Suspended animation for surgery to convert near certain death to 90% survival

Previously we discussed the work of Lance Becker from his Singularity Summit talk on using supercooling for surgery.

The UK Telegraph reports on surgeons pioneering the method of inducing extreme hypothermia in trauma patients so that their bodies shut down entirely during major surgery, giving doctors more time to perform operations.

* If you drop the body's core temperature and brain temperature down to 15 degrees C or 10 degrees C you are talking about 60 minutes and even 190 minutes of protection.

* By cooling rapidly in this fashion we can convert almost certain death into a 90 per cent survival rate

* Pump are connected to the major blood vessels around the heart to remove the warm blood in the body and replace it with cold saline solution.

* the body cools by around 2 degrees C every minute, rapidly causing the body's tissues to shut down (previous techniques took 8 hours for 3 degrees of cooling)


Patients who have undergone this type of surgery suffer no long term impairment to their brain function.

Around the world nearly 6 million people die each year from injuries (16000 each day)

In the USA, about 400 people die each day from injuries and 200 sustain long term disabilities. The world injury death total is about 11% of deaths from any cause. Injuries are the leading cause of death in the first half of human life span.
