Multicenter Study
Epidemiology of acute kidney injury in Canadian critical care units: a prospective cohort study.
We undertook this study to characterize the epidemiology of acute kidney injury (AKI) in Canadian critical care units. We aimed to identify predictors of mortality for patients diagnosed with AKI. ⋯ Acute kidney injury is a common complication of critical illness in Canada. The development of even the mildest stage of AKI is associated with a substantially higher risk of death. At AKI diagnosis, routine clinical data may be helpful for predicting adverse outcomes.

Review
Perioperative management of the severely obese patient: a selective pathophysiological review.
Obesity is widespread, yet it is often understood primarily as a disorder of body structure. This article provides anesthesiologists with a synopsis of recent research into the complex pathophysiology of obesity. It emphasizes the importance of this information for the perioperative planning and management of this patient group and for reviewing some of the major perioperative challenges. ⋯ The literature clearly highlights the complexity of severe obesity as a multisystem disease, and anesthesiologists caring for these patients perioperatively must have a sound understanding of the changes in order to offer the highest quality care to these patients.

Case Reports
Case report: unusual complication during outpatient continuous regional popliteal analgesia.
Continuous regional anesthesia applied as pain therapy at home is clinically established standard practice after upper and lower limb surgery. Persistent motor block at discharge or after continuous infusion of local anesthetics, however, might lead to complications related to the insensate extremity. We report a rare case of a foot fracture due to stumbling after continuous sciatic nerve block at home and discuss the related clinical implications. ⋯ The true incidence of complications related to falls at home associated with lower extremity blockade remains unknown, as symptoms of possible complications may be masked by the effects of the local anesthetic. However, with increasing use of postoperative regional anesthesia, it is mandatory to develop and adhere to clinical care maps, and to elaborate and teach strategies to further enhance patient safety.

Comparative Study
A regional anesthesia-based "swing" operating room model reduces non-operative time in a mixed orthopedic inpatient/outpatient population.
We recently reported on the efficacy of a new "swing" room model involving two alternating ORs and regional anesthesia in increasing operating room (OR) throughput in a dedicated ambulatory orthopedic surgery facility. The purpose of this study was to evaluate this model in a main OR suite setting with typical mixed inpatient/outpatient cases. ⋯ The implementation of a "swing" room care model based on ultrasound-guided regional anesthesia in a typical mixed inpatient/outpatient population decreased non-operative times, increased throughput, and improved recovery profiles compared with case-matched historical controls in the traditional model under general anesthesia.

Case Reports
Case reports: iatrogenic bronchial rupture following the use of endotracheal tube introducers.
Endotracheal tube introducers are often used in difficult tracheal intubations, but they are rarely deemed responsible for airway injuries. There have been only a few reports of severe complications, such as pharyngeal perforation, mainstem bronchus bleeding, perforation of the tracheal mucosa, and tracheal abrasion associated with hemopneumothorax. Using a computed tomography (CT) scan, we illustrate two cases of non-severe airway injuries related to endotracheal tube introducers. ⋯ These two cases show that airway damage related to endotracheal tube introducers may not be exceptional. It is not unusual to have some blood on an airway management device, and the rate and severity of these lesions are unknown. However, damage to the airway can be avoided by adapting preventive techniques during tracheal intubation.
