Canadian physicians are faced with an increasing frequency of drug shortages. We hypothesized that drug shortages have a clinical impact on anesthesia care in Canada. ⋯ Drug shortages are common in anesthetic practice in Canada. This state of affairs may have a negative effect on how anesthesiologists practice anesthesia and may be associated with adverse patient outcomes.

In 2007, the World Health Organization created a Surgical Safety Checklist (SSC) that encompassed a simple set of surgical safety standards. The threefold purpose of this study was to add ambulatory-specific items to the SSC, to introduce the items into an ambulatory surgical facility, and to determine if patient outcomes regarding postoperative pain and nausea/vomiting improved following implementation. In addition, safety attitudes, antibiotic timing, regional anesthesia/nerve blocks, preemptive pain medications, prophylactic antiemetics, length of stay, and hospital admission were also assessed. ⋯ Potential reasons for lack of uptake and integration include poor "user" buy-in, an overly lengthy checklist, and lack of prioritization of ambulatory-specific items. A shortened SSC was developed based on the results of this study. This trial was registered at ClinicalTrials.gov ID: NCT00934310.

Clinical Trial
Cerebrovascular autoregulation in critically ill patients during continuous hemodialysis.
In chronic renal failure, intermittent hemodialysis decreases cerebral blood flow velocity (CBFV); however, in critically ill patients with acute renal failure, the effect of continuous venovenous hemodialysis (CVVHD) on CBFV and cerebrovascular autoregulation (AR) is unknown. Therefore, a study was undertaken to investigate the potential effect of CVVHD on CBFV and AR in patients with acute renal failure. ⋯ Compared with patients with intermittent hemodialysis, CVVHD did not influence CBFV and AR in critically ill patients with acute renal failure, possibly due to lower extracorporeal blood flow, slower change of plasma osmolarity, and a lower fluid extraction rate. In a subgroup of patients with sepsis, the AR was impaired at baseline in more than half of the patients, and this was reversed during CVVHD. The trial was registered at ClinicalTrials.gov ID: NCT01376531.

Controlled Clinical Trial
In non-obese patients, duration of action of rocuronium is directly correlated with body mass index.
Administration of neuromuscular blocking agents using a dose calculated on actual body weight carries a risk of prolonged duration of action in obese patients whose body mass index (BMI) is > 30 kg · m(-2). In the present study, we hypothesized that there could be a correlation between BMI and the duration of action of rocuronium administered according to actual body weight in non-obese patients, in particular, overweight (BMI 25-30 kg · m(-2)) and underweight patients (BMI < 18.5 kg · m(-2)). ⋯ In adult female patients with a BMI in the range of 15-30 kg · m(-2), the duration of action of rocuronium increases with BMI when the drug is administered on the basis of mg per actual kg body weight.
