The Relationship

The relationship between the blood alcohol concentration and the urine alcohol concentration was studied in 109 routine coroner's autopsies. Although the average ratio for urine alcohol concentration to blood alcohol concentration lay close to the ratio of 4:3 quoted in the literature, the actual ratios determined were widely scattered around this value. Thus the use of this simple ratio to estimate the blood alcohol concentration from the urine alcohol concentration at post-mortem was unreliable. An equation determined by employing linear regression analysis was similarly unhelpful in enabling one to derive a precise value for the blood alcohol concentration from a given urine alcohol concentration. It was concluded that the main value in determining the urine alcohol concentration at autopsy was to exclude the possibility of the alcohol present in the blood sample having been generated during the post-mortem interval.

Post Mortem Findings

The resident population in the Geelong coronial district is approximately 250 000 persons and has almost doubled since 1957. The autopsy rate for all persons dying by accident is virtually 100 per cent, with specimens being taken for blood alcohol concentration on all such deaths. The ‘Geelong Experience’ concerning alcohol and drowning is based on the post-mortem findings and the history of the events which surrounded 238 fatal submersions during the 24-year period, 1957 to 1980. Males greatly predominated over females and 139 drownings occurred in males aged 15 years and older. No female had an autopsy blood alcohol concentration (BAC) greater than 0.08 per cent (18 mmol/L) whereas such concentrations were present at autopsy in 35 per cent of all drowned males aged 15 years and older. Of the deceased males in the 30 to 64 years age group, 45 per cent of those submersed while swimming or surfing and 75 per cent of those falling or slipping into water had autopsy BACs greater than 0.150 per cent (33 mmol/L). Of these latter males, 8 (that is, 33 per cent) had autopsy BACs greater than 0.25 per cent (55 mmol/L).

Considering the growing number of requests from the criminal investigations authorities addressed to the institutions of legal medicine, testing of blood alcohol concentration both in the living person and in the corpse, we believe that a presentation of the two methods which are used in our country, is a topic of interest at present. The purpose of this article is to provide the reader with the technical details on how blodd alcohol concentration is realised by means of the gas chromatographic method and the classical one, (Cordebard modified by D. Banciu and I. Droc) respectively. Another purpose of this article is to also show, in a comparative way, the elements that make the gas chromatographic method superior to the former one.

And Performance

There is a large body of research that documents the impairing effect of alcohol on driving behavior and performance. Some of the most significant alcohol influence seems to occur in divided attention situations when the driver must simultaneously attend to several aspects of the driving task. This paper describes a driving simulator study of the effect of a low alcohol dose, .055 BAC (blood alcohol concentration %/wt), on divided attention performance. The simulation was mechanized on a PC and presented visual and auditory feedback in a truck cab surround. Subjects were required to control speed and steering on a rural two lane road while attending to a peripheral secondary task. The subject population was composed of 33 heavy equipment operators who were tested during both placebo and drinking sessions. Multivariate Analysis of Variance showed a significant and practical alcohol effect on a range of variables in the divided attention driving task.

Driving Scenario

This article describes a drink-driving scenario where a woman was apprehended for driving under the influence (DUI) with a blood alcohol concentration (BAC) of 256mg/dl1 The correctness of this result was vigorously challenged by a medical expert witness for the defence, who was actually a specialist in alcohol diseases. Despite reanalysis to confirm the BAC as well as a DNA profile to prove the identity of the blood specimen, the woman was acquitted of the charge of drunk driving by the lower court. However, she was subsequently found guilty in the High Court of Appeals with a unanimous decision and sentenced to four weeks imprisonment. This case report illustrates some of the problems surrounding the use of expert medical evidence by the defence to challenge the validity of the prosecution evidence based solely on a suspect's BAC. In situations such as these, an expert witness should be called by the prosecution to clarify and, if necessary, rebut medical and/or scientific opinions that might mislead the court and influence the outcome of the trial.
