GHB intoxication leading to reduced consciousness is a frequent reason for ED admission, above all in young people and in the early morning at the weekend. Symptoms are more severe in patients who have taken GHB in combination with other substances of abuse.
Cannabis is the most commonly used illicit drug in Europe, and is generally regarded as having low acute toxicity. We present the findings of the first 6 months of data collection from the Euro-DEN project on presentations related to cannabis use to further understand the acute toxicity related to the use of cannabis. Data was extracted on clinical features, treatment and outcome from the Euro-DEN minimum dataset for all cases of acute recreational drug toxicity reported 1st October 2013 to 31st March 2014 for all cannabis-related presentations. Of 2198 presentations reported by 14 of the 16 Euro-DEN centres, 356 (16.2 %) involved cannabis either alone or together with other drugs/alcohol. There were 36 that involved lone use of cannabis (1.6 % of all presentations). Of the 35 non-fatal lone cannabis presentations, the most commonly reported features were neuro-behavioural (agitation/aggression 8 (22.9 %), psychosis 7 (20.0 %), anxiety 7 (20.0 %)) and vomiting 6 (17.1 %). Most patients (25, 71.4 %) received no treatment and 30 (85.7 %) were discharged/self-discharged from the ED. There was one fatality amongst these lone-cannabis cases: an 18-year-old male collapsed with an asystolic cardiac arrest whilst smoking cannabis and suffered hypoxic brain injury related to prolonged cardiac arrest. THC was detected in a urine sample taken at ED arrival; no other drugs were detected. Lone acute cannabis toxicity was typically associated with neuro-behavioural symptoms and vomiting. Although uncommon, severe toxicity including cardiovascular toxicity and death may be under-recognised, and it is important that Emergency Physicians are aware of this.
The study included 807 patients, of whom 6.7% revisited the ED within 30 days, 11.9% within 3 months and 18.9% within 1 year. The variables significantly associated with ED revisits were: presence of clinical manifestations directly related to cocaine (p < 0.05), ED attendance on a working day (p < 0.05), history of ED visits related with the consumption of alcohol (p < 0.001) or drugs (p < 0.001), and the need for urgent consultation with a psychiatrist (p < 0.001), although only the last four were independent predictors in multivariate analysis. We derived a score based on these variables to predict risk of revisits (MARRIED-score, ranging from 0 to 400 points), which had a reasonably good predictive value for revisit (area under ROC of 0.75; 95% CI 0.71-0.79).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
