A threatened abortion is a condition of pregnancy, occurring before the 20th week of gestation, that suggests potential of miscarriage. Approximately 20% of pregnant women experience some vaginal bleeding, with or without abdominal cramping, during the first trimester. This is known as a threatened abortion. However, most of these pregnancies go on to term with or without treatment. Spontaneous abortion occurs in less than 30% of the women who experience vaginal bleeding. [1]

周軍;李大劍;李偉莉;陸耘;劉春麗
目的：觀察固腎 安胎飲配合西藥治療早期先兆流產腎虛的療效。方法： 將確診為早期妊娠已出現陰道出血的54例先兆流產患者隨機分為治療組30例和對照組24例，兩組均在監測血清絨毛膜促性腺激素(HCG)和孕酮(P)水平 的情況下，治療組給予固腎安胎飲配合西藥治療，對照組採用單純西藥治療，對比觀察臨床療效。結果：治療組愈顯率為83.3%，對照組愈顯率為54.1%。 兩組比較，差異有顯著性(P<0.05)。HCG、P值低於正常孕期的，治療組10例流產率為10%，對照組9例流產率為55.6%。兩組比較，差異有顯 著性 (P<0.05)。治療後 HCG、P上升與同孕期相符的，治療組明顯高於對照組(P<0.05)。 結論：固腎安胎飲配合西藥治療對於提高早期先 兆流產血清HCG、P水平及臨床愈顯率均優於單純西藥治療。
