Anaesthesia and Prader-Willi syndrome.

A review of a case series of sixteen anaesthetics in eight cases was undertaken to determine whether children with Prader-Willi syndrome present particular problems to the anaesthetist. Children in an early stage of the condition who are below their centile for weight present no specific problems. Children who are heavier than 97th centile weight have problems associated with their obesity: difficult intravenous access and sleep apnoea. Scoliosis was noted in both groups and was not associated with problems after minor surgery.
