    Abstract:
    Effective peritoneal capillary blood flow (EPBF) was evaluated by calculation of diffusive mass transport coefficient of CO2 during intermittent peritoneal dialysis performed with intraperitoneal administration of sodium nitroprusside (NP, 5 mg/l of dialysis solution) or chlorpromazine (Cl-Prom, 2.5 mg/l of dialysis solution). Peritoneal transfer rates of substances of different molecular size and charge were simultaneously examined and compared with EPBF. During NP or Cl-Prom administration, EPBF was respectively 220 +/- 40 (n = 11) and 224 +/- 29 (n = 10) ml/min. These values were insignificantly higher than those obtained during dialyses without drugs (169 +/- 16 ml/min, n = 10). NP and Cl-Prom did not cause any significant changes in peritoneal transfer of CO2. Transfer rates of HCO3 and tCO2 were increased only with NP. Both drugs enhanced peritoneal removal of Na+, K+, urea, uric acid and total protein, but with similar EPBF during the use of both drugs, the effect of NP was more pronounced. The obtained results indicate that EPBF is not a major factor responsible for enhanced peritoneal transfer rates during dialyses performed with NP or Cl-Prom.
