I will tell you about injections, better known to the average person, as an “injection into a vein”. Intravenous injection is the injection of a drug directly into the bloodstream (bloodstream). I myself did them well at one time, when I was practicing from a medical school in an emergency hospital. I can do it today and I believe that any health care provider should not only know how to make intravenous injections, but also technically correctly and efficiently perform them.
Recently I heard a woman telling me that doctors don’t get into her veins the first time. At the same time, she questions the qualifications of nurses. The fact is that such a phenomenon does occur.
Case in the handling room
It was in one district clinic. The name of the settlement does not matter, as this could happen anywhere. Unfortunately, I personally had to deal with such cases when intravenous injections were made, the technique of which left much to be desired.
So, in the district clinic, the patient was prescribed an intravenous injection of glucose. Omitting the details, it is worth noting only the fact that the man got his entire forearm pierced, and then his hands. An injection into a vein was never performed until specialists from the intensive care unit arrived. This should not be, of course. Imagine that once in a similar situation I injected myself into the manipulation room myself. True, I had to show a diploma of a medical school.
In fact, there is nothing complicated, and intravenous injection is performed with sufficient preparation quite easily. In the above story, an intern tried to perform an injection into a vein. I remember how medical school students were not allowed to see us until we had enough practice on each other. Perhaps because they trained us, as military paramedics, for the army, any student in our group could make any injection with almost closed eyes.
Types of injections
- Intramuscular This is perhaps the most common and simple.
- Intradermal. For the purpose of diagnosis (allergic tests), prevention (vaccinations).
- Subcutaneous
- Intravenous injection. I will describe the execution technique below.
- Intraarterial
- Intraosseous.
Intravenous Injection Technique
- First you need to seat or lay the patient. If necessary, the person should be reassured.
- It is necessary to put a special roller under its elbow bend.
- The imposition of a venous tourniquet is made from bottom to top above the fold. It is not necessary to impose on a naked body and it is not necessary to tighten a plait strongly.
- Let the patient “work with his fist” (squeeze and unclench his fist several times), and then squeeze it and not unclench until the end of the procedure.
- The place where the intravenous injection will be performed must be treated with alcohol using a cotton ball moistened in it. In this case, the first cotton ball needs to be treated with a larger area around the proposed injection site. The second ball must be directly processed directly to the injection site into a vein (puncture). The movement is performed from the bottom up, as a result, the vein becomes more accessible due to the flow of blood. Another ball moistened with alcohol is taken under the little finger of a syringe-free hand.
- The syringe is taken in the hand, the cap is removed from the needle. It is necessary to lightly press the piston to bleed air from the syringe. It should be kept by guiding the needle with the cut up. The cannula of the needle is fixed with the index finger and the piston with the little finger.
- Having placed four fingers of the syringe-free hand under the patient’s hand, the vein is fixed with the thumb with a light pull on the skin.
- The skin is pierced, and the needle is inserted directly into the vein.
- With your free hand you need to pull the piston. The presence of blood in the syringe indicates that the needle is in the vein.
- The tourniquet is removed and the patient can open his fist.
- To make sure that the needle does not come out of the vein, you need to pull the piston again.
- A drug is slowly injected from a syringe into a vein.
- The needle is removed from the vein, and a previously prepared cotton ball is pressed to the puncture site. Let the patient, bending his arm at the elbow, hold until the bleeding stops completely.
That's the whole technique. I wish you to always come across excellent specialists and good health to you!
