Author: Chris Holmes M.D. Educational Pearls: Mechanism of injury involves hyperextension/hyperflexion Pathophysiology: inside of the arteries in the neck becomes disrupted, similar to a dissection. This is thrombogenic and leads to cerebral infarction Neurologic deficit is common. Other risk factors include facial fracture and cervical-spine fracture. Treat with anticoagulation - aspirin or other antiplatelet agents are appropriate. Increase clinical suspicion when patient presents with neurolo...

Author: Aaron Lessen M.D. Educational Pearls: Regularly a patient’s creatinine level is an important factor in determining whether a patient will receive IV contrast with a CT because it is thought that contrast can harm the kidneys and could worsen underlying kidney disease. A recent retrospective study compared the rates of worsening kidney problems between patients who received a CT scan with contrast, a CT without contrast, and no CT. The study even included patients with creatinines of up t...

Author: Peter Bakes Educational Pearls: The Neuromuscular Junction (NMJ) is a neuronal synapse in skeletal muscle mediated by nicotinic acetylcholine receptors. Paralytic agents, commonly used in the ED for intubation, include succinylcholine and rocuronium/vecuronium. Succinylcholine is a depolarizing paralytic while rocuronium is a non-depolarizing agent. A newly developed reversing agent, sugammadex, can be used to counter the effects of curonium based paralytics. This is especially helpful d...
