I am also an OR nurse nd cureently 27wks pregnant..were def not asking for special tx..we new what we were gettn ourselves into when we signed contracts..with that said..the OR is a very fast paced job with hard work nd long hrs..I have anywhere from my 8hrs to 16hrs..I get put in operations with radiation..n orthopedic surgery nd contaminated surgery..when it comes to the point that my body wont give anymore bcz I need to rest..I have non problem gettn a letter from my obgyn stating that I cant work more than 8hrs..it wont be a permanent situation..just until I go on maternity..nd I see nothing wrong with that!
