On Monday, August 29, 2005 Hurricane Katrina passed east of New Orleans causing minimal damage to Tulane's Medical Center. Later that day, levees that protected the city failed and several feet of water entered the hospitals and school buildings. Emergency generators provided power for 36 hours before running out of fuel. Temperatures in the hospitals soared into the upper 90's and conditions were made intolerable by 100% humidity and backed-up sewage. For several days, faculty, residents, nurses and hospital personnel performed heroically, caring for patients in appalling conditions, hand-ventilating critically ill patients in shifts. Approximately 200 patients, and 1500 additional personnel would be evacuated on Wednesday and Thursday from a makeshift heliport on Tulane's parking garage. Current disaster plans may be inadequate should facilities be inaccessible for months because of damage or contamination. Contingency plans also need to be made should outside disaster relief be markedly delayed as was the case with Katrina.
