Randomized Controlled Trial Comparative Study
Similar incidence of hypotension with combined spinal-epidural or epidural alone for knee arthroplasty.
We hypothesized that the incidence of hypotension during total knee replacement (TKR) surgery is lower in patients given combined spinal-epidural (CSE) anesthesia vs those receiving epidural anesthesia alone. ⋯ Combined spinal-epidural anesthesia and epidural anesthesia alone during TKR surgery are associated with the same incidence of hypotension with statistically and clinically similar hemodynamic responses.

The outbreak of severe acute respiratory syndrome (SARS) in 2003 presented major challenges to the safety of anesthesiologists and other healthcare workers (HCWs). This study determined the incidence of SARS transmission to HCWs who intubated patients and analyzed the concerns of HCWs regarding personal and patient safety. ⋯ Protection guidelines failed to completely prevent the transmission of SARS to HCWs. Nine percent of the interviewed HCWs who intubated patients contracted SARS. A Risk Analysis Framework is presented to facilitate the rapid integration of HCWs' experiences into practice guidelines.

Randomized Controlled Trial
Lack of a pre-emptive effect of low-dose ketamine on postoperative pain following oral surgery.
The aim of this study was to assess the effect of pre- vs postincisional low-dose iv ketamine on postoperative pain in outpatients scheduled for oral surgery under general anesthesia. ⋯ There was no benefit to pre-emptive administration of ketamine 300 microg x kg(-1) iv whether administered pre- or postoperatively.
