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.

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.

Randomized Controlled Trial
Use of a chlorhexidine-impregnated patch does not decrease the incidence of bacterial colonization of femoral nerve catheters: a randomized trial.
Femoral nerve catheter (FNC) insertion is commonly performed for postoperative analgesia following total knee arthroplasty (TKA). A wide range of rates has been reported relating to the bacterial colonization of catheters complicating FNC insertion. The BIOPATCH® is a chlorhexidine (CHG) impregnated patch designed to inhibit bacterial growth for days. The BIOPATCH has proven to be effective at decreasing bacterial colonization in epidural and vascular catheters. We hypothesized that the BIOPATCH would be effective at decreasing the rates of FNC bacterial colonization. ⋯ The baseline rate of bacterial colonization of FNCs is quite low in the setting of short-term use, CHG skin decontamination, ultrasound guidance, subcutaneous tunneling, and perioperative antibiotic therapy. No benefit was shown by using the BIOPATCH in this patient population. (ClinicalTrials.gov number: NCT01411891).
