N/A Arteriovenous fistula(AVF) has been the most important, primary mode of achieving vascular access for chronic hemodialysis by this time. In general, maturation period over 4 to 8 weeks after operation for the formation of AVF has been recommended for the long-term survival of AVF, and so insertion of central venous catheter without using AVF being matured has been primarily recommended whenever hemodialysis is needed. But not infrequently, serious complications have been reported in association with the insertion and the use of central venous catheter. So earlier use of AVF is regarded as a good method of avoiding serious complications with regard to the insertion and the use of central venous catheter. But early use of AVF has not been generally recommended, for early use of AVF has been regarded to be associated with early failure of AVF. But few studies have reported the correlation between maturation period and AVF survival. And in practice, early use of AVF has already been performed frequently by not a few nephrologists or nurses of dialysis units. So authors tried to examine the correlation between maturation period and AVF survival rate, and to find the validity of early use of AVF if it is regarded usable for the hemodialysis by experienced hemodialysis nurses and nephrologists. Methods : A retrospective analysis using 88 AVF cases which had been created in 85 patients from Oct. 1986 through June 1996, and from which authors could get enough information for this study was done. Authors compared one year survival rates of AVF according to the maturation period, the presence of DM, and condition of AVF assessed clinically by doctors and experienced nurses in hemodialysis units. Also from the cases with AVF obstruction, authors examined the 1st, 2nd, and 3rd year survival rate of AVF according to the maturation period. Results : One year survival rate of AVF with maturation period less than 4 weeks was higher than that with maturation period more than 4 weeks, but there was no statistical significance. One year survival rate, irrespective of the length of maturation period for AVFs, of AVF regarded to be usable and good for hemodialysis was higher than that of AVF regarded to be usable but not good for hemodialysis. In the study with the AVF obstruction group only, one year survival rate of AVF with maturation period less than 4 weeks was higher than that of AVF with maturation period more than 4 weeks but there was no statistical significance. And one year AVF survival rate was higher in non DM group(94.1%) than DM group(60%) regardless of maturation period of AVF(P<0.05). Conclusion : On the contrary to the views that longer maturation period of more than 4 weeks will be necessary for the long-term survival of AVF, our results suggest that shorter maturation period for AVF less than 4 weeks does not necessarily mean early failure of AVF once AVF is regarded to be usable for hemodialysis. So it is suggested that early use of AVF instead of inserting central venous catheter is a reasonable approach for getting an adequate vascular access for hemodialysis in chronic renal failure patients who were subjected to receive hemodialysis on waiting peroid of AVF maturation.

혈액투석중인 만성신부전 환자에서 혈압조절의 양상과 투석적절도가 혈압에 미치는 영향

N/A Objective : Volume expansion has been known to be the major factor in the development of hypertenision in chronic hemodialysis(HD) patients. But some HD patients remain hypertensive even with adequate volume control, which suggests the role of undefined uremic toxin in the pathogenesis of hypertension. So we aimed to evaluate the status of blood pressure (BP) control and the effect of Kt/V (as a marker for removal of uremic toxin) on BP in chronic HD patients. Methods : The status of BP control was obtained from records of 8 HD session in 132 patients in November 1996 and 127 patients in November 1997. Of 132 patients studied in 1996, 70 patients underwent a follow-up evaluation in 1997. All patients were dialyzed 3 times a week, 4 hours a session. Postdialytic cyclic 3',5' guanosine monophosphate (cGMP) level was measured in 48 patients as a marker of volume status. Results : The prevalence of postdialytic hypertension (>140/90mmHg) was 73.5 in 1996 and 65.3% in 1997. Normotensive patients (postdialytic mean BP <114 mmHg) had higher Kt/V value than hypertensive patients in both 1996 and 1997. But there was no difference in the degree of ultrafiltration (UF) and cGMP level between two groups. Postdialytic mean BP was inversely correlated with Kt/V level but had no relationship with degree of UF and cGMP level in both 1996 and 1997. The group in which postdialytic mean BP had been decreased during 1 year study period had higher degree of elevation in Kt/V than the group in which postdialytic mean BP had been increased. The changes of postdialytic weight and degree of UF during study period were similar between two groups. The number of antihypertensives used were also inversely correlated with Kt/V but not correlated with degree of UF and cGMP level in both 1996 and 1997. Conclusion : Our study indicate that increasing HD adequacy is associated with improved control of postdialytic mean BP and less use of antihypertensive drugs. UF and antihypertensive drugs may not be adequate form of hypertension treatment as once thought and increasing HD adequacy can be an alternative method.
