Alcohol intake and the pattern of trauma in young adults and working aged people admitted after trauma.

AIMS: To investigate the relationship of different patterns of alcohol intake to various types of trauma. METHODS: We examined the associations of alcohol consumption in a series of 385 consecutive trauma admissions (278 men, 107 women, age range 16-49 years). Patients underwent clinical examinations, structured interviews on the amount and pattern of alcohol intake, and measurements of blood alcohol concentration (BAC). RESULTS: On admission, 51% of the patients had alcohol in their blood. Binge drinking was the predominant (78%) drinking pattern of alcohol intake. Assaults, falls and biking accidents were the most frequent causes of trauma. Dependent alcohol drinking and binge drinking were found to be significantly more common among patients with head trauma than in those with other types of trauma (77% vs 59%, OR=2.38; 95% CI 1.50 to 3.77). The OR for sustaining head injury increased sharply with increasing BAC: 1-99 mg/dl (1.24; 95% CI 0.55-2.01), 100-149 mg/dl 1.64; 95% CI 0.71-3.77), 150-199 mg/dl (3.20; 95% CI 1.57-6.53) and >199 mg/dl (9.23; 95% CI 4.79-17.79). CONCLUSIONS: Binge drinking is a major risk factor for head trauma among trauma patients. Assaults, falls and biking accidents are the commonest causes for such injuries. The relative risk for head injury markedly increases with increasing blood alcohol levels. Alcohol control measures should feature in policies aiming at the prevention of trauma-related morbidity and mortality.

Effects of head and extracranial injuries on serum protein S100B levels in trauma patients.

BACKGROUND: Serum protein S100B determinations have been recently suggested as markers of traumatic brain injury. However, little is known about the effects of extracranial injuries on S100B levels in trauma patients. METHODS: We studied 224 patients with head trauma (54 of whom also had extracranial injuries), 155 patients with various types of extracranial injuries, and 8 healthy pilots exposed to high Gz forces. The head trauma patients had either no brain injury (n = 35), mild brain injury (n = 165), or moderate to severe brain injury (n = 24). The extracranial injuries were divided into small and large injuries. Serum protein S100B levels were determined from samples taken within 6 hours after the trauma event. RESULTS: The head trauma patients had a significantly higher median S100B (0.17 microg/L) than the patients with extracranial injuries (0.07 microg/L) (p < 0.001). Serum S100B levels also correlated with the severity of brain injury (p < 0.001), the highest values occurring in the patients with moderate to severe brain injury (1.27 microg/L). However, large extracranial injuries also elevated S100B levels (0.35 microg/L), whereas small extracranial injuries in the absence of head trauma did not significantly affect S100B levels (0.07 microg/L). Above the cutoff level of 0.13 microg/L, there were 61% of the head trauma patients and 26% of those with extracranial injuries (Pearson chi test, p < 0.001). However, only 4% of the patients with purely extracranial injuries had a concentration of S100B above the cutoff level of 0.50 microg/L, whereas the head trauma patients with moderate to severe brain injury exceeded this cutoff in 67% of the cases. Exposure to high Gz forces did not influence serum S100B levels in healthy individuals. CONCLUSION: We conclude that serum S100B is a sensitive marker of brain injury, which correlates with the severity of the injury. Large extracranial injuries also elevate S100B levels. However, S100B has a high negative predictive power, and the finding of a normal S100B value shortly after trauma should thus exclude significant brain injury with a high accuracy.

Blood alcohol is the best indicator of hazardous alcohol drinking in young adults and working-age patients with trauma.

AIMS: To determine the most effective marker of hazardous alcohol drinking in trauma patients. METHODS: A prospective study of 349 trauma patients aged 16-49 years admitted into a general hospital trauma centre. Information on the amount and pattern of alcohol drinking was obtained by interview. Blood or breath alcohol concentration (BAC), serum gammaglutamyl transferase (GGT), aspartate aminotransferase (AST), carbohydrate-deficient transferrin (CDT) and the mean corpuscular volume (MCV) of erythrocytes were measured as markers of alcohol consumption. RESULTS: In this series, 8% of all trauma patients were found to be dependent drinkers, while 61% were frequent binge drinkers, 17% infrequent binge drinkers, 8% light-to-moderate drinkers and 6% nondrinkers. On admission, the BAC test was positive in 68% of the hazardous drinkers (i.e. dependent drinkers or frequent binge drinkers). Using a cut-off level of >0 mg/dl, the sensitivity and specificity of the BAC test for identifying hazardous drinking were 68% (95% confidence intervals [CI], 61-73%) and 94% (95% CI, 87-97%), respectively, and the positive predictive value was 96% (95% CI, 92-98%). GGT, MCV, CDT and AST were less accurate indicators of hazardous drinking. BAC was the least expensive marker. CONCLUSIONS: Two-thirds of trauma patients were hazardous drinkers, and blood alcohol on admission was an accurate indicator of this. BAC should be systematically used in trauma centres if patients are to be selected for an alcohol intervention.
