摘要：Objective: To compare d.gital and.ultrasonographic cervical examination for the pred.ction of preterm d.livery in patients hospitalized.for preterm labor. Stud. d.sign: Fiftynine patients were includ.d. The Bishop score was evaluated.upon ad.ission, weeks gestational age. Ultrasonographic measurement of cervical length was d.ne within 24 h after entry. d.livery before 37 weeks gestational age was the primary end.oint. Attend.ng obstetricians were blind.d.to the results of echography. Results: Preterm d.livery rate was 39%(23/59). The risk of preterm d.livery was significantly increased.when the Bishop score was greater than or equal to 6 (OR=4.45 [1.41-14.01]) or when ultrasonographic cervical length was less than or equal to 27 mm (OR=4.04 [1.32-12.3]), but d.gital examination was the only ind.pend.nt risk factor in multivariate analysis. Sensitivity, specificity, positive and.negative pred.ctive value for d.gital examination and.ultrasonography were respectively 74, 61, 55 and.79%, 70, 64, 55 and.77%. Combination of d.gital examination and.ultrasonography d.d.not yield.better results. Conclusion: In our series, pred.ction of preterm d.livery was not improved.by ultrasonography compared.to d.gital examination. The size of the cervical shift observed.in most patients hospitalized.for preterm labor may rend.r ultrasonography less relevant in id.ntifying patients anticipated.to d.liver prematurely.
