However, they can be toxic and cause adverse reactions such as methemoglobinemia. While inhalation is the typical route of usage, the New York City Poison Center has noted an increase in calls related to ingestion. Given the uncertainty of usage instructions at the point of sale, our study aimed to assess instructions provided to consumers about alkyl nitrite use and to evaluate the proximity and co-sale of alkyl nitrites with similarly appearing energy drink shots.</p><p><strong>Methods: </strong>We conducted a cross-sectional convenience sample survey of smoke shops, cannabis dispensaries, and exotic shops within the catchment area of an urban poison center. Plain clothes \"investigators\" (i.e., the researchers) visited these retailers and followed a predetermined protocol and script to request information regarding the availability and usage of alkyl nitrites.

Twenty-one panelists were selected by four clinical toxicology societies (America's Poison Centers®, American Academy of Clinical Toxicology, American College of Medical Toxicology, and Canadian Association for Poison Centres and Clinical Toxicology) to participate as panelists.

However, utilization of veno-venous extracorporeal membrane oxygenation in acutely poisoned patients is largely unknown.</p><p><strong>Method: </strong>We conducted a retrospective study analyzing the epidemiologic, clinical characteristics and survival of acutely poisoned patients placed on veno-venous extracorporeal membrane oxygenation using the Extracorporeal Life Support Organization registry. Adult cases in the United States were included after a systematic search of the registry between January 1, 2003, and November 30, 2019. Study outcomes included survival to discharge, time to cannulation, and changes in metabolic, hemodynamic, and ventilatory parameters stratified by survival.</p><p><strong>Results: </strong>One hundred and seventeen cases were included in the analysis after excluding 216 non-poisoning-related cases. Their median age was 34 years and 69.2% were male. Opioids (45.3%) were most commonly implicated, followed by neurologic drugs (e.g., antidepressants, antiepileptics) (14.5%) and smoke inhalation (13.7%); 23 patients (19.7%) had a pre-extracorporeal membrane oxygenation cardiac arrest. The median time from admission to extracorporeal membrane oxygenation was 47 h with a median duration of extracorporeal membrane oxygenation support of 146.5 h. Survivors were cannulated significantly earlier than non-survivors (25 h versus 123 h; <i>P</i> = 0.02). Eighty-four patients (71.2%) survived to hospital discharge. Clinical parameters (hemodynamic, metabolic, and ventilatory) improved with veno-venous extracorporeal membrane oxygenation support, but no statistically significant difference was noted between survivors and non-survivors.</p><p><strong>Discussion: </strong>Our study showed that veno-venous extracorporeal membrane oxygenation was infrequently utilized for poisoning-associated acute respiratory distress syndrome. Opioids were the most frequently reported exposure among the cases in which indirect lung injury may have occurred from aspiration. Although no specific clinical parameters were associated with survival, early initiation of extracorporeal membrane oxygenation may improve clinical outcomes.</p><p><strong>Conclusions: </strong>The use of veno-venous extracorporeal membrane oxygenation for refractory respiratory failure due to poisoning was associated with a clinically significant survival benefit compared to other respiratory diagnoses requiring veno-venous extracorporeal membrane oxygenation.</p>","PeriodicalId":10430,"journal":{"name":"Clinical Toxicology","volume":" ","pages":"204-211"},"PeriodicalIF":3.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143045711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
