title: [Osmolar and free water clearance as renal function test during extracorporeal circulation with parcial and total hemodilution (author's transl)].
abstract: Four groups of dogs are subjected to extracorporeal circulation. Total hemodilution is used in groups I and II, either in normothermia or moderate hypothermia at 30 degrees C. Partial hemodilution is used in groups III and IV with identical temperature variations. The animals are kept under extracorporeal circulation for 120 min. Osmolar and free water clearance are measured at basal conditions after 40, 80 and 120 min. The present results show that total hemodilution should be used in those patients subjected to extracorporeal circulation where renal function has been previously disturbed.
