Coma

In medicine, coma (from the Greek κῶμα koma, meaning "deep sleep") is a state of unconsciousness in which a person: cannot be awakened; fails to respond normally to painful stimuli, light, or sound; lacks a normal wake-sleep cycle; and does not initiate voluntary actions. A person in a state of coma is described as being comatose. Typically, a distinction is made in the medical community between a coma and a medically induced coma, the former is generally understood to be a result of circumstances beyond the control of the medical community, while the latter is generally understood to be a means by which medical professionals may allow a patient's injuries to heal in a controlled environment.

A comatose person exhibits a complete absence of wakefulness and is unable to consciously feel, speak, hear, or move. For a patient to maintain consciousness, two important neurological components must function. The first is the cerebral cortex—the gray matter that forms the outer layer of the brain. The other is a structure located in the brainstem, called reticular activating system (RAS). Injury to either or both of these components is sufficient to cause a patient to experience a coma. The cerebral cortex is a group of tight, dense, "gray matter" composed of the nuclei of the neurons whose axons then form the "white matter", and is responsible for perception, relay of the sensory input (sensation) via the thalamic pathway, and many other neurological functions, including complex thinking.

Coma (novel)

Coma is Robin Cook's first major published novel, published by Signet Book in 1977.Coma was preceded in 1973 by Cook's lesser known novel, The Year of the Intern (also published by Signet Book).

Synopsis

Susan Wheeler is an attractive, 23-year-old third-year medical student working as a trainee at Boston Memorial Hospital. Susan, along with four other students—George, Harvey, Geoffrey, and Paul—takes rounds in surgery rooms and ICUs making post-treatment notations on the health of patients. Mark Bellows, a surgery resident in the hospital, is the instructor and supervisor of this group.

The book is a journey into the inner workings of a hospital. As these students complete their three-month surgical rotation, the dilemmas and problems faced by a woman in a so-called "man's" profession are also highlighted.

It comes to Susan's attention that two patients, Nancy Greenly and Sean Berman, mysteriously went into comas immediately after their operations. These incidents were attributed to complications due to anesthesia. Nancy Greenly became comatose when her brain did not receive sufficient oxygen during surgery. Similarly, Sean Berman, a young man in his 30s in good physical condition, underwent a scheduled knee operation. Despite the operation's success, Sean failed to regain consciousness. Medically, the odds for such occurrences are one in 100,000; however, such odds seemed resolutely higher at the Boston Memorial Hospital.
