All tests so far do not indicate a stroke. He had an echo, EKG, blood work, head CT scan, and we are waiting on doppler carotid test. The floor doc and surgeon do not believe it was a stroke and think it falls back on th meds, anesthesia, and possibly effects of heart lung bypass machine. He has been his old self, and very anxious to get home. Now I have to ask, why do they keep these rooms so damn cold? If they get this test done, (almost 3pm) and get results we can go home. But they have to do that test and read it, so crossing our fingers.
