BRIAN NELSON, CNN ANCHOR: Doctors are closely monitoring an 8- year-old boy who still is fighting for his life after a vicious shark attack. Doctors say his reattached arm appears to be healing. Their main concern right at this moment is potential swelling of his brain. CNN's Brian Cabell is in Pensacola, Florida. And he has an update on that boy's condition -- Brian.</s>BRIAN CABELL, CNN CORRESPONDENT: Brian, it's been about four days now since the shark attack -- so far, no major setbacks. Doctors are encouraged by -- no swellings of the brain so far. No infections have set in. However, doctors are worried because he remains unconscious. They don't know exactly what kind of brain activity is taking place. In fact, they may reduce his sedation, the medication he's taking, to see if that can stimulate his brain. In any case, they say the next few days will be absolutely critical to his recovery.</s>REX NORTHUP, SACRED HEART CHILDREN'S HOSPITAL: The risk of death -- and that's literally the risk that he is in at this point in time, is still dying from this ordeal, related particularly to what we call cerebral edema or swelling of the brain, which occurs just like we are seeing swelling in his arm. We have seen swelling around the injury on the leg. He has had evidence of swelling elsewhere. Our brain, as a result of injury, will swell also.</s>CABELL: Even under the best of circumstances, doctors say a very long recovery and rehabilitation lies ahead for little Jessie -- Brian.</s>NELSON: All right, thank you, CNN's Brian Cabell in Pensacola, Florida.
