The physiology of peritoneal solute transport and ultrafiltration

摘要: Few studies have been published on the magnitude of surface area peritoneum. Wegener mentioned a 1.72 m2 in one adult woman [1] and Putiloff value 2.07 male [2]. More recent autopsy reported lower values [3–5]; average peritoneal adults ranged from 1.0 [3] to 1.3 [5]. Using CT scanning CAPD patients 0.55 has found [6], but this method needs further validation. Some relationships between body weight and/or area, while others did not. The ratio is about half that newborn infants [3]. A difference barely present when related [3].The peritoneal/body averaged 0.6–0.8 adults, 0.5–0.6 infants. About 60% peritoneum consists visceral peritoneum, 10% which covers liver, 30% mesenterium omentum, parietal [3–5]. latter includes diaphragmatic comprises 3–8% total area. Species differences are present, especially with regard contribution larger humans than rodents various parts solute transport during dialysis may vary. Evisceration was cause marked reduction creatinine rabbits [7], not rats [8, 9]. Effective described neonate extensive resection small intestine [10]. It hypothesized covering liver might be important dialysis, because close proximity sinusoids, could confirmed experimental [11, 12]. part involved absorption solutes fluid cavity into lymphatic system [13]. Observations shown increases age animals, proportional increase dialysate/plasma (D/P) ratios urea [14].
