Purpose: The purpose of this study is to identify the effect of low sodium dialysate (LSD) rather than conventional dialysate on interdialytic weight gain (IWG), blood pressure (BP), and intradialytic side-effects (ISEs) in patients on maintenance hemodialysis (HD). Methods: The study was performed in 43 patients, who were treated in the university hospital over 8 weeks. Each participant's serum sodium set point was measured using dialysate sodium 140 mEq/L during the first 4 weeks. For the next 4 weeks dialysate sodium concentrate (134,136,and138 mEq/L) was provided to each participant but only to an experimental group (EG) (n=22) based on the individual set point, although 140 mEq/L dialysate was given to all of the control group (CG) (n=21). Consequently, outcomes including IWG, BP, and ISE were evaluated. Results: In EG, difference of pre-HD SBP (p=.047) and post-HD serum sodium (p=.006) were significantly decreased compared to CG. Also, ISEs was not more frequent in EG. However, the differences were not statistically significant, IWG (kg & %), pre-HD DBP, post-HD SBP & DBP, and serum osmolality in EG. Conclusion: Individual application of LSD in patients on maintenance hemodialysis is beneficial to decrease pre-HD SBP and post-HD serum sodium without increasing ISE. Therefore, LSD can be better treatment than conventional dialysate.

Purpose: The purpose of this paper was to identify blood pressure, interdialytic weight gain, thirst and intradialytic discomfort in subjects after applying individual low-sodium dialysis fluid (1,2,3 mEq/L) to hemodialysis patients for 12 weeks. Methods: This study was a non-equivalent pre-post design. For 12 weeks, dialysate concentration was maintained at 1 mEq/L or 2 mEq/L or 3 mEq/L based on average sodium concentration of each individual, and the difference was compared after applying individually. Results: Change in blood pressure significantly decreased in the group where in pre-hemodialysis systolic pressure decreased the gradient of sodium concentration in serum sodium and dialysis solution by 2mEq/L. Interdialytic weight gain, and thirst showed significant decrease in all three groups. But in all three groups, intradialytic discomfort among dialysis showed no significant changes. Conclusion: Although application of low sodium dialysis fluid showed no change in intradialytic discomfort, lowered blood pressure, thirst, and interdialytic weight gain, which could be used for individual showing increased interdialytic weight gain and increased blood pressure. There is need for continued study on this.

신생아나 영아의 급성신부전증의 치료를 위하여서 복막투석이 매우 유효한 방법으로 알려져 있지만 혈역학적으로 불안정한 상태에서 저용량, 고농도의 투석액으로 자주 교환하는 방법이 통상적인 투석방법과 마찬가지로 효율적인지를 알아보기 위하여 본 연구를 시도하였다. 대상환아는 신생아와 영유아에서 혈역학적으로 불안정하리라 추정되는 7례의 급성신부전증 환아를 대상으로 저용량($14.2{\pm}4.2ml/kg$), 고농도(4.25% dextrose)의 투석액을 30-45분의 짧은 간격으로 교환하는 복막투석을 실시하여 통상적인 방법을 사용한 4례의 환아와 비교하였다. 환아의 연령은 $1.9{\pm}1.3$개월이었고, 체중은 $4.6{\pm}1.6kg$이었으며 신부전증을 일으킨 원인은 패혈증과 이에 동반한 쇽 5례와 심장수술 후 과다혈량 상태가 생긴 2례였다. 도관은 경피적으로 pigtail 도관이나 Tenckhoff 도관을 삽입하였다. 유효한외과여과율은 $0.27{\pm}0.09ml/min$로서 통상적인 방법에 의한 $0.29{\pm}0.09ml/min$와 유의한 차이가 없었다. 또한 투석 24시간 후 혈중 BUN은 $95.6{\pm}37.5mg/dl$에서 $ 75.7{\pm}25.9mg/dl$로 감소하였고, 혈중 pH는 $7.122{\pm}0.048$에서 $7.326{\pm}0.063$으로 증가하였다. 투석중의 부작용으로는 2례의 고혈당증, 2례의 도관 주위 누출, 1례의 경한 저나트륨혈증과 1례의 복막염이 발생하였으나 비교적 용이하게 교정이 가능하였다. 이들 환아중 2례의 환아가 선행질환의 악화로 사망하였다.

Hemodialysis(HD)-associated hypotension is a frequent complication, but it is difficult to manage. Until now, several maneuvers have been tried to prevent the HD-associated hypotension. Of these, the sodium content of dialysate was regarded as an important factor for maintaining blood pressure during HD. In this study, we evaluated the effect of hypertonic dialysate on blood pressure, interdialytic weight gain and the incidence of thirst. The study was done for 6 weeks successively with 3 different groups. Each patient was dialysed with 3 different dialysates for 2 weeks: Group I(Conventional HD: sodium concentration: 137 mEq/L), Group II(Hypertonic HD: 147 mEq/L) and Group III (Sequential HD: from 147 to 140 mEq/L). Hemodynamic parameters(blood pressure, pulse rate and ultrafiltration rate), biochemical parameters(hematocrits, blood urea nitrogen, creatinine, osmolality, sodium, potassium, chloride, fasting blood sugar) and complications (interdialytic weight gain & thirsty sensation) were compared among 3 groups. The results were as follows: 1. Decline of systolic blood pressure and diastolic blood pressure at the time of a 3 hour check during hemodialysis was lower in the Group II than Group I and III (p=0.002; p=0.012). and decline of diastolic blood pressure at the time of a 4 hour check during hemodialysis was lower in the Group II and III than Group I (p=0.04). 2. Incidence of hypotensive episodes during dialysis was significantly lower in Group II than group I (p=0.0287). 3. The ultrafiltration in Group III at the time of 1 hour, 2 hour and 3 hour check during hemodialysis was higher than that in Group I and II at the time of 1 hour, 2 hour and 3 hour check during hemodialysis respectively (p=0.0001; p=0.0001; p=0.0004). 4. Interdialytic weight gain was higher in Group I($3.1{\pm}0.8$) than Group I($2.8{\pm}0.8$) and III ($2.9{\pm}0.9$) (p=0.0422). 5. Hematologic and biochemical results were not significantly different among 3 Groups. 6. Frequency of thirst was different in Group I, II and III, $0.05{\pm}0.12$, $0.41{\pm}0.24$and $0.22{\pm}0.29$ respectively (p=0.0259). The results suggest that hypertonic HD was effective in preventing HD-associated hypotension but interdialytic weight gain and thirst sensations were increased as compared with a conventional method. In this situation, sequential HD seems to be an alternative method to minimizes the side effect of hypertonic HD.
