“…10 In yet another study by Barber et al, the specificity, sensitivity, positive and negative predictive values of cervical length for assessing preterm birth was reported as 98%, 26%, , 63.6%, 93.57% respectively, which was slightly lower than that of our study. 11 In a study by Lim et al transvaginal ultrasound for the measurement of cervical length was reported to be a very effective, safe and acceptable technique in predicting the preterm birth. Cervical length was reported to be inversely related to the risk of preterm birth in asymptomatic women.…”

Background: Preterm birth possess a major health burden to the society due to its long -term morbidity, perinatal mortality and high financial expenditures associated with it. Transvaginal ultrasonographic measurement is an effective and objective way of measuring the cervical length. Cervical length <25 mm is considered as the best cervical parameter with a good predictive accuracy for preterm birth. This study was taken up to study the role of cervical length measurement in predicting preterm labor by Trans vaginal sonography (TVS) and to measure cervical length and follow up cases to study the fetal outcome. Methods: Sagital long-axis view of endocervical canal along the entire length was obtained with high frequency endovaginal probe and the length of cervix from external to the internal os was measured. Atleast three measurements were obtained and the best shortest measurement in millimeters was recorded. Transfundal pressure was applied for 15 seconds and cervical length was obtained again. The cases are followed till delivery and outcome is noted. Results: Out of 134 study group of low risk women, 5.9% women and 50% of the women with short cervical length (<25 mm) had preterm birth. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of our study are 75%, 95.2%, 50%, 98.4%, 94% respectively. Among the 134 newborns, majority of the admissions (14) were due to birth asphyxia followed by meconium aspiration syndrome. Conclusions: TVS is a useful technique in assessing the cervical changes during pregnancy and predicting the preterm birth especially when performed between 16-24 weeks of gestational age could identify all the women having short cervical length along with other changes of cervix.

“…18 A total of 184 deliveries (7.2%) occurred before the 37th week. Before the 37th week, the odds ratios (ORs) of spontaneous delivery for cervical lengths in the 3rd, 5th, and 10th percentiles were, respectively, 25.47 (95% confidence interval [CI], 15.5-41.73); 16.98 (95% CI, 11.51-25.05); and 7.55 (95% CI, 5.44-10.5).…”

“…Perinatal morbidity and mortality are mostly caused by preterm delivery. 1,2 Basically, the exact mechanism behind preterm labor was not yet known clearly. However preterm deliveries may cause decidual hemorrhage, cervical incompetence, Mullerian duct abnormalities, fibroid uterus, cervical inflammation, hormonal changes, and uteroplacental insufficiency.…”

Background: Preterm delivery can be associated with substantial perinatal morbidity and mortality. Nearly in 5 to 13% of pregnancies, happening deliveries are preterm before 37 weeks' gestation. Thus, prediction of preterm labor in parturient can provide a window of opportunity to prevent these complications and to be better prepared to deal with them. Hence the current study has been conducted with an objective to assess the efficiency of cervical length and funneling as assessed by transvaginal ultrasonography in predicting preterm labor.Methods: The current study was a prospective study, conducted in the Department of Obstetrics Emergencies, Dhanalakshmi Srinivasan Medical College and Hospital between November 2015 to April 2017. The study population included 60 women with singleton pregnancy of gestational age between 28 + 0 and 36 + 6 weeks and with painful and regular contractions (>1/10 min for at least 1 hour). Cervical length, funnelling length measured at presentation and after 48 hours were considered as predictor variables. The outcomes of interest were delivery within 1 week, delivery before 37 weeks and delivery before 34 weeks.Results: There was a statistically significant difference in cervical length and funnelling length between term and preterm groups at the time of diagnosis and after 48 hours (P <0.001). The positive predictive value increased from 33.3% to 100% with cervical length ≤ 40 mm to ≤ 20 mm. The negative predictive value decreased from 100% to 79.2% with cervical length ≤40 mm to ≤20 mm. To predict a preterm delivery in threatened preterm delivery patients, the sensitivity of a cervical length of ≤25 mm was 77.7%, specificity was 95.2%, the positive predictive value was 87.5% and negative predictive value is 90.9%.Conclusions: Cervical length and funnelling as assessed by transvaginal ultrasonography are efficient in predicting preterm labor.
