Abstract

Early pregnancy loss (EPL) occurs in 15% to 20% of clinically recognized pregnancies. We recommend that patients experiencing EPL have equal access to all treatment options, including expectant, medication, and procedural management, when urgent treatment is not necessary (GRADE 1A). We recommend a patient-centered approach that uses shared decision-making to diagnose EPL through ultrasonography, serial quantitative hCG measurements, or symptoms (GRADE 1C). We suggest a shared decision-making approach for continuing expectant management of EPL up to 8 weeks after diagnosis in the absence of medical complications or symptoms requiring urgent intervention (GRADE 2C). We suggest against Rh testing and Rh-immunoglobulin administration before 12 weeks of gestation for patients undergoing medication management of EPL (GRADE 2B). We recommend a combined regimen of mifepristone with misoprostol for medication management of EPL (GRADE 1A), using mifepristone 200 mg orally followed 7 to 48 hours later by misoprostol 800 mcg vaginally or buccally (GRADE 2A). When used without mifepristone, we recommend misoprostol in two or more doses of 600 to 800 mcg sublingually or vaginally at intervals of at least 3 hours (GRADE 1B). We suggest ibuprofen 800 mg orally for pain control during medication management of EPL (GRADE 2A). Clinicians should offer all patients, but not require, in-person confirmation of completed EPL (GRADE 2B). We recommend against using endometrial thickness alone as a criterion for recommending additional intervention after medication management of EPL (GRADE 1B). We recommend institutions and clinicians make thorough efforts to obtain and maintain access to mifepristone in clinical settings where patients receive EPL care (GRADE 1C).

摘要

早期妊娠丢失(EPL)发生于15%至20%的临床确诊妊娠中。我们建议,对于发生EPL的患者,在无需紧急治疗时,应平等获得所有治疗选择,包括期待治疗、药物治疗和手术治疗(推荐等级1A)。我们建议采用以患者为中心的方法,通过超声检查、连续定量hCG测量或症状,运用共同决策来诊断EPL(推荐等级1C)。我们建议在无医学并发症或无需紧急干预的症状的情况下,采用共同决策的方法,对EPL进行长达诊断后8周的持续期待治疗(推荐等级2C)。对于接受EPL药物治疗的患者,我们建议在妊娠12周前不要进行Rh检测和Rh免疫球蛋白注射(推荐等级2B)。我们推荐米非司酮与米索前列醇联合方案用于EPL的药物治疗(推荐等级1A),即口服米非司酮200mg,7至48小时后经阴道或口腔给予米索前列醇800mcg(推荐等级2A)。若不与米非司酮联合使用,我们推荐米索前列醇分两次或更多次舌下或经阴道给药,每次600至800mcg,间隔至少3小时(推荐等级1B)。我们建议在EPL药物治疗期间口服布洛芬800mg以控制疼痛(推荐等级2A)。临床医生应向所有患者提供,但不要求亲自确认EPL已完成(推荐等级2B)。我们反对仅将子宫内膜厚度作为EPL药物治疗后推荐额外干预措施的标准(推荐等级1B)。我们建议机构和临床医生在患者接受EPL治疗的临床环境中,全力获取并维持米非司酮的供应(推荐等级1C)。
