I dont get US's!!! Or dopplar. Here's some good info I just read on the subject actually on one of my favorite nutrition site's, the weston a price foundation.
" Dangers of Ultrasound: Overheating of the fetus: inhibits enzyme reactions, enzymes may be unable to function, even after temperature returns to normal.
HEATS BONE (SKULL) more rapidly than soft tissue, subjecting brain to continued heat after ultrasound exam.
Recorded sound in uterus “as loud as a subway train coming into the station.”
Frequent exposure associated with decrease in birth weight, increase in left-handedness, delayed speech.
Focused on baby’s genitals to determine sex: Defects of genitals has greatly increased, now affecting one in ten babies
Focused on the heart. Serious defects of the heart increased nearly 250 percent between 1989 and 1996
In 1993, FDA approved 8-fold increase in equipment output.
Since that date, incidence of autism has increased nearly 60-fold.
Highest in U.S., Japan, Scandinavia, Australia, India and U.K., countries where most pregnant women are exposed to ultra-sound."
What to do:
AVOID PRENATAL SCREENING: Ensure a healthy baby with good pre-conceptual and pregnancy diet. Let baby’s sex be a surprise!
INSIST ON A FETOSCOPE during pregnancy, do not allow“Doppler” fetal monitor. Avoid hospital birth if possible.
FOR HIGH RISK MOTHERS (older, many babies, family history, poor nutrition, baby conceived during period of stress), one screening for birth defects may be justified. Should be set at lowest possible level and for shortest period of time."
(as far as autism goes I dont think this is THE cause, I believe that autism has so many contributing factors, but I believe that basically it is a toxic buildup for the most part, and much of it is environmental and over a lifetime (the mother's exposure to toxins over her lifetime and what is in her body while baby is developing and that baby therefor has in his/her body), but ultrasound could possibly be a contributing factor as well.)
