sodium-oxybate and Vomiting

Gamma-hydroxybutyrate (GHB) is a common drug of abuse that can produce serious toxicity, particularly when used with other sedatives. We examined the individual and combined effects of GHB and ethanol in human volunteers.. Sixteen healthy adults (7 men) were given 50 mg/kg GHB (Xyrem), 0.6 g/kg ethanol in 2 doses, alone and combined in a double-blind, placebo-controlled, crossover study. Plasma concentrations, heart rate (HR), blood pressure (BP), and oxygen saturation (O2sat) were serially monitored for 24 hours.. Adverse events included 2 instances of hypotension and 6 episodes of vomiting with GHB-plus-ethanol ingestion. Oxygen saturation was decreased by GHB and ethanol individually, and maximally decreased by the drugs combined (max -2.1% +/- 0.3%, P < 0.0001 vs placebo). Compared with baseline, systolic and diastolic BP were significantly decreased, and HR was increased by ethanol but not affected by GHB alone (maximum systolic BP change -15.7 +/- 3.0 mm Hg, P = 0.0006; maximum HR change 13.5 +/- 2.3 beats per minute, P = 0.006). Ethanol coingestion resulted in 16% higher GHB maximal plasma concentration and 29% longer elimination half-life, indicating possible enhanced bioavailability or reduced clearance of GHB caused by ethanol, however, these effects were not statistically significant.. Modest doses of GHB do not affect hemodynamic function, but O2sat was decreased. Gamma-hydroxybutyrate-plus-ethanol resulted in more adverse effects, including gastrointestinal disturbances, hypotension, and decreased O2sat, but only minimal pharmacokinetic interactions were observed.

In order to identify the sociodemographic, clinical, emergency management and severity differences of drug poisoning treated in Emergency Departments (ED) from a gender perspective, data on patients from 11 Spanish EDs were recorded over 24 months (August 2017-July 2019). The severity of intoxication was compared by sex and was based on the combined adverse event (orotracheal intubation, cardiorespiratory arrest, intensive care hospitalization, and death). We included 4,526 patients (men 75.5%), with a mean age of 33 years. The most frequent drugs were: cocaine (47.8%), cannabis (44.4%) and amphetamines (25.5%). Men consumed more GHB (5.6% vs. 1.9%, p < .001) and less benzodiazepines (8.0% vs. 11.1%, p = .002) and alcohol (57.2% vs. 61.2%, p = .028) than women, with no differences in other types of drugs. Men presented significantly more severe bradycardia (OR = 4.39, 95%CI = 1.03-18.7), chest pain (OR = 1.72, 95%CI = 1.27-2.35) and symptomatic hypertension (OR = 1.56, 95%CI = 1.06-2.30) and less anxiety (OR = 0.74, 95%CI = 0.61-0.89) and vomiting (OR = 0.64, CI95% = 0.51-0.80). Men had more combined adverse events (3.1% vs. 2.0%, p = .047) and a greater intubations (1.9% vs. 1.0%, p = .044), with no significant differences in the adjusted model (OR = 1.349, 95%CI = 0.827-2.202 and OR = 1.371, 95%CI = 0.700-2.685, respectively). Twelve patients died (0.3%), with no differences according to sex. Drug intoxications attended in the ED differ according to sex. GHB, benzodiazepines and alcohol are more frequently involved in men than women. Cardiovascular symptomatology is more prevalent in men, while anxiety and vomiting are more frequent in women, which cannot be explained by differences in sociodemographic characteristics or the drugs used. There were no differences in the severity of the intoxication episodes.. Con el objetivo de identificar, con perspectiva de género, las diferencias sociodemográficas, clínicas, manejo en urgencias y gravedad de las intoxicaciones por drogas atendidas en Servicios de Urgencias Hospitalarias (SUH), se registraron todos los pacientes atendidos en 11 SUH españoles durante 24 meses (agosto 2017-julio 2019). La gravedad de la intoxicación se basó en el evento adverso combinado (intubación orotraqueal, parada cardiorrespiratoria, hospitalización en intensivos, y muerte), comparándose según el sexo. Cuando se encontraron diferencias significativas en sintomatología o gravedad, los resultados se ajustaron por características sociodemográficas y drogas consumidas. Se incluyeron 4.526 pacientes (hombres 75,5%), con edad media de 33 años. Las drogas más frecuentes fueron cocaína (47,8%), cánnabis (44,4%) y anfetaminas (25,5%). Hubo más GHB en hombres (5,6% vs 1,9%, p < ,001) y más benzodiacepinas (8,0% vs 11,1%, p = ,002) y alcohol (57,2% vs 61,2%, p = ,028) en mujeres, sin diferencias en otras de drogas. Los hombres tuvieron significativamente más bradicardia grave (OR = 4,39, IC95% = 1,03-18,7), dolor torácico (OR = 1,72, IC95% = 1,27-2,35) e hipertensión sintomática (OR = 1,56, IC95% = 1,06-2,30) y menos ansiedad (OR = 0,74, IC95% = 0,61-0,89) y vómitos (OR = 0,64, IC95% = 0,51-0,80). Tuvieron también más eventos adversos combinados (3,1% vs 2,0%, p = ,047) y más intubaciones (1,9% vs 1,0%, p = ,044), pero sin diferencias significativas en el modelo ajustado (OR = 1,349, IC95% = 0,827-2,202 y OR = 1,371, IC95% = 0,700-2,685, respectivamente). Fallecieron 12 pacientes (0,3%), sin diferencias según sexo. Concluimos que existen diferencias según el sexo en las drogas que originan intoxicaciones atendidas en los SUH. Las diferencias en sintomatología cardiovascular (más en hombres) y ansiosa o digestiva (más en mujeres) no se explican por diferencias sociodemográficas o de drogas utilizadas. La gravedad de la intoxicación no se ve influida por el sexo.

The U.S. Consumer Product Safety Commission announced a recall of Aqua Dots (Spin Master Ltd.; Toronto, Canada) on November 7, 2007 due to children becoming ill after swallowing beads from these toy craft kits. Reports suggested that the beads contained 1,4-butanediol (1,4-BD), a precursor to gamma-hydroxybutyrate (GHB), rather than the intended, but more expensive 1,5-pentanediol (1,5-PD). We measured the 1,4-BD and 1,5-PD content of Aqua Dots beads to determine if 1,5-PD had been completely substituted with 1,4-BD by the manufacturer, and if the reported clinical effects from swallowing Aqua Dots beads were consistent with the estimated ingested 1,4-BD dose.. In vitro bench research using gas chromatography-mass spectroscopy (GC-MS) was performed. Dilute samples of pure 1,4-BD and 1,5-PD in water were used for the calibration of the GC-MS instrument. We then soaked Aqua Dots beads in water for varying durations, and the resultant solutions were analyzed for 1,4-BD and 1,5-PD content.. Aqua Dots beads weighed 79.3 mg each (+/- 0.6 mg, SD), and contained 13.7% (+/- 2.4%, SD) 1,4-BD by weight; this corresponds to a 1,4-BD content of 10.8 mg (+/- 1.9 mg, SD) per bead. No 1,5-PD was detected in any beads.. Aqua Dots beads contained a surprisingly high amount (nearly 14%) of extractable 1,4-BD. No 1,5-PD was detected, corroborating reports that this chemical had been completely replaced with a substitute that is metabolized into GHB after ingestion. Reports of ataxia, vomiting, seizure activity, and self-limited coma in children are consistent with the ingestion of several dozen Aqua Dots beads.

1,4-Butanediol is an industrial solvent that, when ingested, is converted to gamma-hydroxybutyrate, a drug of abuse with depressant effects, primarily on the central nervous system. After reports of toxic effects of gamma-hydroxybutyrate and its resultant regulation by the federal government, 1,4-butanediol and gamma-butyrolactone, another precursor of gamma-hydroxybutyrate and an industrial solvent, began to be marketed as dietary supplements. We investigated reports of toxic effects due to the ingestion of 1,4-butanediol and reviewed the related health risks.. From June 1999 through December 1999, we identified cases of toxic effects of 1,4-butanediol involving patients who presented to our emergency departments with a clinical syndrome suggesting toxic effects of gamma-hydroxybutyrate and a history of ingesting 1,4-butanediol and patients discovered through public health officials and family members. We used gas chromatography-mass spectrometry to measure 1,4-butanediol or its metabolite, gamma-hydroxybutyrate, in urine, serum, or blood.. We identified nine episodes of toxic effects in eight patients who had ingested 1,4-butanediol recreationally, to enhance bodybuilding, or to treat depression or insomnia. One patient presented twice with toxic effects and had withdrawal symptoms after her second presentation. Clinical findings and adverse events included vomiting, urinary and fecal incontinence, agitation, combativeness, a labile level of consciousness, respiratory depression, and death. No additional intoxicants were identified in six patients, including the two who died. The doses of 1,4-butanediol ingested ranged from 5.4 to 20 g in the patients who died and ranged from 1 to 14 g in the nonfatal cases.. The health risks of 1,4-butanediol are similar to those of its counterparts, gamma-hydroxybutyrate and gamma-butyrolactone. These include acute toxic effects, which may be fatal, and addiction and withdrawal.
