The results of this review demonstrate that IVFEs are well tolerated when administered in accordance with guideline recommendations.

Synthetic cannabinoids have recently gained popularity as a recreational drug because they are believed to result in a marijuana-like high. This investigation compared synthetic cannabinoids and marijuana exposures reported to a large statewide poison center system. Synthetic cannabinoid and marijuana exposures reported to Texas poison centers during 2010 were identified. The distribution of exposures to the two agents with respect to various demographic and clinical factors were compared by calculating the rate ratio (RR) of the synthetic cannabinoid and marijuana percentages for each subgroup and 95% confidence interval (CI). The proportion of synthetic cannabinoid and marijuana exposures, respectively, were 87.3% and 46.5% via inhalation (RR 1.88, 95% CI 1.38-2.61), 74.9% and 65.7% in male (RR 1.14, 95% CI 0.87-1.51), 40.2% and 56.6% age ≤ 19 years (RR 0.71, 95% CI 0.52-0.98), 79.2% and 58.6% occurring at a residence (RR 1.35, 95% CI 1.02-1.82), 8.4% and 16.2% managed on-site (RR 0.52. 95% CI 0.28-1.00), and 59.3% and 41.4% with serious medical outcomes (RR 1.43, 95% CI 1.03-2.05). Compared to marijuana, synthetic cannabinoid exposures were more likely to be used through inhalation, to involve adults, to be used at a residence, and to result in serious outcomes.

Synthetic cannabinoid abuse is increasing in the United States. Synthetic cannabinoid exposures reported to Texas poison centers in 2010 were identified, and the distribution of exposures by selected factors was determined. There were 464 total cases. The number of exposures increased each month during January-July, then remained relatively constant for the next 5 months. The patients were 73.9% male and 57.3% were 20 years or older. Moderate or major effects or potentially toxic outcome occurred in 59.9% of the exposures. The most frequently reported clinical effects were tachycardia (37.3%), agitation (18.5%), drowsiness (18.5%), vomiting (15.7%), hallucinations (10.8%), and nausea (9.9%).
