Impact of ambulatory surgery day of the week on postoperative outcomes: a population-based cohort study
Conclusion On a population level, there was a small effect of the day of the week of ambulatory surgery on outcomes; however, the clinical impact is likely not relevant. Certain surgical types may be more susceptible to a day of the week effect, but more research is needed to elucidate this notion. (Source: Canadian Journal of Anesthesia)

Undiagnosed vertebral hemangioma causing a lumbar compression fracture and epidural hematoma in a parturient undergoing vaginal delivery under epidural analgesia: a case report
Conclusion Vertebral fractures secondary to acute expansion of a vertebral hemangioma rarely occur during vaginal delivery. In such cases, the labour epidural technique and analgesia may challenge the physician in making the diagnosis. Postpartum severe back pain should be thoroughly investigated even in the absence of neurological deficits, and osseous spinal pathology should be considered in the differential diagnosis.

Efficacy of dexmedetomidine on postoperative shivering: a meta-analysis of clinical trials
Conclusions The present meta-analysis indicates that dexmedetomidine shows superiority over placebo, but not over other anti-shivering agents. Therefore, considering its high price and potential adverse events, dexmedetomidine may not be appropriate solely for the purpose of the prevention of postoperative shivering.

Estimated glomerular filtration rate better predicts 30-day mortality after non-cardiac surgery than serum creatinine: a retrospective analysis of 92,888 patients
Abstract Background Serum creatinine is the most commonly used indicator of renal function, but its derivative, estimated glomerular filtration rate (eGFR), has been shown to be superior in non-surgical settings. It remains unknown if eGFR better predicts postoperative mortality in non-cardiac surgical patients. We thus tested the hypothesis that eGFR predicts 30-day mortality after non-cardiac surgery better than serum creatinine. Methods We evaluated patients who had inpatient non-cardiac surgery of at least one hour duration during January 2006...

The incidence, success rate, and complications of awake tracheal intubation in 1,554 patients over 12 years: an historical cohort study
Abstract Purpose Awake tracheal intubation is one recommended option to address select situations in the management of a patient with an anticipated difficult airway. A scarcity of data exists on how often awake intubation is performed or whether its use is changing over time, particularly with the increasingly widespread availability of video laryngoscopy. This retrospective database review was undertaken to determine the incidence, success, and complications of awake intubation and the incidence of other tracheal intubation techniques in the operating room over a 12-yr period (2002-2013) ...

Apolipoprotein epsilon 4 genotype is associated with less improvement in cognitive function five years after cardiac surgery: a retrospective cohort study
Abstract Purpose Cognitive performance after cardiac surgery can be impaired, and genetic risk factors have previously been suggested. When compared with other isoforms of the gene, the apolipoprotein epsilon 4 (APOE4) allele is associated with worse outcomes in many neurologic disorders. We hypothesized that the APOE4 allele is associated with less favourable cognitive function five years after surgery. Methods Caucasian patients enrolled in previously reported prospective cognitive trials in both cardiac and non-cardiac surgery participated in t...
