The Womb of the Unknown Pregnancy
The Art of Classical Obstetrics
With the
advent of ultrasound and specific urine and blood tests, the diagnosis
of pregnancy is pretty much a no-brainer. But there is a certain
romance of sorts in the history of pregnancy diagnosis before these modern
aids were in common use. Doctors used to be trained differently,
using judgement and diagnostic skills that would today seem obsolete.
Today we can clinically pin-point ovulation and conception, so current
obstetrical books do not dwell on the diagnostic measures that relied on
the signs and symptoms of yesteryear.
Back when the early diagnosis
of pregnancy was an art, there was a certain bonding phenomenon that occured
with the tracking of the conditions described below. Today we're
handed ultrasound pictures of baby on a silver platter before Chadwick
or Goodell (see below) could ever enter the picture, and we're spoon-fed
rising hCG titers almost before the period is late. In earlier non-sophisticated
times, many women couldn't get the diagnosis of their "delicate condition"
until mid-pregnancy.The signs and symptoms described below were
in fact the practice of medicine back then, but now most of them are of
historical significance only.
In spite of the clinical importance,
however, pregnancy is a beautiful mammalian experience; and although the
science of obstetrics has made for better a pregnancy, the beauty of the
art of medicine has been somewhat lost.
Back in the "olden times,"
circa 1960 (last century, remember?), the "old time" diagnotics were grouped
into three classifications:
Presumptive Evidence of Pregnancy--mainly things
perceived by the woman:
-
Cessation of menses--the period stops. Other
things can cause this, but pregnancy and menopause top the list of possiblilies.
-
Changes in the breasts--tenderness early on, then
later the nipples becoming darker and larger. Later on, colostrum
discharge (milk precursor).
-
Chadwick's sign--this is an old term meaning a bluish
discoloration of the vaginal tissue, caused by venous congestion in the
area.
-
Abdominal striae--known as "stretch marks."
-
Increased pigmentation. The "linea nigra,"
or black line, runs up thecenter of the abdomen and usually fades after
pregnancy.
-
Nausea.
-
Increase in urination, due to the pressure of the
growing uterus on the bladder.
-
Fatigue.
-
Quickening--the woman's perception of movement between
16 and 20 weeks. "Quickening" is an elegant and old-fashioned term
associated with the perception of life--a thrill of a Creationist flavor.
Probable Evidence of Pregnancy--as determined by
an examiner:
-
Enlargement of the abdomen, presumably due to increase
in size of the uterus. The uterus can usually be felt through the
abdomen after 12 weeks. This sign is more obvious in the abdomens
that have been stretched out before with a previous pregnancy.
-
Changes in the size, shape, and consistency of the
uterus. "Hegar's Sign" is when the uterus becomes so soft, usually at 6
weeks, that it is felt separately from the firmer cervix. Softening
of the cervix usually occurs at about the same time, called "Goodell's
Sign."
-
Braxton Hicks' Contractions--the irregular and unorganized
contractions of the uterus.
-
Ballottement--a mid-pregnancy sign in which the fetus
can be pushed from the mother's abdomen, and felt to bounce back, tapping
an examining finger in the vagina.
Positive signs of pregnancy:
-
Identification of the fetal heart beat separately
and distinctly from that of the mother--hearing the heart beat can be distinguished
from the mother's by simply taking her pulse while listening to the fetal
heart. An examiner hearing blood swishing through the umbilical cord, (the
"funic" or umbilical cord "souffle") is as meaningful as hearing the actual
fetal heart. On the other hand, blood passing through the dilated
uterine blood vessels, the "uterine souffle," is associated with the maternal
pulse.
-
Perception of fetal movement by the examiner; and
-
Recognition of the fetus by X-ray or ultrasound.
Of course,
modern diagnostic techniques make a lot of the "presumptive" and "probable"
signs and symptoms obsolete, quaint, and of an historical interest only.
Yet I get many questions every day in which a woman cites this symptom
or that and then asks, "Can I be pregnant?" It is for these hopefuls
that I answered the question, "What are the signs of pregnancy?"
Which of three groups a woman can identify with will yield the answer,
"Maybe," "Probably," or "Definitely."
