OBE during surgery involving deep hypothermic cardiocirculatory arrest.

Dunno how this letter by Mario Beauregard which was published in Resuscitation during 2011 got past me... but I've not seen it mentioned elsewhere. So posting it here. Retrospective report from surgery 3 years prior, and not possible to say when during the procedure the OBE occurred... but interesting never-the-less.

We recently conducted a retrospective study in patients who underwent deep hypothermic  cardiocirculatory arrest (DHCA) at Hôpital Sacré-Coeur (a research hospital affiliated with the Université de Montréal) between 2005 and 2010. This surgical procedure was employed in these patients to repair aortic defects. The main objective of the study was to estimate the prevalence of conscious mental events during DHCA. A total of 33 patients returned completed questionnaires (70 were sent). Three patients (9%) reported conscious mental activity. The three patients were interviewed following the receipt of the completed questionnaires.

The case of one patient is particularly worth reporting. This patient, J.S., was 31 weeks pregnant when, on October 26, 2008, she woke up feeling short of breath and weak (J.S. was then 31-yearold). She was transported to Hôpital Sacré-Coeur by ambulance.

Using transoesophagial echocardiography, physicians found out that she was suffering from an ascending aortic dissection. 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.

At one point during surgery, J.S. claims to have had an out-ofbody experience (OBE). From a vantage point outside her physical body, she apparently “saw” a nurse passing surgical instruments to the cardiothoracic surgeon. She also perceived anesthesia and echography machines located behind her head. We were able to verify that the descriptions she provided of the nurse and the machines were accurate (this was confirmed by the cardiothoracic surgeon who operated upon her). Furthermore, in the OBE state J.S. reported feelings of peace and joy, and seeing a bright light.

Reports of independently corroborated veridical OBE perception during cardiac arrest have previously been published (Van Lommel et. al. 2002). Here it cannot be determined with certainty whether the subjective experience reported by J.S. occurred precisely during the cardiocirculatory arrest (which lasted for 15 min). Nonetheless, the tantalizing case of J.S. raises a number of perplexing questions.
