What would the ethical and legal principles?
legal principles are basically right of a person to survive vs. the right to make medical decisions. if the child is in a “persistive vegetative state” the parents have the right to terminate. But a lot depends on the prognosis (not diagnosis) of survival. Ethical principles are strict right to life vs right to life as a conscious human being. Again much too little detail. If the prognosis- probable outcome is a life similar to a Downs Syndrome child, maintain support. But profound retardation ie “Torch Syndrome” I personally advised to pull the cord because the child would eventually reach the maturity of a 6 month old child and die at puberty and require many thousands of dollars of medical care.
