为探讨国产Ⅰ、Ⅱ型和Norplant皮下埋植剂对妇女月经血量的影响,对89例健康妇女按随机分配原则,埋植国产Ⅰ型、Ⅱ型和Norplant三种长效避孕皮下埋植剂,测定埋植前及埋植后3,6,12月月经失血量及血红蛋白。埋植前3组平均月经血量(MBL)分别为43.3±6.9ml,48.9±4.3ml,43.7±5.5ml,埋植后MBL在第3周期分别为32.8±13.2ml,24.8±5.5ml,19.7±9.3ml,在第12周期分别为23.9±5.9ml,40.8±10.4ml,25.9±6.0ml,明显低于埋前水平(P<0.05～P<0.001)血红蛋白在埋植后有上升趋势。本研究提示使用长效皮下埋植剂减少妇女月经血量,增加血红蛋白,可以作为妇女选用的高效节育避孕措施。
To investigate the effect of domestic Ⅰ, Ⅱ and Norplant implants on the menstrual blood volume of women, 89 healthy women were randomly divided into three types: long-term contraceptive implants (Ⅰ, Ⅱ and Norplant) The menstrual blood loss and hemoglobin were measured before and after implantation in March, June and December. The mean monthly menstrual blood volume (MBL) in the three groups before implanting were 43.3 ± 6.9ml, 48.9 ± 4.3ml and 43.7 ± 5.5ml, respectively. After the implantation, MBL in the third cycle were 32.8 ± 13.2ml, 24.8 ± 5.5ml and 19.7 ± 9.3ml in the 12th cycle were 23.9 ± 5.9ml, 40.8 ± 10.4ml and 25.9 ± 6.0ml respectively, which were significantly lower than those before burying (P <0.05 ~ P <0.001). This study suggests that the use of long-term subcutaneous implants to reduce menstrual blood, increase hemoglobin, women can choose as an effective contraceptive measures.
