Defibrillating the Data

This systematic review synthesized evidence regarding whether keeping a patient in a non-supine position improves first-pass success rates during emergency department (ED) intubation. The authors searched multiple databases, identifying six prospective studies, including two randomized controlled trials, to assess this practice. Overall, the meta-analysis found a consistent positive association between maintaining patient angulation and achieving successful intubation on the first attempt across three of the included studies. These findings suggest that incorporating inclined positioning into standard ED protocols may improve procedural outcomes for airway management.

This month's Resuscitation and Acute Critical Care Literature review from EMCrit touches on several high-yield topics relevant to resuscitation practice. Specifically, it addresses the efficacy of administering prehospital whole blood products, which is always a point of debate in acute care settings. Another key area reviewed concerns potential damage to defibrillators resulting from direct current discharge (DSD), an important consideration for equipment management. Furthermore, there are updates and discussions regarding adenosine use protocols for stable versus unstable supraventricular tachycardia (SVT). Given the breadth of resuscitation topics covered, this review offers a good snapshot of evolving guidelines and evidence in critical care.

The TASC trial represents a significant step forward by being the first phase 3 randomized controlled trial to directly compare therapeutic versus prophylactic-dose tinzaparin in adults with sickle cell disease presenting with acute chest syndrome (ACS) but without evidence of pulmonary artery macrothrombosis. The primary question addressed was whether using higher doses of anticoagulation could accelerate the resolution of ACS compared to standard prophylactic dosing. The results were quite compelling, demonstrating that therapeutic-dose tinzaparin successfully reduced the overall time required for ACS resolution and also led to a statistically significant decrease in opioid consumption among the patients studied. This suggests that simply maintaining prophylaxis might not be optimal care when managing this acute complication.

This update in the Critical Kids series focuses on pediatric emergencies, specifically reviewing the evidence from the PRoMPT trial and drawing parallels to adult resuscitation literature regarding crystalloid choice in septic shock. While the article itself is an overview referencing the PRoMPT trial, it highlights relevant findings from adult studies, such as SMART, which demonstrated that using balanced crystalloids versus normal saline was associated with lower rates of acute kidney injury and mortality in critically ill adults. The general takeaway for pediatric practice seems to be a consideration of these fluid resuscitation principles when managing septic shock in the emergency department setting.

This multisite US study focused on validating and optimizing the utility of an existing point-of-care (POC) high sensitivity troponin I (hs-cTnI) algorithm, specifically a 0/2-hour approach. The authors assessed both the original Australian protocol and an optimized version across multiple emergency department settings in the United States. The key finding is that both algorithms demonstrated robust performance metrics, notably maintaining very high negative predictive values (NPV). From a clinical standpoint, implementing the optimized algorithm appears to boost diagnostic efficacy while preserving excellent NPV, suggesting its strong role in rapid risk stratification within the ED setting.

This retrospective study introduces the GOTHIC score, a novel, easily calculable tool designed to predict bloodstream infection risk in febrile emergency department patients based on variables available immediately upon triage. The authors derived and validated this score using data from two EDs over 2021, analyzing factors like age ≥75 years, tachycardia >90 beats per minute, systolic blood pressure <38 degrees Celsius, isolated fever as the chief complaint, and protective complaints. They found that incorporating these seven variables into a logistic regression model yielded a predictive score intended to improve accuracy in settings where blood cultures are frequently drawn despite potentially low yield. The inclusion of specific factors like age and hemodynamic instability suggests a targeted approach for resource allocation.

This brief review covers the critical scenario known as Can't Intubate Can't Oxygenate (CICO), which represents a profound failure of all standard upper airway rescue techniques, including face mask ventilation, supraglottic device placement, and tracheal intubation. The core message is that when these established 'lifelines' fail to secure adequate alveolar oxygenation, the definitive management pathway shifts immediately to emergency front-of-neck access (FONA). It emphasizes that recognizing this failure state requires continuous reassessment of all implemented airway strategies rather than simply progressing through a checklist of maneuvers. Therefore, maintaining readiness for an emergent surgical airway approach is paramount throughout the entire resuscitation effort.

This practical guide from St Emlyn's focuses specifically on optimizing the use of ketamine within the complex setting of trauma resuscitation. It serves as a comprehensive resource covering its roles in both analgesia and procedural sedation, with a particular emphasis on maintaining cardiovascular stability during these interventions. The core message revolves around leveraging low-dose ketamine when standard analgesic regimens begin to plateau, positioning it as a valuable opioid-sparing adjunct for the emergency physician. Crucially, the article stresses that despite its utility, continuous monitoring is non-negotiable; capnography should be considered standard practice within the resuscitation bay whenever administering ketamine.

This article evaluates two scoring systems, the Roth score and the Dyspnea Severity Score (DSS), to help guide discharge decisions for patients presenting to the emergency department with exacerbations of COPD. The authors found that both scores exhibit high sensitivity when used in this setting. This suggests they represent a quick, pragmatic tool for determining whether a patient can safely leave the ED. Essentially, these tools offer objective, non-invasive bedside cutoffs intended to standardize care and optimize resource use during acute COPD exacerbations.

This multicenter observational cohort study provided a detailed comparison of various ventilation parameters encountered during cardiopulmonary resuscitation, looking at different manual ventilation modes and airway devices. The authors found significant variability in these parameters depending on the technique used. Notably, they reported that bag-valve mask (BVM) ventilations appear to have limited overall efficacy compared to other methods. Furthermore, asynchronous endotracheal tube (ETT) ventilation was associated with generating high airway pressures, while spontaneous assisted ventilation (SAD) provided more consistent tidal volumes and pressures across different modes, though leakage was observed to increase over time. Overall, the study underscores that current practices result in a wide spectrum of measurable ventilation parameters during CPR.

This piece addresses the persistent issue of overutilization of computed tomography (CT) scans for blunt head injury in the emergency department setting. The authors investigated the effectiveness of a comprehensive, multimodal intervention designed to curb unnecessary imaging. Their findings suggest that simply implementing an institutional guideline is insufficient on its own; rather, combining this guideline with educational components, structured provider feedback, and integration into the clinical decision support (CDS) system yields measurable reductions in CT head utilization. This approach suggests that process change requires a multi-pronged strategy involving education, accountability, and workflow integration to be truly impactful.

This piece dives into the application of the YEARS protocol for ruling out pulmonary embolism (PE) using a D-dimer threshold, specifically raising flags regarding its utility in patients with active malignancy. While the Hydra trial demonstrated comparable 90-day mortality rates between diagnostic strategies, the authors caution that the YEARS score's ability to accurately risk-stratify this particular cancer cohort seems questionable when compared to previous findings. The core concern revolves around whether relying on a simple D-dimer cutoff remains reliable enough for guiding management decisions in immunocompromised or actively cancerous patients. It suggests that while the protocol is generally useful, its application needs careful consideration when malignancy is present.

This report provides an observational characterization of awake tracheal intubation performed by emergency physicians within the demanding environment of a tertiary care emergency department. The authors analyzed data from the Airway Interventions Registry and associated databases to map out how often these procedures occur, what the typical practice patterns look like, and what the resulting clinical outcomes are. Given that rapid sequence induction is often preferred in many settings, understanding the true utility and safety profile of awake techniques performed by ED staff is quite relevant for optimizing local protocols. The findings help paint a picture of the current landscape regarding this specific airway intervention modality within acute care.

This retrospective analysis compared the risk of intracranial hemorrhage (ICH) following minor head trauma in patients managed on direct oral anticoagulants (DOACs), warfarin, or no anticoagulation. The primary takeaway is that DOAC use appeared to confer a better safety profile compared to warfarin when these patients sustained minor head injuries. This finding suggests a potential shift in management strategy for the anticoagulated patient presenting after low-energy trauma. While the data points toward reduced risk with DOACs versus warfarin, it's important to remember this is observational research.

This secondary analysis from the DETECT trial focused on characterizing the association between experiencing homelessness and various aspects of Hepatitis C Virus (HCV) management within the emergency department setting. The authors specifically examined how being homeless related to the offer of HCV testing, patient acceptance of that testing, subsequent seropositivity rates, and evidence of active viremia among this high-risk population. Overall, the findings strongly reinforce the utility of EDs as a critical point of care for identifying undiagnosed or untreated HCV in individuals who are often marginalized and historically underserved by routine healthcare screening efforts.

This case report details an unusual presentation of traumatic uterine rupture in a nonpregnant adolescent following severe blunt trauma, which is quite rare given that most reported cases occur during pregnancy. The authors highlight the potential for this diagnosis to be missed because clinicians often default to thinking about gestation when evaluating pelvic trauma. The key takeaway from this case is the need for vigilance regarding subtle findings on imaging even after ruling out pregnancy. They suggest that if unexplained hemoperitoneum persists following initial stabilization for unstable pelvic fractures, considering a more sensitive modality like pelvic MRI might be warranted.

This review synthesized data from numerous papers to evaluate the role of intranasal (IN) ketamine as a procedural sedation alternative to intravenous (IV) ketamine in the pediatric emergency department setting. The authors analyzed a large body of literature, ultimately focusing on eight relevant studies for their conclusions. They found that while IN ketamine is an appealing needle-free option, its success rate appears marginally lower compared to traditional IV administration. Despite this slight deficit in efficacy, the review suggests it remains a valuable tool, particularly when managing children with significant needle phobias.

This paper introduces the KIT-FISTO model, a newly developed risk stratification decision tree designed to help emergency physicians predict obstructive acute kidney injury (AKI) in the ED setting. The authors derived and internally validated this tool using retrospective data from patients presenting with AKI of any KDIGO stage. They found that the presence of lumbar, flank, or hypogastric pain strongly correlates with a high risk of obstructive AKI, estimating the probability at around 54-55%. Conversely, patients without these specific symptoms but possessing other risk factors like prior urinary tract surgery or prostatic hyperplasia fall into a moderate risk category. The model appears highly sensitive for identifying low-risk patients, suggesting that most individuals are unlikely to have an obstructive etiology. However, the authors rightly caution that this tool has only undergone internal validation and requires external, prospective testing before it can be considered reliable enough for routine clinical use.

This systematic review synthesized the current literature regarding the use of high-flow nasal cannula (HFNC) specifically to manage oxygenation during the apneic period encountered during rapid sequence induction (RSI) in the emergency department setting. The authors assessed whether providing continuous, high-flow oxygen could improve oxygenation status compared to standard care during this critical window. While some individual studies suggested that HFNC might allow for a longer safe duration of apnea without significant desaturation, the review noted a lack of evidence demonstrating any impact on major clinical endpoints such as overall mortality or the incidence of desaturation events. Overall, the conclusion suggests that while it remains an available oxygenation adjunct to consider during RSI in the ED, the data supporting a definitive, clinically meaningful benefit are currently limited.

This retrospective review details the clinical spectrum, microbiology, and management strategies for pediatric necrotizing pneumonia (PNP). The authors report that PNP accounts for a relatively small percentage of hospitalized pneumonia cases, specifically noting its diagnosis in 1.6% of patients seen at their tertiary center. They established that *Streptococcus pneumoniae* remains the most common causative organism. A key clinical observation is the high rate of complications requiring intervention; over half of the pediatric patients needed surgical management due to significant pleural effusion or persistent underlying infection. The authors emphasize a critical time point for reassessment, suggesting that prolonged fever or respiratory failure persisting beyond 72 hours despite appropriate antibiotic therapy mandates thorough investigation for complicating processes.
