Influence of the plasmapheresis uses in the recovery time of blood or plasma donor goats

Abstract

The objective of this study was to determine the influence of plasmapheresis on clinical and haematological recovery time of whole blood or plasma donor goats. For this, 20 clinically healthy adult goats were divided into two groups of ten animals each: control group (not-treated whole blood donor animals), and experimental group (donor animals which were treated with plasmapheresis). Goats were selected and evaluated through physical examination (vital functions) and complementary tests (complete blood counts, total proteins, albumin, globulin, albumin:globulin ratio, urea nitrogen, creatinine, and plasma free haemoglobin) were carried out at the following moments: immediately before and after blood donation, 12, 24, 72, 120, 240, 360, 480, and 720 hours after the procedures. Results were analysed comparing animals in and between both groups (at differents moments of the study). The clinical observations made during the period of 30 days after donation of 20% of total blood volume, with or without plasmapheresis in the animals of studied groups, were not influenced by these procedures. The results revealed significant variation of eritrogram components, showing the experimental group to have better recovery rates according to time. Based on the results obtained in the present study, plasmapheresis technique application in goats showed to be efficient as a resource to optimize recovery time of blood cell values of plasma donor animals, and did not cause hemolisis during its procedure.
