Intravenous Administration

Intravenous administration is the delivery of substances directly into the bloodstream via a vein, allowing for rapid onset of action and precise control over drug dosage. This method is crucial in clinical practice for administering medications, fluids, and nutrients, particularly in emergency situations or when patients cannot take oral medications. A key complication associated with this technique is phlebitis, which is inflammation of the vein, potentially leading to discomfort or infection.
