Perfil epidemiológico de pacientes intoxicados con acetaminofén con intenciones suicidas / Epidemiological profile of patients intoxicated with acetaminophen for suicidal purposes / Perfil epidemiológico de pacientes intoxicados com acetaminofen (Paracetamol) com intenções suicidas

Objetivo: este estudio busca describir los individuos evaluados por sobredosis de acetaminofén entre 2019 y 2020 en un centro de referencia de trasplante hepático en Colombia. Metodología: estudio derivado del análisis secundario de historias clínicas entre el 1.º de enero de 2019 y el 31 de diciembre de 2020. Los criterios de inclusión abarcan individuos con ingestión aguda y voluntaria de dosis tóxicas de acetaminofén (>4 g/día). Resultados: sesenta y tres casos, 68% mujeres, 67% menores de 18 años y 54% estudiantes. Reportó historia personal de enfermedad psiquiátrica el 60% y el 35% al menos un intento de suicidio previo. La mediana de dosis de acetaminofén fue 15g, 46% refirieron co-ingesta de otras sustancias y 13% estaba bajo efecto de sustancias psicoactivas. El 57% tenía la intención clara de suicidarse, así como 81% vomitó antes de acudir al servicio de urgencias, 22% recibió medidas de descontaminación y 10% no recibió N - acetilcisteína. Quince individuos desarrollaron lesión hepática aguda, nueve con criterios de severidad. Conclusiones: la población era predominantemente joven, la historia de enfermedad psiquiátrica fue muy prevalente y la mayoría refirieron un evento vital que explicara el comportamiento impulsivo de consumo. Ninguno desarrolló criterios para trasplante hepático, lo cual podría explicarse por la edad de los individuos, los episodios de vómito temprano, y la ausencia de enfermedad hepática crónica o de consumo de sustancias hepatotóxicas.

Objective: this study aims to describe patients with overdose intake of acetaminophen between 2019 and 2020 at a reference center for liver transplantation in Colombia. Methodology: study derived from a secondary analysis of the clinical records between January 1st, 2019, to December 31st, 2020. Inclusion criteria were individuals with voluntary acute ingestion of toxic doses of acetaminophen (>4 g/day). Results: sixty-three cases, 68% women, 67% <18-year-old, and 54% students. 60% had personal history of psychiatric illness and 35% reported at least one previous suicide attempt. The median dose of acetaminophen was 15g, 46% referred to co-ingestion with other substances and 13% were under the effect of any psychoactive substance. 57% had a clear intention of suicide. 81% vomited before the arrival to the emergency room, 22% received decontamination intervention with gastric lavage or activated charcoal, and 10% did not receive any dose of N-Acetylcysteine. Fifteen individuals developed an acute liver injury, nine with severity criteria. Conclusions: the population was predominantly young, the personal history of psychiatric disease was highly prevalent, and most of the cases referred a vital event that explains the impulsive behavior in acetaminophen consumption. None developed criteria for liver transplantation, and this could be explained by the young age of the individuals, the episodes of early vomiting, and the absence of chronic liver disease or hepatotoxic substance consumption.

Análise crítica da indicação da lavagem gástrica em intoxicações atendidas em um hospital de ensino / Critical analysis of gastric lavage indication for poisoning cases attended in a university hospital

Objetivo: Avaliar a indicação da lavagem gástrica no tratamento de intoxicações causadas por ingestão. Métodos: Todos os casos de intoxicação causada por ingestão que foram atendidos em dois hospitais do interior de São Paulo e submetidos à lavagem gástrica no período de 1° de janeiro de 2011 a 31 de dezembro de 2015 foram avaliados retrospectivamente quanto à indicação do procedimento, considerando o tempo entre ingestão e atendimento, a toxicidade da substância e as contraindicações para o procedimento. Resultados: Dos 587 casos atendidos, 338 (57,6%) foram submetidos à lavagem gástrica. Dentre esses casos, constatou-se a realização equivocada do procedimento em 95,8% casos. Conclusão: O número de pacientes submetidos à lavagem gástrica neste trabalho foi considerado elevado, mesmo quando orientado pelo centro de atendimento. Apesar da falta de evidências de que a lavagem gástrica traga benefícios nos casos de intoxicação, ela é largamente utilizada em virtude do desconhecimento das indicações e contraindicações desse procedimento por parte dos profissionais de saúde

Objective: To evaluate the indication of gastric lavage in the treatment of poisoning caused by ingestion. Methods: All cases of poisoning caused by ingestion that were treated in two hospitals in inland cities of São Paulo and subjected to gastric lavage from January 1, 2011 to December 31, 2015 were retrospectively assessed as for the indication of the procedure, considering the time between ingestion and care, substance toxicity, and procedure contraindications. Results: Of the 587 cases treated, 338 (57.6%) underwent gastric lavage. The procedure was considered incorrect in 95.8% of cases. Conclusion: The number of patients undergoing gastric lavage in this study was considered high, even when instructed by the center of attendance. Despite the lack of evidence that gastric lavage brings benefits in cases of poisoning, it is widely used due to the lack of knowledge by health professionals of the indications and contraindications of this procedure.

Bezoar gástrico, una aproximación al manejo / Gastric bezoar, an approach to medical management

The presence of bezoars in daily clinical practice is a event that poses a challenge both diagnostic, due to the associated factors in its development, as well as therapeutic. The management of this entity is associated with medical, endoscopic and surgical procedures and it is necessary to know its usefulness in different clinical scenarios. The role of carbonated beverages is increasingly accepted given its low cost, wide availability and high efficiency. For the aforementioned, it seems important to report a series of cases and the management performed.

La presencia de bezoares en la práctica clínica diaria es un evento que establece un desafío diagnóstico, por los factores asociados en su desarrollo, como también terapéutico. El manejo de esta patología se asocia a procedimientos médicos, endoscópicos y quirúrgicos siendo necesario conocer su utilidad en distintos escenarios clínicos. El rol de las bebidas carbonatadas es cada vez más aceptado dado su bajo costo, amplia disponibilidad y alta eficacia. Por lo antes señalado, nos parece importante reportar una serie de casos y el manejo realizado.

A Case of Treatment with QRS Widening in Electrocardiogram after Glyphosate Herbicide Poisoning

Glyphosate herbicides, which are widely used worldwide, are known to have low toxicity. However, excessive intake may cause serious life-threatening complications; therefore, caution is needed when using them. A 51-year-old man visited the hospital after ingesting glyphosate herbicide. At the time of admission, his vital signs were 80/60 mmHg-115/min-20/min-37.3℃. Electrocardiogram (ECG) showed QRS widening and corrected QT (QTc) prolongation, and blood tests showed metabolic acidosis. Treatment with gastric lavage, activated charcoal, sodium bicarbonate and intravenous lipid emulsion therapy was performed. After 2 hours, his blood pressure increased to 130/90 mg, and no QRS widening was observed on ECG.

Toxic Optic Neuropathy Caused by Chlorfenapyr Poisoning

PURPOSE: To report a case of toxic optic neuropathy caused by chlorfenapyr ingestion accompanied by central nervous system involvement. CASE SUMMARY: A 44-year-old female visited our clinic complaining of reduced visual acuity in both eyes for 7 days. She had ingested a mouthful of chlorfenapyr for a suicide attempt 2 weeks prior to the visit. Gastric lavage was performed immediately after ingestion at the other hospital. Her best-corrected visual acuity was finger count 30 cm in the right eye and hand motion in the left eye. Both pupils were dilated by 5.0 mm and the response to light was sluggish in both eyes. A relative afferent pupillary defect was detected in her left eye. Funduscopy revealed optic disc swelling in both eyes. Magnetic resonance imaging of the brain showed a symmetric hyper-intense signal in the white matter tract including the internal capsule, corpus callosum, middle cerebellar peduncle, and brainstem. The patient was diagnosed with toxic optic neuropathy induced by chlorfenapyr ingestion, and underwent high-dose intravenous corticosteroid pulse therapy. Three days later, the best-corrected visual acuity was no light perception in both eyes. Three months later, optic atrophy was observed in both eyes. Optical coherence tomography revealed a reduction in the thicknesses of the retinal nerve fiber layer and ganglion cell and inner plexiform layer in the macular area. CONCLUSIONS: Ingestion of even a small amount of chlorfenapyr can cause severe optic nerve damage through the latent period, despite prompt lavage and high-dose steroid treatment.

Comparison of Clinical Characteristics and Severity of Glyphosate and Glufosinate Herbicide Poisoning Patients

PURPOSE: The number of glyphosate and glufosinate intoxication cases are increasing in Korea. This study was undertaken is to compare the clinical manifestations of poisoning by these two herbicides and to document severities and clinical outcomes. METHODS: We retrospectively evaluated cases of glyphosate or glufosinate intoxication among patients that visited our emergency department between January 1, 2013, and December 31, 2017. Incidences of intoxications were analyzed over this five year period, and underlying diseases, transportation, mental state, shock occurrence, inotropics, gastric lavage, charcoal administration, intubation and ventilator therapy, and hemodialysis were investigated. In addition, we included transfer to the intensive care unit, incidences of pneumonia and of other complications, death, and hopeless discharge. RESULTS: There were 119 cases of glyphosate intoxication and 42 of glufosinate intoxication. Levels of consciousness were lower for glufosinate and vasopressor usage was higher due to a high shock rate (p=0.019). In addition, many patients were referred to the ICU for intubation and ventilation. The incidences of pneumonia and of other complications were significantly higher for glufosinate. CONCLUSION: Overall glufosinate intoxication was found to be more severe than glyphosate intoxication as determined by complication and ICU admission rates.

A Case of Cement Hardening Agent Intoxication with Acute Kidney Injury

Chronic silica nephropathy has been associated with tubulointerstitial disease, immune-mediated multisystem disease, chronic kidney disease, and end-stage renal disease. On the other hand, acute intentional exposure is extremely rare. The authors' experienced a 44-year-old man who took rapid cement hardener (sodium silicate) in a suicide attempt whilst in a drunken state. He visited the emergency department approximately 1 hour after ingestion. Information on the material was obtained after 3 L gastric lavage. The patient complained of a sore throat, epigastric pain, and swollen to blood tinged vomitus. Proton pump inhibitors, hemostats, steroid, and fluids were administered. Nine hours after ingestion, he was administered 200 mL hematochezia. Immediately after, a gastroenterologist performed an endoscopic procedure that revealed diffuse hyperemic mucosa with a color change and variable sized ulceration in the esophagus, whole stomach, and duodenal 2(nd) portion. Approximately 35 hours later, persistent oligouria and progressive worsening of the renal function parameters (BUN/Cr from 12.2/1.2 to 67.5/6.6 mg/dL) occurred requiring hemodialysis. The patient underwent 8 sessions of hemodialysis for 1 month and the BUN/Cr level increased to 143.2/11.2 mg/dL and decreased to 7.6/1.5 mg/dL. He was discharged safely from the hospital. Follow up endoscopy revealed a severe esophageal stricture and he underwent endoscopic bougie dilatation. Acute cement hardener (sodium silicate) intoxication can cause renal failure and strong caustic mucosal injury. Therefore, it is important to consider early hemodialysis and treatment to prevent gastrointestinal injury and remote esophageal stricture.

Survey of Activated Charcoal Administration for Poisoning Patients Visited in Emergency Medical Centers and Emergency Staff's Perception in Korea

PURPOSE: Activated charcoal (AC) has been widely used as a universal antidote. Currently, emergency medical centers in Korea cannot administer AC due to discontinuation of the supply of commercial ready-mixed AC suspension. This study was conducted to investigate the proportion of emergency medical centers that administer AC to poisoning patients and provide basic information for emergency physicians and toxicologists. METHODS: A prospective telephone survey of all of the included emergency medical institutions was conducted. The type of emergency medical institution, average annual number of patients admitted to the emergency department, annual average number of patients who were poisoned and whether the hospital currently utilizes gastric lavage and administration of AC were determined. RESULTS: AC was administered to poisoning patients in 40% of regional emergency medical centers, 59.3% of local emergency medical centers, and 45.9% of local emergency medical rooms. Overall, 37% of total emergency medical institutions did not administer AC due to discontinuation of the commercial ready-mixed AC suspension. Additionally, 77% of emergency physicians in institutions without AC knew AC is necessary for poisoning patients. The rate of vomiting experienced by the medical staff according to types of charcoal showed that the average rate of vomiting was 33% for commercial ready-mixed activated charcoal suspension and 51% for self-prepared charcoal powder (p=0.02). CONCLUSION: AC should be secured promptly in emergency medical institutions. Before the supply of commercial ready-mixed AC suspension becomes again it is essential to develop a standardized regimen for self-preparation of charcoal powder and to educate emergency physicians and toxicologists to its use.

Pneumatosis Cystoides Intestinales and Portomesenteric Venous Gas following Anticholinesterase Pesticide Poisoning

Pneumatosis cystoides intestinalis and portomesenteric venous gas are uncommon radiological findings, but are found commonly in cases of bowel ischemia, or as a result of various non-ischemic conditions. A 72-year-old man visited an emergency center with altered mental status 2 hours after ingestion of an unknown pesticide. On physical examination, he showed the characteristic hydrocarbon or garlic-like odor, miotic pupils with no response to light, rhinorrhea, shallow respiration, bronchorrhea, and sweating over his face, chest and abdomen. Laboratory results revealed decreased serum cholinesterase, as well as elevated amylase and lipase level. We made the clinical diagnosis of organophosphate poisoning in this patient based on the clinical features, duration of symptoms and signs, and level of serum cholinesterase. Activated charcoal, fluid, and antidotes were administered after gastric lavage. A computerized tomography scan of the abdomen with intravenous contrast showed acute pancreatitis, poor enhancement of the small bowel, pneumatosis cystoides intestinalis, portomesenteric venous gas and ascites. Emergent laparotomy could not be performed because of his poor physical condition and refusal of treatment by his family. The possible mechanisms were believed to be direct intestinal mucosal damage by pancreatic enzymes and secondary mucosal disruption due to bowel ischemia caused by shock and the use of inotropics. Physicians should be warned about the possibility of pneumatosis cystoides intestinalis and portomesenteric venous gas as a complication of pancreatitis following anticholinesterase poisoning.

A Successful Management after Cement Ingestion: A Case Report

Cases of the cement ingestion are rare. This paper reports the successful management of cement ingestion with gastric lavage and endoscopic washing. A 69-year-old man who had a stuporous mentality and seizures visited the local emergency room. He was found in his room with cement powder and several liquor bottles. He underwent a gastric lavage in the prior emergency room, which showed evidence of cement ingestion. He was transferred to the emergency center after primary care. Cement mixed with water is a strong alkali and acts as a caustic agent in the gastrointestinal tract. In addition, it can become hard in a few hours and sometimes produce gastric bezoars. Generally, gastric lavage is not recommended for caustic agents. On the other hand, gastric lavage and endoscopic washing was performed repeatedly for successful removal despite the physical and chemical characteristics of cement. Therefore, the active removal of ingested cement by both gastric lavage and endoscopic washing is recommended.

A fatal case of acute bentazone overdose despite cricothyroidotomy during cardiopulmonary resuscitation

Bentazone is classified as a moderately hazardous (class II) herbicide by the World Health Organization. A 53-year-old Korean woman was transferred to the emergency department after a suicide attempt using approximately 500 mL of bentazone one hour prior to admission. Upon admission, she was alert and tachycardia of 125/min was observed. She was treated with gastric lavage and activated charcoal, during which she experienced diarrhea. Two hours after bentazone ingestion, cardiac arrest and muscle rigidity throughout the body occurred. Cardiopulmonary resuscitation was immediately started. Endotracheal intubation after administration of a muscle relaxant (succinylcholine) was unsuccessful because of temporomandibular joint muscle rigidity. Surgical cricothyroidotomy was performed by the emergency physician, but the patient was not resuscitated. For cardiac arrest patients with muscle rigidity caused by bentazone overdose, endotracheal intubation may be challenging because of muscle rigidity, despite appropriate use of muscle relaxants. Early surgical cricothyroidotomy may be the preferred method of airway management in these patients.

Erythromycin infusion prior to endoscopy for acute nonvariceal upper gastrointestinal bleeding: a pilot randomized controlled trial

BACKGROUND/AIMS: The aim of this study was to compare the effects of erythromycin infusion and gastric lavage in order to improve the quality of visualization during emergency upper endoscopy. METHODS: We performed a prospective randomized pilot study. Patients presented with hematemesis or melena within 12 hours and were randomly assigned to the erythromycin group (intravenous infusion of erythromycin), gastric lavage group (nasogastric tube placement with gastric lavage), or erythromycin + gastric lavage group (both erythromycin infusion and gastric lavage). The primary outcome was satisfactory visualization. Secondary outcomes included identification of a bleeding source, the success rate of hemostasis, duration of endoscopy, complications related to erythromycin infusion or gastric lavage, number of transfused blood units, rebleeding rate, and bleeding-related mortality. RESULTS: A total of 43 patients were randomly assigned: 14 patients in the erythromycin group; 15 patients in the gastric lavage group; and 14 patients in the erythromycin + gastric lavage group. Overall satisfactory visualization was achieved in 81% of patients: 92.8% in the erythromycin group; 60.0% in the gastric lavage group; and 92.9% in the erythromycin + gastric lavage group, respectively (p = 0.055). The identification of a bleeding source was possible in all cases. The success rate of hemostasis, duration of endoscopy, and number of transfused blood units did not significantly differ between groups. There were no complications. Rebleeding occurred in three patients (7.0%). Bleeding-related mortality was not reported. CONCLUSIONS: Intravenous erythromycin infusion prior to emergency endoscopy for acute nonvariceal upper gastrointestinal bleeding seems to provide satisfactory endoscopic visualization.

Detection value of free cancer cells in peritoneal washing in gastric cancer: a systematic review and meta-analysis

Intraperitoneal free cancer cells in gastric adenocarcinoma are associated with a poor outcome. However, the true prognostic value of intraperitoneal free cancer cells is still unclear, leading to a lack of consensus in the management of gastric cancer. The aim of the present study is to perform a systematic review and meta-analysis to analyze intraperitoneal free cancer cells-positive patients with regard to tumor oncologic stage, recurrence, grade of cellular differentiation, and survival rates and to analyze the clinical significance of intraperitoneal free cancer cells with regard to prognosis. Databases were searched up to January 2016 for prognostic factors associated with intraperitoneal free cancer cells, including oncologic stage, depth of neoplasm invasion, lymph nodal spread, differentiation grade of the tumor, and recurrence and survival rates. A total of 100 studies were identified. Meta-analysis revealed a clear association between intraperitoneal free cancer cells and a poor prognosis. intraperitoneal free cancer cells -positive patients had higher rates of nodal spread (risk difference: 0.29; p<0.01), serosal invasion (risk difference: 0.43; p<0.01), recurrence (after 60 months of follow-up, risk difference: 0.44; p<0.01), and mortality (after 60 months of follow-up, risk difference: 0.34; p<0.01). Intraperitoneal free cancer cells are associated with a poor outcome in gastric cancer. This surrogate biomarker should be used to guide therapy both prior to and after surgery.

Validez y confiabilidad de una escala de clasificación de limpieza gástrica en endoscopia digestiva alta en población chilena / Validity and reliability of a gastric cleansing scale in upper endoscopyin chilean population

The presence of foam and bubbles during upper gastrointestinal endoscopy (UGE) obscures the view of gastric lesions. Objective: To assess the confidence of a gastric cleansing scale in UGE. Methods: Prospective, multicenter study. The instrument was administered to patients undergoing a UGE examination. For the gastric visualization scale, the stomach was divided in 4 parts and a 1-4 scale was used to classify each part, with a total score of 4 (optimal view of gastric mucosa) and 16 (poor view of gastric mucosa), assessed by 2 independent endoscopists. An initial cleansing score was obtained and later, after cleansing of each studied section, and total. Inter-observer concordance was established by means of Kappa test, and the agreement on the global cleansing score was established with the Bland-Altman plot. Results: 53 patients went under UGE, with an average age of 48,7 years and 62,3 percent female subjects. The main indication for performing the UGE examination was gastroesophageal reflux disease (GERD) (32.1 percent). Average duration of the procedure was 13.6 minutes. The average total gastrointestinal view before cleansing with water was 6.26 points (scale from 4 to 16) and 5.1 points (p < 0.001) after cleansing. 37.7 percent required at least 50 cc of water for cleansing. The difference in the pre and post cleansing score inter-observers was no different of 0. Kappa value obtained in gastric fundus, upper body, lower body and antrum before cleansing was 0.81; 0.71; 0.9 and 0.8, respectively. Kappa value obtained after cleansing of gastric fundus, upper body, lower body and antrum was 0.84; 0.65; 0.81 and 0.78; respectively. The mean difference between inter-observer scores before cleansing was 0.08 (p = 0.51), and after cleansing, 0.02 (p = 0.78)...

La presencia de espuma y burbujas durante la endoscopia digestiva alta (EDA) es una limitante para la visualización de lesiones gástricas. Objetivo: Evaluar la confiabilidad de una escala de clasificación de limpieza gástrica en EDA. Métodos: Estudio prospectivo, multicéntrico. Se aplicó el instrumento a pacientes que estaban agendados para EDA. Para la clasificación de visualización gástrica, el estómago se dividió en 4 porciones y se utilizó una escala de 1 a 4 por porción, sumando un puntaje total entre 4 (óptima visualización de la mucosa) y 16 (pobre visualización de ésta), evaluada por 2 endoscopistas independientes. Se obtuvo un puntaje de limpieza inicial y luego de la limpieza con agua de cada segmento estudiado y total. La concordancia inter-observador se estableció por medio del test de Kappa y el acuerdo para el puntaje global de limpieza fue establecido mediante el gráfico de Bland-Altman. Resultados: 53 pacientes fueron sometidos a EDA, con edad promedio de 48,7 años y 62,3 por ciento de sexo femenino. La principal indicación de EDA fue enfermedad por reflujo gastroesofágico (32,1 por ciento). El tiempo promedio del procedimiento fue 13,6 min. El promedio de visualización gástrica total previo a limpieza con agua fue de 6,26 puntos (escala 4 a 16) y post limpieza 5,1 puntos (p < 0,001). Para la limpieza el 37,7 por ciento requirió al menos 50 cc de agua. La diferencia de puntaje de visualización pre y post limpieza inter observador no fue distinta de 0. En fondo gástrico, cuerpo alto, cuerpo bajo y antro se obtuvo un valor de Kappa previo a limpieza de 0,81; 0,71; 0,9 y 0,8, respectivamente. El valor de Kappa posterior a limpieza en fondo gástrico, cuerpo alto, cuerpo bajo y antro fue 0,84; 0,65; 0,81 y 0,78, respectivamente. La diferencia media de los puntajes inter-observadores previos a la limpieza gástrica fue de 0,08 (p = 0,51) y posterior a la limpieza gástrica fue de 0,02 (p = 0,78)...

Trends of Intentional Poisoning: A Retrospective Single Center Study During 15 Years

PURPOSE: Intentional poisoning is a major public health issue in many parts of the world. This study was conducted to provide details regarding the epidemiology of intentional poisoning in a metropolitan emergency department and to identify the changing patterns and epidemiology of poisoning. METHODS: A retrospective study was conducted to evaluate intentional poisoning of patients who visited the emergency department in a tertiary teaching hospital between 2001 and 2015. All intentional poisoning-related emergency department visits over three five year periods (2001-2005 (P1), 2006-2010 (P2) and 2011-2015 (P3)) were reviewed to investigate trends in intentional poisoning patients. Information regarding patient sex, age, time from episode to admission, psychiatric history, type of intoxicants, alcohol co-ingestion, gastric lavage, charcoal administration, any previous suicide attempts, need for hospitalization and death before discharge was reviewed. RESULTS: A total of 1269 patients were enrolled in this study. The number of patients admitted during each period was P1=515, P2=439 and P3=315. Comparison of the three groups revealed significant differences according to age (p<0.001), psychiatric history (p<0.001), alcohol co-ingestion (p=0.013), gastric lavage (p<0.001), charcoal administration (p<0.001), need for hospitalization (p=0.044), repeated attempt (p<0.001) and type of intoxicants (p<0.001). CONCLUSION: The average age of intentional poisoning patients has increased. While the use of sedatives and multiple drugs increased, the use of pesticides and the antihistamine decreased.

Death Related to the Dehumidifying Agent / 대한법의학회지

Dehumidifying agents are commonly used to remove moisture and odors and are not meant for oral ingestion. The hazards of accidental oral ingestion of dehumidifying agents are not well known. A 31-year-old man with autism drank the liquid desiccant contained in the barrel of a dehumidifier while sleepwalking. The desiccant mainly consisted of calcium chloride. He was taken to the emergency center with persistent vomiting and underwent gastric lavage. The patient was treated for hypercalcemia due to calcium chloride poisoning. He eventually died of multiple organ failure. Autopsy findings were as follows: acute suppurative pneumonia, intra-abdominal inflammation, liver necrosis, acute pancreatitis, and gastrointestinal hemorrhage. Calcium chloride has relatively low toxicity; however, when ingested orally, it can cause severe internal damage, and even death. We suggest active preventive measures to ensure the safe use of dehumidifying agents.

Management of exogenous intoxication by carbamates and organophosphates at an emergency unit / Manejo de intoxicação exógena por carbamatos e organofosforados em uma unidade de emergência

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.

Resumo Objetivo: avaliar e indicar os procedimentos a serem seguidos na unidade de saúde tanto para o diagnóstico como para o tratamento de intoxicações agudas exógenas por carbamatos ou organofosforados. Métodos: estudo descritivo baseado na análise retrospectiva da história clínica de pacientes diagnosticados com intoxicação por carbamatos ou organofosforados admitidos em uma unidade de emergência, entre janeiro e dezembro de 2012. Foram avaliados alguns critérios, como: agente intoxicador; idade do paciente e gênero; causa de envolvimento, circunstâncias e gravidade da intoxicação; sinais e sintomas dos efeitos neurológicos muscarínicos e nicotínicos. Resultados: setenta pacientes (idade média: 25±19,97 anos) formaram a população de estudo. Foi observado que 77,14% deles sofreram intoxicação por carbamatos. Os casos mais graves foram intoxicados por organofosforados, com 68,75% dos pacientes apresentando formas moderadas a graves. Tentativa de suicídio foi a causa principal de envenenamento, com 62 casos (88,57% do total). A administração de atropina foi uma medida terapêutica efetiva para tratamento de sinais e sintomas, como sialorreia (p=0,0006), náusea (p=0,0029) e êmese (p<0,0001). O uso do carvão ativado mostrou efetividade para o combate dos sinais e sintomas apresentados por pacientes em geral (p<0,0001). Conclusão: o uso de atropina e de carvão ativado é uma medida terapêutica altamente efetiva para combater os sinais e sintomas apresentados por pacientes vítimas de intoxicação aguda exógena por carbamatos ou organofosforados.

Clinical study on the treatment of acute paraquat poisoning with sequential whole gastric and bowel irrigation / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To explore the clinical efficacy of early application of sequential gastrointestinal lavage in patients with acute paraquat poisoning by analyzing the clinical data of 97 patients.</p><p><b>METHODS</b>A total of 97 eligible patients with acute paraquat poisoning were divided into conventional treatment group (n = 48) and sequential treatment group (n = 49). The conventional treatment group received routine gastric lavage with water. Then 30 g of montmorillonite powder, 30 g of activated charcoal, and mannitol were given to remove intestinal toxins once a day for five days. The sequential treatment group received 60 g of montmorillonite powder for oral administration, followed by small-volume low-pressure manual gastric lavage with 2.5%bicarbonate liquid. Then 30 g of activated charcoal, 30 g of montmorillonite powder, and polyethylene glycol electrolyte lavage solution were given one after another for gastrointestinal lavage once a day for five days. Both groups received large doses of corticosteroids, blood perfusion, and anti-oxidation treatment. The levels of serum potassium, serum amylase (AMY) alanine aminotransferase (ALT), total bilirubin (TBIL), blood urea nitrogen (BUN), creatinine (Cr), lactate (Lac), and PaO₂of patients were determined at 1, 3, 5, 7, and 10 days. Laxative time, mortality, and survival time of dead cases were evaluated in the two groups.</p><p><b>RESULTS</b>The incidence rates of hypokalemia (<3.5 mmol/L) and AMY (>110 U/L) were significantly lower in the sequential treatment group than in the conventional treatment group (P < 0.05). There were no significant differences in the incidence of ALT (>80 U/L), TBIL (>34.2 µmol/L), BUN (>7.2 mmol/L), and Cr (>177 µmol/L) between the two groups (P>0.05). However, the highest levels of ALT, TBIL, BUN, Cr, and Lac were significantly lower in the sequential treatment group than in the conventional treatment group (P < 0.05). Moreover, the sequential treatment group had significantly lower incidence of PaO₂(<60 mmHg), shorter average laxative time, lower mortality, and longer survival time of dead cases than the conventional treatment group (P < 0.05).</p><p><b>CONCLUSION</b>The early application of sequential gastrointestinal lavage can shorten laxative time, alleviate organ damage in the liver, kidney, lung, and pancreas, reduce mortality, and prolong the survival time of dead cases in patients with acute paraquat poisoning.</p>
