Norplant contraceptive implants are silastic implants containing levonorgestrel. This study describes our experience with 100 acceptors of Norplant implants in Singapore. There were no infections at the site after the implants were inserted. No pregnancies occurred during the first year of use. Disruptions of menstrual rhythm was the main complaint. However, the incidence of menstrual irregularities appeared to diminish with time. Implant users have tolerated this early disruption of their menstrual rhythm well and the continuation rate at the end of the year was 96.6 percent. Thus, it appears that Norplant contraceptive implants offer a highly effective means of contraception which should become well accepted in the near future.
Norplant避孕植入剂是含有左炔诺孕酮的硅橡胶植入剂。本研究描述了我们在新加坡对100名接受Norplant植入剂使用者的经验。植入后植入部位无感染情况。使用的第一年无妊娠发生。月经周期紊乱是主要的主诉。然而,月经不规律的发生率似乎随时间而降低。植入剂使用者对这种早期月经周期紊乱耐受性良好,一年末的续用率为96.6%。因此,Norplant避孕植入剂似乎提供了一种高效的避孕方法,在不久的将来应该会被广泛接受。
