RESUMO

PURPOSE: This article summarizes emerging nontraditional therapies administered via the nebulization route for use in the emergency department (ED). SUMMARY: Although traditional routes of medication administration (eg, intravenous) have been the mainstay of administration modalities for decades, these routes may not be appropriate for all patients. Nowhere is this more readily apparent than in the ED setting, where patients with a variety of presentations receive care. One unique route for medication administration that has increasingly gained popularity in the ED is that of aerosolized drug delivery. This route holds promise as direct delivery of medications to the site of action could yield a more rapid and effective therapeutic response while also minimizing systemic adverse effects by utilizing a fraction of the systemic dose. Medication administration via nebulization also provides an alternative that is conducive to rapid, less invasive access, which is advantageous in the emergent setting of the ED. This review is intended to analyze the existing literature regarding this route of administration, including the nuances that can impact drug efficacy, as well as the available literature regarding novel, noncommercial nebulized medication therapy given in the ED. CONCLUSION: Multiple medications have been investigated for administration via this route, and when implementing any of these therapies several practical considerations must be taken into account, from medication preparation to administration, to ensure optimal efficacy while minimizing adverse effects. The pharmacist is an essential bedside team member in these scenarios to assist with navigating unique and complex nuances of this therapy as they develop.

RESUMO

Primary literature detailing updated management principles of acute ischemic stroke outpaces current guidelines, resulting in heterogenous practices. Recent advancements in neuroimaging have shifted treatment from a time-based approach to an individualized, image-guided appraisal directed by the presence or absence of salvageable brain tissue. In addition, tenecteplase appears to be a safe and effective for the treatment of acute ischemic stroke and is becoming an attractive agent due to its practical administration. Several factors must be accounted for when implementing tenecteplase into the health-system including cost, education, and changes in clinician workflows. Larger studies with broad patient populations are needed to more definitively evaluate whether intravenous thrombolytics should be used in combination with endovascular thrombectomy in patients with anterior large-vessel occlusions. Although debate regarding the safety and efficacy of various endovascular therapies, delays encountered in the identification, triage, and care of acute ischemic stroke patients increase the likelihood of necrotic core lesion development and loss of salvageable penumbra.

RESUMO

Phytolacca americana, known more commonly as "pokeweed", is a large perennial plant found ubiquitously throughout the United States. Despite known toxicities, characterization of pokeweed exposure demographics, symptoms, treatments, and outcomes is currently limited. The objective of this study is to describe human pokeweed exposures, treatments, and outcomes, in the state of Kentucky, between 2000 and 2019. The National Poison Database System was queried for all Phytolacca americana exposures in the state of Kentucky between 2000 and 2019. After the removal of non-human cases, investigators independently reviewed data to ensure all coding was appropriate per the standards set forth by NPDS. The primary objective of this study was to describe pokeweed exposure demographics within the state of Kentucky during the previously established timeframe. Secondary objectives included characterizing pokeweed treatment trends and evaluating their affiliated medical outcomes. 1669 cases of human pokeweed exposure were reported. Patients were predominantly young in age, with a median age of 3 years reported. The majority of patients were male (54.9%), with unintentional exposures representing most exposure reasons (97.2%). Oral ingestion of plant material represented the bulk of the exposure route (98.3%), with pokeberries most often implicated in these cases (93.9%). Exposures were generally well tolerated. 239 total adverse events were noted during the timeframe. Abdominal pain, nausea, vomiting, and diarrhea were most common. Dermal exposures resulted in cutaneous edema, pain, and swelling. Treatments were mainly supportive, with no deaths reported during the study timeframe. In conclusion, Phytolacca americana is commonly encountered in the United States. In this observational study, patients most heavily implicated in pokeweed exposures are young males. Oral ingestion was most commonly reported, with berries most often implicated. Exposures are generally well tolerated, with gastrointestinal symptoms most frequently reported. Cutaneous exposures represent an underappreciated exposure route. Treatments are largely supportive in nature.

RESUMO

INTRODUCTION: Acetaminophen is a commonly used analgesic and antipyretic, with the potential to cause significant injury when ingested in toxic amounts. Although the antidote n-acetylcysteine (NAC) is available, evidence supporting dose recommendations for patients weighing over 100 kg are lacking. We performed a retrospective, multi-center analysis to determine if a capped NAC dosing scheme is similar to a non-capped dosing scheme in patients weighing over 100 kg. METHODS: Between January 2009 and January 2016, we identified patients presenting to 12 different centers who were evaluated for acetaminophen poisoning treatment. Patients must have weighed greater than 100 kg and were evaluated and identified as needing treatment for acetaminophen-related poisoning with NAC. The primary outcome was occurrence of hepatic injury, defined as an AST or ALT ≥ 100 IU/L. Secondary endpoints included number of drug-related adverse events, occurrence of hepatotoxicity, cumulative NAC dose, regimen cost, length of hospital and intensive care unit stays, and in-hospital mortality. RESULTS: There were 83 patients identified as meeting the pre-specified inclusion and exclusion criteria. A capped NAC dosing scheme resulted in no difference in hepatic injury when compared to a non-capped regimen (49.4% vs 50%, p = 1.000). The capped dosage regimen was associated with a lower cumulative dose (285.2 mg/kg vs 304.6 mg/kg, p < 0.001) and cost. No other statistically significant differences were identified among the secondary endpoints. CONCLUSION: A capped NAC dosing scheme was not associated with higher rates of hepatic injury or hepatotoxicity in obese patients in the setting of acetaminophen poisoning when compared to a non-capped regimen. Further research is needed to verify these results.

RESUMO

INTRODUCTION: Civilian gunshot open-fracture injuries portray a significant health burden to patients. Use of antibiotics is endorsed by guideline recommendations for the prevention of post-traumatic infections, however, antimicrobial selection and their associated outcomes remains unclear. Therefore, we sought to compare infectious and other clinical outcomes between three antimicrobial cohorts in patients with gunshot-related fractures requiring operative intervention. MATERIALS AND METHODS: Patients were identified by retrospectively querying the University of Kentucky Trauma Registry for gunshot wound victims. A narrow regimen, an expanded gram-negative regimen, and a regimen containing a fluoroquinolone antimicrobial were identified for comparison. The primary outcome was a composite of infections at or before 14 days of hospitalization. Secondary endpoints included hospital length of stay, incidence of multidrug resistant bacteria and methicillin-resistant Staphylococcus aureus colonization, number of drug-related adverse events, number of Clostridium difficile infections, and 30-day mortality. RESULTS: 252 patients were selected for inclusion: 126 in the narrow regimen, 49 in the expanded gram-negative regimen, and 77 in the fluoroquinolone-based regimen. There were no statistical differences in the primary endpoint of early infectious outcomes between groups (p = 0.1797). The expanded gram-negative regimen was associated with increased hospital length of stay, and increased incidence of multi-drug resistant bacteria and methicillin-resistant Staphylococcus aureus colonization. There were no statistically significant differences in any of the remaining secondary endpoints. CONCLUSION: In this study evaluating civilian gunshot trauma, broad spectrum antibiotic coverage was not associated with improvements in post-traumatic infections. A randomized trial is needed to confirm these results.

RESUMO

Acetaminophen poisoning is the leading cause of liver transplantation within the United States, accounting for nearly 56,000 emergency department patient visits each year. Although n-acetylcysteine is commonly successful in preventing acetaminophen toxicity when given in a timely manner, reports do exist demonstrating n-acetylcysteine therapy failure, commonly in the setting of a massive ingestion. We present the use of a novel antidote cocktail of n-acetylcysteine, fomepizole, and hemodialysis to treat a massive acetaminophen ingestion. A 55-year old male with a past medical history significant for bipolar disorder and past suicidal ideation presented to the emergency department after being found unresponsive at home. Medical workup was significant for an estimated seven-hour acetaminophen level of 883 mcg/mL, with concomitant metabolic acidosis. The patient was diagnosed with severe acetaminophen poisoning and was promptly administered n-acetylcysteine. Due to the severity of the patient's ingestion and the concern for additional coingestants, the patient was also given fomepizole therapy and later underwent hemodialysis for more rapid toxin clearance. After a four-day stay in the hospital the patient was discharged to a mental-health facility with no signs of systemic injury.

RESUMO

Stevens-Johnson syndrome and toxic epidermal necrolysis represent a spectrum of severe cutaneous adverse reactions that carry the potential for severe, long-term adverse effects, including death. Although medications are most commonly implicated in the development of these diseases, other factors, including infection and genetics, play a role. Management is generally supportive in nature and includes maintenance of the patient's airway, breathing, and circulation. Special disease considerations include the use of skin barrier management, unique infection prevention measures, and systemic immunomodulatory therapies.

RESUMO

OBJECTIVES: Mounting evidence has shown that critically ill patients are commonly thiamine deficient. We sought to test the hypothesis that critically ill patients with septic shock exposed to thiamine would demonstrate improved lactate clearance and more favorable clinical outcomes compared with those not receiving thiamine. DESIGN: Retrospective, single-center, matched cohort study. SETTING: Tertiary care academic medical center. PATIENTS: Adult patients admitted with an International Classification of Diseases, 9th Edition, or International Classification of Diseases, 10th Edition, diagnosis code of septic shock to either the medicine or surgery ICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patients who received IV thiamine supplementation within 24 hours of hospital admission were identified and compared with a matched cohort of patients not receiving thiamine. The primary objective was to determine if thiamine administration was associated with a reduced time to lactate clearance in septic shock. Secondary outcomes included 28-day mortality, acute kidney injury, and need for renal replacement therapy, and vasopressor and mechanical ventilation-free days. Two-thousand two-hundred seventy-two patients were screened, of whom 1,049 were eligible. The study consisted of 123 thiamine-treated patients matched with 246 patients who did not receive thiamine. Based on the Fine-Gray survival model, treatment with thiamine was associated with an improved likelihood of lactate clearance (subdistribution hazard ratio, 1.307; 95% CI, 1.002-1.704). Thiamine administration was also associated with a reduction in 28-day mortality (hazard ratio, 0.666; 95% CI, 0.490-0.905). There were no differences in any secondary outcomes. CONCLUSIONS: Thiamine administration within 24 hours of admission in patients presenting with septic shock was associated with improved lactate clearance and a reduction in 28-day mortality compared with matched controls.
