What is intravenous infusion therapy?

Intravenous infusion therapy involves directly administering medications, nutritional fluids, and other substances into the body through veins. This method enables rapid therapeutic effects and precise drug delivery, making it suitable for treating and supporting a variety of medical conditions. If discomfort such as dizziness, palpitations, or skin itching occurs during infusion, prompt medical attention is recommended.

This treatment involves inserting an infusion needle into a vein under sterile conditions, allowing medications to enter the bloodstream directly and reach the target site or circulate throughout the body. By bypassing gastrointestinal absorption, it avoids associated losses and can achieve effective blood drug concentrations quickly, making it especially suitable for critically ill patients who cannot take oral medications.

Common indications include rapid anti-infective treatment for severe infections, fluid and electrolyte replacement in dehydrated patients, provision of parenteral nutrition for those with inadequate nutrient intake, and administration of certain chemotherapy and emergency drugs. This therapy must be strictly used according to medical instructions.

During infusion, keep the puncture site clean and dry, avoid strenuous activities to prevent dislodging the needle, maintain a steady drip rate without adjusting it manually, and follow a light diet avoiding spicy or irritating foods to ensure safe and effective treatment.
