The Birth Activist also has an informative post about this device.
Here is information from the manufacturer
And, information about another labor tracking system using ultrasound (not yet approved for use in the U.S.)Thanks to Angie on the MCFI e-list for the three links above!
The comment is made by the manufacturers that the clips on the cervix will not bother the laboring woman because the "cervix has no nerve endings."
My first thought when reading about no nerve endings, was having that sensation during the last weeks of pregnancy that the baby is "biting my cervix" (kind of a sharp *zing* right in the cervix). Or, the "pinched" feeling that I get during pap smears or the aching sensation from cervical bumping of any kind (though perhaps that is actually a uterine sensation and not strictly cervical).
I just googled "nerve endings in the cervix" and the first site to pop up said this, "There are nerve endings in the cervix. They are less dense than other areas but some women have a quite sensitive cervix." Then I read this link from the American Society for Colposcopy and Cervical Pathology: "Sensory, sympathetic, and parasympathetic fibers are present in the cervix. Instrumentation of the endocervical canal (dilatation and / or curettage) may result in a vasovagal reaction with reflex bradycardia in some patients. The endocervix also has a plentiful supply of sensory nerve endings, while the ectocervix is relatively lacking in these. This allows procedures such as small cervical biopsies and cryotherapy to be well tolerated in most patients without the use of anesthesia."
This is different to me than "no nerve endings"!
Makes me think of the days in which baby boys were circumcised without anesthesia because newborns "can't feel pain." I guess women can't feel pain either...
On another note, remember Susan's Hypnobabies interview tomorrow morning on www.HealthyLife.net at 9:00 a.m. Pacific time and Saturday, July 26 at 1:00 p.m. Pacific time.
I'm posting today instead of my usual Friday, because I will be unavailable to post tomorrow.
