本文对放置形状和材料各异的五种宫内节育器的受试妇女,进行了放置前、后(1年之内)月经血量的比较研究。所得结果按IUD材料不同而分成三类:第一类为带铜IUD(V_(Cu200)型10例,T_(Cu220)型10例),放置后引起月经血量显著增加(P<0.05);第二类为不锈钢IUD(环型10例,宫型10例),放置后月经血量虽有增加,但不明显(P>0.05);第三类为释放18甲基决诺酮的含药型IUD(Levonogestrel IUD 13例),月经血量放置后较放置前呈大幅度的下降(P<0.01)。
In this paper, the placement of the shape and material of five different types of IUD women were placed before and after (within 1 year) comparative study of menstrual flow. The results were divided into three groups according to the IUD materials: the first one was copper IUD with 10 cases of V_ (Cu200) type and 10 cases of T_ (Cu220) type). After being placed, the menstrual blood volume was significantly increased (P <0.05); The second type is stainless steel IUD (ring 10 cases, 10 cases of uterine type), although the monthly menstrual blood volume increased, but not significantly (P> 0.05); the third category for the release of 18 methyl metolnone drug Type IUD (Levonogestrel IUD 13 cases), menstrual blood volume after placement was significantly decreased (P <0.01).
