Although bleeding problems represent the commonest side effect of IUDs and an important medical reason for discontinuation of use, its pathogenesis still remains incompletely understood and a standard universally acceptable therapy is not yet available. Proper insertion, change in size, material or shape of the IUD, as well as custom fitting to avoid dimensional incompatibilities, did not significantly improve the IUD-associated bleeding problems. Addition of copper to inert devices seemed to slightly improve the bleeding by reducing the antifibrinolytic activity but probably more was achieved through reducing the device size. Hormone-releasing devices appear to reduce the amount of bleeding significantly but a post-insertion phase of irregular spotting is a common complaint. Locally released antifibrinolytic agents were tried in limited investigations but a short period of drug release restricted further evaluation. Systemic administration of antifibrinolytic agents and non-steroidal anti-inflammatory drugs hold promise for the control of IUD-induced menorrhagia. The duration of bleeding and intermenstrual spotting still remains an unresolved clinical problem that requires further evaluation. This area of clinical concern in IUD use needs more in depth understanding and testing of new agents, particularly in the area of local release of antihemorrhagic agents.
尽管出血问题是宫内节育器(IUD)最常见的副作用,也是停用IUD的一个重要医学原因,但其发病机制仍未完全明确,且尚无普遍接受的标准治疗方法。正确放置、改变IUD的尺寸、材料或形状,以及定制适配以避免尺寸不兼容,均未显著改善与IUD相关的出血问题。在惰性节育器中添加铜似乎通过降低抗纤维蛋白溶解活性而略微改善了出血情况,但可能更多的是通过减小节育器尺寸实现的。释放激素的节育器似乎能显著减少出血量,但置入后出现不规则点滴出血是常见的问题。在有限的研究中尝试了局部释放抗纤维蛋白溶解剂,但药物释放时间较短限制了进一步评估。全身使用抗纤维蛋白溶解剂和非甾体抗炎药有望控制IUD引起的月经过多。出血持续时间和经间期点滴出血仍是一个尚未解决的临床问题,需要进一步评估。IUD使用中这一临床关注领域需要对新药物有更深入的了解和测试,特别是在局部释放抗出血药物方面。
