Just the facts: brachial plexus blocks for upper extremity injuries in the emergency department.
Ultrasound-guided nerve blocks (UGNBs) are becoming a more common method for pain control in the emergency department. Specifically, brachial plexus blocks have shown promise for acute upper extremity injuries as well as an alternative to procedural sedation for glenohumeral reductions. Unfortunately, there is minimal discussion in the EM literature regarding phrenic nerve paralysis (a well-known complication from brachial plexus blocks). ⋯ The focus on patient safety is paramount, and those with preexisting respiratory conditions, extremes of age or weight, spinal deformities, previous neck injuries, and anatomical variations are at greater risk. We put forth different block strategies for risk mitigation, including patient selection, volume and type of anesthetic, block location, postprocedural monitoring, and specific discharge instructions. Understanding the benefits and risks of UGNBs is critical for emergency physicians to provide effective pain control while ensuring optimal patient safety.

Phenobarbital has been used in the emergency department (ED) as both a primary and adjunctive medication for alcohol withdrawal, but previous studies evaluating its impact on patient outcomes are limited by heterogenous symptom severity. ⋯ Patients who received phenobarbital for moderate alcohol withdrawal were more likely to be admitted to the hospital, but there was no difference in admission level of care when compared with patients who received benzodiazepines alone. Patients who received phenobarbital were provided greater lorazepam equivalents in the ED.

Metformin is a biguanide hyperglycemic agent used to manage non-insulin-dependent diabetes mellitus. Adverse reactions include mainly mild gastrointestinal adverse effects, but severe complications, such as metformin-associated lactic acidosis (MALA) can occur. Metformin is excreted renally and, therefore, not recommended in patients with renal impairment. The reported incidence of MALA is 3 cases per 100,000 patient-years. ⋯ A 79-year-old woman with a complex medical history, including end-stage renal disease on dialysis and type 2 diabetes, presented to the emergency department (ED) for altered mental status. Prior to arrival, she was found to be hypoglycemic. Her laboratory results were significant for creatinine of 6.56 mg/dL and an anion gap of 52 mmol/L. The venous blood gas revealed a venous pH of 6.857 [reference range (7.32-7.43)], pCO2 of 15.9 mm Hg (40.6-60 mm Hg), HCO3 of 2.7 mmol/L (21-30 mmol/L), lactate of 27 mmol/L (0.5-2 mmol/L), and ammonia of 233 µmol/L. The patient was dialyzed emergently in the ED; repeat laboratory test results showed blood urea nitrogen of 10 mg/dL, creatinine of 1.65 mg/dL, carbon dioxide of 26 mmol/L, and anion gap of 13 mmol/L. The repeat ammonia was 16 µmol/L. The patient's metabolic encephalopathy resolved, and she was discharged home on hospital day 3. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: MALA has a high mortality rate (36%). Laboratory markers have not been found to be a reliable predictor of mortality. Sodium bicarbonate is controversial, but a pH < 7.15 indicates consideration of its use. A pH < 7.1 and a lactate level > 20 mmol/L indicate the need for emergent hemodialysis. Prompt recognition and management in the ED with early hemodialysis can result in good patient outcomes, with a return to their baseline function despite severe laboratory findings.

Academic medical centers must balance caring for patients in their community with their role as referral centers for more profitable tertiary quaternary (T/Q) care. Hospital medicine services, which admit patients largely from the emergency department, often have the lowest proportion of T/Q care and may thus be under pressure to demonstrate their value to the health system. Looking at the 5771 patients that were discharged from our hospital medicine service between 2021 and 2022, we found that three quarters (74.6%) of patients had at least one prior outpatient encounter at our institution, and that more than a third (36.1%) were established patients in departments of strategic importance to our institution. Our study provides a framework for academic hospital medicine services looking to assess their patient population's connection with the broader health system and suggests that our hospital medicine service provides inpatient care to a population critical to the role of the institution in our community both locally and regionally.

Are emergency departments leader identity workspaces? A qualitative study of emergency physicians.
Emergency medicine is a discipline with complex leadership demands, which are experienced by junior and senior emergency physicians alike. In this environment, emergency physicians can struggle to work out what it means to be a leader and develop professional identities as leaders, necessitating a leader identity workspace. The aim of the present study is to explore whether emergency physicians view their work environment as leader identity workspaces. ⋯ Our results suggest that neither EDs nor hospitals more generally exhibit the properties of, or are experienced by emergency physicians, as leader identity workspaces.
