Wash your hands thoroughly. This is the best way to prevent infection. 2. Assemble your equipment: medication • May be a multidose vial of liquid or may be a vial with powder that requires “reconstitution.” Follow the manufac- turer’s instructions as to what and how much diluent to use. The diluent is usually saline (a mixture of salt water) or sterile water. syringe and needle: Depending on the amount of medication to be given and the size of the child or adult: • 0.5 cc,1.0 cc, or 2 cc with 27-gauge A subcutaneous injection into the fatty layer of needle (5/8 of an inch long) tissue (pinched up to give the injection) under the • 3 cc luer lock syringe—used when skin. solution is more than 1 cc • 25-gauge needle (5/8 of an inch long Why are subcutaneous injections or 27-gauge needle (5/8 of an inch long) given? • 0.3 mL insulin syringes with 28-gauge These injections are given because there is needles (1/2 inch long ) are available little blood flow to fatty tissue, and the injected for those who are visually impaired or medication is generally absorbed more slowly, for those who need very small doses sometimes over 24 hours.

3. Locating injection sites Subcutaneous injections can be given in the arms, legs, or abdomen. Your nurse or doctor will help you select the best sites to administer your medication. 1. To locate injection sites on the arms, fold one arm across the chest. Place your hand on the shoulder and draw an imaginary line below your hand. Place another hand on the elbow. Draw an imaginary line down the outer side of the arm and down the center front of the arm, starting at the elbow. The area inside these imaginary lines is where injections are given. (If you are injecting yourself, imagine the hand placement.) Injection sites on the side of the Injection sites on the back of the arm. arm. 2. To locate injection sites on the thighs, sit down, place your hand above the knee, and draw an imaginary line above it. Place your hand at the uppermost part of the thigh and draw an imaginary line below your hand. Draw an imaginary line down the outer side of the leg and down the center front of the leg. The area within these imaginary lines is where injections may be given. Injection sites on the thighs. 3 Patient Information Publications Giving a Subcutaneous Injection
4. 3. To locate injection sites on the abdomen, place your hands on the lower ribs and draw an imagi- nary line below them. Use this area below your hands for injections, as far around as you can pinch up fatty tissue. Do not use a 1-inch area around the navel. Rotating injection sites It is extremely important to rotate sites to keep the skin healthy. Repeated injections in the same spot can cause scarring and hardening of fatty tissue that will interfere with absorption of medication. Each injection should be about 1 inch apart. Each injection site can be measured with a small dot Band-Aid, providing the patient is not sensitive to the adhesive. Start injections at the highest Injection sites on the abdomen point of the area and continue down toward the point farthest away from the body (for example, upper arm down toward elbow). It is preferable to use all sites available on one body part (arm or leg) before moving on to another. However, some parents find that children are more accepting of injections if they are rotated from one body part to another (arm, leg, arm, leg). Avoid giving injections in areas that are burned, red- dened, inflamed, swollen, or damaged by prior injections. 3. Grasp the skin between the thumb and Preparing the skin index finger.

Gently pull back on the plunger and Safe needle disposal check for the appearance of blood in the syringe. Please refer to the Clinical Center pamphlet Note: Not all injections require you to “Handling Sharp Objects Safely at Home.” check for blood. Before you are dis- charged, your nurse will let you know if you need to do this. If you do not, then skip down to step 10. Medication 9. If blood appears, remove the needle, discard it, and start over. Blood in the syringe means that you may be in a blood vessel, Dose so discard the syringe with medication. Do not inject medication into a blood vessel: the medication is absorbed too Schedule rapidly if it is injected there. 10. If no blood appears, inject the medication at a slow, steady rate. Medication should Primary Nurse be injected within 5 seconds. Phone 11. As the needle is pulled out of the skin, gently press a 2x2 gauze onto the needle Physician insertion site. Pressure over the site while removing the needle prevents skin from pulling back, which may be uncomfortable. Phone The gauze also helps seal the punctured tissue and prevents leakage. 12. If instructed to do so, press or rub the site for a few seconds. 13. It is not serious if you notice blood at the site after the needle is removed. You may have nicked a surface blood vessel when you injected, and blood is following the needle track out to the surface.
