Ultrasound is becoming a valuable diagnostic tool in the armamentarium of thoracic surgeons. We report its use to follow stent placement in the laryngotracheal position for management of life-threatening neoplastic obstruction. For this purpose, a 15-MHz linear probe was placed in the midline at the level of the cricoid cartilage. Ultrasound performed daily at bedside showed normal movement of vocal folds and no stent dislocation. This strategy may be an alternative to computed tomography scan or endoscopy to follow stent placement in extrathoracic airways...

REVIEW
Jacob A M Stadler, Savvas Andronikou, Heather J Zar
Ultrasound (US) has been proposed as an alternative first-line imaging modality to diagnose community-acquired pneumonia in children. Lung US has the potential benefits over chest radiography of being radiation free, subject to fewer regulatory requirements, relatively lower cost and with immediate bedside availability of results. However, the uptake of lung US into clinical practice has been slow and it is not yet included in clinical guidelines for community-acquired pneumonia in children. The aim of this review is to give an overview of the equipment and techniques used to perform lung US in children with suspected pneumonia and the interpretation of relevant sonographic findings...

OBJECTIVE: Ultrasound provides accessible imaging for bedside diagnostics and procedural guidance, but may lead to misdiagnosis in untrained users. The main objective of this study was to determine observed and self-perceived competence with critical care ultrasound in graduated general surgery residents. DESIGN: The design of this study was a retrospective review. Ultrasound training program records were reviewed for number of prior ultrasound examinations performed, self-perceived competence, observed competence on faculty examinations, and intended future use of individual critical care ultrasound examinations...

In the unconscious patient, there is a diagnostic void between the neurologic physical exam, and more invasive, costly and potentially harmful investigations. Transcranial color-coded sonography and two-dimensional transcranial Doppler imaging of the brain have the potential to be a middle ground to bridge this gap for certain diagnoses. With the increasing availability of point-of-care ultrasound devices, coupled with the need for rapid diagnosis of deteriorating neurologic patients, intensivists may be trained to perform point-of-care transcranial Doppler at the bedside...

Many children frequently fail extubation or require a prolonged period of positive pressure ventilation support after cardiac surgery. Pediatric cardiac Intensive Care Unit (PCICU) ultrasound (US) stands as a simple, basic bedside tool that can be performed by trained intensivists for the diagnosis with immediate implication on therapeutic decisions in multiple scenarios that physicians may face in PCICU. Bedside US is widely available, convenient, and inexpensive. This educational article based mainly on our own experience is highlighting the role of US in detecting the most common causes of respiratory weaning difficulties and extubation failure in postoperative cardiac children through proposed illustration and algorithm...

Point of care ultrasonography and the related focused assessment with sonography for trauma protocol, if performed by experienced physicians, is a highly sensitive examination, and specific for the detection of free fluids. Different systems and methods have been proposed for training, including simulation as one of the most efficient. This paper presents an ultrasound training system, specifically designed to be used during bedside high fidelity simulation scenarios, that could facilitate the learning process...

Ultrasound (US) performed at the point of care has found fertile ground in perioperative medicine. In the hands of anesthesiologists, transesophageal echocardiography (TEE) has become established as a powerful diagnostic and monitoring tool in the perioperative care of cardiac and non-cardiac patients. A number of point-of-care US (POCUS) applications are relevant to perioperative care, including airway, cardiac, lung and gastric US. Although guidelines exist to define the scope of practice for basic and advanced TEE, there remains a lack of such guidelines for perioperative point-of-care ultrasound (POCUS), despite a number of recent calls for action in the academic anesthesia community...

Many hospitalists are routinely granted hospital privileges to perform invasive bedside procedures, but criteria for privileging are not well described. We conducted a survey of 21 hospitalist procedure experts from the Society of Hospital Medicine Point-of-Care Ultrasound Task Force to better understand current privileging practices for bedside procedures and how those practices are perceived. Only half of all experts reported their hospitals require a minimum number of procedures performed to grant initial (48%) and ongoing (52%) privileges for bedside procedures...

Nowadays point-of-care ultrasound (POCUS) is considered indispensable for critical care and emergency physicians. POCUS is a noninvasive tool, can be done at the bedside, leads to instant diagnostic information and is safe in terms of radiation. POCUS could also be very suitable for internists in the field of acute internal medicine. There are differences between European internists in the use of POCUS from no use at all to more outlined educational programs. In literature there are examples of comprehensive POCUS guidelines which could serve as an example for the European Federation of Internal Medicine (EFIM)...

BACKGROUND: Patients with intra-abdominal infections need to achieve adequate hemodynamic status before being taken to the operating room. Multiple parameters (urinary output [UOP], vital signs, inferior vena cava collapsibility index, and central venous pressure) may be used to assess hemodynamic response to fluid resuscitation, but the options are few in limited-resource settings. This study aimed at assessing if a bedside-performed ultrasound to assess the inferior vena cava collapsibility index is superior to UOP in assessing hemodynamic response to fluid resuscitation...

PURPOSE: Pulmonary ultrasound (PU) examination at the point-of-care can rapidly identify the etiology of acute respiratory failure (ARF) and assess treatment response. The often-subjective classification of PU abnormalities makes it difficult to document change over time and communicate findings across providers. The study goal was to develop a simple, PU scoring system that would allow for standardized documentation, have high interprovider agreement, and correlate with clinical metrics...

In recent years, point-of-care ultrasound has become a useful technique for assisting in rapid diagnosis or exclusion of pneumothorax. It has been shown to have excellent sensitivity and specificity. Despite this, we present a case of a large pneumothorax that was not detected by bedside ultrasound. We consider the reasons for failure and discuss pitfalls and limitations described in the literature.

We present here the first case of successful management via preoperative ultrasonographic (US) study to detect a distant spreading of Fournier's gangrene (FG), which was happened in a 75-year-old man. US study showed the necrotizing infection in the periumbilical region distant 22 cm from the genital tract. A target incision of this periumbilical area and debridement of necrotic tissues was made. Computed tomography (CT) is superior to ultrasonography to confirm the diagnosis of FG and support in surgical management, but a CT evaluation in patients with FG may be limited by the frequent presence of concurrent acute renal failure or patient hemodynamic instability...

Ultrasound perfusion imaging (UPI) can be used for the quantification of cerebral perfusion. In a neuro-intensive care setting, repeated measurements are required to evaluate changes in cerebral perfusion and monitor therapy. The aim of this study was to determine the repeatability of UPI in quantification of cerebral perfusion. UPI measurement of cerebral perfusion was performed three times in healthy patients. The coefficients of variation of the three bolus injections were calculated for both time- and volume-derived perfusion parameters in the macro- and microcirculation...

Contrast-enhanced ultrasound (CEUS) has been suggested as a new method to measure cerebral perfusion in patients with acute brain injury. In this systematic review, the tolerability, repeatability, reproducibility and accuracy of different CEUS techniques for the quantification of cerebral perfusion were assessed. We selected studies published between January 1994 and March 2017 using CEUS to measure cerebral perfusion. We included 43 studies (bolus kinetics n = 31, refill kinetics n = 6, depletion kinetics n = 6) with a total of 861 patients...
