Not Applicable

• Conditions: Catheter-related Bloodstream Infection; Complication of Catheter

• Registration Number: NCT01603914

Brief Summary

The aim of this project is to answer the following questions:

To determine the incidence of catheter related bacteremia (CRB) with three strategies of central venous catheter exchange in critically ill adult patients with major burn and to determine the regimen that will minimize the risk of bacteremia.

To determine the incidence rate of catheter colonization in adult patients with major burns.

The scientific knowledge to be acquired through this project is of likely benefit to the care of critically ill patients with burns injury as follows:

The intention is to improve the outcomes in critically ill patients by minimizing one of the most frequent causes of infection in the Burn Intensive Care Unit, those from central venous catheters. Decreasing infections will decrease morbidity, decrease length of stay, decrease costs, and decrease mortality.

Detailed Description

Aim: To determine the incidence of catheter-related bacteremia (CRB) with three primary schedules of central venous catheter exchange in adult critically ill patients with major burn injury.

Hypothesis: A strategy of catheter exchange according with clinical criteria will result in no more CRB compared with a routine catheter changes without guidewire exchange strategy or frequent guidewire exchange or frequent new-site replacement.

Background: The intravenous catheter-related bacteremia (ICRB) is a nosocomial infection affecting patients admitted to intensive care and that leads to increased morbidity. Accumulative incidence rates of ICRB are 5.5 infections per 1000 catheters-day. Several strategies have been proposed to decrease of the rate of ICRB in critically ill patients. However, there is not agreement to recommend a replacement pattern of central venous catheters in adult critically ill patients with major burns as a strategy for the reduction in intravenous catheter-associated bacteremia.

Objectives. To compare three strategies of replacement from central venous catheters for the prevention of ICRB. Find out the risk of mechanical complications associated with each strategy of central venous catheter replacement.

Method. Randomized, multicenter clinical trial, single blind to compare three strategies for intravenous catheter replacement in patients with major burns: a scheduled wire-guided strategy every six days: second, a scheduled strategy of replacement every six days in a different punction and third, a re-change strategy guided by clinical criteria for suspicion of catheter-associated infection. Primary outcome: catheter colonization rate and rate of intravenous catheter-associated bacteremia. Secondarily, we calculate the incidence rate of colonization of central venous catheter and finally we will analyze the associated complications.

This project requires enough patients to show a difference between three intervention groups. A significant decrease in infection rate would be from the current 20 infections per 1000 catheter days to approximately 15 per 1000 catheter days. This would require a minimum of 1000 catheter days per group.
