The authors reviewed case reports of patients presenting to an advanced medical assessment and resuscitation service at 15 music events over 22 days from June 2018 through March 2019 around Australia. Event size ranged from 4,000 to 57,500 participants. Events observed had a mean patient presentation rate (PPR) of 0.83% (SD = 0.59%) and mean transport to hospital rate (TTHR) of 1.89 (SD = 0.92) per 10,000. Two-hundred and twenty-one cases were reviewed and tabulated for descriptive analysis.

Lower rates of traumatic injuries were seen compared to other case reports, and minor procedures represented a minor but important part of the team’s workload. Methylenedioxymethamphetamine (MDMA) use was reported by 33.0% of patients on the day of presentation; almost one-half of these reported a co-ingestion. Patients presenting after using MDMA were more likely to have an elevated temperature. Eight percent of patients presented with temperature above 38°C. Patients with an initial temperature above 38°C were more likely to require hospitalization. On-site electrocardiograph (ECG), blood gas, ultrasound, and urinalysis were found to be useful in decision support. In total, 29.8% of patients required sedation during their encounter; 2.7% required rapid sequence induction at the event. Mean observation time was 44 minutes, with longer observation required in MDMA and hallucinogen-related presentations.

Ecstasy (MDMA) is a popular drug that can act as a selective serotonin neurotoxin in several species. The goal of the present study was to examine the relationship between ecstasy exposure and cognitive functioning after controlling for other drug use and demographic variables. Furthermore, we assessed whether gender was a moderator of the relationship between cognitive functioning and ecstasy use. Data were collected from 31 men and 34 women with a wide range of ecstasy use (17 marijuana users with no ecstasy use and 48 ecstasy users ranging from low to heavy use). Participants were interviewed and administered a battery of neuropsychological tests. The primary finding was that ecstasy exposure was significantly related to poorer verbal learning and memory ability in a dose-dependent manner, while no such relationship was observed between ecstasy exposure and executive functioning or attentional ability. Gender was found to significantly moderate the relationship between ecstasy consumption and design fluency. These results suggest primary memory dysfunction among abstinent recreational ecstasy users. This finding is consistent with reports of hippocampal vulnerability, particularly among heavy users.
