Comparison of Efficacy and Safety of Midazolam versus Nitrous Oxide as Sedative Agents during Paediatric Dental Treatment: A Systematic Review

ABSTRACT Objective: To identify and study the existing literature on the efficacy and safety of midazolam compared to inhalation of nitrous oxide in children undergoing dental treatment. Material and Methods: Electronic resources such as PubMed Central, Cochrane Database of Systematic Reviews, Lilacs, Science Direct, and SIGLE were thoroughly searched. The title scan was used to find randomised controlled trials reviewed for inclusion by reading the abstract. Studies comparing the sedative, behavioural, and anxiolytic effects and safety in children undergoing dental treatment under midazolam and nitrous oxide inhalation were included. The Cochrane Reviews system software, Revman 5.4.1, was used to assess the quality of the included studies. Results: 11328 articles were identified by screening the electronic databases, of which 10906 were eliminated after titles were read and duplicates were removed. Ten full-text articles were examined, of which three were excluded as they did not match the eligibility criteria. Hence, a total of 7 studies were included. Midazolam and nitrous oxide inhalation were not statistically different in terms of the success of treatment and behaviour modification. However, midazolam showed a deeper level of sedation and resulted in amnesia in more children when compared to nitrous oxide sedation. All of the included studies were found to have a high risk of bias. Conclusion: Though all the studies included showed an increased risk of bias, midazolam and nitrous oxide inhalation seem equally effective sedative agents for controlling behaviour in children undergoing dental treatment. Midazolam shows a deeper sedation level when given orally and produces a higher rate of anterograde amnesia.

General anesthesia versus deep sedation for dental treatment in children: comparison of parental acceptance, oral health-related quality of life, and treatment efficacy / 南方医科大学学报

OBJECTIVE@#To compare the parental acceptance of dental treatment under general anesthesia and deep sedation in children and assess the changes in postoperative oral health-related quality of life and treatment efficacy.@*METHODS@#The parents of 131 children undergoing dental treatment in the Department of Stomatology of Sichuan Provincial People's Hospital from January, 2022 to June, 2022 were surveyed using a questionnaire of children's advanced oral behavior management, and 83 children receiving general anesthesia or deep sedation for dental treatment between January, 2018 and December, 2021 were also investigated for changes in quality of life after the treatment using a questionnaire. The treatment efficacy was assessed at the 1-year follow-up visit in 149 children who received dental treatment under general anesthesia or deep sedation during the same period.@*RESULTS@#The survey of perantal acceptance showed that 62.6% of the parents preferred deep sedation, 29.01% preferred general anesthesia, and 8.4% preferred compulsory treatment. Dental treatments under general anesthesia and deep sedation both significantly improved oral health-related quality of life of the children. While dental surgeries under general anesthesia resulted in the most significant improvement of pain symptoms, deep sedation was associated with both obvious relief of the children's pain symptoms and reduction of the parents' pressure level. No significant difference was found in the efficacy of treatments under general anesthesia and deep sedation at the 1-year follow-up.@*CONCLUSION@#Dental treatment in children under deep sedation has the highest parental acceptance, followed by treatment under general anesthesia, and the acceptance of compulsory treatment is the lowest. The treatments under general anesthesia and deep sedation significantly improve the quality of life of the children and their parents and both have good treatment efficacy.

Research progress on moderate and deep sedation during wound dressing change in pediatric burn patients / 中华烧伤杂志

Moderate and deep sedation can effectively relieve or eliminate the pain and body discomfort during wound dressing change in pediatric burn patients, relieve anxiety, agitation, and even delirium of the children, reduce the metabolic rate of the children, make them in a quiet, comfortable, and cooperative state, which is conducive to the smooth completion of dressing change. This paper summarized the three aspects of moderate and deep sedation in pediatric burn patients, including the overview, main points of implementation, and effects, and further introduced the moderate and deep sedation medication regimens for different routes of administration, as well as the content of evaluation and monitoring. Suggestions on the prevention and management of related complications and the management of moderate and deep sedation implementation procedures were put forward, in order to provide references for the development of moderate and deep sedation for wound dressing change in pediatric burn patients in China.

Pediatric procedural sedation in African clinical settings: A mixed methods study of African providers' sedation practices

Background: Little is known about the practice of pediatric procedural sedation in Africa, despite being incredibly useful to the emergency care of children. This study describes the clinical experiences of African medical providers who use pediatric proceduralsedation, including clinical indications, medications, adverse events, training, clinical guideline use, and comfort level. The goals of this study are to describe pediatric sedation practices in resource-limited settings in Africa and identify potential barriers to the provision of safe pediatric sedation. Methods: This mixed methods study describes the pediatric procedural sedation practices of African providers using semi-structured interviews. Purposive sampling was used to identify key informants working in African resource-limited settings across a broad geographic, economic, and professional range. Quantitative data about provider background and sedation practices were collected concurrently with qualitative data about perceived barriers to pediatric procedural sedation and suggestions to improve the practice of pediatric sedation in their settings. All interviews were transcribed, coded, and analyzed for major themes. Results: Thirty-eight key informants participated, representing 19 countries and the specialties of Anesthesia, Surgery, Pediatrics, Critical Care, Emergency Medicine, and General Practice. The most common indication for pediatric sedation was imaging (42%), the most common medication used was ketamine (92%), and hypoxia was the most common adverse event (61%). Despite 92% of key informants stating that pediatric procedural sedation was critical to their practice, only half reported feeling adequately trained. The three major qualitative themes regarding barriers to safe pediatric sedation in their settings were: lack of resources, lack of education, and lack of standardization across sites and providers. Conclusions: The results of this study suggest that training specialized pediatric sedation teams, creating portable "pediatric sedation kits," and producing locally relevant pediatric sedation guidelines may help reduce current barriers to the provision of safe pediatric sedation in resource-limited African settings.

Analgosedación con propofol y fentanilo en las colonoscopia / Analgosedation with propofol and fentanyl in colonoscopy

Introducción: La comodidad durante la colonoscopia es una condición importante si se quiere que el paciente acepte procedimientos repetidos. Por lo tanto, se necesita de una buena sedación que pudiera combinar la analgesia con amnesia. Objetivo: Describir la utilidad de la analgosedación balanceada con propofol/fentanilo en colonoscopia ambulatoria. Métodos: Se realizó un estudio observacional descriptivo longitudinal prospectivo en pacientes a los que se les realizó colonoscopia de forma ambulatoria en el Hospital General Universitario Dr. Gustavo Aldereguía Lima en el período entre enero de 2017 y diciembre de 2018. Resultados: El 34,2 por ciento de los pacientes tenía entre 50 y 59 años, el 62,9 por ciento eran mujeres. El 73,3 por ciento de los pacientes se clasificó como ASA II según el estado físico. Los valores medios de frecuencia cardiaca y tensión arterial media tuvieron una disminución ligera después de aplicada la anestesia y se mantuvieron constantes en el resto de los momentos evaluados. Los valores medios de saturación de oxígeno de la hemoglobina se mantuvieron relativamente constantes en todos los momentos y resultaron algo superiores a la llegada del paciente a recuperación. La calidad de la sedación fue adecuada en 86,2 por ciento de los pacientes. La calidad de la analgesia y la recuperación fue buena en 88,4 por ciento y 96,2 por ciento , respectivamente. Se presentaron complicaciones en el 16,5 por ciento de los pacientes. Conclusiones: La analgosedación con propofol y fentanilo resultó una alternativa anestésica de utilidad en los pacientes a los que se les realizó colonoscopia ambulatoria con gran estabilidad hemodinámica en la serie estudiada(AU)

Introduction: Comfort during colonoscopy is an important condition if the patient is expected to accept repeated procedures. Therefore, good sedation that could combine analgesia with amnesia is needed. Objective: To describe the usefulness of balanced analgosedation with propofol/fentanyl in outpatient colonoscopy. Methods: A prospective, longitudinal, descriptive and observational study was carried out with patients who received outpatient colonoscopy at Dr. Gustavo Aldereguía Lima General University Hospital in the period between January 2017 and December 2018. Results: 34.2 percent of the patients were between 50 and 59 years old, while 62.9 percent were women. 73.3 percent of patients were classified as ASA II, according to their physical status. The mean values for heart rate and mean arterial blood pressure had a slight decrease after anesthesia was applied and remained constant for the rest of the evaluated times. The mean values of hemoglobin-oxygen saturation remained relatively constant at all the evaluated times and were slightly higher on the patient's arrival to recovery. The quality of sedation was adequate in 86.2 percent of the patients. The quality of analgesia and recovery was good in 88.4 percent and 96.2 percent, respectively. Complications occurred in 16.5 percent of the patients. Conclusions: Analgosedation with propofol and fentanyl proved to be a useful anesthetic alternative in patients undergoing outpatient colonoscopy, with high hemodynamic stability in the studied series(AU)

Prática clínica e barreiras relacionadas à mobilização precoce em unidade de terapia intensiva / Clinical practice and barriers related to early mobilization in intensive care unit

Objetivo: caracterizar a prática clínica e identificar as barreiras relacionadas à mobilização precoce em uma Unidade de Terapia Intensiva. Método: estudo observacional analítico e prospectivo que incluiu pacientes em ventilação mecânica por mais de 24 horas. Foram coletados diariamente dados clínicos, critérios de segurança, barreiras e atividades realizadas nos atendimentos de fisioterapia. Posteriormente a amostra foi dividida de acordo com a realização de sedestação à beira do leito. Utilizou-se teste T para comparação entre grupos e para associação teste Qui-quadrado ou Exato de Fischer quando necessário. Resultados: participaram 54 indivíduos com média de idade 51,33±14,85 anos e SAPSIII médio de 63,47±13,37 pontos. A mobilização foi realizada em 1356 sessões, em sua maioria atividades passivas. Nenhuma atividade fora do leito foi realizada com pacientes em ventilação mecânica. As principais barreiras foram sedação, nível de consciência e procedimentos médicos. A não sedestação à beira do leito foi associada à ausência de critérios de segurança, que impediram a mobilização, e ocorrência de óbito. Conclusão: A mobilização foi realizada na maioria das sessões, porém poucas atividades foram realizadas fora do leito. Durante o período de ventilação mecânica nenhuma atividade foi realizada fora do leito. As barreiras mais citadas foram sedação, nível de consciência e procedimentos médicos.

Purpose: characterize the clinical practice and identify barriers related to early mobilization in an Intensive Care Unit. Method: analytical and prospective observational study that included patients on mechanical ventilation for more than 24 hours. Clinical data, safety criteria, barriers and activities performed in physical therapy consultations were collected on a daily basis. Subsequently, the sample was divided according to the performance of the patient sitting at the bedside. The T-test was used for comparison between groups and the Chi-square test or Fisher's exact test were used when necessary. Results: a total of 54 individuals participated, with a mean age of 51.33±14.85 years and mean SAPSIII of 63.47±13.37 points. Mobilization was performed in 1356 sessions, mostly passive activities. No out-of-bed activities were performed with patients on mechanical ventilation. The main barriers were sedation, level of consciousness, and medical procedures. Failure to sit at the bedside was associated with the absence of safety criteria, which prevented mobilization, and the occurrence of death. Conclusion: Mobilization was performed in most sessions, but few activities were performed outside the bed. During the period of mechanical ventilation, no activity was performed outside the bed. The barriers most frequently mentioned were sedation, level of consciousness, and medical procedures.

Uso de la sedación y anestesia en los pacientes pediátricos sometidos a radioterapia / Use of sedation and anesthesia in the pediatrics patients undergoing radiotherapy

Resumen Justificación: La radioterapia es esencial para el tratamiento del cáncer pediátrico. Al menos la mitad de los niños que requieren radioterapia van a necesitar sedación o anestesia. Es importante conocer las complicaciones potenciales asociadas con el uso repetitivo de medicamentos sedantes o anestésicos. El objetivo del estudio fue describir las características clínicas y epidemiológicas de los pacientes con diagnóstico de cáncer del Hospital Nacional de Niños "Dr. Carlos Sáenz Herrera", de la Caja Costarricense de Seguro Social, que recibieron sedación o anestesia durante su tratamiento con radioterapia externa en el período de enero del 2016 a junio del 2019. Métodos: Es un estudio observacional, descriptivo y retrospectivo de una serie de casos. Se incluyeron pacientes pediátricos con diagnóstico de cáncer, sometidos a tratamiento con radioterapia y que requirieron sedación o anestesia durante esa intervención. Las técnicas estadísticas utilizadas para las variables cualitativas fueron tablas de frecuencias simples y de asociación o contingencia; las variables cuantitativas se describen mediante estadígrafos de tendencia central y posición, así como de variabilidad. Resultados: Un total de 61 pacientes con diagnóstico de cáncer y que recibieron radioterapia fueron estudiados. El 57,4% de los pacientes fueron hombres. El 75% de los pacientes tenía 4,0 años o menos. La localización anatómica más frecuente del tumor fue en sistema nervioso central. Una minoría (14,5%) recibió como tratamiento único la radioterapia. El 75% de los pacientes recibió 30 o menos sesiones de tratamiento bajo sedación o anestesia. El propofol se suministró al 100,0% de los pacientes en todas las sesiones de tratamiento. El tiempo promedio de sedación o anestesia fue de 67,9 ± 28,2 minutos. El 34,4% de los pacientes presentaron complicaciones respiratorias, cardiovasculares o ambas, en al menos una sesión de tratamiento. Conclusiones: En los pacientes pediátricos con cáncer quienes reciben tratamiento con radioterapia, fue requerido el uso de la sedación y anestesia principalmente en niños de corta edad; en general, las complicaciones de la radioterapia fueron transitorias y usualmente bien toleradas, sin presentar morbimortalidad. Como monoterapia, el Propofol no mostró complicaciones asociadas; sin embargo, al adicionar otros fármacos sí se observaron complicaciones respiratorias y predominó la desaturación transitoria de oxígeno.

Abstract Background: Radiation therapy is essential for the treatment of pediatric cancer. At least half of the children who require radiation therapy will need sedation or anesthesia. It is important to know the potential complications associated with repetitive use of sedative or anesthetic medications. The objective of the study was to describe the clinical and epidemiological characteristics of patients diagnosed with cancer at the National Children's Hospital "Dr. Carlos Sáenz Herrera" of the Costa Rican Social Security Fund, who received sedation or anesthesia during their treatment with external radiotherapy in the period from January 2016 to June 2019. Methods: It is an observational, descriptive and retrospective study of a series of cases. Pediatric patients diagnosed with cancer, who underwent radiotherapy treatment and who required sedation or anesthesia during that intervention were included. The statistical techniques used for the qualitative variables were simple frequency tables and association or contingency tables; quantitative variables are described using central tendency and position statistics, as well as variability. Results: A total of 61 patients diagnosed with cancer and receiving radiotherapy were studied. 57.4% of the patients were men. 75% of patients were 4.0 years or younger. The most frequent anatomic location of the tumor was in the central nervous system. A minority (14.5%) received radiotherapy as the only treatment. 75% of patients received 30 or fewer treatment sessions under sedation or anesthesia. Propofol was administered to 100.0% of patients in all treatment sessions. The average sedation or anesthesia time was 67.9 ± 28.2 minutes. 34.4% of the patients presented respiratory or cardiovascular complications, or both, in at least onetreatment session. Conclusions: In pediatric patients diagnosed with cancer, the use of sedation and anesthesia during radiotherapy treatment was required mainly in young children and in moderate frequency, the complications of the radiation therapy were temporary and usually well tolerated, without presenting morbidity and mortality. Propofol as monotherapy turned out to have no associated complications, however, when other drugs were added, adverse effects were observed in respiratory system, the most frequent being transient oxygen desaturation.

Effects of remifentanil on awakening of propofol sedated patients submitted to upper gastrointestinal endoscopy: a randomized clinical trial / Efeitos do remifentanil sobre despertar de pacientes sedados com propofol para endoscopia digestiva alta: estudo clínico randomizado

Abstract Background and objectives: Sedation for endoscopic procedures aims to provide high quality sedation, lower risks, short recovery time, superior recovery quality and absence of side effects, seeking high patient level of satisfaction. The goal of the study was to assess administration of remifentanil combined with propofol regarding the effects of the drug association during sedation and recovery for patients submitted to upper gastrointestinal diagnostic endoscopy. Method: One hundred and five patients were assessed, randomly divided into three groups of 35 patients. The Control Group was sedated with propofol alone. Study Group 1 was sedated with a fixed dose of 0.2 µg.kg−1 remifentanil combined with propofol. Study Group 2 was sedated with 0.3 µg.kg−1 remifentanil combined with propofol. We assessed the quality of sedation, hemodynamic parameters, incidence of significant hypoxemia, time for spontaneous eye opening, post-anesthetic recovery time, quality of post-anesthetic recovery, presence of side effects and patient satisfaction. Results: Study Group 1 showed better quality of sedation. The groups in which remifentanil was administered combined with propofol showed shorter eye-opening time and shorter post-anesthetic recovery time compared to the control group. The three groups presented hemodynamic changes at some of the moments assessed. The incidence of significant hypoxemia, the quality of post-anesthetic recovery, the incidence of side effects and patient satisfaction were similar in the three groups. Conclusions: The combination of propofol with remifentanil at a dose of 0.2 µg.kg−1 was effective in improving the quality of sedation, and at doses of 0.2 µg.kg−1 and 0.3 µg.kg−1 reduced the time to spontaneous eye opening and post-anesthetic recovery in comparison to sedation with propofol administered alone.

Resumo Justificativa e objetivos: A sedação para procedimentos endoscópicos pretende fornecer boa qualidade de sono, menores riscos, tempo de recuperação mais curto, qualidade de recuperação superior e ausência de efeitos colaterais, buscando um elevado nível de satisfação dos pacientes. O objetivo deste estudo foi avaliar a influência da associação do remifentanil ao propofol e seus efeitos durante a sedação e a recuperação em exames de endoscopia digestiva alta diagnóstica. Método: Foram avaliados 105, divididos aleatoriamente em três grupos de 35 pacientes. O Grupo Controle foi sedado apenas com o uso de propofol, o Grupo de Estudo 1 foi sedado com uso de remifentanil em dose fixa de 0,2 µg.Kg-1 associado ao propofol. E o Grupo de Estudo 2 foi sedado com o uso de remifentanil em dose fixa de 0,3 µg.Kg-1 associado ao propofol. Foram avaliadas a qualidade da sedação, comportamento hemodinâmico, incidência de hipoxemia significativa, tempo para abertura ocular espontânea, tempo de recuperação pós-anestésica, qualidade da recuperação pós-anestésica, presença de efeitos colaterais e satisfação do paciente. Resultado: O Grupo de Estudo 1 apresentou melhor qualidade de sedação. Os grupos em que se associou o remifentanil apresentaram tempo para abertura ocular e tempo de recuperação anestésica mais curtos em relação ao grupo controle. Os três grupos apresentaram alterações hemodinâmicas em algum dos momentos avaliados. A incidência de hipoxemia significativa, a qualidade da recuperação pós-anestésica, a incidência de efeitos colaterais e a satisfação dos pacientes foram similares nos três grupos. Conclusão: Conclui-se que a associação do remifentanil na dose de 0,2 µg.kg-1 mostrou-se efetivo na melhora da qualidade da sedação, e nas doses 0,2 µg.kg-1 e de 0,3 µg.kg-1 reduziu o tempo de abertura ocular espontânea e o tempo de recuperação pós-anestésica dos pacientes em relação a sedação apenas com propofol.

Practices related to assessment of sedation, analgesia and delirium among critical care pediatricians in Brazil / Práticas relacionadas à avaliação de sedação, analgesia e delirium entre pediatras intensivistas no Brasil

ABSTRACT Objective To understand the use of tools, protocols and comfort measures related to sedation/analgesia, and to screen the occurrence of delirium in pediatric intensive care units. Methods A survey with 14 questions was distributed by e-mail to Brazilian critical care pediatricians. Eight questions addressed physician and hospital demographics, and six inquired practices to assess sedation, analgesia, and delirium in pediatric intensive care units. Results Of 373 questionnaires sent, 61 were answered (16.3%). The majority of physicians were practicing in the Southeast region (57.2%). Of these, 46.5% worked at public hospitals, 28.6% of which under direct state administration. Of respondents, 57.1% used formal protocols for sedation and analgesia, and the Ramsay scale was the most frequently employed (52.5%). Delirium screening scores were not used by 48.2% of physicians. The Cornell Assessment of Pediatric Delirium was the score most often used (23.2%). The majority (85.7%) of physicians did not practice daily sedation interruption, and only 23.2% used non-pharmacological measures for patient comfort frequently, with varied participation of parents in the process. Conclusion This study highlights the heterogeneity of practices for assessment of sedation/analgesia and lack of detection of delirium among critical care pediatricians in Brazil.

RESUMO Objetivo Compreender o uso de ferramentas, protocolos e medidas de conforto relacionadas à sedação/analgesia, além de rastrear a presença de delirium em unidades de terapia intensiva pediátricas. Métodos Um inquérito com 14 questões foi distribuído, por meio de correio eletrônico, para médicos pediatras intensivistas brasileiros. Oito questões eram sobre os dados demográficos dos médicos e dos hospitais, e seis questões eram sobre as práticas na avaliação da sedação, analgesia e delirium em unidades de terapia intensiva pediátrica. Resultados Responderam ao inquérito 61 médicos dos 373 e-mails enviados (taxa de resposta de 16,3%). A maioria dos médicos era da Região Sudeste (57,2%) e 46,5% trabalhavam em hospitais públicos, sendo 28,6% sob administração direta do Estado. Dos respondedores, 57,1% utilizavam protocolos formais de sedação e analgesia, sendo a escala de Ramsay a mais utilizada (52,5%). Não utilizavam escores de rastreamento de delirium 48,2% dos médicos, e o Cornell Asssessment of Pediatric Delirium (23,2%) foi o mais utilizado. A maioria (85,7%) dos médicos não utilizou a prática da interrupção diária da sedação, e apenas 23,2% utilizavam medidas não farmacológicas para o conforto do paciente com frequência, com a participação heterogênea dos pais nesse processo. Conclusão Este estudo destaca a heterogeneidade nas práticas de avaliação da sedação/analgesia e insuficiência de rastreamento de delirium entre os intensivistas pediátricos brasileiros.

Objective: To analyze the relationship between the factors of the patient, the nursing professional and the institution with the achievement of a sedoanalgesia objective in an ICU for adults in Medellín, Colombia. Methodology: Quantitative, descriptive, cross-sectional, correlational study, carried out with 79 adult patients from an ICU of an Institution of Medellín (ANT), during 6 months between 2019 and 2020. Medical records of the patients were reviewed to analyze the independent variables : nutritional status, kidney function, level of adherence to the institutional sedoanalgesia protocol by nursing professionals, workload; and the dependent variable: achievement of the sedoanalgesia objective, and, if a statistical association was found between the variables through the application of the Spearman correlation coefficient. Results: 86% of the patients obtained a high nutritional risk according to NUTRIC. 53.4% of the total male patients and 19.4% of the female gender had a creatinine level higher than normal. 56.9% of the patients had a lower than normal GFR. In 94% of the patients, a high level of adherence to the protocol was found by the nursing staff. 96% of the patients had a grade IV according to the TISS-28 classification. 57% of the patients reached the goal of sedoanalgesia. We found a weak positive association (0.263) statistically significant (p = 0.019) between the NUTRIC variable with the achievement of the sedoanalgesia goal. Conclusions: There is a relationship between the nutritional status and the achievement of a sedoanalgesia goal. (AU)

Associação entre achados eletromiográficos e mortalidade na unidade de terapia intensiva em pacientes com síndrome do desconforto respiratório agudo mecanicamente ventilados sob sedação profunda / Association between electromyographical findings and intensive care unit mortality among mechanically ventilated acute respiratory distress syndrome patients under profound sedation

RESUMO Objetivo: Avaliar se os achados eletromiográficos podem prever a mortalidade na unidade de terapia intensiva em pacientes sépticos sob ventilação mecânica e sedação profunda. Métodos: Conduziu-se estudo prospectivo de coorte, que inscreveu, de forma consecutiva, pacientes com síndrome do desconforto respiratório agudo moderada a grave (pressão parcial de oxigênio/fração inspirada de oxigênio < 200) com idade ≥ 18 anos, dependentes de ventilação mecânica por 7 ou mais dias, e mantidos sob sedação profunda (escala de agitação e sedação de Richmond ≤ -4). Realizaram-se estudos eletromiográficos dos membros inferiores em todos os pacientes entre o sétimo e o décimo dia de ventilação mecânica. Registraram-se os potenciais de ação dos nervos sensitivos nos nervos mediano e sural, bem como os potenciais de ação compostos para os nervos mediano (músculo abdutor curto do polegar) e fibular comum (músculo extensor curto dos dedos). Resultados: Foram inscritos 17 pacientes durante os 7 meses de duração do estudo. Nove pacientes (53%) tinham sinais eletromiográficos de miopatia ou polineuropatia da doença crítica. O risco de óbito durante o tempo de permanência na unidade de terapia intensiva foi mais elevado nos pacientes com sinais eletromiográficos de miopatia ou polineuropatia da doença crítica, em comparação com aqueles sem esses diagnósticos (77,7% versus 12,5%; log-rank p = 0,02). Conclusão: A presença de sinais eletromiográficos de miopatia ou polineuropatia da doença crítica, entre o sétimo e décimo dias de ventilação mecânica, pode se associar com mortalidade na unidade de terapia intensiva em pacientes com síndrome do desconforto respiratório agudo moderada a grave mantidos sob sedação profunda, nos quais não é possível proceder à avaliação clínica da força muscular.

ABSTRACT Objective: To evaluate whether electromyographical findings could predict intensive care unit mortality among mechanically ventilated septic patients under profound sedation. Methods: A prospective cohort study that consecutively enrolled moderate-severe acute respiratory distress syndrome (partial pressure of oxygen/fraction of inspired oxygen < 200) patients who were ≥ 18 years of age, dependent on mechanical ventilation for ≥ 7 days, and under profound sedation (Richmond Agitation Sedation Scale ≤ -4) was conducted. Electromyographic studies of the limbs were performed in all patients between the 7th and the 10th day of mechanical ventilation. Sensory nerve action potentials were recorded from the median and sural nerves. The compound muscle action potentials were recorded from the median (abductor pollicis brevis muscle) and common peroneal (extensor digitorum brevis muscle) nerves. Results: Seventeen patients were enrolled during the seven months of the study. Nine patients (53%) had electromyographic signs of critical illness myopathy or neuropathy. The risk of death during the intensive care unit stay was increased in patients with electromyographical signs of critical illness myopathy or neuropathy in comparison to those without these diagnostics (77.7% versus 12.5%, log-rank p = 0.02). Conclusion: Electromyographical signs of critical illness myopathy or neuropathy between the 7th and the 10th day of mechanical ventilation may be associated with intensive care unit mortality among moderate-severe acute respiratory distress syndrome patients under profound sedation, in whom clinical strength assessment is not possible.

Hormonas sexuales en la enfermedad crítica / Sexual hormones in critical disease

INTRODUCCIÓN. En el paciente crítico ha existido un conglomerado de situaciones dadas por alteración de las hormonas acorde al comportamiento del eje hipotalámi-co-hipofisario- gonadal, entender su rol es fundamental. OBJETIVO. Describir las alteraciones de las hormonas sexuales en el paciente críticamente enfermo desde un enfoque fisiológico y clínico. MATERIALES Y MÉTODOS. Estudio observacional, de revisión bibliográfica y análisis sistemático de 84 artículos científicos y selección de muestra de 27 en MedLine, The Cochrane Library Plus, LILACS y Web of Science; en español e inglés y variables: hormonas esteroides gonadales, enfermedad crítica, endocrinología, estrés, gónadas y disfunción, periodo 1998-2017. CONCLUSIÓN. Las alteraciones detectadas fueron un mecanismo para la producción de hormonas esteroideas hacia la síntesis predominante de cortisol y soportar el alto estrés meta-bólico de los pacientes. Las citocinas pro inflamatorias fueron importantes en éstos cambios. La polifarmacia fue un factor adicional poco ponderado de la alteración endocrina sexual.

INTRODUCTION. In the critical patient there has been a conglomerate of situations given by alteration of the hormones according to the behavior of the hypothalamic-pi-tuitary-gonadal axis, understanding their role is fundamental. OBJECTIVE. Describe the alterations of sex hormones in the critically ill patient from a physiological and clinical approach.MATERIALS AND METHODS.Observational, literature review and systematic analysis of 84 scientific articles and sample selection of 27 in MedLine, The Cochrane Library Plus, LILACS and Web of Science; in Spanish and English and variables: gonadal steroid hormones, critical illness, endocrinology, stress, gonads and dysfunction, period 1998-2017. CONCLUSION. The alterations detected were a mechanism for the production of steroid hormones towards the predominant syn-thesis of cortisol and withstand the high metabolic stress of the patients. Pro inflam-matory cytokines were important in these changes. Polypharmacy was an additional unweighted factor of sexual endocrine disruption.

Monitorización automática de estados de sedación en señales electroencefalográficas / Automatic monitoring of sedation states in electroencephalographic signals

La anestesia general proporciona al paciente estados de inconciencia, amnesia y analgesia, sin embargo, se reportan casos de despertar intraoperatorio. Debido a la incidencia de este fenómeno y sus efectos psicosomáticos, el Centro de Estudios de Neurociencias, Procesamiento de Imágenes y Señales en la Universidad de Oriente, y el Hospital General Juan Bruno Zayas Alfonso ambos en Santiago de Cuba, Cuba, implementan una metodología que permita detectar automáticamente estados de sedación anestésica aplicando Inteligencia Artificial. Para esto se emplearon las señales registradas por el canal electroencefalográfico F4, nueve parámetros espectrales, las Máquinas de Soporte Vectorial y los Sistemas Neuro-Difusos. En el reconocimiento automático de los estados de Sedación Profunda, Moderada y Ligera se logró una Exactitud de 96.12 por ciento, 90.06 por ciento y 90.24 por ciento respectivamente con las Máquinas de Soporte Vectorial, por lo que se propone el uso del canal electroencefalográfico F4 en la detección de estados anestésicos(AU)

General anesthesia provide the patient states of unconsciousness, amnesia and analgesia, however, cases of intraoperative awareness are reported. Due to the incidence of this phenomenon and the psychosomatic effects it causes, the Neuroscience Studies Center, Images and Signals Processing at the University of Oriente, and the General Hospital Juan Bruno Zayas Alfonso both in Santiago de Cuba, Cuba, implement a methodology that allows the automatic detection of anesthetic sedation states applying Artificial Intelligence. For this, the signals recorded by the electroencephalographic channel F4, nine spectral parameters, the Support Vector Machines and the Neuro-Fuzzy Systems were used. In the automatic recognition of the Sedation States: Profound, Moderate and Mild an Accuracy of 96.12 percent, 90.06 percent and 90.24 percent respectively was achieved with the Support Vector Machines, so the use of the electroencephalographic channel F4 is proposed in the detection of anesthetic states(AU)
