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
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.

Ultrasound is an ideal modality in the emergency department (ED) to assess for pneumothorax given its rapid availability, portability, and repeatability to assess clinical status changes. Certain patient populations and clinical circumstances may present challenges to the performance of this examination. In this article, we review patterns of the presence or absence of lung sliding in the commonly utilized sonographic modes in the ED setting. We also describe a novel technique to evaluate lung sliding using tissue Doppler.
