The multi-lumen intravenous extension system and method for independently conveying medicinal fluids include an extension including an elongate cylindrical body having a main lumen extending axially therein and at least one satellite lumen extending parallel with the main lumen in the extension, a coupling/connector at a proximal end of the extension, a liquid supply system connected to the proximal end connector for delivering liquid to the main lumen, at least one syringe coupled to the proximal connector for supplying a drug medication, pharmaceutical agent, or other liquid to the satellite or secondary lumen, and a connector forming a mixing chamber coupled to a distal end of the extension. The connector is adapted for connection to an intravenous or intra-vascular catheter or needle leading to an intra-vascular access site. The fluidic connection between the mixing connector and the multi-lumens of the extension substantially prevents over-pressurization of the vascular access device.
