[Muscle relaxation with atracurium in myasthenia gravis].
This report concerns a narcosis in a 42-year-old female patient suffering from myasthenia gravis in a state of clinical remission after thymectomia. Six months after thymectomia relaxometric control (Datex AMG) was performed while the patient underwent major colorectal surgery. We found a persisting sensitivity to relaxants during isoflurane anaesthesia supplemented with fentanyl. During 270 minutes of anaesthesia we needed only 25 mg atracurium (0.4 mg/kg bodyweight) only 57% of a theoretical normal dose. This is the result of a continuing muscular weakness in asymptomatic patients suffering from clinically reliable myasthenia gravis. Therefore, a reduced demand for muscle relaxants can be expected in these patients.
