[00:00:00]The scientists who used hypothermia on comatose patients, 1950 Sweden. Doctors chilled unconscious patients to near freezing temperatures.

[00:00:08]Their goal, slow brain damage after cardiac arrest. Blankets of ice were packed tightly around the body. Body temperature dropped to 28° nearly freezing.

[00:00:18]Heart rate and metabolism slowed dramatically. Some patients revived with minimal brain injury. Others suffered dangerous complications and infections.

[00:00:27]Medical staff monitored vital signs constantly.

[00:00:30]Resuscitation was performed using heated air and fluids. Results [music] were published in Swedish medical journals.

[00:00:36]This technique inspired future therapeutic hypothermia protocols.

[00:00:40]Later methods improved safety and patient outcomes.

[00:00:44]The experiment proved brain protection was possible. Not all patients survived the risky procedure. Hypothermia is now standard in modern emergency medicine.

[00:00:53]Original trials were controversial and faced criticism. Swedish doctors changed the the course of neurocritical care.

[00:01:00]Freezing the body to save the brain, unexpected science, and sometimes survival means turning up the cold. The scientists who used hypothermia on comatose patients.
