Effectiveness of a phosphorous educational program for dialysis patients.

Fifty-four percent of all dialysis patients followed by a single center had elevated serum phosphorus levels on more than 25% of all measurements. A phosphorus patient education program was developed and implemented and knowledge was measured with a pretest and posttest. The continuous ambulatory peritoneal dialysis group had a significant increase in knowledge and a minor, but statistically significant, decrease in serum phosphorus after participating in the education program. In contrast, center hemodialysis patients did not demonstrate a significant increase in knowledge or decrease in serum phosphorus. These different outcomes could not be attributed to specific differences between the two groups. Serum phosphorus control is a complex process, and this education program did not result in a clinically significant improvement in serum phosphorus levels.

Peritoneal dialysis transfer set change procedures study.

The purpose of this in vitro study was to evaluate the effectiveness of continuous ambulatory peritoneal dialysis (CAPD) procedures. Four procedures to disinfect the catheter adapter/transfer set connection were compared in vitro using a mock sterile CAPD system.

Intraabdominal pressures during natural activities in patients treated with continuous ambulatory peritoneal dialysis.

Intraabdominal pressures were measured during natural activities in 6 men, age 24-62 years, treated with continuous ambulatory peritoneal dialysis. The pressures were measured with a pressure transducer secured at the level of the umbilicus in the supine, sitting, and upright positions with 0-3 liters intraperitoneal fluid during talking, coughing, straining, changing position, walking, jogging, exercycling, jumping and weight lifting. Coughing and straining generated the highest intraabdominal pressures in every position. The pressures with weight lifting were proportional to the magnitude of the weight lifted up to 50 lbs, but were lower than those during coughing and straining. The pressures were generally higher with greater intraabdominal fluid volumes, especially with jumping and coughing. Exercycling was associated with lower intraabdominal pressure than was jogging, and the pressures were only minimally influenced by intraperitoneal fluid volumes. The results of this study can be used as a guide in establishing preventive measures in patients with intraperitoneal fluid to decrease complication rates related to raised intraabdominal pressures such as dialysate leaks, hernias and hemorrhoids.
