What is an intravenous injection?
Intravenous means “within a vein.” Generally, it refers to giving medicines or fluids through a needle or tube inserted into a vein. This method allows the medicine or fluid to enter the bloodstream right away.
Also, some of the drugs for treatment that need to be administered intravenously are often given by intravenous injection. In IV (intravenous) applications, the duration of the treatment and the patient’s vascular status should be taken into account when selecting the proper vein. More than 80% of hospitalized patients receive intravenous therapy. It is preferred for the inconvenient drugs to be administered quickly and when more than one drug needs to be administered, mixed into the serum and administered slowly.
Why use intravenous injection?
Intravenous administration of drugs provides a faster onset of action than other methods. Some drugs can only be given intravenously. It is also possible for many drugs to be taken orally or by intramuscular injection instead of intravenous injection. The most commonly used veins for intravenous access are the antecubital (front of the elbow) veins located in the elbows in the arms.
A rubber cuff is bound to the arm. In this way, it becomes visible and palpable under the skin by filling the vein with blood. The entry point is determined by visualizing the vein or sometimes by feeling it with the fingers. This point and the determined area around it are sterilized, and the vein is entered with the appropriate needle. Sometimes, the veins in front of the elbow cannot be found if they are very thin. In these cases, other veins are searched.
