RESUMO
Upper extremity acute limb ischemia (ALI) is a limb-threatening and potentially lethal pathology that is most commonly caused by vascular embolization. Outcomes of limb ischemia are time-sensitive due to the correlation between a longer time from symptom onset to intervention with a vastly higher risk of amputation. In this report, point of care ultrasound (POCUS) was utilized to rapidly diagnose a patient with a proximal right brachial artery embolic occlusion, prompting expedited surgical consultation and successful embolectomy. POCUS can provide a focused vascular examination of the limbs to expedite diagnosis of time-sensitive ALI and facilitate timely medical intervention and surgical consultation.
RESUMO
Rupture of an abdominal aortic aneurysm (AAA) is an immediately life-threatening phenomenon with substantial mortality. Although most AAAs are asymptomatic, an impending AAA rupture can be heralded by nonspecific symptoms and imaging findings on CT and point-of-care ultrasound (POCUS). In this report, we present a case of an 81-year-old male with an atypical presentation of an AAA with novel sonographic findings of imminent rupture on POCUS with Doppler that prompted successful emergent intervention. In the emergency department, imaging findings on aortic POCUS and CT imaging with angiography can facilitate assessment for impending aortic rupture, which can expedite appropriate disposition and potentially life-saving intervention.
RESUMO
A Morel-Lavallée lesion (MLL) is a rare, closed traumatic soft-tissue degloving injury that is often misdiagnosed. The mechanism that results in this lesion involves a shearing force that separates the hypodermis from underlying fascia, thereby disrupting perforating vascular and lymphatic vessels and resulting in a hemolymphatic fluid collection prone to infection and pseudocyst formation. We describe a case of a 70-year-old male with an initially missed MLL despite CT imaging that was ultimately diagnosed on point-of-care ultrasound (POCUS) on a second emergency department visit. Although an MLL is often misdiagnosed on radiography and CT imaging, POCUS is an expeditious imaging modality that can facilitate diagnosis of an MLL by visualizing specific sonographic characteristics.
RESUMO
Background Patients with difficult intravenous access (DIVA) requiring ultrasound-guided intravenous (USGIV) access have been associated with delays in treatment, imaging, and disposition in academic emergency department (ED) patient populations. Our objective in this study was to characterize differences in time to intravenous access, imaging, and disposition between patients with DIVA versus those without DIVA requiring USGIV access in a community ED while also assessing for DIVA-associated comorbidities. Methods A cross-sectional, observational analysis was performed on admitted ED patients evaluated from September 2 to September 31, 2022, at a community ED. Patients with DIVA were defined as patients with two failed attempts at traditional intravenous placement. These patients require USGIV placement per institutional protocol. Patients younger than 18 years of age, trauma admissions, repeated visits from the same patient, patients with missing data, and direct hospital admissions were excluded. Continuous variables were recorded with medians and included ED throughput measures of time to vascular access, contrast CT imaging, and disposition. Differences in median times between DIVA patients versus non-DIVA patients were assessed with the Mann-Whitney U-test. Categorical data involving comorbidities were reported as percentages, and differences in proportions between DIVA versus non-DIVA patients were assessed via chi-square tests. Multivariate logistic regression analysis evaluated for correlations between DIVA and times to access, contrast CT imaging, disposition, and significant covariates while adjusting for demographic information. Results A total of 1250 patients were included in this investigation (5.8% associated with DIVA requiring USGIV access). The median age of all subjects was 69 (interquartile range = 58, 79) with no significant difference between the DIVA and non-DIVA groups. Patients with DIVA were more likely to be female in comparison to patients without DIVA (65.3% and 51.2%, respectively, p < 0.05). Patients with a history of end-stage renal disease (ESRD) (p < 0.001), intravenous drug use (IVDU) (p < 0.001), and venous thromboembolism (p < 0.05) had statistically significant associations with DIVA. On regression analysis, patients with DIVA were more likely to have a history of ESRD with an odds ratio (OR) of 3.56 (95% confidence interval (CI): 1.62-7.81) and a history of IVDU with an OR of 14.29 (95% CI: 5.17-39.54). Patients with DIVA were associated with statistically significant greater median times to vascular access, contrast CT imaging, and disposition (p < 0.001 for time to access and disposition and p < 0.01 for time to contrast CT imaging). Conclusion In this study, DIVA cases requiring USGIV access were positively associated with significantly longer times to access, contrast CT imaging, and disposition compared to patients without DIVA at our community ED. Comorbidities such as IVDU and ESRD had statistically significant associations with DIVA requiring USGIV access.
RESUMO
A 27-year-old female grava1 para 0 presented to the emergency department with complaints of intractable nausea and vomiting associated with fatigue and shortness of breath for the past 2 weeks with concerns for pregnancy. Physical exam was benign. Labs were significant for a ß-hcg level of 348,260 mIU/mL. Ultrasonography showed a 12.4 pelvic mass possibly arriving from the anterior uterus concerning for fibroid. US also showed an anechoic focus suggestive of a gestational sac measuring 2.09 cm. The presentation was concerning for hyperemesis gravidarum due to molar pregnancy.
RESUMO
The authors present a description of the procedure cart they designed for their Emergency Department. This project was in response to the inefficiencies in having to gather supplies from various locations to get set up. A complete description including each of the drawer contents is provided to allow others to easily replicate a tool that saved the authors much time and frustration in daily practice.
RESUMO
Large bowel obstruction (LBO) is a life-threatening condition seen most often in the geriatric population. LBO can present with nonspecific abdominal pain that can overlap with other pathologies, such as abdominal infection, acute aortic disease, intestinal perforation, and atypical acute coronary syndrome in the geriatric population. Delays in diagnosis of colonic obstruction result in significant mortality due to complications involving bowel necrosis, perforation, and sepsis. In the emergency department (ED), abdominal point-of-care ultrasound (POCUS) can diagnose LBO and facilitate the assessment of the wide differential inherent to elderly abdominal pain. The authors report a rare ED application of abdominal POCUS to facilitate rapid diagnosis of an LBO secondary to rectal cancer.
RESUMO
Penetrating aortic ulcer (PAU) complicated by an intramural hematoma is a rare and potentially life-threatening emergency department (ED) presentation that is defined by progressive ulceration through the intima layer into the media layer of the aorta. Symptomatic PAUs can be clinically indistinguishable from other life-threatening pathologies such as aortic dissection, acute coronary syndrome (ACS), intrabdominal catastrophes as well as less lethal processes such as musculoskeletal back pain. Given the potential of PAUs to result in lethal aortic rupture and dissection, the emergency provider should maintain a high index of suspicion in patients with risk factors for aortic pathologies and utilize diagnostic modalities such as point-of-care ultrasound (POCUS) to expedite diagnosis.
RESUMO
Objective: Vaccine hesitancy among healthcare providers can compromise public confidence in vaccination during the ongoing COVID-19 global epidemic and increase susceptibility to life-threatening disease. We sought to investigate predictors of openness to vaccination among healthcare workers who choose not to be vaccinated against COVID-19 in order to explore potential solutions. Methods: Physicians, physician assistants, and nurses who chose not to be vaccinated were surveyed to decipher reasons for vaccine refusal and personal loss due to the virus along with demographic variables. Multivariate logistic regression analysis evaluated whether provider role, parenthood, and death of family or friends were associated with strong versus relative vaccine refusal. Results: The predominant reasons for vaccine hesitancy in this cohort of health care workers who had access to, but chose not to be vaccinated (n=500) were a concern for vaccine side effects (69.6%) and the belief that the vaccines are inadequately studied (61.6%). Being a physician, a parent, and having no experience of death in the family or friends had 2.64 times (95% CI: 1.65-4.23, p < 0.001), 1.72 times (95% CI: 1.05-2.81, p = 0.032), and 1.70 times (95% CI: 1.06-2.72, p = 0.028) the odds of strong vaccine refusal, respectively. Older age (35 and up) respondents were 1.83 times (95% CI: 1.24-2.68, p = 0.002) more likely to be open to vaccination.
RESUMO
We herein report a case of an 18-year-old female with Kawasaki disease who presented to the emergency department with epigastric abdominal pain and was subsequently found to have free fluid present in her abdomen visualized on bedside Focused Assessment with Sonography for Trauma (FAST) exam. Kawasaki disease is an acute vasculitis syndrome that primarily affects children and can have serious complications such as coronary artery aneurysms. The use of ultrasound in emergency departments is rapidly increasing, with the FAST being one of the most commonly performed bedside ultrasound examinations. FAST exams are most commonly performed in trauma patients as well as being part of the Advanced Trauma Life Support (ATLS) protocol. However, this case demonstrated that the FAST exam can also have application in other clinical scenarios and patient presentations where there is clinical suspicion of free intra-abdominal fluid.
RESUMO
Extremity trauma is a common emergency department presentation. The authors report a case of an elderly woman who sustained a trimalleolar ankle fracture. Emergency department care includes stabilization of the fracture with a splint, with careful assessment of neurovascular status. Trimalleolar fractures are unstable and thus almost always will require surgical repair. This is true even for elderly patients and those with co-morbidities. Patients who do not get a surgical repair for these fractures are at risk for significant morbidity, including compartment syndrome, arthritis, malunion, and loss of mobility.
RESUMO
This study examines the relationship between serial serum lactate levels and in-hospital mortality in an adult cohort of emergency department patients with severe sepsis or septic shock. Of the 164 patients in the cohort, 130 also got three-hour lactate in addition to the initial one. The median initial lactate was 3.01 (interquartile range [IQR]: 1.71-4.62). The median repeat lactate was 2.58 (IQR: 1.4-3.9). The in-hospital death rate was 23% for men and 29% for women. The delta lactate was significantly higher in women (P=0.0070), driven by a lower initial lactate (P=0.0277). In a multivariate regression model controlled for age and gender, a statistically significant correlation was noted between an increase in the delta lactate and in-hospital death (P=0.0323; R2=11.3%). The results of this single-center study suggest that an increase in serum lactic acid is significantly associated with higher in-hospital death.
RESUMO
Objective The objective of this study was to improve sepsis bundle compliance via an educational intervention in our emergency department (ED). Methods This was a before and after study. Historical data on sepsis bundle compliance was obtained from our quality officer. Data were collected for 30 consecutive days to compare sepsis bundle compliance rates before and after the intervention. Descriptive statistics were compiled, and the z-test for proportions was used to calculate statistical significance. The intervention was two-fold: 1) a bright yellow card with sepsis criteria listed was posted on all ED workstation computers and 2) there was a daily email blast for one month with "sepsis facts." These email blasts were short pearls that highlighted the importance of recognizing and treating sepsis. Results The sepsis bundle compliance rates in the month prior to the intervention was 38%. In the month during the targeted intervention, the compliance rate increased to 56%. There was a statistically significant increase in bundle compliance rates during the intervention (p=0.0399). We also administered a survey to the ED attendings and residents following the completion of the study to assess whether they perceived that our intervention was helping them increase compliance with ordering the sepsis bundle. The response rate was 94%. To the question "Did you feel the sepsis cards placed on the workstations make you more likely to consider sepsis earlier in patients under your care in the emergency department?" 70% answered agree or strongly agree. To the question "Were you more likely to order the sepsis bundle after receiving the daily "Sepsis Facts"?" 29% were neutral while 59% answered agree or strongly agree. Finally, to the question "Did you feel the sepsis cards and "sepsis facts" help you improve the care of Septic patients in the emergency department?" 76% answered agree or strongly agree. Conclusion Sepsis criteria reminders and email blasts highlighting the importance of treating and recognizing sepsis can improve compliance with sepsis bundle ordering within the emergency department.
