RESUMEN
BACKGROUND: Urinary tract infections (UTIs) are commonly treated in the emergency department (ED), and unfortunately, resistance to first-line agents is increasing. OBJECTIVES: To characterize treatment of pyelonephritis in a nationally representative sample of ED patients and to identify patient- and treatment-specific factors associated with receiving initial inactive antibiotics. METHODS: We conducted a multicentre, observational cohort study utilizing the Emergency Medicine PHARMacotherapy Research NETwork (EMPHARM-NET), comprising 15 geographically diverse US EDs. All patients ≥18â years of age with a diagnosis of pyelonephritis between 2018 and 2020 were included. The primary endpoint was the proportion of patients who received initial inactive empirical antibiotic therapy and to identify predictive factors of inactive antibiotic therapy. RESULTS: Of the 3714 patients evaluated, 223 had culture-positive pyelonephritis. Median patient age was 50.1â years and patients were mostly female (78.3%). Overall, 40.4% of patients received an IV antibiotic, most commonly ceftriaxone (86.7%). The most frequently prescribed antibiotics were cefalexin (31.8%), ciprofloxacin (14.3%), cefdinir (13.5%) and trimethoprim/sulfamethoxazole (12.6%). Overall, 10.3% of patients received initial inactive therapy. After adjustment in a multivariable analysis, long-acting IV antibiotic was predictive of inactive therapy (OR 0.23, 95% CI 0.07-0.83). CONCLUSIONS: In our prospective, multicentre observational study, we found that only 40.4% of patients with pyelonephritis received empirical IV antibiotics in the ED, contributing to inactive therapy. Receipt of long-acting IV antibiotics was independently associated with a decreased rate of initial inactive therapy. This reinforces guideline recommendations to administer long-acting IV antibiotics empirically in the ED upon suspicion of pyelonephritis.

OBJECTIVES: Although the potential dangers of hyperchloremia from resuscitation fluids continue to emerge, no study to date has considered the contribution of medication diluents to cumulative volume and hyperchloremia. This study compares saline versus dextrose 5% in water as the primary medication diluent and the occurrence of hyperchloremia in critically ill patients. DESIGN: Prospective, open-label, sequential period pilot study. SETTING: Medical ICU of a large academic medical center. PATIENTS: Adult patients admitted to the medical ICU were eligible for inclusion. Patients who were admitted for less than 48 hours, less than 18 years old, pregnant, incarcerated, or who had brain injury were excluded. INTERVENTIONS: Saline as the primary medication diluent for 2 months followed by dextrose 5% in water as the primary medication diluent for 2 months. MEASUREMENTS AND MAIN RESULTS: A total of 426 patients were included, 216 in the saline group and 210 in the dextrose 5% in water group. Medication diluents accounted for 63% of the total IV volume over the observation period. In the saline group, 17.9% developed hyperchloremia compared with 10.5% in the dextrose 5% in water group (p = 0.037), which was statistically significant in multivariable analysis (odds ratio, 0.50; 95% CI, 0.26-0.94; p = 0.031). In the saline group, 34.2% developed acute kidney injury versus 24.5% in the dextrose 5% in water group (p = 0.035); however, this was not statistically significant when adjusting for baseline covariates. No other significant differences in dysnatremias, insulin requirements, glucose control, ICU length of stay, or ICU mortality were observed. CONCLUSIONS: This study identified that medication diluents contribute substantially to the total IV volume received by critically ill patients. Saline as the primary medication diluent compared with dextrose 5% in water is associated with hyperchloremia, a possible risk factor for acute kidney injury.

DISCLAIMER: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE: Vasoactive medications are used during advanced cardiac life support (ACLS) to shunt oxygenated blood to vital organs and after return of spontaneous circulation (ROSC) to maintain hemodynamic goals. However, limited evidence exists to support vasoactive medication recommendations in such scenarios, and it is unknown how practices vary among emergency departments across the US. METHODS: A survey questionnaire (15 questions) was electronically distributed to emergency medicine pharmacists (EMPs) in the US through various professional listservs. Demographic information, American Heart Association ACLS algorithm medication use, and use of continuous vasopressor infusions and adjunct medications following ROSC were assessed and are reported descriptively. RESULTS: The survey was distributed to 764 EMPs, with a 23% response rate from a wide geographic distribution and 48% of respondents practicing in academic medical centers. Epinephrine dosing and administration during cardiac arrest were reported by most to be in accordance with ACLS cardiac arrest algorithms. Calcium, magnesium sulfate, and sodium bicarbonate were the most common adjunct intravenous medications given during cardiac arrest. Norepinephrine was the first-choice vasopressor (81%) for post-ROSC hypotension, while epinephrine was preferred less frequently (17%). Antibiotics and sodium bicarbonate were the most frequently administered post-ROSC adjunct medications. CONCLUSION: This survey of a geographically diverse group of EMPs demonstrated high ACLS algorithm adherence for epinephrine during cardiac arrest with frequent additional administration of nonalgorithm medications. Sodium bicarbonate and calcium were the most frequently administered adjunct medications during cardiac arrest, while sodium bicarbonate and antibiotics were the most frequently used adjunct medications following ROSC. Norepinephrine was the most commonly used vasopressor following ROSC.
RESUMEN
INTRODUCTION: Phantom limb pain (PLP) is a poorly understood phenomenon experienced by amputees. The pain is typically classified as neuropathic, and there is no established first-line therapy. Droperidol is an antipsychotic with a wide array of pharmacologic activity including gamma-aminobutyric acid-A channel modulation, µ opioid receptor potentiation, dopamine-2-receptor blockade, and alpha-2-receptor agonism. Due to this broad therapeutic activity, droperidol is used for many off-label indications. CASE REPORT: Our patient was a 25-year-old male with a history of lower limb amputation who presented for evaluation and management of an acute exacerbation of PLP. On arrival, the patient was in 10/10 pain (numeric pain rating scale) described as cramping and burning. He had been previously successfully managed with subdissociative ketamine. However, during a recent exacerbation he experienced an emergence reaction to ketamine. Literature guiding pharmacotherapy in the management of PLP is sparse and of low quality. Based on the prior emergence reaction to subdissociative ketamine we explored other pharmacotherapy options. Droperidol has a wide array of pharmacologic activity and is used off label for the management of some pain syndromes. Therefore, we administered an intravenous dose of droperidol 5 milligrams. Approximately 15 minutes after receiving droperidol the patient's pain was visibly improved, and 30 minutes later he rated his pain at 3/10. CONCLUSION: The success in treating this patient provides encouragement for future research and bolsters confidence that droperidol could be another tool in the management of complex pain syndromes.
RESUMEN
BACKGROUND: Prolong effects of non-depolarizing neuromuscular blocking agents after rapid sequence intubation may prevent meaningful neurological examination, delaying appropriate diagnosis and neurosurgical intervention. Sugammadex is indicated for the reversal of neuromuscular blockade induced by rocuronium. OBJECTIVE: The objective of this study was to evaluate low- (2 mg/kg) vs standard-dose (4 mg/kg) sugammadex for rocuronium-induced deep neuromuscular blockade reversal in the emergency department (ED) by achieving a post-treatment train-of-four (TOF) of 4 to facilitate neurological examination. METHODS: This was a single-center, retrospective, cohort study evaluating low-vs standard-dose sugammadex for neuromuscular blockade reversal in the ED. RESULTS: 34 patients were identified within the designated time period, 24 of which were included in the final analysis ([n = 9 low-dose], [n = 15 standard-dose]). Median sugammadex doses were 2.3 mg/kg and 4.1 mg/kg for low- and standard-dose, respectively. The majority of patients presented for intraparenchymal hemorrhage (54.2%). No significant difference in success rate of NMBA reversal was found between low- and standard-dose sugammadex ([100.0% vs 93.3%], P = 1.000). A total of 9 patients had a neurosurgical procedure performed after sugammadex administration. Low-dose sugammadex was associated with significantly less acquisition cost compared to the standard dose (P < .001). CONCLUSION: Low- (2 mg/kg) and standard-dose (4 mg/kg) sugammadex successfully reversed rocuronium-induced deep neuromuscular blockade in the ED by achieving a post-treatment TOF of 4 to facilitate neurologic examination. Low-dose sugammadex may be a viable option for deep NMBA reversal in the ED and is associated with decreased institutional cost.
RESUMEN
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.
RESUMEN
BACKGROUND: Uropathogen resistance, fluoroquinolone-resistance (FQR), and extended spectrum beta-lactamase (ESBL), has been observed to be emerging worldwide with prevalences above recommended thresholds for routine empirical treatment. The primary aim of our study was to determine the prevalence of FQR from a geographically diverse sample of United States emergency departments (EDs). METHODS: We conducted a multi-center, observational cohort study using a network of 15 geographically diverse US EDs. All patients ≥18 years of age with the primary or secondary diagnosis of urinary tract infection (UTI) in the ED identified using International Classification of Diseases (ICD-10) diagnosis code of cystitis, pyelonephritis, or UTI from 2018 to 2020 were included. We calculated descriptive statistics for uropathogens and susceptibilities. Logistic regression analysis was used to identify antimicrobial resistance risk factors associated with FQR Escherichia coli. RESULTS: Among 3779 patients who met inclusion criteria, median age was 62.9 years (interquartile range [IQR]: 41-77.6) and 76.3% were female. The most common diagnoses were complicated (41.2%) and uncomplicated cystitis (40.3%). E. coli was the most common pathogen (63.2%), followed by Klebsiella pneumoniae (13.2%) and Enterococcus species (5.8%). Across all sites, overall E. coli FQ-resistance prevalence was 22.1%, ranging from 10.5 to 29.7% by site. The prevalence of ESBL-producing uropathogen was 7.4%, ranging from 3.6% to 11.6% by site. Previous IV or oral antimicrobial use in the past 90-days and history of a multi-drug resistant pathogen were associated with FQ-resistant E. coli (odds ratio [OR] 2.68, 95% confidence interval [CI]: 2.04-3.51, and OR 6.93, 95% CI: 4.95-9.70, respectively). Of the patients who had FQ-resistant E. coli or an ESBL-producing uropathogen isolated, 116 (37.1%) and 61 (36.7%) did not have any documented risk factors for resistance. CONCLUSION: FQ-resistant E. coli is widely prevalent across US sites highlighting the need for ongoing monitoring of antimicrobial resistance and, at some locations, modification of empirical treatments.

Tranexamic acid (TXA) is an antifibrinolytic commonly used to reduce blood loss due to surgical procedures, heavy menstruation, trauma, bleeding disorders, among other uses. Possible adverse reactions associated with TXA include abdominal pain, headache, fatigue, cerebral thrombosis, dizziness, retinal artery occlusion, chromatopsia, and more. We present a case of acute color vision disturbance developed soon after initiation of oral TXA for epistaxis prophylaxis in the setting of factor VII deficiency. To our knowledge we report the only case of color vision disturbance in a pediatric patient and the only case after receiving oral TXA. Soon after discontinuing oral TXA the patient's altered perception of color vision resolved. The patient was subsequently discharged home with a prescription for an alternative antifibrinolytic (aminocaproic acid) and follow-up with neuro-ophthalmology.
RESUMEN
OBJECTIVE: Ceftriaxone and cefotaxime are appealing options for the treatment of neonatal infections. Guidelines recommend cefotaxime as the cephalosporin of choice in neonates because of ceftriaxone's potential to cause hyperbilirubinemia. Unfortunately, due to cefotaxime discontinuation, providers must choose between alternative antibiotics. Clinicians at our institution adopted a protocol allowing for the utilization of cefepime and ceftriaxone for the management of neonatal sepsis. The objective of this study was to compare the incidence of hyperbilirubinemia between ceftriaxone and cefotaxime in the treatment of neonatal infections beyond the first 14 days of life. METHODS: This was a retrospective chart review of patients receiving ceftriaxone or cefotaxime for the treatment of neonatal infections. Patients were 15 to 30 days old at the time of antimicrobial administration and received at least 1 dose of ceftriaxone or cefotaxime during hospital admission. Patient characteristics and bilirubin levels were compared between ceftriaxone and cefotaxime. RESULTS: The analysis included 88 patients. There was no statistically significant difference between groups in age, gestational age, weight, and baseline total calcium and bilirubin levels. Normal baseline bilirubin levels increased to an abnormal level after antibiotic administration in 2 patients in the cefotaxime group and 1 patient in the ceftriaxone group. The median number of doses of cefotaxime and ceftriaxone were 3 and 2, respectively. CONCLUSION: Patients who received a short-term course of ceftriaxone did not have a higher likelihood of developing hyperbilirubinemia compared with those who received a short-term course of cefotaxime during their hospital stay.
RESUMEN
Rabies virus causes a fatal infection of the brain and spinal cord, accounting for approximately 59,000 deaths globally each year. Rabies postexposure prophylaxis (PEP), including both rabies immunoglobulin (RIG) and vaccination, is administered to 55,000 patients annually in the United States. With a nearly 100% case fatality rate, the optimal administration of rabies PEP cannot be understated. Updated rabies PEP guidelines issued by the World Health Organization (WHO) in 2018 recognized that local wound infiltration of RIG is the primary mechanism of protection, and the WHO now recommends only infiltration of wounds without distal intramuscular injection. We highlight potential points of failure involving wound infiltration of RIG, small-volume doses, and large-volume doses that may lead to suboptimal care and discuss implications of recent shifts toward evidence-based guidelines using wound type and RIG volumes.

INTRODUCTION: We discuss a case of massive hemoptysis in the setting of a direct-acting oral anticoagulant (DOAC) successfully managed with nebulized tranexamic acid (TXA). CASE REPORT: Per the American College of Cardiology and the American Society of Hematology, it is recommended that significant bleeding associated with a DOAC be treated with either 4-factor prothrombin complex concentrate or andexanet alfa. However, our patient was at high risk for thrombotic complications given a recent pulmonary embolism. CONCLUSION: We demonstrate that it is reasonable to trial nebulized TXA given its low cost, ease of administration, and safety profile. Additionally, this report discusses a unique dosing strategy and a previously unreported complication associated with nebulization of undiluted TXA.
