In order not to lie in the hospital, many patients are ready for any sacrifices, even independent injections at home. Here begins the main problems that are associated with the search for medical staff who will perform the procedures at home. If it is not possible to find a specialist, the majority of patients begin to make injections on their own, which may be associated with some problems.
What happens if air is injected intravenously?
Air trapped in a vein is one of the most beloved scripts of literary detectives. Evidence of the murder is hard to find, as a rule, the pathologist does not see on the body of the injection trail and the most interesting begins ... So, is it really possible to die if you violate the safety of the injections? Or if the air gets into the vein?
In fact, not so simple. From the ingress of air into the vein does not have to wait for anything good, but death is unlikely. When air enters the vein during injections, a so-called air embolism develops, which, of course, can be fatal, but it all depends on the volume of injected gas. Since, for lethal outcome, the air must get into the artery, and in the large. Yes, and the amount of volume must be large in order to completely block its flow.
The term embolism refers to the presence of any major moving obstacles in the bloodstream. In an air embolus, an air bubble will be an obstacle. By the way, it is in this scenario that decompression sickness develops. Symptoms of an air embolism are dizziness, tingling, or numbness in the area where the air bubble is moving; in very severe cases, when the gas bubble is large, paralysis can form.
Airborne embolism, in most cases is not fatal, but unpleasant. For these reasons, in order to avoid such consequences, all medical personnel strictly monitor that there is no air left in the syringe / system. Moreover, modern devices for intravenous infusions are equipped with security systems.
And if the air gets intramuscularly?
As a rule, this is the most typical mistake of all newbies. The ingress of air by intramuscular injection does not pose a threat to the health, and even more so the life of the patient.
Scenario 2 scenario development - air will get into the muscle or into the vessel. If gas enters the muscle, the body will cope with the problem on its own, and the patients themselves simply do not notice it. But do not abuse the reserve and recovery forces for the body.
If an air bubble enters the vessel and is large enough, it can be blocked. But it will not bring any harm to the body, except for blocking the capillary and forming a bump, bruise.
How to make an injection: a description
Ideally, you should entrust this procedure to professionals who have taken special courses. If there is no such possibility, but it’s necessary to do it, then you need to follow the following rules.
- Any injection begins with preliminary preparation, namely washing hands and preparing tools. After washing your hands under running water, you can proceed to the preparation of injection solution. It is necessary to begin with the preparation of ampoules, which must first be treated with an alcohol solution.
- Only then can you open the vial and packing with a syringe. When collecting the syringe, it is necessary to hold the needle by the cannula and put it on it, only after that remove the protective cap.
- Having collected the solution in the syringe, it is necessary to get rid of all the air bubbles and release a couple of drops of the solution - thereby getting rid of the oxygen in the needle.
- Having prepared the solution, you can proceed directly to intramuscular injection. The selected buttock for injection must be visually divided into 4 quadrants, and vcol in the upper right corner, after having previously treated the place of vcol with alcohol wipes.
- It is necessary to inject on ¾, the introduction of a full needle is undesirable, since there is a high risk that it will break off.
- To enter the solution, it is necessary slowly. After insertion, hold the place of vcol with an alcohol wipe and pull out the needle at a right angle. The procedure is complete.
- Preparation for the procedure is similar to preparation for intramuscular injections, with the only difference being that the system can be used instead of a syringe. There should also be no air in the system.
- After it is necessary to choose the right vein, namely contoured - easily visible, which stands above the skin and has the greatest thickness. The patient's arm should be in a straight position, and the patient should be comfortably arranged.
- Next, you need to put a tourniquet above the elbow on the full palm, fixing the tourniquet, the patient must make several movements on the compression and release of the fist. Thus, the veins "swell" and easier to view.
- Having chosen the place of injection, it is necessary to treat the area with an alcohol solution. In one hand a syringe, the other hand should fix the skin in the area of the elbow bend. The hand in which the syringe is located must be at an acute angle to the vein, after which the needle is injected and the needle is inserted into the vein 1/3 the length. In this case, the patient clenches his fist.
- When you inject felt the needles fall through. In order to make sure that the needle is in the vein, it is necessary to slightly pull the plunger of the syringe toward you, blood will be drawn into the solution. Only in this case, you can continue.
- While the needle is in a vein, it is necessary to remove the tourniquet, and the patient opens his fist, a slow injection of the solution begins. Different solutions have some restrictions on the introduction - jet, drip, respectively, it is necessary to introduce the drug in accordance with these characteristics.
- As soon as the solution was injected, it is necessary to press the needle with a cotton swab, gently pull it out. The patient should bend the arm in the elbow, hold it in this position for several minutes. Thus, a blood clot will form and bleeding will stop.
When performing injections, it is worth remembering about the safety technique, because there is work with blood, no one is immune from the transmission of certain diseases or the addition of infection. After the injection, it is necessary to dispose of the tools according to the rules. Needles from syringes should be tightly closed with a cap.
