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...

Episode 983: Head-of-Bed Position in Large Vessel Occlusion Strokes
Emergency Medical Minute
Contributor: Aaron Lessen MD Educational Pearls: Recent prospective randomized clinical trial assessed optimal head-of-bed positioning in patients with LVO 0º vs. 30º elevation Objective was to determine superiority of the two angles in stability prior to thrombectomy for LVO patients 45 patients randomized to the group with 0° head positioning and 47 patients randomized to the group with 30° head positioning Patients in the 30º group experienced worsening of NIHSS by 2 points or more Patients with head position at 0° showed score stability Hazard ratio 34.40; 95% CI,...

Episode 982: Epistaxis Management
Emergency Medical Minute
Contributor: Meghan Hurley, MD Educational Pearls: 1. Initial Assessment Start with a physical examination: Determine if the bleed is anterior or posterior. Perform a primary survey: assess airway, breathing, and circulation (ABCs). Airway compromise = intubation immediately. If the patient is stable, have them blow out any clots, then re-examine the nares. 2. Topical Medications Anesthetics: provide local anesthesia and pain relief. Lidocaine Tetracaine Vasoconstrictors: reduce bleeding. LET (Lidocaine, Epinephrine, Tetracaine) is ideal because it provides...

Episode 981: Electrical Burns
Emergency Medical Minute
Contributor: Travis Barlock, MD Educational Pearls: Quick Statistics on Electrical Burns: Electrical burns compose roughly 2 to 9% of all burns that come into emergency departments. The majority of patients who receive electrical burns are male, typically aged 20’s to 30’s, accounting for 80 to 90% of all electrical burn victims. The majority of burns are linked to occupational exposure. The upper extremities are more commonly impacted by electrical burns, accounting for 70 to 90% of entry points into the body during an exposure. What are some of the key considerations in electrical...

Episode 980: Brain Injury Guidelines (BIG)
Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: Traumatic Brain Injuries are a frequent complaint in the Emergency Department and have increased in recent years. The American Association for Surgery of Trauma (AAST) has created Brain Injury Guidelines (BIG), in an attempt to categorize brain injuries and the level of treatment they require. They are… BIG 1 Normal neuro exam Not intoxicated Not on anticoagulation or antiplatelet medications Minimal findings on head CT No fracture <4 mm bleed (subdural, epidural, intraparenchymal (max one location)) Maximum of “trace” subarachnoid...

Episode 979: Oral vs Temporal Thermometers
Emergency Medical Minute
Contributor: Taylor Lynch, MD Educational Pearls: A recent study published in a pediatric journal in April 2025 compared temporal and oral thermometers Paired temperature measurements (temporal and oral temperature within 30 minutes) were obtained from 1,412 pediatric patients 26% of patients had statistically different temporal and oral temperatures The temporal reading was always lower than the oral reading Children less than 12 years old were 2-3x more likely to actually have that statistical difference in temperatures The study also evaluated 1,000 adult patients 36% had a temporal...

Episode 977: Amyloid Therapy and Stroke-like Events
Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: The cause of Alzheimer’s disease is multifactorial, but the most widely suspected mechanism is the amyloid cascade hypothesis: Beta-amyloid proteins accumulate in the central nervous system, forming plaques that impair neuronal function. In recent years, advances have led to the development of targeted therapies with monoclonal antibodies. These drugs: Work by degrading amyloid plaques Slow the rate of cognitive decline and disease progression Have major side effects, most notably the development of amyloid-related imaging abnormalities...

Episode 976: Improvised Burr Hole in an Epidural Hematoma
Emergency Medical Minute
Contributor: Alec Coston, MD Case Report Summary: A 17-year-old female involved in a motor vehicle collision presented to a rural emergency facility via personally operated vehicle. During workup and initial CT scan, the patient began rapidly decompensating with CT revealing a 1.5cm epidural hematoma with 7mm of midline shift. The patient went from being able to walk and talk to being obtunded with a blown left pupil and unresponsive. Following intubation, the patient was being prepared for transport but potential delays required immediate emergency evacuation of the hematoma via a Burr Hole....

Educational Pearls:
Educational Pearls:
- Dental infections can be categorized into two main groups
- Infections of the gums
- Pericoronitis
- Tooth eruption leading to inflammation/irritation
- Can progress to an infection
- Requires pain control, no antibiotics
- Gingivitis
- Inflammation of the gums
- Can lead to an infection requiring antibiotics
- Abscess (gums)
- If an infection develops in the gums it can progress to an abscess
- May require drainage
- Acute necrotizing ulcerative gingivitis (ANUG) aka Trench Mouth
- Filmy, grayish discoloration of the gums with “punched out” lesions
- Extremely painful
- Can cause teeth to loosen and fall out
- Treat with IV antibiotics + admission
- Infections of the teeth
- Dental caries
- Causes sensitivity tooth enamel is worn through
- Can lead to infection
- Periapical abscess
- Abscess that extends through the root of the tooth
- Can develop up elsewhere in tooth/gums/mouth
- Causes tooth sensitivity when tapped
- Ludwig angina
- Infection of the soft tissue under the tongue
- Can compromise airway as it expands
- Treat with extensive antibiotics and debridement
- Antibiotic stewardship
- Commonly used antibiotics for dental infections
- Clindamycin
- Augmentin
- Amoxicillin
- Chlorhexidine (Peridex)
- Antiseptic and disinfectant that is helpful for gingival irritation
