Objective: To investigate the influence of abnormal cervical pap smear undertaken in pregnancy to the outcome of the pregnancy.
Methods: A total of 1 069 primipara deliveried in Beijing Chaoyang hospital from Jan 1999 to May 2001 were reviewed, furthermore we compared the group of normal pap smear (group A) with the group of abnormal pap smear (group B), and analysed the difference of the complications during pregnancy, methods of delivery, the first stage of labor, fetal distress and the outcome of the cervical pap smear postpartum.
Results: The incidence of premature rupture of the membranes and fetal distress in group B, which were 39.39% and 30.30%, respectively, were significantly higher than that of group A, which were 5.21% and 15.25%, respectively (P < 0.01). There was no statistical difference in premature delivery, the ratio of cesarean section and the first stage of labor which were 3.38% and 3.03%, 44.11% and 30.30%, 7.3 h and 7.7 h, respectively (P > 0.05). The regression rate for patients with abnormal cervical pap smear postpartum was 62%.
Conclusions: The outcomes of the pregnancy such as premature rupture of the membranes and fetal distress were affected by the abnormal cervical pap smear undertaken during pregnancy. It is important to undergo routine cervical pap smear examination during pregnancy.
