The use of ultrasound (US) is common in some settings before an abortion procedure. However, its positive effect on the safety or efficacy (ability to complete abortion) of the procedure has not been established. Our aim was to determine whether the use of pre-procedure US improves safety and/or efficacy of the abortion procedure.
We searched the following databases: Pubmed, Embase, Lilacs and Popline; reference lists of retrieved papers; and Google. We considered any controlled trial comparing women seeking abortion who received pre-procedure US to those who did not. Our outcome measures were efficacy of the abortion, complication rates and side effects.
We did not identify any controlled trials or systematic reviews comparing the use of pre-procedure US to no US prior to abortion.
Ultrasound is widely used in pregnancy to estimate gestational age and to detect any abnormalities of the pregnancy or uterus. The effect of its use among women undergoing abortion is unclear, and only indirect evidence is available.
在某些堕胎程序之前，超声（US）的使用很常见。然而，其对手术安全性或效果（完成堕胎的能力）的积极影响尚未得到证实。我们的目的是确定术前 US 的使用是否提高了堕胎程序的安全性和/或效果。
我们搜索了以下数据库：PubMed、Embase、Lilacs 和 Popline；检索到的论文的参考文献列表；和 Google。我们考虑了任何将接受术前 US 的寻求堕胎的妇女与未接受 US 的妇女进行比较的对照试验。我们的结局指标是堕胎的效果、并发症发生率和副作用。
我们没有发现任何对照试验或系统评价比较术前 US 与堕胎前不使用 US。
超声广泛用于妊娠，以估计胎龄，并检测妊娠或子宫的任何异常。其在接受堕胎的妇女中的使用效果尚不清楚，只有间接证据。
