Review Meta Analysis
Influence of greater occipital nerve block on pain severity in migraine patients: A systematic review and meta-analysis.
Greater occipital nerve (GON) block may be a promising approach to treat migraine. However, the results remained controversial. We conducted a systematic review and meta-analysis to explore the efficacy of GON block in migraine patients. ⋯ Compared to control intervention, GON block intervention can significantly alleviate pain, reduce the number of headache days and medication consumption, but have no significant influence on the duration of headache per four weeks for migraine patients.

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.

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
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.
