Cervical dilation was carried out with ease and minimal trauma. Cervical dilators #1 through #4 were passed with ease. A #3 Sime curette was passed and the endometrium was curetted. A specimen was sent to the laboratory. Bleeding was minimal at the termination of the procedure.

The speculum was removed. At that point it became apparent that the patient was making a slow recovery from anesthesia.

Susan rested her weary right hand by letting it dangle by her side. She had a habit of writing by holding a pencil or pen so tightly that blood flow was restricted. The blood tingled as it returned to her fingertips. Before going back to work, she took several sips of her coffee.

The pathology report described the endometrial scrapings as proliferative in character. The diagnosis was then listed as an ovulatory uterine bleeding with a proliferative endometrium. No clue there.

Next Susan turned to the most interesting page: the initial neurology consult, signed by a Dr. Carol Harvey. Without knowing the meaning of most of what she wrote, Susan copied the consult note as well as she could. The handwriting was atrocious.

HISTORY: The patient is a twenty-three-year-old, white female admitted to the hospital with a problem of (illegible phrase). Past medical history of self and family negative for significant neurological disorders.

Patient’s pre-op workup (illegible phrase). Surgery itself uneventful and immediate result diagnostic and most likely curative of the presenting complaint. However, during surgery some minor problems with the blood pressure were noted, and after surgery there was noted a prolonged unconsciousness and apparent paralysis. Overdose of succinylcholine and/or halothane ruled out. (Entire sentence totally illegible.) EXAMINATION: Patient in deep coma unresponsive to spoken word, light touch or deep pain. Patient appears to be paralyzed although trace deep tendon reflexes elicited from both biceps and quadriceps symmetrically. Muscle tone decreased but not totally flaccid.

Pendulousness increased. No tremor.

Cranial nerves: (illegible phrase) ... pupils dilated and unresponsive.

Absent corneal reflex.

Square-Wave Nerve Stimulator: Persistent although decreased function of the peripheral nerves.

Cerebral Spinal Fluid (CSF): Atraumatic puncture, clear fluid, opening pressure 125 mm of water.

EEG: Flat wave in all leads.

IMPRESSION: (illegible sentence), (illegible phrase) ... with no localizing signs ... (illegible phrase) ... coma due to diffuse cerebral edema is the primary diagnosis. The possibility of a cerebral vascular accident or stroke cannot be ruled out without cerebral angiography. An idiosyncratic response to any of the agents used for anesthesia remains a possibility although I believe ... (illegible phrase).

Pneumoencephatography and/or a CAT scan may be of help but I believe it would be of academic interest only and would not provide any additional information for diagnosis in this difficult case. The EEG with its suppression of all organized and otherwise activity certainly suggests extensive brain death or damage. This same picture has been seen with tranquilizer/ alcohol combinations but it is extremely rare. There are only three cases in the literature. Whatever the cause, this patient has suffered an acute insult to the brain. There is no chance that this patient represents any degenerative neurological syndrome.

Thank you very much for letting me see this very interesting patient.

DR. CAROL HARVEY, resident, neurology

Susan cursed the handwriting as she surveyed the many blanks on her own notebook sheet. She took another sip of coffee and turned the page in the chart. On the next pa® was another note from Dr. Harvey.

February 15, 1975. Follow up by Neurology

Patient status = unchanged. Repeat EEG = no electrical activity. CSF

laboratory values were all within normal limits.

IMPRESSION: I have discussed this case with my attending and with other neurology residents who agree on the diagnosis of acute brain insult leading to brain death. It is also the general consensus that cerebral edema from acute hypoxia was the immediate cause of the problem. The cause of the hypoxia was probably some sort of cerebral vascular accident perhaps due to a transient blood clot, platelet clot, fibrin clot, or other embolus related to the endometrial scraping. Some sort of acute idiopathic polyneuritis or vasculitis may have played a part.

Two papers of interest are: “Acute Idiopathic Polyneuritis; a Report of Three Cases,” Australian Journal of Neurology, volume 13, Sept. 1973, pp 98-101.

“Prolonged Coma and Brain Death Following Ingestion of Sleeping Pills by Eighteen Year Old Female,” New England Journal of Neurology, volume 73, July 1974, pp 301-302.

Cerebral angiography, pneumoencephalography, and a CAT scan can be done, but it is the combined opinion that the results would be normal.

Thank you very much

DR. CAROL HARVEY

Susan let her aching hand rest for a few moments after copying the lengthy neurology notes. She moved on in the chart, passing the nurses’

notes until she reached the laboratory results. There were numerous X-ray reports, including a normal series of skull X-rays. Next came the extensive chemistry and hematology reports, which Susan laboriously copied into her notebook pages. Since all the results were essentially normal, Susan concentrated on finding out if there were any changes between the pre-op values and the post-op values. There was only one value that fell into this category; after the operation Nancy Greenly had exhibited a higher serum sugar as if she had developed a diabetic tendency. The serial EKGs were not very revealing, although they did show some nonspecific S and ST wave changes following the D&C.

However, there was no pre-op EKG to compare.

Finishing, Susan closed the cover of the chart and leaned back, stretching her hands up toward the ceiling. At the very limit of her stretch, she grunted and exhaled. She leaned forward and glanced over the eight pages of minute handwriting which she had just completed. She felt no further in her investigation but she did not expect to. Much of what she had copied she really did not understand.

Susan believed in the scientific method and she believed in the power of books and knowledge. For her there was no substitute for information.

Although she did not know very much about clinical medicine, she had the positive feeling that by combining method with information she could solve the problem at hand—why had Nancy Greenly lapsed into coma.

First she had to gather as much observational data as possible; that was the purpose of the charts. Next she had to understand the data; for that she must turn to the literature. Analysis leading to synthesis: pure Cartesian magic. Susan was optimistic at this stage. And it did not faze her that she did not understand much of the material she had taken from Nancy Greenly’s chart. She felt confident that within the maze of information were critical points which could lead to the solution. But to see it Susan needed more information, a lot more.

The hospital medical library was on the second floor of the Harding building. After multiple false starts Susan was directed to a flight of stairs which led up to the personnel office, and past it, to the library itself.

It was called the Nancy Darling Memorial Library, and as Susan entered she passed a small daguerreotype of a matronly woman dressed in black.

A copper plaque on the frame was engraved: In fond memory of Nancy Darling. Susan thought the name Nancy Darling, with its amorous connotations, hardly fitted the prim scowling figure. But it was New England one hundred percent.

With the reassuring warmth of the books about her, Susan felt instantly at home in the library, in sharp contrast to her feelings in the ICU and the hospital in general. She put down her notebook and got her bearings. The center of the room, with its two-storied ceiling, had large oak tables with black academic colonial-style chairs. The
