ABSORPTION OF BLOOD FROM THE PERITONEAL CAVITY OF THE DOG

Abstract

Normal and protein-depleted dogs were subjected under Na pentobarbital anesthesia to a single nonfatal hemorrhage, and in some cases the withdrawn blood was transferred directly into the peritoneal cavity. Observations made before and 24 hrs. after hemorrhage revealed that: (1) In both normal and hypoproteinemic dogs the absorbed blood contributed in part to the restoration of the plasma proteins and to the plasma protein reserves. (2) The absorption of the blood did not result in the restoration of the circulating hemoglobin and red cell volume in normal dogs, whereas in the case of the similarly treated hypoproteinemic dogs there was some degree of restoration of hemoglobin and erythrocyte volume. During a 6-day interval following the absorption of blood no change was observed in the urine total N excretion.
