Abstract

     Preterm birth is one of the most important obstetric complications in Thailand that causes deaths and disabilities in newborns. In 2017, preterm rate was 12% in Saraburi province. Risk evaluation of preterm birth by transvaginal ultrasonography to measure cervical length in singleton pregnant women with no history of previous preterm birth is considered a good predictor to provide better assessment to their pregnancy, such as using progesterone. This survey aimed to determine the incidence of short cervix in singleton pregnant women. The retrospective study was conducted in singleton pregnant women at gestational age 16th-24th weeks with regular visits to antenatal care clinic at Saraburi hospital between 1st September 2017-28th February 2018. The results showed that the average cervical length in 275 pregnant women was 34.05 mm. Three pregnant women (1.1%) had cervical length shorter than 25 mm and 272 (98.9%) had cervical length equal or longer than 25 mm. Information of delivery can be collected in 256 pregnant women (93.1%) which 26 pregnant women (10.2%) delivered a child before GA 37th week. Of the 26 women with preterm births, one of them had short cervix while the other 25 women had normal cervical length. The one with short cervical length was significantly younger than ones with normal cervical length. In conclusion, cervical length measurement is essential in antenatal care even in those with low risk of having a preterm labor, especially teenage mother.
