In the last couple of months, I recently heard a news story about the "Baby Frozen for Four Days". I don't know what it is, perhaps it's the suspense author in me, but I immediately began to imagine those that have had their heads disconnected from their body and frozen until a point in time comes where they can be attached to another disease free body.
But I digress. Instead, I'll keep the vision of Hans Solo in my mind.
Therapeutic hypothermia is actually a reasonable therapy to consider when the medical staff is concerned about potential brain damage.
But to say the patient is frozen is a little bit of a misnomer. If the tissue were truly frozen it would crystallize and be damaged-- this would not benefit the patient.
Instead, the body temperature is dropped to around 33 degrees Celsius or 91.4 degrees Fahrenheit. Normal body temperature is 37 degrees Celsius or 98.6. Next post will discuss how this might be accomplished.
Generally, therapeutic hypothermia is used when there is a concern for brain injury, usually after an anoxic event, which means the patient potentially suffered from a lack of oxygen.
Common situations where this could occur would be during birth (for infants) and after cardiac arrest (for adults) which is currently how the therapy is employed. It came out recently to consider therapeutic hypothermia in instances of pediatric arrest though it's not widely employed at this time.
The reason therapeutic hypothermia is effective is that it slows brain metabolism and protects brain tissue from oxygen free radicals which are release during tissue injury.
All very interesting.
So keep therapeutic hypothermia in mind for use in fiction after a patient suffers cardiac arrest as I did in my recently released novel Peril-- it will definitely add to the tension.
