Abstract:

Objective To observe the clinical effects of vacuum-aspiration induced abortion of early-early pregnancy. Methods Clinical data of 5 742 women (the early-early pregnancy group) who underwent vacuum-aspiration induced abortion of early-early pregnancy (amenorrhea ≤ 42 d and the mean diameter of the gestation sac diameters ≤ 10 mm) and 2 935 women (the routine group) who underwent vacuum-aspiration induced abortion (amenorrhea for 43-50 d and the mean diameter of the gestation sac diameters > 10 mm) were collected. The early-early pregnancy group was further divided into two subgroups, i.e. amenorrhea≤36 d group (n=902) and amenorrhea=37-42 d group (n=4 840). The amount of bleeding during induced abortion, amount of aspirated abortus, aspirating time, incidence of complications (induced abortion syndrome and perforation of uterus), and outcomes of induced abortion were analyzed and compared. Results The amount of bleeding and aspirated abortus (P<0.000 1) and the operating time (P<0.01) of the early-early pregnancy group were significantly less than those of the routine group. The incidence of induced abortion syndrome (P<0.05) and perforation of uterus (P<0.001) of the early-early pregnancy group was significantly lower than that of the routine group. The differences of outcomes of induced abortion of two groups were not statistically significant (P>0.05). The amount of bleeding and aspirated abortus (P<0.000 1) and the operating time (P<0.01) of the amenorrhea≤36 d group were less than those of the amenorrhea=37-42 d group. Conclusion Compared to the routine vacuum-aspiration, the advantages of vacuum aspiration of early-early pregnancy are less bleeding, less amount of aspirated abortus, and shorter operating time. For woman with amenorrhea≤36 d, the advantages of vacuum-aspiration induced abortion are more significant.
