Prep for big US?

MommyTori1 · December 2009

I have mine this afternoon and they didn't give me special instructions (e.g. coming in with a full bladder), but on previous u/s they did tell me to have a full bladder. Any idea on how much water you're supposed to generally drink prior to the u/s? Also, if there's something else I should do in preparation? TIA

they told me 1 bottle of water within an hour before is enough.

As long as you dont empty your bladder within the hour that you go you should be fine. No point in making yourself uber uncomfortable

I didn't need to have a full bladder for mine but they also didn't want a completely empty bladder, The ultrasounds are so good now it doesn't require a full bladder anymore.

MIne gave me a sheet for my BIG U/S. It says drink 16 oz 30 to 40 min before. I am also going to drink a little Mt. Dew or Dr. Pepper to make sure baby is awake...Good Luck...can't wait to see your post this afternoon when you return

I asked and they said there was no need to come with a ful bladder. I came in on 12 ounces of OJ and 12 ounces of water and everything was just fine. If they didn't specifically instruct you to come in with a full bladder I wouldn't worry about it. I was way more comfortable not having one!

My big ultrasound is Thursday and I have to drink 32 oz of water beginning one hour before my appointment within 15 minutes. I seriously don't know how I'm not going to explode. As it is, I pee about once every half hour just drinking normally. I think the further along you are the less necessary it is to have a full bladder, but I believe that changes after 20 weeks or so. I would think at 18 weeks you would still need a full bladder. Maybe you could call your doctor and ask?

My instruction sheet says to have a full bladder but when I called to make the appt., they said that's not necessary.

Several friends have told me to have a little OJ so the baby is moving and you're more likely to be able to see the goods.

Also, don't forget your VHS or DVD so they can record (if that's an option at your center).

GL!

A DVD? what would they record, just everything that the tech looks at during the u/s? I've never heard of this but it sounds interesting. Maybe I'll bring one just in case they do do it.

Mine didn't tell me to come in with a full bladder and they actully had me empty it before the u/s.

Also, don't overdo it on the sugar. If you do they won't be able to get the measurements they need because your LO could be too squirmy.

They told me that once you hit 17w, there is no need to drink any water at all before an u/s. I didn't drink any before mine and they were able to see everything!

Alittle OJ if baby is sleeping and a CD.

My doc puts the pics on CD for us.

I also don't need a full bladder, she usually asks if I want to empty it....plus I have to do the normal pee in a cup at the beginning of the appt anyway.
