Non-invasive uterine electromyography (EMG) identifies true premature births more accurately than clinical methods currently in use, the results of a new study.

"This method will help to identify those patients who actually showed the early administration of tocolytic therapy, transportation to the hospital with the possibility of intensive neonatal therapy, and the appointment of steroids," says Dr. Robert E.. Garfield (Robert E. Garfield) (St. Joseph's Hospital and Medical Center in Phoenix) and colleagues in his report, which appeared in the online edition of the American Journal of Obstetrics & Gynecology on December 9th.

Together with Reproductive Research Technologies, Dr. Garfield and his colleagues created a device that records EMG; And are now awaiting approval from the US Food and Drug Administration.

At present, midwives rely on the current meters that use tensiometric sensors to estimate the acronyms. Dr. Garfield believes that the new device will someday "replace the equipment that is currently used in the clinic".

Many women hospitalized for premature birth give birth on time.

At the same time, 20% of patients with symptoms who do not diagnose truly premature births give birth early. "This leads to unnecessary treatment, missed opportunities to improve the neonatal outcome, and a significant impact on research methods of treatment," - write the authors.

Given the changes in electrical activity within the myometrium that occur during true births, scientists believed that a mother EMG could help determine whether the patient is in true births or not, give birth prematurely (that is, before 34 weeks).

In studying this issue, the researchers performed EMG 116 in 24 hours after admission, including 20 in premature delivery, 68 in preterm labor, 22 in labor in time, and 6 in non-term delivery.

Twenty women in preterm labor gave birth to their babies for seven days; The results of their examination showed an average speed of 53 cm / s, compared with 11 cm / s in women who gave birth after seven days. The frequency peak in the power spectrum was 0.56 Hz for women in true premature birth, versus 0.44 Hz for women who did not give birth prematurely. No other weighted parameters were different between premature births and nulliparous groups.
