some type
of intravenous therapy.
This presentation will enhance your
knowledge of how to care for them.

 Veins are unlike arteries in
that they are 1)superficial,
2) display dark red blood at
skin surface and 3) have no
pulsation
 Vein Anatomy
- Tunica Adventitia
- Tunica Media
- Tunica Intima
- Valves
Vein Anatomy and Physiology

3. Previous Next
Tunica Adventitia
the outer layer of the vessel
 Connective tissue
 Contains the
arteries and veins
supplying blood to
vessel wall

4. Previous Next
Tunica Media
the middle layer of the vessel
 Contains nerve
endings and muscle
fibers
 The vasoconstrictive
response occurs at
this layer

5. Previous Next
Tunica Intima
the inner layer of the vessel
One layer of endothelials
No nerve endings
Surface for platelet aggregation
w/trauma and recognition of
foreign object at this level
PHLEBITIS begins here

6. Previous Next
Valves
present in MOST veins
 Prevent backflow and
pooling
 More in lower extremities
and longer vessels
 Vein dilates at valve
attachment

7. Previous Next
Veins of the Upper Extremities
Digital Vessels
-Along lateral aspects fingers, infiltrate
easily, painful, difficult to immobilize and
should be your LAST RESORT
Metacarpal Vessels
-Located between joints and
metacarpal bones (act as natural splint)
-Formed by union of digital veins
-Geriatric patients often lack enough
connective / adipose tissue and skin
turgor to use this area successfully
Digital

8. Previous Next
Veins of the Upper Extremities
 Cephalic (Intern’s Vein)
-Starts at radial aspect of wrist
-Access anywhere along entire length
(BEWARE of radial artery/nerve)
 Medial Cephalic (“On ramp” to
Cephalic Vein)
-Joins the Cephalic below the elbow
bend
-Accepts larger gauge catheters, but
may be a difficult angle to hit and
maintain

9. Previous Next
Veins of the Upper Extremities
 Basilic
- 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 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

10. Previous Next
Purposes 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 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)
- PROTECTIV ® -ACUVANCE ®

11. Previous Next
Starting a Peripheral IV
 Finding 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)

12. Previous Next
IV Start Pain Management
One of the most frequent contributors to patient dissatisfaction is
painful phlebotomy and IV starts
• 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

13. Previous Next
Flushing Peripheral IV’s
Use prefilled saline and heparin flush syringes located in PYXIS
Heparin flush concentrations available:
-100u/ml (5ml in a 10ml syringe)
-10u/ml (2ml in a 3ml syringe)
Flushing intervals and amounts
- Peds: q 6hrs.
<22ga 1ml 0.9%NS followed by 1ml heparinized
(10units/ml) saline
- Adults: q 8hrs
w/1ml. 0.9%NS [3ml heparinized saline for OB]

14. Previous Next
Dressing/Bag Changes
Physician orders are
required if a peripheral
catheter is left in the same
site for more than 3 days.
It is best to have the
pharmacy add medications
to the infusion bags under
laminare flow to reduce
contamination

•Infiltration
•Phlebitis
•Thrombosis
•Cellulitis
•Septicemia

20. Previous Next
Infiltration/Extravasation
The most common cause is damage to the
wall during insertion or angle of placement.
STOP INFUSION and treat
as indicated by Pharmacy,
Medication package insert
or drug reference book.
Notify MD and document

21. Previous Next
Phlebitis/Thrombophlebitis
 Chemical
- Infusate chemically 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

22. Previous Next
Cellulitis
 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
- Treated w/antibiotics

23. Previous Next
Septicemia/Pulmonary Edema/
Embolism
 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

24. Previous Next
 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.

IV 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
