Comparative study on the effects of two different abortion methods on complications of repeated pregnancy during gestation and labor

Abstract

Objective To investigate the effects of the drug abortion or induced abortion on complications of repeated pregnancy during gestation and labor. Methods Complications during labor in 986 women with drug abortion(drug abortion group) and 968 women with induced abortion (induced abortion group)were retrospectively analyzed. Results Threatened abortion of pregnant period rate, naturalness abortion rate and repetitive placenta rate were higher in manual work abortion than that in medicine abortion. The difference was significant (P 0.05). In labor period, the incidences of residue of placenta, placenta adhesion, premature rupture of membranes, postpartum hemorrhage and placenta increta in the induced abortion group were significantly higher than those in the drug abortion group(P<0.01 or P<0.05), while there was no significant difference in the incidences of fetal distress between the two groups. The incidences of threatened abortion, placenta previa, postpartum hemorrhage, placenta adhesion, residue of placenta and placenta increta are all higher in those who have induced abortion two or more times than those who only do once. The difference was also significant (P<0.01 or P<0.05). Conclusions The incidence of complications of repeated pregnancy during gestation and labor after induced abortion is significantly higher than that of drug abortion. Therefore, once the contracepton fails, drug abortion is safer than induced abortion to terminate the pregnancy.
