Cryonics Institute Case Report for Patient Number 172


CI patient #172 was an 86 year old female from Illinois.  The patient was a CI member at the time of her death.


The patient died in the hospital and was pronounced at 4:05 pm on August 17, 2018. After pronouncement took place, the funeral director that the family had contracted with cooled her down with water ice, injected Heparin, and performed chest compressions. They then transferred her to the funeral home and worked quickly to obtain the paperwork needed for her transportation. 


The patient arrived at the CI facility at 2:00 am on the 18th, approximately 10 hours after death.  The patient was in a body bag with a generous amount of ice. The nasal temperature upon her arrival was 22c. 


Hillary Martenson performed the perfusion.  The perfusion was completed at 4:40 am.  During the perfusion there were 5 liters of 10% Eg solution and 10 liters of 30% Eg solution used, and 40 liters of 70% VM1 solutions used.  The final refractive index of the effluents exiting the right jugular vein was 1.4209.  The final refractive index of the effluents exiting the left jugular vein was 1.4208. The average perfusion pressure was held at 130mm and metal cannulas were used. Flow rate started at 1.32 liters per minute and was reduced to 0.55 liters per minute by the end of the perfusion. The nasal temperature was -6.4c at the end of the perfusion. 


There were no blood clots noted during the perfusion and there was good flow from both jugular veins. There was an attempt to perfuse the body, but there was a lot of edema throughout the patient’s body upon arrival. There was very minimal dehydration and bronzing of the body. The perfusion of the body was stopped at 3:47 am, as there was no evidence of any further progression. Significant dehydration of the head and face was noted along with a bronzing of the skin. No edema was noted in the patient’s head or face. 


The patient was then transferred to the computer controlled cooling chamber to cool to liquid nitrogen temperature.  The human vitrification program was selected and when the patient reached liquid nitrogen temperature, she was then placed in a cryostat for longterm cryonic storage.
