The fact is proved that the body of any person, regardless of his age, is 75-80% water. In this environment, metabolic processes occur, transportation of various substances and dissolved gases, so the ability to influence the functions of various organs and systems of the body (infusion therapy) in modern medicine is becoming an increasingly popular treatment method. When injecting into the vascular bed solutions of various compositions, with different physicochemical characteristics, the doctor is able to quickly respond to the symptoms of pathological conditions and restore the constancy of the internal environment of the body.
Infusion therapy - what is it
Each doctor will say that infusion therapy is the introduction into the body of solutions of various compositions. In some cases, an additional amount of electrolytes is introduced during infusion, which helps to control the acid-base state of the blood, in others - colloidal solutions, regulating the amount of fluid in the body, and in the third, blood components and blood substitutes can enter the vascular bed. In each case, the doctor (or a panel of specialists) decides which drug is indicated to the patient, and selects the desired volume of solution for infusion or the concentration of the desired drug.
What is infusion therapy for?
Most often, infusion therapy is necessary to correct the volume of fluid that circulates in the vascular and extravascular beds, or to maintain the constancy of the salt composition of the body (ion balance). In many respects, the ability of the body to regulate the acid-base state and remove toxic substances depends on these factors. Without removing toxic products from the body, it is impossible to imagine the patient recovering from a large number of infectious diseases and inflammatory processes, recovering from the postoperative period and after poisoning.
Much less often, infusion-transfusion therapy is used for passive immunization of the patient's body in the prevention and treatment of certain infectious diseases or for feeding seriously ill patients with the inability to receive food through the gastrointestinal tract. In addition, this treatment method is used for parenteral administration of various drugs - the use of this treatment method allows you to quickly achieve the desired result (stabilization of the patient's condition), which is in demand in the intensive care unit and intensive care.
How is infusion therapy carried out?
Only a doctor can decide whether or not infusion therapy is indicated for a particular patient, which solutions or drugs should be used to administer it and prescribe a dosage. Regardless of the patient’s age, treatment should be carried out not only under constant medical supervision, but also under constant instrumental and laboratory monitoring of the main vital signs of the body. Infusion therapy in children deserves special attention, because this treatment method allows you to quickly make up for the loss of fluids and salts, to which the body of a small patient is very sensitive.
In the vast majority of cases, transfusion therapy requires reliable venous access through which all prescribed drugs will be administered. Depending on the patient’s condition, even before the start of infusion therapy, a permanent catheter is inserted into a large peripheral or one of the central veins, the use of which allows for long-term (regular) infusions with minimal discomfort.
