Crit Care 2016 08 15;20(1):227. Epub 2016 Aug 15.
Micah R Whitson, Paul H Mayo
Point-of-care ultrasonography (POCUS) is a useful imaging technique for the emergency medicine (EM) physician. Because of its growing use in EM, this article will summarize the historical development, the scope of practice, and some evidence supporting the current applications of POCUS in the adult emergency department. Bedside ultrasonography in the emergency department shares clinical applications with critical care ultrasonography, including goal-directed echocardiography, echocardiography during cardiac arrest, thoracic ultrasonography, evaluation for deep vein thrombosis and pulmonary embolism, screening abdominal ultrasonography, ultrasonography in trauma, and guidance of procedures with ultrasonography.

Ocular emergencies account for 2-3% of all emergency department (ED) visits. Sonographic evaluation of the eye offers a very useful diagnostic tool in the ED. In the ED setting, ocular ultrasound could identify a retinal detachment, or a massive vitreous hemorrhage, and the training for emergency medicine practitioners is quite easy.

Ocular Injuries: New Strategies In Emergency Department Management.

Emerg Med Pract 2015 Nov 1;17(11):1-21; quiz 21-2. Epub 2015 Nov 1.
Anne M Messman
Ocular injuries are common in the emergency department, and they are the most frequent cause of noncongenital monocular blindness in children and adults. This review provides evidence-based recommendations for the diagnosis, treatment, and disposition of patients with all types of ocular trauma, including pain management, the use of antibiotics, cycloplegics, steroids, antifibrinolytics, and patching. Bedside ocular ultrasound has profoundly expanded diagnostic capability, particularly for the multiply injured patient, and routine management and disposition of patients with corneal abrasions has evolved significantly as well.

CNS Tuberculosis can manifest as meningitis, arachnoiditis and a tuberculoma. The rupture of a tubercle into the subarachnoid space leads to Tuberculosis Meningitis (TBME); the resulting hypersensitivity reaction can lead to an elevation of the intracranial pressure and hydrocephalus. While bedside optic nerve sheath diameter (ONSD) ultrasonography (USG) can be a sensitive screening test for elevated intracranial pressure in adult head injury, little is known regarding ONSD measurements in Tuberculosis Meningitis.

Retinopathy of prematurity (ROP) remains a significant threat to vision for extremely premature infants despite the availability of therapeutic modalities capable, in most cases, of managing this disorder. It has been shown in many controlled trials that application of therapies at the appropriate time is essential to successful outcomes in premature infants affected by ROP. Bedside binocular indirect ophthalmoscopy has been the standard technique for diagnosis and monitoring of ROP in these patients.

The aim was to evaluate efficacy of optic nerve sheath diameter (ONSD) by ultrasound as a noninvasive method for detecting raised intracranial pressure (ICP) in intensive care unit, to compare with computed tomography/magnetic resonance imaging (MRI) findings of raised ICP and to prognosticate ONSD value with treatment.
We conducted a prospective, observational study on 101 adults by including 41 healthy individuals in group A as control and 60 patients in group B admitted with fever, headache, vomiting, and altered sensorium. We examined them in supine position using 10 MHz linear array probe on closed eyelid.

The integration of bedside ultrasound into medical school curricula is limited by the availability of skilled faculty instructors. Peer mentors have been utilized successfully to teach clinical and procedural skills and may serve as a valuable resource for potential ultrasound instructors. We describe a method to train senior medical students as peer instructors for a combined ultrasound/physical exam curriculum and assessed junior medical students' perceptions of peer instruction relative to faculty.

Bedside ocular ultrasound.

Crit Care Clin 2014 Apr 12;30(2):227-41, v. Epub 2013 Dec 12.
Pedro J Roque, Nicholas Hatch, Laurel Barr, Teresa S Wu
Many ocular emergencies are difficult to diagnose in the emergency setting with conventional physical examination tools. Additionally, persistent efforts to re-examine the eye may be deleterious to a patient's overall condition. Ultrasound is an important tool because it affords physicians a rapid, portable, accurate, and dynamic tool for evaluation of a variety of ocular and orbital diseases.

Cerebral infarction presenting with isolated vertigo remains a diagnostic challenge. To define the clinical characteristics of unilateral infarctions restricted to the vestibular nuclei, two patients with isolated unilateral vestibular nuclear infarction had bedside and laboratory evaluation of the ocular motor and vestibular function, including video-oculography, bithermal caloric irrigation, the head impulse test (HIT) using magnetic scleral coils, and cervical and ocular vestibular-evoked myogenic potentials (VEMPs). We also reviewed the literature on isolated vertigo from lesions restricted to the vestibular nuclei, and analyzed the clinical features of seven additional patients.

The use of point-of-care ultrasound in the emergency department has expanded considerably in recent years, allowing enhanced evaluation of the patient with an emergent eye or vision complaint. The technique is simple and quick to perform, and can yield clinical information that may not be readily obtainable through physical or slit-lamp exams. Ocular bedside sonography can aid in the diagnosis of retinal and vitreous hemorrhage, retinal and vitreous detachments, ocular infections, foreign bodies, retrobulbar hematoma, or ocular vascular pathology.

Increases in intracranial pressure (ICP) after head trauma require a rapid recognition to allow for adequate treatments. The aim of this study was to determine whether dilation of the optic nerve sheath, as detected by ocular ultrasound at the bedside, could reliably identify increases in ICP assessed with an intraparenchymal probe in adult head trauma patients.
Eleven head trauma injured adult patients admitted to the intensive care unit with a Glasgow Coma Scale score ≤8, with cerebral contusion confirmed by computed tomography scan, and that required invasive ICP monitoring, were enrolled in the study.

Retinal detachment is an ocular emergency posing diagnostic difficulty for the emergency practitioner. Direct fundoscopy and visual field testing are difficult to perform and do not completely rule out retinal detachment. Ophthalmologists use ocular ultrasound to enhance their clinical acumen in detecting retinal detachments (RD), and bedside ultrasound capability is readily available to many emergency practitioners (EP).
