BACKGROUND: The prognostic value of point-of-care lung ultrasound has not been evaluated in a large cohort of patients with COVID-19 admitted to general medicine ward in the United States. The aim of this study was to describe lung ultrasound findings and their prognostic value in patients with COVID-19 admitted to internal medicine ward. METHOD: This prospective observational study consecutively enrolled 105 hospitalized participants with COVID-19 at 2 tertiary care centers...

BACKGROUND: Spinal anesthesia using a surface landmark-guided technique can be challenging in patients with anatomical alterations of the lumbar spine; however, it is unclear whether using ultrasonography can decrease the technical difficulties in these populations. We assessed whether an ultrasound-assisted technique could reduce the number of needle passes required for block success compared with the landmark-guided technique in patients with abnormal spinal anatomy. METHODS: Forty-four patients with abnormal spinal anatomy including documented lumbar scoliosis and previous spinal surgery were randomized to receive either surface landmark-guided or preprocedural ultrasound-assisted spinal anesthesia...

PURPOSE OF REVIEW: Point-of-care ultrasound (POCUS) has become an integral component of daily care in the surgical ICU. There have been many novel advancements in the past two decades, too numerous to count. Many are of critical importance to the intensive care physician, whereas others are still accumulating evidence. Without appropriate training, diligence, and incorporation of the ultrasound findings into the whole clinical picture, this technique can be gravely misused. This review examines POCUS use in the surgical ICU, as well as highlights potential hazards and common pitfalls...

PURPOSE OF REVIEW: Critical care echocardiography (CCE) has become an important component of general critical care ultrasonography, and a current review of its performance is presented. RECENT FINDINGS: Basic CCE should be performed as a goal-directed examination to better identify specific signs and to answer important clinical questions concerning acute hemodynamic concerns. It has evolved in the ICU and also in the emergency department not only for improved diagnostic capability but also as an effective part of the triage process...

PURPOSE OF REVIEW: The use of bedside or point-of-care ultrasound (POCUS) in medical emergencies is rapidly becoming more established as an effective acute diagnostic tool. The purpose of this review is to provide an overview of the various techniques currently used that are readily available, as well as several in development. Possible caveats are also addressed. RECENT FINDINGS: Despite its widespread use, definitive studies demonstrating improved patient outcomes are limited...

Peripheral intravenous (PIV) catheter insertion is the most commonly performed procedure in hospitals. Multiple patient factors can make PIV insertion challenging, and ultrasound guidance has been demonstrated to improve the rate of success in these difficult patients. This article outlines the suggested techniques for the ultrasound-guided insertion of PIV catheters, midline catheters, and peripherally inserted central catheters. Illustrative figures and narrative videos demonstrating these techniques are included...

BACKGROUND: In critically ill patients at risk for organ failure, the administration of intravenous fluids has equal chances of resulting in benefit or harm. While the intent of intravenous fluid is to increase cardiac output and oxygen delivery, unwelcome results in those patients who do not increase their cardiac output are tissue edema, hypoxemia, and excess mortality. Here we briefly review bedside methods to assess fluid responsiveness, focusing upon the strengths and pitfalls of echocardiography in spontaneously breathing mechanically ventilated patients as a means to guide fluid management...

Echocardiography is pivotal in the diagnosis and management of the shocked patient. Important characteristics in the setting of shock are that it is non-invasive and can be rapidly applied.In the acute situation a basic study often yields immediate results allowing for the initiation of therapy, while a follow-up advanced study brings the advantage of further refining the diagnosis and providing an in-depth hemodynamic assessment. Competency in basic critical care echocardiography is now regarded as a mandatory part of critical care training with clear guidelines available...

Preprocedural spinal ultrasound appears to decrease the failure rate and complications of neuraxial anesthesia compared to the conventional landmark technique. It is especially beneficial in difficult cases where conventional palpation technique may fail. We recently encountered a parturient with multiple lumbar and cervical spinal metastatic lesions presenting for cesarean section in the third trimester. We used spinal ultrasound to define the appropriate intervertebral space and measure the distance to the ligamentum flavum-dura mater complex...

BACKGROUND/PURPOSE: Internal jugular vein (IJV) access is commonly performed in neonates and infants with open cut-down method. We report the results of ultrasound guided percutaneous venous access in newborn patients in the neonatal intensive care unit (NICU). METHODS: We retrospectively examined the medical records of NICU patients who underwent therapeutic percutaneous IJV access under ultrasound guidance from October 2015 to May 2015. Under general anesthesia, IJV was punctured with a 21 gauge needle after identification by ultrasound...

Unexpected acute respiratory failure after anesthesia is a diagnostic challenge: residual neuromuscular blockade, bronchial hyperresponsiveness, laryngospasm, atelectasis, aspiration pneumonitis, and other more uncommon causes should be taken into account at diagnosis. Lung ultrasound and echocardiography are diagnostic tools that would provide the differential diagnosis. We report a suspected case of a transfusion related acute lung injury (TRALI) following administration of platelets. The usefulness of lung and cardiac ultrasound is discussed to facilitate the challenging diagnosis of the acute early postoperative respiratory failure...

Ultrasound guidance currently represents the gold standard for regional anesthesia. In particular for lower extremity blocks, despite the heterogeneity and the lack of large randomized controlled trials, current literature shows a modest improvement in block onset and quality compared with other localization techniques. This review aims to present the most recent findings on the application of ultrasound guidance for each single lower extremity approach.

BACKGROUND: Unrecognized malposition of the endotracheal tube (ETT) can lead to severe complications in patients under general anesthesia. The focus of this double-blinded randomized study was to assess the accuracy of point-of-care ultrasound in verifying the correct position of the ETT and to compare it with the accuracy of auscultation. METHODS: Forty-two adult patients requiring general anesthesia with ETT were consented. Patients were randomized to right main bronchus, left main bronchus, or tracheal intubation...

INTRODUCTION: In critical care, early diagnosis and correct treatment are of the utmost importance. Focused ultrasonography has gained acceptance as a pivotal tool for this by elucidating the underlying pathology. For example, massive pulmonary embolism is characterised by right ventricular dilatation. However, theoretically these characteristics might also be generated by asphyxia and the consequent hypoxia. We aimed to evaluate the ultrasonographic characteristics of asphyxia in a porcine model...

BACKGROUND: Ultrasonography (performed by means of a four-quadrant, focused assessment of sonography for trauma (FAST)) is regarded as a key instrument for the initial assessment of patients with suspected blunt abdominal and thoraco-abdominal trauma in the emergency department setting. FAST has a high specificity but low sensitivity in detecting and excluding visceral injuries. Proponents of FAST argue that ultrasound-based clinical pathways enhance the speed of primary trauma assessment, reduce the number of unnecessary multi-detector computed tomography (MDCT) scans, and enable quicker triage to surgical and non-surgical care...

PURPOSE: In light of point-of-care ultrasonography's (POCUS) recent rise in popularity, assessment of its impact on diagnosis and treatment in the intensive care unit (ICU) is of key importance. METHODS: Ultrasound examinations were collected through an ultrasound reporting software in 6 multidisciplinary ICU units from 3 university hospitals in Canada and the United States. This database included a self-reporting questionnaire to assess the impact of the ultrasound findings on diagnosis and treatment...

OBJECTIVE: Although ultrasound guidance for subclavian vein catheterization has been well described, evidence for its use has not been comprehensively appraised. Thus, we conducted a systematic review and meta-analysis to determine whether ultrasound guidance of subclavian vein catheterization reduces catheterization failures and adverse events compared to the traditional "blind" landmark method. All forms of ultrasound were included (dynamic 2D ultrasound, static 2D ultrasound, and Doppler)...
