3. Injection
Injection
It is an infusion method of putting fluid into the body,
usually with a syringe for the material to be administered
into the body.
Syringe is a device made of a hollow tube and a needle
that is used to force fluids into or take fluids out of the
body.
4. The length of a needle is measured in inches from the juncture
of the hub and the shaft to the tip of the point.
The gauge of a needle, used to designate the size of the lumen,
ranges from 27 (the finest) to 13 (the largest).
When looking at a needle package, the first number is the gauge
or diameter of the needle and the second number is the length.
As the gauge number becomes larger, the size of the needle
becomes smaller.
6. Intradermal Injection
Intradermal Injection
It is an injection given into the dermal layer of the skin for some
purposes :
– Local Anesthesia
– Diagnostic Tests
– Immunizations (BCG vaccine)
Needle used is a short (3/8 inch) length, gauge (25-27G).
Small volumes, usually 0.01 to 0.05ml, are injected because of
the small tissue space.
Syringe is positioned at 10˚-15˚ angle.
Create small bubble like.
8. Check the 5 Right then :
1.Wash hand and Take equipment to the patient's side.
2.Explain procedure to patient.
3.Locate the site of injection, and Cleanse the skin with a spirit
swab, allow the area to dry.

− Heparin Injections
− Many Vaccines (MMR)
Needle used is (3/8 to 1 inch) length, gauge (24-27g)
(But Insulin needle=28-30g.)
No more than 1.5 mL should be injected to avoid
pressure on sensory nerves causing pain and discomfort.
Inject the needle at an angle of 45˚ or 90˚, depending on
the amount and thickness of the tissue and the length of the
needle.
11. Check the 5 Right then :
1.Wash hand and Take equipment to the patient's side.
2.Explain procedure to patient.
3.Locate the site of injection, and Cleanse the skin with a spirit swab,
allow the area to dry.
4.Remove needle cap and holds syringe at 45˚angle, then Inject the
needle .
5.Draw back the plunger to check you are or aren't in the blood
vessel (Blood return should not be seen) then inject the solution.
6.Remove the needle quickly but gently at the same angle used for
injection and massage the area with alcohol swab .
