Talk:2010 Group Project 1

Oops, well I was just following Nany :P

So ultrasounds are done differently at different stages of the pregnancy, in the first, second and third trimester and they can also be used in the delivery process. Therefore I think the use and techniques of ultrasound would be best divided up into those 4 categories;

1. First Trimester

               Ultrasounds preformed vaginally

2. Second Trimester

Ultrasounds preformed on maternal abdomen

3. Third Trimester

Also preformed on mummy’s tummy

4. Delivery

To guide the inducing of a foetus or to determine if a caesarean is necessary

Ultrasound in Labour and Delivery

The routine ultrasound done for most women at 18-20 weeks generally looks for the following things;

• Foetal growth

• Foetal age/Delivery date

• Heartbeat

• Placental positioning

• Identify possible congenital abnormalities

• Detect ectopic pregnancies

• Check for multiple pregnancy

• Determine sex (just out of interest to parents, not medically necessary)

The below articles looks at some of the above characteristics and how they are used; US evaluation of foetal growth: prediction of neonatal outcomes.

First- vs second-trimester ultrasound: the effect on pregnancy dating and perinatal outcomes.

Transvaginal sonographic assessment of cervical length changes during triplet gestation.

Curve of normal fetal weight values estimated by ultrasound according to gestation age

Also used to guide other diagnostic procedures such as chronic villus sampling and amniocentesis.

That’s mostly normal uses at the moment, will look at their use in diagnosis of abnormalities later --z3288088 01:57, 12 August 2010 (UTC)

Hey again guys! (I think we're supposed to post at the top of the page instead of the bottom, so that's what I'm doing, if you're wondering.) So in terms of links to search Pubmed I made these last week on my student page so I'll paste them here. And I also have the Wiki code here for making the reference list and referencing Pubmed articles, for future reference.

Hi group! So we should probably decide how much of the incredible amount of information on ultrasounds we're going to cover. I'm going to suggest - and feel free to disagree/agree/comment/whatever - that we do a least a bit on the sicence of how ultrasounds actually work before going into how you can use them to diagnose conditions prenatally. We're supposed to have at least one student-drawn diagram on our page and I figure we could have a diagram explaining how an ultrasound works, which would cover that objective. If you guys think it's an okay idea, I'd like to offer to cover this point - I love finding out how things work.

Also, if you have the time, could we just quickly email each other (even just a blank email) so we know the addresses work and no-one has a wrong spelling or anything? And whilst you guys have my email, I failed to be organised and don't have yours, so if it's not too much trouble to drop me a line... Thanks! :) --z3252833 01:18, 9 August 2010 (UTC)

hey there ... ermm i totally think the knowing how it works before jumping to prenatal diagnosis would be a great idea...and I am totally cool if you want the hand drawn image to be on how ultrasound works ... but wont that be complicated ? isnt drawing prenatal ultrasound be easier (like a pregnant women and the machine on her stomach) - if that made anysense lol .. and yes i would send u both email immidiatly ... (nany) :) --Navneet Ahuja 09:05, 9 August 2010 (UTC)

The science idea sounds good, and I agree with Sam it would be a good one for a diagram. I also think a historical overview of the development and use of ultrasound might be good. Then what its used for in terms of diagnosis (obviously necessary) and perhaps also a section on the risks, though they are few they do exist and there are reports/studies on them. I think this would be interesting... Anyway I will see you in 20minutes-ish so we can discuss it. --z3288088 22:42, 11 August 2010 (UTC) PS. forgot to email you, will do soon :)
