Estudo de fase II de pregabalina para prevenção de náuseas e vômitos induzidos por quimioterapia / Phase II study of pregabalin for the prevention of chemotherapy induced nausea and vomiting

Para avaliar o papel da pregabalina na proteção das náuseas e vômitos induzidos pela quimioterapia, foi realizado um ensaio clínico de fase II, aleatorizado, duplamente cego, controlado por placebo, para investigar se a pregabalina poderia melhorar o controle completo das náuseas e vômitos (desfecho primário). Inscrevemos 82 pacientes virgens de quimioterapia, programados para receber quimioterapia moderadamente e altamente emetogênica. Todos os doentes receberam ondansetron 8mg por via intravenosa, dexametasona 10mg antes da quimioterapia no primeiro dia e, dexametasona 4 mg por via oral, b.d., nos dias dois e três. Os doentes foram distribuídos aleatoriamente para tomar pregabalina 75 mg ou placebo, bd, desde a noite anterior à quimioterapia até ao quinto dia. A resposta completa global não foi estatisticamente significativa entre os grupos (53,7 versus 48,8%, respetivamente, no grupo da pregabalina e no grupo de controlo (P=0,65)). Também não houve diferença estatística significativa durante a fase aguda (primeiras 24 horas) e a fase tardia (24-120h): 80,5% versus 82,9% (P=0,77), 53,7 versus 51,2% (P=0,82), respectivamente. Neste estudo não foi identificada ação da pregabalina na prevenção de náuseas e vômitos induzidos por quimioterapia. Número de registo no Clinicaltrial.gov: NCT04181346.

To evaluate the role of pregabalin in the protection of chemotherapy-induced nausea and vomiting, we performed a phase II randomized, double-blind, placebo-controlled trial to investigate whether pregabalin could improve the complete control of nausea and vomiting (primary end point). We enrolled 82 chemotherapy-naive patients, scheduled to receive moderately and highly emetogenic chemotherapy. All patients received IV ondansetron 8mg, dexamethasone 10mg before chemotherapy on day one and oral dexamethasone 4mg, b.d., on days two and three. Patients were randomly assigned to take pregabalin 75mg or placebo, bd, from the night before chemotherapy to day five. The overall complete response was not statistically significant between the groups (53.7 versus 48.8%, respectively, in the pregabalin group and the control group (P=0.65)). There was also no significant difference during the acute phase (first 24 hours) and delayed phase (24-120h): 80.5% versus 82.9% (P=0.77), 53.7 versus 51.2% (P=0.82), respectively. There is no role for pregabalin preventing chemotherapy-induced nausea and vomiting. Clinicaltrial.gov registration number: NCT04181346.

Objetivo las náuseas y los vómitos inducidos por la quimioterapia siguen siendo un reto importante para los pacientes que recibieron un trasplante de células madre hematopoyéticas. Este estudio tiene como objetivo sintetizar la evidencia disponible sobre los regímenes de profilaxis antiemética en los pacientes con neoplasias hematológicas que recibieron un trasplante de células madre hematopoyéticas, con el fin de identificar el mejor estándar de cuidado. Métodos se llevará a cabo una revisión sistemática utilizando las bases de datos MEDLINE a través de PubMed, EMBASE, Clinical-Trials.gov y Cochrane. Se considerarán los estudios escritos en inglés, francés, italiano o español. Después de seleccionar los estudios de acuerdo con los criterios de inclusión y exclusión, 2 revisores independientes extraerán los datos y evaluarán el riesgo de sesgo en los artículos seleccionados. Este protocolo se ha elaborado de acuerdo con las recomendaciones de las guías PRISMA-P (Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols). Este protocolo está registrado en PROSPERO (Prospective Register of Ongoing Systematic Reviews) CRD42023406380. Discusión las náuseas y los vómitos inducidos por la quimioterapia son un efecto secundario incapacitante que supone un reto importante para los pacientes con neoplasias hematológicas. A pesar de la publicación de diversas guías sobre profilaxis antiemética, ninguna de ellas incluye recomendaciones específicas para cada régimen de quimioterapia. Por lo tanto, analizar los regímenes de profilaxis antiemética primaria en los pacientes con neoplasias hematológicas que recibieron un trasplante de progenitores hematopoyéticos sería valioso para mejorar la calidad de vida de estos pacientes.

Post-operative nausea and vomiting prophylaxis: A meta-review on systematic reviews and meta-analyses

Introduction: Postoperative nausea and vomiting (PONV) are common complications in surgical patients undergoing general anesthesia, and multiple strategies have been suggested to prevent them. Objective: To describe the available evidence on the effectiveness of pharmacological and non-pharmacological strategies for preventing PONV in adults undergoing surgery under general anesthesia, as reported in previous meta-analyses and systematic reviews. Methodology: An overview of systematic reviews and meta-analyses was conducted. Searches were performed in PubMed, EBSCO, EMBASE, Cochrane Database, Science Direct, and Scopus, without restrictions as to gender, clinical condition, or date of publication, including articles in Spanish, French, and English only. Two reviewers independently and in duplicate did the screening, data extraction, quality evaluation, and risk of bias assessment according to AMSTAR-2. The PRISMA and PRIOR statements were followed for reporting. PROSPERO registration number CRD42021251999. Results: Out of 80 candidate articles, three were viable for meta-analysis. 1.5 mg to 18 mg doses of Dexamethasone showed a significant reduction in the risk of PONV, with a RR of 0.48 (95 % CI 0.41-0.57; p<0.001), I2=63 % (p=0.07), and a NNTc of 5 and 7. Other effective strategies included the use of acoustic stimulation/acupuncture/acupressure, 5HT3 antagonists, NK1 antagonists, gabapentinoids, haloperidol, droperidol, metoclopramide, midazolam, mirtazapine, among others. The risk of publication bias was low. Conclusion: Different strategies are effective for PONV prophylaxis in surgeries under general anesthesia. Dexamethasone shows the best available evidence at the moment. The documented methodological quality suggests the need for better studies to establish the effectiveness of the strategies.

High versus low frequency transcutaneous acupoint electrical stimulation as an adjunct therapy to prevent nausea and vomiting in the first 24 hours after infusion of high-grade emetic chemotherapy: a randomized controlled trial / Estimulação elétrica transcutânea de alta versus baixa frequência como terapia adjuvante para prevenir náuseas e vômitos nas primeiras 24 horas após a infusão de quimioterapia emética de alto grau: um estudo controlado randomizado

Introdução: A estimulação elétrica transcutânea em pontos de acupuntura (TAES) foi testada como terapia antiemética. Objetivo: Avaliar a eficácia de duas frequências diferentes de corrente elétrica como terapia adjuvante para a prevenção de náusea e vômito. Métodos: Este ensaio clínico controlado por placebo comparou a incidência de náusea e vômito (nas primeiras 24 horas após a infusão de quimioterapia emética de alto grau) em 61 mulheres (54 ± 11 anos) com câncer de mama em três modos de TAES: alta frequência (HF:150 Hz), baixa frequência (LF:10 Hz) e placebo (P). Os eletrodos foram fixados no ponto de acupuntura PC6 e uma corrente bipolar simétrica (largura de pulso 200 µs) foi aplicada em uma única sessão de 30 minutos antes do início da infusão de quimioterapia. Todos os pacientes recebem infusões fixas de tratamento antiemético (ondansetrona - 8mg) e orientação de uso de medicação de resgate, se necessário, conforme rotina para infusões de ciclofosfamida associada à antraciclina. Resultados: A incidência de náusea foi de 47% no P, 45% na HF e 26% na LF. Embora não significativa, a intervenção com LF-TAES no ponto de acupuntura PC6, alcançou valores relevantes na redução do risco relativo de desenvolver náuseas (RR = 0,51; IC 95% = 0,18 a 1,44; p = 0,18) e tendência de melhora na sensação de bem estar (p = 0,06) e pontuação mais baixa na Edmonton Symptom Rating Scale (p = 0,08). A incidência de vômitos e o consumo de doses antieméticas de resgate foram muito semelhantes entre os grupos. Conclusão: Novos estudos com LF e HF de TAES como terapia adjuvante na prevenção de náuseas e vômitos devem ser realizados para confirmar essa hipótese.

Uso de ondansetrón en el manejo de los vómitos asociados a gastroenteritis aguda en Pediatría de Atención Primaria. Posicionamiento del Grupo de Trabajo de Gastroenterología y Nutrición de la AEPap / Use of ondansetron in the management of vomiting associated with acute gastroenteritis in primary care pediatrics. Positioning of the Gastroenterology and Nutrition Working Group of the Spanish Association of Primary Care Pediatrics (AEPap)

Los vómitos incoercibles, asociados o no a gastroenteritis aguda (GEA), son la principal causa de deshidratación en niños, siendo un motivo de consulta frecuente en Atención Primaria (AP). Los posibles efectos secundarios de los antieméticos han dado lugar a una reducción drástica en su uso en las últimas décadas. Desde hace varios años existe experiencia en el uso de ondansetrón con buenos resultados para el tratamiento de los vómitos de repetición asociados a GEA, fundamentalmente en las unidades de urgencia hospitalaria. Su uso en Atención Primaria es mucho más limitado y no se dispone del fármaco en los botiquines de los centros de salud de la mayoría de las comunidades autónomas. El objetivo de esta revisión es analizar la efectividad para esta indicación y los efectos secundarios de ondansetrón y valorar la pertinencia de su uso en Atención Primaria (AU)

Incoercible vomiting associated with acute gastroenteritis (AGE) is the main cause of dehydration in children, being a frequent reason for consultation in primary care. The side effects of antemetics have led to a drastic reduction in their use in recent decades. For several years there has been experience in the use of ondansetron with good results for the treatment of repeated vomiting associated with AGE, mainly in hospital emergency units. Its use in primary care is much more limited and the drug is not available as emergency medication in the majority of the Spanish Primary Care Centers. The objective of this review is to analyze the effectiveness and side effects of ondansetron and assess the relevance of its use in primary care. (AU)

Medical treatment for acute renal colic. / Tratamiento médico del cólico renoureteral en su fase aguda.

INTRODUCTION: Renoureteral colic (CRU) is the most common urological emergency, with a wide spectrum of severity that generates high morbidity and high health costs. However, there is no homogeneous scheme of pharmacological treatment in its acutephase. AIMS: The main objective of our work is to evaluate the effectiveness and safety profile of the different drugs used in the treatment of CCR and to propose a practical treatment scheme. The secondary objectives are to evaluate the role of fluid therapy in CRU and the treatment of CRU in pregnant women. MATERIAL AND METHODS: We have carried out a literature search on PubMed using the MeSH terms "renalcolic", "treatment", "anti-inflammatory drugs", "antiemeticdrugs", "fluid therapy" and "pregnant". The most relevant clinical trials, meta-analyses and systematic reviews published from 1 January 2005 to 15 September 2020 in Spanish, English and French were reviewed. RESULTS: In the different studies reviewed, non-steroidalanti-inflammatory drugs (NSAIDs) show better pain control, with lower rescue doses and fewer side effects than treatment with opioids. However, fluid therapy has failed to demonstrate an impact on the treatment of CRU. CONCLUSIONS: The initial treatment for CRU is NSAIDs, reserving opioids for successive treatment lines. The control of vegetative cortex can be accomplished with Ondansetron as first choice.

INTRODUCCIÓN: El cólico renoureteral (CRU) es la urgencia urológica más frecuente, con un amplio espectro de gravedad que genera una alta morbilidad y elevados costes sanitarios. Sin embargo, no existe un esquema homogéneo de tratamiento farmacológico en su fase aguda. OBJETIVOS: El objetivo principal de nuestro trabajo es evaluar la efectividad y perfil de seguridad de los distintos fármacos empleados en el tratamiento del CRU y proponer un esquema práctico de tratamiento. Los objetivos secundarios son evaluar el papel de la fluidoterapia en el CRU y el tratamiento del CRU en embarazadas.MATERIAL Y MÉTODOS: Hemos realizado una búsqueda bibliográfica en PubMed utilizando los términos MeSH "renal colic", "treatment", "anti-inflammatory- drugs", "antiemetic drugs", "fluid therapy" y "pregnant". Se revisaron ensayos clínicos, metaanálisis y revisiones sistemáticas de mayor relevancia, publicados desde el 1 de enero de 2005 hasta el 15 de septiembre de 2020, escritos en lengua española, inglesa y francesa. RESULTADOS: En los diferentes estudios revisados los antiinflamatorios no esteroideos (AINES) muestran un mejor control del dolor, con menores dosis de rescate y menos efectos secundarios que el tratamiento con opioides. Sin embargo, la fluidoterapia no ha logrado demostrar una repercusión en el tratamiento del CRU. CONCLUSIONES: El tratamiento de primera elección para el CRU son los AINES, reservando los opioides para sucesivas líneas de tratamiento. El control del cortejo vegetativo se puede realizar con ondansetrón comoprimera elección.

[Effect of palonosetron, ondansetron and dexamethasone in the prevention of postoperative nausea and vomiting in video cholecystectomy with total venous anesthesia with propofol-remifentanil - randomized clinical trial]. / Efeito da palonosetrona, ondansetrona e dexametasona na prevenção de náusea e vômito pós­operatório em videocolecistectomia com anestesia venosa total com propofol­remifentanil ­ ensaio clínico randomizado duplo cego.

INTRODUCTION AND OBJECTIVES: The incidence of Postoperative Nausea and Vomiting (PONV) after video cholecystectomy is high. Progress in pharmacological PONV prophylaxis includes a new generation of 5-HT3 antagonists. This study aims to assess the effect of the 5-HT3 antagonist in postanesthetic antiemetic management of patients submitted to laparoscopic cholecystectomy with total intravenous anesthesia. METHODS: Sixty individuals who underwent video cholecystectomy were randomized into three groups of 20 individuals according to the treatment administered: 0.125 mg of palonosetron (Group 1); 4 mg of ondansetron associated with 4 mg of dexamethasone (Group 2); 4 mg of dexamethasone (Group 3). General intravenous anesthesia was performed with propofol, remifentanil and rocuronium. The group to which the participant belonged was concealed from the investigator who assessed drug effect. PONV was assessed using the Rhodes Scale at 12 and 24 hours after surgery. Rescue medication was 0.655 to 1.5 mg of droperidol. RESULTS: Group 1 presented a lower incidence of PONV and required less rescue medication in the first postoperative hour. There was no significant difference among the three groups regarding PONV incidence in the first 12 postoperative hours. Groups 1 and 2 were superior to Group 3 regarding the control of PONV from 12 to 24 hours, and after rescue medication from 12 to 24 hours. Group 1 showed significantly superior nausea control in the first 12 postoperative hours. CONCLUSIONS: The present study showed evidence that palonosetron is superior to the drugs compared regarding a protracted antiemetic effect and less requirement of rescue drugs, mainly related to its ability to completely inhibit the uncomfortable symptom of nausea.

Resumo Justificativa e objetivo: Náuseas e Vômitos no Pós-Operatório (NVPO) têm alta incidência após videocolecistectomia. Avanços na profilaxia farmacológica de NVPO incluem a nova geração de antagonista 5-HT3. O objetivo deste estudo foi avaliar o efeito do antagonista 5-HT3 no controle antiemético pós-anestésico em videocolecistectomia com anestesia venosa total. Método: Estudo realizado no HC-UFU (Hospital Terciário). Sessenta indivíduos submetidos a videocolecistectomia foram randomizados em três grupos de igual número, sendo administrados 0,125 mg de palonosetrona (Grupo 1); 4 mg de ondasetrona e 4 mg de dexametasona (Grupo 2); ou 4 mg de dexametasona (Grupo 3). A anestesia geral venosa foi realizada com propofol, remifentanil e rocurônio. O avaliador do efeito da droga desconhecia o grupo ao qual o indivíduo pertencia. NVPO foi avaliada aplicando a Escala de Rhodes após 12 e 24 horas do término da cirurgia. Para resgate terapêutico, foi estabelecido 0,655−1,5 mg de droperidol. Resultado: Observou-se no Grupo 1 menor incidência de NVPO e de resgate terapêutico na primeira hora de PO. Não foi observada diferença significativa entre os três grupos com relação a ocorrência de NVPO nas primeiras 12 horas de pós-operatório. Os grupos 1 e 2 foram superiores ao Grupo 3 no que se refere ao controle de NVPO de 12 a 24 horas e após o resgate de 12−24 horas. Observou-se que o controle de náuseas nas primeiras 12 horas de pós-operatório do Grupo 1 foi significantemente superior. Conclusão: O presente estudo mostrou evidências da superioridade da palonosetrona às demais drogas empregadas no que se refere ao efeito antiemético prolongado e menor necessidade de resgate, principalmente na capacidade de inibir completamente o desconfortável sintoma de náusea.

Risk factors associated with antineoplastic chemotherapy-induced nausea and vomiting / Fatores de risco associados a náuseas e vômitos induzidos por quimioterapia antineoplásica

ABSTRACT OBJECTIVE: To estimate the incidence and to evaluate risk factors for antineoplastic nausea and vomiting with high and moderate emetogenic chemotherapy in adult patients in the first treatment cycle. METHODS: Prospective cohort study with follow-up of 269 adults during the first cycle of antineoplastic chemotherapy. The incidence of nausea and vomiting was evaluated in the acute phase (0-24 hours), in the late phase (24 hours-5th day) and in the total phase (0-5th day). RESULTS: In total, 152 patients underwent high emetogenic chemotherapy and 117 moderate emetogenic chemotherapy. The relative frequency of nausea was higher when compared with vomiting in the acute phase (p < 0.001) and in the late phase (p < 0.001). The risk factors identified were: age group ≤ 49 years (odds ratio = 0.47; 95%CI 0.23-0.95) and 50-64 years (odds ratio = 0.45; 95%CI 0.23-0.87), tobacco use (odds ratio = 0.35; 95%CI 0.14-0.88), and high emetogenic chemotherapy (odds ratio 0.55; 95%CI 0.31-0.95). CONCLUSION: The incidence of nausea was higher than that of vomiting, and adverse effects were more frequent in the late phase. The results suggest the risk factors for chemotherapy-induced nausea and vomiting are tobacco, age (young adults), and high emetogenic chemotherapy.

RESUMO OBJETIVO: Estimar a incidência e avaliar os fatores de risco para náuseas e vômitos induzidos por antineoplásicos com alto e moderado potencial emético em pacientes adultos, no primeiro ciclo de tratamento. MÉTODOS: Estudo de coorte prospectiva, com 269 adultos acompanhados durante o primeiro ciclo de quimioterapia antineoplásica. A incidência de náuseas e vômitos foi avaliada na fase aguda (0-24 horas), na fase tardia (24 horas-5° dia) e na fase total (0-5° dia). RESULTADOS: 152 pacientes foram submetidos a quimioterápico com alto potencial emético e 117 a moderado potencial emético. A frequência relativa de náuseas foi maior quando comparada à de vômitos na fase aguda (p < 0,001) e na fase tardia (p < 0,001). Os fatores de risco identificados foram: faixa etária ≤ 49 anos (odds ratio = 0,47; IC95% 0,23-0,95) e 50-64 anos (odds ratio = 0,45; IC95% 0,23-0,87), uso de tabaco (odds ratio = 0,35; IC95% 0,14-0,88) e alto potencial emético dos quimioterápicos (odds ratio 0,55; IC95% 0,31-0,95). CONCLUSÃO: A incidência de náuseas foi maior do que a de vômitos, e na fase tardia os efeitos adversos foram mais frequentes. Os resultados sugerem que os fatores de risco para náuseas e vômitos induzidos por quimioterapia são o tabaco, a idade (adultos jovens) e o alto potencial emético do quimioterápico.

Extrapiramidalismo por antieméticos / Extrapyramidal Side Effects of Antiemetics / Reações extrapiramidais causadas por antieméticos

Resumen: Los antieméticos son usados frecuentemente por diversas áreas de la medicina, aunque existe una tendencia a subestimar sus efectos adversos neurológicos. El objetivo del presente estudio de revisión fue revisar la literatura sobre la fisiología, farmacología, factores predisponentes, clínica y manejo del extrapiramidalismo por antieméticos. Se realizó una búsqueda en la literatura de artículos de revistas científicas, libros y trabajos de grado. Se utilizaron los buscadores Medline, LILACS, PubMed, EMBASE, Current contents y Google Scholar con las siguientes palabras claves: deshidratación, gastroenteritis, vómitos, antieméticos, distonía, dopamina, hipertermia, citocromo, meto-clopramida y domperidona. Se obtuvieron 252 artículos, de los cuales 50 fueron considerados aptos para la revisión. A partir del análisis, se concluyó que el uso de antieméticos es de uso frecuente por medicina general y especialidades como anestesiología y pediatría, por lo cual un conocimiento sobre los efectos extrapiramidales permitirá un diagnóstico y manejo temprano.

Abstract: Antiemetics are frequently used by various areas of medicine, although there is a tendency to underestimate their neurological adverse effects. This paper aims to review the literature on the physiology, pharmacology, predisposing factors, clinical picture, and management of the extrapyramidal side effects of antiemetics. Scientific journal articles, books, and dissertations were searched. The search engines Medline, LILACS, PubMed, EMBASE, Current Contents, and Google Scholar were used with the following keywords: dehydration, gastroenteritis, vomit, antiemetics, dystonia, dopamine, hyperthermia, cytochrome, metoclopramide, and domperidone. Two hundred and fifty-two articles were obtained, 50 of which were considered suitable for review. From the analysis, it was concluded that antiemetics are often used by general medicine and specialties such as anesthesiology and pediatrics; therefore, knowledge of the extrapyramidal effects will allow early diagnosis and treatment.

Resumo: Os antieméticos são frequentemente usados por diversas áreas da medicina, embora possamos constatar uma tendência a subestimar seus efeitos adversos neurológicos. O objetivo do presente estudo é revisar a literatura sobre a fisiologia, a farmacologia, os fatores predisponentes, a clínica e o tratamento de reações extrapiramidais causadas por antieméticos. Foi realizada uma busca na literatura por artigos de revistas científicas, livros e monografias. Os mecanismos de busca Medline, LILACS, PubMed, EMBASE, Current contents e Google Scholar foram utilizados com as seguintes palavras-chave: desidratação, gastroenterite, vómito, antieméticos, distonia, dopamina, hipertermia, citocromo, metoclopramida e domperidona. Foram encontrados 252 artigos, dos quais 50 foram considerados aptos para a revisão. A partir da análise, concluiu-se que os antieméticos são frequentemente utilizados pela medicina geral e especialidades, como anestesiologia e pediatria, portanto, o conhecimento dos efeitos extrapiramidais possibilitará um diagnóstico e tratamento precoces.

Terapia combinada en la profilaxis de las náuseas y vómitos postoperatorios en cirugía laparoscópica / Combined therapy and prophylaxis in postoperative nausea and vomiting in laparoscopic surgery

Introducción: Las náuseas y vómitos postoperatorios representan un problema frecuente tanto para el paciente como para el médico anestesiólogo. Se estima que la incidencia está en un 25 a 30 por ciento de los pacientes postoperados. Objetivo: Profundizar en los conocimientos relacionados con la terapia combinada en la profilaxis de las náuseas y vómitos postoperatorios. Métodos: Se realizó una revisión de los artículos publicados en las bases de datos Pubmed, Scielo, Medline y Cochrane, relacionados con el tema. Desarrollo: La naturaleza multifactorial de las náuseas y vómitos postoperatorios requiere de un enfoque multimodal para su tratamiento, el cual debe ser profiláctico más que terapéutico, con el objetivo de minimizar el riesgo. No es factible modificar sustancialmente las variables dependientes del paciente y de la intervención quirúrgica, pero se puede influir directamente sobre las anestésicas. En varios estudios se han identificado los diferentes factores de riesgo para náuseas y vómitos postoperatorios y a partir de estos se han desarrollado modelos predictivos que permiten evaluar la probabilidad del evento. Conclusiones: Las náuseas y vómitos postoperatorios constituyen un fenómeno frecuente en el postoperatorio. Para su profilaxis es recomendable el uso de terapias combinadas (antidopaminérgicos, antihistamínicos, anticolinérgicos, antagonistas de la serotonina, esteroides y antagonistas de la neurokinina-1) dado su componente multifactorial. Esta forma de afrontar dicho problema permite disminuir la frecuencia de estos síntomas, las complicaciones postoperatorias y facilitar la recuperación más inmediata del paciente(AU)

ABSTRACT Introduction: Postoperative nausea and vomiting represent a frequent problem for both the patient and the anesthesiologist. It is estimated that the incidence of these are present in 25-30 percent of postoperative patients. Objective: To go deepen in the knowledge related to physiopathology and combination therapy in the prophylaxis of postoperative nausea and vomiting. Method: A bibliographic review was made of the articles published in the Pubmed, Scielo, Medline and Cochrane data bases, related to the topic, belonging to authors dedicated to the study of this problem. Development: The multifactorial nature of postoperative nausea and vomiting requires a multimodal approach to its treatment, which should be prophylactic rather than therapeutic, with the objective of minimizing risk. It is not reasonable to modify the dependent variables of the patient and of the surgical intervention, but it is possible to directly influence the anesthetics. In several studies, the different risk factors for PONV have been identified and, from these, predictive models have been developed to evaluate the probability of the event. Conclusions: postoperative nausea and vomiting are a frequent phenomenon in the postoperative period. For its prophylaxis the use of combination therapies (antidopaminergic, antihistaminic, anticholinergic, serotoninantagonists, steroids and neurokinin-1 antagonists) is recommended, givenits multifactorial component. This way of dealing with this problema allows us to reduce the frequency of these symptoms, postoperative complications and facilitate the patient's most immediate recovery(AU)

Bromopride, metoclopramide, or ondansetron for the treatment of vomiting in the pediatric emergency department: a randomized controlled trial / Bromoprida, metoclopramida ou ondansetrona no tratamento de vômito no departamento de emergência pediátrica: ensaio controlado randomizado

Abstract Objective: To compare the effectiveness of a single intramuscular dose of bromopride, metoclopramide, or ondansetron for treating vomiting. Methods: Randomized controlled trial including children 1-12 years of age presenting with acute vomiting at the pediatric emergency department. Outcomes: Number of children that stopped vomiting at one, six, and 24 h following treatment; episodes of diarrhea; acceptance of oral liquids; intravenous rehydration; return to hospital and side effects. Results: There were 175 children who completed the study. Within the first hour after treatment, all drugs were equally effective, with ondansetron preventing vomiting in 100%, bromopride in 96.6%, and metoclopramide in 94.8% of children (p = 0.288). Within six hours, ondansetron was successful in preventing vomiting in 98.3% of children, compared to bromopride and metoclopramide, which were successful in 91.5% and 84.4% of patients, respectively (p = 0.023). Within 24 h, ondansetron was superior to both other agents, as it remained efficacious in reducing vomiting in 96.6% of children, as opposed to 67.8% and 67.2% with bromopride and metoclopramide, respectively (p = 0.001). The ondansetron group showed better acceptance of oral liquids (p = 0.05) when compared to the bromopride and metoclopramide. The ondansetron group did not show any side effects in 75.9% of cases, compared to 54.2% and 53.5% in the bromopride and metoclopramide groups, respectively. Somnolence was the most common side effect. Conclusions: A single dose of ondansetron is superior to bromopride and metoclopramide in preventing vomiting six hours and 24 h following treatment. Oral fluid intake after receiving medication was statistically better with Ondansetronwhile also having less side effects compared to the other two agents.

Cyclophosphamide administration routine in autoimmune rheumatic diseases: a review / Rotina de administração de ciclofosfamida em doenças autoimunes reumáticas: uma revisão

Abstract Cyclophosphamide is an alkylating agent widely used for the treatment of malignant neoplasia and which can be used in the treatment of multiple rheumatic diseases. Medication administration errors may lead to its reduced efficacy or increased drug toxicity. Many errors occur in the administration of injectable drugs. The present study aimed at structuring a routine for cyclophosphamide use, as well as creating a document with pharmacotherapeutic guidelines for the patient. The routine is schematized in three phases: pre-chemotherapy, administration of cyclophosphamide, and post-chemotherapy, taking into account the drugs to be administered before and after cyclophosphamide in order to prevent adverse effects, including nausea and hemorrhagic cystitis. Adverse reactions can alter laboratory tests; thus, this routine included clinical management for changes in white blood cells, platelets, neutrophils, and sodium, including cyclophosphamide dose adjustment in the case of kidney disease. Cyclophosphamide is responsible for other rare - but serious - side effects, for instance, hepatotoxicity, severe hyponatremia and heart failure. Other adverse reactions include hair loss, amenorrhea and menopause. In this routine, we also entered guidelines to post-chemotherapy patients. The compatibility of injectable drugs with the vehicle used has been described, as well as stability and infusion times. The routine aimed at the rational use of cyclophosphamide, with prevention of adverse events and relapse episodes, factors that may burden the health care system.

Resumo A ciclofosfamida (CFM) é um agente alquilante vastamente usado para o tratamento de neoplasias malignas e pode ser usado no tratamento de diversas doenças reumatológicas. O erro de administração de medicamentos pode levar à diminuição da eficácia ou ao aumento da toxicidade medicamentosa. Diversos erros ocorrem na administração de medicamentos injetáveis. O trabalho objetivou a estruturação de uma rotina do uso de ciclofosfamida, bem como a criação de um documento de orientações farmacoterapêuticas para o paciente. A rotina foi esquematizada em três fases, a pré-quimioterapia (pré-QT), a administração da ciclofosfamida e a pós-quimioterapia (pós-QT), que levaram em consideração os medicamentos que devem ser administrados antes e depois da ciclofosfamida para prevenção aos efeitos adversos, incluindo náusea e cistite hemorrágica. As reações adversas podem alterar os exames laboratoriais e a rotina incluiu manejo clínico para alteração clínica dos leucócitos, das plaquetas, dos neutrófilos e do sódio incluindo o ajuste de dose de ciclofosfamida em caso de insuficiência renal. A ciclofosfamida é responsável por outras reações adversas raras, mas sérias, como hepatotoxicidade, hiponatremia severa e falência cardíaca. Outras reações adversas incluem perda de cabelo, amenorreia e menopausa. A rotina foi composta também por orientações ao paciente pós-QT. A compatibilidade dos medicamentos injetáveis com o veículo foi descrita, bem como o tempo de estabilidade e o tempo de infusão. A rotina visou ao uso racional da ciclofosfamida e prevenir os efeitos adversos e os episódios de recidiva, os quais podem onerar o sistema de saúde.
