One of the most neglected aspects of cryonics is that its procedures, and the research to support them, can have important practical applications in mainstream fields such as organ preservation and emergency medicine. Contrary to popular opinion, cryonics does not just involve an optimistic extrapolation of existing science but can set the standard for these disciplines. As a matter of fact, that is exactly what cryonics, and cryonics associated research, has been doing over the last 25 years.
The most striking example is the progress in vitrification as an alternative for conventional cryopreservation. Although the idea of eliminating ice formation at low subzero temperatures has been discussed since the beginning of cryobiology, vitrification as a serious research agenda was largely driven by the demand for ice-free preservation of the human brain. Over the last decades this research has culminated in the development of the least toxic vitrification agent to date, 21st Century Medicine’s M22.
The contributions of cryonics to mainstream science and medical practice are not confined to cryobiology. Researchers Jerry Leaf and Mike Darwin made impressive progress in the formulation of bloodless whole body organ preservation solutions to resuscitate dogs from ultraprofound hypothermic temperatures, an intervention that is increasingly being recognized as essential to stabilize trauma victims. In the mid 1990s, Mike Darwin and Steve Harris conceived and developed the idea of using liquid breathing with perfluorocarbons as a method to induce rapid hypothermia. They further validated a multi-modal medications protocol to resuscitate dogs from up to 17 minutes of normothermic cardiac arrest without neurological damage.
Although progress has slowed considerably in the non-cryobiology research areas over the last 10 years, it is encouraging to observe that some of the procedures that are routine in cryonics stabilization protocol are starting to catch on in mainstream emergency medicine practice as well. For example, contemporary cryonics stabilization protocol has been strongly shaped by the idea that the best strategy to limit brain injury after cardiac arrest is to combine a number of different interventions: cardiopulmonary support, induction of hypothermia, and administration of circulation-supporting and neuroprotective medications.
It is therefore very encouraging to learn that the Wake County EMS group in North Carolina has achieved impressive results in treating out-of-hospital cardiac arrest victims using a protocol that closely follows elements of current cryonics stabilization protocol. Systematic implementation of immediate induction of hypothermia, continuous compression CPR, and the use of an impedance threshold device (ResQPOD) produced an almost 400% improvement in survival and vast improvements in neurological outcome. A PowerPoint presentation about their experience and protocols are available at their website.
Such real world outcomes do not only inspire confidence in the procedures cryonics organizations can use to protect patients from brain damage after cardiac arrest, it should also serve as a wake-up call to relaunch an aggressive research agenda to push the limits of hypothermic and normothermic resuscitation. In absence of this, it will only be a matter of time before cryonics activists can no longer claim that “we did it first.”
