Abstract Hemodialysis is accepted as standard therapy for end‐stage renal failure but despite four decades of experience the morbidity and mortality associated with the treatment remains unacceptably high. Quality of dialysis is traditionally measured with reference to urea clearance but it is becoming increasingly apparent that other solutes across the range of molecular size are also important. More prolonged or more frequent therapy may improve dialysis delivery and enhance survival in patients with end‐stage renal disease.

The HEMO study has provided evidence that a higher dialysis dose per session does not improve survival in conventional three times a week hemodialysis (HD). Attention has therefore shifted to HD schedules that vary in frequency and/or duration of dialysis. Although observational data favoring the use of frequent dialysis are steadily accumulating, compelling evidence supporting its superiority is still lacking. Several advances have recently been made with a view to put this form of therapy on much more solid footing. Upcoming research initiatives including clinical trials of frequent HD and the quotidian HD registry will provide a wealth of analytic and descriptive data that will help define the role for frequent HD regimens as a therapy for end-stage renal disease.

Hemodialysis is now routinely provided to more than 300,000 patients in the United States. An epidemic of end-stage renal disease will nearly double this number by 2010. Patients undergoing chronic hemodialysis have high morbidity and mortality rates. Given these facts, most medical providers will be involved in the care of patients undergoing hemodialysis and it is thus important to have an understanding of the dialysis procedure and its attendant risks. This review discusses the basic physiology of the dialysis procedure and its associated complications.

Given the high comorbidity in patients on hemodialysis and the complexity of the dialysis treatment, it is remarkable how rarely a life-threatening complication occurs during dialysis. The low rate of dialysis emergencies can be attributed to numerous safety features in modern dialysis machines; meticulous treatment and testing of the dialysate solution to prevent exposure to trace elements, toxins, and pathogens; adherence to detailed treatment protocols; and extensive training of dialysis staff to handle medical emergencies. Most hemodialysis emergencies can be attributed to human error. A smaller number are due to rare idiosyncratic reactions. In this review, we highlight major emergencies that may occur during hemodialysis treatments, describe their pathogenesis, offer measures to minimize them, and provide specific interventions to prevent catastrophic consequences on the rare occasions when such emergencies arise. These emergencies include dialysis disequilibrium syndrome, venous air embolism, hemolysis, venous needle dislodgement, vascular access hemorrhage, major allergic reactions to the dialyzer or treatment medications, and disruption or contamination of the dialysis water system. Finally, we describe root cause analysis after a dialysis emergency has occurred to prevent a future recurrence.

Hemodialysis is a commonly used therapy for renal failure in critically ill patients. This article reviews components of the hemodialysis system, including vascular access, and provides an explanation of principles underlying the hemodialysis process. Expected patient responses and potential complications of hemodialysis therapy are emphasized. Critical care nursing interventions for the care of patients before, during, and after dialysis also are outlined

Registry or national dialysis data show that a sizeable proportion of contemporary dialysis patients have substantial levels of residual kidney function especially upon transitioning to dialysis therapy. However, among incident hemodialysis patients, the prevailing paradigm has been to initiate "full-dose" triweekly treatment schedules irrespective of native kidney function in most developed countries. Recognizing the benefits of residual kidney function upon the health and survival of dialysis patients, there has been growing interest in incremental hemodialysis, in which dialysis frequency and dose are tailored according to the degree of patients' residual kidney function. Infrequent hemodialysis can also be used for those who prefer a more conservative approach in managing uremia. Clinical practice guidelines support the use of twice-weekly hemodialysis among patients with adequate residual kidney function (renal urea clearance >3 mL/min/1.73 m2), and a growing body of evidence indicates that incremental hemodialysis is associated with better preservation of residual kidney function without adversely impacting survival. Nonetheless, incremental hemodialysis remains an underutilized approach in this population. In this review, we will discuss the history of the twice- versus triweekly hemodialysis schedules; current clinical practice guidelines regarding infrequent hemodialysis; emerging data on incremental treatment regimens and outcomes; and guidelines for the practical implementation of incremental and infrequent hemodialysis in the clinical setting.

End-stage renal disease (ESRD) is a major cause of morbidity and mortality worldwide. Survival of ESRD patients depends on renal replacement therapies, such as kidney transplantation and dialysis. Due to the shortage of potential kidney donors and patients' comorbidities, dialysis is the major therapeutic option offered to such patients. In this review, recent advances in hemodialysis and hemodiafiltration, and their potential impact on improving patient survival will be discussed.

Objective:To analyze the complications of maintaining hemodialysis to improve the survival rate.Methods:50 cases of maintaining hemodialysis in our hospital were selected and their common complications were analyzed.Results:Common complications were hypertension,enlarged heart,low blood pressure,arrhythmia,nausea,vomiting,chest infection and heart failure.Conclusion:In the patients with long-term hemodialysis,the survival rate is reduced because of various complications.But the complications can be effectively controlled by active prevention and full dialysis.
