010, 0.013, and 0.053). The mean EHRI value was higher in patients with AMC than in patients without AMC (p = 0.043). The patients were divided into tertiles BIBW2992 according to their EHRI values. Six (21.4%) patients in T1 group, 12

(42.9%) patients in T2 group, and 17 (60.7%) patients in T3 group showed arterial micro-calcification, respectively (p = 0.012). In the multivariate logistic regression analysis, diabetes and ESA hypo-responsiveness showed a significant association with arterial micro-calcification. Conclusion: ESA hypo-responsiveness as well as diabetes may be clinically relevant parameters related to AMC in HD patients.

Our study aims to determine the rate and time to development of CRBSI using 70% ethanol lock in comparison with heparin lock 20 min prior to initiation

of hemodialysis. Methods: Double lumen polyurethane hemodialysis catheter was used. 70 patients were randomized to one of two solutions: Heparin (1000 U/ml) or Ethanol (100% absolute ethanol diluted to 70%), prior to hemodialysis, both the catheter lumens were filled with respective solution and 20 min of dwell time was given. The solution was then withdrawn, flushed with normal saline and hemodialysis started. All the catheter lumens irrespective of randomization were locked during the interdialytic period with heparin. Fever was evaluated with blood cultures and antibiotics given. Results: CRBSI occurred

in 39 patients (Heparin, n = 21 vs Ethanol, n = 18, P = 0.63). it occurred later in ethanol group (Heparin 10.71 ± 1.81 days vs Ethanol 18.65 ± 4.56 days; p < 0.0001); culture positive episodes were 4-Aminobutyrate aminotransferase 8 in ethanol group as compared to 6 in heparin group. The total number of catheter days in situ without CRBSI was more in ethanol group (Heparin 21.14 ± 2.38 days vs Ethanol 28.76 ± 3.51 days; p < 0.0001). No adverse reactions were reported. Conclusion: 70% ethanol as catheter locking solution for 20 minutes prior to initiation of hemodialysis improved catheter survival and delayed the onset of CRBSI. BOON CHEOK LAI1,2,3, LEE YING YEOH2, J RENAUD CLAUDE3 1Boon Cheok; 2Yeoh Lee Ying; 3Claude J Renaud Introduction: Tunneled dialysis catheters (TDC) are widely used for haemodialysis initiation and maintenance, against current practice guideline recommendations which advocate a fistula first approach. Arguments against TDC are more for their long-term than acute complications (ie infections, thrombosis/fibrin sheath, central vein stenosis versus misplacement and vascular/visceral injury) given the low incidence of the latter with mandatory image-guided insertion nowadays.
