Safe injection is the key for accuracy and effectiveness. There are different ways to administer injections. Each technique serves its own purpose for less bruising, transmission, and relief. Learn the different injection techniques for a safe and injection area.

Types of Injections

The type of injection you give depends on the specific area of the body where it is to be administered, the type of medication, and the dosage. A couple common types of injections are: 1. Subcutaneous (SQ) A subcutaneous injection is one that is delivered into fatty areas of skin. The injection goes in between the muscle and skin. SQ injections go into the fatty area. These injections are ideal for medicines that can be delivered in small amounts, only 1 to 2 mls. It is also ideal when a medication requires slow absorption for maximum effectiveness. 2. Intravenous These types of injections are given directly into the veins. 3. Intramuscular Use only the intramuscular route when you want immediate muscle use is required. For this, use only a blue or green needle.   For this article, we will discuss how to do subcutaneous and intramuscular injections.  

Tips for Injection Technique

  • Use an orange needle for subcutaneous injections
  • Pinch to raise the skin from the muscle
  • Inject into the subcutaneous area at a 45-degree or 90-degree angle
  • Use the intramuscular technique only on the deltoid, gluteals, vastus literalis, and rectus femoris.
  • Use a 25-guage needle for intramuscular injections.
  • Remove any air in the syringe by tapping it up pushing the plunger.
  • Clean your hands and your injection site thoroughly.
  • Inject slowly.
  • Pull out just as quickly as you injected the needle into the area.

Injection Techniques

Before you begin, inspect the vial to ensure you are using the correct one. You will need alcohol pads, a brand new, hand sanitizer, sterile syringe, and latex gloves.
  • Abdomen
To give an injection in the abdomen, you need to remember to alternate sides each time. If you give an injection in the left side first, the next one should go in the right side. When giving an injection in the abdomen, stay away from the bones. The injection should go in the waist area, above the hips. Do not inject near bone or the belly button.
  • Arm
The limbs are common areas for subcutaneous and intravenous injections.  Give the injection in the fatty part of the arm. The shoulder area is a good spot because it is hard and it can be hidden. The risk for bruising in lower in this area. To give an injection in the arm, pinch a large area of skin together - about two inches wide -  and deliver the injection. Another good area to do injections is on the outside of the arm, between the elbow and the shoulder. It is not recommended that you give an injection in the forearm.
  • Thigh
The part of leg between the knee and the hip is an excellent place for injections because of the surface area and muscle. Just as you would when giving an injection in the arm, pinch a 2-inch area of the thigh and insert the needle. You will want to use a 25-guage, 5/8 needle. Insert into the thigh and hold the needle at a 90-degree angle. Use the outer area of the thigh only. Do not hit the IT band. Stay in the muscle.
  • Lower back
Injections in the lower back are easier because of the surface area, muscle, and the ability to hide injection sites. Stick to the lower back, and stay above the hips. Again, avoid bone. You MUST stay away from the spine. When you deliver injections to the lower back, do so off to the side, closer the hips. If you prefer injections in the torso area, you can combine lower back and abdominal injections to reduce bruising, sensitivity and damage to the area. Rotate. If you do an injection on left switch to the right side the next time, and for the third and fourth injections, use the abdomen. Go in a circle around the torso, injecting into a new side each time. To do a back injection, pinch the skin and inject the syringe into the middle of the area.
  • Gluteal Muscle
Use the intramuscular injection technique for the gluteal area. Always inject in the most upper and outer area of the glutes. Inject the needle in at a 90-degree angle. Stabilize the syringe with your opposite hand.
