The concept of inotropic does not appear in the dictionary of the Royal Spanish Academy (RAE ). However, it is a term often used in the field of medicine .
An inotropic is a substance that causes effects on the muscle contractility . The inotropic effect can be negative (if the constriction decreases) or positive (if increased).
The quality that alters the contractility of the muscle is called inotropism . It is common for the idea of inotropism to be used with respect to the heart: in cardiology Inotropic medications are common.
When a person you suffer from heart failure, for example, you may receive an inotropic treatment. Inotropic drugs are also prescribed after cardiovascular surgery.
Inotropics are also used in situations of emergency : A patient with a hypotension (drop in blood pressure) or with a circulatory collapse may need these drugs.
Inotropic medications are given venously and act on the heart cells and the walls of the arteries . Among the most used inotropics are dopamine, norepinephrine, dobutamine and levosimendan.
It is important to mention that, beyond their medicinal utility, inotropics can cause certain adverse effects. Vomiting, nausea, arrhythmias and increased blood pressure are some of these unwanted consequences.
It should be noted that doctors They are the professionals indicated to advise on inotropics, explain their operation and prescribe their supply. These specialists have the necessary knowledge for the correct treatment of their patients .
Simply put, the effect that inotropic drugs produce in cardiac contractility and peripheral blood vessels is immediate and for this reason they are framed in the group of vasoactive drugs . Among the various products of this family we find the vasodilators , the vasoconstrictors and a third group that has different effects depending on the dose applied to the patient; Dobutamine, norepinephrine and dopamine are three respective examples of such types of inotropics.
In the unity intensive care (abbreviated ICU) In almost all hospitals we find inotropic drugs, since they are necessary substances in extreme cases, in which the patient's life is at stake (some common examples are pulmonary embolism, septic shock and cardiogenic shock).
As in almost any emergency situation of an intensive care unit, the reaction of the professionals of the Health It must be very fast for the assistance procedures to be successful. Many times the decisions are appropriate but fail because they are not implemented immediately.
To carry out the administration of an inotropic drug, an infusion pump is used that allows it to be deposited directly into a vein. It is important to note that most of these patients receive more than one medicine at the same time, which is why they must be connected to several pumps simultaneously.
The most common type of infusion pump in these cases is the syringe, because it gives very precise results in contrast to the volumetric, which is more frequent in the infusion of fluids. The infusion process cannot be interrupted to replace a syringe , not even for a few seconds. For this there are double pumps, which are activated alternately manually: just at the moment when the first one is emptied, the operator must start using the second one.
Currently there are bombs Infusion of inotropic drugs that have technologies such as infrared ports for wireless transmission of different data that facilitate the operation and offer a greater degree of accuracy than the old ones.
