An Observational Study of Rocuronium 0.6 mg/kg Comparing Onset Time, Duration of Action and Effect on Intubation Conditions in Younger (18 - 40 Years) and Elderly Patients (> 80 Years)

Detailed Summary

The number of elderly patients (\>80 years) is increasing and a large proportion of these patients will require surgery and anaestheasia within the next decades. During anaesthesia NMBAs are used to facilitate tracheal intubation, from former studies it is reported that elderly patients are more sensitive towards muscle relaxants. It is unknown if there are differences in onset times of NMBAs between younger patients and elderly. The aim of this study is to determine the onset time, duration of action and effect on intubating conditions for rocuronium 0.6 mg/kg in patients aged 18-40 years and in patiens \>80 years. The hypothesis of this study is that rocuronium administered in elderly patients (\>80 years) has a longer onset time compared to younger patients.
