What is a potential complication of administering normal saline too quickly?

Administering normal saline too quickly can lead to fluid overload, a significant complication that occurs when the body cannot handle the excess fluid being introduced into the bloodstream. This can result in various symptoms and medical issues, including elevated blood pressure, swelling in the extremities, and pulmonary edema, where fluid accumulates in the lungs. Fluid overload can place additional strain on the heart and lead to serious complications, particularly in patients with pre-existing conditions such as heart failure or renal impairment.

Understanding the risks associated with the rapid administration of intravenous fluids is essential for patient safety and effective treatment. It stresses the importance of monitoring the patient's response to the infusion and adjusting the rate as necessary to prevent complications linked to fluid volume excess.
