Hemodialysis is essential treatment for the chronic renal failure patient's long-term cure and for the patient management before and after kidney transplantation. It sustains the endstage renal failure patient's life which didn't get well despite strict regimen and furthermore it becomes an essential treatment to maintain civil life. Bursing implementation in hemodialysis may affect the significant effect on patient's life. The purpose of this study was to obtain the basic data to solve the hypotension problem encountable to patient and the blood loss problem affecting hemodialysis patient'a anemic states by incomplete rinsing of blood in coil through all process of hemodialysis. The subjects for this study were 44 patients treated hemodialysis 691 times in the hemodialysis unit, The .data was collected at Gang Nam 51. Mary's Hospital from January 1, 1981 to April 30, 1981 by using the direct observation method and the clinical laboratory test for laboratory data and body weight and was analysed by the use of analysis of Chi-square, t-test and anlysis of varience. The results obtained an follows; A. On clinical laboratory data and other data by dialysis Procedure. The average initial body weight was 2.37 ± 0.97kg, and average body weight after every dialysis was 2.33 ± 0.9kg. The subject's average hemoglobin was 7.05±1.93gm/dl and average hematocrit was 20.84± 3.82%. Average initial blood pressure was 174.03±23,75mmHg and after dialysis was 158.45±25.08mmHg. The subject's average blood ion due to blood sample for laboratory data was 32.78±13.49cc/ month. The subject's average blood replacement for blood complementation was 1.31 ±0.88 pint/ month for every patient. B. On the hypotensive state and the coping approaches occurrence rate of hypotension was 28.08%. It was 194 cases among 691 times. 1. In degrees of initial blood pressure, the most 36.6% was in the group of 150-179mmHg, and in degrees of hypotension during dialysis, the most 28.9% in the group of 40-50mmHg, especially if the initial blood pressure was under 180mmHg, 59.8% clinical symptoms appeared in the group of“above 20mmHg of hypotension”. If initial blood pressure was above 180mmHg, 34.2% of clinical symptoms were appeared in the group of“above 40mmHg of hypotension”. These tendencies showed the higher initial blood pressure and the stronger degree of hypotension, these results showed statistically singificant differences. (P=0.0000) 2. Of the occuring times of hypotension,“after 3 hrs”were 29.4%, the longer the dialyzing procedure, the stronger degree of hypotension ann these showed statistically significant differences. (P=0.0142). 3. Of the dispersion of symptoms observed, sweat and flush were 43.3%, and Yawning, and dizziness 37.6%. These were the important symptoms implying hypotension during hemodialysis accordingly. Strages of procedures in coping with hypotension were as follows ; 45.9% were recovered by reducing the blood flow rate from 200cc/min to 1 00cc/min, and by reducing venous pressure to 0-30mmHg. 33.51% were recovered by controling (adjusting) blood flow rate and by infusion of 300cc of 0,9% Normal saline. 4.1% were recovered by infusion of over 300cc of 0.9% normal saline. 3.6% by substituting Nor-epinephiine, 5.7% by substituting blood transfusion, and 7,2% by substituting Albumin were recovered. And the stronger the degree of symptoms observed in hypotention, the more the treatments required for recovery and these showed statistically significant differences (P=0.0000). C. On the effects of the changes of blood pressure and osmolality by albumin and hemofiltration. 1. Changes of blood pressure in the group which didn't required treatment in hypotension and the group required treatment, were averaged 21.5mmHg and 44.82mmHg. So the difference in the latter was bigger than the former and these showed statistically significant difference (P=0.002). On the changes of osmolality, average mean were 12.65mOsm, and 17.57mOsm. So the difference was bigger in the latter than in the former but these not showed statistically significance (P=0.323). 2. Changes of blood pressure in the group infused albumin and in the group didn't required treatment in hypotension, were averaged 30mmHg and 21.5mmHg. So there was no significant differences and it showed no statistical significance (P=0.503). Changes of osmolality were averaged 5.63mOsm and 12.65mOsm. So the difference was smaller in the former but these was no stitistical significance (P=0.287). Changes of blood pressure in the group infused Albumin and in the group required treatment in hypotension were averaged 30mmHg and 44.82mmHg. So the difference was smaller in the former but there is no significant difference (P=0.061). Changes of osmolality were averaged 8.63mOsm, and 17.59mOsm. So the difference were smaller in the former but these not showed statistically significance (P=0.093). 3. Changes of blood pressure in the group iutplemented hemofiltration and in the Uoup didn't required treatment in hypotension were averaged 22mmHg and 21.5mmHg. So there was no significant differences and also these showed no statistical significance (P=0.320). Changes of osmolality were averaged 0.4mOsm and 12.65mOsm. So the difference was smaller in the former but these not showed statistical significance（P=0.199). Changes of blood pressure in the group implemented hemofiltration and in the group required treatment in hypotension were averaged 22mmHg and 44.82mmHg. So the difference was smatter in the former and these showed statistically significant differences (P=0.035). Changes of osmolality were averaged 0.4mOsm and 17.59mOsm. So the difference was smaller in the former but these not showed statistical significance (P=0.086). D. On the changes of body weight, and blood pressure, between the group of hemofiltration and hemodialysis. 1, Changes of body weight in the group implemented hemofiltration and hemodialysis were averaged 3.340 and 3.320. So there was no significant differences and these showed no statistically significant difference, (P=0.185) but standard deviation of body weight averaged in comparison with standard difference of body weight was statistically significant difference (P=0.0000). Change of blood Pressure in the group implemented hemofiltration and hemodialysis were averaged 17.81mmHg and 19.47mmHg. So there was no significant differences and these showed no statistically significant difference (P=0.119), But in comparison with standard deviation about difference of blood pressure was statistically significant difference. (P=0.0000). E. On the blood infusion method in coil after hemodialysis and residual blood losing method in coil. 1, On comparing and analysing Hct of residual blood in coil by factors influencing blood infusion method. Infusion method of saline 200cc reduced residual blood in coil after the quantitative comparison of Saline Occ, 50cc, 100cc, 200cc and the differences showed statistical significance (p < 0.001). Shaking Coil method reduced residual blood in Coil in comparison of Shaking Coil method and Non-Shaking Coil method this showed statistically significant difference (P < 0.05). Adjusting pressure in Coil at OmmHg method reduced residual blood in Coil in comparison of adjusting pressure in Coil at OmmHg and 200mmHg, and this showed statistically significant difference (P < 0.001). 2. Comparing blood infusion method divided into 10 methods in Coil with every factor respectively, there was seldom difference in group of choosing Saline 100cc infusion between Coil at OmmHg. The measured quantity of blood loss was averaged 13.49cc. Shaking Coil method in case of choosing saline 50cc infusion while adjusting pressure in coil at OmmHg was the most effective to reduce residual blood. The measured quantity of blood loss was averaged 15.18cc.

배경: 약물용출 스텐트의 출현으로 관상동맥우회술은 급격하게 위축되고 있으며, 이러한 현상은 관상동맥우회술이 일차적 치료법인 다혈관 관상동맥질환에도 적용되고 있다. 본 연구에서는 약물용출 스텐트의 출현이 관상동맥우회술에 미치는 영향을 분석하고(1단계), 다혈관 관상동맥질환 환자에서 관상동맥우회술과 약물용출 스텐트시술 후 1년 추적 임상 결과를 비교하였다(2단계). 대상 및 방법: 약물용출 스텐트의 출현이 관상동맥우회술에 미치는 영향을 알아보기 위해 본 병원에 약물용출 스텐트가 도입되기 전인 2001년 3월부터 2003년 2월까지 2년간 심폐바이패스를 사용하지 않고 관상동맥 우회술을 시행한 환자(n=298)와, 약물용출 스텐트의 사용이 활발해진 2003년 7월부터 2005년 6월까지 2년간 심폐바이패스를 사용하지 않고 관상동맥우회술을 시행한 환자(n=298)를 비교하였다(1단계). 관상동맥우회술과 약물용출 스텐트시술의 단기 임상 성적을 비교하기 위해, 2003년 3월부터 2004년 6월 사이에 약물용출 스텐트를 시행받은 환자(n=220)와, 약물용출 스텐트 도업 전후 2002년 3월부터 2004년 3월 사이에 관상동맥우회술을 시행받은 환자(n=255)를 대상으로 각각 1년 추적 관찰 후, 심근 경색의 발생, 심장 관련 사망의 빈도, 표적혈관 재관류율 등에 대하여 비교하였다(2단계). 결과: 약물용출 스텐트의 도입 이후, 경피적 관상동맥중재술 대비 관상동맥우회술의 비율이 감소하였으며, 관상동맥우회술군에서 대상 환자들의 고령화(62세 vs. 64세, p=0.023), 만성신부전 (4% vs 9%, p=0.021), 상행대동맥의 석회화 (9% vs. 15%, p=0.043) 등을 동반한 고위험군의 환자 빈도의 증가, 그리고 준응급 및 응급수술의 빈도(12% vs. 22%, p=0.002)가 증가 등이 관찰되었다. 하지만 이전과 비교하였을 때 수술 관련 사망 및 문합부위의 개존률에는 변화가 없었다(1단계). 1년 추적 기간 중 표적혈관 재관류율은 약물용출 스텐트시술 후가 관상동맥우회술보다 높았으며(12.3% vs. 2.4%, p<0.001), 이로 인하여 주요 심장사건(사망, 심근경색, 표적혈관 재관류율) 역시 약물용출 스텐트시술 후가 관상동맥우회술보다 증가하였다(13.6% vs. 4.3%, p<0.001). 하지만 표적혈관 재관류율을 제외 한 심장 관련 사망 및 섬근 경색의 빈도는 각각 1달과 1년 추적 결과 두 군간의 유의한 차이를 보이 지 않았다(2단계). 결론: 약물용출 스텐트의 출현 이후 관상동맥우회술을 시행받는 환자들의 동반질환 빈도가 증가하였다. 단기 추적 관찰 결과, 약물용출 스텐트의 시술 후 표적혈관 재관류율이 증가하였으며, 주요 심장사건의 발생이 증가하였으나, 심근 경색의 발생 및 사망률은 관상동맥우회술과 비슷한 조기 임상결과를 보였다.
