Re: Morning sickness & UltrasoundsFrom: Terry (anonymous@obgyn.net)Thu, 11 Sep 1997 16:58:36 -0500 (CDT)

While sonographers do not usually deal with morning sickness, I will
tell you what I know. Morning sickness varies from person to person
(and pregnancy to pregnancy), some have it more or less sever and for
longer periods of time. It should continue to be less as your pregnancy
progresses.
> Now sonography (ultrasound) is something that I do know about. Originally there was only one type of sonographic examination performed, the BEST the sonographer knew how to do. Then at some point in the early 1980's sonographic equipment moved in every corner of medicine. Many people who started using it had no formal training. When they ran into a problem that they did not understand instead of saying "I don't know what I am doing." they would say, "Oh, this is just a small machine that can only do Level 1 sonography. We will have to refer you to someone who can do Level 2." At some point in the mid to late 80's this terminology became generally accepted. Then others started doing what they call Level 3 to show that their exams were better. There is no formal definition of what these various levels are, or of what they are composed. Dr. Roy Filly, Univ. California San Francisco, once wrote an editorial (AJR) titled: "I'll see your Level 2 and Raise you 5". His point was that Levels really should not mean anything, and everyone using sonographic equipment should be properly trained and do the very best job they can on every case. However, because there seems to be no risk from ultrasound to the patient there are no laws limiting who can buy or use sonography. This unlike X-ray, which we know is dangerous, and which use the government controls. There are, unfortunately, wide variations in the skills of those who use sonography. I would suggest that people who have formal training and have set for and passed the American Registry of Diagnostic Medical Sonographers (ARDMS) written examinations perform the best examinations. This is the ONLY certifying body for sonography in the United States or Canada. Anyone not ARDMS certified may or may not know what they are doing. It does not matter if the person has a M.D. degree or not, they still may not know what they are looking at on a sonogram. Sonography is a uniquely difficult procedure that many believe is simple to perform, and a skilled sonographer can make it look misleadingly simple. I hope this answers your question. If not, feel free to contact me. -- Peace, Terry J.
