Study of the Influence of Negative Pressure on Uterine Endometrium of Patients with Early Pregnancy Abortion
Abstract：Objective:To analyze the effect of different negative pressure on uterine endometrium of patients with early pregnancy abortion.Method:168 patients of abortion from January 2011 to April 2013 in our hospital were as the research objects,according to the different negative selection were divided into A, B two groups,84 cases in each group,negative pressure was 500 mm Hg group A,the negative pressure was 400 mm Hg in group B.Complications of patients after operation in two groups were studied.Result:The postoperative bleeding time of two groups,there was not statistically significant(t=1.385,P>0.05).But after 3 months,there was statistically significant about menstruation (χ2=36.723,P<0.05),normal menstruation rate in group B reached 80.95%,was significantly higher than 47.62% in the control group.The endometrial volume and the blood flow abnormal rate in group B was lower than that in group A,there was statistically significant(χ2=6.222,P<0.05).The incidence rate of IUA,there was not statistically significant(χ2=2.385,P>0.05).Conclusion:The maximum negative pressure under 400 mm Hg is conducive to the protection of the endometrium,reduces the postoperative complications.
