Randomized Controlled Trial Comparative Study
A randomized open-label study of sodium valproate vs sumatriptan and metoclopramide for prolonged migraine headache.
The objective of this study is to compare the efficacy and tolerability of intravenous valproic acid (iVPA) with intramuscular metoclopramide + subcutaneous (SQ) sumatriptan for prolonged acute migraine. ⋯ Treatment with iVPA was more effective than metoclopramide + SQ sumatriptan during the first 2 hours in patients with a prolonged migraine.

Randomized Controlled Trial Comparative Study
A comparison of longitudinal and transverse approaches to ultrasound-guided axillary vein cannulation.
The axillary vein is an easily accessible vessel that can be used for ultrasound-guided central vascular access and offers an alternative to the internal jugular and subclavian veins. The objective of this study was to identify which transducer orientation, longitudinal or transverse, is better for imaging the axillary vein with ultrasound. ⋯ The longitudinal method of visualizing the axillary vein during ultrasound-guided venous access is associated with greater first-attempt success, fewer needle redirections, and a trend of fewer arterial punctures compared with the transverse orientation.

Randomized Controlled Trial
Evaluation of the Storz CMAC®, Glidescope® GVL, AirTraq®, King LTS-D™, and direct laryngoscopy in a simulated difficult airway.
The aim of this study was to compare first-attempt and overall success rates and success rates in relation to placement time among 5 different airway management devices: Storz CMAC, Glidescope GVL, AirTraq, King LTS-D, and direct laryngoscopy (DL). ⋯ Overall success rates for DL, King-LTS-D, and both video laryngoscope systems were not different. When time was factored into the model, the King LTS-D was more likely to be placed successfully.

Randomized Controlled Trial
Impact of stylet use in a simulated difficult airway model.
Stylet use during endotracheal intubation (ETI) is variable across medical specialty and geographic location; however, few objective data exist regarding the impact of stylet use on ETI performance. ⋯ Stylet use does not improve attempt time in a simulated difficult airway model for either inexperienced or experienced intubators.
