Dr. Michael Sabom is a cardiologist whose latest book,
Light and Death, includes a detailed medical and scientific analysis of an amazing near-death experience of a woman named
Pam Reynolds.
She underwent a rare operation to remove a giant
basilar artery aneurysm in her brain that threatened her life. The size and location of the aneurysm, however, precluded its safe removal using the standard neuro-surgical techniques.
She was referred to a
doctor who had pioneered a daring surgical procedure known as
hypothermic cardiac arrest. It allowed Pam's aneurysm to be excised with a reasonable chance of success. This operation, nicknamed "standstill" by the doctors who perform it, required that Pam's body temperature be lowered to 60 degrees, her heartbeat and breathing stopped, her brain waves flattened, and the blood drained from her head.
In everyday terms, she was put to death. After removing the aneurysm, she was restored to life. During the time that Pam was in standstill, she experienced a NDE. Her remarkably detailed veridical out-of-body observations during her surgery were later verified to be very accurate. This case is considered to be one of the strongest cases of veridical evidence in NDE research because of her ability to describe the unique surgical instruments and procedures used and her ability to describe in detail these events while she was clinically and brain dead.
When all of Pam's vital signs were stopped, the doctor turned on a surgical saw and began to cut through Pam's skull. While this was going on, Pam reported that she felt herself "pop" outside her body and hover above the operating table. Then she watched the doctors working on her lifeless body for awhile. From her out-of-body position, she observed the doctor sawing into her skull with what looked to her like an electric toothbrush.
Pam heard and reported later what the nurses in the operating room had said and exactly what was happening during the operation. At this time, every monitor attached to Pam's body registered "no life" whatsoever. At some point, Pam's consciousness floated out of the operating room and traveled down a tunnel which had a light at the end of it where her deceased relatives and friends were waiting including her long-dead grandmother. Pam's NDE ended when her deceased uncle led her back to her body for her to reentered it. Pam compared the feeling of reentering her dead body to "plunging into a pool of ice."
For practical purposes outside the world of academic debate, three clinical tests commonly determine brain death. First, a standard electroencephalogram, or EEG, measures brain-wave activity. A "flat" EEG denotes non-function of the cerebral cortex – the outer shell of the cerebrum. Second, auditory evoked potentials, similar to those [clicks] elicited by the ear speakers in Pam's surgery, measure brain-stem viability. Absence of these potentials indicates non-function of the brain stem. And third, documentation of no blood flow to the brain is a marker for a generalized absence of brain function.
