Pregnancy

Ectopic pregnancy is the implantation of a fertilized egg outside the uterine endometrial cavity. For women presenting to the emergency department with abdominal pain and/or vaginal bleeding, ectopic pregnancy is an important diagnostic consideration. The diagnosis is made based on laboratory values and ultrasound imaging findings. The ultrasound appearance of both normal early pregnancy and ectopic pregnancy are variable and often subtle, presenting diagnostic challenges for radiologists. This pictorial essay describes and illustrates the sonographic findings of ectopic pregnancy and reviews the differential diagnoses that can mimic ectopic pregnancy on ultrasound...

BACKGROUND: For patients with early intrauterine pregnancy (IUP), the sonographic signs of the gestation may be below the resolution of transabdominal ultrasound (TAU); however, it may be identified by transvaginal ultrasound (TVU). We sought to determine how often TVU performed in the emergency department (ED) reveals a viable IUP after a nondiagnostic ED TAU and the impact of ED TVU on patient length of stay (LOS). METHODS: This was a retrospective cohort study of women presenting to our ED with complications of early pregnancy from January 1, 2007 to February 28, 2009 in a single urban adult ED...

Pelvic pain and vaginal bleeding are common complaints in pregnant women presenting to emergency department. Cervical ectopic pregnancy (EP) is a rare type of EP, with a higher likelihood of complications if missed. Its sonographic findings can be difficult to distinguish from normal pregnancy or an abortion in progress. In this report, we present a rare case of a cervical EP, diagnosed using bedside ultrasonography, and characterize the pitfalls associated with its diagnosis.

OBJECTIVES: Diagnostic ultrasounds by emergency medicine (EM) and pediatric emergency medicine (PEM) physicians have increased because of ultrasonography training during residency and fellowship. The availability of ultrasound in radiology departments is limited or difficult to obtain especially during nighttime hours. Studies have shown that EM physicians can accurately perform goal-directed ultrasound after appropriate training. The goal of this study was to compare the length of stay for patients receiving an ultrasound to confirm intrauterine pregnancies...

BACKGROUND: Evaluation of rates of spontaneous abortion (SAB) may aid in counseling pregnant patients seen in the emergency department (ED). A recent chart review reported an SAB rate of 10% among ED patients with a documented intrauterine pregnancy (IUP) and cardiac activity on ultrasound. We sought to prospectively evaluate outcomes among pregnant ED patients with documented cardiac activity on ultrasound. METHODS: We prospectively enrolled a convenience sample of pregnant patients presenting to the University of Utah ED between January 1, 2008, and April 30, 2009...

STUDY OBJECTIVE: We seek to assess the performance of the β human chorionic gonadotropin (β-hCG) "discriminatory zone" when using bedside pelvic ultrasonography in the evaluation of symptomatic pregnant emergency department (ED) patients. METHODS: This was a cross-sectional study of bedside pelvic ultrasonography performed on consecutive pregnant patients in the first trimester who presented to the ED with abdominal pain or vaginal bleeding. Patients received pelvic ultrasonography, serum β-hCG testing, and blinded formal radiologic ultrasonography...

OBJECTIVE: The purpose of this study was to prospectively assess the learning curve of emergency physician training in emergency bedside sonography (EBS) for first-trimester pregnancy complications. METHODS: This was a prospective study at an urban academic emergency department from August 1999 through July 2006. Patients with first-trimester vaginal bleeding or pain underwent EBS followed by pelvic sonography (PS) by the Department of Radiology. Results of EBS were compared with those of PS using a predesigned standardized data sheet...

STUDY OBJECTIVE: Ectopic pregnancy is a common concern in emergency departments (EDs) and remains the leading cause of first-trimester mortality. Pelvic ultrasonography by emergency physicians has been investigated as a diagnostic test for ectopic pregnancy. We present a meta-analysis of the use of emergency physician ultrasonography in the evaluation of patients at risk of ectopic pregnancy. METHODS: A structured search was performed of both MEDLINE and EMBASE...

OBJECTIVE: Emergency department targeted ultrasonography (EDTU) offers the possibility of rapid exclusion of ectopic pregnancy in patients with first-trimester pelvic pain or bleeding. We sought to systematically review the evidence describing the diagnostic accuracy and clinical utility of EDTU in the first trimester of pregnancy, and to generate a pooled estimate of the sensitivity and specificity of EDTU for the detection of intrauterine pregnancy (IUP). METHODS: The literature search, abstract review and study selection were performed using predefined criteria...

BACKGROUND: Ectopic pregnancies are frequently present in women who present to the emergency department with pregnancy and abdominal pain or bleeding, a subset of whom may require operative intervention. OBJECTIVES: To prospectively determine if emergency physician (EP)-performed transabdominal pelvic ultrasonography (US) with determination of free abdominal fluid in the hepatorenal space predicted the need for operative intervention. METHODS: Patients who were suspected to have an ectopic pregnancy were prospectively enrolled over a ten-month period...

OBJECTIVE: To determine whether patients presenting to the emergency department (ED) with first-trimester pregnancy complications have a decreased length of stay (LOS) when a live intrauterine pregnancy (IUP) is diagnosed by emergency physicians (EPs). METHODS: This study was performed at an urban community ED with a residency program and an annual census of 65,000. A retrospective chart review from October 1995 to August 1998 identified 1,419 patients who received ultrasound examinations confirming live IUP in the first trimester with pain and/or bleeding...
