Randomized Controlled TrialSafety of hydroxocobalamin in healthy volunteers in a randomized, placebo-controlled study.
This randomized, double-blind, placebo-controlled, ascending-dose study was conducted in healthy volunteers to evaluate the safety of the investigational cyanide antidote hydroxocobalamin. ⋯ Timely intervention for acute cyanide poisoning could entail administration of an antidote in the prehospital setting based on a presumptive diagnosis. Results of this placebo-controlled study in healthy volunteers corroborate previous studies and French postmarketing experience in cyanide-exposed patients in suggesting that the safety profile of hydroxocobalamin is consistent with prehospital or hospital use.

Practice GuidelineAcetaminophen poisoning: an evidence-based consensus guideline for out-of-hospital management.
The objective of this guideline is to assist poison center personnel in the appropriate out-of-hospital triage and initial management of patients with suspected ingestions of acetaminophen. An evidence-based expert consensus process was used to create this guideline. This guideline applies to ingestion of acetaminophen alone and is based on an assessment of current scientific and clinical information. ⋯ In patients with conditions purported to increase susceptibility to acetaminophen toxicity (alcoholism, isoniazid use, prolonged fasting), the dose of acetaminophen considered as RSTI should be greater than 4 g or 100 mg/kg (whichever is less) per day (Grade D). 3) Gastrointestinal decontamination is not needed (Grade D). Other recommendations: 1) The out-of-hospital management of extended-release acetaminophen or multi-drug combination products containing acetaminophen is the same as an ingestion of acetaminophen alone (Grade D). However, the effects of other drugs might require referral to an emergency department in accordance with the poison center's normal triage criteria. 2) The use of cimetidine as an antidote is not recommended (Grade A).

Further evidence of the usefulness of Acute Physiology and Chronic Health Evaluation II scoring system in acute paraquat poisoning.
We have previously successfully applied the Acute Physiology and Chronic Health Evaluation (APACHE) II system to assess the severity of patients with acute paraquat poisoning, and this article investigates further evidence of the usefulness of APACHE II system in predicting the in-hospital mortality of 64 patients with acute paraquat poisoning over a period of 12 years. The predictive factors including APACHE II score, plasma paraquat concentration, severity index of paraquat poisoning (SIPP), and estimated ingestion dosage of paraquat for evaluating the outcome in paraquat-poisoned patients were assessed. ⋯ The APACHE II score is a simple, reproducible, and practical tool for evaluating the severity of acute paraquat poisoning.
