  • This study is to define the hemodiafiltration treatment compliance indicators and discriminate standards for hemodiafiltration patients and development of hemodiafiltration treatment compliance measurement-convergent form. Date was collected from 300 on-line hemodiafiltration patients. To verify the hemodiafiltration treatment compliance indicators and discriminate standards, used construct validity and content validity by clinical professional group. Discriminant ability of 3 indicators-interdialysis weight gain rate(IWGR), serum phosphate level, rate of self change of total hemodiafiltration treatment time(SCR-HEFTT)- is 95.6%(wilks ramda=.256, p=.002). And hemodiafiltration treatment compliance measurement-convergent form has 91.7% discriminant accuracy. Hemodiafiltration treatment compliance is important that nurses can aware pre-stage of complication and give appropriate nursing intervention. Also this measurement can be used for foundation data of the nursing intervention development that prevent dialysis patient's complication.

  • Acute hyperammonemia is a medical emergency in the newborn. Efficient, prompt removal of serum ammonia is essential in preventing irreversible brain damage in order to prevent the profound central nervous system dysfunction due to hyperammonia. We report a case of 2.3 kg, 5-day old girl with methylmalonic acidemia who presented with severe hyperammonemia and was successfully treated with continuous venovenous hemodiafiltration(CVVHDF). CVVHDF is an effective and safe method of ammonia removal in the newborn.

  • Conventional high-flux hemodialysis (HD) is not as good as normal kidney function. Morbidity and mortality rates of patients receiving HD are still very high. To increase mid-to-large molecule clearance by combining diffusion and convection, on-line hemodiafiltration (HDF) is required. The objective of this study was to compare long-term survival rate of patients treated with on-line HDF to those who received conventional high-flux HD by reviewing data from Chonnam National University Hospital (CNUH). We selected patients who attended the 'CUNH dialysis center' and agreed to participate in the study. Overall, 40 patients with ESRD switched from high flux HD to on-line HDF or started on-line HDF from August 2007 to December 2009. Additionally, a total of 42 patients receiving conventional high-flux HD during the same period were enrolled. We then reviewed long-term survival rate of patients receiving on-line HDF over the next seven years. When we compared survival rates for seven years, the survival rate of the group receiving on-line HDF was 65% (26/40) while that of the group receiving the conventional high-flux HD was 54.8% (23/42). Although the number of patients was small to see survival difference clearly by one specific dialysis modality, there was somewhat difference in survival rate between the two groups. Indicators such as anemia, calcium-phosphate metabolism, nutritional status, treatment adequacy, and hospitalization were also improved in the group receiving HDF. Overall, results of our study showed beneficial effects of on-line HDF on clinical outcomes and survival in chronic HD patients.

  • Using numerical models, we investigated the efficiency of toxin removal using pulsatile flow in blood purification systems that use semipermeable membranes. The model consisted of a three-compartmental mass transfer model for the inside body and a solute kinetics model for the dialyzer. The model predicted the toxin concentration inside the body during blood purification therapy, and the toxin removal efficiencies at different flow configurations were compared quantitatively. According to the simulation results, the clearances of urea and ${\beta}_2$ microglobulin (B2M) using a pulsatile pump were improved by up to 30.9% for hemofiltration, with a 2.0% higher urea clearance and 4.6% higher B2M clearance for high flux dialysis, and a 3.9% higher urea clearance and 8.2% higher B2M clearance for hemodiafiltration. These results suggest that using a pulsatile blood pump in blood purification systems with a semipermeable membrane improves the efficacy of toxin removal, especially for large molecules and hemofiltration treatment.

  • A 66-year-old male with chronic alcoholism presented with tremor, gait disturbance, memory impairment, insomnia, decreased appetite, and confusion. The patient had been taking lithium daily for treatment of bipolar disorder. Brain CT showed no specific abnormality, and serum lithium and ammonia levels were 3.63 mEq/L (therapeutic range, 0.6~1.2 mEq/L) and $85{\mu}g/dL$ (reference range: $19{\sim}54{\mu}g/dL$), respectively. Therefore, the initial differential diagnosis included chronic lithium intoxication, hepatic encephalopathy, Wernicke encephalopathy, or alcohol withdrawal syndrome. Even with the provision of adequate hydration, the patient's neurologic status did not show improvement, so that lactulose enema, thiamine replacement, and continuous venovenous hemodiafiltration (CVVHDF) were started on the third admission day. By the fifth admission day he had made a rapid neurologic recovery, and was discharged on the 20th admission day. Therefore, CVVHDF might be a treatment for patients with chronic lithium intoxication, because, even if serum lithium concentration is normal, lithium concentration in the brain may be different from that of the serum.

  • Esophagectomy and esophageal reconstruction are commonly chosen as surgical options for esophageal cancer. However, prolonged untreated chyle leakage is associated with a poor prognosis. We report the case of a patient with refractory chylous ascites. To limit the ongoing fluid loss, we utilized the chylous ascites as an additional fluid source in a renal replacement therapy system. A continuous renal replacement therapy (CRRT) drainage system was modified to drain both the chylous ascites and venous blood. The ascites drainage rate was determined empirically and regulated by a dial-flow extension set. The CRRT mode was set to continuous venovenous hemodiafiltration and maintained for 7 days. After the patient was weaned from CRRT, ascites did not reaccumulate, and the patient's general condition improved dramatically. No infections related to the system occurred. This procedure temporarily alleviates symptoms and provides more time for alternative treatment strategies.

  • Purpose: The purpose of this study was to understand nurses' experience of managing diet and fluid in hemodialysis patients and to provide helpful information in improving care of hemodialysis patients. Methods: Data were collected through in-depth interviews with ten nurses who had experience of providing care to hemodialysis patients. Colazzi's phenomenological method was used to analyze data. Results: Twenty themes were identified in the first stage of data analysis and were later categorized into ten theme clusters, of which four categories were derived. The four categories were 'developing a strong feeling of responsibility for management', 'acknowledging limits in performing duties', 'providing patient-centered education' and 'becoming a guide for the long treatment process'. Conclusion: The study results will be useful for improving nursing curriculum to ensure more effective and successful diet and fluid management in hemodialysis patients.
