This study also highlights the niche of point-of-care ultrasound and why it is so critical to our practice as emergency medicine providers. Unlike radiological studies, which require increased time and may be difficult to obtain in critical patients, point-of-care ultrasound allows rapid identification of key findings that allow for early diagnosis and decision making.<\/span><\/p>\n<p style=\"text-align: center;\">Based on this study, the addition of positive fluid seen in Morison's pouch during ED US for suspected ectopic pregnancy now adds on a strong predictor for the need for operative intervention. This is especially important in unstable and hypotensive patients.<\/p>\n<p style=\"text-align: center;\">However, there are several caveats to understand when interpreting this data. First, all the patients in this study were enrolled after having a positive pregnancy test, therefore, prior to assuming that a young female with free fluid in her abdomen is from a ruptured ectopic pregnancy, a pregnancy must first be confirmed.\u00a0 Second, not all free fluid in Morison's pouch in a pregnant woman is due to an ectopic pregnancy. In this data set, there was one patient that had a definitive IUP and free fluid in Morison's pouch which was found to be from a ruptured corpus luteal cyst. There are also case reports of splenic artery aneurysm rupture in pregnancy that could mimic a ruptured ectopic [2]. If an IUP is identified on transabdominal ultrasound, unless the patient is receiving advanced reproductive techniques, alternative explanations for the free fluid should at least be considered before a heterotopic pregnancy is presumed. Third, while this study demonstrates excellent specificity of positive fluid in Morison's pouch and the need for operative intervention in suspected ectopic pregnancy, it has very poor sensitivity. Therefore, ED US should be used as a rule in technique and does not replace formal ultrasound and obstetrical consultation if the diagnosis is not clear.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"mp-row-fluid motopress-row mpce-dsbl-margin-left mpce-dsbl-margin-right\">\n<div class=\"motopress-clmn mp-span12  mpce-prvt-449-595bfa801309a mpce-dsbl-margin-left mpce-dsbl-margin-right\">\n<div class=\"motopress-text-obj\">\n<h2 style=\"text-align: center;\">The Bottom Line<\/h2>\n<h3 style=\"text-align: center;\">Free fluid found in Morison\u2019s pouch in patients with suspected ectopic pregnancy can be rapidly identified at the bedside by emergency providers and predicts the need for operative intervention.<\/h3>\n<p>&nbsp;<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"mp-row-fluid motopress-row mpce-dsbl-margin-left mpce-dsbl-margin-right\">\n<div class=\"motopress-clmn mp-span12  mpce-dsbl-margin-left mpce-dsbl-margin-right\">\n<div class=\"motopress-accordion-obj motopress-accordion motopress-accordion-dark\" data-atts=\"{&quot;active&quot;:&quot;false&quot;,&quot;collapsible&quot;:true,&quot;header&quot;:&quot;&gt; div &gt; h3&quot;,&quot;heightStyle&quot;:&quot;content&quot;}\">\n<div class=\"motopress-accordion-item\"><h3>Authors<\/h3><div>\n<p>This post was written by Michael Macias, MD, Ultrasound Fellow at UCSD.<\/p>\n<\/div><\/div>\n<div class=\"motopress-accordion-item\"><h3>References <\/h3><div>\n<ol>\n<li>\n<ol>\n<li>Rodgerson JD, Heegaard WG, Plummer D, Hicks J, Clinton J, Sterner S.
