You are quite right, Brutha. The methodology must be tight. Peter Fenwick, however, is no Masaru Emoto - the reason why he managed to get the hsopital to even cooperate in such an experiment is that he has absolutely impeccable academic credentials and professional reputation.
Anyway, a few links I just dug up:
Peter Fenwick: Biography & Resources Lateline - 30/10/2000: Near death research . Australian Broadcasting Corp Dr. Peter Fenwick, M.D.: Science and Spirituality
Thought you might find them interesting.
