Early pregnancy bleeding is a common presentation in the emergency setting. Traditionally, its assessment relied on clinical findings, including pelvic examination. However in recent years, ultrasonography and quantitative beta human chorionic gonadotropin assays have gained prominence and are now first-line in diagnosing early pregnancy bleeding. Accordingly, the role of pelvic examination in the acute setting has been increasingly questioned. This article reviews the evidence for the role of pelvic examination in the assessment of early pregnancy bleeding in the ED. A Medline search was conducted and 43 articles were included in this review. Applicable research is largely observational and of a low level of evidence. However, available data indicate that the role of pelvic examination in the assessment of early pregnancy bleeding is limited, providing that there is prompt access to transvaginal ultrasound examination. Pelvic examination does not provide further diagnostic information over ultrasonography used in conjunction with beta human chorionic gonadotropin assays. The routine use of pelvic examination is not supported by the literature. However, when ultrasonography and beta human chorionic gonadotropin testing are unavailable or the results inconclusive, pelvic examination should be considered. Assessment in these instances must focus on identifying possible life-threatening conditions, such as ectopic pregnancy, as well as determining the safety of discharge pending definitive assessment. Speculum examination is indicated in those presenting with severe bleeding or hypotension as removal of obstructing endocervical products can be a crucial resuscitative measure.
早期妊娠出血是急诊中的常见表现。传统上,其评估依赖于临床发现,包括盆腔检查。然而,近年来,超声检查和定量人绒毛膜促性腺激素β测定已经得到重视,现在是诊断早期妊娠出血的一线方法。因此,盆腔检查在急性情况下的作用受到了越来越多的质疑。本文综述了盆腔检查在评估急诊科早期妊娠出血中的作用的证据。进行了 Medline 检索,共纳入了 43 篇文章。适用的研究主要是观察性的,证据水平较低。然而,现有数据表明,只要能够及时进行经阴道超声检查,盆腔检查在评估早期妊娠出血中的作用是有限的。盆腔检查并不能提供比联合使用超声和β人绒毛膜促性腺激素测定更有诊断价值的信息。文献不支持常规使用盆腔检查。然而,在超声和β人绒毛膜促性腺激素检测不可用或结果不确定时,应考虑进行盆腔检查。在这些情况下,评估必须侧重于确定可能危及生命的情况,如异位妊娠,并确定在明确评估之前出院的安全性。对于出现严重出血或低血压的患者,应进行阴道镜检查,因为清除阻碍的宫颈分泌物可能是至关重要的复苏措施。
