Intravenous
Administration - IV Injection or IV Therapy
Intravenous injection or infusion method of the parenteral
route, medication sent directly into the vein using a needle or tube. Intravenous injection is abbreviated as IV.
Intravenous (IV) injection involves
inserting a needle into the vein, allowing the substance directly delivers to the bloodstream.
IV or intravenous therapy is a route to give medicine,
fluids, nutrition, or blood directly into the bloodstream through a vein, and is also used for taking blood products sampling of blood in the blood
collection tube.

of Blood Collection and what are the complications?
IV route allows medication
absorbed more rapidly and avoids the first-pass metabolism.
IV therapy
uses a type of tiny plastic tubing called a cannula that inset into the
vein, a needle, and plastic tubing connects to a fluid bag.
Angles of Intravenous injection
IV injection is given at a 25-degree angle.

of intramuscular injection, subcutaneous Injection, and intradermal
Injection?
Site of IV Administration
IV administration placed; vein in –
1. Wrist
2. Elbow

Medical Use of IV Therapy
1. IV Therapy for
medications
2. IV Therapy for
fluids
3. IV Therapy for
nutrition
4. IV Therapy for
blood transfusions; through blood

Equipment Used in IV Administration
Equipment used for administration of IV therapy-
1. IV Catheter tube Uses as Standard IV
Administration
IV catheter tubes are-
a. Intravenous Cannula
b. IV Butterfly Catheters
2. Standard IV Catheter
Standard IV catheters include-
1. IV push
2. IV infusion
The way of IV infusion therapy-
a. Pump infusion
b. Syringe pump
c. Drip infusion
1. IV Catheter
A thin plastic tube called an IV catheter is
inserted into your vein. IV catheter used as standard IV administration.
The needle is usually inserted into a vein in the site of the wrist,
elbow, or the back of the hand.
IV catheter is introduced into the vein by a needle. IV
catheter allows giving multiple safe doses of medication without needing to
prick with a needle each time.
A. Intravenous Cannula
Intravenous (IV) cannulation is a technique in which a
cannula is placed inside a vein to provide venous access, it allows
administration of fluids, medications, parenteral nutrition, chemotherapy, and
blood products sampling of blood.
How many types of
cannula are there? Know IV cannula sizes
and their uses.
B. IV Butterfly Catheters
IV Butterfly Catheters or Scalp Vein Sets or butterfly
needle or winged infusion set is
a device used to insert a vein for giving medications or drawing blood.
IV butterfly needle is a very thin hypodermic needle; it has
two flexible wings; flexible transparent tubing, and a connector.
The connector can be attached to tubing from an infusion
pump or bags of IV to deliver medications or fluids to the bloodstream or
attach to a vacuum tube or collection bag to draw for blood specimen
collection.
Through a connector, medications can also be delivered via a
syringe.
2. Standard IV Catheter
Standard IV the catheter used to two kinds of IV medication
administration -
A. IV push
B. IV infusion
A. IV Push
Intravenous or push IV therapy is the rapid administration
of the injection.
A syringe is connected to a catheter and quickly delivers
the medication into the bloodstream.
B. IV Infusion
IV infusion is a controlled administration of medication
into a patient’s bloodstream over time.
These devices are used for medication administration-
1. Pump infusion
2. Syringe pump
3. Drip infusion
1. Pump Infusion
An infusion pump is a medical device that delivers fluids,
such as nutrients and medications, into a patient's body in controlled amounts.
The infusion pump is attached to the patient's IV line.
2. Syringe Pump
A syringe pump is a
small infusion device that is used to gradually administer
specific amounts of fluids.
Syringe pumps devices are used to gradually administer
small amounts of medication or fluid to a patient.
Syringe pumps work as pushing out fluid via a syringe to send the medication into IV tubing in a predetermined volume that delivers fluids, such as
nutrients and medications, into a patient's body in controlled amounts.
3. Drip Infusion
Drip infusion therapy involves IV tubing set and solution bag that contains
fluids. IV solution drip delivers fluids from solution bag and go through a
tube and into the catheter and deliver into patient’s bloodstream.
Drugs Typically Administered by IV Therapy
Antibiotics and pain-relieving medication are common, given
through IV administration.
1. Antibiotics Drugs
Drugs like Gentamicin, Vancomycin (treat bacterial infection).
2. Chemotherapy
Drugs
For example, Doxorubicin, Cisplatin (slow or stop the growth
of cancer cells).
3. Pain Relieving Medications
Drugs are
hydromorphone, morphine (pen control).
4. Drugs used
to Treat Low Blood Pressure (Hypotension)
Drugs are dopamine, epinephrine, norepinephrine, and
dobutamine.
Complications of IV Administration
Generally, IV medication is safe, but any incidence leads to
mild to severe effects. There is some complication of IV Administration-
1. Risk of Infection
To prevent infection, use an aseptic technique.
2. Hematoma
Leakage of blood from the vessel into the surrounding
soft tissue.
3. Damage of Blood Vessel and injection site
4. Infiltration
Medication leaks into the surrounding tissue.
4. Air Embolism
5. Blood Clots
6. Phlebitis
Inflammation of the
vein
7. Thrombophlebitis
Inflammation of a vein is caused by a blood clot.
