Intravenous injection - Prick in the vein

I will tell you about the injections, better known to an ordinary person, as a "prick in a vein." Intravenous injection is the administration of the drug directly into the blood (bloodstream). I myself did it perfectly at the time, when I was practicing from a medical school in an emergency hospital. I can do it today and believe that any health worker should not only know how to make intravenous injections, but also technically and competently perform them.

Recently heard, how the woman told, that physicians do not get into her veins from the first time. She also casts doubt on the qualifications of nurses. The fact is that such a phenomenon actually takes place.

Case in the manipulation room

The case was in one regional polyclinic. The name of the settlement does not matter, as it could happen anywhere. Unfortunately, personally I repeatedly had to deal with such cases, when intravenous injections were made, the technique of performance of which left much to be desired.

So, in the district clinic, the patient was given an intravenous injection of glucose. Omitting the details, it is worth noting only the fact that the man was stripped of all the forearm, and then the hands. The injection in the vein was never carried out until the specialists from the intensive care unit came. So it should not be, of course. Imagine that once in a similar situation I injected myself into manipulation. It was necessary, however, to show the 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, a pry into the vein tried to perform the intern. I remember how the students of the medical school were not admitted to the patients until we had sufficiently practiced each other. Perhaps because we were trained as military paramedics for the army, any student of our group could do any injection almost with his eyes closed.

Types of injections

• Intramuscular. This, perhaps, is the most common and simple.
• Intradermal. For the purpose of diagnosis (allergic tests), prevention (vaccination).
• Subcutaneous.
• Intravenous injection. The technique of implementation will be described below.
• Intraarterial.
• Intraosseous.

The technique of performing intravenous injection

• First you need to sit or lay the patient. If necessary, a person should be reassured.
• It is necessary to lay a special roller under its elbow fold.
• The application of a venous tourniquet is made from the bottom upwards above the fold. Apply should not be on the naked body and tighten the tourniquet unnecessarily.
• Let the patient "work the fist" (several times squeeze and unclench the fist), and then compress it and do not unclamp until the end of the procedure.
• The place in which the intravenous injection will be performed must be treated with alcohol with a cotton ball soaked in it. In this case, the first cotton ball should be treated with a larger area around the intended injection site. The second ball must be processed directly by the injection site itself into the vein (puncture). Movement is performed from the bottom up, as a result, the vein becomes more accessible due to the influx of blood. Another alcohol-soaked ball is taken under the little finger of the syringe-free hand.
• The syringe is taken into the hand, the cap is removed from the needle. It is necessary to squeeze the air from the syringe with a slight pressure on the piston. Keep it up by pointing the needle upwards. The cannula is fixed with the index finger and the piston with the little finger.
• Having brought four fingers free from the syringe hand under the patient's arm, the vein is fixed by the thumb with the help of a slight pull on the skin.
• The skin is pierced and the needle is inserted directly into the vein.
• You need to pull the piston with your free hand. The presence of blood in the syringe indicates that the needle is in the vein.
• The tourniquet is removed and the patient can unclench the fist.
• To make sure that the needle does not come out of the vein, you need to pull the plunger again.
• Slowly injected from the syringe into the vein drug.
• The needle is removed from the vein, and the cotton ball prepared earlier is pressed against the puncture site. Let the patient, bending his arm at the elbow, hold him to a complete stop of the bleeding.

That's all the equipment. I wish that you always come across excellent specialists and good health to you!
