Süstelvedelikud

Süstelvedelikud, also known as parenteral fluids, are sterile solutions administered to the body via injection or infusion, bypassing the digestive system. They are primarily used to restore fluid and electrolyte balance, administer medications, provide nutrition, and facilitate blood transfusions.

The composition of süstelvedelikud varies widely depending on their intended purpose. Common types include isotonic solutions like normal saline (0.9% sodium chloride) and Lactated Ringer's solution, which have similar osmotic pressure to body fluids and are used for hydration and electrolyte replacement. Hypertonic solutions, such as 5% dextrose in normal saline, have a higher concentration of solutes and are used to treat hyponatremia or to provide calories. Hypotonic solutions, like 0.45% sodium chloride, have a lower solute concentration and are used to treat cellular dehydration.

Specific süstelvedelikud formulations also exist for nutritional support, containing carbohydrates, amino acids, lipids, vitamins, and minerals. These are crucial for patients who cannot obtain adequate nutrition orally or enterally. Blood products, such as packed red blood cells, plasma, and platelets, are also administered parenterally for conditions like anemia, clotting disorders, and severe blood loss.

The administration of süstelvedelikud is a critical medical procedure requiring sterile technique to prevent infection. Common routes of administration include intravenous (IV), intramuscular (IM), and subcutaneous (SC) injections, with IV being the most common for rapid systemic delivery. Careful monitoring of fluid balance, electrolyte levels, and potential adverse reactions is essential during and after administration.
