Peripheral IV lines are essential in pediatric care for several reasons: - Hydration: Children who are dehydrated due to illness or surgery can receive fluids intravenously. - Medication Administration: Some medications need to be administered directly into the bloodstream for rapid effect. - Nutritional Support: In cases where children cannot eat, nutrition can be provided intravenously. - Blood Sampling: Frequent blood tests can be performed without repeated needle sticks.
