| Abstract: |
| ［Abstract］ Objective To explore the value of the evaluation of cervical ripeness and the prediction of premature delivery by B ultrasound measurements of cervical length and width of cervical internal opening. Methods The B ultrasonographic examination of 187 hospitalized primipara with singleton fetus were performed to measure the length of uterine cervix and width of cervical internal opening after filling of bladder. Results The length of uterine cervix were <30 mm, width of cervical internal were ≥5 mm, the risk of premature delivery increased.Conclusion The ultrasonogyaphic exam is an objective, effective, and repeatable method in predicting premature delivery. |
