Transcript Injection

Injection
Injection is a method of putting liquid into
the body with a hollow needle and a
syringe which is pierced through the skin
to a sufficient depth for the material to be
forced into the body.
An injection follows a parenteral
route of administration, that is,
its effect is not necessarily local
to the area in which the injection
is administered; it is systemic.
There are several types of
injections including:
Intradermal:ID
Subcutaneous:SC
Intramuscular:IM
intravenous:IV
Some injection method else:
intra-arterial (into an artery), e.g. vasodilator drugs in the treatment of
vasospasm and thrombolytic drugs for treatment of embolism.
Intracardiac (into the heart), e.g. adrenaline during cardiopulmonary
resuscitation
Intraosseous infusion (into the bone intravenous access because the
bone marrow drains directly into the venous system. This route is
occasionally used for drugs and fluids in emergency medicine and
paediatrics when intravenous access is difficult.
Intrathecal (into the spinal canal) is most commonly used for spinal
anesthesia and chemotherapy
Intraperitoneal, (infusion or injection into the peritoneum) e.g. peritoneal
dialysis is predominantly used in veterinary medicine and animal testing
for the administration of systemic drugs and fluids due to the ease of
administration compared with other parenteral methods
