Compact Closed System Versus Mounted Open System (COSMOS)

The purpose of this study is to investigate, in a prospective and randomized fashion, the clinical performance of a closed intravenous system versus an open conventional one, with respect to ease of handling and effectiveness (as defined by time of survival without complications), security provided to professionals and patients against accidental blood exposure or needlestick injury, catheter-related complications such as phlebitis, pain and blockage and overall costs of the two systems.
