    2. Ultrasound guidance is recommended
  46. Vasopressor (cv, pharm)
    1. Norepinephrine remains the preferred Vasopressor in adults
    2. Dopamine is still surprisingly the preferred Vasopressor in children, despite three fold increased mortality in Sepsis
  47. Bag Valve Mask (er, procedure, lung)
    1. Apply a PEEP Valve to every Bag Valve Mask to prevent oxygen mixing with room air, and to keep alveoli open between breaths

    3. Exertional Heat Stroke typically presents with a young athlete, hypovolemic and diaphoretic
  10. Concussion (er, neuro)
    1. Mild Traumatic Head Injury (GCS 13-15) is the preferred term for Concussion and Minor Head Injury (and these terms are synonymous)

    2. If the last Chest Pain was >6 hours ago, a single Troponin Is sufficient
  14. Chest Tube (lung, procedure)
    1. Provide adequate sedation and anesthesia for the procedure

    1. Be alert for TEN-4 FACES (Bruising at torso, ears, neck, frenulum, angle Mandible, cheek, Eyelid, Sclera)
  16. Local Anesthesia (surgery, pharm)
    1. Lidocaine and Bupivicaine have similar times of onset (3 min), and therefore mixing these agents offers no benefit
  17. Internuclear Ophthalmoplegia (eye, neuro)
    1. On lateral gaze, Cranial Nerve 6 abducts the ipsilateral eye, and to maintain Conjugate Gaze,, a signal is passed via MLF to the contralateral eye's CN 3 to adduct (medially) in parallel
    2. With a MLF lesion, the adducting eye via CN 3 fails to adduct and in response, the abducting eye (via CN 6) demonstrates Nystagmus

    3. Varicella Vaccine may cause a vesicular rash in 5% of cases
  22. Active Shooter (prevent, abuse, work)
    1. Run-Hide-Fight may not be the best strategy in the hospital setting, where exits and hiding places are limited, and protecting vulnerable patients is also a priority
    2. Securing areas with removable locks, stocking emergency supplies, training and establishing protocols are key
  23. Synthetic Cannabinoids (psych, cd)
    1. Unpredictable with variable effects (pleasantly intoxicated vs hyperadrenergic vs Agitated Delirium vs Seizures)

    2. Consider in age >=35, if persistent or refractory Abnormal Uterine Bleeding, or known Unopposed Estrogen
  3. Angioedema (ent, derm, allergy)
    1. Angioedema management is based on whether it is histamine-mediated (e.g. Anaphylaxis) or bradykinin-mediated (e.g. hereditary, ACE Inhibitor)
    2. Bradykinin-Mediated Angioedema does not typically respond to Epinephrine, Antihistamines or Corticosteroids
    3. Management and disposition is based on edema distribution (face/lips vs anterior Tongue vs posterior Tongue vs Larynx)

    1. Combined Aspirin 81 and Plavix 75 are being used after Ischemic CVA and high risk TIA for 3 weeks (then Aspirin alone)
  9. Jailed Patient (prevent, hme)
    1. Patient must consent to blood draw or officer must have a warrant to obtain blood (fourth amendment rights), except in cases of immediate danger to patient
    2. Malingering is common, but start with a reasonable evaluation for presenting concerns (e.g. Chest Pain, Abdominal Pain)
    3. Thoroughly evaluate Trauma patients and have a low threshold for imaging (e.g. Head CT, neck CT) when indicated
