A toddler's brain damage has been reversed over a year after near drowning


Physicians used a series of oxygen treatments, like hyperbaric oxygen therapy, to significantly reverse the 2-year-old's brain damage after she was in the water for 15 minutes.

To "wake up" her brain, doctors gave Carlson oxygen at a pressure higher than the general atmospheric pressure — increasing the amount of oxygen in her blood and repairing her damaged tissue in a sealed, pressurized hyperbaric chamber.

"The startling regrowth of tissue in this case occurred because we were able to intervene early in a growing child, before long-term tissue degeneration," hyperbaric specialist Paul Harch from LSU Health New Orleans said in the case report published by Medical Gas Research.
