title: Vascular access.
abstract: Vascular access is the cornerstone of medical therapy in the pediatric population and presents unique challenges. The vessels are small, often exceedingly so, and gaining access may require considerable patience and skill. Peripheral IVs are difficult to place in children, both because of lack of patient cooperation and because of the very small size of many veins. In addition, repeated venipuncture has been identified as one of the greatest stresses in hospitalized children. In the recent past, all forms of central venous access were the preserve of surgeons and were placed in the operating room under general anesthesia. In recent years, pediatric interventional radiologists have described placing peripherally inserted central catheters (PICCs), subcutaneous venous access ports, hemodialysis catheters, and a variety of temporary and permanent central lines even in the smallest children. This has been achieved safely, reliably, and, by dispensing with general anesthesia and operating room time in most cases, at considerable cost savings to the entire health care system. In addition, new forms of reliable, stable access such as the PICC line have made possible outpatient treatment of a wide variety of conditions, particularly infectious, which previously necessitated hospital admission. This has resulted not only in considerable cost saving for the health care system but also improved quality of life for the patient and their family. In this section, I review the current state of pediatric vascular access with emphasis on those areas where pediatric differs from adult practice.
