概括
用低剂量阿司匹林和低分子量肝素治疗死产后的怀孕,在发生胎盘血管疾病的情况下,显著减少了新生儿不良后果. 然而,这些治疗方法的不必要使用增加了母亲的并发症,突出了针对性处方的必要性.
科学领域:
- 产科和妇科 产科和妇科
- 围产儿医学 围产儿医学
- 生殖健康 生殖健康
背景情况:
- 死产是一个毁灭性的怀孕结果,具有显著的情感和身体影响.
- 在死产后的后续怀孕需要谨慎管理以优化结果.
- 药理干预的作用,如低剂量阿司匹林 (LDA) 和低分子量肝素 (LMWH),在改善死产后的结果是正在进行的研究领域.
研究的目的:
- 评估与特定的处方治疗有关的死产后立即怀孕的结果.
- 确定LDA和LMWH单独或组合的疗效,以减少新生儿和母亲的不良结果.
- 根据先前的胎儿死亡和治疗方案的原因来分层结果.
主要方法:
- 这是一项前性观察性研究,涉及2014年至2022年间意大利四所大学医院的308例怀孕.
- 患者有死产史 (怀孕22周以上).
- 根据ReCoDe对先前胎儿死亡原因和治疗方法的分类来分析结果,包括LDA,LMWH,两者,孕激素或其他药物.
主要成果:
- 总的来说,14.94%的后续怀孕对新生儿有不良后果,24.68%对母亲有不良后果.
- 在先前有胎盘血管疾病 (PVD) 的病例中,联合LDA + LMWH治疗将新生儿不良后果降低了75% (OR:0.25;P=0.049).
- 然而,在没有特定适应症的情况下处方的LDA + LMWH显著增加了母亲的不良结果 (OR:3.07;P=0.036).
结论:
- 低剂量阿司匹林和LMWH应保留给有胎盘血管疾病史的孕妇,以改善新生儿的结果.
- 在没有胎盘指示的情况下使用LDA + LMWH与增加母亲并发症风险有关.
- 根据死胎的病因学,针对性地处方LDA + LMWH对于优化孕产妇和新生儿安全至关重要.

Teratogenicity
2.8K
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...

Fetal Circulation
1.4K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Pathophysiology of Diabetes
1.2K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
