ABSTRACT
We report two elderly cases in the extended care unit who were successfully treated for emitting a strange squealing sound with Sansonin-to. Case 1 was a 97-year-old female who was hospitalized with a strange squeal after repeated aspiration pneumonia. She made this strange sound especially during the night. This sound disappeared with the administration of Sansonin-to (TJ-103: 7.5g/day) except at the times of position change and diaper change, and she also became able to eat after practicing swallowing. Case 2 was an 80-year-old female who was hospitalized after a cerebral hemorrhage. She also made a strange squealing sound during the night. After administration of Sansonin-to, this sound was decreased, and she became able to sleep well at night and live actively with rehabilitation training in the daytime. With an aging society, troublesome behaviors due to dementia will be an increasing problem. These cases suggest that there may be certain conditions of elderly nighttime delirium that are treatable with Sansonin-to.
