Sudden unexpected death in infancy

: Unexpected death in infancy. Sudden unexpected death in infancy (SUDI) is an entity that, after a thorough investigation, includes unexplained deaths and deaths for which a cause is found. Although the number of SUDI fell sharply after the "Back to Sleep" campaign in the 1990s, it currently accounts for nearly 500 deaths per year in France. In 2007, the Haute Autorite de sante issued guidelines to specify the missions and the methods of cooperation of the various care professionals in case of SUDI. The pre-hospital emergency team has a vital role in gathering information at home. Post-mortem investigations and care of the child's relatives should continue in a SUDI Reference Center. The purpose of these guidelines is a better understanding of the causes of death for improved prevention.
