Abstract :

Background :The present study entitled “ central venous catherter related blood stream infection intensive care unit” was undertaken to find out the microbiological profile and antibiotic sensitivity pattern of infections of temporary non–tunneled double lumen central venous catheters in ICU.

Methodology :It is a prospective study including 111 patients, was allocated randomly. Out of 111 catheterizations, 51 were inserted in femoral, 40 were inserted in IJV  and 20 were inserted in subclavian vein.

            Patients between of age group 18 to 75 years were included.  our study observed the incidence of infections, various factors influencing the infections, differentiation between contaminations and CRBSIs, identify the organisms involved in causation of CRBSIs, antibiotic sensitivity patterns of isolated organisms.

Results :  In our study with IJV catheters, 6.3% of infections happened in 8–15 days of catheterization but 93.8% of infections happened in 16–21 days of catheterization. P value is less than 0.05 which is statistically significant. But with femoral catheters 3.6 % of infections happened in 1–3 days of catheterization, 7.1% of infections happened in 4–5 days of catheterization but 89.3% infections happened in 6–7 days of catheterization. But these values were not statistically significant (p=0.76).

 In our study Out of total 28 femoral catheters, 4 catheters (14.28%) showed CRBSI, out of 16 IJV catheters, 4 (25%) showed CRBSI and out of 8 SCV catheters, 1 (12.5%) showed CRBSI. We found IJV catheters were associated with increased risk of infection compared to femoral and SCN but the p value is statistically not significant (p=0.62).

Conclusion :IJV and Femoral site catheterizations are associated with more infections compared to subclavian site.Patients who require CVC more than a week, femoral catheterization is discouraged expect in emergency situations.Vancomycin is the empirical drug of choice for gram positive organisms and Imipenam/Meropenam is the drug of choice for s gram negative organism. Femoral catheters should be removed by 7 days and IJV and SCV by 21 days. Catheter site should be checked regularly and proper dressing should be done.
