[Effects of nitroprusside and vibration on peritoneal transport of solutes in continuous ambulatory peritoneal dialysis patients].
To explore the relationship between peritoneal transport of solutes and permeability of the peritoneum capillary as well as peritoneal stagnant fluid layer within dwell time, we observed the effects of nitroprusside and vibration on peritoneal transport of solutes in continuous ambulatory peritoneal dialysis(CAPD) patients. Twelve stable, routine CAPD patients were involved, who had no peritonitis for at least 4 weeks before the test. Standard peritoneal equilibrium tests(PETs) were performed, and mass transfer area coefficiency(MTAC) were calculated after adding nitroprusside to the dialysate or vibrating the patients's peritoneum. The concentrations of total protein, albumin and immunity globulin G in total drained dialysate were examined, and total drained volumes were recorded. Compared with the control, the MTACs value of BUN, Creatinine(Cr) increased significantly both in the nitroprusside group and vibration group(P < 0.05); the concentration of immunoglobin G in the total drained fluid was higher in the nitroprusside group than that in the control(P < 0.05); However, there was no significant difference in the total drained volume among the three groups. We conclude that nitroprusside and vibration can increase the peritoneal transport of small molecular solutes, and vibration has less influence on the loss of protein in CAPD. It suggests that moderated movement may improve the removal of the small molecules in CAPD patients.
