Alcohol can defend against traumas

As it turned out, drunk and abstinent people differently react to the injuries. Scientists discovered that some amount of alcohol in blood probably decreases the risk of post-traumatic stress disorders. 
Alcohol can defend against traumas

Patients with injuries are less likely to get damage of heart and kidneys, if their blood alcohol level is elevated. To this unexpected conclusion came the scientists from the University of Illinois. “After an injury, alcoholic intoxication probably renders some defensive effect”, says Lee Friedman, the author of the research. “But we yet do not fully understand why it happens”.
To understand better this phenomenon, Friedman had researched from which sequelas after the injuries die the most people in the hospitals. He had tracked the level of alcohol in blood of patients as well. According to the results of previous researches, around 64% of all post-traumatic lethal outcomes take place by reason of specific medical sequelas. the research were included the data of 85000 with traumas, who also had been tested on the level of alcohol in the blood. Scientists were gathering data of traumatological departments of the hospitals of state Illinois of the last ten years. Children under 16 years old and patients with burns and flesh-wounds were excluded from the research. The level of alcohol in the blood varied from 0 up to 0.5%. 0.5% is the amount of alcohol which endangers the life of a person. It exceeds more than in six times the allowed level of the alcohol in United States. 

The number of patients included in the research, who died, is 3,2%. The mortality rate was much higher among patients, who had been diagnosed with post-traumatic sequelas: among those who died, at least one post-traumatic sequela was found in 43,2% of cases. However, the presence of alcohol in blood, as it turned out, is connected with less riskiness of sequelas development. Those patients had 23,5% less sequelas connected with circulatory system and 30% sequelas connected with kidneys. “Though alcohol quite quickly decomposes in an organism, defensive effect lasts much longer”, says Friedman.
He also notes that it is yet unclear whether defensive effect appears right after injury, when the alcohol is still in blood, or defense is conditioned by products of its metathesis, and also by reaction of an organism on alcohol and trauma. “Yet our data say about the decrease of sequelas of heart and kidneys, but it is necessary to carry out a lot of researches to understand how it works exactly”, adds Friedman. However, it does not mean to consider all written above as a reason to drink alcohol. The researches just began, while the adverse effect of alcohol is known for a long time.
