Podcast 992: Fentanyl for Asthma
Emergency Medical Minute
Contributor: Alec Coston, MD Educational Pearls: BiPAP is often effective in severe asthma, but many patients struggle with mask tolerance due to intense air hunger–driven anxiety, often compounded by hypoxia. Benzodiazepines are commonly used for anxiety, but they can depress respiratory drive, making clinical improvement difficult to interpret (a lower RR may reflect sedation rather than true physiologic improvement). Low-dose fentanyl is a useful alternative when patients cannot tolerate BiPAP despite coaching. Opioids blunt the perception of dyspnea and are well established for...

Episode 990: Tramadol, or rather, Trama-don’t
Emergency Medical Minute
Contributor: Taylor Lynch, MD Educational Pearls: What is tramadol and how does it work? Tramadol is a Schedule IV opioid analgesic used for moderate pain and is often perceived as safer than other opioids due to lower abuse potential. It is a prodrug with weak direct μ-opioid receptor activity. The parent compound also inhibits serotonin and norepinephrine reuptake, giving it SSRI/SNRI-like properties. Tramadol is metabolized by CYP2D6 into O-desmethyltramadol (ODT), which has significantly stronger μ-opioid receptor agonism than the parent drug. What are the concerns with...

Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: The Case 24F brought in for anxiety. Patient is tearful, not talking, and potentially hyperventilating. History from boyfriend is that she suddenly stopped talking and started crying and it was hard to understand what she was saying. On exam, patient appears anxious and has a gaze preference for the right side and is still having difficulty speaking. Decision is made to stroke alert patient.

Episode 987: Cough Suppressants
Emergency Medical Minute
Contributor: Meghan Hurley, MD Educational Pearls: OTC Medications Dextromethorphan (DM) Most common OTC cough suppressant Minimal efficacy: Little evidence that it shortens the duration or severity of cough. Potential side effects: At recommended doses: Mild dizziness, drowsiness, GI symptoms Higher doses: Decreased consciousness, dissociative effects Guaifenesin Found in Mucinex and other severe cough/cold products Thins secretions and loosens mucus in airways No more effective than increasing oral fluid intake Prescription Medications Codeine-containing products ...

Episode 986: Lateral Canthotomy in Emergency Settings
Emergency Medical Minute
Contributor: Taylor Lynch, MD Educational Pearls: What is orbital compartment syndrome, and how is it assessed in the emergency room? Orbital compartment syndrome (OCS) is an emergent ophthalmic condition in which intraorbital pressure in the orbital compartment rises dramatically, compromising perfusion of the optic nerve and retina, leading to risk of irreversible vision loss. OCS occurs in the context of traumatic lesions with retrobulbar hemorrhage. Intraocular pressures (IOP) are measured via tonometry as a surrogate for intraorbital pressures, with emergent pathology being present when...

Episode 985: Amiodarone vs. Lidocaine
Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: How do amiodarone and lidocaine work on the heart? Amiodarone Blocks potassium channels (Class III effect). Also blocks sodium and calcium channels. Additional noncompetitive beta-blocker effects. Stabilizes cardiac tissue, slows heart rate, and suppresses both atrial and ventricular arrhythmias. Lidocaine Blocks fast sodium channels in ventricular tissue (Class Ib). Shortens the action potential in ventricular myocardium, especially in ischemic tissue. Suppresses abnormal automaticity in damaged/irritable myocardium. Which one should...

Episode 984: Fish Hooks
Emergency Medical Minute
Contributor: Megan Hurley, MD Educational Pearls: Assess first: confirm the hook isn’t near vital structures. Automatic subspecialty consult for eye involvement or proximity to carotid artery, radial artery, peritoneum, testicle, or urethra Barbed hook: cannot be pulled back through the entry without disengaging the barb Removal Techniques String-Pull: best for superficial, single-barbed hooks Depress shank and eye of hook to disengage barb and then pull string taut and jerk suddenly along the long axis Can only be used when the hook is in a body part that can be firmly secured so it...

Summary
In this episode of Mental Health Monthly, Dr. Travis Barlock hosts Dr. Andrew White to discuss the elements of mania that may be encountered in the emergency department. The discussion includes a helpful mnemonic to assess mania, work-up and treatment in the ED, underlying causes of mania, mental health holds, inpatient treatment, and the role of sleep in mania.
Educational Pearls
-
Initial assessment of suspected mania can be done via DIGFAST:
-
Distractibility - Individual that is unable to carry a linear, goal-directed conversation
-
Impulsivity - Executive functioning is impaired and patients are unable to control their behaviors
-
Grandiosity - Elevated mood and sense of self to delusions of grandeur
-
Flight of ideas - Usually described as racing thoughts
-
Agitation - Increase in psychomotor activity; start several projects of which they have little previous knowledge
-
Sleep decrease - Typically, manic episodes start with insomnia and can devolve into multiday sleeplessness
-
Talkativeness - More talkative than usual with pressured speech and a tangential thought process
-
Interviewing patients requires an understanding of mood-based mania vs. psychosis-based mania
-
An individual with mood-based mania will more likely be restless, whereas a patient with psychosis-based mania will be more relaxed from a psychomotor standpoint
-
Treatment of manic patients in the ED includes the use of antipsychotics to manage acute symptomatology
-
Management can be informed and directed by the patient’s history i.e. known medications that have worked for the patient
-
ED management of manic patients involves a work-up for a broad differential including agitated delirium, substance-induced mania, metabolic disorders, and autoimmune diseases.
-
Some individuals experience manic episodes from marijuana and other illicit substances
-
Antidepressants used in bipolar patients for suspected depression may induce mania
-
Important to avoid using antidepressants as first-line therapy
-
Mental health holds can be beneficial in patients with grave disabilities from mania
-
Oftentimes, undertreatment of manic episodes leads to re-hospitalization
-
Inpatient treatment:
-
Environment is important - ensure that patients get solo rooms if possible to minimize stimulation
-
Antipsychotics, including risperidone and olanzapine, with or without a benzodiazepine, are useful for short-term agitation
-
Long-term treatment involves coupled pharmacological treatments with non-pharmacological treatments
-
Sleep
-
Fractured sleep is one of the earliest warning signs that someone has an imminent manic episode
-
Poor sleep can be an inciting factor for mania, which then turns into a cycle that further propagates a patient’s manic episode
