1074 Cervical length nomogram in hispanic patients

Most of the studies have been done on general population and none targeted special populations. The transvaginal ultrasound cervical length (TVUCL) included patients with various ethnicities. There are reports that CL differs by race ethnicity. aim this study was to develop a TVUCL normogram in low risk pregnant Hispanic women. All measurements performed between December 2016 2018 at single tertiary care institution were reviewed. We all who self-identified as Hispanic, ages 18 45 years, had singleton pregnancies, underwent universal 16-24 weeks gestation. excluded twin or higher order uterine anomalies cerclage placement time screening history preterm birth. collected demographic data, gravidity, parity, gestational age screen length. Cervical across gestation analyzed LMS method. A thousand analysis (Table 1). Nomogram is shown Figure 1A. 50th, 10th 5th percentiles TVUCLs 4.01 cm, 3.23 3 respectively 2). Compared those delivered term (>37 weeks), spontaneous birth (sPTB) shorter (mean difference (MD): 0.57cm, 95%CI 0.25-0.89; 1B), but medically indicated delivery did not (MD: -0.06cm, -0.25-0.13; 1C). Among deliveries, only deliveries below 28 significantly cervix 0.99cm, (0.21- 1.77)) compared more than weeks. Receiver operating characteristic curve revealed for clinically relevant positive likelihood ratio, cutoff 3.08cm best predicting sPTB 3). nomogram women shows longer previously reported. If validated other studies, may need be used define short Hispanics.View Large Image ViewerDownload Hi-res image Download (PPT)
