Rethinking Blood Thinners: Do Mild Brain Injuries Need Maxi Care?

The Brain Injury Guidelines (BIG) classify traumatic brain injuries (TBIs) into three tiers to dictate treatment. Patients taking pre-injury blood thinners (anticoagulants or antiplatelets) are automatically upgraded to the... read more

Blood, Sweat, and the ICU: Conquering Emergencies in Hematological Malignancies

Breakthroughs in cancer therapies and supportive care have dramatically improved life expectancy for patients with hematological malignancies (HM). However, living longer means more patients are surviving long enough to encounter... read more

The Promise and Pitfalls of Bedside Muscle Ultrasound in the ICU

Evaluating muscle wasting and intensive care unit-acquired weakness (ICUAW) is critical, yet traditional methods fall short: computed tomography (CT) scans require risky patient transport, and standard physical exams require... read more

Electrical Impedance Tomography for PEEP Titration in ARDS Patients

ARDS patients may benefit from electrical impedance tomography (EIT)-guided positive end-expiratory pressure (PEEP) titration. The real-time bedside assessment of regional ventilation provided by EIT may result in improved... read more

POCUS-first vs. CT-first Approach on ED LOS in Patients with Acute Cholecystitis

While point-of-care ultrasound (PoCUS)-first and computed tomography (CT)-first approaches resulted in comparable emergency department (ED) length of stay (LOS) and time to surgical consultation for patients with mild AC,... read more

Atypical Presentation of Pulmonary Embolism in Patients with Refractory Hypoxemia and Dyspnea

Pulmonary embolism (PE) should be strongly considered in patients presenting with refractory hypoxemia and dyspnea, even in the absence of clinical signs of deep vein thrombosis (DVT). This study highlights the importance... read more

Improving Patient Outcomes: Sepsis Protocols and Rapid Host Response Technologies

Patients come into the emergency department (ED) with symptoms, not diagnoses. That’s when time is of the essence. Clinicians must quickly triage patients and establish an appropriate care pathway to obtain the best possible... read more

Veno-Arterial-Venous ECMO in a Patient Undergoing Dialysis and Having Cardiopulmonary Failure Due to COVID-19

COVID-19 can cause cardiomyopathy, a rare cardiovascular disorder that can lead to cardiogenic shock. The cardiac and respiratory symptoms may not occur simultaneously, and it is possible to switch to veno-arterial-venous... read more

Can Clinicians Identify CAP on Ultralow-dose CT?

This study found that clinicians could assess chest ULD-CTs for community-acquired pneumonia (CAP) with high, but not perfect, diagnostic accuracy using an ED radiologist’s assessments as reference standard. Interrater... read more

The Hidden Value of MRI: Modifying Treatment Decisions in C-spine Injuries

This study provides a critical evaluation of the implications of additional magnetic resonance imaging (MRI) use in the diagnosis of c-spine injuries. We have demonstrated that an adjunctive MRI extends patients' ED stays,... read more

Chest Computed Tomography Severity Score at ICU Admission and Respiratory Outcomes

COVID-19 patients with >50% lung involvement on Chest-CT admission presented higher chances to stay longer on invasive mechanical ventilation and more chances to developed ventilator-associated pneumonia. 121 patients... read more

Efficacy of High-Flow Nasal Cannula Oxygen Therapy in Patients with AHRF

This study suggests that high-flow nasal cannula (HFNC) therapy in general respiratory wards may be a potential rescue therapy for patients with respiratory failure. Electrical impedance tomography (EIT) potentially monitors... read more

The Hemodynamics of Adrenal Veins with Four-dimensional CT Using Quantitative Time-density Curve

Present study quantitatively analyzed adrenal venous flow using four-dimensional computed tomography (4D CT). We reviewed 4D CT images of 55 patients [mean age, 52 years ± 11 (standard deviation); 23 females] who underwent... read more

Protective Ventilation

As ventilator induced lung injury (VILI) importantly impacts outcome of mechanically ventilated patients, even in those without lung injury, it follows that those caring for the critically ill should apply protective ventilatory... read more

Pulmonary Aeration and Posterior Collapse Assessed by Electrical Impedance Tomography in Healthy Children

The aim of this study was to evaluate the changes in the lung aeration estimated by electrical impedance tomography as the end-expiratory lung impedance after anesthesia induction in pediatric patients. This was a prospective,... read more

Developing a Decision Instrument to Guide Abdominal-pelvic Imaging of Blunt Trauma Patients

Although computed tomography (CT) of the abdomen and pelvis (A/P) can provide crucial information for managing blunt trauma patients, liberal and indiscriminant imaging is expensive, can delay critical interventions, and... read more

Lung Ultrasonography Beyond the Diagnosis of Pediatrics Pneumonia

Pneumonia is a prevalent disease with considerable morbidity and mortality among the pediatric population. Early diagnosis and swift commencement of the correct treatment are vital for a favorable clinical outcome. Along... read more

High-dose vs. Low-dose Prednisolone in post-COVID-19 Patients

In some patients, respiratory symptoms and imaging abnormalities persist after acute coronavirus disease 2019 (COVID-19) pneumonia. The chest computed tomography (CT) generally shows diffuse parenchymal lung abnormalities... read more

Preoperative POCUS to Identify Frailty and Predict Postoperative Outcomes

Similar to computed tomography measurements of psoas muscle area, preoperative ultrasound measurements of quadriceps depth shows promise in discriminating between frail and not-frail patients before surgery. It was also associated... read more

Rapidly Progressive Brain Atrophy in Septic ICU Patients

Many ICU patients with severe sepsis who developed prolonged mental status changes and neurological sequelae showed signs of brain atrophy. Patients with rapidly progressive brain atrophy were more likely to have required... read more

Predicting Adverse Outcomes in COVID-19 Patients Using BV5%

Evidence suggests that vascular inflammation and thrombosis may be important drivers of poor clinical outcomes in patients with COVID-19. We hypothesized that a significant decrease in the percentage of blood vessels with... read more

POCUS Diagnosis of Medial Plantar Artery Pseudoaneurysm Secondary to Penetrating Injury

Pseudoaneurysms of the foot are rare and can occur from a range of etiologies, including laceration from a foreign body. The majority of reported cases have been diagnosed by computed tomography, magnetic resonance imaging,... read more
