Sometimes a person becomes a home nurse or nurse if necessary. For example, you have to perform various kinds of injections at home. Then, in particular, it may be necessary to perform a subcutaneous injection. How to do it right, this article will tell.
How to inject injections subcutaneously, they teach in all kinds of courses, but you can master this simple technique on your own, both for women and men. With a fairly calm and accurate approach, problems should not arise at all.
Subcutaneous injections are made for the reason that due to the good blood supply to the subcutaneous fat layer, drugs are better and faster absorbed here. Accordingly, the effect of drugs introduced into the body is thus more effective than when administered through the mouth. Up to two milliliters of solutions are usually administered subcutaneously.
Subcutaneous injections are made with the smallest diameter needle. Obviously noticeable large vessels should be avoided. The most suitable places for subcutaneous injection are the external shoulder surface, the external femoral surface. Sometimes injections subcutaneously are performed in the subscapular space or the lower part of the axillary region. In these places, it is easiest to capture the skin in a crease, and the risk of damage to large blood vessels is minimal.
Subcutaneous administration of the drug provides a more prolonged effect of the drugs than with intravenous injection. An exception is cases of insufficient peripheral circulation.
Subcutaneous Injection Technique
First of all, wash your hands well with soap and wear surgical gloves. The following actions are performed:
- You should choose the right syringe for injection. Subcutaneous injections are usually performed with a two-milliliter syringe.
- The ampoule with the drug is also processed with alcohol, after which a special nail file that comes with the medicine is applied to make a file and the tip of the ampoule breaks off.
- If the medicine is in a vial with a metal cap and a rubber stopper, the upper part of the cap should be removed, the surface of the rubber stopper treated with alcohol and pierced with a needle. If the drug is in powder, then it should be dissolved through the same needle.
- The medicine is selected into the syringe by pulling the piston.
- After the medicine has completely got into the syringe, it is necessary to remove excess air by slowly and carefully pressing the piston with a finger. Keep pressing until a trickle of solution appears from the needle. In this case, the syringe is held upward by the needle, and to collect air bubbles to the outlet, you need to gently tap the syringe with your finger.
- The estimated place where the injections will be performed subcutaneously is treated with alcohol. First, a large area is treated with a cotton swab, and then the injection site is directly treated with another swab moistened with alcohol.
- The skin should be captured in a fairly thick fold and pulled up.
- Quickly, but carefully, the needle is pierced into the base of the resulting skin fold and inserted into the fat layer.
- By slowly pressing the plunger of the syringe, the drug is squeezed out under the skin.
- In the same quick and sharp movement, the needle is removed from under the patient’s skin, and the injection site is slightly massaged and again treated with alcohol.
Sometimes subcutaneous injections are performed in the abdomen. To make the injection correctly, you should mentally draw on the patient’s stomach a figure eight, having a center in the navel.
In one of the rings of this figure eight are injected. All other actions are performed in almost the same way as in the example described above. It should be noted only that the skin in this place is very delicate, and all actions should be performed as carefully as possible to avoid bruising. The G8 ring changes with each subsequent subcutaneous injection into the abdomen.
