A. In Young Children.—This may be in the new-born or older children.
In the new-born exposure to cold soon causes death, as warmth is essential to the life of the young being. The length of time necessary to a fatal issue is modified by several conditions. In the immature or prematurely born infant the resisting power is much less than in the child born at full term and otherwise healthy. In cases of suspected infanticide by exposure the question of the maturity of the child at birth is to be decided. Careful examination of the place in which the body was discovered should be made as to its lack of warmth; and the degree of external cold at the time of probable exposure should be recorded. The circumstances as to whether the exposure was inadvertent or accidental, as in cases of premature or unexpected delivery, or whether from intentional and deliberate purpose or from culpable neglect, should be carefully considered. The post-mortem examination should decide whether the appearances and conditions of the body are those peculiar to death from cold (Case 2).
Death may occur from culpably careless exposure to cold, as a contributory if not as a direct cause, in such conditions of enfeeblement. Criminal neglect to provide medical attendance, food, and other essentials has been proven in some cases of the so-called “faith cure” or “prayer cure.” Exposure may be resorted to with deliberate homicidal intent. It may, in some cases of death, become an important legal question to decide whether a studied and persistent neglect of this nature may not have been followed, with the purpose of getting rid of a troublesome care (Cases 2 and 3).
B. Exposure of the injured or wounded, thereby inducing some grave condition or complication which under proper care would have been avoided, may raise an important question in injuries inflicted by another, with or without criminal intent. It is undeniable that serious or fatal results may follow a slight wound, otherwise trivial, where the injured person was subjected, accidentally or intentionally, to extreme cold for a considerable period. While such cases are comparatively rare, they may demand investigation.
C. Exposure of the Insane.—While it must be admitted that the insane subject is usually indifferent to matters of temperature, death from exposure to cold may call for special examination. Carelessness, incompetence, or wilful neglect on the part of nurses or keepers of insane hospitals, or deliberate criminal intent in such or others having the care of or an interest in the death of an insane person may lead to a judicial inquiry.
Sudden death has been reported as occurring, in several cases, after the ingestion of large quantities of cold water when the person was greatly heated. It is somewhat difficult to explain all such cases reported on a single line of causation. Some observers have attributed death to syncope or asthenia by the shock produced, in the sudden effect of the cold upon the sympathetic nervous system inducing heart failure. This seems the most natural explanation.
Others consider the causative factor to be the formation of thromboses in the capillaries of the brain, lungs, and other organs, inducing active and obstructive congestions causing death by apnœa or coma. Others regard these cases as similar to “heat apoplexy.”
