Clinical review: Vascular access for fluid infusion in children

The current literature on venous access in infants and children for acute intravascular access in the routine situation and in emergency or intensive care settings is reviewed. The various techniques for facilitating venous cannulation, such as application of local warmth, transillumination techniques and epidermal nitroglycerine, are described. Preferred sites for central venous access in infants and children are the external and internal jugular veins, the subclavian and axillary veins, and the femoral vein. Femoral venous cannulation appears to be the most safe and reliable technique in children of all ages, with high success and low complication rates. Evidence from the reviewed literature strongly supports the use of real-time ultrasound techniques for venous cannulation in infants and children. Additionally, in emergency situations intraosseous access has almost completely replaced saphenous cutdown procedures in children and has decreased the need for immediate central venous access.
