can it cause brain damage according to the amount of time spent outside?

Question

someone on alchohol pased out in 0 degree weather for 3 hours

Answer 1

The concern would be severe hypothermia. Alcohol consumption speeds the loss of body heat because it dilates blood vessels in the periphery. Hypothermia can lead to brain damage. So yes, brain damage can be caused by passing out drunk in very cold temperatures and becoming hypothermic. That's actually a relatively common situation.

Answer 2

Brain damage would be the most dangerous consequence of such situation. 3 hours at 0 degrees environment and unconscious under alcohol effects, would be sufficient enough to cause SEVERE HYPOTHERMIA. The alcohol could also contribute in faster losing of body heat.

The possible brain damage however would depend on how low the core body temperature had gone. The clothings worn on that time got a big role to play. Heavy clothings and more especially if head and extremities coverings (hat,gloves,shoes) are worn will somehow slow down losing the body heat, so 3 hours exposure in freezing environment possibly won't cause significant damage. If body coverings are poor, then brain damage can happen after severe hypothermia which takes place if body core temperature drops below 33 °C.

While the body will try to do "protective mechanisms" to preserve core body temperature by constriction of some blood vessels, the vasodilating effects of the alcohol could make that function less effective making the losing of the body heat faster. FROSTBITE could be another consequence.

(Anyway, have your heard that lowering the body temperature up to to 33°C had been found to protect brain from injury? Reducing body temperature was believed to decrease the brain’s demand for oxygen, reduces the release of nerve-killing chemicals, suppresses inflammation, and stabilizes cell membranes. That has been recently used in medicine to protect brain of those who had cardiac arrest, stroke and the like.) - Very low temperature at longer period however can shutdown the circulation and incur severe damages even death.

Answer 3

Her suicide attempt left her suggestions disadvantaged of oxygen for an prolonged sufficient quantity of time to kill suggestions cells. it would look that she did some injury to the section that controls involuntary muscular strikes which include diaphragm contractions for this reason proscribing her respiration on her very own. finding on the point of the suggestions injury and how plenty she tries to breath on her very own while the vent is slowed or stopped my inform you if she would be able to stay or no longer. regardless of what problems she concept have been undesirable sufficient to warrant suicide her problems purely have been given a bargain worse. My inner maximum sympathies to her acquaintances and kin.

Answer 4

I would be more concerned about frost bite than alcohol at that point.
