Infusion therapy is a method of providing the body with water, drugs, nutrients and electrolytes parenterally. These substances are introduced into the body intravenously, intraosseously, intraarterially.

Instructions

Step 1

The purpose of infusion therapy is to maintain body functions. Its tasks are: provision of a normal volume of water, blood plasma, restoration of blood properties, detoxification, uniform and long-term administration of drugs, provision of parenteral nutrition, normalization of immunity.

Step 2

The most commonly used is venous access. It is provided with the help of a vein puncture (for short droppers), venesection (if necessary, continuous administration of drugs for several days), catheterization of large veins (for infusion therapy lasting up to several months). Infusion therapy methods: continuous (drip) and intermittent (jet) administration of solutions. For the injection of drugs, syringes are used, for continuous administration, drip infusion therapy systems are used.

Step 3

The rate of introduction of solutions is measured in the number of drops per minute. The number of drops in 1 ml of solution will depend on the surface tension created by the solution and on the size of the dropper. Solutions for infusion therapy are divided into several groups: basic, volume-replacing, corrective and parenteral nutritional preparations.

Step 4

Volume-replacing drugs are divided into: artificial plasma substitutes, natural (autogenous) plasma substitutes, blood, erythrocyte mass. They are used to replace the volume of plasma, with a deficiency of erythrocytes or other plasma components, to restore blood functions. With the help of basic solutions, drugs and nutrients are introduced into the body. Corrective solutions are used for hypovolemic shock, ion imbalance.

Step 5

In the course of infusion therapy, its effectiveness is continuously assessed by changing the state of the pulse and the color of the skin, lips, nails, kidney function, respiratory system and central nervous system. Before the start of therapy, after its initial stage and daily, the indices of the content of total protein, calcium, urea, glucose, NaCl, blood coagulation time, prothrombin level, and the relative density of urine are determined.

Step 6

Complications of infusion therapy are: hematomas, tissue necrosis, damage to adjacent tissues and organs, thrombosis and phlebitis, embolism. Possible development of water intoxication, edema, acidosis, hyperthermia, anaphylactic shock, chills, circulatory disorders, drug overdose. There are complications associated with blood transfusion, overload of the circulatory system due to an excess of injected solutions, pulmonary edema.
