Background: Simulation-based training courses have been developed and widely accepted.The use of simulators can prevent bitter consequences that may sometimes put human lives in danger. Increasing the skill of nursing students in dealing with trauma patients is of great importance. The aim of this study is to evaluate the effectiveness of the simulation-based trauma training program for the management of trauma patients in nursing students.

Method: It is an observational approach that focuses on improving the learning of trauma care skills. For this study, 6th and 8th semester nursing students were selected by appropriate sampling method. Previously, these students completed the trauma training course without simulation. Training of trauma skills was done using multi-purpose trauma mollage And we subsequently analyzed the effectiveness of the trauma simulation training program using the OSCE test. In the inferential statistics section, after examining the data distribution (Kolmogrove-Smirnov and Shapiro-Wilk tests), the Wilcoxon test was used to measure significance. SPSS 22 software was used.

Results: The results indicated that the lowest mean score obtained based on a scale of zero to one hundred was for the movement limitation of the injured long bone and the highest was in the skill of oral-nasal intubation and ventilation. The results of the paired t-test showed that clinical skills for dealing with trauma-affected individuals in undergraduate nursingafter simulation training was significantly higher .

Conclusion: The implementation of the simulation is accompanied by an increase in the skills of the participants, which leads to the application of the acquired knowledge in real-life scenarios and positive changes. In the learning of the participants, the evaluation of conventional trauma training in Iran, like other countries, shows the need for specialized training through simulation. To ensure the continued effectiveness of simulation-based trauma training courses, it is recommended that administrators and policymakers encourage regular faculty participation in the program. Long term effects of trauma simulators training in nursing student requires further study.

Background: Cervical epidural hematoma (CEH) is a rare but potentially devastating condition, characterized by the accumulation of blood within the epidural space of the cervical spine, leading to spinal cord compression (Perron AD, Huff JS. Spinal cord disorders. In: Marx JA, et al. editors. Rosen's emergency medicine: concepts and clinical practice. 8th ed. Philadelphia: Saunders; 2013. pp. 1419-27.); (Raasck K, Habis AA, Aoude A, Simoes L, Barros F, Reindl R. Spontaneous spinal epidural hematoma management: a case series and literature review. Spinal Cord Ser Cases. 2017;3:16043. https://doi.org/10.1038/scsandc.2016.43 .); (Ryo Yamamoto M, Ito H, Shimuzu K, Wakabayashi H, Oyama. Two cases of cervical epidural hematoma presenting with left-sided hemiplegia and requiring surgical drainage. Cureus. 2022;14(4):e23915. https://doi.org/10.7759/cureus.23915 .). While trauma and iatrogenic causes are well-documented, cases attributed to neck strain and acupuncture are uncommon. (Raasck K, Habis AA, Aoude A, Simoes L, Barros F, Reindl R. Spontaneous spinal epidural hematoma management: a case series and literature review. Spinal Cord Ser Cases. 2017;3:16043. https://doi.org/10.1038/scsandc.2016.43 .); (Shiraishi S, Goto I, Kuroiwa Y, Nishio S, Kinoshita K. Spinal cord injury as a complication of an acupuncture. Neurology. 1979;29(8):1188-90. https://doi.org/10.1212/wnl.29.8.1188 .) Here, we present two cases of CEH secondary to these unusual aetiologies. Both cases highlight the importance of considering uncommon causes of CEH to ensure early recognition and prompt treatment.

Case presentations: Case 1 is an 81-year-old lady who presented with left hemiparesis and paraesthesia following a fall with neck strain. Magnetic resonance imaging (MRI) of cervical spine revealed left C3-C7 epidural haematoma with severe cord compression. In Case 2, a 35-year-old gentleman experienced sudden onset numbness and weakness in all limbs just 10 minutes after receiving acupuncture. MRI showed an epidural hematoma at the C2-C4 levels. Both patients underwent immediate surgical decompression and had significant recovery.

Conclusion: Although CEH is a rare occurrence, it can potentially be a neurosurgical emergency. Physicians must remain cognizant of the diverse aetiologies associated with CEH and the necessity for early recognition and immediate treatment.

Background: Aortoesophageal fistula (AEF) is a rare cause of upper gastrointestinal hemorrhage. Despite diagnostic and therapeutic advances, the mortality rate in AEF patients remains high because of its fulminant course, even with maximal intensive care. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a resuscitation technique to control life-threatening bleeding. It has become an important modality in the management of life-threatening, traumatic or non-traumatic, arterial bleeding. However, it's use in hemorrhagic shock caused by cancer has rarely been reported.

Case presentation: A 51-year-old woman with a history of esophageal cancer presented to our emergency department with hematemesis. Computed tomography was performed because of a strong suspicion of hemorrhagic shock. With a diagnosis of AEF due to esophageal cancer, emergency thoracic endovascular aortic repair was performed while the bleeding was controlled using REBOA. Staged elective esophageal reconstruction was successfully performed.

Conclusions: Hemostasis is crucial in patients who present with suspected hemorrhagic shock attributable to AEF. The timely implementation of REBOA has shown promise and potential effectiveness in such cases.

Introduction: Entrustable professional activities (EPAs) are one way to assess competencies, and are designed to bridge the gap between theoretical competencies and real world clinical practice.

Aims: This was a systematic review which aims to answer the question: "Which EPAs related to Emergency Medicine are described for medical schools?".

Methods: We included original qualitative, interventional and observational studies (cross-sectional, case-control, and cohort studies) that described EPAs relevant to Emergency Medicine for Medical School. The search strategy was created using a combination of keywords and standardized index terms related to EPAs and Emergency Medicine.

Results: The search strategy identified 991 citations. After screening the titles and abstracts, we identified 85 potentially relevant studies. After the full-text review, a total of 11 reports met the criteria for inclusion.

Conclusion: Recognizing a patient requiring urgent or emergent care and initiating evaluation and management is the most common EPA related to Emergency Medicine described at Medical Schools. Use of EPAs is associated with increased student satisfaction and improved competences. However, there is a lack of undergraduate EM specific EPAs being systematically developed and published, and this should be an area to be explored in future studies.

Background: Russo-Ukrainian war is associated with severe traumas, including injuries to the major vessels. Penetrating aortic injury remains one of the most difficult injuries; the mortality rate is 90-100% in case of gunshot wounds, associated with frequent lethal outcomes due to uncontrolled bleeding. Of the three main abdominal veins, the inferior vena cava (IVC) is the most frequently damaged, which is required quick and appropriate surgical decisions to be made. Little is known about the management of gunshot injuries to such major vessels as the aorta and IVC. It is also worth mentioning about the importance to share our practical experience from the ongoing war for better understanding and future considerations by war surgeons of the vascular trauma management. The aim of the study was to demonstrate the specific features of the diagnosis and management of a gunshot shrapnel blind penetrating wound to the abdomen with injury to the aortic bifurcation level and the infrarenal section of the inferior vena cava.

Case presentation: A 44-year-old male soldier of the Armed Forces of Ukraine received a gunshot injury to the abdomen from a mortars' explosive shelling. The patient was evacuated to the Forward Surgical Team (Role 1) and received primary surgical treatment within one hour after the injury according to the "golden hour" principle. Then, evacuated was performed to the Role 3 hospital in Kharkiv. At the Role 3 hospital, the patient underwent second-look surgery as well as damage control surgery. At revision, no active bleeding was observed, and the surgical pads (packed previously by the Forward Surgical Team) were removed. Further revision showed a metal projectile within the aortic wall at the level of aortic bifurcation and wall defects were also detected for inferior vena cava. This metal projectile was removed by using the multifunctional surgical magnetic tool followed by suturing of the aortic wall defect as well as defects of the inferior vena cava.

Conclusions: Application of Damage Control Surgery is a useful approach in the management of severe vascular injury as well as useful to stop abdominal contamination by intestinal contents. The application of a surgical magnetic tool for the searching and removal of ferromagnetic foreign bodies reduces operative trauma and reduces the time for identification of foreign bodies.

Background: Haemoglobin variation (ΔHb) induced by fluid transfer through the intestitium has been proposed as a useful tool for detecting hydrostatic pulmonary oedema (HPO). However, its use in the emergency department (ED) setting still needs to be determined.

Methods: In this observational retrospective monocentric study, ED patients admitted for acute dyspnoea were enrolled. Hb values were recorded both at ED presentation (T₀) and after 4 to 8 h (T₁). ΔHb between T₁ and T₀ (ΔHb_T1-T0) was calculated as absolute and relative value. Two investigators, unaware of Hb values, defined the cause of dyspnoea as HPO and non-HPO. ΔHb_T1-T0 ability to detect HPO was evaluated. A machine learning approach was used to develop a predictive tool for HPO, by considering the ability of ΔHb as covariate, together with baseline patient characteristics.

Results: Seven-hundred-and-six dyspnoeic patients (203 HPO and 503 non-HPO) were enrolled over 19 months. Hb levels were significantly different between HPO and non-HPO patients both at T₀ and T₁ (p < 0.001). ΔHb_T1-T0 were more pronounced in HPO than non-HPO patients, both as relative (-8.2 [-11.2 to -5.6] vs. 0.6 [-2.1 to 3.3] %) and absolute (-1.0 [-1.4 to -0.8] vs. 0.1 [-0.3 to 0.4] g/dL) values (p < 0.001). A relative ΔHb_T1-T0 of -5% detected HPO with an area under the receiver operating characteristic curve (AUROC) of 0.901 [0.896-0.906]. Among the considered models, Gradient Boosting Machine showed excellent predictive ability in identifying HPO patients and was used to create a web-based application. ΔHb_T1-T0 was confirmed as the most important covariate for HPO prediction.

Conclusions: ΔHb_T1-T0 in patients admitted for acute dyspnoea reliably identifies HPO in the ED setting. The machine learning predictive tool may represent a performing and clinically handy tool for confirming HPO.

Introduction: Myocardial ischemia can occur due to several causes, which result in an imbalance between the supply and demand of oxygen to cardiac muscles. One potential reason for this condition is the overwork of the heart due to hyperstimulated thyroid function.

Case presentation: The patient was a 36-year-old woman who presented with left-sided chest pain, dyspnea, palpitation, and tremor. The initial evaluation showed evidence of myocardial ischemia (positive high-sensitivity troponin) caused by a hyperactive thyroid gland. The treatment for myocardial infarction, along with anti-thyroid medications, improved the patient's condition and subsided the symptoms. The coronary angiography revealed no pathologic finding, and the hypokinetic left ventricle, observed in the first echocardiogram, was resolved. The patient was discharged with an excellent clinical condition, and after the 4-month taking of a calcium channel blocker and tapering carbimazole, the thyroid function became normal, and her symptoms resolved completely.

Conclusion: Patients without evident risk factors for ischemic heart disease, such as non-diabetic, nonsmoker, and young individuals who presented with acute coronary syndrome, should be evaluated for a potential background reason for the imbalance between the oxygen demand and supply of the myocardium. The presence of palpitation, weight loss, tremors, insomnia, and anxiousness, along with ischemic signs, should make the physician think about the probability of the hyperthyroid-induced cardiovascular disorder.

Clinical key point: The initial presentation of hyperthyroidism might be accompanied by severe cardiac symptoms. When the demographic features are not aligned with usual ischemic heart disease, other probable symptoms and signs should be investigated, and thyroid function should be checked. The control of thyroid hyperactivity would result in the resolution of both cardiac and non-cardiac symptoms.

Background: Delivering emergency care in rural areas can be challenging, but video consultation (VC) offers opportunities to make healthcare more accessible. The communication and relationship between professionals and patients have a significant impact on the patient's experience of safety and inclusion. Understanding the patient perspective is crucial to developing good quality healthcare, but little is known about patient experiences of emergency care via VC in a rural context. The aim of this study was to explore patient experiences of emergency care via VC in northern rural Sweden.

Methods: Using a qualitative approach, semi- structured interviews (n = 12) were conducted with individuals aged 18-89 who had received emergency care with a registered nurse (RN) on site and VC with a general practitioner (GP). The interviews were conducted between October 2021 and March 2023 at community hospitals (n = 7) in Västerbotten County, Sweden. Interviews were analysed with content analysis.

Results: The analysis resulted in main categories (n = 2), categories (n = 5) and subcategories (n = 20). In the main category, "We were a team of three", patients described a sense of inclusion and ability to contribute. The patients perceived the interaction between the GP and RN to function well despite being geographically dispersed. Patients highly valued the opportunity to speak directly to the GP. In the main category, "VC was a two-sided coin", some experienced the emergency care through VC to be effective and smooth, while some felt that they received a lower quality of care and preferred face-to-face consultation with the GP. The quality of the VC was highly dependent on the RN's ability to function as the hub in the emergency room.

Conclusion: Patients in rural areas perceived being included in 'the team' during VC, however they experienced disadvantages with the system on individual basis. The nursing profession plays an important role, and a proper educational background is crucial to support RNs in their role as the hub of the visit. The GP's presence via VC was seen as important, but to fully enable them to fulfil their commitments as medical professionals, VC needs to be further improved with education and support from technical devices.

Background: Bleeding in early pregnancy is a common emergency department (ED) presentation. Although variability in approaches has been demonstrated, research is relatively uncommon on practices and outcomes. This study investigated the influence of clinical pattern of care, utility, and contribution of pelvic examination aimed at diagnosing and managing bleeding in early pregnancy at three Canadian EDs.

Methods: After obtaining informed consent, data were collected from adult women who were pregnant and from treating ED physicians using a structured questionnaire. We defined the change in management based on the initial clinical plan at the time of the initial physician assessment in the ED and any subsequent changes made after the pelvic examination was performed. Patient telephone follow-up was supplemented by linking with provincial administrative data for births. Univariable and multivariable binary logistic regression analyses were performed to identify factors associated with a change in patient management following pelvic examination in the ED.

Results: Overall, 200 women were enrolled. The mean age was 31 years, patients had been bleeding for a median of 1 day and stayed in the ED for a median of 5 h. Of these, 166 (83.0%) received a pelvic examination, including speculum examination and/or bimanual palpation. Pregnancy outcome data were available for 192 pregnancies; 107 (56%) experienced a miscarriage. Factors significantly associated with a change in management after pelvic examination in the univariate logistic regression analysis were brown/dark-red bleeding per vaginam (physician determined), tachycardia, right lower quadrant tenderness, and bimanual palpation. In the multivariate logistic regression analysis, brown/dark-red bleeding per vaginam was independently associated with a reduced likelihood of a change in management after pelvic examination (aOR = 0.37; 95% CI: 0.14-0.98).

Conclusion: Among women presenting to the ED with bleeding in early pregnancy prior to 20 weeks gestation, only brown/dark-red vaginal bleeding, potentially indicative of bleeding resolution, significantly independently influenced the baseline odds of a change in management after pelvic examination. Until the debate on the utility of pelvic examination in the ED for this presentation is resolved, physician preferences and shared decision making with patients should guide practice regarding speculum examination/bimanual palpation for the management of bleeding in early pregnancy.

Background: In 2019, there was widespread presentation of respiratory distress as well as other organ system involvement in patients with a history of vaping. There continue to be reports of vaping-associated illness (VAI). This has come to be known as e-cigarette and vaping product associated lung injury (EVALI). The mechanism of injury remains unclear.

Objectives: This study reexamines the clinical characteristics of patients affected by vaping and suggests that lung injury may not be the primary organ dysfunction but be part of a larger systemic illness.

Methods: This is a retrospective chart review of all patients presenting to one hospital identified as having vaping-associated illness RESULTS: Fourteen patients were identified ranging in age from 15 to 33 years. Patients had a broad range of clinical severity. Respiratory symptoms occurred in 64%, gastrointestinal symptoms in 57%, fever in 78%, neurological symptoms in 15% and other constitutional symptoms in 50%. 35% presented with no respiratory symptoms.

Conclusion: While the lungs are certainly involved in vaping-associated illness, recognizing the extent of involvement of other organ systems may provide insight into the pathophysiology of the disease. Providers should be aware that vaping-associated illness presents with a multitude of symptoms outside of lung injury, such as abdominal pain, headache or even fever.
