Randomized Controlled Trial
Does the novel lateral trauma position cause more motion in an unstable cervical spine injury than the logroll maneuver?
Prehospital personnel who lack advanced airway management training must rely on basic techniques when transporting unconscious trauma patients. The supine position is associated with a loss of airway patency when compared to lateral recumbent positions. Thus, an inherent conflict exists between securing an open airway using the recovery position and maintaining spinal immobilization in the supine position. The lateral trauma position is a novel technique that aims to combine airway management with spinal precautions. The objective of this study was to compare the spinal motion allowed by the novel lateral trauma position and the well-established log-roll maneuver. ⋯ In this cadaver study, the novel lateral trauma position and the well-established log-roll maneuver resulted in comparable amounts of motion in an unstable cervical spine injury model. We suggest that the lateral trauma position may be considered for unconscious non-intubated trauma patients.

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.

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.
