True. Backflow of blood into the tubing proves that the catheter tip is properly placed within the vein and not outside the vein where it could cause infiltration.
4. Definition of IV therapy
It is an effective and efficient method of supplying fluid
directly into intravenous fluid compartment producing
rapid effect with availability of injecting large volume
of fluid more than other method of administration.
6. PURPOSE
• The choice of an IV solution depends on the purpose of
its administration.
• Restore or maintain F & E
• Administer meds
• Provide nutrition
• Transfusion
• Route for blood samples
16. VENIPUNCTURE DEVICES
• Equipment used to gain access to the vasculature
includes
• Cannulas
• needleless IV delivery systems
• peripherally inserted central catheter or midline catheter access
lines.
17. Venipuncture Devices: CANNULAS
• Most common peripheral access devices
• have an obturator inside a tube that is later removed.
“Catheter” and “cannula” : used interchangeably.
• main types of cannula devices available are those
referred to
• winged infusion sets (butterfly) with a steel needle or as over-the-
needle catheter with wings
• indwelling plastic cannulas inserted over a steel needle
• indwelling plastic cannulas inserted through a steel needle.
18. • Scalp vein or butterfly needles
• short steel needles with plastic wing handles
• Easy to insert
• but infiltration occurs easily
• because they are small and nonpliable,
• use should be limited to obtaining blood specimens or
administering bolus injections or infusions lasting only a few hours
• increase the risk for vein injury and infiltration.
19. • over-the-needle catheter
• less likely to cause infiltration
• available in long lengths
• well suited for placement in central locations.
• Parts:
• Intracatheters: Plastic cannulas inserted through a hollow needle
• Stylet

24. Venipuncture Devices: NEEDLELESS IV
DELIVERY SYSTEMS
• an effort to decrease needlestick injuries and exposure to
HIV, hepatitis, and other bloodborne pathogens
28. Venipuncture Devices: Peripherally Inserted Central
Catheter or Midline CatheterAccess Lines
• Patients who need moderate- to long-term parenteral
therapy
• For patients with limited peripheral access
• obese or emaciated patients, IV/injection drug users
• require IV antibiotics, blood, and parenteral nutrition.
• Requires median cephalic, basilic, and cephalic veins
• pliable (not sclerosed or hardened)
• not subject to repeated puncture.
• If these veins are damaged
• central venous access via the subclavian or internal jugular vein
• surgical placement of an implanted port or a vascular access
device
32. Nursing assessment
1- assess the solution:
2- Reading the label on the solution.
3- Determine the compatibility of all fluid and additives.
No leakage Sterile
No small
particles
Clear and
not
expired
34. • Also assess the patient for :
1- Any allergies and arm placement preference.
2- Any planned surgeries.
3- Patient’s activities of daily living.
4- Type and duration of I.V therapy, amount, and rate.
35. PREPARING TO ADMINISTER IV
THERAPY
• Before performing venipuncture
• hand hygiene
• applies gloves
• informs patient about procedure
• Select most appropriate insertion site and type of cannula
for a particular patient.
36.
37. Factors influencing choices of insertion
site
• type of solution to be administered
• expected duration of IV therapy
• patient’s general condition
• availability of veins
• skill of the person initiating the infusion
38. 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.
39. 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.
40. • 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
41. • 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.
42. factors to consider when selecting a site
for venipuncture:
• Condition of the vein
• Type of fluid or medication to be infused
• Duration of therapy
• Patient’s age and size
• Whether the patient is right- or left-handed
• Patient’s medical history and current health status
• Skill of the person performing the venipuncture
43. • 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.
44. General guidelines for selecting a cannula
include:
• Length: 3⁄4 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.
45. 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.
55. Planning
• Identify expected outcomes which focus on:
• preventing complications from I.V therapy.
• minimal discomfort to the patient.
• restoration of normal fluid and electrolyte balance .
• patient’s ability to verbalize complications.
57. Implementation during initiation phase
• Solution preparation
• Label the I.V container.
• Avoid the use of felt-tip pens or permanent markers on plastic
bag.
• Hang I.V bag or bottle
58. • Site preparation
1. Cleanse infusion site
• The insertion site is scrubbed with a sterile pad soaked in 10%
povidone–iodine (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 .
59. • 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
69. Implementation during maintenance
phase
• inspect the tubing.
• inspect the I.V set at routine intervals at least daily.
• Monitor vital signs .
• recount the flow rate after 5 and 15 minutes after
initiation
• Site care
• Dressings
• Tubing and bag changes
• Prevent complications
70. • Intermittent flushing of I.V lines
• Peripheral intermittent are usually flushed with saline (2-3 ml
0.9% NS.)
• Replacing equipments (I.V container, I.V set, I.V
dressing):
• I.V container should be changed when it is empty.
• I.V set should be changed every 24 hours.
• The site should be inspected and palpated for tenderness every
shift or daily/cannula should be changed every 72hours and if
needs.
• I.V dressing should be changed daily and when needed
72. MONITORING THERAPY
• Maintaining an existing IV infusion is a nursing
responsibility that demands knowledge of the solutions
being administered and the principles of flow.
• patients must be assessed carefully for both local and
systemic complications.
73. Monitoring Therapy
• Flow Rate
• Influences
• Height of container
• Diameter of tubing/cannula
• Length of tubing
• Viscosity
• Cannula position
• Position of extremity
• Site care
• dressings
• site change
• Tubing and bag changes
• Prevent complications
74. 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.
75. 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
• Cannula position
• Position of extremity
78. Evaluation
• Produce therapeutic response to medication, fluid and
electrolyte balance.
• Observe functioning and patency of I.V system.
• Absence of complications.
79.
80. DISCONTINUING AN INFUSION
• The nurse never use scissors to remove the tape or
dressing.
• 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.
81. DISCONTINUING AN INFUSION
• The removal of an IV catheter is associated with two
possible 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.
82. • Catheter embolism
• Preventive measures
• Avoid using scissors near the catheter.
• Avoid withdrawing the catheter through the insertion needle.
• Follow the manufacturer’s 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 fatal
problem than to deal with it after it has occurred
84. Recording and reporting:
• Type of fluid, amount, flow rate, and any drug added.
• Insertion site.
• Size and type of I.V catheter or needle.
• The use of pump.
• When infusion was begun and discontinuing.
• Expected time to change I.V bag or bottle, tubing,
cannula, and dressing.
85. • Any side effect.
• Type and amount of flush solution.
• Intake and output every shift, daily weight.
• Temperature every 4 hours.
• Blood glucose monitoring every 6 hours, and rate of
infusion.
86. Documentation
• Starting the IV
• 10/3/08 – 0900 hours – #22 1-inch Gelco inserted on first attempt to
R cephalic vein, NS infusing via pump at 125cc/hr. Pt tolerated
procedure well. S. Wise, RNC
• Discontinuing the IV
• 10/3/08 – 2000 hours – IV R wrist removed without difficulty, cathlon
intact. Pt tolerated well. S. Wise, RNC
90. Infiltration and Extravasation
• Infiltration : unintentional administration of a nonvesicant
solution or medication into surrounding tissue.
• occur when IV cannula dislodges or perforates the wall of
the vein.
91. Infiltration: S/S
• edema around insertion site
• leakage of IV fluid from insertion site
• discomfort and coolness in area of infiltration
• significant decrease in the flow rate
• When solution is particularly irritating, sloughing of tissue
may result.
92. • Closely monitoring the insertion site is necessary to detect
infiltration before it becomes severe.
• How to check?
• insertion area is larger than same site of the opposite extremity
• Backflow of blood into tubing proves that the catheter is properly
placed 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.
93. • Closely monitoring the insertion site is necessary to detect
infiltration 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.
94. Management
• infusion should be stopped
• IV discontinued
• a sterile dressing applied to the site after careful
inspection to determine the extent of infiltration.
• infiltration of any amount of blood product, irritant, or vesicant is
considered the most severe.
• Start another IV infusion at new site or proximal to
infiltration if same extremity is used.
95. Management
• warm compress to the site
• if small volumes of noncaustic solutions have infiltrated over a long
time
• cold compress
• ithe infiltration is recent
• Elevate affected extremity to promote the absorption of
fluid
• Use standardized infiltration scale to document the
infiltration (Infusion Nursing Standards of Practice)
96. Standardized infiltration scale
0 = No symptoms
1 = Skin blanched, edema less than 1 inch in any direction,
cool to touch, with or without pain
2 = Skin blanched, edema 1 to 6 inches in any direction, cool
to touch, with or without pain
3 = Skin blanched, translucent, gross edema greater than
6 inches in any direction, cool to touch, mild to moderate
pain, possible numbness
4 = Skin blanched, translucent, skin tight, leaking, skin
discolored, bruised, swollen, gross edema greater than 6 inches
in any direction, deep pitting tissue edema, circulatory
impairment, moderate to severe pain, infiltration of any
amount of blood products, irritant, or vesicant
97. Prevention
• Inspect site every hour for
• Redness
• Pain
• Edema
• blood return
• coolness at the site
• IV fluid draining from the IV site.
• Use appropriate size and type of cannula for vein
prevents this complication
98. Very Serious Complications Can Occur
• Infiltration
• Non vesicant solution
• Extravasation
• Vesicant solution
99. Extravasation
• similar to infiltration with an inadvertent administration of
vesicant or irritant solution or medication into the
surrounding tissue.
• Medications such as dopamine
• calcium preparations
• chemotherapeutic agents
• can cause pain, burning, and redness at the site
• Blistering, inflammation, and necrosis of tissues can
occur.
101. • The extent of tissue damage is determined by
• concentration of medication
• quantity that extravasated
• location of the infusion site
• tissue response
• duration of process of extravasation
102. Management
• Stop infusion
• Notify physician promptly.
• Initiate agency’s protocol for extravasation
• protocol may specify specific treatments, including
• Antidotes specific to the medication that extravasated
• IV line should remain in place or be removed before treatment.
• infusion site be infiltrated with an antidote prescribed after
assessment by the physician and application of warm or cold
compresses, depending on the medication infusing.
• extremity should not be used for further cannula
placement.
• Thorough neurovascular assessments of the affected
extremity must be performed frequently
103. Prevention
• Review institution’s IV policy and procedures and
incompatibility charts and checking with the pharmacist
before administering any IV medication, whether given
peripherally or centrally
• to determine incompatibilities and vesicant potential.
• Careful, frequent monitoring of the IV site
• avoid insertion of IV devices in areas of flexion
104. Prevention
• secure the IV line
• use smallest catheter possible that accommodates the
vein
• when vesicant medication is administered by IV push, it
should be given through a side port of an infusing IV
solution to dilute the medication and decrease severity of
tissue damage if extravasation occurs
107. S/S
• reddened, warm area around the insertion site or along
the path of the vein
• pain or tenderness at the site or along the vein, and
swelling.
• incidence of phlebitis increases with
• Length of time the IV line is in place
• composition of the fluid or medication infused (especially its pH and
tonicity)
• size and site of the cannula inserted
• ineffective filtration
• improper anchoring of the line
• introduction of microorganisms at the time of insertion.
110. Thrombophlebitis- S/S
• Localized pain
• redness, warmth, and swelling around the insertion site or
along the path of the vein
• immobility of the extremity because of discomfort
• swelling, sluggish flow rate
• Fever
• Malaise
• Leukocytosis
111. Management
• D/C IV infusion
• 1st: cold compress to decrease the flow of blood and
increase platelet aggregation
• followed by a warm compress
• Elevate extremity
• Restart line in the opposite extremity
• If (+) patient has signs and symptoms of thrombophlebitis,
the IV line should not be flushed
• (although flushing may be indicated in the absence of phlebitis to
ensure cannula patency and to prevent mixing incompatible
medications and solutions).
112. Prevention
• Avoid trauma to vein at time the IV is inserted,
• Observe site every hour
• Check medication additives for compatibility
114. Hematoma
• Hematoma results when blood leaks into tissues
surrounding the IV insertion site.
• Leakage can result from
• perforation of opposite vein wall during venipuncture
• Needle slipping out of vein
• insufficient pressure applied to the site after removing the needle or
cannula.
116. Management
• Remove needle or cannula and apply pressure with a
sterile dressing
• Apply ice for 24 hours to
• site to avoid extension of the hematoma
• then warm compress to increase absorption of blood;
• assessing the site
• Restart the line in the other extremity if indicated.
117. Prevention
• carefully insert needle
• use diligent care when a patient has a bleeding disorder,
takes anticoagulant medication, or has advanced liver
disease
118. 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 solution
administrations.
• The signs are decreased flow rate and blood backflow
into the IV tubing.
119. 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
120. 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.
125. Fluid Overload
• Overloading the circulatory system with excessive IV
fluids causes increased blood pressure and central
venous pressure.
126. Fluid Overload – S/S
• moist crackles on auscultation of the lungs
• Edema
• weight gain
• Dyspnea
• respirations : shallow and increased rate.
127. Fluid Overload – causes
• rapid infusion of an IV solution or hepatic, cardiac, or
renal 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.
128. Management
• Decrease IV rate
• Monitor VS frequently
• Assess breath sounds
• Place patient in high Fowler’s position
• Contact physician immediately.
129. Prevention
• Use infusion pump for infusions
• carefully monitoring all infusions.
• Complications of circulatory overload
• include heart failure and pulmonary edema.
130. Air Embolism
• risk of air embolism is rare but ever-present.
• most often associated with cannulation of central veins.
131. Air Embolism
• dyspnea
• Cyanosis
• hypotension
• weak, rapid pulse
• loss of consciousness
• chest, shoulder, and low back pain.
132. Management
• Immediately clamp the cannula
• Place patient on the left side in Trendelenburg position,
• Assess VS and breath sounds
• Administer oxygen.
133. Prevention
• Use a Luer-Lock adapter on all lines
• filling all tubing completely with solution
• Use an air detection alarm on an IV pump.
134. Septicemia and Other Infection
• Pyrogenic substances in either the infusion solution or the
IV administration set can induce a febrile reaction and
septicemia.
135. S/s
• abrupt temperature elevation shortly after the infusion is
started
• Backache
• Headache
• increased pulse and respiratory rate
• Nausea and vomiting
• Diarrhea
• chills and shaking
• general malaise.
• In severe septicemia:
• vascular collapse and septic shock
136. Causes of septicemia
• contamination of the IV product or a break in aseptic
technique
• especially in immunocompromised patients.
137. Management
• Treatment is symptomatic
• culturing of the IV cannula, tubing, or solution if suspect
• establishing a new IV site for medication or fluid
administration.
138. • Infection ranges in severity from local involvement of the
insertion 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.
139. Prevention
• Careful hand hygiene before every contact with any part
of the infusion system or patient
• Examine the IV containers for cracks, leaks, or
cloudiness, which may indicate a contaminated solution
• Use strict aseptic technique
140. Prevention
• Firmly anchor the IV cannula to prevent to-and-fro
motion
• 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% povidone–iodine, alcohol, or chlorhexidine,
used alone or in combination.
141. Prevention
• Remove the IV cannula at the first sign of local
inflammation, contamination, or complication
• Replace the peripheral IV cannula every 48 to 72 hours,
or as indicated
• Replace the IV cannula inserted during emergency
conditions
(with questionable asepsis) as soon as possible
142. Prevention
• Use a 0.2-micron air-eliminating and bacteria/particulate
retentive 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
144. Prevention
• Replace solution bag and administration set in
accordance 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 administration
sets every 72 hours, or immediately if contamination is
suspected
• Change primary intermittent administration sets every 24
hours, or immediately if contamination is suspected
