Defibrillating the Data

The TASC trial was the first phase 3 RCT to investigate if therapeutic-dose tinzaparin could shorten acute chest syndrome (ACS) duration in adults with sickle cell disease without pulmonary artery macrothrombosis. The study found that therapeutic-dose tinzaparin reduced time to ACS resolution compared with prophylactic doses, and also resulted in significantly lower opioid consumption. Clinically, this suggests a potential role for higher-dose anticoagulation in managing ACS refractory to current supportive care.

This article provides an overview within the Critical Kids series regarding pediatric emergencies, specifically referencing the PRoMPT trial. The text reviews adult trials comparing crystalloid types for resuscitation in sepsis, noting that SMART showed reduced rates of AKI and death with balanced crystalloids compared to normal saline in critically ill patients. Clinically, this suggests considering balanced crystalloids when managing septic shock in the ED setting.

This study derived and validated the GOTHIC score, a simple risk tool for predicting bloodstream infection using seven variables assessable immediately after ED triage. The score incorporates factors like age \ge 75 years, tachycardia >90 bpm, systolic blood pressure <38^\circC, isolated fever as chief complaint, and protective complaints. This aims to improve prediction accuracy in febrile ED patients where blood cultures are often performed despite low yield.

This article provides practical tips on using ketamine in trauma patients, highlighting its utility for analgesia and procedural sedation while preserving cardiovascular stability. A key recommendation is to consider low-dose ketamine when conventional analgesics have plateaued, as it serves as an excellent opioid-sparing adjunct. Clinicians should ensure all patients receiving ketamine are fully monitored, with capnography being standard practice in the resuscitation room.

This study evaluated the diagnostic accuracy of the Roth score and Dyspnea Severity Score (DSS) for making discharge decisions in patients with exacerbations of COPD presenting to the ED. Both scores demonstrated high sensitivity, suggesting they offer a swift and pragmatic solution for patient disposition. In daily practice, these tools provide reliable, non-invasive bedside cut-offs that can help streamline care and reduce unnecessary resource use.

This study developed an expert consensus definition for paediatric out-of-hospital clinical deterioration (POCD), defining it as progressive or acute worsening identified by observable trends, rather than isolated measurements. Core indicators consistently prioritized across all age groups include airway patency, respiratory rate, work of breathing, oxygen saturation, skin color/perfusion, and level of consciousness. This framework provides a shared standard for prehospital recognition of POCD.

This study investigated strategies to reduce unnecessary CT head utilization for blunt head injury in the ED. The authors found that implementing a multimodal intervention, including an institutional guideline, education, provider feedback, and integrated CDS, was associated with a reduction in CT head studies. Clinicians can apply this by integrating evidence-based guidelines directly into the EHR workflow to guide decision-making.

This article discusses an Electronic Medical Record (EMR) intervention designed to improve opioid management in cancer patients within the Emergency Department (ED). The key finding is that using an EMR-integrated Benzodiazepine/Pain Assessment (BPA) tool was associated with improved ED pain management and reduced hospital admissions. Clinically, this supports integrating such EMR-based tools to promote guideline-concordant, personalized care for cancer-related pain in the ED setting.

This systematic review and meta-analysis assessed the diagnostic accuracy of five-level ED triage systems, including ESI, MTS, CTAS, ATS, and SATS. The findings suggest that reported performance varies across different clinical settings and outcome definitions. This information is relevant for understanding the reliability of current prioritization tools in emergency care.

This meta-analysis compares the Drip-and-Ship (DS) versus Mothership (MS) model for acute ischemic stroke care, stratified by stroke system integration. The key finding is that the MS model demonstrates shorter treatment times and superior functional outcomes compared to DS, irrespective of the level of stroke system integration. Clinically, this suggests favoring the Mothership model approach to optimize patient outcomes in acute stroke management.

This multicenter study compared ventilation parameters across different manual ventilation modes and airway devices during CPR. Key findings show that BVM ventilations have limited efficacy, while asynchronous ETT ventilation generates high airway pressures. Clinically, these results emphasize the need for standard measurement of ventilation parameters in both research and actual resuscitation practice.

A new risk stratification decision tree, KIT-FISTO, was developed and internally validated to predict obstructive acute kidney injury (AKI) in the ED. High-risk features include lumbar, flank, or hypogastric pain, associated with an obstructive AKI risk of approximately 54-55%. The model suggests low risk for most patients (>70%), but external validation is required before clinical use.

This retrospective study described pediatric necrotizing pneumonia (PNP), noting it was diagnosed in 1.6% of hospitalized pneumonia cases. The key findings indicate that *Streptococcus pneumoniae* is the predominant pathogen, and surgical intervention was required in over half of patients due to pleural effusion or persistent infection. Clinically, prolonged fever or respiratory failure after 72 hours on antibiotics warrants evaluation for complications, making chest imaging essential for diagnosis.

This report aims to characterize the incidence, practice patterns, and outcomes associated with awake tracheal intubation performed by emergency physicians within a tertiary-care emergency department. The study focuses specifically on airway interventions in this setting.

This secondary analysis examined associations between homelessness and Hepatitis C Virus (HCV) testing offer, acceptance, seropositivity, and viremia within the DETECT trial. The study highlights that emergency departments are well-positioned to screen for HCV, especially among homeless individuals who are at increased risk and traditionally underserved.

This systematic review and meta-analysis assessed the impact of volume-controlled mechanical ventilation versus manual ventilation during cardiopulmonary resuscitation. The evidence suggests no significant difference in clinical outcomes between these two modes. Clinicians should note that the relative effectiveness of volume-controlled ventilation compared to other mechanical ventilation modes remains uncertain.

This study compared commonly used Early Warning Scores (EWS) against triage clinical judgment for predicting early ICU admission or death among ED patients. The key finding was that EWS did not clearly outperform triage clinical judgment in prediction, with decision curve analysis showing comparable or greater net benefit for clinical judgment. Clinicians should view structured scores and clinical judgment as potentially complementary tools to guide timely escalation of care.

This case report details a rare instance of traumatic uterine rupture in a nonpregnant adolescent following severe blunt trauma. The key argument is the importance of not dismissing subtle uterine findings on initial CT scans, even when pregnancy is excluded. Clinically, this emphasizes considering pelvic MRI when unexplained hemoperitoneum persists after initial stabilization for unstable pelvic fractures.

This study investigated clinician characteristics associated with ordering CT scans for children with very low risk of clinically important TBI. Results found that increased years of experience, lower self-reported risk tolerance, and a smaller proportion of pediatric cases were associated with higher rates of unnecessary CT use in this population. The authors suggest involving providers with greater pediatric expertise to improve imaging decision-making.

A review assessed IN ketamine as a procedural sedation alternative to IV ketamine in pediatric patients, analyzing 150 papers and including eight relevant studies. The evidence suggests IN ketamine has a slightly lower success rate than IV ketamine but remains a useful needle-free option for severely needle-phobic children when discussed with parents.
