试管婴儿流产预防指南：科学守护珍贵妊娠 试管婴儿技术的成功，让许多家庭迎来了期盼已久的小生命。然而，妊娠早期（尤其是前12周）的流产风险仍然存在。据统计，试管妊娠的早期流产率约为15%-25%，略高于自然妊娠（10%-15%）。但通过科学的预防和管理，可以显著降低风险，提高妊娠成功率。
一、试管流产的常见原因1. 胚胎因素（占比约50%）2. 母体因素（占比约30%）子宫环境异常：如子宫内膜薄、宫腔粘连、子宫肌瘤等。 免疫因素：如抗磷脂抗体综合征（APS）、NK细胞活性过高等。 内分泌问题：黄体功能不足、甲状腺功能异常（甲减/甲亢）、高泌乳素血症等。 血栓倾向：凝血功能异常（如蛋白S/C缺乏、抗凝血酶III缺乏）。
3. 其他因素
二、科学预防流产的关键措施1. 胚胎筛选：从源头降低风险2. 子宫准备：打造最佳着床环境宫腔镜检查：排除息肉、粘连、子宫畸形等问题。 子宫内膜调理：
3. 免疫与凝血管理抗磷脂抗体综合征（APS）：低分子肝素+阿司匹林治疗。 NK细胞活性高：必要时使用免疫球蛋白（IVIG）或脂肪乳治疗。 凝血异常：根据血栓风险评估，使用抗凝药物（如肝素）。
4. 黄体支持：维持妊娠稳定试管妊娠黄体功能不足风险高，需持续补充：
黄体酮针剂/阴道凝胶 口服地屈孕酮 HCG辅助支持（视情况使用）
5. 生活方式调整
三、试管妊娠后的监测重点1. 早期妊娠监测（0-12周）HCG翻倍检测：48小时应增长66%以上。 孕酮水平：维持在25ng/ml以上较安全。 B超检查：
2. 中晚期管理（12周后）
四、专家建议：如何最大化妊娠成功率？选择有PGT资质的生殖中心，确保胚胎质量。 移植前全面检查：包括免疫、凝血、内分泌等。 个性化保胎方案：根据流产史和检查结果定制用药。 保持良好心态：过度焦虑反而不利胚胎着床。
记住： 试管妊娠来之不易，科学管理能大幅降低流产风险。如出现腹痛、出血等症状，务必及时就医！

划译 The success of in vitro fertilization technology has brought long-awaited little lives to many families. However, the risk of miscarriage in early pregnancy (especially in the first 12 weeks) still exists. According to statistics, the early miscarriage rate of in vitro fertilization is about 15% -25%, slightly higher than that of natural pregnancy (10% -15%). But through scientific prevention and management, risks can be significantly reduced and pregnancy success rates can be improved. 1、 Common causes of in vitro abortion 1. Embryonic factors (accounting for about 50%) Chromosomal abnormalities: The rate of chromosomal abnormalities in eggs of elderly women (≥ 35 years old) significantly increases, which is the main cause of early miscarriage. Insufficient embryonic development potential: Some embryos may experience developmental delay or arrest during in vitro culture. 2. Maternal factors (accounting for approximately 30%) Abnormal uterine environment: such as thin endometrium, intrauterine adhesions, uterine fibroids, etc. Immune factors: such as antiphospholipid antibody syndrome (APS), excessive NK cell activity, etc. Endocrine problems: luteal insufficiency, thyroid dysfunction (hypothyroidism/hyperthyroidism), hyperprolactinemia, etc. Thrombotic tendency: Abnormal coagulation function (such as protein S/C deficiency, antithrombin III deficiency). 3. Other factors Infection: such as TORCH infection (Toxoplasma gondii, rubella virus, etc.), chronic endometritis. External factors: excessive fatigue, high mental stress, unhealthy lifestyle habits (smoking, drinking alcohol). 2、 Key measures for scientific prevention of miscarriage 1. Embryo screening: reducing risks from the source Third generation test tube (PGT-A/PGT-SR): can screen for chromosomal abnormalities in embryos and reduce miscarriage rates by more than 50%. Embryo culture optimization: Using a time difference incubator (EmbryoScope) for dynamic monitoring, select high-quality embryos for transplantation. 2. Uterine preparation: creating the best implantation environment Hysteroscopy examination: ruling out polyps, adhesions, uterine malformations, and other issues. Endometrial regulation: For those with thin endometrium (<7mm), estrogen, growth hormone, stem cell therapy, etc. can be used. Chronic endometritis: requires antibiotic treatment (such as doxycycline). 3. Immune and coagulation management Antiphospholipid Antibody Syndrome (APS): Treatment with Low Molecular Weight Heparin and Aspirin. High NK cell activity: Immunoglobulin (IVIG) or fat emulsion therapy may be necessary. Coagulation abnormalities: Use anticoagulant drugs (such as heparin) based on thrombus risk assessment. 4. Luteal support: maintaining pregnancy stability The risk of luteal insufficiency in IVF is high, and continuous supplementation is needed: Progesterone injection/vaginal gel Oral administration of levonorgestrel HCG assisted support (used as appropriate) 5. Lifestyle adjustments Avoid strenuous exercise: Reduce bending and lifting heavy objects within 2 weeks after transplantation. Balanced nutrition: supplement folic acid, vitamin D, Omega-3, and control blood sugar. Psychological regulation: Anxiety and stress can increase the risk of miscarriage, and mindfulness meditation or psychological counseling can be performed. 3、 Key monitoring points after in vitro pregnancy 1. Early pregnancy monitoring (0-12 weeks) HCG doubling test: It should increase by more than 66% within 48 hours. Progesterone levels: Maintaining above 25ng/ml is safer. B-ultrasound examination: 5-6 weeks of pregnancy: confirm intrauterine pregnancy 7-8 weeks of pregnancy: observe fetal heart rate and fetal buds 2. Mid to late stage management (after 12 weeks) NT examination (11-13 weeks): Screening for chromosomal abnormalities. Non invasive DNA/sheep penetration (16-22 weeks): further exclusion of genetic issues. Cervical function assessment: Twins or those with short cervix require prophylactic cerclage. 4、 Expert advice: How to maximize the success rate of pregnancy? Choose a reproductive center with PGT qualifications to ensure embryo quality. Comprehensive examination before transplantation: including immunity, coagulation, endocrine, etc. Personalized prenatal care plan: customized medication based on abortion history and examination results. Maintain a positive mindset: Excessive anxiety can actually hinder embryo implantation. Remember: IVF is not easy to come by, scientific management can significantly reduce the risk of miscarriage. If symptoms such as abdominal pain and bleeding occur, it is essential to seek medical attention promptly!
