Hi - I tweaked a few of the sentences. However, there are quite a few comments here that I cannot address. These are questions directed for you, the writer of the paper, such as the contradictory information. You really have to go through this paper first and fix what is being asked in regards to your own knowledge.<br /><br />I am not familiar with this subject all that much -- except that I had propofol for my colonoscopy!!&nbsp;<br /><br />After you address all the concerns to the best of your ability, run the paper by your professor and ask him if you answered the questions. If you need more grammatical tweaks, then I can do those.<br /><br />I really am not able to tweak the meaning of the content.&nbsp;<br /><br /><br />
