ABSTRACT Objective: The main objective of this study was to compare stress and anxiety levels in children undergoing surgical procedures with or without parental presence at induction of anesthesia by measuring salivary cortisol levels and applying the mYPAS. Method: Quasi-randomized trial with children aged 5–12 year, with ASA physical status I, II, or III, undergoing elective surgery. According to parents’ willingness, the pair were defined as accompanied or unaccompanied group. Chi-square, Fisher’s exact tests, Student’s t test, Mann-Whitney, Hodges-Lehman and Spearman’s tests were used for statistical analyzes. Results: We included 46 children; 63% were preschool children mostly accompanied by their mothers (80%). The median mYPAS score was 37.5 (quartile range, 23.4–51.6) in unaccompanied children, and 55.0 (quartile range, 27.9–65.0) in accompanied children, with an estimated median difference of +11.8 (95% CI of 0 to 23.4; p = 0.044). There were no significant differences in the mean salivary cortisol levels. Conclusion: The level of anxiety was higher in accompanied children. There were no differences in salivary cortisol levels between both groups. Brazilian Registry of Clinical Trials (ReBEC):RBR-9wj4qvy.

Abstract Difficult airway management in pediatrics during anesthesia represents a major challenge, requiring a careful approach, advanced technical expertise, and accurate protocols. The task force of the Brazilian Society of Anesthesiology (SBA) presents a report containing updated recommendations for the management of difficult airways in children and neonates. These recommendations have been developed based on the consensus of a panel of experts, with the objective of offering strategies to overcome challenges during airway management in pediatric patients. Grounded in evidence published in international guidelines and expert opinions, the report highlights crucial steps for the appropriate management of difficult airways in pediatrics, encompassing assessment, preparation, positioning, pre-oxygenation, minimizing trauma, and, paramountly, the maintenance of arterial oxygenation. The report also delves into additional strategies involving the use of advanced tools, such as video laryngoscopy, flexible intubating bronchoscopy, and supraglottic devices. Emphasis is placed on the simplicity of implementing the outlined recommendations, with a focus on the significance of continuous education, training through realistic simulations, and familiarity with the latest available technologies. These practices are deemed essential to ensure procedural safety and contribute to the enhancement of anesthesia outcomes in pediatrics. challenge approach expertise protocols SBA (SBA neonates experts patients opinions assessment preparation positioning preoxygenation, preoxygenation pre oxygenation, oxygenation pre-oxygenation trauma paramountly tools laryngoscopy bronchoscopy devices education simulations technologies

Abstract The International Association for the Study of Pain chose pain prevention as the theme for the 2020 Global Year. Chronic postoperative pain is one the many types of pain that can be potentially prevented. It develops or increases in severity after a surgery, persists for at least three months, even after ruling out all other possible causes of pain. To perform the present narrative review, the authors searched the PubMed database using the following keywords “postoperative pain” OR “postsurgical pain” AND “chronic” OR “persistent”. The present review focused on the incidence, pain development and chronification, and predisposing factors. It also discusses prevention, diagnosis, and treatment of chronic postoperative pain. Awareness of occurrence of chronic postoperative pain and recognizing risk factors is crucial for the day-to-day practice of the anesthesiologist. Hence, numerous surgical patients can have their outcome improved by preventing chronic postoperative pain, a condition scarcely identified and without a well-established treatment.

Abstract Background and aims: Rocuronium may provide excellent onset time, but high doses are required for effective action. Several strategies have managed to shorten rocuronium onset time, including the use of Magnesium Sulphate (MgSO4). Methods: One hundred and eighty patients were randomized into six groups according to rocuronium dose received (0.3, 0.6 or 1.2 mg.kg-1) and the administration of saline or MgSO4 (60 mg.kg-1). Correlations between tissue perfusion and rocuronium onset time was determined by variations in perfusion index. Results: Median (quartiles) rocuronium onset times were 85.5 (74.0–92.0); 76.0 (52.0–87.0) and 50.0 (41.0–59.5) seconds for 0.3, 0.6 mg.kg-1 and 1.2 mg.kg-1 doses, respectively. MgSO4 decreased rocuronium onset at doses of 0.3 mg.kg-1 (60.0 [48.0–74.3] seconds) and 0.6 mg.kg-1 (44.0 [39.0–49.0] seconds) but not at 1.2 mg.kg-1 (38.0 [33.5–56.3] seconds) (p< 0.001). Perfusion index variations in groups that received MgSO4 were greater than in controls. A negative correlation between shorten onset and increased perfusion index was observed in rocuronium doses of 0.3 mg.kg-1 (r = -0.50; p < 0.001) and 0.6 mg.kg-1 (r = -0.424; p< 0.001), but not for 1.2 mg.kg-1 dose (r = -0.25; p = 0.07). Conclusion: MgSO4 reduces rocuronium onset time at doses of 0.3 mg.kg-1 and 0.6 mg.kg-1 being that the latter has a similar effect when compared to the dose of 1.2 mg.kg-1, with or without the use of MgSO4.

Resumo Justificativa e objetivos: Os avanços da medicina, incluindo a anestesiologia e reanimação, têm tornado cada vez mais rara a ocorrência da morte natural. Como consequência, as práticas de distanásia se tornaram habituais em uma realidade que não mais se justifica. Este estudo objetiva avaliar o conhecimento de anestesiologistas brasileiros dos institutos da distanásia e ortotanásia. Para tal, investigamos as preferências de condutas desses profissionais, dentre aquelas práticas, bem como a contribuição da graduação médica na abordagem das questões relacionadas à morte. Método: Coorte prospectivo, descritivo, com abordagem quantitativa, com a inclusão de 150 anestesiologistas inscritos na Sociedade Brasileira de Anestesiologia e que foram convidados a participar por mensagem de e-mail. Aplicou-se questionário online, contendo 38 questões, elaborado pelos pesquisadores. A pesquisa foi aprovada pela Comissão de Ética em Pesquisa instrucional. Resultados: Os anestesiologistas, embora afirmem conhecer a distanásia e a ortotanásia, em sua maioria adquiriram esse conhecimento fora da graduação. Diante da terminalidade do próprio entrevistado, do seu paciente ou de um ente querido, prefere a ortotanásia, a morte em casa, priorizando a dignidade. Entretanto, esses especialistas afirmam já terem praticado, contrariados, a distanásia, mesmo quando a ortotanásia era a melhor conduta, o que lhes gerou sentimentos negativos. Quase a integralidade dos entrevistados afirmou não ter tido, na graduação, treinamento prático de conduta frente à terminalidade, embora se sinta capaz de identificá-la. A maioria não conhece a Resolução do Conselho Federal de Medicina 1.805/06 que viabiliza a prática da ortotanásia. Não há influência da religião e da região político-administrativa de residência do anestesiologista sobre as suas preferências. Conclusões: Os anestesiologistas afirmam ter conhecimento sobre distanásia e ortotanásia e preferem, diante da terminalidade, praticar a ortotanásia, embora a distanásia seja habitual, o que resulta em frustração e indignação. O ensino da graduação médica é deficitário em questões relacionadas à morte.

Abstract Background and objectives: Advances in medicine, including anesthesiology and resuscitation, have made natural death increasingly rare. As a consequence, dysthanasia has become usual in a scenario for which there is not rationale. The present study aimed to assess the level of knowledge of Brazilian anesthesiologists on the principles of dysthanasia and orthothanasia. Thence, we studied the management preferences of these professionals, vis-à-vis those practices, as well as how medical school contributed to addressing death-related issues. Method: Quantitative approach, prospective and descriptive cohort that included 150 anesthesiologists, members of the Brazilian Society of Anesthesiology, and who were invited to participate by email. An online questionnaire containing 38 questions was prepared by the authors. The study was approved by the Instructional Research Ethics Committee. Results: Anesthesiologists, although claiming to know dysthanasia and orthothanasia, mostly acquired knowledge outside medical school. If faced with their own end of care, or of a patient or a loved one, they prefer orthothanasia, to die at home, prioritizing dignity. However, the specialists claimed to have already practiced dysthanasia, even when orthothanasia was the choice management, which caused them negative feelings. Almost all respondents stated that they did not have practical training in undergraduate school on how to face end-of-life issues, although they felt capable of identifying it. Most were not aware of the Brazilian Federal Council of Medicine Resolution 1.805/06 that makes practicing orthothanasia feasible. Anesthesiologists’ religion or the political-administrative region of residence had no effect on their preferences. Conclusions: Anesthesiologists claim to have knowledge on dysthanasia and orthothanasia, but prefer, in the face of a terminally ill patient, to practice orthothanasia, although dysthanasia is usual, and results in frustration and indignation. The medical school curriculum is unsatisfactory in addressing death-related issues.

Resumo Justificativa e objetivos: Há poucos dados na literatura que caracterizam o padrão de uso de analgésicos na América Latina e no Brasil. Também se sabe pouco sobre o subtratamento da dor e sua influência no hábito de automedicação analgésica. O objetivo desta pesquisa é definir o padrão de uso de analgésicos entre os portadores de dor crônica (DC) e a sua potencial associação à automedicação analgésica. Método: Estudo observacional transversal com amostra de população urbana. A dor crônica foi definida como aquela presente por pelo menos 90 dias. A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa institucional. Resultados: Foram incluídos 416 indivíduos; 45,7% (n = 190) portadores de dor crônica, sendo os do sexo feminino (72,3%; p = 0,04) os mais acometidos. A automedicação analgésica é praticada por 78,4% dos portadores de dor crônica. O tratamento analgésico vigente mais frequente é composto pelos anti-inflamatórios não esteroides (AINES), dipirona e paracetamol. Os opioides fracos são pouco usados e apenas 2,6% dos indivíduos com dor crônica fazem uso desses analgésicos. Nenhum dos indivíduos estava em uso de opioides potentes. Conclusões: A prática de automedicação analgésica é frequente entre os portadores de dor crônica, o que pode ser consequência da pouca prescrição de analgésicos mais potentes, como os opioides. Pode-se também dizer que, pelos dados apresentados, não ocorre uma crise de uso recreativo de opioides na população estudada.

Abstract Background and objectives: There are few data in the literature characterizing the pattern of analgesic use in Latin American countries, including Brazil. Little is known about the undertreatment of pain and its influence on the habit of self-medication with analgesics. The aim of this study is to define the pattern of analgesic use among chronic pain patients and its potential association with self-medication with analgesics. Method: Cross-sectional observational study with an urban population sample. Chronic pain was defined as a pain lasting for at least 90 days. The study was approved by the Research Ethics Committee of the institution. Results: 416 subjects were included; 45.7 % (n = 190) had chronic pain, with females (72.3 %; p = 0.04) being the most affected. Self-medication with analgesics is practiced by 78.4% of patients with chronic pain. The most common current analgesic treatment consists of non-steroidal anti-inflammatory drugs (dipyrone and acetaminophen). Weak opioids are rarely used and only 2.6% of subjects with chronic pain were taking these analgesics. None of the subjects were taking potent opioids. Conclusions: The practice of self-medication with analgesics is frequent among patients with chronic pain, which may be due to the underprescription of more potent analgesics, such as opioids. It can also be said that, given the data presented, there is no crisis of recreational opioid use in the studied population.

Resumo Objetivo: Existem inúmeros protocolos de comunicação de más notícias; porém, nenhum método na literatura nacional é culturalmente adequado à nossa realidade. Este estudo propõe um método de comunicação adaptado e avalia sua aceitação entre médicos e enfermeiros brasileiros. Método: Trata-se de um estudo prospectivo cujos dados foram coletados após treinamentos específicos de médicos e enfermeiros sobre as técnicas de comunicação de más notícias. Foi empregado instrumento mnemônico chamado Protocolo P-A-C-I-E-N-T-E. Esse instrumento, em concordância com a realidade brasileira, foi baseado no Protocolo SPIKES de comunicação. Resultados: Verificou-se, entre os profissionais da saúde, que a pior tarefa a ser executada durante a comunicação é "falar sobre a morte", seguida de "discutir o fim das tentativas de tratamento curativo" e o "diagnóstico" em si. Do total dos entrevistados, 48% relataram não terem recebido treinamento formal sobre comunicações. Verificou-se, ainda, que 52% dos participantes não utilizam qualquer abordagem sistematizada na prática diária ao se comunicarem com os pacientes, mas 97% consideraram o protocolo proposto útil e adequado. Conclusão: O Protocolo P-A-C-I-E-N-T-E, proposto como ferramenta para direcionar a comunicação, mostrou-se adequado à nossa realidade.

Summary Objective: There are plenty of published tools for breaking bad medical news; however, none of them is culturally appropriate to our reality or published in the Brazilian literature. This study proposes a genuinely Brazilian communication tool and evaluates its acceptance among doctors and nurses. Method: This was a prospective study. The data were collected after specific training of doctors and nurses on the bad news communication techniques based on the P-A-C-I-E-N-T-E ("patient," in Portuguese) Protocol. This instrument is in accordance with the Brazilian reality and was based on the SPIKES communication tool. Results: The worst task to be performed during communication is "talking about death" followed by "discussing the end of curative treatment attempts" and "diagnosis" itself. Among the respondents, 48% reported they did not receive formal training for communicating. Also, 52% of respondents do not use any systematic approach in their daily practice when communicating with patients, but 97% considered the proposed P-A-C-I-E-N-T-E Protocol as a useful and appropriate communication tool. Conclusion: The P-A-C-I-E-N-T-E Protocol proved to be suitable to the Brazilian context.

PURPOSE: To evaluate the effect of parecoxib (an NSAID) on renal function by measuring plasma NGAL (serum neutrophil gelatinase-associated lipocalin) levels in an induced-ischemia rat model.METHODS: Forty male Wistar rats were randomly assigned to one of four groups: Ischemia (I), Ischemia/parecoxib (IP), No-ischemia (NI), and No-ischemia/parecoxib (NIP). Body weight, mean arterial pressure, heart rate, body temperature, NGAL levels, and renal histology were compared across groups.RESULTS: The Ischemia (I) group, which did not receive parecoxib, showed the highest NGAL levels (p=0.001), while the IP group, which received the medication, had NGAL levels similar to those of the non-ischemic (NI and NIP) groups.CONCLUSION:Parecoxib resulted in renal protection in this experimental model.

O herpes zoster pode resultar em neuralgia pós-herpética, que é definida como dor prolongada predominantemente mediada por hiperatividade do sistema nervoso central. Esse fenômeno pode ser revertido pelo uso da (S)-cetamina, mas seu uso pode resultar em efeitos adversos intoleráveis, enquanto seu uso tópico parece ser seguro. Este é um estudo "cross-over" com 12 pacientes distribuídos aleatoriamente em dois grupos. Observou-se efeito importante do tempo sobre a intensidade da dor, mas não houve diferenças estatísticas do uso da SKET, ou do placebo, no escore da dor, neste esquema de tratamento. Discretas reações cutâneas foram observadas com o uso de SKET tópico.

Herpes zoster infection may cause postherpetic neuralgia, which is defined by prolonged pain predominantly mediated by central nervous system hypersensitivity. This phenomenon may be reversed by (S)-ketamine (SKET), but its use results in intolerable side effects, while its topical administration seems to be safe. It is a cross-over design study with 12 patients randomly divided into two groups. There was a significant effect of time on pain intensity, but no statistical difference in pain scores for SKET or placebo use in this sample in this treatment regimen. Only few mild cutaneous reactions were observed with topical SKET use.
