CI Case 273

Cryonics Institute Case Report for Patient Number 273

CI patient #273 was a 72 year old male from New Hampshire. The patient was a CI member at the time of his death.

The patient died on July 6, 2025 while vacationing in Connecticut. The patient was cooled with ice by hospital staff and placed in refrigeration. The Medical Examiner did take custody of the patient, but after the family and CI staff expressed the patient’s cryopreservation wishes and objection against autopsy, they agreed not to autopsy and release the patient to the local funeral home. The funeral home added additional ice to the patient and began making transportation arrangements. The patient was driven to the CI facility and arrived on July 8, 2025 at 6:00 am.

Upon the patient’s arrival at the CI facility, he was transferred to the operating table in the perfusion room. The patient’s temperature was 7.1c.

Hillary McCauley performed the perfusion. The perfusion started at 6:51 am and was completed at 8:27 am. During the perfusion there were 1.5 liters of 5% EG solution, 2 liters of 10% EG solution, 2.5 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 1.4215. The final refractive index of the effluents exiting the left jugular vein was 1.4220. The average perfusion pressure was held at 115mmHg and metal cannulas were used. Flow rate was held at 0.35 L/min for the perfusion. The nasal temperature was -3.9c at the end of the perfusion.

There were no blood clots noted during the perfusion and the flow from both of the jugular veins was consistent. Bronzing of the skin was noted throughout the patient’s head.

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.
