ABSTRACT
Objective To explore the changes of blood alcohol concentration (BAC) and its influencing factors in alcohol consumption, and establish a mathematical model of BAC metabolism. Methods The BAC was measured by using the gas chromatograph and the internal standard curve method, and the data was analyzed by SPSS20.0 and R and the mathematical model was established. Results On average women BAC elimination rate is 9.54mg/100mL/h, the average male BAC elimination rate is 12.19mg/100mL/h, women elimination rate less than men, and BAC elimination rate is related to gender of medium and related to the weight of strong, has nothing to do with age. According to the results of the mixed effects model, the mixed effect model can predict the BAC accurately, the mean absolute error (MAE) is 1.60mg/100mL, and the data is analyzed by the decision tree method, and MAE is 9.99mg/100mL. Conclusion BAC elimination rate was associated with sex and weight after drinking, and the random-effect mixing model could be accurately inferred by time, alcohol consumption, sex and weight.
ABSTRACT
This study was conducted to assess the trends of drunk driving offences in Mauritius, and the relationship with motor vehicle accidents. It is well known that driving under the influence of alcohol increases the risk of motor vehicle accidents. Data obtained from police road safety unit (1999–2001) and forensic science laboratory (1992–2000) were analyzed. More than 85% of drunk drivers had BAC above 0.08%. In 2003, the permissible blood alcohol concentration (BAC) limit had been lowered from 0.08 to 0.05. This article provides a summary of the evidence regarding the benefits of reducing the blood alcohol concentration (BAC) for driving. Although moderate alcohol intake (20 grams ethanol; two standard drinks or less) may not violate BAC laws, it still carries significant risk of motor-vehicle accidents.
ABSTRACT
A 48 years old man was sent to hospital through emergency room immediately after head injuries. He was arrived at hospital being dead and autopsy was done sixty hours later after insult. Multiple skull fractures and brain parenchymal contusions, subarachnoid hemorrhage, stem hemorrhage were noted, and these injuries were considering as a cause of death. Interestingly, blood alcohol concentration (BAC) using cardiac blood was very high (0.738%) in this case. Here in, we report abnormally high BAC in heart blood which is not a cause of death and we review the general aspects about alcohol concentration interpretation.
