CHOOSING AN IV SITE
Many sites can be used for IV therapy, but ease of access
and potential hazards vary.
peripheral locations
ordinarily only sites used by nurses
arm veins are most commonly used coz safe and easy to enter
arm veins
metacarpal, cephalic, basilic, and median veins
More distal sites should be used first, with more proximal
sites used subsequently.
7/27/2019 Parenteral Fluid
39/145
CHOOSING AN IV SITE
Avoid the following
Leg veins because of high risk of thromboembolism.
veins distal to a previous IV infiltration or phlebitic area, sclerosed
or thrombosed veins,
arm with arteriovenous shunt or fistula arm affected by edema, infection, blood clot, or skin breakdown.
arm on side of mastectomy because of impaired lymphatic flow.
7/27/2019 Parenteral Fluid
40/145
Central veins
commonly used by physicians
subclavian and internal jugular veins.
Can gain access to (or cannulate) even when peripheral sites have
collapsed allow for administration of hyperosmolar solutions.
Hazards are much greater
7/27/2019 Parenteral Fluid
41/145
Consider mobility
Inspect both arms and hands and choose the site that does not
interfere with mobility.
antecubital fossa is avoided : except as a last resort.
Take note from far to near most distal site of the arm or hand is generally used first so that
subsequent IV access sites can be moved progressively upward.
7/27/2019 Parenteral Fluid
42/145
factors to consider when selecting a site
for venipuncture: Condition of the vein
Type of fluid or medication to be infused
Duration of therapy
Patients age and size Whether the patient is right- or left-handed
Patients medical history and current health status
Skill of the person performing the venipuncture
7/27/2019 Parenteral Fluid
43/145
After applying a tourniquet, the nurse palpates and
inspects the vein.
The vein should feel firm, elastic, engorged, and round,
not hard, flat, or bumpy.
Because arteries lie close to veins in the antecubital
fossa, the vessel should be palpated for arterial pulsation
(even with a tourniquet on), and cannulation of pulsating
vessels should be avoided.
7/27/2019 Parenteral Fluid
44/145
General guidelines for selecting a cannula
include: Length: 34 to 1.25 inches long
Diameter: narrow diameter of the cannula to occupy minimal
space within the vein
Gauge:
20 to 22 gauge for most IV fluids; a larger gauge for caustic or viscous
solutions
14 to 18 gauge for blood administration and for trauma patients and
those undergoing surgery
22 to 24gauge for elderly
Note: Hand veins are easiest to cannulate.
Cannula tips should not rest in a flexion area (eg, the antecubital
fossa) as this could inhibit the IV flow.
7/27/2019 Parenteral Fluid
45/145
PREPARING THE IV SITE
Before preparing the skin, ask patient allergy to latex or
iodine
Excessive hair at selected site may be removed by
clipping
to increase the visibility of the veins and
to facilitate insertion of the cannula and adherence of dressings to
the IV insertion site.

Site preparation
1. Cleanse infusion site
The insertion site is scrubbed with a sterile pad soaked in 10%
povidoneiodine (Betadine) or chlorhexidine gluconate solution for 2 to
3 minutes
from the center of the area to the periphery
Allow the area to air day.
site should not be wiped with 70% alcohol because the alcohol negates the effect of the disinfecting solution
Alcohol pledgets are used for 30 seconds instead, only if the patient is allergic
to iodine
2. Excessive hair at selected site should be clipped with scissor .
7/27/2019 Parenteral Fluid
59/145
Maintain sterility of equipment
IV device, the fluid, the container, and tubing must be sterile
Because infection can be a major complication of IV therapy
perform hand hygiene
put on gloves: nonsterile disposable gloves

FACTORS AFFECTING FLOW
Height of container
Flow is directly proportional to the height of the liquid column.
Raising the height of the infusion container may improve sluggish
flow.
Diameter of tubing and cannula
Flow is directly proportional to the diameter of the tubing.
The clamp on IV tubing regulates the flow by changing the tubing
diameter.
flow is faster through large-gauge rather than small- gauge
cannulas.
7/27/2019 Parenteral Fluid
75/145
FACTORS AFFECTING FLOW
Length of tubing Flow is inversely proportional to the length of the tubing.
Adding extension tubing to an IV line will decrease the flow.
Viscosity
Flow is inversely proportional to the viscosity of a fluid.
viscous IV solutions (ex: blood) require a larger cannula than water
or saline solutions

DISCONTINUING AN INFUSION
The nurse never use scissors to remove the tape ordressing.
Apply pressure to the site for 2 to 3 minutes using a dry,
sterile gauze pad.
Inspect the catheter for intactness.
The arm or hand may be flexed
or extended several times.
7/27/2019 Parenteral Fluid
81/145
DISCONTINUING AN INFUSION
The removal of an IV catheter is associated with twopossible dangers:
bleeding
catheter embolism
To prevent excessive bleeding dry, sterile pressure dressing should be held over the site as the
catheter is removed.
Firm pressure is applied until hemostasis occurs.
7/27/2019 Parenteral Fluid
82/145
Catheter embolism Preventive measures
Avoid using scissors near the catheter.
Avoid withdrawing the catheter through the insertion needle.
Follow the manufacturers guidelines carefully (eg, cover the needle
point with the bevel shield to prevent severance of the catheter).
Management
If the catheter clearly has been severed, the nurse can attempt to
occlude the vein above the site by applying a tourniquet to prevent the
catheter from entering the central circulation (until surgical removal is
possible). As always, however, it is better to prevent a potentially fatalproblem than to deal with it after it has occurred

Closely monitoring the insertion site is necessary to detectinfiltration before it becomes severe.
How to check?
insertion area is largerthan same site of the opposite extremity
Backflow of blood into tubing proves that the catheter is properlyplaced within the vein. True or false?
If the catheter tip has pierced the wall of the vessel, however, IV fluid
will seep into tissues as well as flow into the vein.
Although blood return occurs, infiltration has occurred as well.
7/27/2019 Parenteral Fluid
93/145
Closely monitoring the insertion site is necessary to detectinfiltration before it becomes severe.
How to check?
apply a tourniquet above (or proximal to) infusion site and
tighten it enough to restrict venous flow. If the infusion continues to drip despite the venous obstruction,
infiltration is present.

118/145
Clotting and Obstruction
Blood clots may form in the IV line as a result of kinked IV tubing
very slow infusion rate
Empty IV bag
failure to flush the IV line after intermittent medication or solutionadministrations.
The signs are decreased flow rate and blood backflow
into the IV tubing.
Management
7/27/2019 Parenteral Fluid
119/145
Management
If blood clots in the IV line DC infusion
Restart another site with a new cannula and administration set.
The tubing should not be irrigated or milked. Neither the infusion
rate nor the solution container should be raised, and the clot should
not be aspirated from the tubing
Prevention
7/27/2019 Parenteral Fluid
120/145
Prevention
Do not permit IV solution bag to run dry Tape the tubing to prevent kinking and maintain patency
Maintain adequate flow rate
Flushing line after intermittent medication or other solution
administration.
In some cases, a specially trained nurse or physician
may inject a thrombolytic agent into the catheter to clear
an occlusion resulting from fibrin or clotted blood.

Fluid Overload
7/27/2019 Parenteral Fluid
125/145
Fluid Overload
Overloading the circulatory system with excessive IVfluids causes increased blood pressure and central
venous pressure.
Fluid Overload S/S
7/27/2019 Parenteral Fluid
126/145
Fluid Overload S/S
moist crackles on auscultation of the lungs Edema
weight gain
Dyspnea
respirations : shallow and increased rate.
Fluid Overload causes
7/27/2019 Parenteral Fluid
127/145
Fluid Overload causes
rapid infusion of an IV solution or hepatic, cardiac, orrenal disease.
risk for fluid overload and subsequent pulmonary edema
is especially increased in elderly patients with cardiac
disease; this is referred to as circulatory overload.
Management
7/27/2019 Parenteral Fluid
128/145
Management
Decrease IV rate Monitor VS frequently
Assess breath sounds
Place patient in high Fowlers position
Contact physician immediately.
Prevention

Septicemia and Other Infection
Pyrogenic substances in either the infusion solution or theIV administration set can induce a febrile reaction and
septicemia.
S/s
7/27/2019 Parenteral Fluid
135/145
S/s
abrupt temperature elevation shortly after the infusion isstarted
Backache
Headache
increased pulse and respiratory rate
Nausea and vomiting
Diarrhea
chills and shaking
general malaise.
In severe septicemia:
vascular collapse and septic shock
Causes of septicemia
7/27/2019 Parenteral Fluid
136/145
Causes of septicemia
contamination of the IV product or a break in aseptictechnique
especially in immunocompromised patients.
Management
7/27/2019 Parenteral Fluid
137/145
Management
Treatment is symptomatic culturing of the IV cannula, tubing, or solution if suspect
establishing a new IV site for medication or fluid
administration.

Infection ranges in severity from local involvement of theinsertion site to systemic dissemination of organisms
through the bloodstream, as in septicemia.
Measures to prevent infection are essential at the time the
IV line is inserted and throughout the entire infusion.
Prevention
7/27/2019 Parenteral Fluid
139/145
Prevention
Careful hand hygiene before every contact with any partof the infusion system or patient
Examine the IV containers for cracks, leaks, or
cloudiness, which may indicate a contaminated solution
Use strict aseptic technique
Prevention
7/27/2019 Parenteral Fluid
140/145
Prevention
Firmly anchor the IV cannula to prevent to-and-fromotion
Inspect the IV site daily and replace a soiled or wet
dressing with a dry sterile dressing. (Antimicrobial agents
that should be used for site care include 2% tincture of
iodine, 10% povidoneiodine, alcohol, or chlorhexidine,
used alone or in combination.
Prevention
7/27/2019 Parenteral Fluid
141/145
Prevention
Remove the IV cannula at the first sign of localinflammation, contamination, or complication
Replace the peripheral IV cannula every 48 to 72 hours,
or as indicated
Replace the IV cannula inserted during emergencyconditions
(with questionable asepsis) as soon as possible
Prevention

142/145
Prevention
Use a 0.2-micron air-eliminating and bacteria/particulateretentive filter with non-lipid-containing solutions that
require filtration.
The filter can be added to the proximal or distal end of the
administration set.
If added to the proximal end between the fluid container and the
tubing spike, the filter ensures sterility and particulate removal from
the infusate container and prevents inadvertent infusion of air.
If added to the distal end of the administration set, it filters air
particles and contaminants introduced from add-on devices,
secondary administration sets, or interruptions to the primary
system

Replace solution bag and administration set inaccordance with agency policy and procedure
Infuse or discard medication or solution within 24 hours of
its addition to an administration set
Change primary and secondary continuous administrationsets every 72 hours, or immediately if contamination is
suspected
Change primary intermittent administration sets every 24
hours, or immediately if contamination is suspected
