CI Case 269
Cryonics Institute Case Report for Patient Number 269
CI patient #269 was a 76 year old female from Rhode Island. The patient was a CI member at the time of her death.
The patient died at home under hospice care at approximately 2am on April 3, 2025. When the next of kin observed the patient had stopped breathing, the next of kin called the hospice nurse to pronounce legal death. The next of kin then called the local funeral home to pick up the patient and cool her in ice. The patient was not injected with heparin by the funeral director, but the patient was receiving low doses of heparin due to being immobile for an extended period of time. The patient was driven to CI and arrived at 11:34pm on April 3, 2025.
Upon the patient’s arrival at the CI facility, she was transferred to the operating table in the perfusion room. The nasal temperature upon her arrival was 1.5c.
Hillary McCauley performed the perfusion. The perfusion started at 12:19 am and was completed at 2:20 am. During the perfusion there were 3 liters of 5% EG solution, 3 liters of 10% EG solution, 3 liters of 30% EG solution used, and 27 liters of 70% VM1 solution used. Only the patient’s head was perfused. The final refractive index of the effluents exiting the right jugular vein was 1.4228. The final refractive index of the effluents exiting the left jugular vein was 1.4234. The average perfusion pressure was held at 101mm and metal cannulas were used. Flow rate started at 0.33 liters per minute and was reduced to 0.31 liters per minute by the end of the perfusion. The nasal temperature was -4.9c at the end of the perfusion.
There were no blood clots noted during the perfusion and there was good flow from both of the jugular veins. Significant dehydration of the head and face was noted along with a bronzing of the skin and no edema.
The patient was then transferred to the computer controlled cooling chamber to cool to liquid nitrogen temperature. The human vitrification program was selected and the time needed to cool the patient to liquid nitrogen temperature was five days and 11 hours. The patient was then placed in a cryostat for long-term cryonic storage.
