[Disasters. Assistance plans].

A disaster is defined as a unseasonable event that provoke such an amount of victims that the health care capacity of the community is exceeded. The aim of this paper is to review the health attention during an emergency period, whose pre-hospital and hospital services are inherent to critical care medicine. The reduction in victim's morbidity and mortality depends on the opportuneness and efficacy of pre-hospital care. Trained personnel is required to establish command posts, perform the rescue, categorize seriousness of victims to receive priority health care and transport to better equipped health centers. At the hospitals an emergency team must elaborate, publish and periodically review emergency care plans and eventually coordinate actions with other community organizations. The diverse phases of the plan must be specified, including preparatives, alerting of involved services, victim care, and reestablishment of normal duties when the emergency situation ceases. As complement, the hospital must have security and evacuation plans to face own emergency situations such as fires, explosions and inundations.
