Ultrasound Equipment
One of the foremost common justifications given today for routine ultrasound machines scanning is to detect intrauterine growth retardation (IUGR). Many clinicians insist that ultrasound is the best method for the identification of this condition. In 1986, a professional review of eighty three scientific articles on ultrasound showed that “for intrauterine growth retardation detection, ultrasound ought to be performed only in a very high-risk population.” In other words, the hands of an experienced midwife or doctor feeling a pregnant girl’s abdomen are as correct because the ultrasound machine for detecting IUGR. The identical conclusion was reached by a study in Sweden comparing repeated measurement of the dimensions of the uterus by a midwife with repeated ultrasonic measurements of the top size of the fetus in 581 pregnancies. The report concludes: “Measurements of uterus size are a heap of effective than ultrasonic measurements for the antenatal diagnosis of intrauterine growth retardation.”
If doctors continue to attempt to detect IUGR with ultrasound machine, the result will be high false-positive rates. Studies show that even below ideal conditions, such as do not exist in most settings, it’s doubtless that over [*fr1] of the time a positive IUGR screening take a glance at using ultrasound is returned, the test is false, and therefore the pregnancy is in fact normal. The implications of this are nice for producing anxiety in the girl and also the probability of further unnecessary interventions.
We are left with the conclusion that, with IUGR, we generally tend to can solely stop a little quantity of it using social interventions (nutrition and substance abuse programs), are terribly inaccurate at diagnosing it, and have no treatment for it. If this will be the present cutting-edge, there’s no justification for clinicians using routine ultrasound during pregnancy for the management of IUGR. Its use should be limited to research on IUGR.
That ultrasound during pregnancy can not be merely assumed to be harmless is urged by sensible scientific work in Norway. By following up on kids at age eight or nine born of mothers who had taken half in 2 controlled trials of routine ultrasound in pregnancy, they were ready to indicate that routine ultrasonography was associated with a symptom of possible neurological problems.
If the machines with all-time low powers are shown to be diagnostically adequate, how can one possibly justify exposing the patient to a dose five,000 times larger? It goes on to urge government guidelines on the output of ultrasound equipment and for legislation making it obligatory for equipment makers to state the output characteristics. As way as is understood, this has not yet been done in any country. Safety is also clearly related to the talent of the ultrasound operator. At gift, there is no known coaching or certification for medical users of ultrasound equipment in any country. In other words, the birth machine has no license take a look at for its drivers.
