    查看更多>>摘要:? 2021 Elsevier Inc.Background: Many clinicians are wary of administering 30 cc/kg of intravenous fluid (IVF) to septic patients with reduced left-ventricular ejection fraction (rLVEF), fearing volume overload. Prior studies have used history of heart failure, rather than LVEF measured at presentation, thereby potentially distorting the relationship between rLVEF, IVF, and adverse outcomes. Our goal was to assess the relationship between IVF volume and outcomes in patients with, versus without, rLVEF. Methods: This was a prospective observational study performed at an urban Emergency Department (ED). Included patients were adults with suspected sepsis, defined as being treated for infection plus either systolic blood pressure <90 mm/Hg or lactate >2 mmol/L. All patients had LVEF assessed by ED echocardiogram, prior to receipt of >1 l IVF. Measurements and main results: We enrolled 73 patients, of whom 33 had rLVEF, defined as <40%. Patients with rLVEF were older, had greater initial lactate, more ICU admission, and more vasopressor use. IVF volume was similar between LVEF groups at 3-h (2.2 (IQR 0.8) vs 2.0 (IQR 2.4) liters) while patients with rLVEF were more likely to achieve 30 cc/kg (61% (CI 44–75) vs 45% (CI 31–60). In the reduced versus not-reduced LVEF groups, hospital days, ICU days, and ventilator days were similar: 8 (IQR 7) vs 6.5 (8.5) days, 7 (IQR 7) vs 5 (4) days, and 4 (IQR 8) vs. 5 (10) days, respectively. Conclusions: Septic patients with rLVEF at presentation received similar volume of IVF as those without rLVEF, without an increase in adverse outcomes attributable to volume overload. While validation is needed, our results suggest that limiting IVF administration in the setting of rLVEF is not necessary.

    查看更多>>摘要:? 2021 Elsevier Inc.Background: Direct oral anticoagulant (DOAC) use presents a challenge to all providers involved in emergency care of patients since widely accepted laboratory tests to assess the level of anticoagulation for such medications are lacking. Viscoelastic tests such as thromboelastography (TEG) tests are increasingly used throughout major trauma centers to help guide resuscitation efforts in patients presenting with trauma and/or hemorrhagic shock. Objective: The primary outcome compared TEG parameters between emergency department trauma patients reporting DOAC therapy and known normal TEG parameter values. The secondary outcome evaluated patients who reported time of last known DOAC dose within a preferred time frame of <12 h for once daily dosing DOAC therapy or < 6 h for twice daily dosing DOAC therapy. Methods: This single-center, retrospective cohort study assessed TEG values in patients receiving DOAC therapy and compared these to institution TEG ranges considered normal. TEG values of reaction time (R time), kinetics (K), alpha angle (AA), maximum amplitude (MA), and percent lysis in 30 min (LY30) were collected for patients reporting DOAC therapy. Results: 40 patients were included in this study. 19 patients reported apixaban therapy and 21 reported rivaroxaban therapy. 5 (12.5%) patients had an elevated R time and 1 (2.5%) patient had a reduced MA. All other TEG values did not suggest hypocoagulability. For the secondary outcome assessing patients reporting last known dose within the preferred time frame, only the R time was elevated in 2 (14.3%) patients. Lastly, in a subgroup analysis of patients with elevated low-molecular-weight heparin (LMWH) orAnti- Xa levels, the R time was the only parameter affected in 25% of patients. Conclusion: TEG values were typically not affected by rivaroxaban or apixaban use in an emergency department trauma population suggesting that TEG is not sensitive for Xa inhibitor detection and should not be relied upon for assessing anticoagulation in such settings.

    查看更多>>摘要:? 2021Background: Scapular fractures in the pediatric population are rare, and medical literature is lacking regarding these specific injuries in the pediatric population. Prior studies have shown that scapular fractures resulting from blunt chest trauma have been associated with significant morbidities in adults, and that a majority of scapular fractures are missed on chest X-ray (CXR) and seen on computerized tomography only (SOCTO). Further guidance is needed regarding the prevalence of coinciding injuries in the pediatric population and the modality for diagnosis. Objectives: The primary objectives of this study were to assess 1) the frequency of scapular fractures following blunt trauma in the pediatric cohort, 2) the frequency of other associated thoracic injuries, 3) the proportion on scapular fractures SOCTO. Methods: We conducted a retrospective cohort study with data obtained from our study site's Trauma Registry. Patients under 18 years receiving both a CXR and chest CT following blunt trauma or any patient diagnosed with a scapular fracture by any modality from January 2009 to December 2019 were included. Primary outcome variables were the presence of a scapular fracture diagnosed by any modality, absence of scapular fracture, and scapular fractures SOCTO. Charts were also reviewed for the following concurring injuries: 1) contusion/atelectasis, 2) pneumothorax, 3) hemothorax, 4) rib fracture, 5) other fracture, 6) vascular injury, 7) mediastinal injury, 8) diaphragm rupture, 9) foreign body, 10) incidental finding. Results: Of 12,826 charts of pediatric patients with blunt chest trauma, 1405 obtained both CXR and chest CT. Sixty (0.47%) were diagnosed with scapular fracture, and 48 (73.3%) of the fractures were SOCTO. The most commonly associated injuries were other fracture (88.3%), lung contusion/atelectasis (78.3%), pneumothorax (58.3%) and rib fracture (58.3%). Patients with scapular fractures had higher injury severity scores (ISS) and more frequently required surgery for other intrathoracic injuries. Only five patients required surgical management of the scapular fracture with the rest managed conservatively. Conclusion: Pediatric scapular fractures are rare and are often associated with other intrathoracic injury. A majority of scapula fractures are missed on CXR, but identification of the injury did not change management as most were treated conservatively.

    查看更多>>摘要:? 2021 Elsevier Inc.The current standard of care for acute frostbite rewarming is the use of a circulating warm water bath at a temperature of 37 °C to 39 °C. There is no standardized method to achieve this. Manual management of a warm water bath can be inefficient and time consuming. This case describes the clinical use of a sous vide cooking device to create and maintain a circulating warm water bath to rewarm acute frostbite. A 34 year-old male presented to the emergency department with acute frostbite. Each of the patient's feet were placed in a water bath with a sous vide device attached to the side of the basin and set to 38 °C. Temperatures were recorded every 2 m from 2 thermometers. Once target temperature was achieved, the extremities were rewarmed for 30 m. The water baths required an average of 25 m to reach target temperature and maintained the target temperature within ±1 °C for the duration of the rewarming. The extremities were clinically thawed in one session and there were no adverse events. The patient was seen by plastic and vascular surgery and admitted to the hospital for conservative management. He was discharged on hospital day 3 and did not require any amputations. A sous vide device can be used clinically to heat and maintain a water bath and successfully rewarm frostbitten extremities in one 30 m cycle. No adverse events were reported and providers rated this as a convenient method of water bath management.

    查看更多>>摘要:? 2021 The AuthorsBackground: Understanding the relationship between contrast agents and Kounis syndrome (KS) is mainly based on case reports. The purpose of this research is to explore the clinical characteristics of contrast media induced KS. Methods: We searched for contrast-induced KS case reports through Chinese and English databases from 1991 to October 31, 2021. Results: A total of 26 patients (19 men and 7 women,) were included, with a median age of 60 years (range 30–83). The contrast agents that cause KS mainly included gadolinium-based contrast agent (7 cases), iodine-containing contrast media (12 cases). KS mainly occurred within 30 min after administration and mainly manifests as chest pain and allergic reactions. Electrocardiogram (ECG) mainly showed ST elevation. Echocardiography mainly revealed normal. Coronary angiography showed normal, coronary vasospasm, stent thrombosis, occlusion and stenosis. After treatment with steroids, antihistamines and anti-ischemic therapy, 24 patients recovered completely and 2 patients died. Conclusions: KS is a rare adverse reaction of contrast media. Radiologists should recognize this rare but serious disease to ensure rapid diagnosis and proper management.

    查看更多>>摘要:? 2021 Elsevier Inc.Purpose: To explore the clinical value of serum calcium (Ca) in elderly patients with sepsis. Materials and methods: The clinical data and laboratory data of elderly patients with sepsis (n = 165) and elderly population for physical examination (n = 67) in a tertiary hospital from January 2020 to November 2020 were collected. We analyzed serum Ca levels in sepsis and septic shock firstly, and then continued to investigate them in the survival group and the death group. Meanwhile, we also assessed the correlation between serum Ca and PCT. Results: The serum Ca levels of the elderly patients with sepsis were lower than that of the control group (median 1.98 vs 2.31 mmol/L, P < 0.001), and the more severe the sepsis, the lower the serum Ca levels. Sepsis patients with decreased serum Ca had higher shock rate and mortality. There was a negative correlation between serum Ca and PCT (r = ?0.2957, P < 0.001). Conclusion: Serum Ca has a certain value for the early recognition of elderly patients with sepsis and the judgment of the severity of the disease.

    查看更多>>摘要:? 2021Objective: To assess the QTc interval variation after low-dose droperidol in a population of undifferentiated, stable, and non-agitated patients receiving droperidol in the emergency department. Methods: Prospective cohort study of patients aged ≥12 years of age who received low-dose droperidol (≤ 2.5 mg) for indications other than acute behavioral disturbances. QTc intervals were monitored in real-time during pre-specified observation periods in the ED. Primary outcome was variation of QTc interval after droperidol administration, defined as the maximum delta (change) of QTc interval. Other outcomes included proportion of patients with a QTc ≥ 500 ms after droperidol, delta ≥ +60 ms, and incidence of clinical adverse events. Patients were monitored up to 30 min after IV bolus and up to 46 min after infusion. Results: A total of 68 patients were included (mean age 42.1 years, 66.2% females). The median dose of droperidol was 1.875 mg (range 0.625 mg, 2.5 mg) and 94.1% received droperidol for headache management. Most patients received droperidol as a 2-min bolus (n = 41, 60.3%). The mean maximum delta of QTc interval after droperidol across all 68 patients was +29.9 ms (SD 15). A total of 12 patients (17.6%) experienced a QTc interval ≥ 500 ms during the observation period after droperidol, and 3 patients (4.4%) had a delta QTc ≥ +60 ms. There were no serious arrhythmias, such as TdP, or deaths among the 68 participants in this study (0/68). However, 13.2% (n = 9) had at least one non-serious adverse event including restlessness and/or anxiety. Conclusion: The QTc interval slightly increased after droperidol administration, but these prolongations were brief, mostly below 500 msec and did not lead to serious arrhythmias. The yield of continuous cardiac monitoring in patients receiving low doses of droperidol is likely low.

    查看更多>>摘要:? 2021 Elsevier Inc.Background: The optimal approach to blood pressure (BP) management in acute ischemic stroke remains unclear. The purpose of this study was to determine if an intermittent (labetalol or hydralazine) or continuous infusion (nicardipine or clevidipine) antihypertensive strategy facilitated timelier alteplase administration. Methods: Patients ≥18 years who presented to the emergency department (ED) between September 1, 2013 and August 31, 2020, received alteplase for acute ischemic stroke, and required BP management with an intravenous antihypertensive were included in this multicenter, retrospective cohort study. Exclusion criteria were initial administration of a non-study antihypertensive, initial study antihypertensive administration >2 hours prior to or any time following alteplase, or receipt of both an intermittent and continuous infusion antihypertensive prior to alteplase. The primary endpoint was the time from ED presentation to alteplase administration. Results: During the study period, 122 patients received an intermittent antihypertensive and 57 patients received a continuous infusion antihypertensive. The median door-to-needle time was 53 minutes for patients who received an intermittent antihypertensive compared to 57 minutes for those who received a continuous infusion antihypertensive (p=0.17). Secondarily, the proportion of patients who achieved the BP target <185/110 mmHg within 15 minutes of initial antihypertensive administration and the incidence of adverse events were similar between treatment groups. In cost analysis, intermittent antihypertensives were less expensive than continuous infusion antihypertensives ($2.20 vs. $71.40). Conclusions: Among patients with acute ischemic stroke and uncontrolled BP, the initial use of an intermittent or continuous infusion antihypertensive did not significantly impact the time to alteplase administration.

    查看更多>>摘要:? 2021 Elsevier Inc.Introduction: Computed tomography (CT) is a commonly used imaging modality in Emergency Departments (EDs), however its use is questionable in many low yield settings. The Emergency CT Head score (ECHS) is a recently published clinical tool that assists in stratifying the need for CT brain (CTB) for patients presenting without a history of trauma. We sought to validate this tool in an Australian ED setting. Methods: We prospectively evaluated 412 patients who received CTB without a history of trauma at a large Australian ED. We assessed them for the 4 main ECHS data points: focal neurological deficit on physical examination, new acute onset headache, transient neurological deficit, and a combination of new onset seizures with an altered conscious state. We examined their association with acute and chronic CTB findings. We then applied the ECHS to our data, calculating its sensitivity and its appropriateness at this single site via the calculation of a receiver operating curve (ROC). Results: 10.2% of all CTB performed were positive for an acute or chronic abnormality. Only sex (male) and focal motor deficit were independent predictors of positive CTB at univariate analysis. The ECHS did not perform as anticipated in our population, with a ROC area under the curve of 0.498. An ECHS score of >0, which has been proposed as the threshold to not require imaging, had sensitivity of only 83.3% in our population. Conclusions: Further research and validation is required in order to safely implement the ECHS clinical score in the Australian ED setting.
