When I was about 11 years I was involved in a drowning accident in Cancun wherein a drain cover was left of the bottom of a large hot tub. I was pulled onto the drain on account of the suction and spent nearly 5 minutes under hot water. My vocal cords collapsed before I passed out due to my efforts to avoid inhaling the water. I am wondering what kind of possible long-term effects that amount of time without air under hot water would have on the developing brain. Thanks for the help!
