Some dialysis units have a policy of performing cardiopulmonary resuscitation (CPR) on all patients who experience cardiac arrest while undergoing dialysis. However, to perform CPR on patients who do not want it is contrary to ethics and the law. We interviewed hemodialysis patients in 12 units in Missouri, New York, and West Virginia to learn their attitudes about CPR. ⋯ We conclude that most dialysis patients want to undergo CPR, but also want other patients' preferences not to be resuscitated to be respected. Dialysis units need to do a better job of identifying patients who prefer not to be resuscitated and respecting their wishes in the event of cardiac arrest while undergoing dialysis. Most importantly, nephrologists and dialysis unit staff need to educate dialysis patients about the poor outcomes with CPR so that dialysis patients' decisions about CPR are informed.

Randomized Controlled Trial Multicenter Study Clinical Trial
Atrial natriuretic factor in oliguric acute renal failure. Anaritide Acute Renal Failure Study Group.
Atrial natriuretic peptide (ANP), an endogenous hormone synthesized by the cardiac atria, has been shown to improve renal function in multiple animal models of acute renal failure. In a recent multicenter clinical trial of 504 patients with acute tubular necrosis (oliguric and nonoliguric), ANP decreased the need for dialysis only in the oliguric patients. In the present study, 222 patients with oliguric acute renal failure were enrolled into a multicenter, randomized, double-blind, placebo-controlled trial designed to assess prospectively the safety and efficacy of ANP compared with placebo. ⋯ One hundred two of 108 (95%) versus 63 of 114 (55%) patients in the ANP and placebo groups had systolic blood pressures less than 90 mm Hg during the study-drug infusion (P < 0.001). The maximal absolute decrease in systolic blood pressure was significantly greater in the anaritide group than placebo group (33.6 versus 23.9 mm Hg; P < 0.001). This well-characterized population with oliguric acute renal failure had an overall high morbidity and mortality.

Randomized Controlled Trial Multicenter Study Clinical Trial
Sodium ferric gluconate complex in sucrose is safe and effective in hemodialysis patients: North American Clinical Trial.
A new intravenous (i.v.) iron compound, sodium ferric gluconate complex in sucrose (Ferrlecit, R&D Laboratories, Inc, Marina Del Rey, CA), was administered over 8 consecutive dialysis days in equally divided doses to a total of either 0.5 or 1.0 g in a controlled, open, multicenter, randomized clinical study of anemic, iron-deficient hemodialysis patients receiving recombinant human erythropoietin (rHuEPO). Effectiveness was assessed by increase in hemoglobin and hematocrit and changes of iron parameters. Results were compared with historically matched controls on oral iron. ⋯ In comparison with 25 matched control patients, adverse events could not be linked to drug therapy, nor was there a dose effect. In conclusion, sodium ferric gluconate complex in sucrose is safe and effective in the management of iron-deficiency anemia in severely iron-deficient and anemic hemodialysis patients receiving rHuEPO. This study confirms the concepts regarding iron therapy expressed in the National Kidney Foundation Dialysis Outcomes Quality Initiative (NKF-DOQI) that hemodialysis patients with serum ferritin below 100 ng/mL or transferrin saturations below 18% need supplementation with parenteral iron in excess of 1.0 g to achieve optimal response in hemoglobin and hematocrit levels.

Effect of a silver device in preventing catheter-related infections in peritoneal dialysis patients: silver ring prophylaxis at the catheter exit study.
Catheter-related infections remain a significant cause of method failure in chronic peritoneal dialysis (PD) therapy. Given the increasing antibiotic resistance, such nonpharmacological strategies as local silver devices attract more interest. To establish whether a silver ring device (designed by Grosse-Siestrup in 1992) mounted onto the PD catheter and placed at the exit site at skin level is effective in preventing exit-site and other catheter-related infections, a prospective 12-month, multicenter, controlled study stratified by diabetes status was conducted. ⋯ Univariate analysis and multiple logistic regression identified younger age (<50 years), low serum albumin level (<35 g/L), number of previously placed PD catheters, short cuff-exit distance (<2 cm), and S aureus nasal carriage as risk factors for the development of exit-site infections. In conclusion, our study does not show any benefit of the silver ring in preventing catheter-related infections in PD patients. Thus, prevention of infection-related method failure in PD still has to rely on conventional antibiotic treatment strategies and less so on alternative methods.

Multicenter Study
Quality of life in patients on chronic dialysis: self-assessment 3 months after the start of treatment. The Necosad Study Group.
The aim of the present multicenter study was to assess quality of life of Dutch dialysis patients 3 months after the start of chronic dialysis treatment. The quality of life was compared with the quality of life of a general population sample, and the impact of demographic, clinical, renal function, and dialysis characteristics on patients' quality of life was studied. New end-stage renal disease (ESRD) patients who were started on chronic hemodialysis or peritoneal dialysis in 13 dialysis centers in The Netherlands were consecutively included. ⋯ Comorbid conditions, hemoglobin, and residual renal function could explain poor quality of life only to a limited extent. Further research exploring determinants and indices of quality of life in ESRD patients is warranted. From a clinical perspective, we may conclude that quality of life should be considered in the monitoring of dialysis patients.
