From Hyperkalemia Protocols to Community Triage: Today's Focus

The spectrum of acute care today ranges from managing life-threatening electrolyte derangements to optimizing resource use in the community. For acute hyperkalemia, the message remains clear: stabilize the myocardium with calcium if ECG changes are present or potassium hits 6.5 mmol/L or higher. While insulin-glucose remains central for shifting potassium, don't forget the added utility of inhaled beta-agonists, and critically, always monitor for subsequent hypoglycemia.

In other areas, the evidence is pushing us toward nuanced, context-specific algorithms. When managing a crashing pulmonary embolism, integrating the latest AHA consensus into a streamlined, bedside algorithm for thrombolysis versus thrombectomy is proving invaluable. Similarly, for undifferentiated poisoning, adopting a systematic, toxidromic approach—considering the potential toxicokinetics—is the best initial framework until a definitive diagnosis emerges.

Furthermore, we see operational shifts in care delivery. For community head injuries, senior physician input outside the traditional ED setting is becoming a viable model, especially for anticoagulated patients. Even in pediatric non-shockable cardiac arrest, the sequence of advanced airway management versus epinephrine administration appears less critical than immediate clinical feasibility. These varied updates underscore that while guidelines are constantly refining, the core skill remains synthesizing multiple, sometimes conflicting, pieces of data into a cohesive, actionable plan at the bedside.

Acute hyperkalaemia in emergency care: evidence-based approaches

This review synthesizes the current evidence base for managing acute hyperkalemia in the ED, emphasizing that timely intervention is crucial to prevent life-threatening cardiac arrhythmias. The core management principles revolve around stabilizing the myocardium with intravenous calcium salts, which is indicated for patients presenting with ECG changes or a potassium level of 6.5 mmol/L or higher. Insulin-glucose therapy is a mainstay for shifting potassium intracellularly, but clinicians must remain vigilant regarding the risk of subsequent hypoglycemia, especially in non-diabetic patients. The authors also highlight the utility of inhaled beta-agonists, like salbutamol, which offer a synergistic effect when combined with insulin. Furthermore, the review cautions against outdated practices, noting that sodium polystyrene sulfonate is no longer recommended, while newer binders require more acute care validation.

When managing acute hyperkalemia, prioritize calcium administration if ECG changes are present or K+ ≥ 6.5 mmol/L. Remember that insulin-glucose remains key for shifting potassium, but always have glucose monitoring readily available to prevent hypoglycemia. Consider adding inhaled beta-agonists to the insulin regimen for enhanced effect, and reserve sodium bicarbonate use for specific acidosis scenarios.

Clinical decision rules for obtaining chest radiography in adult patients presenting to the emergency department with non-traumatic chest pain: a systematic review and meta-analysis

This systematic review and meta-analysis tackled the resource drain caused by routine chest radiography in non-traumatic chest pain patients, noting that while imaging is used frequently, it yields actionable findings in very few cases. The authors pooled data from several studies to compare existing clinical decision rules, specifically evaluating the Hess and Rothrock criteria. The meta-analysis revealed that while the Hess rule demonstrated higher sensitivity, the overall evidence base is significantly limited by the small number of included studies, high heterogeneity, and the reliance on retrospective cohort data. Ultimately, the authors concluded that neither established rule is currently recommendable, emphasizing the need for prospective derivation using rigorous methodological standards.

Do not rely on the current literature to adopt a specific chest X-ray decision rule for non-traumatic chest pain. While the Hess rule showed better sensitivity, the meta-analysis found insufficient evidence to recommend either tool at the bedside. Remember that the utility of these rules is hampered by high heterogeneity and retrospective design; therefore, current guidelines should treat imaging as a low-yield diagnostic step.

Civilian penetrating traumatic brain injury in South-East Norway

This review details the management protocols for civilian penetrating traumatic brain injury (pTBI) observed in South-East Norway. While the overall prognosis for survivors is favorable, the authors noted significant gaps in adherence to established institutional guidelines. Specifically, compliance rates for prophylactic antibiotics, antimicrobials, intracranial pressure (ICP) monitoring, and timely surgical revision within 12 hours were lower than anticipated. The core message is that despite the severity of the injury, aggressive management mirroring standard TBI principles, such as early CTA, remains crucial for potential survivors. This points to a systemic need to reinforce adherence to best practices in the acute trauma setting.

For any patient with pTBI who is deemed a potential survivor, maintain an aggressive approach incorporating early CTA and adherence to established TBI protocols. Be mindful that institutional guideline compliance for supportive care elements like prophylactic antibiotics or ICP monitoring may be suboptimal, so proactively ensure these steps are covered. This suggests a need for rigorous point-of-care reinforcement of standard TBI management bundles.

Management of patients with suspected but unidentified poisoning in the emergency department: a joint Royal College of Emergency Medicine and National Poisons Information Service best practice guideline

This new joint guideline from the Royal College of Emergency Medicine and the National Poisons Information Service addresses the notoriously difficult scenario of managing patients with suspected, but not yet identified, poisoning in the ED. Recognizing the complexity, the authors have developed a generalized clinical approach intended to guide initial assessment and help narrow down potential toxic agents. The framework emphasizes a toxidromic approach, meaning the management strategy must consider the potential toxicokinetics of various poisons and how the patient's clinical status might evolve. It is crucial to note that this guidance is designed to support initial management and does not supersede the specific, detailed advice found in resources like TOXBASE or the local poisons centre.

When faced with an undifferentiated poisoned patient, adopt a systematic, toxidromic approach focusing on the patient's evolving clinical picture rather than waiting for a definitive diagnosis. Use this guideline to structure your initial assessment and differential generation. Remember that this is a general framework and must always be supplemented by specific poison protocols and local expertise.

Sequence of advanced airway management and epinephrine administration for paediatric patients with non-shockable out-of-hospital cardiac arrest

This retrospective analysis examined the optimal timing of advanced airway management (AAM) versus epinephrine administration in pediatric patients presenting with non-shockable out-of-hospital cardiac arrest (OHCA). The study utilized data from a large, multicenter Japanese registry spanning 2014 to 2022, comparing outcomes between groups where AAM was performed first versus those where epinephrine was given first. After propensity score matching, the researchers compared survival, neurological outcomes, and return of spontaneous circulation (ROSC) between the two sequencing strategies. The key finding was that the order in which these two interventions were initiated did not show a statistically significant association with improved 1-month survival, favorable neurological status, or ROSC in this cohort of pediatric patients.

For pediatric patients in non-shockable OHCA, the current evidence suggests that the sequence of initiating advanced airway management versus epinephrine administration is unlikely to impact short-term survival or neurological outcomes. This supports a pragmatic approach where the intervention can be initiated based on immediate clinical feasibility and resource availability, rather than adhering to a rigid sequence. Be mindful that this finding is based on a retrospective observational study, so caution is warranted when applying these results universally.

Community emergency medicine: a service review of patients that sustain head injuries in the community--can early intervention by a senior clinical decision maker provide care closer to home?

This review details the operational model of a Physician Response Unit (PRU) that extends senior emergency medicine physician care directly into the community setting, specifically addressing patients with head injuries. The team, consisting of physicians and paramedics, is designed to provide expert decision-making closer to the patient's home, thereby potentially avoiding unnecessary emergency department visits. A key aspect highlighted is the empowerment of these senior physicians to manage complex cases, such as anticoagulated patients with head injuries, within the community, following updated NICE guidelines. The service operates across a large geographic area, managing both self-tasked calls and direct requests from ambulance crews. Overall, the model emphasizes optimizing care delivery by determining which patients require advanced care beyond the scope of paramedics but can safely be managed outside the traditional ED setting.

For managing community head injury patients, consider the feasibility of senior physician input outside the ED, especially for those on anticoagulation. If local resources allow, utilizing a physician-led response team can safely triage patients who need advanced assessment but are stable enough to remain at home. Always verify local guidelines regarding anticoagulated patients, as protocols are evolving to support this level of community management.

Prehospital prediction of clinical course in patients with suspected sepsis: a prospective cohort study

This prospective cohort study explored whether variables assessed by paramedics in the prehospital setting could predict the subsequent clinical course in patients presenting with suspected sepsis. The researchers analyzed prehospital data, including measurements used to calculate qSOFA and NEWS2, against in-hospital outcomes such as SOFA score, development of septic shock, and 30-day mortality. They found that several factors independently predicted specific outcomes, such as oxygen saturation, systolic blood pressure, and qSOFA correlating with sepsis severity, while cyanosis and nursing home residency were linked to mortality. Notably, while qSOFA showed better discriminatory ability for septic shock compared to NEWS2, no single prehospital variable predicted all three measured outcomes simultaneously. The authors caution that while prehospital scoring may have a role, established clinical decision aids should not be used in isolation.

While prehospital scores like qSOFA and NEWS2 show some utility in predicting specific septic outcomes, remember that no single prehospital tool predicts the entire spectrum of severity, shock, and mortality. Use these scores as adjuncts to your clinical judgment, paying attention to specific findings like skin color or GCS, but do not rely on them as standalone decision-making anchors.

EMCrit 424 – 2026 Crashing PE Update

This update synthesizes the latest evidence for managing hemodynamically significant pulmonary embolism, effectively merging the new AHA consensus guidelines with the established EMCrit risk-stratification framework. The core value here is creating a cohesive, actionable algorithm that covers the spectrum of severe PE management, including systemic thrombolysis, mechanical thrombectomy, and the role of ECMO. It’s particularly useful because it translates the sometimes cumbersome alphabetic categorization of the AHA into more practical, bedside language for the emergency setting. The article synthesizes recent randomized data to refine treatment pathways for patients presenting with shock or severe hemodynamic compromise due to PE.

When managing a crashing PE, use this integrated algorithm to guide your decision between thrombolysis, thrombectomy, or ECMO based on the patient's specific hemodynamic profile. Remember that the goal is to reconcile the AHA's broad categories into a clear, sequential approach at the bedside. Be mindful that this synthesis is intended to streamline complex guidelines, but local institutional protocols must always guide final therapy.

Mothership and Drip-and-Ship Strategies in Mechanical Thrombectomy for Acute Ischemic Stroke

This systematic review and meta-analysis tackles the long-standing debate regarding the optimal prehospital management pathway for patients presenting with acute ischemic stroke due to a large vessel occlusion (AIS-LVO). Specifically, it compares the outcomes of the 'mothership' approach—direct transport from the initial site to a comprehensive stroke center—against the 'drip-and-ship' strategy, which involves initial evaluation at a local facility before transfer. The authors synthesized existing data to determine if one pathway confers a superior benefit in terms of clinical outcomes for these critically ill patients. The overall goal is to provide evidence-based guidance to streamline acute stroke care coordination.

For AIS-LVO patients, the evidence synthesis suggests a potential advantage to direct transport to a comprehensive center (mothership) over initial evaluation at a local facility (drip-and-ship). However, the authors note that the data are somewhat mixed, and the practical implementation must account for local resource availability. Remember that the benefit of rapid, direct transfer needs to be weighed against the feasibility and quality of care available en route.

Impact of aspirin use on the modified brain injury guidelines for the management of mild traumatic intracranial hemorrhage

This piece addresses the role of pre-injury aspirin use in the management of isolated mild traumatic intracranial hemorrhage (tICH) within the framework of the modified Brain Injury Guidelines (mBIG1). The core finding is a proposal to expand the current mBIG1 criteria to safely accommodate patients who are on aspirin prior to injury. The authors suggest that these aspirin-using patients might be managed effectively with observation at a lower level of care, potentially negating the need for immediate transfer to a regional trauma center. While the proposal is intriguing for streamlining disposition, the authors themselves caution that robust, prospective studies are required before this change can be definitively implemented in practice.

When risk-stratifying a patient with isolated mild tICH, you can consider the inclusion of pre-injury aspirin use when applying the mBIG1 criteria. However, remember that this is a proposed expansion, and definitive management changes await further prospective data. Proceed with caution, and do not rely on this change for immediate disposition decisions.

A randomised controlled trial of defibrillation with manual pressure augmentation during out-of-hospital cardiac arrest

This randomized controlled trial assessed the utility of adding manual pressure augmentation (MPA) during defibrillation for patients experiencing initially shockable out-of-hospital cardiac arrest (OHCA). The primary finding, despite the intervention significantly lowering transthoracic impedance, was that MPA did not translate into improved survival or any other measured clinical outcomes when compared to standard defibrillation protocols. It is worth noting that this trial was prematurely terminated, which inherently limits the scope of its conclusions. Overall, the data suggest a dissociation between a measurable physiological change, like reduced impedance, and actual improved resuscitation endpoints in this setting.

For initially shockable OHCA patients, the evidence does not support adding manual pressure augmentation to standard defibrillation protocols, as it failed to improve survival. While you might observe a reduction in transthoracic impedance with MPA, this measurable change should not prompt a change in your standard rhythm management algorithm. Proceed with standard ACLS guidelines unless further data emerges.

Impact of Cardiopulmonary Resuscitation Health Care Workers' Physical Health Parameters on Cardiopulmonary Resuscitation Performance Quality in Simulated Manikin-Based Settings-A Systematic Review

This systematic review synthesizes evidence regarding how the physical health and fitness levels of healthcare workers performing CPR actually impact the quality of their resuscitation efforts in simulated manikin models. The authors conclude that the physical capacity of the rescuers is a critical determinant of maintaining high-quality chest compressions. Specifically, sustaining the required depth and frequency of compressions demands a combination of both muscular strength and cardiovascular endurance from the personnel. While this is a simulation-based review, the underlying physiological principles suggest a direct link between rescuer fitness and resuscitation quality. It underscores that CPR performance isn't just about technique, but also about the physical stamina of the provider.

Remember that sustained, high-quality compressions require more than just knowing the algorithm; the rescuer's physical endurance matters significantly. While you can't test fitness in the field, recognizing signs of rescuer fatigue during prolonged resuscitation efforts is key to calling for timely role changes. Don't assume technique alone will sustain optimal performance if the team is physically depleted.

Helicopter Emergency Medical Services attendance is associated with favourable survival outcomes in major trauma: derivation and internal validation of prediction models in a regional trauma system

This retrospective analysis examined the survival benefit associated with Helicopter Emergency Medical Services (HEMS) attendance for major trauma patients within a regional system. Using a large cohort of 3225 patients, the authors assessed survival outcomes using the W-statistic methodology, which compares observed survival to expected survival. They found that overall, HEMS attendance was associated with survival exceeding case-mix adjusted predictions, yielding an adjusted W-statistic of 5.23. Notably, the survival benefit was most pronounced in severely injured patients who fell into the moderate probability of survival band (P s 25–45%). Furthermore, the study highlighted that pre-hospital advanced interventions, specifically those related to the pre-hospital emergency assessment (PHEA), appeared to confer a survival benefit even in patients with a low predicted probability of survival.

The data suggest HEMS attendance provides a measurable survival benefit in major trauma, particularly for those with severe injuries and moderate predicted survival chances. While the overall benefit is clear, remember that the benefit appears strongest in the P s 25–45% group. Clinicians should recognize that advanced pre-hospital care, even in low-probability patients, may still be contributing to better outcomes.

A systematic review of mortality and severe morbidities following newborn chest compressions at birth

This systematic review synthesized data regarding the outcomes, specifically mortality and severe morbidities, following the performance of chest compressions (CC) at birth. The authors concluded that the significant variability observed in the reported outcomes cannot be reliably attributed to simple factors like changes over time or differences across geographic locations. They highlighted that the current literature suffers from substantial heterogeneity across inclusion criteria, which muddies the interpretation of existing data. Furthermore, the review pointed out persistent gaps in the evidence base, particularly concerning the differentiation of deaths due to asphyxia versus other causes, and the need for better stratification based on gestational age, the setting of birth, the level of care provided, and the timing of the CC itself. Ultimately, the authors strongly advocated for prospective studies designed according to the Neonatal Utstein guidelines to enhance the precision and comparability of future evidence.

Given the high variability in reported outcomes, don't rely on single studies to dictate changes in your resuscitation protocol. Focus on adhering to established, standardized resuscitation algorithms rather than trying to pinpoint the 'best' timing or technique based on conflicting literature. Remember that the current evidence base is limited by methodological heterogeneity, so consistent, high-quality resuscitation remains the priority.

Endovascular resuscitation: an expert practice review

This expert practice review provides an overview of endovascular resuscitation (EVR), which encompasses novel therapies designed to bridge critically ill patients in shock or cardiac arrest toward definitive care. The authors synthesize current knowledge across several techniques, acknowledging the growing adoption despite ongoing debates regarding risk, efficacy, and practical implementation. The review structures its discussion around case scenarios, specifically addressing out-of-hospital cardiac arrest and non-compressible hemorrhage. It details the underlying physiology and practical application of three escalating interventions: resuscitative endovascular balloon occlusion of the aorta, selective aortic arch perfusion, and extracorporeal cardiopulmonary resuscitation. Ultimately, the goal is to equip emergency physicians with the necessary understanding to advocate for patients who might benefit from these advanced endovascular strategies.

When considering EVR for shock or cardiac arrest, remember that these techniques are escalating interventions aimed at bridging care, not replacements for definitive management. Focus on mastering the initial vascular access principles, as this is a critical first step regardless of the specific advanced technique chosen. Be mindful that the literature reflects growing adoption alongside persistent controversies regarding risk stratification.

On the optimal sodium correction rate in hyponatraemia and clinical outcome: a meta-analysis

This meta-analysis synthesized data from 11 retrospective studies involving over 27,000 patients to evaluate the impact of different sodium correction rates on mortality and osmotic demyelination syndrome (ODS) in emergency department patients with hyponatremia. The authors specifically tested correction rate thresholds of 8, 10, and 12 mmol/L per 24 hours. Overall, the findings suggest that rapid sodium correction is associated with improved survival, even when comparing across different established thresholds. While the data is compelling regarding survival benefits, the authors caution that no definitive causal link can be established from this observational synthesis. Furthermore, the risk of ODS remains a serious consideration that must guide clinical management.

Given the observed association, a more aggressive approach to sodium correction might improve survival in the acute setting. However, remember that this is observational data, and the risk of ODS is a major contraindication that cannot be ignored. Therefore, while aiming for a faster rate is supported, careful titration remains paramount to avoid precipitating neurological complications.

Robotic surgery in colorectal emergencies: a systematic review of current evidence

This systematic review synthesizes the current evidence regarding the use of robotic platforms for managing acute colorectal emergencies. The authors conclude that while robotic assistance is technically feasible and safe in these emergent settings, its successful implementation is not straightforward. Optimal outcomes appear contingent upon robust institutional infrastructure, including dedicated training programs and the establishment of specialized, multidisciplinary teams. The review suggests that simply having the equipment is insufficient; process standardization and team competency are key determinants of safety and efficacy when performing these procedures outside of elective settings. This provides a good overview of the current landscape for adopting advanced surgical tools in the acute care environment.

When considering robotic assistance for acute colorectal pathology, remember that feasibility and safety are established, but performance hinges on team readiness. Ensure your institution has formalized training pathways and dedicated personnel rather than relying on ad-hoc use. Proceed with caution, recognizing that optimal outcomes require a structured, team-based approach.

New Guidelines Emphasize Outpatient Treatment of Asymptomatic Hypertension

The updated guidelines from ACC/AHA and ACEP are refining the approach to managing asymptomatic hypertension encountered in the emergency department setting. The core message seems to be a stronger emphasis on directing patients with asymptomatic elevations toward appropriate outpatient management rather than immediate ED intervention. These guidelines clarify the criteria for when initiating pharmacotherapy and what level of follow-up is necessary for these patients. This shift suggests a move toward optimizing resource utilization by reserving acute ED resources for symptomatic or severely elevated cases. It's important to review the specific thresholds and follow-up protocols outlined in these new recommendations.

When encountering asymptomatic hypertension in the ED, the focus should be on risk stratification and clear outpatient follow-up planning rather than immediate initiation of therapy. Confirming the patient's baseline status and ensuring they understand the need for follow-up with primary care or cardiology is key. Be mindful that these guidelines are shifting the default management away from acute intervention.

Comparison of three point-of-care ultrasound techniques to confirm endotracheal tube placement: A randomized clinical trial

This randomized clinical trial compared three different point-of-care ultrasound (POCUS) techniques for confirming endotracheal tube (ETT) placement following rapid sequence intubation (RSI). The study found that all three assessed ultrasound methods demonstrated high diagnostic accuracy for confirming the tube's location. Notably, the technique utilizing transcranial ultrasound (TUS) was reported to provide the quickest confirmation time among the methods tested. This suggests that while multiple modalities are effective, the speed of confirmation might be a key operational advantage.

When confirming ETT placement after RSI, remember that all three ultrasound techniques assessed performed well diagnostically. However, if time is a critical factor, TUS appears to offer the shortest confirmation time. Be mindful that this is a comparison of speed and accuracy, and the choice of technique should balance diagnostic certainty with operational efficiency.

Triage administration of sucrose for gastroenteritis in children; a randomized controlled trial

This randomized controlled trial assessed the utility of administering a single dose of sucrose solution to children presenting to the emergency department with gastroenteritis. The primary outcome measured was the improvement in oral rehydration intake following sucrose administration. The authors concluded that giving sucrose alone does not enhance the amount of fluid intake achieved through standard oral rehydration therapy in this acute setting. This finding suggests that while sucrose might be appealing for its perceived energy boost, its routine use in the ED setting for gastroenteritis management is not supported by this evidence.

Do not initiate sucrose supplementation solely for the purpose of boosting oral rehydration intake in pediatric gastroenteritis patients in the ED. Standard, appropriate electrolyte-containing oral rehydration solutions remain the cornerstone of therapy, and adding sucrose does not provide a measurable benefit to fluid intake. Be mindful that this trial specifically addressed the acute ED setting.
