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.

Clinical Trial Observational Study
Usability and performance characteristics of the pediatric air-Q® intubating laryngeal airway.
The air-Q® intubating laryngeal airway (ILA) is a supraglottic device (SGD) designed specifically to function as both a primary airway and a bridging device and conduit for fibreoptic intubation in difficult airway scenarios. This observational study evaluated the usability and performance characteristics of pediatric air-Q ILA sizes 1.0, 1.5, 2.0, and 2.5 when used as a primary airway. ⋯ The air-Q ILA functions acceptably as a primary SGD in infants and children. The OLPs are lower than published values for the ProSeal laryngeal mask airway (LMA ProSeal™), the current pediatric SGD of choice, but adequate tidal volumes are readily achievable. The fibreoptic views of the glottis portend well for fibreoptic intubation through the device. (This trial was registered at clinicaltrials.gov number, NCT00885911).
