Autologous Blood Transfusion

Abstract

involved in the action of peptide hormones, startling in its breadth of coverage. Professor Catt came armed with no less than 6 other seminars -a remarkable achievement. The greatest demand was for those on angiotensin and aldosterone, as well as those on the gonadotrophin-releasing hormones. He had detailed laboratory discussions with between 5 and 12 endocrine investigators each day, and all remarked on his perspicacity and helpfulness in discussing their research. Professor Catt proved to be indefatigable, despite what a distinguished British professor described as 'an itinerary for his destruction', and the educational value of his visits to young British researchers proved immense. Perhaps his only moments of peace and quiet were on a train, or when staying at the Domus Medica. He was, of course, entertained by the Clinical Endocrinology Trustees and also by the officers of the Section of Endocrinology.The value of such visits, however, is not just oneway, and is well exemplified by Professor Catt's remark to me that he had not previously realized how well focused is British endocrine research, nor how diverse. British endocrinology and the Section of Endocrinology in particular express their gratitude to Professor Catt and the Trustees for making such a marvellous visit possible.

Determining Safe Limits for Untransfused, Outpatient Liposuction: Personal Experience and Review of the Literature

“…Acute loss of 20% of blood volumes is usually well tolerated in a healthy individual 33 . However, exceeding this limit may require blood replacement, and the necessity for blood transfusion increases the risks of liposuction 33,35,36 . Happily, the use of transfusion is generally rare except in the much less common, large volume liposuction procedures exceeding about 3000 cc fat removal 25…”

“…Administering this blood avoids many of the side effects of homologous transfusion, but autologous transfusion is not without risks. Clerical error or contamination during handling are possible dangers 35 . Also, because of limitations on the survival of banked blood, only 1 or 2 units can be obtained in this manner 37 .…”
