I told you the last story to tell you a different one. My father is not a computer scientist but as a mechanical engineer and he liked to build things in his spare time in a home workshop with many tools with which he could custom make hand engineered parts built to fit whatever the project required.
As a professional mechanical engineer he worked on national defense projects for a company who contracted with the U.S. government. He didn’t own the patents on any of his work as a employee; all rights to his inventions and collaborations remained the property of the company. Feeling proud to work in defense of your country is a reward in itself.
One of the projects he worked on in collaboration with two other engineers is still in active production. Underwater detection of submarines is performed with sound-waves, somewhat like whale’s communicating with songs that travel across oceans, or like bat’s sending out clicks and listening for the rebound in echo location. Fascinating and not my area to try to explain in more detail. The Sonar detecting equipment that my father helped invent is still in production for the defense of the nation and I am very proud of him and his work.
Since the initial invention of the sound-wave technology the same “ultrasound” technology was adapted for use to make black and white images of the interior of the body that are formed of soft tissue and can’t be viewed with an X-Ray in the way that hard bone tissue can be viewed. The ultrasound technology can be used to view organs or look for tumors and it is now regularly used to view and make images of a fetus during it’s prenatal development.
The use of ultrasound imaging for viewing babies has become almost standard as an early proof of pregnancy even though it is not necessary as lab tests checking hormonal changes are also performed.
The use of ultrasound imaging during pregnancies has become standard in the United States, however women in China may not receive an ultrasound during their pregnancies.
To skip back to the whale song momentarily — try to visualize the sound-waves of a deep long note or tone that is strong enough to travel across an ocean and now the bat clicking. The deep long note travels across the ocean from one whale to another and is heard as communication. Or the clicks of a dolphin or a bat are sent out in long deep or shorter more rapid notes that bounces off an object and returns to be interpreted as a map or echo location. Now try to visualize the ultrasound technician holding an ultrasound device that sends long deep notes through the abdomen into the watery environment surrounding or making up the body of the baby. Sound travels well through liquid and it would be loud.
Research studies on the effects of ultrasound imaging on the expected fetus took place in China with a group of women who were requesting abortions. Other studies with animal subjects have replicated part of the results which showed that ultrasound could cause fetal cells to move out of place within the developing infant. Ultrasound waves when held in one place for a longer time and at a closer distance were found to cause actual movement of fetal cells out of their normal positions. [The animal-based research study.]
Other risks were also noted in the research performed in China, most significantly when the imaging wand was used for ten minutes instead of three and when it was used in an internal, vaginal position instead of using a larger external sweeping motion across the expanse of the abdomen. [pubmed/11776185 ]
The other risks to the infant included increased heat especially within the bony cavity of the skull which has been studied elsewhere without any babies. A container of water was found to consistently have an increase in temperature occur after just one minute of ultrasound exposure. Specific types of ultrasound devices vary somewhat and the recommendations and cautions regarding ultrasound use in pregnancy are available in this research article: [PMC4547707 ] Avoiding use of ultrasounds during the first trimester is recommended in the article and using the lowest settings possible for patients who have a medical need for ultrasound imaging is recommended for prenatal patients in later stages of pregnancy.
Gastroschisis is a rare medical condition in a developing fetus that might require an ultrasound for diagnosis around 18-20 weeks/gestation as surgery would be needed shortly after the baby’s birth as the condition would likely be deadly otherwise. An opening in the infant’s abdomen near the umbilical cord allows some of the intestine and/or liver to be outside of the body. [cincinnatichildrens.org/gastroschisis]
Protecting the developing brain of the fetus is important throughout the pregnancy but the greatest risk to the fetus from ultrasounds may occur during the first trimester according to a research study that took place elsewhere than China.
- A book, by Jim West, a non-Chinese scientist, is available in which the findings from the Chinese studies are summarized for English readers and a Japanese translation is now also available. The book is mentioned on the following site along with a variety of links to research on the topic of the use of ultrasounds prenatally and a potential increased risk for autism developing in the infant later in life: ultrasound-autism.org
- A lengthy review of the book and the history of how it came to be written by Jim West is available here: whale.to/50 Human Studies.
- An excerpt summarizes the recommendation regarding ultrasound use prenatally based on findings by a project that ultimately involved approximately 100 scientists in China and 2,700 maternal-fetal pairs, between 1988-2011 :
“From these human studies, Professor Ruo Feng, of the Acoustic Institute at Nanjing University, published guidelines in 2000:
“Commercial or educational fetal ultrasound imaging should be strictly eliminated. Ultrasound for the identification of fetal sex and fetal entertainment imaging should be strictly eliminated. For the best early pregnancy, avoid ultrasound.”
Ruo Feng, who reviewed many of the studies, stipulated that routine ultrasound be avoided. Only if there were exceptional medical indications should ultrasound be allowed, and at minimum intensity. Sessions should be very brief, no more than 3 minutes, 5 minutes at most. Multiple sessions should be avoided because hazards are cumulative. Human studies had found sensitive organs damaged at 1 minute exposure.
The Chinese studies echo and confirm the earlier, ignored and rejected, 1984 “Consensus Statement”, published by the National Institute of Health and signed by the preeminent American scientists of that era. 2″ – whale.to/50 Human Studies
- I learned of this research on the potential risks of ultrasound when researching other topics on possible causes of autism. Many factors may be involved in the risk of autism developing, which, in combination, can lead to changes occurring in the developing fetus that aren’t obvious in the infant but which may flair up into an autoimmune-like reaction during toddler-hood if there are enough negative factors and not enough or an adequate variety of nutrients and other positive factors in the child’s home life. Genetic susceptibilities are also involved but none identified thus far have been found to lead to autism without there being additional environmental toxins or nutrient deficiencies involved.
- Autism can be caused by the use of thalidomide prenatally. That wouldn’t be recommended as the medication can also cause physical birth defects when used during a pregnancy, however it is a medication used for some non-pregnancy related conditions and there might be an occasional unplanned pregnancy. The point is not only that planning pregnancies is recommended so that prenatal vitamins can be started months in advance (ideally a year prior to conception for least risk of autism in one study); and so that potentially toxic medications can be gradually stopped before trying to conceive; but that if autism can be caused by a medication then how could it also be a natural variation?
- Family studies suggest that personality traits slightly similar to autistic characteristics can be more common in the family members of patients with autism. Protecting the developing fetus from ultrasounds that are too intense, or go on for too long a time causing over-heating can be a simple way to help protect the child’s true genetic potential. Higher functioning people with Asperger’s like symptoms and skills may represent the more natural variation end of the autism spectrum while patients at the least functioning end of the spectrum have likely been exposed to more variety of toxins and possibly with less nutrients available or less genetic detoxification ability available to excrete the toxins.
- The use of ultrasounds in addition to other factors may all be adding up to increased rate of autism that has been seen in our modern culture.
- Using equipment that was originally designed to detect submarines to take pictures of a developing infant is a practice to use cautiously rather than allowing it to become typical for all pregnancies or to be available for non-medical reasons, possibly performed by non-medical staff who may not follow safe procedures in the pursuit of a better image. In some areas the technology has been used for photo-booth type purposes, “Have you noticed ultrasound boutiques popping up in strip malls?”. Read more: birthrelaxationkit.com/ Ultrasound Concerns for Baby’s Development.
- If the damage can accumulate with repeated exposure as suggested by the statement by Dr. Ruo Feng then each additional ultrasound may be adding to the risk of a neurological conditions such as autism.
Ultrasound technology is currently being used medically in other ways then prenatal or soft tissue imaging. It may be used specifically as a heat treatment on sore or cramped muscles during a physical therapy session. And still in the research phases, high frequency ultrasound waves are being used at more intense strengths to actually kill cancer cells. That would be a safer technique for the health of the surrounding tissue than using radiation on cancerous tumors. X-ray type radiation is directed at the tumor in a rotating manner so that surrounding tissue gets less rays while the tumor gets a maximum dose in order to kill the cancerous cells.
So killing cancer cells with high frequency soundwaves sounds like a great idea compared to being rotated on a table while an X-ray is directed at a tumor. Eating healthy and not getting a tumor also sounds good.
- Having an ultrasound during the first trimester of a pregnancy doesn’t sound good to me. Disclosure – I declined any ultrasounds for both of my pregnancies. I had listened to my dad play whale songs for too many hours of my youth to want my babies to have a sound wave ray gun directed at them. My thought at the time, which research suggests was an accurate concern, was, “I don’t want to risk scrambling my baby’s brain just to see what sex it is. I’d prefer to wait and see anyway.”
- At the time of my pregnancies, ultrasounds were still a fairly “new-fangled” invention or service which was offered as a choice rather than being expected with every single “I’m expecting a baby” announcement. Send a photo of the urine test stick instead or the results from the official lab test. Once you’ve seen one black and white fuzzy image of a blob, you’ve seen them all – you can trust me on that. Ultrasound images have become so standard they are used as proof of pregnancy for agencies that offer free services to women who are pregnant and I admired a lot of little adorable blobs — women can be very protective of their babies, no matter what they look like.
So protecting your newly conceived baby’s brain seems worth considering , not just the fuzzy image for a birth announcement.
In high risk pregnancies there may be an increased number of ultrasounds recommended, possibly just to be cautious. It is okay as a patient to ask questions about medical necessity and what is truly necessary and what is possibly being recommended to look thorough in case of a potential malpractice suit. If the ultrasound tests themselves may be increasing risk to the infant though, then how cautious is it to use them more often just because a woman’s pregnancy has some high risk factor?
It’s okay to ask questions. It’s your baby, your body, and your baby’s brain and future at risk.
