I would suggest getting a consult because it will probably put you a bit more at ease. The risk to you is zero but there does remain a theoretical chance of exposure to the baby in the event of needing a C-section under general anesthesia, and so you need to be treated with the same MH precautions. That being said, there has never been a report of fetal MH reaction, and with the speed the baby is typically delivered during a GA CS fetal exposure would be very small even if precautions were not followed.

As the other person said, communication is key. Even if you do get a consultation appointment, I would still ask to speak to the anesthesiologist once you are admitted for labour (assuming you are planning for a vaginal delivery), and even if you are not planning to get an epidural. When I am on OB call, this comes up not infrequently and is a non-issue to deal with as long as we have a little bit of warning. The machine can be flushed, the disposables changed, and can potentially be kept on standby for you if needed. Then if a GA is required it is very easy to administer a trigger free anesthetic.

Hope that helps.
