August Intro: The Dilaudid® Debacle

Hydromorphone produces more prominent euphoria than morphine in some studies, but whether that translates into greater ED abuse risk is unsettled. When opioids are needed for acute pain, the real bedside question is usually route and sequencing: start oral when possible, use IV selectively, and avoid reflexive repeat IV dosing. Hydromorphone Versus Morphine in Acute Pain Higher likability signal: Hydromorphone has shown higher subjective “likability” and “feeling high” scores than morphine in healthy volunteers, a pharmacologic distinction that keeps surfacing in bedside opioid choice. Abuse liability uncertainty: More likable does not automatically mean more abuse-prone; the link between positive subjective effects and real-world misuse remains uncertain, and that distinction is worth hearing in the episode. Migraine return-visit data: In ED migraine patients randomized to hydromorphone 1 mg versus prochlorperazine 10 mg plus diphenhydramine 25 mg IV, medication likability was not associated with higher return visits. Pain relief versus euphoria: Higher likability scores may track with better analgesia rather than a simple drug “high,” which complicates the common shorthand that hydromorphone is just “hospital heroin.”},{ Practical Opioid Route Strategy Oral first approach: When patients can take medications enterally, starting with PO or SL opioids may control pain adequately and can make discharge easier by avoiding a second round of IV analgesia. Morphine conversion pearl: Oral morphine is roughly 3:1 compared with IV dosing, with a typical starting PO dose around 15 to 20 mg when escalation beyond non-opioids is needed. Sublingual route advantages: Sublingual morphine and oxycodone can act faster than standard oral dosing and last longer than IV dosing, a route choice with useful bedside nuance we get into in the chapter. Selective IV fentanyl use: IV fentanyl is best reserved for severe acute pain, with a plan to transition after one or two doses to SL, PO, or another longer-acting option. Hydromorphone practice split: Some clinicians have stopped using hydromorphone entirely, while others still value its analgesic effect; the divide often reflects concerns about euphoria, nursing preferences, and repeat dosing patterns.

Updated Chest Pain Pathway: Incorporating High-Sensitivity Troponin

High-sensitivity troponin changes ED chest pain evaluation because it detects myocardial injury far more often than older assays, and an elevated value is not the same as acute coronary syndrome. Safe use depends on assay-specific cutoffs, timed delta testing, and ECG-guided clinical context. High-Sensitivity Troponin in Chest Pain Assay-specific interpretation matters: High-sensitivity troponin I is not interchangeable with conventional troponin or with other manufacturers’ assays, so reference ranges, units, and delta rules must match the exact test your lab uses. Elevation is not ACS: Most elevated hs-TnI results are not occlusive MI; roughly 80% reflect myocardial injury from causes like renal dysfunction, heart failure, systemic illness, or severe hypertension. Timed delta drives disposition: A single hs-TnI rarely settles the question in intermediate results because the pathway depends on repeat testing at defined intervals and whether the value is rising, flat, or falling. We walk through that timing logic in the episode. ECG plus troponin framing: A nonischemic ECG with a normal hs-TnI supports discharge, while a clearly elevated hs-TnI generally warrants admission for further workup even though it does not by itself diagnose AMI. Sex-specific cutoffs matter: Intermediate hs-TnI ranges are sex-specific, and using the correct female thresholds can identify myocardial infarction that older pathways were more likely to miss. Order it when it matters: Because hs-TnI is much more likely to return abnormal than prior-generation troponin, indiscriminate testing can increase admissions without helping care unless the result will change management or disposition.

Lit Matters 1: GU swab vs. Urine for STI Detection

Vaginal NAAT swabs are more sensitive than urine for detecting chlamydia, gonorrhea, and trichomonas in women. CDC guidance already prefers vaginal swabs, but the real emergency-department question is whether a modest diagnostic gain justifies changing workflow, specimen collection, and screening practice. Swab Versus Urine for STI NAATs Sensitivity advantage of swabs: Vaginal swabs outperformed urine across all three infections, with the clearest gap in chlamydia detection at 94.1% versus 86.9%, reinforcing why swabs remain the preferred female specimen. CDC specimen preference: CDC guidance favors vaginal swabs as the primary collection method for women, aligning practice with the best-performing FDA-cleared NAAT specimen type rather than defaulting to urine. Clinical size of the gap: The difference is real but modest: gonorrhea sensitivity was 96.5% for swabs versus 90.7% for urine, while trichomonas showed a smaller, non-significant separation. Workflow versus yield: Patient-obtained vaginal swabs may improve flow by allowing collection right after registration, but whether that gain is enough to fully replace urine testing is the practical tension we get into in the episode. Specimen collection mechanics: Urine STI testing is only as good as the specimen quality, and a clean-catch sample is the wrong collection method for NAAT detection, creating an easy bedside source of false reassurance. ED practice question: This meta-analysis answers assay sensitivity, not how often symptomatic ED patients are truly missed or whether every screening encounter warrants an invasive exam; that distinction is worth hearing in the chapter.

Fournier's Gangrene

Fournier’s gangrene is a rare but time-critical necrotizing soft tissue infection of the perineum that often presents subtly before declaring itself as sepsis or shock. The key emergency medicine move is recognizing that this is fascial spread, not simple cellulitis, and moving early on resuscitation, broad-spectrum antibiotics, and surgery. Recognition and Diagnosis Fascial plane infection: Fournier’s gangrene is not just cellulitis; it is a polymicrobial necrotizing infection tracking through perineal fascial planes, which is why early skin findings can look deceptively mild. Typical presenting complaints: Swelling, pain, and erythema are the most common early complaints, while pain out of proportion should raise concern even before bullae, necrosis, or crepitus appear. Occult sepsis source: Sepsis without a source should prompt a groin and perineal exam, because Fournier’s can present subacutely over days to weeks before hypotension makes the diagnosis obvious. That bedside search pattern is worth hearing in the episode. Risk factor pattern: Older age, diabetes, obesity, immunocompromise, alcohol or injection drug use, and male sex all shift the pretest probability upward when perineal symptoms seem otherwise routine. Limits of testing: No single lab test rules Fournier’s in or out, and LRINEC is not reliable enough for exclusion; even low scores have occurred in necrotizing soft tissue infection. Imaging clues: CT with IV contrast is the first-choice study when imaging is needed, while POCUS may show thickened tissue, cobblestoning, and subcutaneous gas with a classic snow globe appearance. Sources and Initial Management Common anatomic sources: The infection most often starts from a GI source, with GU sources next and cutaneous sources least common, so perianal, rectal, and urologic complaints deserve a wider lens. Straightforward treatment priorities: Management hinges on three moves: hemodynamic resuscitation, broad-spectrum antimicrobials, and operative debridement, with delay to the OR driving tissue loss and mortality. Early surgical involvement: Call surgery as soon as Fournier’s is on the table, because they can mobilize the OR, guide imaging decisions, and coordinate the specialty support these patients often need. Headline antibiotic approach: Empiric therapy needs broad polymicrobial coverage, typically with piperacillin-tazobactam or meropenem plus vancomycin and clindamycin, with a few situational additions we get into in the episode. Transfer threshold mindset: Err early toward transfer when local operative or reconstructive resources are limited, since definitive management often requires a center that can support complex debridement and critical care.

Super Drugs for Super Bugs

ESBL and carbapenemase-producing gram negatives now show up in everyday emergency care, especially in nursing-home residents, recently hospitalized patients, and those with devices. Empiric choices for urosepsis and resistant Pseudomonas hinge on exposure history, local antibiograms, and knowing when a positive culture does not need treatment. ESBL and Carbapenemase Infections ESBL resistance mechanism: Extended-spectrum beta-lactamases hydrolyze most cephalosporins and often travel on plasmids, which helps resistance spread quickly across Enterobacteriaceae. High-risk exposure pattern: Recent hospitalization or ICU stay, long-term care residence, foreign bodies, prior antibiotics, hemodialysis, and ventilation sharply raise the pretest probability of ESBL infection. Empiric urosepsis choice: Carbapenems remain the best-studied first-line agents for ESBL urosepsis, while piperacillin-tazobactam is not a reliable fallback even when the lab reports susceptibility. Collateral resistance problem: ESBL isolates are frequently co-resistant to fluoroquinolones and TMP-SMX, making familiar oral step-down options far less dependable at the bedside. Carbapenemase escalation: Carbapenemases knock out even carbapenems and can leave only agents like ceftazidime-avibactam or meropenem-vaborbactam, with combination nuances we get into in the episode. Positive culture context: Not every culture growing a multidrug-resistant organism needs admission or treatment; a chronically colonized Foley urine is often positive without true infection. Resistant Pseudomonas and Outpatient Options Pseudomonas risk profile: Sepsis with skilled-nursing exposure, prior surgery, prolonged antibiotic courses, neutropenia, burns, and long lengths of stay should push resistant Pseudomonas higher on the list. Antipseudomonal drug reality: Cefepime, ceftazidime, piperacillin-tazobactam, aztreonam, ciprofloxacin, aminoglycosides, and meropenem all face meaningful resistance pressure, so no single class is fail-safe. Combination therapy rationale: Using two antipseudomonal agents from different classes can improve the odds that at least one is active when multidrug resistance is a real concern. We walk through when that matters on the show. Local epidemiology matters: Resistance patterns vary by hospital and unit, so the local antibiogram and early infectious-disease input often matter more than any generic national preference list. Selective outpatient management: Some ESBL urinary infections can be managed outside the hospital, and some bacteriuria should be left alone entirely if the patient lacks symptoms of true infection. Oral cystitis options: Nitrofurantoin and fosfomycin remain useful oral options for ESBL cystitis, but nitrofurantoin is not a pyelonephritis drug and oral strategies have important caveats in the chapter.

Lit Matters 2: Once Again, VL Outperforms DL

Video laryngoscopy improves first-pass endotracheal intubation success in critically ill adults in the ED and ICU. In a large randomized trial, VL beat direct laryngoscopy by a clinically meaningful margin without reducing severe peri-intubation complications. Video Versus Direct Laryngoscopy First-pass success advantage: VL achieved first-pass tracheal intubation in 85% of critically ill adults versus 70.8% with DL, a result strong enough that the trial was stopped early. Glottic view superiority: Inadequate laryngeal view was far less common with VL, occurring on 3.7% of first attempts versus 17.3% with DL, which helps explain the success gap. Complication rate reality: Severe complications were essentially unchanged despite better first-pass success, with major peri-intubation events around 21% in both groups. Operator experience effect: The benefit of VL narrowed as intubators became more experienced, with the edge shrinking to about 5% after more than 100 prior tubes. We get into what that means for seasoned DL users in the episode. Practical airway takeaway: Most study intubations were done by residents or fellows with modest prior experience, making VL the more reliable default for the clinicians who perform emergency airways less often now.

Attitude is Everything

Clinician attitude shapes wellness, team dynamics, and patient trust in the emergency department. A positive mindset is not personality fluff; it is a practiced, authentic performance skill that improves resilience, communication, and the tone of an entire shift. Attitude in Emergency Medicine Chosen response mindset: Attitude is framed as a daily choice in the face of fatigue, stress, and bad outcomes; the controllable variable is not the shift but your response to it. Authenticity over performance: A good attitude has to come from a genuine reason rather than forced positivity, because patients and coworkers quickly detect anything that feels fake. Consistency builds routine: Positive attitude behaves like any other skill: repeated effort turns it into habit, and that momentum often carries into more focused and productive work. Realistic resilience frame: This is not about feeling 10 out of 10; sometimes success is simply moving from a 3 to a 5 and staying usable under pressure. We get into that practical frame in the episode. Fuel and reset cues: Mindset needs reinforcement from concrete cues such as a meaningful photo, quote, or brief walk, with simple reset tactics that are easy to apply mid-shift. Patient trust signals: Empathy is operationalized through eye-level positioning, active listening, and paraphrasing, while standing at the door or checking a phone quietly undermines trust. How Attitude Affects the ED Attending sets the tone: The attending physician often establishes the emotional climate of the department, and colleagues commonly link a consistently positive presence with a good shift. Reciprocal team effect: Attitude spreads through the department like a mirror effect; one person's mood can noticeably raise or drag the performance and interactions of everyone nearby. Grace and perspective: A realistic attitude includes recognizing that coworkers may be carrying unseen burdens, and that patients often experience this visit as a major life event. Relationship and compliance impact: Positive attitude strengthens rapport with patients and coworkers, improving trust and buy-in in ways that matter clinically even before any treatment plan is discussed.

Lit Matters 3: Emergency Severity Index Mis-Triage Rates

Emergency Severity Index triage misses matter most when low-acuity labels hide critical illness. ESI is widely used in US emergency departments, but large-scale data show mistriage is common, driven mostly by overtriage while a smaller undertriaged group carries the real safety signal. Emergency Severity Index Mis-Triage Large cohort signal: A 5.3 million–encounter health system analysis found mistriage in 32.2% of ED visits, giving this paper unusual weight when thinking about how ESI performs in real practice. Undertriage safety problem: Undertriage was less common at 3.3%, but it is the clinically dangerous miss because patients labeled ESI III to V can deteriorate while still waiting for reassessment. Overtriage expected tradeoff: Overtriage accounted for 28.9% of encounters, reinforcing the core triage principle that false positives are often acceptable if the system reliably captures patients at risk of crashing. ESI III black box: Most undertriaged encounters were ESI III patients who likely belonged in ESI II, underscoring how the middle of the scale becomes a catch-all for uncertain acuity. Critical illness misses: Among patients who ultimately needed a level 1 intervention, 60.9% were undertriaged, a striking reminder that even the sickest patients are not always obvious at first pass. We get into why that number does and does not mean ESI is failing in the episode. Operational fix options: Nurse judgment remains central, but crowded departments with heavy boarding may benefit from physician-in-triage models when overtriage is overwhelming room placement and reassessment capacity.

Eli's Story: The Fentanyl Crisis

Illicit fentanyl contamination now drives much of the U.S. overdose crisis, often through counterfeit pills, stimulants, and other non-opioid drugs. A lethal dose can be just 2 mg, and bedside harm reduction starts with clear patient education, naloxone access, and fentanyl test strips. Fentanyl Poisoning and Harm Reduction Counterfeit pill risk: Fentanyl now appears in counterfeit benzodiazepines and opioid tablets, as well as cocaine and methamphetamine, so many poisoned patients never intended to take an opioid. Potency and lethality: Fentanyl is about 100 times more potent than morphine, and lethal contamination became common as the illicit market shifted after 2013. Overdose death burden: Synthetic opioids were involved in 67% of more than 107,000 U.S. overdose deaths in a single year, underscoring why this is now core clinical counseling, not a niche topic. Test strip performance: Fentanyl test strips have roughly 92% to 96% sensitivity and give patients actionable information before use. We walk through the practical counseling angle in the episode. Incidental exposure myth: Brief dermal fentanyl exposure is unlikely to cause toxicity; removing visible residue and focusing on airway, breathing, and CPR matters more than panic. Stage-based clinician response: Harm reduction starts with meeting patients where they are in addiction readiness, then using every encounter to educate, equip, and keep them alive until treatment is possible. Eli's Story and Community Response Unintentional fentanyl death: Eli's death illustrates a central reality of this crisis: many young people ingest fentanyl unknowingly and do not intend self-harm or overdose. Kratom plus fentanyl: The coroner identified kratom and fentanyl, a reminder that legal or familiar substances do not exclude dangerous adulteration from the broader drug supply. Rainbow fentanyl targeting: Colorful pills and powders marketed as rainbow fentanyl are designed to appeal to younger users, adding a prevention challenge for families, schools, and clinicians. Patient education script: A simple question like asking whether someone has heard of counterfeit pills can open the door to counseling; one cited estimate is that about 20% contain fentanyl. BirdieLight resources: BirdieLight focuses fentanyl education on ages 14 to 25 while also supporting clinicians, educators, and families with curricula and test-strip access. We get into those community tools in the chapter.
