Severe cognitive disability, medically complex children and long-term ventilation.

Children with complex medical conditions including those with severe intellectual disability are living longer. For some, support with medical technology such as Long-Term Ventilation can prolong their lives further. Such technological supports can have significant implications for the child and her family and consume considerable resources though they can also offer real benefits. Sometimes clinicians question whether children with very severe cognitive impairments should have their life prolonged by technology, though they would be prepared to provide the same treatment in equivalent cases without cognitive disability. We describe and analyse four ways in which this view might be justified. Although it could be claimed that children with severe cognitive disability have lives that are not worth living, in most cases this view can and should be rejected. However, the burdens of life-prolonging technology may outweigh the benefits of such treatment either in the present or in the future. Consequently it might not be in their interests to provide such technology, or to ensure that it is provided as part of a time-limited trial. We also consider circumstances where medical technology could offer modest benefits to an individual, but resources are scarce. In the face of resource imitation, treatment may be prioritised to children who stand to benefit the most. This may in some circumstances, justify selectively withholding treatment from some medically complex children.
