Outcomes of pediatric in-hospital cardiac arrest in the emergency department of a tertiary referral hospital in Tanzania: a retrospective cohort study

BackgroundCardiopulmonary resuscitation (CPR) is an emergency procedure performed to restore heart function to minimize anoxic injury to the brain following cardiac arrest.Despite the establishment of emergency department and training on Pediatric Advanced Life Support (PALS) at Muhimbili National Hospital (MNH) the outcomes of pediatric in-hospital cardiac arrest have not been documented. We ought to determine the outcomes and factors associated with 24-h survival after pediatric in-hospital cardiac arrests at MNH in Tanzania.MethodsWe conducted a retrospective study of all patients aged 1 month to 18 years who had in-hospital cardiac arrests (IHCA) prompting CPR in the Emergency Medicine Department (EMD) at MNH, Tanzania from January 2016 to December 2019. Data was collected from electronic medical record (Wellsoft) system using a standardized and pretested data collection form that recorded clinical baseline, pre-arrest, arrest, and post-arrest parameters. Bivariate and multivariable logistic regression analyses were performed to assess the influence of each factor on 24-h survival.ResultsA total of 11,951 critically ill patients were screened, and 257 (2.1%) had cardiac arrest at EMD. Among 136 patients enrolled, the median age was 1.5 years (interquartile range: 0.5–3 years) years, and the majority 108 (79.4%) aged ≤ 5 years, and 101 (74.3%) had been referred from peripheral hospitals. Overall stained return of spontaneous circulation was achieved in 70 (51.5%) patients, 24-h survival was attained in 43 (31.3%) of patients, and only 7 patients (5.2%) survived to hospital discharge. Factors independently associated with 24-h survival were CPR event during the day/evening (p = 0.033), duration of CPR ≤ 20 min (p = 0.000), reversible causes of cardiac arrest being identified (p = 0.001), and having assisted/mechanical ventilation after CPR (p = 0.002).ConclusionIn our cohort of children with cardiac arrest, survival to hospital discharge was only 5%. Factors associated with 24-h survival were CPR events during the daytime, short duration of CPR, recognition of reversible causes of cardiac arrest, and receiving mechanical ventilation. Future studies should explore the detection of decompensation, the quality of CPR, and post-cardiac arrest care on the outcomes of IHCA.

Prognosis, risk factors, and scoring model of patients resuscitated from traumatic cardiac arrest: A multicenter observational study in Japan.

A subset of patients with traumatic cardiac arrest is salvageable when the reversible causes of cardiac arrest are promptly treated. However, prognosis and risk factors of survivors upon hospital admission after traumatic cardiac arrest remain unclear. We aimed to describe the outcomes, identify risk factors, and develop a simple risk-scoring model for patients resuscitated from traumatic cardiac arrest. This observational multicenter study analyzed data from the Japan Trauma Data Bank from January 1, 2019, to December 31, 2021. Patients who underwent cardiopulmonary resuscitation in the emergency department and survived to the day after hospital admission for traumatic cardiac arrest were included. Factors associated with survival to hospital discharge were determined using mixed-effects multivariable logistic regression analysis. A simple scoring model was developed to stratify the probability of survival to hospital discharge. In total, 452 patients from 119 hospitals (median age, 64 years; 334 [74.4%] men) were included in the analysis. Of these, 130 (28.8%) survived until discharge. Penetrating injury, signs of life upon hospital arrival, and Injury Severity Score were significantly associated with survival at hospital discharge. A scoring model that assigned 1 point each for penetrating injury and signs of life upon hospital arrival effectively stratified the probability of survival to hospital discharge, with scores of 0, 1, and 2 corresponding to survival probabilities of 12.2%, 35.2%, and 83.3%, respectively. This study described the outcomes and risk factors of patients resuscitated from traumatic cardiac arrest. Our simple scoring model effectively stratified the likelihood of survival to hospital discharge. Therapeutic/Care Management; Level III.

What factors are effective on the CPR duration of patients under extracorporeal cardiopulmonary resuscitation: a single-center retrospective study

BackgroundExtracorporeal cardiopulmonary resuscitation (ECPR) is an alternative method for patients with reversible causes of cardiac arrest (CA) after conventional cardiopulmonary resuscitation (CCPR). However, cardiopulmonary resuscitation (CPR) duration during ECPR can vary due to multiple factors. Healthcare providers need to understand these factors to optimize the resuscitation process and improve outcomes. The aim of this study was to examine the different variables impacting the duration of CPR in patients undergoing ECPR.MethodsThis retrospective, single-center, observational study was conducted on adult patients who underwent ECPR due to in-hospital CA (IHCA) or out-of-hospital CA (OHCA) at Hamad General Hospital (HGH), the tertiary governmental hospital of Qatar, between February 2016 and March 2020. Univariate and multivariate binary logistic regression analyses were performed to identify the prognostic factors associated with CPR duration, including demographic and clinical variables, as well as laboratory tests.ResultsThe mean ± standard division age of the 48 participants who underwent ECPR was 41.50 ± 13.15 years, and 75% being male. OHCA and IHCA were reported in 77.1% and 22.9% of the cases, respectively. The multivariate analysis revealed that several factors were significantly associated with an increased CPR duration: higher age (OR: 1.981, 95%CI: 1.021–3.364, P = 0.025), SOFA score (OR: 3.389, 95%CI: 1.289–4.911, P = 0.013), presence of comorbidities (OR: 3.715, 95%CI: 1.907–5.219, P = 0.026), OHCA (OR: 3.715, 95%CI: 1.907–5.219, P = 0.026), and prolonged collapse-to-CPR time (OR: 1.446, 95%CI:1.092–3.014, P = 0.001). Additionally, the study found that the initial shockable rhythm was inversely associated with the duration of CPR (OR: 0.271, 95%CI: 0.161–0.922, P = 0.045). However, no significant associations were found between laboratory tests and CPR duration.ConclusionThese findings suggest that age, SOFA score, comorbidities, OHCA, collapse-to-CPR time, and initial shockable rhythm are important factors influencing the duration of CPR in patients undergoing ECPR. Understanding these factors can help healthcare providers better predict and manage CPR duration, potentially improving patient outcomes. Further research is warranted to validate these findings and explore additional factors that may impact CPR duration in this population.

C76 FINDING OF MYOCARDIAL CRYPTS IN SUDDEN CARDIAC ARREST PATIENTS: TWO CASE REPORT

Abstract Left ventricular myocardial crypts are definined as deep blood–filled invaginations trasversing > 50% of the myocardial wall and are located predominantly at the mid–basal segment of inferoseptal wall or at the apical segment. To date the incidence of crypts is 9.1% of patients undergoing cardiac CT and are not associated with intermediate–term major adverse cardiovascular events. However several studies have suggested that the presence of crypts is a marker of myocardial disease that should warrant clinical follow–up prior to the potential development of left ventricular hypertrophy and occurrence of serious cardiovascular events, such as heart failure or death. A lot of publications demonstrate that ventricular crypts could be a pre–phenotypic marker of hypertrophic cardiomyopathy (HCM). HCM is a genetic ereditary cardiomyopathy which is associated with fatal ventricular arrhytmias. We present the case of two patients who had a sudden cardiac arrest resuscitated with cardiac defibrillation. These are two males, 59 and 53 years old respectively, without cardiovascular risk factor and with familiarity for HCM. The first patient had a sudden cardiac arrest during exercise and was resuscitated with early cardiac defibrillation. The second patient had ventricular fibrillation after otolaryngology surgery treated with single defibrillator shock. Coronary arteries were free from atherosclerotic lesions at the angiografy study and no other reversible causes of cardiac arrest were identified. CMR showed normal biventricular funtion and ruled out signs of myocardial oedema or fibrosis. The only morphological finding was the detection of single left ventricular myocardial crypt at the CMR study in both patients: in one patient the crypt was located at the inferior wall while in the other at the level of the septum in the mid–apical segment. Ultimately both patients underwent genetic testing for cardiomyopathy. These findings may be a pre–phenotypic markers of HCM in patients who don’t present a clear expression of the pathology but may be a correlation with sudden cardiac arrest. The rarity of their finding in patient who have had sudden cardiac arrest can be explained by the small survival rate in patients with sudden cardiac arrest. Future studies and the increasingly simple access to advanced imaging methods like CMR and CT will allow us to clarify the role of these myocardial anomalies in the risk of developing fatal arrhythmic events.

Traumatic Cardiac Arrest in Polytrauma–There are Survivors: A 10-Year Analysis from a German Helicopter Base

Introduction:In Germany, emergency care is provided by ambulances and rescue helicopters. Emergency physicians are part of prehospital care. The rescue helicopter in Dresden covers the city with 540.000 inhabitants and surrounding areas. The goal of the study was to evaluate cases of traumatic cardiac arrest (TCA) and to describe factors that affect the primary success of prehospital cardiopulmonary resuscitation (CPR) in trauma.Method:Data of all emergencies from the German Air Rescue (DRF-Luftrettung®) Helicopter Base Dresden were recorded on a standardized protocol and transferred to a central database (MEDAT®, HEMSDER®). Data from all patients with severe injuries, classified as polytrauma between January 2006 and December 2015 were analyzed.Results:There were a total number of 14,126 emergency cases involving the rescue Helicopter. The Helicopter was on the scene within 10.9 minutes [4-34]. Polytraumatized patients were identified in 673 cases (4.76%), the mean age was 43.73 years [2-98], and 498 patients were male (73.99%). In 444 cases, traffic accidents were responsible, in 188 cases falls from high. In 46 cases a suicide was documented. Mean ISS was 34,04 [16-75]. The main injury regions were head, extremities and chest. In 115 patients (17.08%) a TCA was observed. 43 pat. were pronounced dead initially and no treatment was initiated. 72 pat. (62.6%) received CPR. 39 of these pat. (54,17%) were also pronounced dead after treatment. 14 pat. (19.44%) were transported to hospital with ongoing CPR. 19 pat. (27.38%) reached the return of spontaneous circulation (ROSC). Male pat. reached more often ROSC.Conclusion:According to present guidelines for TCA, it is important that reversible causes of cardiac arrest in trauma pat. are to be treated. If we ensure the treatment of hypoxia, hypovolemia, tension pneumothorax and cardiac tamponade consequently, there will be a survival chance. Regular training for manual skills and simulation can be a key factor.

The effect of interprofessional simulations on pharmacy and physician assistant students' learning of advanced cardiac life support concepts

BackgroundThe Interprofessional Education Collaborative (IPEC) defined core competencies for IPE in 2011, and use of simulation in interprofessional education (IPE) continues to be developed in prelicensure health education programs. Interprofessional education activityIn this prospective, observational study, interprofessional student teams addressed reversible causes of cardiac arrest in weekly simulations during an Emergency Medicine course. Each simulation was followed by sequential team debriefs, first regarding the IPEC core competencies of interprofessional communication, teamwork, and roles and responsibilities, and second regarding the patient-related content of the case. DiscussionTwenty-eight pharmacy students and 60 physician assistant students completed the course. A didactic knowledge exam was administered before, immediately after, and 150 days after the course. Both disciplines' exam scores significantly increased from baseline to the end of the course and from baseline to the 150-day follow-up. Students also completed the validated Interprofessional Perceptions Survey before and after the course. Both disciplines demonstrated significant increases in Team Value, Efficiency and Interprofessional Accommodation components. ImplicationsParticipation in this simulation-based course resulted in 150-day retention of advanced cardiovascular life support knowledge and improved interprofessional perceptions in both pharmacy and physician assistant students.

Cardiopulmonary resuscitation in special circumstances

The standard process of basic and advanced life support can be complicated by a number of special circumstances. Over the last decade, the European Resuscitation Council developed an increasingly detailed guideline regarding the diagnosis and therapy of these situations. In our short review, we summarize the most important recommendations for the management of cardiopulmonary resuscitation in special circumstances. The proper training in non-technical skills and teamwork is crucial in the management of these situations. In addition, extracorporeal circulatory and respiratory support play an increasingly important role in some special circumstances with appropriate patient selection and timing. We also summarize the therapeutic options regarding the reversible causes of cardiac arrest as well as the steps of diagnostic and treatment methods in some special situations (cardiopulmonary resuscitation in the operating room, after cardiac surgery, in a catheterisation laboratory, after sudden cardiac arrest at dentistry or dialysis station) and among special patient populations (patient with asthma or COPD, neurologic disorders, obese patient, pregnant woman). Orv Hetil. 2023; 164(13): 488-498.

Advanced and Invasive Cardiopulmonary Resuscitation (CPR) Techniques as an Adjunct to Advanced Cardiac Life Support.

Despite numerous promising innovations, the chance of survival from sudden cardiac arrest has remained virtually unchanged for decades. Recently, technological advances have been made, user-friendly portable devices have been developed, and advanced invasive procedures have been described that could improve this unsatisfactory situation. A selective literature search in the core databases with a focus on randomized controlled trials and guidelines. Technical aids, such as feedback systems or automated mechanical cardiopulmonary resuscitation (CPR) devices, can improve chest compression quality. The latter, as well as extracorporeal CPR, might serve as a bridge to treatment (with extracorporeal CPR even as a bridge to recovery). Sonography may be used to improve thoracic compressions on the one hand and to rule out potentially reversible causes of cardiac arrest on the other. Resuscitative endovascular balloon occlusion of the aorta might enhance myocardial and cerebral perfusion. Minithoracostomy, pericardiocentesis, or clamshell thoracotomy might resolve reversible causes of cardiac arrest. It is crucial to identify those patients who may benefit from an advanced or invasive procedure and make the decision to implement the intervention in a timely manner. As with all infrequently performed procedures, sound education and regular training are paramount.

Extracorporeal resuscitation-criteria, prerequisites, outcome : A reality check

Für ausgewählte Patienten, in denen die konventionelle kardiopulmonale Reanimation (cCPR) erfolglos bleibt, sprechen die europäischen Leitlinien zur Reanimation 2021 erstmals eine Empfehlung zur extrakorporalen Reanimation (eCPR) als mögliche Rettungstherapie aus. Die eCPR wird im therapierefraktären Kreislaufstillstand etabliert, um Diagnostik und Therapie reversibler Ursachen, wie Herzinfarkt, Lungenembolie, akzidentielle Hypothermie, Intoxikationen mit herzwirksamen Substanzen und akute Hypoxie, zu ermöglichen. Selektionskriterien für eCPR umfassen prognostische Reanimationsfaktoren, wie beobachteter Kreislaufstillstand, Start von Reanimationsmaßnahmen in < 5 min, schockbarer Erstrhythmus, Zeichen effektiver cCPR wie Lebenszeichen während der Reanimation, anhaltendes Kammerflimmern, intermittierende Phasen von Spontankreislauf oder anhaltendes endtidales CO2 > 10 mm Hg, Patientenalter und Gesundheitszustand. Die Zeitspanne vom Kreislaufstillstand bis zur eCPR ist eine der wichtigsten Determinanten für neurologisch gutes Überleben und sollte < 60 min liegen. Für die Einhaltung dieser Zielvorgabe muss eine entschlossene „Load-and-Go“-Strategie mit frühzeitiger Patientenselektion und raschem Transport unter mechanischer cCPR in ein eCPR-Zentrum verfolgt werden, oder es wird versucht, die eCPR präklinisch zum Einsatz zu bringen. Zwei randomisierte kontrollierte eCPR-Studien demonstrierten Überlebensraten von 43 % bzw. 31,5 % bei Patienten mit anhaltendem Kammerflimmern bzw. kardialem Kreislaufstillstand. Ob diese Ergebnisse außerhalb einzelner hochspezialisierter Zentren anwendbar sind, ist wie die Frage nach der besten präklinischen und innerklinischen Strategie Gegenstand zukünftiger Studien.

Impact of Specific Emergency Measures on Survival in Out-of-Hospital Traumatic Cardiac Arrest

The management of out-of-hospital traumatic cardiac arrest (TCA) for professional rescuers entails Advanced Life Support (ALS) with specific actions to treat the potential reversible causes of the arrest: hypovolemia, hypoxemia, tension pneumothorax (TPx), and tamponade. The aim of this study was to assess the impact of specific rescue measures on short-term outcomes in the context of resuscitating patients with a TCA. This retrospective study concerns all TCA patients treated in two emergency medical units, which are part of the Northern French Alps Emergency Network (RENAU), from January 2004 through December 2017. Utstein variables and specific rescue measures in TCA were compiled: fluid expansion, pelvic stabilization, tourniquet application, bilateral thoracostomy, and thoracotomy procedures. The primary endpoint was survival rate at Day 30 with good neurological status (Cerebral Performance Category [CPC] score CPC 1 and CPC 2). In total, 287 resuscitation attempts in TCA were included and 279 specific interventions were identified: 262 fluid expansions, 41 pelvic stabilizations, five tourniquets, and 175 bilateral thoracostomies (including 44 with TPx). Among the standard resuscitation measures to treat the reversible causes of cardiac arrest, this study found that bilateral thoracostomy and tourniquet application on a limb hemorrhage improve survival in TCA. A larger sample for pelvic stabilization is needed.

In-hospital cardiac arrest due to pulmonary embolism – Treatment and outcomes in a Swedish cohort study

ObjectivesPulmonary embolism (PE) constitutes one of the reversible causes of cardiac arrest. The prognosis for PE-related cardiac arrest is poor. Some previous studies have suggested a higher survival rate in patients with PE-related cardiac arrest who receive thrombolysis. No such study has focused on in-hospital cardiac arrests (IHCA). AimTo describe the prevalence of PE-related IHCA and the characteristics of those patients, as well as to describe favourable and adverse outcomes after thrombolysis. Material and methodsAll patients ≥ 18 years who experienced an IHCA at Karolinska University Hospital between 2007 and 2020 with PE as the primary cause of IHCA were included. Patients were identified from the Swedish Registry for Cardiopulmonary Resuscitation (SRCR). Data was collected from the SRCR and medical records. The primary outcome was survival to discharge. Secondary outcomes were alive at the end of CPR, major bleeding, and minor bleeding. ResultsOut of 2,128 IHCA patients, 64 (3%) had a PE-related IHCA of whom 16 (25%) had thrombolysis. A significant association was seen between thrombolysis and survival to discharge (44 % vs 8 %, p-value < 0.01). Major bleeding was not seen in any patient. ConclusionPulmonary embolism is an uncommon cause of IHCA, and thrombolysis is often not administered in such patients. Thrombolysis may increase survival to hospital discharge, and among the selected patients treated with thrombolysis in our study, there was no apparent major bleeding.

Cardiac arrest in special circumstances.

European Resuscitation Council Guidelines for Cardiopulmonary Resuscitation prioritize treatments like chest compression and defibrillation, known to be highly effective for cardiac arrest from cardiac origin. This review highlights the need to modify this approach in special circumstances. Potentially reversible causes of cardiac arrest are clustered into four Hs and four Ts (Hypoxia, Hypovolaemia, Hyperkalaemia/other electrolyte disorders, Hypothermia, Thrombosis, Tamponade, Tension pneumothorax, Toxic agents). Point-of-care ultrasound has its role in identification of the cause and targeting treatment. Time-critical interventions may even prevent cardiac arrest if applied early. The extracorporeal CPR (eCPR) or mechanical CPR should be considered for bridging the period needed to reverse the precipitating cause(s). There is low quality of evidence available to guide the treatment in the majority of situations. Some topics (pulmonary embolism, eCPR, drowning, pregnancy and opioid toxicity) were included in recent ILCOR reviews and evidence updates but majority of recommendations is based on individual systematic reviews, scoping reviews, evidence updates and expert consensus. Cardiac arrests from reversible causes happen with lower incidence. Return of spontaneous circulation and neurologically intact survival can hardly be achieved without a modified approach focusing on immediate treatment of the underlying cause(s) of cardiac arrest.

Singapore Advanced Cardiac Life Support Guidelines 2021.

Advanced cardiac life support (ACLS) emphasises the use of advanced airway management and ventilation, circulatory support and the appropriate use of drugs in resuscitation, as well as the identification of reversible causes of cardiac arrest. Extracorporeal cardiopulmonary resuscitation and organ donation, as well as special circumstances including drowning, pulmonary embolism and pregnancy are addressed. Resuscitation does not end with ACLS but must continue in post-resuscitation care. ACLS also covers the recognition and management of unstable pre-arrest tachy- and bradydysrhythmias that may deteriorate further.

Point-of-care testing in out-of-hospital cardiac arrest: a retrospective analysis of relevance and consequences

BackgroundMetabolic and electrolyte imbalances are some of the reversible causes of cardiac arrest and can be diagnosed even in the pre-hospital setting with a mobile analyser for point-of-care testing (POCT).MethodsWe conducted a retrospective observational study, which included analysing all pre-hospital resuscitations in the study region between October 2015 and December 2016. A mobile POCT analyser (Alere epoc®) was available at the scene of each resuscitation. We analysed the frequency of use of POCT, the incidence of pathological findings, the specific interventions based on POCT as well as every patient’s eventual outcome.ResultsN = 263 pre-hospital resuscitations were included and in n = 98 of them, the POCT analyser was used. Of these measurements, 64% were performed using venous blood and 36% using arterial blood. The results of POCT showed that 63% of tested patients had severe metabolic acidosis (pH < 7.2 + BE < − 5 mmol/l). Of these patients, 82% received buffering treatment with sodium bicarbonate. Potassium levels were markedly divergent normal (> 6.0 mmol/l/ < 2.5 mmol/l) in 17% of tested patients and 14% of them received a potassium infusion. On average, the pre-hospital treatment time between arrival of the first emergency medical responders and the beginning of transport was 54 (± 20) min without POCT and 60 (± 17) min with POCT (p = 0.07). Overall, 21% of patients survived to hospital discharge (POCT 30% vs no POCT 16%, p = 0.01, Φ = 0.16).ConclusionsUsing a POCT analyser in pre-hospital resuscitation allows rapid detection of pathological acid–base imbalances and potassium concentrations and often leads to specific interventions on scene and could improve the probability of survival.

The Role of Cardiac Arrest Sonographic Exam (CASE) in Predicting the Outcome of Cardiopulmonary Resuscitation; a Cross-sectional Study.

Introduction:Ultrasonography (US) has been suggested as an integral part of resuscitation to identify potentially reversible causes of cardiac arrest (CA). This study aimed to evaluate the association between cardiac activity on ultrasonography during resuscitation and outcome of patients with non-shockable rhythms.Methods:We conducted a prospective, observational study on adult patients presenting with CA or experiencing CA in the emergency department (ED), and initial non-shockable rhythm. US examination of the sub-xiphoid region was performed during the 10-second interval of rhythm and pulse check and the association of US findings and patients’ outcomes was evaluated. Results: 151 patients with the mean age of 65.32 ± 11.68 years were evaluated (76.2% male). 43 patients (28.5%) demonstrated cardiac activity on the initial US. The rate of asystole in initial rhythm was 58.9% (n=89). Return of spontaneous circulation (ROSC) was achieved in 36 (23.8%) patients, twenty (13.2%) survived to hospital admission and seven (4.6%) survived to hospital discharge. When the cardiac standstill duration increased to six minutes, no patient survived hospital discharge. Potentially reversible causes were detected in 15 cases (9.9%), and four of them survived to hospital discharge. Cardiac activity on first scan was associated with ROSC (OR: 6.86, 95%CI: 2.92-16.09; p < 0.001), survival to hospital admission (OR: 17.80, 95%CI: 3.95–80.17; p < 0.001), and survival to hospital discharge (OR: 17.35, 95%CI: 2.02–148.92; p = 0.001).Conclusion: In non-traumatic cardiac arrest patients with non-shockable rhythms, bedside US is of great importance in predicting ROSC. The presence of pulseless electrical activity (PEA) rhythm and cardiac activity on initial US were associated with ROSC, survival to hospital admission, and hospital discharge. When the cardiac standstill duration increased to six minutes, no patient survived hospital discharge.

Upotreba ultrazvuka u kardiopulmonalnoj reanimaciji - ultrazvuk u KPR

Ultrasound has predictive value of identification and management of reversible causes of cardiac arrest on the outcome after applied CPR, in terms of ROSC (return of spontaneous circulation) and the hospital discharge and neurological findings after applied CPR measures. Ultrasound is used in all phases of resuscitation including period before cardiac arrest, during cardiopulmonary resuscitation (CPR), and in the period after that. Ultrasound use during CPR offers numerous advantages including non-invasiveness, easiness, the short time for examination and a safe possibility for a repeat test whenever it is needed. Focused Echocardiography Examination in Life support (FEEL) and Focused Echocardiographic Evaluation in Resuscitation (FEER) protocols are mostly used when we talk about heart examination in cardiopulmonary resuscitation.

Echographie pulmonaire en réanimation pédiatrique : revue des connaissances en 2020

L’échographie pulmonaire (EP) s’est considérablement répandue en réanimation adulte mais son utilisation néonatale et pédiatrique, bien que croissante, reste plus limitée et la radiographie thoracique demeure l’examen de première ligne dans la plupart des centres. L’objectif de cette revue est de faire le point sur les études menées spécifiquement en réanimation pédiatrique, afin de présenter les connaissances déjà établies, les avantages et les limites de l’EP. Après un point sur son utilisation dans les pathologies néonatales et communautaires pédiatriques, nous abordons les utilisations spécifiques à la réanimation de l’enfant. L’EP présente un triple intérêt de diagnostic d’urgence, de guide aux procédures thérapeutiques et de suivi évolutif en temps réel ou différé. En néonatologie, elle aide à identifier l’étiologie des détresses respiratoires immédiates et secondaires et la gestion des détresses vitales. En pédiatrie communautaire, elle est utile au diagnostic de pneumonie et de bronchiolite et à la détection de complications. En réanimation pédiatrique, elle permet la mise en évidence des pneumopathies acquises sous ventilation mécanique (PAVM) et l’évaluation et le suivi du recrutement alvéolaire notamment dans le syndrome de détresse respiratoire aigüe (SDRA) ou les atélectasies péri opératoires. En combinaison avec le monitorage hémodynamique, elle aide à la surveillance des patients à risque d’oedème pulmonaire notamment dans les cardiopathies ou les sepsis. Enfin elle détecte rapidement les complications pulmonaires de réanimation ou post-opératoires, les atteintes thoraciques traumatiques et certaines causes potentiellement réversibles d’arrêt cardiaque. La publication récente des recommandations internationales pédiatriques et néonatales sur l’échographie d’urgence pourrait encourager sa diffusion dans la pratique courante.

Reversible causes of cardiac arrest: Nursing competency acquisition and clinical simulation satisfaction in undergraduate nursing students

BackgroundIt is essential to determine and treat the reversible causes of cardiac arrest, so emergency nurses must acquire the competencies needed for its adequate management. Method106 undergraduate nursing students participated in a cross-sectional study, using a mixed-method. Simulated scenarios recreated critically ill patients with diagnoses of potentially reversible causes of cardiac arrest in an emergency room. An internally validated questionnaire was used to analyse students’ satisfaction and perceptions about clinical simulation sessions. Nursing competencies were assessed using a verification list. Data were analysed using the IBM SPSS Statistics version 24.0 (quantitative data) and ATLAS-ti version 8.0 (qualitative data) software. ResultsNursing students expressed a high level of satisfaction (most of the scores obtained were higher than 90%) and positive perceptions about clinical simulation sessions. Most of the students (85.6%) acquired the necessary nursing competencies for adequate management of the reversible causes of cardiac arrest. ConclusionClinical simulation methodology is a useful tool for the learning process and acquisition of nursing competencies related to emergency situations management. This methodology prepares nursing students for their clinical placements and future careers in emergency care. Therefore, it is recommended to extend clinical simulation training to emergency qualified nursing staff and advanced practitioners.
