In Summary

A-14-year old girl from London was suffering & dying from cancer, it is when she decided to get her body preserved cryogenically by freezing. It is hoped to retrieve her body one day when science can bring her back to life.

Never die!

Cryogenic preservation is amethod of protecting the living tissue from natural decaying process by freezing at -196OC. At this temperature, none of the microbes can sustain on the tissue to initiate putrefaction.  This 14-year-old girl was suffering a from stage 3 cancer, which is when she decided to get her body preserved after death.

 “I don’t want my body to be buried and eaten by little creatures. I hope I can come back to life one day when science is far more advanced than today” – she said. The London high court had granted her permission to proceed with preservation process. There are many regulations and rules that need to be followed for the procedure depending on the country one is living.  

How is the human bodycryogenically preserved?

There are basically four stages involved in the cryopreservation of thehuman body. These four protocols need to be flawlessly established in order to successfully preserve thebody.

  1. Deployment and Standby: Before you die, you need to sign in the consent to acquire your body after death. All legal formalities need to be taken care before death itself. All necessary arrangements should be made to get the company informed by the time of death. There are a couple of companies around the world who provide these kinds of service. The most famous one is Alcor Life extension foundation from Arizona.
  2. Stabilization: The legal death is pronounced soon after the heart functioning stops. But biologically the brain still retains some of its functions and it is these remaining life that needs to be preserved. Soon after your legal death, the medical team injects you with heparin- a chemical agent that prevent coagulation of blood. Ventilation is still kept until the body is preserved and the body is moved toan ice pack.
  3. Cryoprotectant perfusion: The body is not directly frozen in liquid nitrogen since 75% of thebody is water and sudden freezing might shatter the cells. Instead, the medical team initiates the vitrification process- the water content in cells are replaced by a stable chemical mixture that can withstand low temperatures.
  4. Cryogenic cooling: Before putting thebody into liquid nitrogen it is cooled down to -130OC in a dry ice bed. Finally, thebodyis stored in a liquid nitrogen filled chamber at -196 OC.

But..?

There are many ethical issues persisting with preservation of thebody. But mummification and other preservation process are followed since ancient times, which stands in favor of cryogenic preservation. It almost costs $0.125 million for the whole process, whereas smaller body parts like thebrain can be stored for much lesser costs. However, some drawbacks exist even with today’s technology which prevents complete preservation of organs like kidney, liver etc. And moreover, any fault in the thawing process might completely damage the body in future.
