Deep Needle Procedures: Improving Safety With Ultrasound Visualization.

Promoting patient safety and increasing health care quality have dominated the health care landscape during the last 15 years. Health care regulators and payers are now tying patient safety outcomes and best practices to hospital reimbursement. Many health care leaders are searching for new technologies that not only make health care for patients safer but also reduce overall health care costs. New advances in ultrasonography have made this technology available to health care providers at the patient's bedside. Point-of-care ultrasound assistance now aids providers with real-time diagnosis and with visualization for procedural guidance. This is especially true for common deep needle procedures such as central venous catheter insertion, thoracentesis, and paracentesis.There is now mounting evidence that clinician-performed point-of-care ultrasound improves patient safety, enhances health care quality, and reduces health care cost for deep needle procedures. Furthermore, the miniaturization, ease of use, and the evolving affordability of ultrasound have now made this technology widely available. The adoption of point-of-care ultrasonography has reached a tipping point and should be seriously considered the safety standard for all hospital-based deep needle procedures.

The diagnosis of right heart thrombus by focused cardiac ultrasound in a critically ill patient in compensated shock.

Right heart thrombus (RHT) is a life-threatening diagnosis that is rarely made in the emergency department (ED), but with the increasing use of focused cardiac ultrasound (FocUS), more of these cases may be identified in a timely fashion. We present a case of an ill-appearing patient who had an immediate change in management due to the visualization of RHT soon after arrival to the ED. The diagnosis was confirmed after a cardiology-performed ultrasound (US). This case illustrates the value of the recognition of RHT on FocUS and how US protocols designed for the evaluation of shock and shortness of breath may potentially be expanded to patients in a 'compensated' or 'pre-shock' state to expedite the correct diagnosis and to facilitate more timely management.

Bedside ultrasound in resuscitation and the rapid ultrasound in shock protocol.

Assessment of hemodynamic status in a shock state remains a challenging issue in Emergency Medicine and Critical Care. As the use of invasive hemodynamic monitoring declines, bedside-focused ultrasound has become a valuable tool in the evaluation and management of patients in shock. No longer a means to simply evaluate organ anatomy, ultrasound has expanded to become a rapid and noninvasive method for the assessment of patient physiology. Clinicians caring for critical patients should strongly consider integrating ultrasound into their resuscitation pathways.

The role of bedside ultrasound in the diagnosis of pericardial effusion and cardiac tamponade.

This review article discusses two clinical cases of patients presenting to the emergency department with pericardial effusions. The role of bedside ultrasound in the detection of pericardial effusions is investigated, with special attention to the specific ultrasound features of cardiac tamponade. Through this review, clinicians caring for patients with pericardial effusions will learn to rapidly diagnose this condition directly at the bedside. Clinicians will also learn to differentiate between simple pericardial effusions in contrast to more complicated effusions causing cardiac tamponade. Indications for emergency pericardiocentesis are covered, so that clinicians can rapidly determine which group of patients will benefit from an emergency procedure to drain the effusion.

Emergency department ultrasound by nurse practitioners.

PURPOSE: Bedside ultrasound (u/s) examinations by emergency physicians (EPs) have been integrated into clinical emergency medicine (EM) training programs and the efficacy and success of an introductory u/s training course, based on established guidelines, has been previously described. We used this same course to teach EM nurse practitioners (NPs) bedside u/s and then assessed the adequacy of NP ultrasonography 1 year following the course. DATA SOURCES: Five NPs were included in a standardized 16-h EM u/s training program. Subsequently, the NPs were asked to print consecutive u/s images representative of their clinical assessments. A single qualified EP reviewer assessed images for adequacy. CONCLUSIONS: Five NPs reported 229 u/s examinations, two of which were excluded as nondiagnostic over the 2-month study period. There were 32 inadequate images and 27 "positive" findings. All the positives were correct. Totals per provider were 104, 58, 49, 13, and 3 u/s assessments with 83%, 95%, 84%, 77%, and 100% adequacy of images, respectively. Of the 32 inadequate images, 18 of these were incomplete focused assessment with sonography for trauma (FAST) examinations with a reading of negative for free fluid. IMPLICATIONS FOR PRACTICE: NPs are able to perform focused u/s with a high degree of accuracy, and a 16-h guideline-based course serves as a good introductory foundation.

The RUSH exam: Rapid Ultrasound in SHock in the evaluation of the critically lll.

The RUSH exam (Rapid Ultrasound in SHock examination), presented in this article, represents a comprehensive algorithm for the integration of bedside ultrasound into the care of the patient in shock. By focusing on a stepwise evaluation of the shock patient defined here as "Pump, Tank, and Pipes," clinicians will gain crucial anatomic and physiologic data to better care for these patients.

Diagnosis of diverticulitis by bedside ultrasound in the Emergency Department.

This case report describes a potential novel indication for the use of bedside ultrasound in the Emergency Department. The patient in this case had some of the signs and symptoms of diverticulitis. The "pseudo-kidney" sign, which was thought to represent acute diverticulitis, was appreciated on a rapid, bedside ultrasound and confirmed by computed tomography. Knowledge of the sonographic appearance of diverticulitis may aid emergency physicians in making this diagnosis promptly, and facilitate the appropriate disposition.

Bedside echocardiography in chest trauma.

Bedside US has an established role in the evaluation of chest trauma patients. Transthoracic echocardiography and TEE can be used to obtain critical information at the bedside for many emergent conditions, including the immediate detection of hemopericardium and acute aortic injury. More recent work has demonstrated that US also can be used to detect hemothoraces and pneumothoraces with accuracy. These diagnostic techniques can improve patient outcome and are within the scope of practice of emergency physicians and trauma surgeons. Physicians caring for trauma patients should be familiar with these techniques.

Residency training in emergency ultrasound: fulfilling the mandate.

Although bedside ultrasound is listed in the Model of the Clinical Practice of Emergency Medicine as an integral diagnostic procedure, the manner in which the didactic, hands-on, and experiential components of emergency ultrasound are taught is not specifically prescribed by the Residency Review Committee for Emergency Medicine (RRC-EM) or any single sponsoring group. Seven professional organizations [the American Board of Emergency Medicine (ABEM), the American College of Emergency Medicine (ACEP), the Council of Emergency Medicine Residency Directors (CORD), the Emergency Medicine Residents Association (EMRA), the National Association of EMS Physicians (NAEMSP), the RRC-EM, and the Society for Academic Emergency Medicine (SAEM)] developed the Scope of Training Task Force, with the goal of identifying emerging areas of clinical importance to the specialty of emergency medicine, including emergency department (ED) ultrasound. The Task Force then identified a group of recognized authorities to thoughtfully address the issue of ED ultrasound training. This report represents a consensus of these identified experts on how emergency ultrasound training should be incorporated into emergency medicine residency programs.
