Transvaginal Sonographic Measurement of Cervical Length during Midtrimester in Predicting Preterm Labor in Asymptomatic Singleton Pregnancies
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2018, Vol 6, Issue 5
Abstract
Introduction: Preterm delivery is a significant obstetric problem worldwide due to various complications in the newborn in its neonatal period and throughout lifetime. Cervical length is considered as a definitive predictor of preterm labor. Transvaginal sonography (TVS) can detect cervical length shortening earlier and more accurately than digital assessment. Based on this idea, this study is being undertaken to assess the bearing of cervical length measured by TVS at 18–24 weeks gestation on the outcome of pregnancy. Aims: The aims are as follows: (1) To establish the relationship between cervical length at mid-trimester in uncomplicated singleton pregnancies and time of delivery, (2) To assess the potential value of routine cervical length measurement in singleton pregnancy between 18 and 24 weeks in the prediction of risk for early spontaneous preterm delivery Materials and Methods: Study design: This was a prospective case–control study, (1) Study period: The study period was from July 2016 to December 2017 (18 months), (2) Place of study: The study was conducted at the Department of Obstetrics and Gynecology, GTMCH, (3) Study population: All booked cases between 18 and 24 weeks of gestation attending GTMCH who are willing to participate in the study, (4) Sample size: The sample size was 200. Inclusion criteria: All singleton pregnancies who have correct dates (reliable LMP in the background of the regular menstrual cycle [or] ultrasonography dating in the 1st trimester), between 18 and 24 weeks of gestation. Exclusion criteria: Not willing to participate in the study, multiple gestation, polyhydramnios, iatrogenic termination of pregnancy, and patients who missed follow-up. Results: Out of 200 antenatal women upon whom the study was conducted,majority were multigravida which accounts to 79.59%. Out of 200 patients studied, 41 cases had short cervix which constitutes 20.5% of the population and Out of 41 patients with cervical length less than 25mm, around 25 patients delivered preterm. There were 28 NICU admissions out of 43 preterm deliveries. There were 28 NICU admissions of 43 preterm deliveries. Conclusion: Preterm delivery and its effect on perinatal and neonatal morbidity and mortality is a global issue which needs significant attention among health-care personnel. Transvaginal sonographic determination of cervical length in women with asymptomatic singleton pregnancy is both cost-effective and has good validity as an effective screening test.
