Dialyzer re-use--a multiple crossover study with random allocation to order of treatment.

A multiple crossover research study was used to evaluate the effect of dialyzer re-use on fever, blood leaks, serum urea and creatinine values and symptoms. Each of 6 crossover periods consisted of 4 weeks on either single-use or re-use, 1 week washout, 4 weeks on the alternative treatment and 1 week washout. The re-use consisted of 6 uses of each dialyzer and the washout weeks consisted of 3 single-use sessions. Analysis of paired observations within rather than between patients showed no effects of time (i.e. among crossover periods 1 through 6) or number of re-uses (i.e. among uses 1 through 6). There was no significant difference for temperature change during dialysis, blood leak rate, or the serum urea and creatinine values before the first dialysis of each washout period. There were no differences for symptoms of pruritus, cramps, nausea, headache, chest pain, backache or fatigue. There were no clinical advantages or disadvantages associated with dialyzer re-use.

Self-recording of blood pressure in the management of hypertension.

The efficacy of self-recording of blood pressure in the management of hypertension was assessed in a randomized clinical trial involving 140 persons who had been receiving antihypertensive therapy for a year or more, but whose diastolic blood pressure had remained at 95 mm Hg or higher. To control for the increased attention implicit in self-recording, which might affect blood pressure, the patients were assigned at random to one of the four groups: self-recording and monthly home visits, self-recording only, monthly home visits only, and neither self-recording nor monthly home visits. This design also permitted assessment of the effect of home visits. During the 6-month experiment no significant differences were apparent between the groups in either compliance or diastolic blood pressure. However, both self-recording and monthly home visits produced a reduction in blood pressure among patients who admitted to difficulty remembering to take their pills; a reduction was not seen among patients who said they had no such difficulty. This confirmed an earlier observation suggesting that this easily identified group of patients may be the most responsive to intervention programs.

Spontaneous perirenal hemorrhage in patients on hemodialysis.

Spontaneous perirenal hemorrhage is a rare complication in patients on hemodialysis. Two cases of this condition are described. The diagnosis was confirmed by selective renal arteriogram, and exploration and nephrectomy was the treatment of choice.

Chronic hemodialysis for terminal renal failure.

Ten terminal uremic patients seen over the period of one and one-half years have been kept alive by repeated hemodialysis using a modification of the Seattle system, carried out for the most part by nurses and technicians. All the patients had creatinine clearance values below 5 ml./min., and blood urea nitrogen values which ranged between 156 and 453 mg. % before beginning the first dialysis.Selection was based on their ability to co-operate with and to tolerate the regimen. Nine patients were fully rehabilitated.The major complications were those related to shunt-site infections, including septicemia, bacterial endocarditis, septic arthritis, septic pulmonary embolism and mycotic aneurysm.Nevertheless, all patients except one were rehabilitated and resumed their full-time occupations and have continued to lead happy and useful lives.
