Randomized Controlled Trial
Head elevation and lateral head rotation effect on facemask ventilation efficiency: Randomized crossover trials.
We performed two prospective randomized crossover trials to evaluate the effect of head elevation or lateral head rotation to facemask ventilation volume. ⋯ Head elevation increased facemask ventilation volume in normal airway patients, while lateral head rotation did not.

Case Reports
Transient vocal cord paralysis following central venous hemodialysis catheter insertion.
In this article, we present a case of recurrent laryngeal nerve palsy not caused by nerve injury but due to local anesthetic infiltration that was applied prior to central venous catheterization. A 47-year-old female patient was admitted to emergency room with fatigue and nausea and was diagnosed with acute renal failure. Right jugular venous catheterization was performed for emergency hemodialysis with Seldinger technique using middle approach. ⋯ We think temporary vocal cord palsy in our case was due to local anesthetic infiltration rather than nerve injury, since it resolved spontaneously within only hours. Expectant treatment is a good choice ensuring the patient's airway is safe. Emergency physicians should be aware of this rare complication and its right management.
