To provide an evidence-based overview and update on the use of the Fastrach Intubating Laryngeal Mask Airway (FT-LMA) when used within operative and non-operative settings. ⋯ The FT-LMA has proven to be a useful difficult airway device both within and outside of the operating room. Effective ventilation is established in nearly all cases, and blind ETI is possible in the vast majority of cases if the optimal techniques described are used. Serious complications are uncommon.

Multicenter Study
The Canadian STOP-PAIN project - Part 1: Who are the patients on the waitlists of multidisciplinary pain treatment facilities?
The Canadian STOP-PAIN Project assessed the human and economic burden of chronic pain in individuals on waitlists of Multidisciplinary Pain Treatment Facilities (MPTF). This article presents the patients' bio-psycho-social profile. ⋯ This study highlights the severe impairment that patients experience waiting for treatment in MPTFs. Knowing that current facilities cannot meet the clinical demand, it is clear that effective prevention/treatment strategies are needed earlier in primary and secondary care settings to minimize suffering and chronicity.

Randomized Controlled Trial
Up-down determination of the ED(90) of oxytocin infusions for the prevention of postpartum uterine atony in parturients undergoing Cesarean delivery.
Use of the lowest effective dose of oxytocin may reduce side effects. This study was designed to determine the effective dose (ED)(90) of oxytocin infusion for an elective Cesarean delivery (CD) to prevent uterine atony. ⋯ In this study, we found the ED(90) of oxytocin required to prevent uterine atony and postpartum hemorrhage after an elective CD to be 0.29 IU.min(-1)-approximately 15 IU of oxytocin in 1 L of intravenous fluid administered over a one-hour period-(95% CI 0.15-0.43 IU.min(-1)). This oxytocin infusion dose is 30% less than the clinical infusions currently in use. It remains to be seen whether this dosing will be required for higher risk individuals or for labouring parturients undergoing non-elective CD. (Clinical Trial gov. NCT00785395).

Controlled Clinical Trial
No change in impedance upon intravascular injection of D5W.
Electrical impedance increases following test injections of non-conducting solutions around nerves; however, this increase should diminish rapidly with intravascular needle placement, wherein the systemic circulation will dissipate the solution. For this observational study, we hypothesized that the impedance increases significantly at the perineural space after an injection of 5% dextrose in water (D5W), but that it does not increase correspondingly at the intravascular location ⋯ The absence of a significant increase in impedance upon injection of D5W prior to injection of local anesthetic may provide useful information to warn of intravascular injection.

Various bibliometric citation indices have been used to evaluate research productivity and scientific impact, but recently, Hirsch's h-index has gained widespread recognition. Although described initially for physical sciences, h-indices are being used to assess research productivity and impact in other disciplines. ⋯ We describe the bibliographic characteristics of the research output of pediatric anesthesiologists in Canada. This study highlights the growing influence of scientometrics on the evaluation of scientific performance in medical specialties.
