[The response of the intensive care units during the influenza A H1N1 pandemic: the experience in Chiapas, Mexico].

Respiratory virus epidemics had highlighted the importance of the Intensive Care Unit (ICU) to save life of severe cases. ICU functioning and outcomes depends on infrastructure and trained healthcare personnel. In Chiapas, a Southern state in Mexico,an area to care for severe H1N1 cases on respiratory distress during the second H1N1-2009 outbreak, had to be habilitated.This had to be done without sufficient equipment and ICU un-experienced healthcare workers. It was possible to improve its performance through training and standardizing attention care processes for critically ill patients. In preparation for the next pandemic it is essential to designate hospitals with preexistent ICU where to refer severe cases and avoid improvisations.The experience in Chiapas showed that standardization of medical care processes are clue and in case of an overwhelming emergency it is possible to habilitate an ICU although it is imperative to take advantage from installed facilities in each city with the official authority.
