Abstract
Background Administration of a single-dose activated charcoal (SDAC) is an effective method used for gastric decontamination and for other types of poisoning and overdose. This is only true when given within the first hour of poison ingestion as the effectivity of SDAC reduces over time. In addition, generally, not all patients are able to avail treatment within the specified period. Hence, multi-dose activated charcoal is regarded as a solution to a delayed process, although, no proof outweighs the use of SDAC. Objective This study aimed to review and assess the adequacy of the past and current use of AC. The author also aimed to offer recommendations believed to be the best method to consider for prehospital care. Methods The author conducted 6,337 online literature searches for this review, wherein seven papers met eligibility criteria for inclusion and analysis. Results In this review, routine administration of AC in poisoning was found not related to the duration of hospital stay nor any other subsequent outcomes following poison ingestion. Further, this review did not establish that administration of AC could improve patient's clinical outcome. Further research and clinical trials is required to determine the efficacy of this therapy to appropriate patients in the prehospital setting. Conclusion Activated charcoal can be used to treat highly acute to life-threatening poisoning if it is administered within the first hour of ingestion. Further studies would be necessary to investigate if this would affect clinical outcome..

Quantitative evaluation of mercury adsorption and removal efficacy of Spirulina (Arthrospira platensis) powder in mice. Arch Microbiol 2022; 204:387. [PMID: 35696005 DOI: 10.1007/s00203-022-03005-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2021] [Revised: 05/14/2022] [Accepted: 05/19/2022] [Indexed: 11/02/2022]
Abstract
Spirulina is a blue-green alga, grown in alkaline water and used for detoxification of several toxic metal ions. Apart from its nutritional value, it is also used for the decontamination of toxic metal ions. Therefore, present study was envisaged to evaluate the adsorption and removal efficiency of Spirulina powder for mercury. The adsorption efficiency of Spirulina was evaluated in terms of weight of adsorbent, contact time, simulated gastric (SGF) and intestinal (SIF) fluid, and mercury concentration. In vivo removal efficacy of Spirulina for mercury was evaluated in mice. The mercury content in major tissues, urine and feces was estimated. The whole tissue retention and excretion of mercury after treatment with Spirulina were taken as a measure of its metal ions removal efficacy. Activated charcoal was taken as a standard adsorbent for comparative study. The maximum adsorption capacity of Spirulina and charcoal for mercury was found to be 66.667 and 158.730 mg g-1 in water, 83.33 and 94.340 mg g-1 in SGF and 125.0 and 133.33 mg g-1 in SIF, respectively. In mice, Spirulina and activated charcoal were significantly reduced the mercury deposition in tissues and facilitated their excretion through feces. Spirulina has shown good adsorption and removal efficacy like activated charcoal. Therefore, Spirulina can be used as a potential adsorbent to remove mercury from the body.

Abstract
INTRODUCTION The use of activated charcoal in poisoning remains both a pillar of modern toxicology and a source of debate. Following the publication of the joint position statements on the use of single-dose and multiple-dose activated charcoal by the American Academy of Clinical Toxicology and the European Association of Poison Centres and Clinical Toxicologists, the routine use of activated charcoal declined. Over subsequent years, many new pharmaceuticals became available in modified or alternative-release formulations and additional data on gastric emptying time in poisoning was published, challenging previous assumptions about absorption kinetics. The American Academy of Clinical Toxicology, the European Association of Poison Centres and Clinical Toxicologists and the Asia Pacific Association of Medical Toxicology founded the Clinical Toxicology Recommendations Collaborative to create a framework for evidence-based recommendations for the management of poisoned patients. The activated charcoal workgroup of the Clinical Toxicology Recommendations Collaborative was tasked with reviewing systematically the evidence pertaining to the use of activated charcoal in poisoning in order to update the previous recommendations. OBJECTIVES The main objective was: Does oral activated charcoal given to adults or children prevent toxicity or improve clinical outcome and survival of poisoned patients compared to those who do not receive charcoal? Secondary objectives were to evaluate pharmacokinetic outcomes, the role of cathartics, and adverse events to charcoal administration. This systematic review summarizes the available evidence on the efficacy of activated charcoal. METHODS A medical librarian created a systematic search strategy for Medline (Ovid), subsequently translated for Embase (via Ovid), CINAHL (via EBSCO), BIOSIS Previews (via Ovid), Web of Science, Scopus, and the Cochrane Library/DARE. All databases were searched from inception to December 31, 2019. There were no language limitations. One author screened all citations identified in the search based on predefined inclusion/exclusion criteria. Excluded citations were confirmed by an additional author and remaining articles were obtained in full text and evaluated by at least two authors for inclusion. All authors cross-referenced full-text articles to identify articles missed in the searches. Data from included articles were extracted by the authors on a standardized spreadsheet and two authors used the GRADE methodology to independently assess the quality and risk of bias of each included study. RESULTS From 22,950 titles originally identified, the final data set consisted of 296 human studies, 118 animal studies, and 145 in vitro studies. Also included were 71 human and two animal studies that reported adverse events. The quality was judged to have a Low or Very Low GRADE in 469 (83%) of the studies. Ninety studies were judged to be of Moderate or High GRADE. The higher GRADE studies reported on the following drugs: paracetamol (acetaminophen), phenobarbital, carbamazepine, cardiac glycosides (digoxin and oleander), ethanol, iron, salicylates, theophylline, tricyclic antidepressants, and valproate. Data on newer pharmaceuticals not reviewed in the previous American Academy of Clinical Toxicology/European Association of Poison Centres and Clinical Toxicologists statements such as quetiapine, olanzapine, citalopram, and Factor Xa inhibitors were included. No studies on the optimal dosing for either single-dose or multiple-dose activated charcoal were found. In the reviewed clinical data, the time of administration of the first dose of charcoal was beyond one hour in 97% (n = 1006 individuals), beyond two hours in 36% (n = 491 individuals), and beyond 12 h in 4% (n = 43 individuals) whereas the timing of the first dose in controlled studies was within one hour of ingestion in 48% (n = 2359 individuals) and beyond two hours in 36% (n = 484) of individuals. CONCLUSIONS This systematic review found heterogenous data. The higher GRADE data was focused on a few select poisonings, while studies that addressed patients with unknown and or mixed ingestions were hampered by low rates of clinically meaningful toxicity or death. Despite these limitations, they reported a benefit of activated charcoal beyond one hour in many clinical scenarios.

Abstract
Emergency management of deliberate self-poisoning (DSP) by drug overdose is common in emergency medicine. There is a paucity of data about the prehospital care of these patients. The principal aim was to describe the intensity of care received by patients with DSP who were managed by prehospital emergency medical service (EMS) physicians. A 48-h cross-sectional study was conducted in 319 EMS and emergency units in France. Patient and poisoning characteristics and treatments administered were recorded. Complications of poisoning, hospitalization, intensive care unit admission and death were recorded until day 30. The primary endpoint was the probability of receiving prehospital intensive care, including fluid resuscitation, vasopressor therapy, invasive ventilation, or antidotal treatments, depending whether prehospital treatment was carried out by an EMS physician or not. Data from 703 patients (median age was 43 [30-52] years, 288 (40%) men) were analyzed. One hundred and fifteen (16%) patients were attended by an EMS physician. Patients attended by EMS physicians were more likely to receive intensive treatment in the prehospital setting [odds ratio (OR) 7.4, 95% confidence interval 4.3-12.9]. These patients had more severe poisoning as suggested mainly by a lower Glasgow Coma Score (13 [8-15] vs. 15 [15-15]; p < 0.001) and a higher rate of admission to an intensive care unit [29 (25%) vs. 15 (2%), p < 0.001]. Patients with DSP attended by prehospital EMS physicians frequently received intensive care. The level of care seemed appropriate for the severity of the poisoning.

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
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.
