Slow nocturnal home hemodialysis (SNHHD)--one year later.

Abstract

High costs and overcrowding of dialysis centres are leading to a global crisis in health care provision. We are developing slow nocturnal home hemodialysis (SNHHD) in which patients dialyze for eight to 10 hours during sleep five to seven nights per week. Vascular access is by means of the Cook silastic jugular catheter. Special precautions are taken to prevent accidental disconnection and air embolism. Dialysis functions are remotely monitored on computer via a modem by trained staff. Five patients have completed five to seven weeks of training and have been successfully performing SNHHD single-handedly (three out of five patients live alone) for 14, 14, 11, 10 and four months respectively. All have discontinued their phosphate binders and increased dietary phosphate intake. Compared with conventional hemodialysis (CHD) results, average pre-dialysis urea and creatinine levels are remarkably reduced to 9.6 mmol/l and 486 umol/l respectively. The average cumulative weekly Kt/V for CHD is 5.0 as compared to 7.7 while on SNHHD. Four out of five patients report sleeping soundly and experience greatly increased energy and stamina. Their days are entirely free. Repeated in-situ re-use of the dialyzer and blood lines will reduce the patient's work and make SNHHD a very inexpensive modality. SNHHD appears to be a widely applicable treatment with many advantages to both the patient and the health care system.
