Randomized Controlled Trial Comparative Study
Intermittent reinflation is safe to maintain oxygenation without alteration of extravascular lung water during one-lung ventilation.
To investigate whether a maneuver for repeated cycles of collapse and reexpansion of the operative lung, termed "intermittent reinflation" (IR), to counter hypoxemia during one-lung ventilation (OLV), results in a time-dependent alteration of extravascular lung water. ⋯ Intermittent reinflation had a beneficial effect on oxygenation during OLV, without any significant effects on EVLW or postoperative outcomes.

Randomized Controlled Trial Comparative Study
Comparison of the Airtraq and McCoy laryngoscopes using a rigid neck collar in patients with simulated difficult laryngoscopy.
To determine the efficacy of the Airtraq versus the McCoy laryngoscope as intubation devices with the neck stabilized by a rigid cervical collar. ⋯ Intubation time was shorter with the Airtraq than the McCoy laryngoscope, even though the overall success rates between the two devices were similar.

Randomized Controlled Trial Comparative Study
Effective low dosage of mepivacaine in ultrasound-guided axillary nerve block: a double-blinded, randomized clinical trial of efficacy in patients undergoing distal upper extremity surgery.
To evaluate two low-dose volumes (20 mL or 30 mL) of 1.5% mepivacaine solution used for ultrasound-guided axillary blockade for outpatients undergoing distal upper limb surgery. ⋯ Low volumes (30 mL or 20 mL) of 1.5% mepivacaine provides satisfactory anesthesia for ambulatory distal upper limb surgery with no significant difference in clinical outcomes.

Randomized Controlled Trial
Efficacy of computer-based video and simulation in ultrasound-guided regional anesthesia training.
To determine the effectiveness of a short educational video and simulation on improvement of ultrasound (US) image acquisition and interpretation skills. ⋯ A short educational video with interactive simulation significantly improved knowledge of US anatomy, but failed to improve hands-on performance of US scanning to localize the nerve.
