NEW ORLEANS (AP) -- It took five mighty shocks to get Cynthia Crawford’s heart to start beating again after she collapsed at Ochsner Clinic a few weeks ago. A dramatic rescue, to be sure, yet it was routine care she could have had at any hospital. What came next, though, was not. As she lay unconscious, barely clinging to life, doctors placed her in an inflatable cocoon-like pool that sprayed her naked body with hundreds of icy cold jets of water, plunging her into hypothermia.
