Those who want to know how to inject injections need to imagine which part of the body is best for injection. An intramuscular injection is more often done in one of the buttocks, less often - in the anterior part of the thigh. The latter option is usually practiced if a person makes intramuscular injections on his own. However, an injection in the thigh is much more painful than in the buttock. Since injecting injections yourself is not very convenient and hematomas often form at the injection site in the thigh, it is better to resort to outside help if possible.
The buttock is mentally divided into four parts crosswise, horizontally and vertically. Injection is performed only in the upper outer quadrant, approximately in its middle. This requirement is due to the fact that when injected into another part of the buttock, the sciatic nerve may be affected . Gross damage leads to its inflammation - neuritis, accompanied by severe pain. In the future, loss of sensation in the leg and even muscle atrophy may develop. Therefore, those who want to understand how to give an injection intramuscularly should definitely follow this important rule.
Hands are wiped with a cotton swab with alcohol or antiseptic wipes, the ampoule is treated in the same way. The ampoule is shaken so that there is no medicine left at its tip. Then they take a cotton swab moistened with alcohol or an antiseptic napkin and break off its neck. Most often on the ampoule there is a special marking (line or dot), showing in which place you need to do this. Otherwise, it must be filed with a special file.
The disposable syringe is removed from the package by tearing it from the side of the piston so as not to touch the needle with your hands. The syringe is inserted into the needle without touching it. Holding the needle with the fingers at the base, remove the cap from it. The solution is collected in a syringe, pulling the piston. Turning over the syringe and smoothly moving the piston, air is removed from it. The syringe is laid aside: now you need to treat the injection site with alcohol. Previously, the needle must be covered with a cap to protect it from contamination.
If the medicine is in the form of a powder, it must first be diluted with novocaine or water for injection (according to the instructions and doctor's prescription). Novocaine is naturally preferable, but you should be sure that the patient is not allergic to this drug. To prepare the solution, you will need one syringe and two needles. Water or novocaine is drawn into a syringe as described above. The lid of the vial with a dry preparation is wiped with alcohol and liquid is injected through the syringe through it. After this, the medicine is shaken gently until completely diluted and collected in a syringe. Before making an injection, a new, sterile needle is put on it.
Injections are more convenient when the patient is lying on his stomach. However, in extreme cases, you can give an injection to a standing person. The injection site is wiped with a disinfectant solution. Take a syringe and with a clear, but not coarse, fast movement, insert the needle perpendicular to the surface of the skin (its slow introduction is much more unpleasant for the patient). An important point that you need to pay attention to those who want to know how to prick correctly: the needle is not completely inserted, but only ¾ of its length. This is due to the fact that if it breaks during the injection (for example, due to sudden movements of the patient), removing it otherwise will be problematic.
The drug is administered slowly to avoid tissue damage. If injections are made quickly, painful seals form in their place, which can resolve long enough - this should be paid attention to those who want to understand how to inject injections. After drug administration, the skin at the base of the needle is slightly held with a sterile cloth and the syringe is removed with a slight movement.
The injection site is lightly pressed with a cotton swab with alcohol and held for a while until the blood coagulates. Important: if a blood vessel was injured during the injection, the injection site should be tightly pressed and the tampon held on it for at least five minutes, then ice must be applied, otherwise bruises may form.
Thus, everyone can learn to do intramuscular injections - there are no special difficulties in this process. Before giving an injection to a person, it is worth practicing to inject a syringe on a pillow or soft toy - this will protect the patient from excessive pain. In addition, those wishing to learn how to inject injections should understand: the rules for injecting various drugs can have their own characteristics. So, oil solutions are introduced pre-heated. After the needle is inserted into the buttock, you should make sure that the blood vessel is not touched - this is important for oil solutions! To do this, slightly pull the piston toward you: if blood does not enter the syringe, the drug can be administered.
