Abstract
Introduction and Aims of the Study : The frequency of induction of labour (IOL) is rising in obstetrical practice. Specialists search for objective and reliable methods to predict success of IOL.
Aim : to evaluate role of cervical strain elastography in prediction of IOL success.
Methods : The study enrolled 50 patients in Riga Maternity hospital from June’22-January’23. The inclusion criteria: healthy primiparas with singleton pregnancy, cephalic presentation, intact membranes and Bishop score ≤ 6. IOL Method - Foley catheter combined with oral misoprostol.
Cervical tissue strain elastogram was performed on GE Versana Premier ultrasound machine, with transvaginal E8CS probe. The cervical elasticity index (EI) was evaluated based on color map in 3 regions – internal os, cervical canal, and external os. Cervical tissue was rated according to color map: red (soft), yellow (medium soft), green (medium hard), and blue (hard).
Descriptive statistical analysis was carried out using IBM SPSS 24.0 software. Significance level for ANOVA and chi-square tests, denoted by the alpha of 0.05.
Results : The median age of patients was 28 (IQR 6) years, median gestational week 41+1 (IQR 1), median BMI 21.1 (IQR 4.2). Vaginal delivery (VD) was achieved in 90% (n=45): spontaneous VD - 64% (n=32), operative VD - 26% (n=13). Cesarean section - 10% (n=5) of cases. Active labour within 12 hours - 90% (n=45) of cases, and VD within 24 hours - a 86.6% (n=39). No statistically significant association was found between EI cervical regions and mode of delivery. The drawbacks of the study might be small sample size.
Conclusion : Elastography is a novel method to use in prediction of IOL success, and continuous research in larger population is needed.
