Analysis Of Risk Factors Of Hemodialysis Semi - Permanent Dialysis Catheter Associated Infection

Background : Analysis of semi-permanent dialysis hemodialysis catheter-related risk factors for infectionMethods: Select 2011.12-2014.12 404 Weihai Hospital Nephrology semi-permanent treatment of dialysis patients with indwelling catheters in 29 cases. 28 cases of the use of the right internal jugular vein catheterization, one case in the left jugular vein catheterization using(the right internal jugular vein malformation, stenosis).Seldinger technology than patients with avulsion sheath puncture and catheter method.The catheter-related infections diagnostic criteria: â‘  exports infections: skin within2 cm at the outlet conduit within the scope of redness, swelling, pain, purulent secretions or culture positive, with or without bloodstream infection. â‘¡ tunnel infection: infection along the direction of the catheter port and catheter infections continue over 2cm. Parts of the tunnel may have local pain, swelling, fever, along conduit opening after extrusion may have purulent discharge outflow, with or without associated bloodstream infections,secretions culture positive. â‘¢ catheter-related bacteremia(CRB) performance: the emergence of the dialysis process chills, fever, and some immunocompromised patients,showed only fever, low blood pressure, low blood sugar. Diagnostic criteria: positive blood culture within the conduit, the inner conduit blood culture the number of colonies greater than 100 cfu / ml, within the catheter and peripheral blood cultures of the same bacteria, catheter blood culture bacteria to the number of bacteria in peripheral blood of 5times. More than 29 people will be divided into groups of catheter-related infections(infected group) and no catheter-related infection(non-infected group).Analysis of age,gender, living environment, hemoglobin, serum albumin, serum creatinine, primary disease, catheter time and catheter-related infections correlation. Statistical analysis:catheter-related infections incidence of cases of infection with a catheter and catheter days than to indicate that the cases / 1000 catheter-days. Statistical analysis was performed using SPSS11.0 software. Count data using chi-square test, P <0.05 wasconsidered statistically significantResults:1. The living conditions of poor sanitation, hemoglobin <90g / L, is a semi-permanent dialysis catheter-related risk factors for infection, P <0.05.2. Gender, age, serum albumin, serum creatinine, primary disease, catheter time and other single factor and semi-permanent dialysis catheter-related infection rate was no significant correlation, P> 0.05.Conclusions:Living conditions of poor sanitation, hemoglobin <90g / L, may be risk factors of catheter-related infections.
