To add to this thread, I found this:
"Trendelenberg position - displacement of the abdominal viscera pushes the diaphragm against the heart, which can result in hypotension. You get compression of lung bases by abdominal viscera and you can get increased peak airway pressures. You can see increased ICP in vulnerable patients due to decreased outflow from brain."

As I go through my pile of papers to find how the researchers used trendelenberg, I'll post them. Most of what I have is incidental, mentioned in articles about certain operative procedures. But I got some gems too. This thread has definitely been the best on this topic.
Thanks Gwenth et all,
