Treatment has finally started. They connected Isita to a complicated array of computerised syringe drives at about 6pm this evening. She is now sleeping very calmly. 

It is a relief to have got to this point, even though it is the start of a hard road. Our immediate concerns are, of course, how to deal with any side-effects. We also hope that the treatment, as well as being effective, will quickly remove the pain that she had endured the past couple of weeks.
