Abstract
Introduction: Amygdalin, marketed misleadingly as supplement "Vitamin B17," is a cyanogenic glycoside. When swallowed, it is hydrolyzed into cyanide in the small intestine, which causes histotoxic hypoxia via inhibition of cytochrome c oxidase. It remains available for purchase online despite a ban from the US Food and Drug Administration. We report a case of massive intentional amygdalin overdose resulting in recurrent cyanide toxicity after initial successful antidotal therapy.Case summary: A 33-year-old woman intentionally ingested 20 g of "apricot POWER B17 Amygdalin" supplements. She presented five hours post-ingestion with vital signs: P 127 bpm, BP 112/65 mmHg, RR 25/min, temperature 98.1 °F, and SpO2 98% RA. She was in agitated delirium, diaphoretic, and mydriatic. Her VBG was notable for a pH of 7.27 (rr 7.32-7.42) and lactate 14.1 mmol/L (rr 0.5-2.2), with ECG demonstrating QTc 538 ms (normal <440 ms). She was empirically treated with hydroxocobalamin and supportive care, but worsened clinically, requiring intubation and additional hydroxocobalamin and sodium thiosulfate, which resolved her toxicity. Twelve hours later, she developed recurrent hypotension, acidemia, and QTc prolongation that resolved with repeat hydroxocobalamin and sodium thiosulfate dosing.Discussion: Our case demonstrates rebound metabolic acidosis after massive amygdalin overdose. Toxicity was associated with prolonged QTc, which warrants further investigation into clinical significance. Redosing of combination antidotal therapy suggested efficacy without adverse effects.

Abstract
OBJECTIVE To describe the characteristics of paediatric patients with suspected poisoning treated by advanced life support (ALS) units, and to evaluate quality indicators (QI) for the prehospital emergency care of these patients. METHOD A one-year observational study of patients under 18 years of age exposed to poisoning and treated by an ALS unit of the Medical Emergency System in Catalonia. Severe clinical criteria were defined, with 8 QI being evaluated for prehospital emergency care of poisoned paediatric patients. RESULTS The study included a total of 254 patients, with a median age of 14 years-old (p25-75 = 7-16), with intentional poisoning in 50.8% of cases. The most frequently involved toxic agent was carbon monoxide (CO) (33.8%). Poisoning was found in 48.8% of those patients, being serious in 16.5%. Intentionally (OR 5.1; 95% CI: 1.9-13.8) and knowledge of the time of exposure (OD 3.1; 95% CI: 1.3-7.3) were independent risk factors associated with the appearance of severe clinical symptoms. Five QI did not reach the quality standard and included, availability of specific clinical guidelines, activated charcoal administration in selected patients, oxygen therapy administration at maximum possible concentration in carbon monoxide poisoning, electrocardiographic assessment in patients exposed to cardiotoxic substances, and recording of the minimum data set. CONCLUSIONS Paediatric patients attended by ALS units showed specific characteristics, highlighting the involvement of CO and adolescents with voluntary poisoning. The QI assessment was useful to detect weak points in the quality of care of these patients and to develop strategies for improvement.

Abstract
Acute poisonings account for a significant proportion of the patient population presenting to intensive care units, whereby mixed drug overdoses and prescription drug overdoses predominate. The aim of this article was to describe indications for screening, diagnosis and therapy monitoring in acute overdoses in the intensive care unit. To conduct this work, a literature search was carried out and a review was written based on guidelines, case reports, expert opinions and scientific publications. Toxidromes are a useful tool for classification of clinical characteristics when the causative agent is initially unknown. Especially in critical care medicine, identifying and quantifying of the causative toxin by enzyme immunoassays, chromatography and mass spectrometry should be attempted. Intensive care treatment of patients with acute overdoses includes not only monitoring and support of vital functions but also methods for primary and secondary elimination of toxins. The indication for the use of extracorporeal procedures should be carefully evaluated and the method should be chosen based on protein binding and molecular size. Lipid emulsion therapy, high-dose insulin euglycaemia therapy and hyperbaric oxygenation are also increasingly used.

Abstract
Introduction Antidotes are agents that negate the effect of a poison or toxin. Antidotes mediate its effect either by preventing the absorption of the toxin, by binding and neutralizing the poison, antagonizing its end-organ effect, or by inhibition of conversion of the toxin to more toxic metabolites. Antidote administration may not only result in the reduction of free or active toxin level, but also in the mitigation of end-organ effects of the toxin by mechanisms that include competitive inhibition, receptor blockade or direct antagonism of the toxin. Mechanism of action of antidotes Reduction in free toxin level can be achieved by specific and non-specific agents that bind to the toxin. The most commonly used non-specific binding agent is activated charcoal. Specific binders include chelating agents, bioscavenger therapy and immunotherapy. In some situations, enhanced elimination can be achieved by urinary alkalization or hemadsorption. Competitive inhibition of enzymes (e.g. ethanol for methanol poisoning), enhancement of enzyme function (e.g. oximes for organophosphorus poisoning) and competitive receptor blockade (e.g. naloxone, flumazenil) are other mechanisms by which antidotes act. Drugs such as N-acetyl cysteine and sodium thiocyanate reduce the formation of toxic metabolites in paracetamol and cyanide poisoning respectively. Drugs such as atropine and magnesium are used to counteract the end-organ effects in organophosphorus poisoning. Vitamins such as vitamin K, folic acid and pyridoxine are used to antagonise the effects of warfarin, methotrexate and INH respectively in the setting of toxicity or overdose. This review provides an overview of the role of antidotes in poisoning. How to cite this article Chacko B, Peter JV. Antidotes in Poisoning. Indian J Crit Care Med 2019;23(Suppl 4):S241-S249.

Abstract
BACKGROUND Oral poisoning is a major cause of mortality and disability worldwide, with estimates of over 100,000 deaths due to unintentional poisoning each year and an overrepresentation of children below five years of age. Any effective intervention that laypeople can apply to limit or delay uptake or to evacuate, dilute or neutralize the poison before professional help arrives may limit toxicity and save lives. OBJECTIVES To assess the effects of pre-hospital interventions (alone or in combination) for treating acute oral poisoning, available to and feasible for laypeople before the arrival of professional help. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, CINAHL, ISI Web of Science, International Pharmaceutical Abstracts, and three clinical trials registries to 11 May 2017, and we also carried out reference checking and citation searching. SELECTION CRITERIA We included randomized controlled trials comparing interventions (alone or in combination) that are feasible in a pre-hospital setting for treating acute oral poisoning patients, including but potentially not limited to activated charcoal (AC), emetics, cathartics, diluents, neutralizing agents and body positioning. DATA COLLECTION AND ANALYSIS Two reviewers independently performed study selection, data collection and assessment. Primary outcomes of this review were incidence of mortality and adverse events, plus incidence and severity of symptoms of poisoning. Secondary outcomes were duration of symptoms of poisoning, drug absorption, and incidence of hospitalization and ICU admission. MAIN RESULTS We included 24 trials involving 7099 participants. Using the Cochrane 'Risk of bias' tool, we assessed no study as being at low risk of bias for all domains. Many studies were poorly reported, so the risk of selection and detection biases were often unclear. Most studies reported important outcomes incompletely, and we judged them to be at high risk of reporting bias.All but one study enrolled oral poisoning patients in an emergency department; the remaining study was conducted in a pre-hospital setting. Fourteen studies included multiple toxic syndromes or did not specify, while the other studies specifically investigated paracetamol (2 studies), carbamazepine (2 studies), tricyclic antidepressant (2 studies), yellow oleander (2 studies), benzodiazepine (1 study), or toxic berry intoxication (1 study). Eighteen trials investigated the effects of activated charcoal (AC), administered as a single dose (SDAC) or in multiple doses (MDAC), alone or in combination with other first aid interventions (a cathartic) and/or hospital treatments. Six studies investigated syrup of ipecac plus other first aid interventions (SDAC + cathartic) versus ipecac alone. The collected evidence was mostly of low to very low certainty, often downgraded for indirectness, risk of bias or imprecision due to low numbers of events.First aid interventions that limit or delay the absorption of the poison in the bodyWe are uncertain about the effect of SDAC compared to no intervention on the incidence of adverse events in general (zero events in both treatment groups; 1 study, 451 participants) or vomiting specifically (Peto odds ratio (OR) 4.17, 95% confidence interval (CI) 0.30 to 57.26, 1 study, 25 participants), ICU admission (Peto OR 7.77, 95% CI 0.15 to 391.93, 1 study, 451 participants) and clinical deterioration (zero events in both treatment groups; 1 study, 451 participants) in participants with mixed types or paracetamol poisoning, as all evidence for these outcomes was of very low certainty. No studies assessed SDAC for mortality, duration of symptoms, drug absorption or hospitalization.Only one study compared SDAC to syrup of ipecac in participants with mixed types of poisoning, providing very low-certainty evidence. Therefore we are uncertain about the effects on Glasgow Coma Scale scores (mean difference (MD) -0.15, 95% CI -0.43 to 0.13, 1 study, 34 participants) or incidence of adverse events (risk ratio (RR) 1.24, 95% CI 0.26 to 5.83, 1 study, 34 participants). No information was available concerning mortality, duration of symptoms, drug absorption, hospitalization or ICU admission.This review also considered the added value of SDAC or MDAC to hospital interventions, which mostly included gastric lavage. No included studies investigated the use of body positioning in oral poisoning patients.First aid interventions that evacuate the poison from the gastrointestinal tractWe found one study comparing ipecac versus no intervention in toxic berry ingestion in a pre-hospital setting. Low-certainty evidence suggests there may be an increase in the incidence of adverse events, but the study did not report incidence of mortality, incidence or duration of symptoms of poisoning, drug absorption, hospitalization or ICU admission (103 participants).In addition, we also considered the added value of syrup of ipecac to SDAC plus a cathartic and the added value of a cathartic to SDAC.No studies used cathartics as an individual intervention.First aid interventions that neutralize or dilute the poison No included studies investigated the neutralization or dilution of the poison in oral poisoning patients.The review also considered combinations of different first aid interventions. AUTHORS' CONCLUSIONS The studies included in this review provided mostly low- or very low-certainty evidence about the use of first aid interventions for acute oral poisoning. A key limitation was the fact that only one included study actually took place in a pre-hospital setting, which undermines our confidence in the applicability of these results to this setting. Thus, the amount of evidence collected was insufficient to draw any conclusions.

Abstract
AIM This study focused on children aged zero to six years with suspected single-dose paracetamol poisoning, which has not been investigated in Denmark. We evaluated the incidence of liver injuries and the use of activated charcoal and N-acetylcysteine treatment. METHODS Our retrospective study was performed in three paediatric hospital centres from 2001 to 2012. Data on symptoms, time of ingestion, blood biochemistry, treatment and adverse reactions were collected. The results were evaluated against the Rumack-Matthew nomogram. RESULTS We identified 221 children (58% male), with a mean age of 2.67 ± 1.05 years. Activated charcoal treatment was given in 87% of cases, but only 15% of the children received treatment within one hour of the suspected paracetamol poisoning. Although 80% of the children received N-acetylcysteine treatment, only one case (0.5%) had a toxic plasma paracetamol level according to the treatment nomogram. Abdominal pain or vomiting was associated with higher paracetamol levels in plasma. None of the children developed liver injuries. CONCLUSION We found a low incidence of significant poisoning and liberal use of N-acetylcysteine and activated charcoal treatment in Danish children aged zero to six years with suspected paracetamol poisoning. Vomiting or abdominal pain was associated with elevated plasma paracetamol levels. No liver injuries were reported.

Abstract
OBJECTIVE To determine the prevalence of rodenticide exposure in cats, describe the use of gastrointestinal decontamination (GID) after rodenticide exposure, and examine the efficacy of GID following exposure to anticoagulant rodenticides (ACR). DESIGN Retrospective study from 2000-2010. SETTING Emergency service of an urban university teaching hospital. ANIMALS One hundred forty-six cats presented for rodenticide exposure. MAIN RESULTS Annually, the number of cats that were presented for rodenticide exposure averaged 13 of 3,336 (0.39%) and totaled 146 cases over 11 years. Cats that had been exposed to rodenticide were significantly more likely to be young (P < 0.001), sexually intact (P < 0.001), and presented in the fall season (P = 0.002). The majority of cats lived indoors (67.6%). The type of rodenticide involved in the exposure was unknown in 50% (71/142) of cases. Of the known types, ACRs were most common (59/142, 41.5%) followed by cholecalciferol (7/142, 4.9%) and bromethalin (5/142, 3.5%). Gastrointestinal decontamination was attempted in 21/36 (58%) cats with exposure to a known ACR. Emesis was attempted in 17/21 (81%) and charcoal administered in 14/21 (67%) cats that underwent GID. This study did not detect an effect of GID efforts on prothrombin time (PT) prolongation 48 hours after exposure to a known ACR. CONCLUSIONS Cats consume rodenticides. Due to the lack of evidence of altered outcome associated with GID in cats exposed to ACRs, a PT should be evaluated 48 hours after first exposure regardless of whether GID is performed. Treatment should be based on the results of the PT. Gastrointestinal decontamination should be performed at the clinician's discretion based on history, risks, calculated toxic dose, low prevalence of ACR toxicosis in cats, general resistance of cats to ACR toxicosis, and treatment options.

Abstract
BACKGROUND Paracetamol (acetaminophen) is the most widely used non-prescription analgesic in the world. Paracetamol is commonly taken in overdose either deliberately or unintentionally. In high-income countries, paracetamol toxicity is a common cause of acute liver injury. There are various interventions to treat paracetamol poisoning, depending on the clinical status of the person. These interventions include inhibiting the absorption of paracetamol from the gastrointestinal tract (decontamination), removal of paracetamol from the vascular system, and antidotes to prevent the formation of, or to detoxify, metabolites. OBJECTIVES To assess the benefits and harms of interventions for paracetamol overdosage irrespective of the cause of the overdose. SEARCH METHODS We searched The Cochrane Hepato-Biliary Group Controlled Trials Register (January 2017), CENTRAL (2016, Issue 11), MEDLINE (1946 to January 2017), Embase (1974 to January 2017), and Science Citation Index Expanded (1900 to January 2017). We also searched the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov database (US National Institute of Health) for any ongoing or completed trials (January 2017). We examined the reference lists of relevant papers identified by the search and other published reviews. SELECTION CRITERIA Randomised clinical trials assessing benefits and harms of interventions in people who have ingested a paracetamol overdose. The interventions could have been gastric lavage, ipecacuanha, or activated charcoal, or various extracorporeal treatments, or antidotes. The interventions could have been compared with placebo, no intervention, or to each other in differing regimens. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data from the included trials. We used fixed-effect and random-effects Peto odds ratios (OR) with 95% confidence intervals (CI) for analysis of the review outcomes. We used the Cochrane 'Risk of bias' tool to assess the risks of bias (i.e. systematic errors leading to overestimation of benefits and underestimation of harms). We used Trial Sequential Analysis to control risks of random errors (i.e. play of chance) and GRADE to assess the quality of the evidence and constructed 'Summary of findings' tables using GRADE software. MAIN RESULTS We identified 11 randomised clinical trials (of which one acetylcysteine trial was abandoned due to low numbers recruited), assessing several different interventions in 700 participants. The variety of interventions studied included decontamination, extracorporeal measures, and antidotes to detoxify paracetamol's toxic metabolite; which included methionine, cysteamine, dimercaprol, or acetylcysteine. There were no randomised clinical trials of agents that inhibit cytochrome P-450 to decrease the activation of the toxic metabolite N-acetyl-p-benzoquinone imine.Of the 11 trials, only two had two common outcomes, and hence, we could only meta-analyse two comparisons. Each of the remaining comparisons included outcome data from one trial only and hence their results are presented as described in the trials. All trial analyses lack power to access efficacy. Furthermore, all the trials were at high risk of bias. Accordingly, the quality of evidence was low or very low for all comparisons. Interventions that prevent absorption, such as gastric lavage, ipecacuanha, or activated charcoal were compared with placebo or no intervention and with each other in one four-armed randomised clinical trial involving 60 participants with an uncertain randomisation procedure and hence very low quality. The trial presented results on lowering plasma paracetamol levels. Activated charcoal seemed to reduce the absorption of paracetamol, but the clinical benefits were unclear. Activated charcoal seemed to have the best risk:benefit ratio among gastric lavage, ipecacuanha, or supportive treatment if given within four hours of ingestion. There seemed to be no difference between gastric lavage and ipecacuanha, but gastric lavage and ipecacuanha seemed more effective than no treatment (very low quality of evidence). Extracorporeal interventions included charcoal haemoperfusion compared with conventional treatment (supportive care including gastric lavage, intravenous fluids, and fresh frozen plasma) in one trial with 16 participants. The mean cumulative amount of paracetamol removed was 1.4 g. One participant from the haemoperfusion group who had ingested 135 g of paracetamol, died. There were no deaths in the conventional treatment group. Accordingly, we found no benefit of charcoal haemoperfusion (very low quality of evidence). Acetylcysteine appeared superior to placebo and had fewer adverse effects when compared with dimercaprol or cysteamine. Acetylcysteine superiority to methionine was unproven. One small trial (low quality evidence) found that acetylcysteine may reduce mortality in people with fulminant hepatic failure (Peto OR 0.29, 95% CI 0.09 to 0.94). The most recent randomised clinical trials studied different acetylcysteine regimens, with the primary outcome being adverse events. It was unclear which acetylcysteine treatment protocol offered the best efficacy, as most trials were underpowered to look at this outcome. One trial showed that a modified 12-hour acetylcysteine regimen with a two-hour acetylcysteine 100 mg/kg bodyweight loading dose was associated with significantly fewer adverse reactions compared with the traditional three-bag 20.25-hour regimen (low quality of evidence). All Trial Sequential Analyses showed lack of sufficient power. Children were not included in the majority of trials. Hence, the evidence pertains only to adults. AUTHORS' CONCLUSIONS These results highlight the paucity of randomised clinical trials comparing different interventions for paracetamol overdose and their routes of administration and the low or very low level quality of the evidence that is available. Evidence from a single trial found activated charcoal seemed the best choice to reduce absorption of paracetamol. Acetylcysteine should be given to people at risk of toxicity including people presenting with liver failure. Further randomised clinical trials with low risk of bias and adequate number of participants are required to determine which regimen results in the fewest adverse effects with the best efficacy. Current management of paracetamol poisoning worldwide involves the administration of intravenous or oral acetylcysteine which is based mainly on observational studies. Results from these observational studies indicate that treatment with acetylcysteine seems to result in a decrease in morbidity and mortality, However, further evidence from randomised clinical trials comparing different treatments are needed.

Abstract
Introduction Poison exposure is a significant problem in emergency departments (EDs) with high admission rates. Our study aims were to describe the demographics, exposure patterns and clinical outcomes of our ED patients as well as to explore predictors of Intensive Care Unit (ICU) / High Dependency (HD) admission. Methods In this retrospective study, we recruited patients aged over 16 years who presented with poison exposure to our ED over one year. We collected demographical and clinical data using our hospital databases. Primary outcomes were mortality rate and disposition status. Secondary outcomes were predictors for ICU/HD admission. Logistic regression was applied to identify these predictors. Results We recruited 615 patients from an ED attendance of 162,159. Four hundred and nineteen (68%) patients were females; the majority [410 (66.7%)] was Chinese. The median age was 33 years [interquartile range (IQR): 24-44]. Four hundred fifty-six (74.1%) and 159 (25.9%) exposures were intentional or accidental respectively. There were no mortalities. The majority [466 (75.8%)] was admitted to the general ward and only 24 (3.9%) cases were ICU/HD admissions. We identified four factors associated with ICU/HD admission. Odds ratios (95% confidence intervals) for hypotension (systolic blood pressure <90 mmHg), pupillary changes, previous psychiatric history and tricyclic antidepressant overdose were 19.7 (5.57-69.65), 31.9 (7.01-145.76), 3.1 (1.08-9.07) and 30.1 (9.40-96.52) respectively. Conclusions Poison exposure is an infrequent ED occurrence with high admission rates but low mortality. Our study identified risk factors for ICU/HD admission that could be used in future studies to triage at-risk patients for treatment escalation.

Abstract
Nonpharmaceutical household products are the most common substances involved in exploratory ingestions in young children. Fortunately, most of these products are not toxic if ingested in small volumes. However, there are several household products that have the potential to cause significant toxicity and, rarely, fatalities in young children. Key products reviewed in this article include alcohols, button batteries, corrosive cleaning products, laundry detergent pods, hydrocarbons, and magnets. [Pediatr Ann. 2017;46(12):e449-e453.].

A primer on nerve agents: what the emergency responder, anesthesiologist, and intensivist needs to know. Can J Anaesth 2017; 64:1059-1070.

Abstract
PURPOSE The purpose of this review article is to familiarize first responders, anesthesiologists, and intensivists with the medical management of patients exposed to nerve agents. SOURCE This review is based on the current medical literature available to the general medical community. PRINCIPAL FINDINGS Nerve agents are some of the deadliest substances known to humanity. Though they kill primarily via muscle paralysis, which leads to respiratory arrest, these agents affect virtually every organ system in the body. Their primary mechanism of action is the body-wide inhibition of cholinesterases. This inhibition leads to the accumulation of acetylcholine, stimulating both nicotinic and muscarinic receptors. After decontamination, the primary treatment is with atropine to control muscarinic symptoms and with oximes to reactivate the cholinesterases and treat the nicotinic symptoms. Atropine doses can be much higher than conventionally used. Seizures are generally best treated with benzodiazepines. Patients with substantial exposure may require ventilatory and intensive care unit support for prolonged periods of time. CONCLUSION While it is unlikely that most medical practitioners will ever encounter nerve agent poisoning, it is critical to be aware of the presenting symptoms and how best to treat patients exposed to these deadly agents. History has shown that rapid medical treatment can easily mean the difference between life and death for a patient in this situation.

Abstract
BACKGROUND AND OBJECTIVES Identifying international differences in the management of acute pediatric poisonings may help improve the quality of care. The objective of this study was to assess the international variation and appropriateness of gastrointestinal decontamination (GID) procedures performed in children and adolescents who present with acute poisonings to emergency departments. METHODS This was an international, multicenter, cross-sectional prospective study including children <18 years with poisoning exposures presenting to 105 emergency departments in 20 countries from 8 global regions belonging to the Pediatric Emergency Research Networks. Data collection started between January and September 2013 and continued for 1 year. The appropriateness of GID procedures performed was analyzed using the American Academy of Clinical Toxicology and the European Association of Poisons Centres and Clinical Toxicologists' recommendations. Multivariate logistic regression was performed to identify independent risk factors for performing GID procedures. RESULTS We included 1688 patients, 338 of whom (20.0%, 95% confidence interval 18.1%-22.0%) underwent the following GID procedures: activated charcoal (166, 49.1%), activated charcoal and gastric lavage (122, 36.1%), gastric lavage (47, 13.9%), and ipecac (3, 0.9%). In 155 (45.8%, 40.5%-51.2%), the GID procedure was considered appropriate, with significant differences between regions. Independent risk factors for GID procedures included age, toxin category, mechanism of poisoning, absence of symptoms, and the region where the intoxication occurred (P < .001). CONCLUSIONS Globally, there are substantial differences in the use and appropriateness of GID procedures in the management of pediatric poisonings. International best practices need to be better implemented.

Abstract
The standardization of the Intensive Care Medicine may improve the management of the adult critically ill patient. However, these strategies have not been widely applied in the Intensive Care Units (ICUs). The aim is to elaborate the recommendations for the standardization of the treatment of critical patients. A panel of experts from the thirteen working groups (WG) of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC) was selected and nominated by virtue of clinical expertise and/or scientific experience to carry out the recommendations. Available scientific literature in the management of adult critically ill patients from 2002 to 2016 was extracted. The clinical evidence was discussed and summarised by the experts in the course of a consensus finding of every WG and finally approved by the WGs after an extensive internal review process that was carried out between December 2015 and December 2016. A total of 65 recommendations were developed, of which 5 corresponded to each of the 13 WGs. These recommendations are based on the opinion of experts and scientific knowledge, and are intended as a guide for the intensivists in the management of critical patients.

Abstract
OBJECTIVE To provide a management approach for adults with calcium channel blocker poisoning. DATA SOURCES, STUDY SELECTION, AND DATA EXTRACTION Following the Appraisal of Guidelines for Research & Evaluation II instrument, initial voting statements were constructed based on summaries outlining the evidence, risks, and benefits. DATA SYNTHESIS We recommend 1) for asymptomatic patients, observation and consideration of decontamination following a potentially toxic calcium channel blocker ingestion (1D); 2) as first-line therapies (prioritized based on desired effect), IV calcium (1D), high-dose insulin therapy (1D-2D), and norepinephrine and/or epinephrine (1D). We also suggest dobutamine or epinephrine in the presence of cardiogenic shock (2D) and atropine in the presence of symptomatic bradycardia or conduction disturbance (2D); 3) in patients refractory to the first-line treatments, we suggest incremental doses of high-dose insulin therapy if myocardial dysfunction is present (2D), IV lipid-emulsion therapy (2D), and using a pacemaker in the presence of unstable bradycardia or high-grade arteriovenous block without significant alteration in cardiac inotropism (2D); 4) in patients with refractory shock or who are periarrest, we recommend incremental doses of high-dose insulin (1D) and IV lipid-emulsion therapy (1D) if not already tried. We suggest venoarterial extracorporeal membrane oxygenation, if available, when refractory shock has a significant cardiogenic component (2D), and using pacemaker in the presence of unstable bradycardia or high-grade arteriovenous block in the absence of myocardial dysfunction (2D) if not already tried; 5) in patients with cardiac arrest, we recommend IV calcium in addition to the standard advanced cardiac life-support (1D), lipid-emulsion therapy (1D), and we suggest venoarterial extracorporeal membrane oxygenation if available (2D). CONCLUSION We offer recommendations for the stepwise management of calcium channel blocker toxicity. For all interventions, the level of evidence was very low.

Abstract
CONTEXT AND OBJECTIVE: The lack of availability of antidotes in emergency services is a worldwide concern. The aim of the present study was to evaluate the availability of antidotes used for treating poisoning in Campinas (SP). DESIGN AND SETTING: This was a cross-sectional study of emergency services in Campinas, conducted in 2010-2012. METHODS: The availability, amount in stock, place of storage and access time for 26 antidotal treatments was investigated. In the hospitals, the availability of at least one complete treatment for a 70 kg adult over the first 24 hours of admission was evaluated based on stock and access recommendations contained in two international guidelines. RESULTS: 14 out of 17 functioning emergency services participated in the study, comprising pre-hospital services such as the public emergency ambulance service (SAMU; n = 1) and public emergency rooms for admissions lasting ≤ 24 hours (UPAs; n = 3), and 10 hospitals with emergency services. Six antidotes (atropine, sodium bicarbonate, diazepam, Phytomenadione, flumazenil and calcium gluconate) were stocked in all the services, followed by 13 units that also stocked activated charcoal, naloxone and diphenhydramine or biperiden. No service stocked all of the recommended antidotes; only the regional Poison Control Center had stocks close to recommended (22/26 antidotal treatments). The 10 hospitals had almost half of the antidotes for starting treatments, but only one quarter of the antidotes was present with stocks sufficient for providing treatment for 24 hours. CONCLUSION: The stock of antidotes for attending poisoning emergencies in the municipality of Campinas is incomplete and needs to be improved.

Abstract
Context Oral activated charcoal (AC) for toxin absorption should be applied as soon as possible. Extra-hospital AC-application on site by medical laypersons with pre-emptive obtained AC may save time, but may be inferior to AC-application by medical professionals. Objective 1) Availability and incidence of pre-emptive stockpiling of AC on site in the German region Bavaria 2) time saved by AC-stockpiling and application on site, 3) quality of AC-application defined by completeness of the applied AC-dose, time needed, incidence of side-effects in lay-care and in professional-care, considering confounding variables: AC-formulation/powder/tablets, recommended AC-dose, patient’s age. Method telephone-interviews in cases with AC-recommendation by a Poison Information Centre (PIC). Lay-care was suggested according to risk-assessment by PIC. Ingestion sites were classified as either apt for AC-stockpiling or not apt. Results 1) availability: In Bavaria only 20%–22% of eligible cases had AC on-hand, 2) time-saving was at least 14 min. 3) Lay-care/professional-care or patient’s age had no significant influence on the completeness of the applied AC-dose, which was higher with AC as powder but negatively correlated with the recommended AC-dose. No significant difference was seen with time needed for application and incidence of side-effects. Conclusion pre-emptive AC-stocking should be encouraged.

Abstract
BACKGROUND We compared the factors that might impact the severity and the prognosis of carbamazepine (CBZ) intoxication in children, as well as the efficacy levels of the treatment options. MATERIAL AND METHODS Demographic information and clinical and laboratory findings for 40 patients were evaluated retrospectively. Predictive parameters for the development of serious complications were studied. RESULTS Median age of patients was 14 years; 65% of the patients were female. The most common pathological clinical finding and laboratory abnormality were inability to awaken the patient and hyperglycemia (45% and 60%, respectively). The incidences of convulsion, coma, and respiratory failure were 14 (35%), 10 (25%), and 3 (7.5%), respectively. The Glasgow Coma Scale (GCS) scores and pH levels at emergency service admission were significantly lower in the severe intoxication group and the ICU admission group, and body temperature and serum glucose and lactate levels were significantly higher in these groups. A significantly negative correlation was found between the serum CBZ level and the GCS score, but the serum CBZ level was found to be significantly positively correlated with the lactate level. CONCLUSIONS According to our study, the GCS score at admission to hospital, the serum CBZ, glucose, pH, and lactate levels, and body temperature might be useful in predicting serious CBZ intoxication and prognosis in pediatric cases. We conclude that invasive treatment methods, such as hemodialysis or albumin-enhanced continuous venovenous hemodialysis, should be used in patients who do not respond to supportive treatment.

Abstract
OBJECTIVE The use of single dose activated charcoal (SDAC) as a means of gastric decontamination is declining. The present study examined the potential use of SDAC in common overdose scenarios by Australian emergency doctors, compared with clinical toxicologists and current guidelines. METHODS We conducted a cross-sectional survey of emergency doctors and toxicologists on the use of SDAC. The survey covered demographic data, education and previous use of SDAC and six clinical scenarios. The scenarios selected included agents not bound to SDAC, sustained-release preparations and ingestions at varying time points. Statistical calculations were performed using Fisher's exact test. RESULTS There were 397 emergency doctors and 20 toxicologists who responded to the survey. Seventy-one per cent (n = 280/397) of emergency doctors indicated they had received some education on decontamination. Eighty-three per cent (n = 331/397) had administered SDAC during their medical career, 29% (n = 117/397) within the past year. There was a significant difference in responses between emergency doctors and toxicologists in two scenarios; a toxic paracetamol ingestion presenting within 1 h (P = 0.009) and verapamil ingestion in a 3 year old boy (P = 0.001). Toxicologists were more likely to administer SDAC in these scenarios, 89% (n = 16/18) and 88% (n = 15/17), respectively, compared with 52% (n = 197/381) and 43% (n = 158/371) of emergency doctors. CONCLUSIONS Our study showed that there is a significant variation in the use of SDAC between toxicologists and emergency doctors in some scenarios. Clinical toxicologists are more likely to administer SDAC in certain overdose settings. It is essential to provide education on the benefits versus actual risks of SDAC in acute poisoning so that doctors will understand when to administer SDAC or seek further advice.

Abstract
In the case of a nuclear accident or a terrorist attack by a "dirty bomb," there is a risk of external and internal contamination with radionuclides in addition to external irradiation. Internal irradiation as a consequence of radionuclide incorporation is associated with a higher risk of stochastic radiation effects (e.g., tumors). Decorporation treatment will enhance the elimination of radionuclides and reduce the committed effective dose as a metric of stochastic health effects. Although treatment efficacy is better when started early, beginning the therapy without knowing the committed effective dose may unnecessarily expose the patient to the side effects of the medication. The question is: Delay the therapy to wait for the results of internal dosimetry or start the therapy promptly on spec? To prove insight into this question, a selective review of the literature was conducted. The importance of the initiation time of treatment in the efficacy of decorporation treatment can be explained with pharmacokinetic laws and first order processes determining the disposition of xenobiotics in the organism. Nevertheless, there is no internationally accepted standard on when to start a decorporation therapy (exception: iodide). The "precautionary approach," emphasizing the importance of the committed effective dose for the indication of treatment, is competing with the "urgent approach" advocating the administration of medication "a priori" within several hours. A review of the literature actually indicates that the most important drugs used for decorporation are well tolerated with few adverse effects. In consideration of the higher efficacy and the low side-effects of a short-term treatment, initiating decorporation therapy as soon as possible after internal contamination, even before the committed effective dose has been assessed, appears to be a reasonable approach. The decision of continuation or discontinuation of the therapy should be taken after internal dosimetry is completed on the basis of the committed effective dose.

Abstract
Between 1993 and 2004, patients with antidepressant poisoning admitted to an emergency department (ED) were analysed retrospectively with regard to demographics, clinical findings and treatment attempts. Age, gender, suicide attempts, classification of antidepressants, Glasgow Coma Scale (GCS) score, ECG findings, need for endotracheal intubation, follow-up period and Antidepressant Overdose Risk Assessment (ADORA) criteria were analysed by SPSS software. A total of 356 antidepressant poisoning cases were evaluated. Tricyclic antidepressants (TCA), especially opipramol and amitriptyline, were the most common agents (58.4%). The most frequent ECG finding was sinus tachycardia (40.7%, n=145). Endotracheal intubation was required in 9.6% of cases. Patients with TCA ingestion had a longer observation time in the ED, abnormal ECG findings, abnormal physical examination findings and more ADORA criteria, than patients who ingested selective serotonin re-uptake inhibitors (SSRI) (P=0.008, P=0.008, P<0.001, P<0.001). It was found that the patients who ingested TCA (P=0.001), poisoned with amitriptyline (P=0.001), patients with GCS scores of 8 and less (P=0.001), patients with two or more ADORA criteria (P=0.001), with seizures (P=0.001), with abnormal ECG (P=0.012), and patients with a history of two or more suicide attempts were intubated more frequently. Suicide attempts, classification of the antidepressant, ECG findings, seizure, GCS score and number of detected ADORA criteria affect the need for intubation in patients with antidepressant poisoning.

Abstract
AIM To describe various types of Chinese hospitals' emergency department (ED) physicians' knowledge of antidotes and the comparative availability of toxicological treatments at these hospitals. METHODS We emailed a written survey to the ED doctors of 900 hospitals in China. The hospitals' names and addresses were obtained and randomly selected from the 6214 hospitals registered by the Chinese Medical Association. The survey included 23 questions on antidotes to commonly seen poisonings as well as questions on the availability of antidotes and decontamination techniques at each hospital. RESULTS Six hundred and fifty three hospital emergency directors responded to the survey 72.6% response rate). Overall knowledge of antidotes is not high and varied depending on antidote. Physicians in Eastern China, those working in tertiary-level hospitals and those working in hospitals with higher numbers of beds performed significantly better. On average, only 35.6% of the 23 antidotes were available in all reporting hospitals; 54.1% can get these antidotes from nearby hospitals and 42.0% can get them from a local CDC poison control center. However, only 57.3% can get a requested antidote within two hours. Gastric lavage is the most widely used decontamination procedure, and the availability of extracorporeal decontamination techniques is between 67.2% and 79.6% (depending on type). CONCLUSION Knowledge of specific antidotes correlated significantly with size, type, and region of hospital in China rather than with individual physician characteristics. Significant antidotes remain unavailable or unavailable within 2 h in about half of all hospitals surveyed, although all major acute decontamination treatments and techniques seem quite prevalent.

Abstract
PURPOSE The current epidemic of prescription opioid abuse and misuse in the United States is discussed, with an emphasis on the pharmacist's role in ensuring safe and effective opioid use. SUMMARY U.S. sales of prescription opioids increased fourfold from 1999 to 2010, with an alarming rise in deaths and emergency department visits associated with the use of fentanyl, hydrocodone, oxycodone, and other opioid medications. Signs and symptoms of opioid toxicity may include altered mental status, hypoventilation, decreased bowel motility, central nervous system and respiratory depression, peripheral vasodilation, pulmonary edema, hypotension, bradycardia, and seizures. In patients receiving long-term opioid therapy for chronic pain, urine drug testing is an important tool for monitoring and assessment of therapy; knowledge of opioid metabolic pathways and assay limitations is essential for appropriate use and interpretation of screening and confirmatory tests. In recent years, there has been an increase in federal enforcement actions against pharmacies and prescription drug wholesalers involved in improper opioid distribution, as well as increased reliance on state-level prescription drug monitoring programs to track patterns of opioid use and improper sales. Pharmacies are urged to implement or promote appropriate guidelines on opioid therapy, including the use of pain management agreement plans; policies to ensure adequate oversight of opioid prescribing, dispensing, and waste disposal; and educational initiatives targeting patients as well as hospital and pharmacy staff. CONCLUSION Pharmacists in hospitals and health systems can play a key role in recognizing the various forms of opioid toxicity and in preventing inappropriate prescribing and diversion of opioids.

Abstract
The Extracorporeal Treatments in Poisoning (EXTRIP) Workgroup conducted a systematic literature review using a standardized process to develop evidence-based recommendations on the use of extracorporeal treatment (ECTR) in patients with phenytoin poisoning. The authors reviewed all articles, extracted data, summarized findings, and proposed structured voting statements following a predetermined format. A 2-round modified Delphi method was used to reach a consensus on voting statements, and the RAND/UCLA Appropriateness Method was used to quantify disagreement. 51 articles met the inclusion criteria. Only case reports, case series, and pharmacokinetic studies were identified, yielding a very low quality of evidence. Clinical data from 31 patients and toxicokinetic grading from 46 patients were abstracted. The workgroup concluded that phenytoin is moderately dialyzable (level of evidence = C) despite its high protein binding and made the following recommendations. ECTR would be reasonable in select cases of severe phenytoin poisoning (neutral recommendation, 3D). ECTR is suggested if prolonged coma is present or expected (graded 2D) and it would be reasonable if prolonged incapacitating ataxia is present or expected (graded 3D). If ECTR is used, it should be discontinued when clinical improvement is apparent (graded 1D). The preferred ECTR modality in phenytoin poisoning is intermittent hemodialysis (graded 1D), but hemoperfusion is an acceptable alternative if hemodialysis is not available (graded 1D). In summary, phenytoin appears to be amenable to extracorporeal removal. However, because of the low incidence of irreversible tissue injury or death related to phenytoin poisoning and the relatively limited effect of ECTR on phenytoin removal, the workgroup proposed the use of ECTR only in very select patients with severe phenytoin poisoning.

Abstract
Sometimes mistakenly characterized as a 'universal antidote,' activated charcoal (AC) is the most frequently employed method of gastrointestinal decontamination in the developed world. Typically administered as a single dose (SDAC), its tremendous surface area permits the binding of many drugs and toxins in the gastrointestinal lumen, reducing their systemic absorption. Like other decontamination procedures, the utility of SDAC attenuates with time, and, although generally safe, it is not free of risk. A large body of evidence demonstrates that SDAC can reduce the absorption of drugs and xenobiotics but most such studies involve volunteers and have little generalizability to clinical practice. Few rigorous clinical trials of SDAC have been conducted, and none validate or refute its utility in those patients who are intuitively most likely to benefit. Over the past decade, a growing body of observational data have demonstrated that SDAC can elicit substantial reductions in drug absorption in acutely poisoned patients. The challenge for clinicians rests in differentiating those patients most likely to benefit from SDAC from those in whom meaningful improvement is doubtful. This is often a difficult determination not well suited to an algorithmic approach. The present narrative review summarizes the data supporting the benefits and harms of SDAC, and offers pragmatic suggestions for clinical practice.

Abstract
Summary Objectives: to evaluate and indicate the procedure to be followed in the health unit, both for diagnosis and the treatment of acute exogenous intoxications by carbamates or organophosphates. Methods: a descriptive study based on retrospective analysis of the clinical history of patients diagnosed with intoxication by carbamates or organophosphates admitted at the emergency unit of the Hospital de Urgências de Sergipe Governador João Alves (HUSE) between January and December of 2012. Some criteria were evaluated, such as: intoxicating agent; patient's age and gender; place of event, cause, circumstances and severity of the intoxication; as well as signs and symptoms of the muscarinic, nicotinic and neurological effects. Results: seventy patients (average age: 25±19.97) formed the study's population. It was observed that 77.14% of them suffered carbamate intoxication. However, organophosphate intoxications were more severe, with 68.75% of patients presenting moderate to severe forms. Suicide attempt was the leading cause of poisoning, with 62 cases (88.57% of total). Atropine administration was an effective therapeutic approach for treating signs and symptoms, which included sialorrhea (p=0.0006), nausea (p=0. 0029) and emesis (p lt0.0001). The use of activated charcoal was shown effective, both in combating the signs and symptoms presented by both patient groups (p <0.0001). Conclusion: it is concluded that the use of atropine and activated charcoal is highly effective to treat the signs and symptoms developed by patients presenting acute exogenous intoxication by carbamates or organophosphates.

Abstract
AIMS To investigate the pharmacokinetics (PK) of sertraline in overdose and the effect of single dose activated charcoal (SDAC). METHODS Patients presenting to a toxicology unit with sertraline overdoses had demographic and clinical information recorded, and serial serum collected for measurement of sertraline concentrations. Monolix® version 4.2 was used to develop a population PK model of sertraline overdose and the effect of SDAC. Uncertainty in dose time was accounted for by shifting dose time using lag time with between subject variability (BSV). BSV on relative fraction absorbed was used to model uncertainty in dose. RESULTS There were 77 timed sertraline concentrations measured in 28 patients with sertraline overdoses with a median dose of 1550 mg (250-5000 mg). SDAC was given to seven patients between 1.5 and 4 h post-overdose. A one compartment model with lag time of 1 h and first order input and elimination adequately described the data. Including BSV on both lag time and relative fraction absorbed improved the model. The population PK parameter estimates for absorption rate constant, volume of distribution and clearance were 0.895 h(-1) , 5340 l and 130 l h(-1) , respectively. The calculated half-life of sertraline following overdose was 28 h (IQR 19.4-30.6h). When given up to 4 h post-overdose, SDAC significantly increased the clearance of sertraline by a factor of 1.9, decreased the area under the curve and decreased the maximum plasma concentration (Cmax ). CONCLUSIONS Sertraline had linear kinetics in overdose with parameter values similar to those in therapeutic use. SDAC is effective in increasing clearance when given 1.5 to 4 h post-overdose.

Abstract
The increasing prevalence of obesity in developed nations has far-reaching implications for medical toxicology. The management of obese patients is complicated by comorbid illnesses, changes in cardiovascular and respiratory physiology, alterations in pharmacokinetics, and a lack of studies to identify appropriate dosing for current therapeutics and antidotes. In this review article, we examine obesity-associated physiologic and pharmacokinetic changes that may increase the vulnerability of obese patients to overdose. Further research is needed to characterize the relationship between drug toxicity and obesity.

Abstract
ABSTRACTWe describe the course of a toddler who ingested a massive amount of levothyroxine and review treatment options for such overdoses. A 2½-year-old boy presented shortly after an ingestion of up to 7.6 mg of levothyroxine (potentially as much as 700 µg/kg). He was initially asymptomatic, treated with oral charcoal 1 g/kg, and discharged home from the emergency department after a few hours. He returned approximately 24 hours later with a temperature of 38.5°C, heart rate of 163 beats per minute, respiratory rate of 30 breaths per minute, and blood pressure of 136/70 mm Hg. He had a slightly decreased appetite and no signs or symptoms of infection. He was admitted to hospital and treated with oral acetaminophen. The initial free thyroxine (T4) was > 100 pmol/L and free triiodothyronine (T3) was 35.3 pmol/L. The patient had desquamation of the palms and soles, hair loss, and irritability during the month following the ingestion. Resolution of the elevated free T4occurred by 12 days post-ingestion and normalization of the thyroid-stimulating hormone by 7 weeks post-ingestion. There were no longterm sequelae. Levothyroxine overdose can result in significant complications, including seizures and arrhythmias, both of which should be monitored for. However, as our case illustrates, massive ingestion of levothyroxine in children typically follows a benign course.

Abstract
OBJECTIVE To compare the effectiveness of single dose activated charcoal, single dose activated charcoal with sorbitol, and multidose activated charcoal in reducing plasma carprofen concentrations following experimental overdose in dogs. DESIGN Randomized, four period cross-over study. SETTING University research setting. ANIMALS Eight healthy Beagles. INTERVENTIONS A 120 mg/kg of carprofen was administered orally to each dog followed by either (i) a single 2 g/kg activated charcoal administration 1 hour following carprofen ingestion (AC); (ii) 2 g/kg activated charcoal with 3.84 g/kg sorbitol 1 hour following carprofen ingestion (ACS); (iii) 2 g/kg activated charcoal 1 hour after carprofen ingestion and repeated every 6 hours for a total of 4 doses (MD); (iv) no treatment (control). MEASUREMENTS AND MAIN RESULTS Plasma carprofen concentrations were obtained over a 36-hour period following carprofen ingestion for each protocol. Pharmacokinetic modeling was performed and time versus concentration, area under the curve, maximum plasma concentration, time to maximum concentration, and elimination half-life were calculated and compared among the groups using ANOVA followed by Tukey's multiple comparisons test. Activated charcoal, activated charcoal with sorbitol (ACS), and multiple-dose activated charcoal (MD) significantly reduced the area under the curve compared to the control group. AC and MD significantly reduced the maximum concentration when compared to the control group. MD significantly reduced elimination half-life when compared to ACS and the control group. There were no other significant differences among the treatment groups. CONCLUSIONS Activated charcoal and ACS are as effective as MD in reducing serum carprofen concentrations following experimental overdose in dogs. Prospective studies are warranted to evaluate the effectiveness of AC, ACS, and MD in the clinical setting.

Abstract
OBJECTIVE The effects of activated charcoal (AC) mixed with cathartics for gastric decontamination in the management of organophosphate (OP) poisoning remain unknown due to limited clinical evidence. This exploratory study assessed the effectiveness of premixed AC-sorbitol as a treatment for OP poisoning. MATERIALS AND METHODS This retrospective observational case study included patients who either did not receive AC-sorbitol or received a single dose of AC-sorbitol within 24 h after OP ingestion. The patients were divided into three groups: no AC-sorbitol treatment, patients who received AC-sorbitol within 1 h of OP ingestion, and patients who received AC-sorbitol more than 1 h after OP ingestion. Mortality, the development of respiratory failure, and the duration of mechanical ventilation were used as outcome measurements for effectiveness, whereas aspiration pneumonia and electrolyte imbalance were employed as safety measurements. RESULT Among 262 patients with OP poisoning, 198 were included. Of these, 133 patients did not receive AC-sorbitol, whereas 14 and 51 patients received AC-sorbitol within 1 h or more than 1 h after ingestion, respectively. The time from ingestion to hospital arrival and time from ingestion to administration of atropine and pralidoxime differed among the groups, whereas other characteristics, including age, amount ingested, and type of ingested OP, were similar among the groups. Univariate and multivariate analysis demonstrated that the administration of AC-sorbitol was not associated with outcome measures for effectiveness and did not significantly increase either aspiration pneumonia or electrolyte imbalances during hospitalization. DISCUSSION AND CONCLUSION The administration of AC-sorbitol exerted neither beneficial nor harmful effects on the outcomes of OP-poisoned patients regardless of the time from OP ingestion to administration, compared with those of patients who did not receive AC-sorbitol. However, this study enrolled a small number of patients who received AC-sorbitol; further qualified trials with a sufficient number of patients are therefore needed.

Abstract
CONTEXT The extent of non-absorbed drug burden in the GI tract following overdose is unknown. Patients who present with clinical signs of toxicity may not undergo decontamination due to assumption that the drug has already been completely absorbed and because of limited scientific evidence of benefit for routine GI decontamination in poisoned patients. OBJECTIVE The goal of this study was to assess whether people who die of an oral overdose have unabsorbed drug present in the GI tract. The secondary goal was to analyze pharmacologic characteristics of retained drugs when present. MATERIALS AND METHODS Retrospective review of autopsy reports from 2008 to 2010, whose cause of death was determined as "intoxication" or "overdose, was performed at the Office of Chief Medical Examiner of the City of New York (OCME NYC)." Decedents of all ages were identified via electronic OCME database. Inclusion criteria were as follows: 1) cause of death "intoxication" or "overdose" noted by forensic autopsy, 2) ingestion of a solid drug formulation. RESULTS 92 out of 1038 autopsies (9%) that met inclusion criteria had documentation of retained pill fragments, granules, paste, sludge, slurry, or whole pills in the GI tract. The most common drugs found were opioids and anticholinergics. Ninety-eight percent (98%) of the retained drugs were either modified-release preparations or drugs known to slow GI transit. Most decedents were dead on arrival; there were twelve in-hospital deaths and eleven patients died in the Emergency Department. Bupropion and venlafaxine were responsible for four deaths in those who received medical care. One person died in the ICU following bupropion ingestion. DISCUSSION AND CONCLUSION Overdose of an oral drug that either has modified-release properties or slows GI tract motility may result in substantial unabsorbed drug burden remaining in the GI tract.

Abstract
OBJECTIVE We studied the complications and timing implications of prehospital activated charcoal (PAC). Appropriateness of PAC administration was also evaluated. METHODS We retrospectively reviewed prehospital records over 32 months for overdose cases, where PAC was administered. Cases were assessed for amount and type of ingestant, clinical findings, timing of PAC, timing of transport and arrival into the emergency department (ED), and complications. Encounter duration in cases of PAC was compared with that, for all cases during the study period, where an overdose patient who did not receive activated charcoal was transported. RESULTS Two thousand eight hundred forty-five total cases were identified. In 441 cases, PAC was given; and complications could be assessed. Two hundred eighty-one of these had complete information regarding timing of ingestion, activated charcoal administration, and transport. The average time between overdose and PAC was 49.8 minutes (range, 7-199 minutes; median, 41.0 minutes; SD, 30.4 minutes). Complications included emesis (7%), declining mental status (4%), declining blood pressure (0.4%), and declining oxygen saturation (0.4%). Four hundred seventeen cases of PAC had documentation of timing of emergency medical service (EMS) arrival on scene and arrival at the ED. Average EMS encounter time was 29 minutes (range, 10-53 minutes; median, 27.9 minutes). Two thousand forty-four poisoning patients were transported who did not receive PAC. The average EMS encounter time for this group was 28.1 minutes (range, 4-82 minutes; median, 27.3 minutes), not significantly different (P =.114). CONCLUSIONS Prehospital activated charcoal did not appear to markedly delay transport or arrival of overdose patients into the ED and was generally safe.

Abstract
Context. The Extracorporeal Treatments in Poisoning (EXTRIP) workgroup was created to provide evidence and consensus-based recommendations on the use of extracorporeal treatments (ECTRs) in poisoning. Objectives. To perform a systematic review and provide clinical recommendations for ECTR in carbamazepine poisoning. Methods. After a systematic literature search, the subgroup extracted the data and summarized the findings following a pre-determined format. The entire workgroup voted via a two-round modified Delphi method to reach a consensus on voting statements, using a RAND/UCLA Appropriateness Method to quantify disagreement. Anonymous votes were compiled, returned, and discussed in person. A second vote determined the final recommendations. Results. Seventy-four articles met inclusion criteria. Articles included case reports, case series, descriptive cohorts, pharmacokinetic studies, and in-vitro studies; two poor-quality observational studies were identified, yielding a very low quality of evidence for all recommendations. Data on 173 patients, including 6 fatalities, were reviewed. The workgroup concluded that carbamazepine is moderately dialyzable and made the following recommendations: ECTR is suggested in severe carbamazepine poisoning (2D). ECTR is recommended if multiple seizures occur and are refractory to treatment (1D), or if life-threatening dysrhythmias occur (1D). ECTR is suggested if prolonged coma or respiratory depression requiring mechanical ventilation are present (2D) or if significant toxicity persists, particularly when carbamazepine concentrations rise or remain elevated, despite using multiple-dose activated charcoal (MDAC) and supportive measures (2D). ECTR should be continued until clinical improvement is apparent (1D) or the serum carbamazepine concentration is below 10 mg/L (42 the μ in μmol/L looks weird.) (2D). Intermittent hemodialysis is the preferred ECTR (1D), but both intermittent hemoperfusion (1D) or continuous renal replacement therapies (3D) are alternatives if hemodialysis is not available. MDAC therapy should be continued during ECTR (1D). Conclusion. Despite the low quality of the available clinical evidence and the high protein binding capacity of carbamazepine, the workgroup suggested extracorporeal removal in cases of severe carbamazepine poisoning.
