Dear rekan2,
dulu saya ingat dosen kuliah Elektronika Kedokteran bilang : USG sampai saat
ini BELUM diketahui efek sampingnya.
Saya rasa, jika kehamilan normal, tidak perlu sering2 di-USG. Kalo DSOG-nya
pinter, tanpa USG juga dia bisa melihat perkembangan normal / tidaknya
kandungan. Rata2 dibutuhkan 2-3x USG saja di kehamilan biasa.
Di bawah ini saya kutipkan FAQ dari newsgroup misc.kids ttg. ultrasound :
4. What are the risks of ultrasound?
This question turns out to be controversial. Some of the books which I
consulted reassured that ultrasound has been used for decades with little
risk, and that, while more studies could be done, the studies which have
been done confirm its safety. "Although the effects of ultrasound are
still being studied, no harmful effects to either the mother or the baby
have been found in over 20 years of use. The long-term risks of
ultrasound, if any, are unknown, but there are many benefits." (ACOG :
American College of Obstetricians and Gynecologists)
Others warn that it is insufficiently tested, and make comparisons with
X-rays and DES, which were once considered safe. The main area of debate
is whether ultrasound is being used too frequently in a routine fashion in
healthy pregnancies, without thorough enough testing. There may be some
association between ultrasound and low birth weight (Blatt). (Altho' this
is difficult to prove because the opposite assertion is known to be true:
i.e. if there is IUGR (intra-uterine growth retardation) US will be
performed more regularly to assess the progress of the baby.)
Some people express concern about the heat and cavitation (bubbling in
the cells). Others wonder whether routine ultrasound is cost effective,
or whether the money involved would be more effectively spent elsewhere.
A Consensus Development Conference of the National Institutes of Health
(NIH) was convened to consider the use of ultrasound in pregnancy, and
concluded that "Diagnostic ultrasound is considered to be a low-risk
procedure. However, routine use of ultrasound in pregnancy should be
discouraged." (Blatt) They recommended ultrasound only for twenty-eight
specific instances. (The use of diagnostic ultrasound in pregnancy.
Washington, DC. Government Printing Office, 1984.) In contrast, Germany,
France, and the UK have adopted a policy of ultrasound for all
pregnancies. (NEJM, 1/14/93, Prenatal Diagnosis)
