Can Head Position Improve Surgical Field During Ear Surgery?
RandomizedParallel-groupTriple-blindSupportive care
Summary
Middle ear surgeries utilizes microscope in a narrow field. They are better performed under controlled hypotension, to minimize bleeding and improve surgical field visualization and hence improve results.Head-up or anti-trendelenburg position influences intraoperative bleeding by generating regional ischaemia in sites elevated above the level of the heart. Also by augmenting the effect of vasodilators through pooling of blood in dilated veins.
