Objective: To describe the clinical features of gamma-hydroxybutyrate (GHB) and gamma-butyrolactone (GBL) toxicity. Methods: Retrospective case-study of 65 GHB and GBL intoxications seen in an urban emergency department. Results: 63% of intoxications occurred in male patients. The median age was 24 years (range 16-41 years). 65% co-ingested alcohol or illicit drugs, mostly MDMA and cocaine. 83% presented with coma. The mean +/- S.D. time to regain consciousness among comatose patients was 111 +/- 61 min and was significantly longer in patients who co-abused illicit drugs such as cocaine or MDMA (155 +/- 60 min). Bradycardia occurred in 38%, hypotension in 6% and hypotherinia in 48%. Agitation was observed in 17% of all patients and was significantly more frequent in patients with alcohol co-use (29%). Vomiting occurred in 31% of all patients and tended to be more frequent in patients who co-used alcohol (39%). Management of GHB and GBL overdose was supportive. Four patients needed admission to an intensive care unit for mechanical ventilation (6%). Conclusions: Overdosing of GHB and GBL frequently results in non-reactive coma reflecting the severity of poisoning. Multiple drug use is common and significantly influences the clinical presentation. (c) 2005 Elsevier Ireland Ltd. All rights reserved.
