Ultrasound has rapidly become an essential tool in the emergency department, specifically in procedural guidance. Its use has been demonstrated to improve the success rate of procedures, while decreasing complications. In this article, we explore some of these specific procedures involving needle guidance and structure localization with ultrasound.

OBJECTIVES: Traditionally, emergency physicians (EPs) have used anatomic landmark-based needle aspiration to drain peritonsillar abscesses (PTAs). If this failed, an imaging study and/or consultation with another service to perform the drainage is obtained. Recently, some EPs have used ultrasound (US) to guide PTA drainage. This study seeks to determine which initial approach leads to greater successful drainage. The primary objective of this study was to compare the diagnostic accuracy of EPs for detecting PTA or peritonsillar cellulitis (PTC) using either intraoral US or initial needle aspiration after visual inspection (the landmark technique [LM])...

BACKGROUND: We studied the reasons why patients undergoing thoracenteses performed in our outpatient pulmonary clinic had a higher frequency of iatrogenic pneumothorax compared to that in the concurrent radiology practice in our institution, which utilizes ultrasound guidance. We reviewed our practice model and implemented a unique experiential training paradigm in a zero-risk simulation environment to improve efficacy, timeliness, service orientation, and safety. METHODS: We retrospectively determined the rate of clinically significant pneumothoraces in our practice (phase I, July 1, 2001, to June 30, 2002)...

OBJECTIVE: Evidence showing the systematic utility of ultrasound imaging during lumbar puncture (LP) in the emergency department is lacking. Our hypothesis was that ultrasound-assisted LP would increase the success rate and ease of performing LP with a greater benefit in obese patients. METHODS: This was an Institutional Review Board-approved, randomized, prospective, double-blind study conducted at the emergency department of a teaching institution. Patients undergoing LP from January to December 2004 were eligible for enrollment...

OBJECTIVE: This study was conducted to assess the ultrasound's (US's) ability to identify pertinent landmarks for lumbar puncture (LP) in patients of various body mass indices (BMIs) and establish spatial relationships of pertinent LP landmarks across BMIs. METHODS: In this institutional review board-approved cross-sectional study, we calculated the BMIs of eligible patients and then categorized them as normal (BMI < or =24.9), overweight (BMI 24.9-30), or obese (BMI > or =30)...

STUDY OBJECTIVE: To determine if emergency center ultrasound (ECUS) can be of value to emergency physicians in the evaluation of possible ascites and accompanying decisions to perform emergent paracentesis. METHODS: During a 7-month period, patients suspected of having ascites and potentially requiring paracentesis were prospectively entered into a randomized study in an urban public hospital emergency center (>140 000 annual visits). Patients were randomized to receive paracentesis using the traditional or the bedside ECUS-assisted technique...

Lumbar puncture is a common procedure performed in the emergency department for evaluation of several life-threatening conditions, including meningitis and subarachnoid hemorrhage. We describe the use of bedside ultrasound to assist in performance of the lumbar puncture in situations where the standard "blind" technique of needle insertion using palpable spinal landmarks is likely to be difficult or to fail. Use of ultrasound to guide lumbar puncture needle placement was originally reported 30 years ago in the Russian literature...

OBJECTIVES: To evaluate consecutive therapeutic echocardiographically (echo)-guided pericardiocenteses performed at Mayo Clinic, Rochester, Minn, from 1979 to 2000 and to determine whether patient profiles, practice patterns, and outcomes have changed over time. PATIENTS AND METHODS: Consecutive echo-guided pericardiocenteses performed between February 1, 1979, and January 31, 2000, for treatment of clinically significant pericardial effusions were identified in the Mayo Clinic Echocardiographic-guided Pericardiocentesis Registry...
