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.

Randomized Controlled Trial Comparative Study
Comparison of Xenon with LED illuminant in difficult and inhalation injury airway scenario: A randomized crossover manikin study.
The purpose of this study was to compare the effectiveness of a Xenon halogen with a light-emitting diode (LED) laryngoscope light handle in a difficult airway scenario, as well as in an inhalation injury airway scenario that combines a difficult airway and a limited view. ⋯ The LED laryngoscope light handle did not affect the recorded intubation times in the simulated difficult airway scenario, but provided significant advantages in the inhalation injury airway scenario that combines a difficult airway with a limited view caused by a sooted pharynx. We therefore hypothesize, that the LED illuminant might be beneficial in the airway management of burn patients with severe inhalation injury.

Randomized Controlled Trial Comparative Study
Comparing the success rates of standard and modified Valsalva maneuvers to terminate PSVT: A randomized controlled trial.
The study aimed to detect whether modified Valsalva maneuver (VM) is more effective than the standard VM in terminating paroxysmal supraventricular tachycardia (PSVT). ⋯ This study suggests that modified VM therapy was more effective than standard VM for terminating PSVT. The modified VM therapy also indirectly reduced the need for anti-arrhythmic medication and indirectly caused fewer side effects.
