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.
