Critical injury treatment in the hardest-hit areas after a great earthquake was retrospectively analyzed to determine how best to reduce mortality and disability and increase the rehabilitation rate through postquake medical relief. ⋯ The medical relief model of "supervising body helping subordinate unit, severely stricken areas assisting hardest-hit areas, least-hit areas supporting both hardest-hit and severely stricken areas, and self help and mutual assistance applied between hardest-hit areas" was roughly established for injured from severely stricken areas after the Wenchuan Earthquake. The "four-centralization" treatment principle, which referred to concentrating patients, experts, resources and treatment for those injured in critical condition effectively reduced the mortality from 15.06% to 2.9%. Timely, scientific, and standard on-site triage and postmedical transfer guided by accurate injury information determine rescue effect for the injured, while there is large space to fulfill as for treatment for critical diseases among the hardest-hit areas under extreme conditions after the Wenchuan earthquake.
