The aim of this study is to determine the onset time, duration of action and effect on intubation conditions of cisatracurium 0.15 mg/kg in elderly patients with age ≥ 80 years and in young patients aged 18 - 40 years.
The aim of this study is to determine the onset time, duration of action and effect on intubation conditions of cisatracurium 0.15 mg/kg in elderly patients with age ≥ 80 years and in young patients aged 18 - 40 years. The hypothesis of this study is that cisatracurium administered in elderly patients (>80 years) has a longer onset time and duration of action compared to younger patients.

intubation conditions are rated according to intubating difficulty score IDS when TOF-ratio is 0.
| within 10 minutes after administration of cistracurium |
| intubation conditions | intubation conditions are rated according to Fuchs-Buder score when TOF-ratio is 0. | within 10 minutes after administration of cisatracurium |
| Laryngeal morbidity | After 24 hours patients are asked about hoarseness and sore throat. Patients who experience either or both will be called 3 days postoperatively again. These two variables are assessed using a numeric ranking scale from 0 to 10. | 24 hours after surgery |
| Amount of ephedrine or metaoxedrine administered | If ephedrine or metaoxedrine is administered after induction of anaesthesia and until the patient is ready for properly positioning for surgery, it will be noted in the CRF, as well as the amount administered. Changes in blood pressure or heart rate are treated according to local guidelines. | within 10 minutes after administration of cisatracurium |
