RESUMEN
<p><b>OBJECTIVE</b>To probe into the method for effectively increasing complete abortion rate of medicine-induced abortion and observe pathological changes.</p><p><b>METHODS</b>Two hundred cases were randomly divided into an observation group and a control group, 100 cases in each group. The observation group were treated by acupuncture at Hegu (LI 4), Sanyinjiao (SP 6), Neiguan (PC 6) and Kunlun (BL 60), and the control group were not treated by acupuncture. The abortion rate, bleeding condition, adverse reaction and pathological changes were observed in the two groups.</p><p><b>RESULTS</b>The complete abortion rate was 96.0% in the observation group, better than 88.0% in the control group (P < 0.05). There were significant differences between the two groups in bleeding time and pathological changes (P < 0.05).</p><p><b>CONCLUSION</b>Acupuncture can increase complete abortion rate of medicine-induced abortion, with shorter bleeding time and less residual villus.</p>
