Injections By: Drx. Pankaj Dwivedi Faculty OPP College www.oppcollege.com 1
What is an injection? Injections are sterile solutions, emulsions or suspensions. They are prepared by dissolving, emulsifying or suspending an active ingredient and any other substances in water for injection. Injecting is the act of giving medication by use of syringe and needle to obtain the desired therapeutic effect taking into account the patients safety and comfort www.oppcollege.com 2
Types of Injections Parenteral medication: administration of a medication by injection into bodytissues Subcutaneous (SC) – into tissue below dermis ofskin Intramuscular (IM) – into the bodymuscle Intravenous (IV) – into avein Intradermal (ID) – into the dermis just under the epidermis www.oppcollege.com 3
Purposes of Injection To get rapid and systematic effect of the drug. To provide the needed effect even when the client is unconscious. Assure that the total dosage will be administered and the same will be absorbed for the systemic actions of the drug. To obtain a local effect at the sight of injection e.g. xylocaine, tuberculin test. To restore blood volume by replacing the fluids. To give nourishment when it can’t be taken by mouth. www.oppcollege.com 4
Syringes Three main parts: Barrel – chamber that holds themedication Plunger – part within the barrel thatmoves back and forth to withdraw and instill medication Tip – part that the needle is attached to www.oppcollege.com 5

Which is which needle? The correct needle is the key to delivering the drug to the correct area for the maximum effect with the least amount of discomfort The colour at the top of the needle reflects its size the higher the number the smaller the lumen(bore). www.oppcollege.com 7

INTRADERMAL INJECTIONS www.oppcollege.com 24
INTRADERMAL INJECTION It is the introduction via needle of tiny amounts of fluid into layers of skin. It provides a local, rather than systemic effect. Syringe used is 1ml tuberculin syringe because ofa very small amount of drug needed. Needle used is a short (1/4 to 5/8 inch), fine gauge (g25-27). Indications: For diagnostic purposes (allergies and sensitivities to drugs) For administering tuberculin testing www.oppcollege.com 25
INTRADERMAL INJECTION Intradermal literally means “between the skin layers” and injection is administered just under the epidermis . Syringe is positioned at15 ˚ angle . Small volumes, usually 0.01 to 0.05ml, are injected because of the small tissue space. www.oppcollege.com 26
INTRADERMAL INJECTION Most commonly used site: Inner surface of the forearm Subscapular region of the back can be used as wel as d . eltoid region www.oppcollege.com 27
INTRADERMAL INJECTION REMEMBER: Mixture of drug and water for skin testing: 0.9cc of distilled water/sterile water and 0.1cc of the drug. Inject the solution intradermally and just enough to form a wheal. Encircle the site correctly and write the time when to check the injection site to determine reaction to the drug. Check the site after 30 minutes for signs of reaction. If negative, document it as ANST(After Negative Skin test)(-); if positive, ANST (+) www.oppcollege.com 28
INTRADERMAL INJECTION REMEMBER : A pos i tive result may b e m an ifested b y an y o f the following: R e dd e n i n g o f the s it e acc o mpa n i e d w i th marked elevation Increase in circumference of the wheal Presence of itchiness on the site www.oppcollege.com 29
PRO C ED U RE Prepare all the equipment needed: 1cc syringe, disposable needle (aspirating needle), sterile water, drug to be tested, wet and dry cotton balls and ballpen. Wash hands and observe appropriate infection control measures. Introduce yourself and verify the client’s identity. Explain to the client what you are going to do, why it is necessary and how the client can cooperate. Prepare needed materials aseptically. Check the label of the drug three times. www.oppcollege.com 30
PRO C ED U RE Pre p a re th e medicat io n to b e used for skin tes t i n g (e.g ampule or vial) Aspirate 0.9cc of distilled water/sterile water and 0.1cc of the drug using the tuberculin syringe with the aspirating needle. Mix the drug and the distilled water in the syringe. Replace the aspirating needle with g25 needle. Expel excess air. P l ace the syringe o n the t r ay t o gether w i t h the w e t and dry cotton balls. www.oppcollege.com 31
PRO C ED U RE Confirm again patient’s identity. Locate the appropriate site for skin testing. C l eanse the med i a l surf ace o f th e for earm b y u s i ng firm, circular motion from inner to outer portion. Allow the skin to dry before injecting the drug. Place hand in non-dominant hand of the patient. Remove needle cap and holds syringe at 15 degree angle from skin with bevel up. Stret ch the skin an d t e l l the patient that he/she wil l feel a prick as needle is inserted. www.oppcollege.com 32
PRO C ED U RE Inject the solution intradermally and just enough to form a wheal. Remove the needle quickly but gently at the same angle used for injection. Wipe with dry cotton ball but do not press the injection site. Encircle the site correctly and write the time when to check the injection site to determine reaction to the drug. Check the site after 30 minutes. www.oppcollege.com 33

C l ea nse the site us i n g circ u l a r mo t i o n fr o m i n ne r to outer portion and allow it to dry. Place a swab between fingers of non-dominant hand.
