A wide range of resuscitation techniques, blood transfusions, potent drugs, machines (heart, lung, kidney) and other supports are brought into operation to save the live of a patient, and even to revive a patient already dead by some criteria. In terminal and geriatric cases, these methods are so effective that life of a kind may be prolonged almost indefinitely, however limited the existence the patient then experiences. Medical techniques may also be used to maintain life in children born with severe physical deficiencies, including lack of a brain. Conditions such as encephalocele or anencephaly, in which the brain is severely damaged or almost completely lacking, are such that the likelihood that the child would be able to live independently in society without continuous care are negligible. Such children are completely unresponsive and unaware of their surroundings.
An extreme example is the case of a women in the USA who had placed on life support (although comatose) from 1983 to 1989 at the cost of millions of dollars. In 1990 the Supreme Court ruled that no one had any right to terminate the life support facilities. In 1993 concern was expressed in the USA at the cost of $240,000 per year required to support a child suffering from an encephalocele, with a cumulative cost to that point of $500,000, at a time when other children were denied medical treatment for lack of funding.
