The Cryonics Institutes 217th Patient

by System Administrator / Monday, 25 October 2021 /


Cryonics Institute Case Report for Patient Number 217


CI patient #217 was an 88 year old male from Minnesota. The patient was a CI member at the time of his death. 


The patient died at a nursing home under hospice care at approximately 2 pm on October 17th, 2021.  The Cryonics support group from Minnesota was on standby and administered heparin and sodium citrate.  They packed the patient in ice and did chest compressions for a couple hours.  More details on the standby will be made available as we receive them.  The patient was taken to a funeral home and more ice was added.  The funeral home made arrangements to fly the patient to CI, while keeping him packed in ice.  The patient arrived at the CI facility on the 18th of October at 7pm. 


Upon the patient’s arrival at the CI facility, he was transferred to the operating table in the perfusion room. The nasal temperature upon his arrival was -.1c.


The head was perfused, but the body was not perfused. The perfusion was completed at 8:45pm.  During the perfusion there were 1 liter of 10% Eg solution and 2.5 liters of 30% Eg solution used, and 18 liters of 70% VM1 solution used.  The final refractive index of the effluents exiting the right jugular vein was 1.4162.  The final refractive index of the effluents exiting the left jugular vein was 1.4209. The average perfusion pressure was held at 115mm and metal cannulas were used.  Flow rate started at 0.4 liters per minute and was reduced to 0.34 liters per minute by the end of the perfusion. The nasal temperature was -1.4c at the end of the perfusion.


There were no blood clots noted during the perfusion.   There was good flow from the right jugular vein and very little flow from the left jugular vein. Significant dehydration of the head and face was noted along with a bronzing of the skin.  There was some edema in the neck at the end of the perfusion.


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.
