Abstract :

The technique of brain protection has started in 2007 after the presentation of the method proposed by a neurologist from Cornell University NY City by evaporation of perfluorocarbon in fossa nasalis. This method was studied on a pig model at the Weil Institute of Cardiac Care Medicine (WICCM) in Rancho Mirage California. I immediately suspected that it was possible to obtain the same result, faster and stronger by expansion of highly compressed gas. After several experiments and discussions with experts it was found that carbon dioxide was the most appropriate gas. This was confirmed on a pig model able to reproduce the work performed at WICCM. It was during this experiment, that my wife experienced sudden cardiac death beside me while watching TV in June 2011. She had no femoral pulse which prompted to perform chest compression. Because of my work on the Fulguration procedure 30 years before, I had a defibrillator in the basement of my house. The third shock proved successful but without return to consciousness. I then used the prototype of a bottle filled with compressed CO2 used for my experiments. In the following days in La Salp�ªtri�¨re hospital she had 4 more episodes of VF explained by an old asymptomatic myocardial infarction seen on coronarography. She was able to awake after 6 days of coma and recovered completely without absolutely no brain deficit despite 6 minutes of no flow. She subsequently had an ICD and had two other episodes of syncope in the street before proper pharmacologic therapy. She never had release of troponin demonstrating that the arrhythmia was a pure electric phenomenon. The work made on the pig model suggested that it was possible to cool the brain by the mouth as well as the fossa nasalis. This opened the possibility to create a new device with a CO2 bottle on top of a tripod with injector in the mouth and make usable in stroke, brain trauma and children hyperthermia. The final device is so simple that it can be used by everybody. The next step is to perform a pilot study of two subgroups of cooled and non-cooled patients.
