RESUMEN
<p><b>OBJECTIVE</b>To investigate the clinical curative effect of Lianhuang Decoction (LHD) in treating fetomaternal ABO blood group incompatibility (FM-ABOI).</p><p><b>METHODS</b>Sixty pregnancy women diagnosed as FM-ABOI were randomly assigned to two groups, Group A treated with LHD and Group B treated with Western medicine. The therapeutic efficacy in the two groups was observed.</p><p><b>RESULTS</b>The antibody titer decreased after treatment in both groups to different extent; the effective rate was 90.0% in Group A and 56.7% in Group B. The bilirubin level in cord blood of Group A was lower than that in Group B significantly (P<0.01). No statistically significant difference was found between the two groups new-bom in terms of 5-minute Apgar score, body weight and hemoglobin content in cord blood (P>0.05).</p><p><b>CONCLUSION</b>LHD has good clinical curative effect in treating FM-ABOI, could decrease the serum antibody titer, and prevent the occurrence of postpartum hemolytic disease in newborns.</p>
