Catheter Colonization
With aseptic technique, the central venous catheter will be withdrawn and a 5 centimeters distal portion of the catheter will be cut and conditioned in sterile test tube and sent to the microbiology laboratory. It will be considered a Catheter Colonization a significant growth of one or more microorganism in a semiquantitative culture of the catheter tip. It is according to the Clinical Practice Guidelines for the Diagnosis and management of Intravascular Catheter- Related Infection: 2009 Update by the Infectious Diseases Society of America
Time frame: Participants will be followed from placement until the withdraw of the central venous catheter, an expected average of 3 weeks.
Microbiological Exit site Infection
With aseptic technique, a swab will be collected before removal of central venous catheter, the swab will be moistened with sterile saline and rolled for about 2 cm around the exit site. The material will be conditioned in sterile test tube and sent to the microbiology laboratory. It will be considered a Microbiological Exit Site Infection the exudate at catheter exit site yields a microorganism. According to Clinical Practice Guideline for Diagnosis and Management of intravascular Catheter-Related Infection: 2009 Update by the Infectious Diseases Society of America
Time frame: Participants will be followed from placement until the withdraw of central venous catheter, an expected average of 3 weeks
Clinical Exit Site Infection
Erythema, induration, and/or tenderness within 2 cm of the catheter exit site, according to Clinical Practice Guidelines for the diagnosis and management of intravascular Catheter-Related Infection: 2009 Update by the infectious diseases Society of America.
Time frame: Participants will be followed from placement until the withdraw of central venous catheter, an expected average of 3 weeks
