Some people even have visited doctors for a couple of times in their lives. Of course, the less you face the need for attention from doctors, the better – it means that health is in order. However, some idea of the most common procedures is still worth it: who knows at what point they can come in handy.
Ordinary people use simpler terms than “infusion” and “injection”. Instead of the last word in everyday life appears more familiar injection. Probably, everyone faced such a procedure – at least once in their life, at least at a dentist. Its meaning: the rapid introduction into the body of a drug in a strictly defined quantity. Injections are equally important when a person cannot take the medicine himself – either as a result of fainting, or as a result of vomiting, or as a result of the fact that the drug cannot be taken by swallowing (for example, it is destroyed by the aggressive environment of the stomach). There are several types of injections. Such as subcutaneous and intramuscular, can make even a person without special education. Some (in particular, diabetics) even prick themselves the medicine themselves. The main thing is that the skin is disinfected, and the syringe is sterile. Naturally, intra-articular, intravenous and intraosseous injections can only be “delivered” by a health worker.
More complicated procedure
We will understand now with the concept of infusion. That this word is synonymous with the familiar term “dropper”, fewer people already know. The meaning of the procedure in the slow but continuous flow of the prescribed drug in the patient’s blood. The needle (catheter) is inserted either into the vein or into the artery. Other way can not be carried out infusion. It is clear to everyone that this is a complex process that requires proven skills and is fraught with deadly consequences in case of an error. So at home, “on the knee”, you can’t put a dropper, you must have medical supervision.
What goals do doctors pursue when prescribing an infusion?
With a fairly extensive list of diseases, the patient needs just an infusion. What are these cases? First of all, a large blood loss. You cannot restore it without a dropper. The next option is nutrition of the body, which itself cannot temporarily take in food (for example, after operations on the intestine and stomach; with a long lack of nutrition, when the gastrointestinal tract has “forgotten how to work”; with a general weakness of the body). Intravenous infusion is extremely necessary in the treatment of cancer: drugs for some time should be in a given concentration in the blood. Single injections here is not enough. In the same way, the missing blood components (red blood cells and platelets) are delivered.
Varieties of procedure
In principle, they are two, if you focus on how to infusion. What kind of species are these? Inkjet and drip. Jet infusion is done when the desired medicine is in a small volume, or it needs to be injected into the body very quickly. Drip, on the contrary, suggests a low, but constant speed and a large amount of the drug (or blood, or plasma). Its distinctive advantage is that the internal pressure on the walls of the veins and arteries practically does not change, that is, the infusion is done in a softer, sparing mode. The disadvantage here can be considered a very long time, which will have to spend under a drip.
Modern devices, through which intravenous infusion is carried out, are equipped with a special safety valve, which closes the IV when the solution ends. However, some hospitals still use old systems where there is no such valve. In this case, the medical staff or relatives of the patient have to monitor the level of the solution so that no air bubble gets into the vein.
