Vascular access refers to the methods and techniques used to access the bloodstream for medical treatment, such as medication administration, fluid resuscitation, or blood sampling. In clinical practice, vascular access is essential for patients who require frequent or prolonged intravenous therapies. Common methods of vascular access include peripheral IV lines, central venous catheters, and arteriovenous fistulas. Research in this area focuses on improving the safety, effectiveness, and efficiency of vascular access procedures, as well as reducing complications and infections associated with these interventions. This research also explores innovative technologies and interventions to optimize vascular access for patients in various clinical settings.
