It pays to procrastinate

Last night two young oncologists (Dr. Tao and a man whose name is as long as any name I have ever seen and irreproducible) told me that B was still having seizures as detected by the EEG monitoring device that is attached to her all the time as part of the neurosurvaillance procedure. In the seizure mode, several neurons near the the tumor are firing in synchrony. The fear is that they could entrain the whole brain in what is (or used to be) known as a grand mal seizure. This is serious stuff and they are trying to halt the seizure before that happens. Since the keppra and ativan are not completely successful, the seizure team wishes to use phenobarbital in an attempt to quiet the remaining coherent oscillations. This has the risk of stopping B's breathing. If that happens, they'll need to intubate to force her to breathe. I was asked to approve the procedure both as to the use of pheno and intubation, if necessary. At my request, they greed to stay with the ativan until Thursday morning.

I had sent off few notes during the hectic Wednesday in S-K and went home having eaten in their cafeteria. I answered some emails and went to bed. Early next morning, I checked the email and found a letter from Sara at NWU Med School. She reported this: We have talked with a Chicago friend who is a neurologist. His specialty is not oncology, but in his own experience, patients on ORAL phenorbital show improvement within 48 hours, and do not need intubation. It is the IV treatment with much higher doses that carries the risk that breathing might stop. Is there a chance to use oral phenorbital? Or do the doctors at Sloan-Kettering think that it is really urgent to get her out of this subthreshold oscillatory state, and that the IV delivery of a high dose is the only effective way to do so? It seems that the oral treatment, if feasible, would be less of a trauma. But only the local doctors can evaluate the urgency factor."

On reading this, I immediately tried to phone Dr. Tao, who was on night duty, to discuss this with her and reached her at the nurses' station at 6:00. I have trouble hearing what Dr. T. says even when she is in front of me. On the phone, I heard her less well so I won't try to repeat what I thought she said for fear of misrepresenting her statements. But the upshot was that the plan was still in place. I went to the Beth Israel clinic for its eight o'clock opening to have my wrist re-bandaged and got to S-K by nine. (It seems weird to go to a clinic for minor attention and then to a hospital for a visit when the hospital could easily do it all.) B's speech was somewhat improved, though it was not clear what she was trying to say much of the time. The surprise to me was that they had not yet administered the phenobarbital. The nurse on duty had no instructions about this. Just before lunch time, Dr. Omuro appeared on rounds with a very few senior looking associates. He said that the family had refused phenobarbital so they had not administered it. I told him that I had accepted its use but had merely asked for a delay till morning. He said that in that case they would proceed. I told him of the news from Northwestern and he said of course they were going to do oral pheno. It was a flying visit but I suppose that we had covered the essentials. Soon after the departure of the oncology team, a doctor whom we had seen once before appeared and tried to get Barbara to sing Happy Birthday. She said she had missed the group on rounds and would try to catch them up. I asked whether I could first ask an indelicate question. She agreed and I asked how the confusion about what I had decided about pheno could have arisen and was it not a serious problem. She said it was a simple miscommunication and nothing serious. She departed saying that she would return soon and seven hours later has still not been seen. I begin to realize that various unanticipated things must arise in such places and many of them involve very serious issues.

It is very difficult for a layman to judge the importance of various issues, especially one who works on chaos or turbulence where small causes have big effects. The doctor with the long name came and said that since B did not have seizures during the night it was not clear that they would need to administer the pheno. He said he would check with the two senior people in charge. He returned and said that it seemed that if they did use pheno, it might well be oral. They said they would authorize a puree meal and, if she ate it, she would be cleared for oral pheno. So I ordered potato leek soup, apple sauce, chocolate ice cream and apple juice and she ate it all for lunch. She even asked for more apple sauce. A nurse fed her but she took over in the middle of the ice cream. At dinner time another nurse ordered a pureed meal and I fed her some of it and the rest she ate (with gusto) herself. So swallowing is no problem and oral phenobarbital is on schedule for 10:00 when it will also help her sleep.
