X-Message-Number: 17717 Date: Sun, 7 Oct 2001 10:41:50 -0400 From: Thomas Donaldson <> Subject: about reviving "dead" brains Hi again! To William Gale and whoever else may wonder about this: it turns out that later work has expanded that time span to almost 10 minutes, with no obvious reason why it cannot be expanded for at least 60 minutes. Even Peter Safar has found methods which allow revival after about 10 minutes. Although the quotation is accurate, it is now out of date. Naturally any aim to increase the time during which some is revivable will involve use of methods not now used. I would suggest that you look up the 1998 tape from 21st Century Medicine (also available from Alcor) of work on cerebral revival. The speaker was Mike Darwin. Work by 21st Century Medicine has done a bit better than Safar as of 1998. Safar himself in P. Safar, NG Bircher CARDIOPULMONARY CEREBRAL RESUSCITATION mentions work with animals which has carried the time of revival out to 15 minutes. Such work clearly won't revive anyone from vitrication or freezing. What it does, however, is point out one obvious way in which our present ideas have changed with current science, and may well change more as our science advances. Best wishes and long long life, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=17717
