This article gives a frank assessment of the risks, see paragraph 2 where he says that they place themselves in "exceptional jeopardy" -
" With obstetric hemorrhage being the second-leading cause of maternal mortality in the United States, pregnant Jehovah's Witnesses who refuse all blood transfusion are in exceptional jeopardy, having a 65-fold increased risk of death. 4 It is of paramount importance for clinicians caring for pregnant Jehovah's Witnesses to understand the relevant ethical and legal constructs and to be well versed in the management and alternatives available to this population."
It is a long and technical article which, I hope, will interest those with some medical knowledge but is understandable by anybody..I was particularly interested in the sub heading "Informed Consent" and the third paragraph discussing the wide variety of answers given on the "Health Care Proxies" it seems that nearly 10% would accept Red Blood Cells, which are strictly forbidden. Are they rebelling? Or ignorant of what they really are?
