If they sent her home they obviously think the likelihood of a subarachnoid hemorrhage (from a burst vessel or aneurism in the brain) is not very high. Such a thing is true medical emergency, since the consequences can be so devastating. From: sbharris@ix.netcom.com(Steven B.

Fox, M.D. I'd like to know, also. It's not as though iatrogenicus laboratorius fulminans doesn't go on. A family member of mine recently sustained a severe facial fracture in an athletic accident, and besides multiple other facial fractures, also had cribiform plate fracture on MRI. She was leaking clear fluid from the nose. I've seen this kind of thing before. I asked the nurses to test the fluid for glucose with a glucometer (cost--$2, maybe). CSF would have lots of glucose, mucus almost none. I asked the surgeon to do it. I asked the neurologist to do it. Nobody did it. The next day someone had the bright idea that to make sure it wasn't CSF by doing a radiotracer scan in which Tc-99m is injected into the lumbar subdural space and tracked to see if it shows up in the sinuses. Not surprisingly, it did. Yes, it was CSF. Cost: around $800 and some pain. Plus, the admission that with that much fluid they'd probably have put in a lumbar decompression catheter, even if it had come out negative, just to be sure. Which they did. What a tremendous frigging waste of money. Technology substuted for thinking, just because it's harder to document thinking and we don't value it anyway. Due to the fact that most people are convinced they do it as well as anybody else. From: sbharris@ix.netcom.com(Steven B.

This then led to what appears to be a poorly done >spinal tap which led to all the tests. The story of modern medicine, right. Is the system set up so that someone especially skillful at doing LPs, so as to save $3,000 worth of fancy scans, is paid even a fraction of that, in acknowledgement of his or her skill and ability to save money? Nope. So such people never appear. If there was a bounty of $1000 a pop on getting a crystal clear tap on a person suspected of subarachnoid bleed, you can bet that such people would appear. A whole subspeciality would be created, in fact. But the market does not opperate, and so we pay. And pay. And pay. Other countries aren't any smarter about this. They just limit the number of scanners. So some of their people who have small subarrachnoid bleeds just don't get scanned-- it being assumed they have a slightly bloody tap, when they do, due to poor technique or bad luck. Come back tomorrow of the next day if you're not better. And those people suffer the cerebral consequences. But they're rare, so tough bananas. The system does anything, and will kill nearly anybody, rather than pay people what a machine gets, if it's a lot of money. Nobody's jealous of an MRI machine, you see. Except possibly me. (I think the MRI scanner lifestyle is way overboard, and I've seen one too many of the blasted things on Caribbean cruises with a girl on each keyboard. They seem to attract chicks like a magnet.) >Now diagnosed with "cluster migraines". > >Brian |
