    expectoration/ coughing of blood originating from tracheobronchial tree


    Bronchial arteries (90%): under systemic circulatory pressure to supply supporting structures of the lung → heavier bleeding

    Pulmonary arteries (5%): under low pressure to supply alveoli → milder bleeding

    Nonbronchial arteries (5%): intercostal arteries, coronary arteries, thoracic/ upper/ inferior phrenic arteries


    Mild: 300mL-1L/ 24hr

    Mortality: 38% for massive (>500mL/ 24hr) vs 4.5% for nonmassive

    Etiology (in adults):

    Infectious (most common):


    PNA (necrotizing, lung abscess)






    Primary lung cancer vs metastatic disease




    PE/ infarction

    Bronchopleural fistula



    Mitral stenosis

    Tricuspid endocarditis



    Goodpasture Syndrome


    Vasculitis (Wegener’s, HSP, Behcet)

    2007 Infectious Diseases Society of America/American Thoracic Society Criteria for Defining Severe Community-acquired Pneumonia

    Validated definition includes either one major criterion or three or more minor criteria

    * Minor criteria

    * Respiratory rate > 30 breaths/min PaO2/FIO2 ratio 20 mg/dl)

    * Leukopenia* (white blood cell count , 4,000 cells/ml)

    * Thrombocytopenia (platelet count , 100,000/ml)

    * Hypothermia (core temperature , 368 C) Hypotension requiring aggressive fluid

    * resuscitation

    * Major criteria

    * Septic shock with need for vasopressors

    * Respiratory failure requiring mechanical ventilation

    Episode 173.0 – Blunt Neck Trauma

    Episode 173.0 – Blunt Neck Trauma

    We go into one of the more complex injuries – blunt neck trauma.

    Show Notes


    Blunt neck trauma comprises 5% of all neck trauma

    Mortality due to loss of airway more so than hemorrhage


    MVCs with cervical hyperextension, flexion, rotation during rapid deceleration, direct impact  

    Strangulation: hanging, choking, clothesline injury (see section on strangulation in this chapter)

    Direct blows: assault, sports, falls

    Initial Management/Primary Survey


    Evaluate for airway distress (stridor, hoarseness, dysphonia, dyspnea) or impending airway compromise

    Early aggressive airway control: low threshold for intubation if unconscious patient, evidence of airway compromise including voice change, dyspnea, neurological changes, or pulmonary edema

    Assume a difficult airway 

    * Breathing

    Supplemental oxygen

    Assess for bilateral breath sounds 

    Can use bedside US to evaluate for pneumothorax or hemothorax

    * Circulation

    Assess for open wounds, bleeding, hemorrhage 

    IV access

    * Disability

    Maintain C-spine immobilization 

    Calculate GCS

    Look for seatbelt sign

    Secondary Survey

    Evaluate for specific signs of vascular, laryngotracheal, pharyngoesophageal, and cervical spinal injuries with inspection, palpation, and auscultation

    Perform extremely thorough exam to evaluate for any concomitant injuries (e.g. stab wounds, gunshot wounds, intoxications/ ingestions, etc.)

    Types of Injuries

    Vascular injury


    Carotid arteries (internal, external, common carotid) and vertebral arteries injured

    Mortality rate ~60% for symptomatic blunt cerebral vascular injury


    Hyperextension and lateral rotation of the neck, direct blunt force, strangulation, seat belt injuries, and chiropractic manipulation

    Morbidity due to intimal dissections, thromboses, pseudoaneurysms, fistulas, and transections

    Clinical Features

    Most patients are asymptomatic and do not develop focal neurological deficits for days

    if Horner’s syndrome, suspect disruption of thoracic sympathetic chain (wraps around carotid artery)

    specific screening criteria are used to detect blunt cerebrovascular injury in asymptomatic patients (see below)

    Episode 172.0 – Ankle Sprains

    Episode 172.0 – Ankle Sprains

    We dissect one of the most common injuries we see in the ER -- ankle sprains

    Tags: Orthopedics

    Show Notes


    * Among most common injuries evaluated in ED

    * A sprain is an injury to 1 or more ligaments about the ankle joint

    * Highest rate among teenagers and young adults

    * Higher incidence among women than men

    * Almost a half are sustained during sports

    * Greatest risk factor is a history of prior ankle sprain


    * Bone: Distal tibia and fibula over the talus → constitutes the ankle mortise

    * Aside from malleoli, ligament complexes hold joint together

    * Medial deltoid ligament

    * Lateral ligament complex

    * Anterior talofibular ligament

    * Most commonly injured

    * Weakest

    * 85% of all ankle sprains 

    * Posterior talofibular ligament

    * Calcaneofibular ligament

    * Syndesmosis

    Mechanism of Injury

    * Lateral ankle sprains 

    * Most common among athletes

    * ATFL most commonly injured

    * Combined with CFL in 20% of injuries

    * 2/2 inversion injuries

    * Medial ankle sprains

    * Less common than lateral because ligaments stronger and mechanism less frequent

    * More likely to suffer avulsion fracture of medial malleolus than injure medial ligament

    * 2/2 eversion +/- forced external rotation

    * Typically landing on pronated foot -> external rotation

    * High Ankle sprains

    * Syndesmotic injury

    * More common in collision sports (football, soccer, etc)

    * Grade I

    * Mild

    * Stretch without “macroscopic” tearing

    * Minimal swelling / tenderness

    * No instability

    * No disability associated with injury

    *     Grade II

    * Moderate

    * Partial tear of ligament

    * Moderate swelling / tenderness

    * Some instability and loss of ROM

    * Difficulty ambulating / bearing weight

    *     Grade III

    * Severe

    * Complete rupture of ligaments

    * Extensive swelling / ecchymosis / tenderness

    * Mechanical instability on exam

    * Inability to bear weight


    *     Beyond visual inspection for swelling, ecchymoses, abrasions, or lacerations

    * Palpation 

    * Pain when palpating ligament is poorly specific but may indicate injury to structure

Not just for medical students!

I am in emergency room nurse and this has definitely helped my practice and ability to communicate with residents and attending MDs about patient presentations and interventions.

Sher Ali Khan ,

Quick, efficient and practical review

Very ice Job. I am intense medicine and I enjoy listening to it for my Hospital based practice in residency

Kristy5150 ,

Free and Fabulous!

I absolutely love this short free podcast. It is easy listening and chock full of good up-to-date information. I’ve been following Swami for quite some time and he has a way of making emergency medicine exciting even for this old APC.
