- Abstract
It is known that the cervical length is a predictive factor for pregnancy evolution to term, but there have not been conducted any trials yet to correlate it with myometrial electrical activity on long term. Nowadays, we don't dispose of a simple, widely available technique to objectively monitor uterine contractility during pregnancy, in order to assess the risk of preterm birth. Our aim was to evaluate the relation between clinical elements, the cervical length and the uterine contractility as recorded by antepartum electromyography. In this study were included 113 women with singleton pregnancies, with gestational age 20-29 weeks divided in two groups: 44 women with short cervical length and 69 with cervical length >25mm. The cervical length is indirectly correlated to the mean contraction frequency, and the contraction percentage was significantly lower in the normal cervix group when compared to the short cervix group. The mean number of contractions was slight increase in the short cervix group (11.27±9.59 vs 9.80±7.05 contractions/hour). 58% of the short cervix patients present a significantly high number of contractions/hour, of low amplitude, and more than 55% present great amplitude and duration of contractions. About 67% of the short cervix patients present high contraction areas. Maternal activity between 10 am-11pm was more pronounced for both study groups. Electromiography has proven its efficacy and utility in obstetrical practice for identify a short cervix, which is a risk factor for premature birth, and recommend the proper treatment.
