Abstract:
OBJECTIVE To investigate the patterns of catheter related infection in critically ill patients after cardiac surgery with prolonged central venous catheters. METHODS The materials of culture of catheter tip and subcutaneous segments in 166 critically ill patients after cardiac surgery with prolonged central venous catheters were reviewed. RESULTS The positive pathogenic bacteria ratio of catheter tip segments was 41.0% and the positive ratio of catheter subcutaneous segments was 47.0%.Catheterization longer than 18 days,body temperature higher than 38.5 ℃ and insertion sites of femoral veins were the variables associated with significantly increased risk of catheter related infection. CONCLUSIONS The positive pathogenic bacteria ratio of central venous catheters in critically ill patients after cardiac surgery with prolonged central venous catheters is high,more attention must be paid to catheter related infection,and efficacious interventions must be laid down.
