Near Death Experiences
Is there a life after death?

Mental activity during
hypothermic cardiac arrest?

©G.M. Woerlee, 2005–2017


A letter from Dr. Mario Beauregard, author of the book The Spiritual Brain was published in the January 2012 edition of the respected international medical journal called Resuscitation. Its content has been prominently featured in the website of the International Association for Near-Death Studies as further proof of the immaterial reality of the nature of experiences undergone during near-death experiences (NDEs). The letter is entitled, "Conscious mental activity during a deep hypothermic cardiocirculatory arrest?", and can be downloaded by clicking on this link. Below is a summary of the letter.

"Conscious mental activity during a deep hypothermic cardiocirculatory arrest?" describes the preliminary results of a retrospective questionnaire study of 70 patients who underwent deep hypothermic cardiac arrest for surgery of the aorta at the Sacre Coeur Hospital in Montreal between 2005-2010. (Deep hypothermic cardiac arrest is the same procedure as was undergone by Pam Reynolds during 1991.) 33 persons returned completed questionnaires, and of these, 3 patients reported periods of awareness during the procedure. One of these persons was a woman when 31 weeks pregnant during 2008 when she developed a life-threatening aortic dissection. She underwent an caesarean section to deliver a baby boy, and was subsequently taken to the surgical operating theater where she was put under general anesthesia to undergo an operation on her aorta under deep hypothermic cardiac arrest. Sometime during the operation she underwent an out-of-body experience during which she made apparently veridical observations (verified only by the cardiothoracic surgeon), experienced feelings of peace and joy, as well as seeing a bright light. It was uncertain whether this experience occurred during de period of hypothermic cardiac arrest.

Regrettably, the quality of the journal seems to be no guarantee for scientific accuracy in the case of this truly misleading article. It is not only misleading, but raises a considerable number of questions which regrettably go unanswered in this letter. I will begin with the most misleadingly inaccurate aspect of the this letter, where Mario Beauregard states the following:

During the last decade, prospective studies conducted in the Netherlands, United Kingdom, and United States have revealed that approximately 15% of cardiac arrest survivors report conscious mental activity while their hearts are stopped.

This statement reveals that Mario Beauregard ignores, or is ignorant of more than 50 years of cardiological research. Consciousness is possible without heartbeat. There are several well-researched situations proving just this fact. Consciousness without any heartbeat at all occurs under the following situations:

The anesthetic literature is awash with a plethora of studies on the incidence of awareness (consciousness) occurring during general anesthesia. One of the better reviews of the cchance of awakening during general anesthesia for various operations was published by Dr. Ghoneim during 1992 (Ghoneim 1992). People undergoing caesarean section have a 7-28% chance, and those undergoing cardiac surgery have a 23% chance of experiencing awareness during general anesthesia (page 283 in Ghoneim 1992). Although this article was published during 1992, the incidence of awareness during general anesthesia for these operations has not changed significantly, although the drugs used have changed, and the awareness that it can occur is now always present in the minds of all anesthesiologists. The first reaction of many people is that awareness during anesthesia is ALWAYS horrifying and painful. A prospective study of more than 19,000 anesthetics published by Dr. Sebel and his colleagues during 2004 (Sebel, et al, 2004), revealed something very different. Dr. Sebel reported that of the patients who experienced awareness during general anesthesia:

This woman was in a life-threatening and unstable circulatory situation when she underwent her underwent a caesarean section. One of the unanswered questions in the article of Mario Beauregard is the nature of the anesthetic used for the caesarean section. All we read in his letter is that this woman whose initials are given as J.S.:

J.S. first underwent an emergency caesarean section. After having successfully delivered a baby boy, she was then transferred to a surgery room to undergo the replacement of the ascending aorta. She did not see or talk to the members of the surgical team, and it was not possible for her to see the machines behind the head section of the operating table, as she was wheeled into the operating room. J.S. was given general anesthesia and her eyes were taped shut.

This is a very strange passage.

These are some of the reasons why "Conscious mental activity during a deep hypothermic cardiocirculatory arrest?" is a very strange and misleading report. This brings us to the matter of her period odf awareness while on cardiac bypass. There are several reasons why people on cardiac bypass have a high chance of developing awareness. In the case of the woman reported by Mario Beauregard, we read nothing about the nature of the anesthetic. In fact, he ignores the anesthetic aspect entirely, while the nature of the anesthetic determines that chance of awareness. Again, another very curious and strange aspect of this letter. So what are the factors making awareness likely during cardiac bypass?

As to the matter of the out-of-body experience (OBE). It is being increasingly realized that OBEs are manifestations of abnormal displacement of body image induced by a multitude of factors. In fact the study of OBEs is the subject of considerable international standard neurological research (see Brugger, et al, 2009). Drugs used for anesthesia are all known to induce OBEs as well as the feelings of peace and joy described by Mario Beauregard (see Illusory Souls).

In conclusion, the letter "Conscious mental activity during a deep hypothermic cardiocirculatory arrest?" in no way supports the belief in a separable immaterial consciousness. Mario Beauregard implies this possibility in a roundabout and tendentious manner, but the facts as reported in this letter raise more questions than answers. It would be interesting to see the actual operation reports, to learn the locations of the operating theaters, and especially interesting to see the anesthetic reports to determine whether consciousness was possible. Until such information is available, this report remains no more than described, misleading, suggestive, and providing too little information to form any conclusions.
