Vor der Operation müssen Sie acht Stunden nüchtern bleiben.
Before the operation, you must remain fasting for eight hours.
Medical context
In a medical context, 'nüchtern' (fasting) is almost always used with the verbs 'sein' (to be) or 'bleiben' (to remain). You are fasting for an examination or must remain fasting for an operation.
