概括
金属对金属部植入物释放和离子,这些离子在带血液中显著减少. 带有这些植入物的母亲所产生的大多数婴儿都是健康的,离子水平与胎儿并发症之间没有联系.
科学领域:
- 整形外科手术 整形外科手术
- 生物材料科学 生物材料科学
- 生殖健康 生殖健康
背景情况:
- 在关节整形术 (THA) 和关节表面修复中,金属对金属 (MoM) 轴承表面引起了怀孕患者对金属离子暴露的担忧.
- 金属离子在胎盘中潜在的转移导致了对孕期妇女的MoM植入物的建议.
研究的目的:
- 系统地审查关于MoM轴承类型和离子水平的文献.
- 为了评估母体和带循环中的金属离子度.
- 为了评估MoM部植入物母亲产生的婴儿胎儿异常的发生率.
主要方法:
- 对1975年至2019年间发表的研究进行了全面的文献搜索.
- 纳入标准侧重于使用MoM部植入器的怀孕,母亲/带血金属离子水平,以及胎儿并发症.
- 提取的数据包括离子水平 (,),母亲/婴儿健康,分娩时的年龄,以及从植入到分娩的时间.
主要成果:
- 六项研究分析了21名女性和21名婴儿. 平均母体血液中的: 34.09 微克/升;平均带血中的: 22.61 微克/升 (34%的减少).
- 平均母体血液中的含量:18.18微克/升;平均含量:3.96微克/升 (78%的减少).
- 在21名婴儿中,有20名婴儿健康出生;有一个并发症与植入物无关. 在3名婴儿的带血中没有检测到离子.
结论:
- 来自MoM植入物的金属离子 (,) 与母体循环相比,在带血液中显著减少.
- 目前的证据表明,带血液中的金属离子水平与胎儿不良结果之间没有相关性.
- 关于MoM植入物在孕妇中的使用和潜在的胎儿风险,需要进一步达成共识.

Mitral Valve Prolapse III: Nursing Management
16
The nursing management of Mitral Valve Prolapse, or MVP, centers around patient education, symptom monitoring, and lifestyle modifications.Patient Education on MVP Diagnosis and Heredity: Nurses should provide comprehensive education about MVP, a condition where the mitral valve does not close appropriately during heartbeats. This education often includes the condition's pathophysiology, symptoms, and potential complications, like arrhythmias or mitral regurgitation. Though not fully...

Teratogenicity
2.5K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
