Personally I wouldn't make a decision based on or one (or even two) research articles. It is important to know if the results have been replicated, are the articles peer reviewed, what is the research design, what are the flaws, are the statistics clear and how have they come up with the conclusion that the monitoring was not helpful.
I would talk to him about the concerns you have now that you have reviewed some of the literature. Good on you for taking control of you and your babies health, but take advantage of the knowledge the OB has as well - some things an article can't and wont cover.
Good luck with it all.
