RESUMEN

Objective: To evaluate the current body of literature pertaining to the use of ocular point-of-care ultrasound (POCUS) in the emergency department. Methods: A comprehensive literature search was conducted on SCOPUS, Web of Science, MEDLINE, and Cochrane CENTRAL. Inclusion criteria included studies written in English only and primary clinical studies involving ocular POCUS scans in an emergency department setting. Exclusion criteria included non-primary studies (e.g. reviews or case reports), studies written in a non-English language, non-human studies, studies performed in a non-emergency setting, studies involving non-POCUS ocular ultrasound modalities, or studies published outside of the last decade. Data extraction was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. Results: The initial search yielded 391 results with 153 duplicates. Of the remaining 238 studies selected for retrieval and screening, 24 met inclusion criteria. These 24 included studies encompassed 2448 patients across prospective, retrospective, cross sectional, and case series study designs. We found that a majority of included studies focus on the use of POCUS in the emergency department to measure ONSD as a proxy for papilledema and metabolic aberrations, while a minority use ocular POCUS to assist in the diagnosis of orbital fractures or posterior segment pathology. Conclusion: The vast majority of articles investigating the use of ocular POCUS in recent years emphasize its utility in measuring ONSD and fluctuations in intracranial pressure, though additional outcomes of interest include posterior segment, orbit, and globe pathology.

RESUMEN

Abdominal pain is one of the most common presenting chief complaints in the emergency department (ED). Erector spinae plane block (ESPB) is an ultrasound-guided nerve block with proven effectiveness in treating visceral and somatic abdominal pain. Despite the increasing popularity of ESPB, its role in the management of non-surgical abdominal pain has not yet been characterized. Our scoping review aims to review the current literature on the safety and efficacy of ESPB in the management of patients experiencing intractable, non-surgical abdominal pain. We searched PubMed and Scopus to evaluate the existing literature on ESPB for non-surgical abdominal pain. Reviewers screened 30 titles and abstracts that met the predefined inclusion and exclusion criteria. Following initial screening, 24 articles underwent full-text review. Two reviewers also screened references included in each study. A total of 14 journal articles were reviewed, including 12 case-based studies, one systematic review, and one narrative review of ESPB in the treatment of non-surgical abdominal pain. All cases described the successful use of ESPB in treating abdominal pain refractory to oral or intravenous analgesic medications, and each case reported no complications. This scoping review provides support for ESPB in the management of intractable, non-surgical abdominal pain. ESPB demonstrates efficacy in alleviating various conditions such as functional abdominal pain, renal colic, pancreatitis, herpetic pain, and cancer-related pain. Theoretical risks such as pneumothorax, bleeding, and infection are possible, although the studies reviewed did not report such complications.

RESUMEN

Epiglottitis is historically known to be a disease of childhood. However, since the implementation of the Haemophilus influenzae type B vaccination, there has been an increasing incidence within the adult population. This is a case report of a 36-year-old male who presented to the emergency department (ED) in severe respiratory distress with complaints of a sore throat, shortness of breath, odynophagia, dysphagia, and hoarseness. Physical exam revealed biphasic stridor, tachycardia, tachypnea, and an erythematous uvula. Imaging of his neck revealed findings consistent with epiglottitis containing nonspecific air. The patient was rapidly intubated, started on broad spectrum antibiotics and dexamethasone. He was admitted for intensive medical management with Otolaryngology consultation. This case report highlights the importance of rapid recognition and diagnosis of epiglottitis in an adult population to prevent morbidity and mortality. Topics: Epiglottitis, stridor, odynophagia, dysphagia, Haemophilus influenzae, group C streptococci, thumb-print sign, intubation.

RESUMEN

BACKGROUND: Point-of-care ocular ultrasound in the emergency department (ED) is an effective tool for promptly evaluating for several vision-threatening etiologies and can be used to identify more slowly progressing etiologies as well, such as cataract formation within the lens. CASE REPORT: A 62-year-old female presented to the ED with a two-day history of painless vision loss of the left eye as well as reduced vision for the prior 30 days. CONCLUSION: Point-of-care ultrasound was performed and showed calcification of the lens consistent with cataract.

RESUMEN

PURPOSE: The purpose of this paper is to illustrate delirium as a possible consequence of the application of symptom-triggered therapy for alcohol withdrawal and to explore alternative treatment modalities. In the management of alcohol withdrawal syndrome, symptom-triggered therapy directs nursing staff to regularly assess patients using standardized instruments, such as the Clinical Institute for Withdrawal Assessment of Alcohol, Revised (CIWA-Ar), and administer benzodiazepines at symptom severity thresholds. Symptom-triggered therapy has been shown to lower total benzodiazepine dosage and treatment duration relative to fixed dosage tapers (Daeppen et al., 2002). However, CIWA-Ar has important limitations. Because of its reliance on patient reporting, it is inappropriate for nonverbal patients, non-English speakers (in the absence of readily available translators) and patients in confusional states including delirium and psychosis. Importantly, it also relies on the appropriate selection of patients and considering alternate etiologies for signs and symptoms also associated with alcohol withdrawal. DESIGN/METHODOLOGY/APPROACH: The authors report a case of a 47-year-old male admitted for cardiac arrest because of benzodiazepine and alcohol overdose who developed worsening delirium on CIWA-Ar protocol. FINDINGS: While symptom-triggered therapy through instruments such as the CIWA-Ar protocol has shown to lower total benzodiazepine dosage and treatment duration in patients in alcohol withdrawal, over-reliance on such tools may also lead providers to overlook other causes of delirium. ORIGINALITY/VALUE: This case illustrates the necessity for providers to consider using other available assessment and treatment options including objective alcohol withdrawal scales, fixed benzodiazepine dosage tapers and even antiepileptic medications in select patients.

RESUMEN

PURPOSE: Ultrasound is considered a preferred first-line imaging technique for the assessment of kidney function. The potential relationship between tobacco smoke exposure and ultrasound-measured renal characteristics has yet to be explored. We hypothesized that exposure to tobacco smoke would be associated with reduced kidney dimensions. MATERIALS AND METHODS: This was a cross-sectional study that included all individuals over age 18 at a single site in Mojokerto, Indonesia. A questionnaire was used to assess prior history and environmental exposure, and blinded evaluators performed ultrasound assessments. Six kidney parameters (length, width, and parenchymal thickness of each kidney) were considered as dependent variables, and statistical relationships were assessed using multivariate analysis. Echogenicity was evaluated using a 5-point grading scale described previously. RESULTS: Of the 445 participants assessed, a total of 138 male and 269 female subjects were included in the final analysis. There was a statistically significant association between kidney measures and the following independent variables: pack years smoking (p < 0.001), height (p < 0.001), weight (p < 0.001), and beginning to smoke at the age of 25 or younger (p < 0.001). There was not a statistically significant association between kidney measures and hypertension (p > 0.05) or diabetes (p > 0.05). Echogenicity was similar among all smoking groups. CONCLUSION: Kidney dimensions were decreased in individuals with increased smoking history. This association is notable, particularly given that statistically significant associations were not observed between renal dimensions and hypertension or diabetes. The null findings using echogenicity are consistent with previous studies.

RESUMEN

PURPOSE: In the Indonesian health-care system, nurses and midwives often serve as the primary health-care providers due to physician shortages. Seeking to address the need for medical care in resource-limited environments, some have advocated for portable equipment in the hands of health-care providers. We hypothesized that medical students are able to effectively teach point-of-care ultrasound (POCUS) to physicians, nurses, and midwives in rural Indonesia. METHODS: We conducted a prospective, observational study using health-care practitioners from a clinic and accredited school for nursing and midwifery in Mojokerto, East Java, Indonesia. Enrolled practitioners took part in a 4-week POCUS course followed by postinstructional testing. RESULTS: A total of 55 health-care practitioners completed the course. This included 19 physicians, 13 nurses, and 19 midwives. Of the 55 clinicians, 43 (72%) passed the course and 12 (28%) failed. CONCLUSIONS: Physicians, nurses, and midwives in rural Indonesia showed significant acquisition of ultrasound (US) knowledge and skills following a 4-week US course. Following training, all three groups displayed skills in practical US use during a postcourse practical examination. This is one of the first studies to assess the efficacy of medical students teaching POCUS to midwives and nurses.
