Podcast 999: Right vs Left Internal Jugular Access
Emergency Medical Minute
Contributor: Travis Barlock, MD Educational Pearls: What is an internal jugular catheter (IJ) and when do we use it? IJs are catheters that can be placed in either the left or the right internal jugular vein to provide central venous catheter (CVC) access. CVCs can be placed in other locations other than the internal jugular vein (i.e. subclavian vein or femoral veins). IJs are used when the patient may require long-term venous access or have to receive hyperosmolar solutions (such as solutions with high glucose content for parenteral nutrition); solutions with extreme pHs (<5 or >9);...

Podcast 998: Delayed Intubation After an Overdose
Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: How long do we need to watch patients with a presumed overdose who were treated with naloxone in the field? A 2025 study in the Annals of Emergency Medicine took a look at this question Methods Prospective, multi-institutional cohort study Included ED patients with suspected acute opioid overdose with biologic testing to confirm substances. This paper performed a secondary analysis evaluating the risk of “delayed intubation,” defined as intubation occurring >4 hours after ED arrival. Results 1,591 patients with presumed opioid...

Podcast 997: D-Dimer
Emergency Medical Minute
Contributor: Travis Barlock, MD Educational Pearls: D-dimer: fibrin degradation product used to evaluate for clot formation and breakdown Threshold: <500ng/mL rules out venous thromboembolism in low risk patients Elevated D-dimer indicates recent or ongoing intravascular coagulation and fibrinolysis YEARS score: algorithm to assess PE risk using three clinical criteria Criteria: signs of DVT, hemoptysis, and PE as the most likely diagnosis YEARS score of 0 with D-dimer <1000 ng/mL: PE can be ruled out YEARS score of ≥1 with D-dimer <500 ng/mL: PE can be ruled out A study found...

Podcast 996: Melatonin
Emergency Medical Minute
Contributor: Taylor Lynch MD Educational Pearls: Melatonin is an endogenous hormone released primarily by the pineal gland Also released by extrapineal regions in the retina, the GI tract, and some immune cells Peak secretion occurs at night and is suppressed during the day Secretion and production decrease with age Older patients experience the greatest improvement in sleep latency and sleep quality Mechanism of action in the suprachiasmatic nucleus of the hypothalamus MT1 receptor Reduces normal firing MT2 receptor Shifts the circadian rhythm FDA approved for insomnia ...

Episode 995: UTI Diagnosis
Emergency Medical Minute
Contributor: Travis Barlock, MD Educational Pearls: Foul-smelling urine and cloudy urine are commonly misinterpreted as indicators of a UTI. However, these findings alone are not diagnostic. Criteria for UTI: Presence of localized urinary symptoms: Suprapubic pain Dysuria Hesitancy Urgency Urinalysis with WBC > 10 Urine culture with > 100,000 CFU/mL Colonization differs from infection - many patients harbor asymptomatic bacteria but do not have a true infection. Consequences of overtreatment One review showed 45% of patients treated with antibiotics for a presumed UTI...

Podcast 994: Biphasic Anaphylaxis
Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: What is anaphylaxis and what are its treatments? Anaphylaxis is a broad term for potentially life threatening allergic reactions that can progress to cardiovascular collapse (anaphylactic shock). It is triggered by IgE and antigen cross-linking on mast cells to induce degranulation and the release of histamines, which can cause diffuse vasodilation and respiratory involvement with end-organ hypoperfusion. First line treatment is the immediate administration of epinephrine at 0.01 mg/kg (max dose for pediatrics is 0.3 mg and for...

Podcast 993: Personalized Gene Editing Therapy
Emergency Medical Minute
Contributor: Alec Coston, MD Educational Pearls: Disclaimer: this has nothing to do with the ER but is too cool to not talk about. Condition: Carbamoyl phosphate synthetase 1 (CPS1) deficiency Rare inborn error of metabolism Inability to properly break down ammonia Leads to severe hyperammonemia and hepatic encephalopathy Natural history: Without treatment, typically fatal within the first few weeks of life Even with current standard treatments, life expectancy is often limited to ~5–6 years Breakthrough treatment: A team of researchers at the Children’s Hospital of...

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 991: BRASH
Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls BRASH Syndrome: Bradycardia Renal Failure AV Nodal Blockade Shock Hyperkalemia Clinical Features: Profound bradycardia and shock in patients on AV nodal blockers: Commonly, Beta Blockers or Calcium Channel Blockers Etiology: Caused by an inciting kidney injury: Common triggers include precipitating illness, dehydration, or medications Results in hyperkalemia The enhanced effect of the combination of AV nodal blockade and hyperkalemia leads to a more profound presentation of shock. ...

The Core features of trauma-informed care include:
- Patient empowerment, choice and collaboration. This means educating patients and allowing patients to make choices about their care when possible. Collaboration helps to level the power differential between patients and providers through shared decision making.
- Safety and sensitivity: Developing health care settings and activities that ensure patients’ physical and emotional safety taking into account their diverse backgrounds of gender, sexuality, race, culture, and ethnicity
- Trustworthiness and transparency: Creating clear expectations with patients about what proposed treatments entail, who will provide services, and how care will be provided.
