        출혈위험이 있는 혈액투석 환자간호에서의 Heparin bound method 적용

        설정숙,문지현,심순범,조해숙,안명애,유제복 병원간호사회 1997 임상간호연구 Vol.3 No.1

        The purpose of this research is to determine the effect of the Heparin Bound Method that S-hospital has developed and operated for decreasing a patients bleeding hazard during dialysis. The research consisted of 32 patients of total patients with a bleeding-hazard between May 1, 1996 and Oct. 20, 1996 at S-hospital. Elements of the investigation include : the degree of dialyser clotting, dialysis time, and Kt/V. The collected data was analyzed using statistical methods of average, percentage, and standard diviation. Analysis of variance(ANOVA) was used to determine the difference between dialysis time and the extent of coagulation. Pearson Correlation Coefficients was used to analyze the correlation between dialysis time and the coagulation parameter. The results of this research are as follows : (1) The extent of coagulation on the dialysis membrane averaged 15.1% and 25 of the subjects attained 240 minutes of our target time. (2) Comparing dialysis time with the degree of dialyser clotting, the degree of dialyser clotting averaged 11.7% in the group which attained 240 minutes of our target time and averaged 27% in the other group. Therefore, the acheived group indicated a lower percentage than the total average of 15.1% and the other group indicated a higher one. Consequently, the degree of dialyser clotting has high correlation with dialysis time(p=0.04) (3) In the case of aPTT and ACT based on 0 minutes, 0 minutes has a very high correlation with 2 hours (p=0.009, p=0.0001). (4) The coagulation parameter and the extent of coagulation on the dialysis membrane have weak correlation and there are many other parameters for coagulation in the circulatory path introduced by the dialysis equipment (r=-0.25~-0.44).
