Unlabelled:
The depressing effects on the nervous central system (NCS) induced by benzodiazepines and ethanol are similar. The complications are rare in the benzodiazepine poisoning, but are a lot more frequent in association with other depressing drugs for the NCS (especially alcohol).
Material And Methods:
We analyzed retrospectively patients with benzodiazepine poisoning admitted in the Internal Medicine Clinic - Toxicology during 2003 - 2009.The study attempted a complex evaluation of the consequences of acute and chronic alcoholism on the evolution of acute benzodiazepinepoisoning and the description of the clinic evolution and paraclinical particularities of the patients under investigation.
Results:
343 patients with benzodiazepine poisoning were admitted, 150 were tested through measurement of alcohol level, leading to values between 1 - 415 mg/dl. Chronic alcoholism in personal pathological antecedents of the patients determined a relative risk of intoxication 1.46 times higher. The hospitalization period varied from 1 to 8 days for patients with chronic alcoholism and from 1 to 14 days for patients with acute alcoholism, a statistically important difference.
Conclusions:
During the period under investigation, from the total of patients admitted for acute benzodiazepine poisoning, 2 deaths were registered. Of the two deaths, one patient showed ethanol coingestion.
