IV Cannula vs IV Catheter: Understanding the Differences
In the medical field, intravenous (IV) access is a fundamental procedure
used for administering fluids, medications, and blood products directly into
the bloodstream. Two common devices used for this purpose are the IV cannula
and the IV catheter. While these terms are often used interchangeably, they
refer to different types of medical devices, each with its unique
characteristics and applications. Understanding these differences is crucial
for medical professionals to ensure appropriate use in patient care.
IV Cannula
An IV cannula,
often simply referred to as a cannula, is a small, flexible tube that is
inserted into a vein to provide access for intravenous therapy. Typically made
of plastic, an IV cannula consists of a hollow needle with a thin, flexible
tube that remains in the vein once the needle is withdrawn. The primary
function of an IV cannula is to serve as a conduit for the infusion of fluids
and medications.
IV cannulas are categorized by size, which is determined by the gauge of the
needle. Sizes range from 14 gauge (large) to 24 gauge (small), with smaller
gauges being used for patients with smaller veins or for less viscous fluids.
The choice of size depends on the specific needs of the patient and the type of
therapy being administered.
IV Catheter
On the other hand, an IV catheter is a broader term that encompasses various
types of devices used for intravenous access. It refers to any tube or catheter
inserted into a vein to administer fluids or medications. Unlike an IV cannula,
which specifically denotes a device with a needle that is withdrawn, an IV
catheter may include devices such as central lines, peripheral lines, and other
specialized access tools.
IV catheters can be categorized based on their insertion site and purpose.
For instance, peripheral IV catheters are inserted into veins in the arms or
hands and are typically used for short-term therapy. Central venous catheters,
inserted into larger veins like the jugular or subclavian veins, are used for
long-term treatments or for administering medications that require central
circulation.
Key Differences
1. Design
and Insertion: An I.V. cannula
is designed with a needle that is removed once the device is in place,
leaving a thin, flexible tube for infusion. An IV catheter, in contrast, may
include a broader range of devices, including those that remain in place with
various anchoring systems.
2. Application:
IV cannulas are generally used for short-term access and are commonly found in
emergency or routine medical procedures. IV catheters, due to their variety,
can be used for both short-term and long-term access, depending on the specific
needs of the treatment.
3. Types
and Sizes: While IV cannulas are categorized mainly by gauge size, IV
catheters include a wider range of designs and insertion sites. This makes IV
catheters more versatile for different medical needs, from simple infusions to
complex central venous access.
4. Duration
of Use: IV cannulas are usually used for short durations, such as
during a hospital stay or for specific procedures. IV catheters, especially
central lines, can be used for extended periods, such as for ongoing treatments
in chronic conditions.
