Objective: To analyze the impact of early pregnancy subchorionic hematoma on the pregnancy outcome. Methods: We collected 1 055 cases of pregnant women from January 2014 to December 2015 in the Beijing Maternity Hospital Affiliated the Capital Medical University who had prenatal care and hospitalization production, screening out 23 cases of miscarriage 10 weeks ago. Grouped as follows: group Ⅰ without SCH and vaginal bleeding after 10-week pregnant; group Ⅱ without SCH but with bleeding; group Ⅲ with SCH, no bleeding; group Ⅳ has both SCH and bleeding. Data were analyzed with SPSS13.0 statistical manner. Results: Among 1 032 cases, SCH accounted for 172 cases (16.67%); group Ⅰ, 618 cases; group Ⅱ, 242 cases; group Ⅲ, 87 cases; group Ⅳ, 85 cases. The proportion of flow, preterm birth is respectively group Ⅰ 15.70%, group Ⅱ 30.17%, group Ⅲ 18.39%, group Ⅳ 28.24%. Compare with group Ⅳ, group Ⅰ and Ⅲ have significant differences (P<0.05), but no statistically significant differences between group Ⅱ(P>0.05). About flow and premature birth, there was significant difference (P<0.05) between bleeding (Ⅱ+Ⅳ) and non-bleeding group (Ⅰ+Ⅲ); group SCH (Ⅲ+Ⅳ) and group non-SCH (Ⅰ+Ⅱ) showed no significant difference (P>0.05). Conclusion: Early pregnancy SCH has little relationship with flow and premature birth, but when vaginal bleeding occurs in pregnant women, it will increase the rate of flow and premature birth.
