Episode 928: Neutropenic Fever show art Episode 928: Neutropenic Fever

Emergency Medical Minute

Contributor: Taylor Lynch, MD Educational Pearls: What is neutropenic fever? Specific type of fever that is seen in cancer patients and other patients with impaired immune systems These patients are highly susceptible to infection Typically occurs 7-10 days after the last chemotherapy dose, this is when the immune system is the weakest It is useful to know the specific type of malignancy. For example, heme malignancies (ALL, AML, etc.) have more intense chemo and are at higher risk of neutropenic fever To qualify as a neutropenic fever, a patient must have one recorded temperature...

Episode 925: Table Sugar for Tongue Entrapment show art Episode 925: Table Sugar for Tongue Entrapment

Emergency Medical Minute

Contributor: Aaron Lessen, MD Educational Pearls: Pediatric case study where the child’s tongue was stuck in the opening of a hard plastic drink lid Entrapment restricts circulation which causes fluid to build and the tongue becomes more edematous with time There is a risk of ischemia with prolonged entrapment Initially tried 2% viscous lidocaine for analgesia and lubricant The ER recognized that this mucosal, edematous tongue could benefit from the trick for ostomies and rectal prolapses → table sugar! Sugar granules absorb water which decreases tissue edema This option...

Emergency Medical Minute

Contributor: Aaron Lessen, MD Educational Pearls: Hemothorax: blood in the pleural cavity, most commonly due to chest trauma Treatment: thoracostomy tube for blood drainage helps to avoid clotting, scarring, and infection A recent study looked at patients with hemothorax who either received or did not receive thoracic irrigation with saline Evaluated incidence of secondary intervention, such as video-assisted thoracoscopic surgery (VATS), for persistent hemothorax Patients who received irrigation had a slight decrease in secondary intervention frequency Multi-center study -...

Educational Pearls:

  • Humerus fractures can be characterized as proximal, midshaft, and distal fractures
  • Proximal humerus fracture is the second-most common fracture in elderly patients 
    • Primary complication is with the axillary nerve and axillary artery 
    • Vast majority are managed nonoperatively with a sling, reduction usually not indicated
    • Women comprise 70% of proximal humerus fractures, often secondary to fall with osteoporosis
  • Midshaft humerus fractures are more often managed operatively, but can be managed nonoperatively
    • Primary complication is with radial nerve, look for wrist drop!
    • May require reduction and splinting
  • Distal humerus fractures can include supracondylar fractures and involve the radius or ulna
    • One atypical is the Holstein-Lewis fracture, that can cause radial nerve damage
    • Management is varied depending on the exact type of distal humerus fracture
  • Assess degree of angulation, neurovascular status, and likelihood of compartment syndrome both before and after splint application
