According to Dr. Sergio Canavero the extensive surgery will cost £7.5million and take roughly 36 hours to complete. The surgery will also require 150 doctors and other medical staff. In order for Spiridonov to have a hopeful successful procedure, the new body would need to come from a donor who is brain dead but healthy in all other aspects.
The procedure is very tedious, involving both the donor and patient having their heads decapitated at the spinal cord simultaneously, using a very sharp blade for a clean, perfected cut. The patient’s head would then be connected to the new body using a glue-like adhesive called polyethylene glycol to fuse the patient’s spinal cord to the donor’s spinal cord. Basic body functions such as blood flow and muscle movement would work after Dr. Canavero stitches blood vessels and muscles together. The patient would then be put into four week coma to prevent movement until the head and body heal properly.
After the four week coma, the patient would wake up and would be able to move their body and speak. The patient would be given a power immunosuppressant would help the new body from being rejected.
This surgery would be the first of its kind. The medical world doesn’t agree with the surgery however, Spiridonov and his doctor are optimistic about it.
