Review Meta Analysis Comparative Study
Perineural steroids for trauma and compression-related peripheral neuropathic pain: a systematic review and meta-analysis.
Perineural steroids are often used to treat chronic peripheral neuropathic pain (NP) secondary to trauma or compression. Nevertheless, when compared with local anesthetics (LA) or conventional medical management (CMM), their efficacy and safety in patients with trauma or compression-related neuropathic pain syndromes is unclear. The purpose of this systematic review and meta-analysis was to determine the efficacy and safety of perineural steroids in compression or trauma-related NP after one to three months of injection. ⋯ Perineural steroids may provide analgesic efficacy for one to three months in patients with chronic peripheral NP of traumatic or compressive origin; however, the strength of this recommendation is weak. Well-designed large randomized studies are required.

Multicenter Study
Residents' reluctance to challenge negative hierarchy in the operating room: a qualitative study.
Our aim was to clarify how hierarchy influences residents' reluctance to challenge authority with respect to clearly erroneous medical decision-making. ⋯ Study results showed that hierarchy played a dominant role in the functioning of the operating room. Participants spoke of both the positive and negative effects of such a hierarchical learning environment. The majority of participants described a negative perception of hierarchy as the norm, and they employed many coping strategies. This study provides insight into how a negative hierarchical culture can adversely impact patient safety, resident learning, and team functioning. We propose a theoretical model to describe challenging authority in this context.

Randomized Controlled Trial Comparative Study
A randomized comparison between the i-gel™ and the air-Q™ supraglottic airways when used by anesthesiology trainees as conduits for tracheal intubation in children.
Supraglottic airways are commonly used as conduits for fibreoptic bronchoscopy (FOB)-guided intubation in pediatric patients. We hypothesized that anesthesiology trainees with limited prior experience with FOB-guided intubation through a supraglottic airway in children would intubate the trachea faster through the air-Q™ supraglottic airway than through the i-gel™. ⋯ Contrary to our hypothesis, both the air-Q and i-gel supraglottic airways served as effective conduits for FOB-guided tracheal intubation in children when performed by trainees with limited prior experience. The i-gel, however, was associated with more problems during device removal following tracheal intubation. This study was registered at http://clinicaltrials.gov/show/NCT02189590 .

Delirium after cardiac surgery is a serious complication, increasing morbidity and mortality. Despite its high expectations, off-pump coronary artery bypass grafting (OPCAB) has largely failed to reduce the incidence of postoperative neurological complications. To further investigate the reasons for this failure, we used perioperative brain magnetic resonance imaging (MRI) to determine the relation between MRI findings and postoperative delirium. ⋯ Magnetic resonance imaging findings of new cerebral ischemic lesions, carotid stenosis, and deep subcortical white matter hyperintensity correlated significantly with postoperative delirium in patients who had undergone OPCAB surgery.
