Subject: Re: Nuchal Cord Redux
When I review articles and see 100% I get immediately suspicious. I have a
long history of collecting errors and I do not believe in any 100% in
Medicine. I know several of the authors and they are conscientious people. I
would suspect that detection can be very high but I am quite doubtful of any
100%.

I agree 100% with Dr.Fazeel.

> Methods
> A transabdominal ultrasound scan using gray-scale and color
Doppler

nuchal cord.
> The presence of a nuchal cord was classified as present,

> Results
> A nuchal cord was present at 18% of deliveries. The
incidence was not

fluid volume. The
> sensitivity of ultrasound in diagnosing a nuchal cord was
37.5%, with

80%, 29% and

> Conclusions
> The sensitivity of the ultrasound diagnosis of a nuchal
cord is low
> prior to induction of labor at term. A nuchal cord does not
appear to
> increase the risk of Cesarean section or of poor neonatal
outcome. The

use in

pregnancies.
