How to make an injection?
Only sterile disposable equipment is used to perform the injection, such as: needle and syringe, disinfectant, gloves, gauze. You also need a container for used medical supplies. The person performing the injection should also have an anti-shock kit - in case the patient has an unexpected allergic reaction to the administered drug. Before starting the injection, the patient should be interviewed to make sure that there are no contraindications to the administration of a particular medicine. Then you need to check the condition of the ampoule with the drug. The professional will also take care of the patient's comfort, e.g. suggest a comfortable position for him and inform him about the course of the procedure. When administering the injection, observe the rules of asepsis - wash and disinfect your hands, put on gloves and disinfect the injection site.
For an intramuscular injection, you can use, for example, the brachial muscle, lateral or transverse thigh muscle, but most often intramuscular injections are made into the gluteal muscle, which, due to its size and blood supply, ensures optimal distribution and absorption of the administered substance. Larger muscle also allows for the application of more drug. No more than 5 ml of the substance should be administered intramuscularly, larger volumes should be administered intravenously. An injection in the buttock is made in the upper outer quarter of the muscle (to bypass the nerves, Picture 1) by inserting the needle perpendicular to the buttock (Picture 2). An aspiration test is then performed to make sure that the needle missed a blood vessel. Slowly depressing the syringe plunger minimizes the patient's pain; children can use ointments or patches to numb the injection site. After administering all the liquid, it is worth waiting a while before removing the needle, this reduces the leakage of the drug from the injection site. Due to the limited visibility and range of the puncture site, self-intramuscular injection is very difficult even for a professional. Improper puncture may result in nerve damage or hemorrhage. For an injection into the buttock, it is best to place the patient in a supine position with the leg bent at the knee joint.
