Which symptom might indicate a complication during IV therapy?

Redness or swelling at the insertion site is a significant symptom that may indicate a complication during IV therapy. Such symptoms can suggest that an infusion is not proceeding as intended, possibly pointing to phlebitis, infiltration, or even an infection at the site.

Phlebitis is an inflammation of the vein that can result from irritation due to the catheter or the fluids being infused. Infiltration occurs when IV fluids leak into the surrounding tissue instead of being delivered into the vein, leading to swelling and potential tissue damage. Recognizing these symptoms early is crucial for preventing more severe complications, such as abscess formation or systemic infection.

In contrast, increased urine output, improved oxygen saturation, and stable blood pressure typically indicate that the body is responding well to treatment. These should not be construed as complications during IV therapy but rather as positive signs indicating that the therapy is effective and that the patient is likely maintaining stable homeostasis.
