Infection Rate of Different Approach for Central Venous Catheter Placement after Cardiac Surgery

Objective To observe the infection rate of different approach for central venous catheter placement after cardiac surgery and explore the related risk factors,prevention and control measures,so as to provide references for the clinical preventive practices and reducing CVC-correlated infections.Methods The 198 cases of open heart surgery from 2009 to 2010 were enrolled in this study.They underwent the central venous catheter placement by approaches of femoral vein,subclavian vein or peripheral venous.The clinical materials of patients with a positive result of bacterial culture of the catheter tips were collected and analyzed with statistical techniques.Results The infection rates of subclavian vein,femoral vein,peripheral venous catheter-related were 7.84%,23.6% and 6.89%,respectively.Among the infectious pathogenic bacteria in central venous pipeline,there were 12 cases of gram-positive bacterium which account for 57.1%,8 cases of Gram-negative bacterium for 38.1% and 1 case of fungus for 4.8%.Conclusion The different degrees difference in the infection rates was founded among different approaches which the central venous catheter was placed.The differences between the puncture of femoral vein and subclavian vein or the peripheral vein are statistical significant(P0.05).The gram-positive bacteria play a key role in the catheter-related infections.
