As reações adversas frente ao uso de analgésicos e sedativos em cuidados intensivos pediátricos: implicações para a enfermagem / Adverse reactions to the use of analgesics and sedatives in pediatric intensive care: implications for Nursing

A pouca sedação em Unidades de Terapia Intensiva Pediátrica (UTIP) pode gerar estresse psicológico e físico desnecessário, além de extubação acidental. Em contrapartida, a super sedação pode provocar o uso da ventilação mecânica prolongada, levando ao maior tempo de internação dentro da UTIP, além de síndrome de abstinência, tolerância e delírio. Neste sentido, delimitou-se como objeto de estudo a identidade do cuidado de enfermagem frente às reações adversas do uso de analgésicos e sedativos nas crianças gravemente doentes. Os objetivos são: descrever as reações adversas do uso de sedativos e analgésicos identificadas pela equipe de enfermagem; analisar a prática do cuidado da equipe de enfermagem frente às reações adversas do uso de sedativos e analgésicos nas crianças; e discutir as implicações da prática do cuidado da enfermagem prestada à criança que apresenta reações adversas no uso de analgésicos e sedativos. Trata-se de um estudo de abordagem qualitativa. Foram entrevistados 15 membros da equipe de enfermagem que trabalhavam em uma UTIP de um hospital especializado em doenças crônicas e raras, utilizando-se a técnica de entrevista, o formulário de caracterização dos participantes, o diário de campo para observação não participante e a coleta de informações nos prontuários. Contou-se com o apoio do software Iramuteq para realizar a Análise Textual Discursiva. Obteve-se que as principais reações adversas identificadas pelos profissionais de enfermagem foram irritabilidade, choro e agitação. A prática do cuidado de enfermagem é desenvolvida de acordo com as reações adversas previamente identificadas e varia conforme profissional de enfermagem que atende a criança, não existindo um padrão institucional pré-estabelecido. Entre os cuidados descritos estão: banho momo, administração de doses fracionadas de sedação segundo a prescrição médica e acalento pelo familiar responsável ou pelo próprio profissional. No entanto, não foram observados registros no prontuário acerca dessas reações adversas, bem como desses cuidados relatados. Destaca-se que existe insegurança por parte da equipe de enfermagem no que tange os seus conhecimentos sobre as reações adversas relacionadas ao uso de sedativos e analgésicos e, como implicações para a prática, a falta de identidade no seu cuidado interferindo em sua autonomia e protagonismo profissional, sendo a figura do médico percebida como o mais atuante nessa temática. Conclui-se que a equipe de enfermagem reconhece alguns sinais e sintomas das reações adversas no uso de sedativos e analgésicos. Todavia, se faz necessário um aprimoramento e atualizações frente à utilização desses medicamentos, suas reações adversas e cuidados que devem ser prestados, de modo a reconhecer sua atuação e perceber sua posição dentro da equipe multiprofissional.

Inadequate sedation in Pediatric Intensive Care Units (PICU) can generate unnecessary psychological and physical stress, in addition to accidental extubating. On the other hand, oversedation can lead to the use of prolonged mechanical ventilation, leading to longer hospitalization in the PICU in addition to withdrawal syndrome, tolerance, and delirium. In this sense, the identity of nursing care in the face of adverse reactions from the use of analgesics and sedatives in seriously ill children was defined as the object of study. The objectives are to describe the adverse reactions caused using sedatives and analgesics identified by the nursing team; analyze the care practice of the nursing team in the face of adverse reactions from the use of sedatives and analgesics in children; and discuss the implications of nursing care practice provided to children who present adverse reactions to the use of analgesics and sedatives. This is a qualitative study. Fifteen members of the nursing team who worked in a PICU of a hospital specializing in chronic and rare diseases were interviewed, using the interview technique, the participant characterization form, the field diary for non-participant observation and data collection. information in medical records. The Iramuteq software was supported, and discursive textual analysis was used. It was found that the main adverse reactions identified by nursing professionals were irritability, crying and agitation. The practice of nursing care is developed according to previously identified adverse reactions and varies depending on the nursing professional who cares for the child, and there is no pre-established institutional standard. Among the care described are warm bath, administration of fractional doses of sedation according to medical prescription and comfort by the responsible family member or by the professional himself, however, no records were observed in the medical records regarding these adverse reactions, as well as this reported care. It is noteworthy that there is insecurity on the part of the nursing team regarding their knowledge about adverse reactions related to the use of sedatives and analgesics and, as implications for practice, the lack of identity in their care, interfering with their autonomy and protagonism professional, with the doctor being perceived as the most active on this topic. It is concluded that the nursing team recognizes some signs and symptoms of adverse reactions in the use of sedatives and analgesics, however, improvement and updates are necessary regarding the use of these medications, their adverse reactions and the care that must be provided to recognize their performance and understand their position within the multidisciplinary team.

Una mala sedación en las Unidades de Cuidados Intensivos Pediátricos (UCIP) puede generar estrés psicológico y físico innecesario, además de extubaciones accidentales. Por otro lado, la sobresedación puede llevar al uso de ventilación mecánica prolongada, provocando una hospitalización más prolongada en la UCIP además de síndrome de abstinencia, tolerancia y dehrio. En este sentido, se definió como objeto de estudio la identidad del cuidado de enfermería ante las reacciones adversas por el uso de analgésicos y sedantes en niños gravemente enfermos. Los objetivos son: describir las reacciones adversas provocadas por el uso de sedantes y analgésicos identificadas por el equipo de enfermería; analizar la práctica de cuidados del equipo de enfermería ante las reacciones adversas por el uso de sedantes y analgésicos en niños; y discutir las implicaciones de la práctica de los cuidados de enfermería brindados a niños que presentan reacciones adversas al uso de analgésicos y sedantes. Este es un estudio cualitativo. Se entrevistó a quince miembros del equipo de enfermería que trabajaban en una UCIP de un hospital especializado en enfermedades crónicas y raras, utilizando la técnica de la entrevista, la ficha de caracterización participante, el diario de campo para la observación no parficipante y la recolección de información en historias clínicas. Se apoyó el software Iramuteq y se utiliz6 análisis textual discursivo. Se encontró que las principales reacciones adversas identificadas por los profesionales de enfermería fueron irritabilidad, llanto y agitaci6n. La práctica del cuidado de enfermería se desarrolla según reacciones adversas previamente identificadas y varía dependiendo del profesional de enfermería que atiende al niño, no existiendo un estándar institucional preestablecido. Entre los cuidados descritos se encuentran: baño tibio, administración de dosis fraccionadas de sedación según prescripción médica y confort por parte del familiar responsable o por el propio profesional, sin embargo, no se observaron registros en las historias clínicas respecto a estas reacciones adversas, así como estos ínformamn cuidados. Se destaca que existe inseguridad por parte del equipo de enfermería respecto de su conocimiento sobre las reacciones adversas relacionadas al uso de sedantes y analgésicos y, como implicaciones para la práctica, la falta de identidad en su cuidado, interfiriendo en su autonomía y protagonismo profesional, siendo el médico el más activo en este tema. Se concluye que el equipo de enfermería reconoce algunos signos y síntomas de reacciones adversas en el uso de sedantes y analgésicos, sin embargo, es necesario mejorar y actualizar respecto al uso de estos medicamentos, sus reacciones adversas y los cuidados que se deben brindar para reconocer su desempeño y comprender su posición dentro del equipo multidisciplinario.

Efficacy and safety of dexmedetomidine in maintaining hemodynamic stability in pediatric cardiac surgery: a systematic review and meta-analysis

Abstract Objectives: Dexmedetomidine (DEX) is a highly selective alpha-2 adrenergic receptor agonist, which is the main sedative in the intensive care unit. This study aims to investigate the effectiveness and adverse events of DEX in maintaining hemodynamic stability in pediatric cardiac surgery. Sources: Databases such as PubMed, Cochrane, Web of Science, WANFANG STATA and China National Knowledge Infrastructure were searched for articles about the application of DEX in maintaining hemodynamic stability during and after pediatric cardiac surgery up to 18th Feb. 2021. Only randomized controlled trials were included and random-effects model meta-analysis was applied to calculate the standardized mean deviation (SMD), odds ratio (OR) and 95% confidence interval (CI). Summary of the findings: Fifteen articles were included for this meta-analysis, and 9 articles for qualitative analysis. The results showed that preoperative prophylaxis and postoperative recovery of DEX in pediatric patients undergoing cardiac surgery were effective in maintaining systolic blood pressure (SBP), mean arterial pressure (MAP), diastolic blood pressure (DBP) and reducing heart rate (HR) (SBP: SMD = -0.35,95% CI: -0.72, 0.01; MAP: SMD = -0.83, 95% CI: -1.87,0.21; DBP: SMD = -0.79,95% CI: -1.66,0.08; HR: SMD = -1.71,95% CI: -2.29, -1.13). In addition, the frequency of Junctional Ectopic Tachycardia in the DEX treatment group was lower than that in the placebo group. Conclusions: The application of DEX for preoperative prophylaxis and postoperative recovery in pediatric cardiac surgery patients are effective in maintaining hemodynamic stability, and the clinical dose of DEX is not significantly related to the occurrence of pediatric adverse events which may be related to individual differences.

Factores de riesgo de reacción paradójica asociados a sedación endovenosa con midazolam / Paradoxical reactions associated with midazolam conscious sedation

Background: Benzodiazepines are used for perioperative conscious sedation. However, its use may be associated with paradoxical reactions. The known risk factors for these reactions are age, alcohol and drug abuse and psychiatric disorders. Aim: To assess the incidence and impact of risk factors of paradoxical reactions to midazolam. Material and Methods: Cross sectional study of 218 patients aged 50 ± 16 years (51% women) scheduled for elective surgical procedures under regional anesthesia and midazolam sedation. The paradoxical reactions were classified according to their severity in three categories. Results: The incidence of paradoxical reactions to midazolam was 8.3% (95% confidence interval (CI) 5.0-12.7). All were mild and only 28% of the affected patients required pharmacological treatment, none of them flumazenil. A multivariable logistic regression model showed that the variables independently associated with a paradoxical reaction to midazolam were the use of psychoactive medications (Odds Ratio (OR) = 3.4 [1.1-11], p = 0.04, and the dose of midazolam (OR 1.35 [1.03-1.78], p = 0.03. Conclusions: The incidence of paradoxical reactions to midazolam was 8,3% and all were mild. Their risk factors are the use of psychoactive medications and the use of higher doses of midazolam.

Causative drugs for drug-induced cutaneous reactions in central China: a 608-case analysis

Abstract Background: Reports regarding the causative drugs of drug-induced cutaneous adverse reactions in China are indistinct, such that different regions have reported the spectrum of drugs differs substantially in different clinical conditions. Objective: To explore the causative drugs that led to cutaneous reactions. Methods: Adverse drug reaction reports from central China were collected and divided into cutaneous adverse reactions and severe cutaneous adverse reactions groups. Cases were reviewed retrospectively for causative drugs. Results: The male:female ratio was equal in both cutaneous adverse reactions and severe cutaneous adverse reactions. In cutaneous adverse reactions (n = 482), the highest incidence happened between 51 and 60 years of age and the top three causative drugs were antibiotics (48%), Chinese medicine (16%), and allopurinol (9%). In severe cutaneous adverse reactions (n = 126), the highest incidence happened between 41 and 50 years of age and the top three causative drugs were sedative-hypnotics and antiepileptics (39%), antibiotics (22%), and allopurinol (15%). Carbamazepine was the most frequently used single-drug (16/18) in sedative-hypnotics and antiepileptics. β-lactams were the most frequently used antibiotics that induced both cutaneous adverse reactions and severe cutaneous adverse reactions. Study limitations: The small sample size, retrospective design, collection of cutaneous adverse reactions and severe cutaneous adverse reactions at different time frames and locations, and exclusion of patients taking more than five medications are limitations of the study. Conclusions: Gender does not affect cutaneous adverse reactions and severe cutaneous adverse reactions. The top three drugs to induce cutaneous adverse reactions are antibiotics, Chinese medicine, and allopurinol, while those that triggered severe cutaneous adverse reactions are sedative-hypnotics and antiepileptics, antibiotics, and allopurinol. Carbamazepine is the most frequent single drug that induces severe cutaneous adverse reactions. β-lactams are the most frequently used antibiotics that induce both cutaneous adverse reactions and severe cutaneous adverse reactions.

Eventos adversos durante transporte intra-hospitalar de pacientes críticos em hospital de grande porte / Adverse events during intrahospital transport of critically ill patients in a large hospital

RESUMO Objetivo: Descrever a incidência de eventos clínicos e não clínicos durante o transporte intra-hospitalar de pacientes críticos e analisar os fatores de risco associados. Métodos: Estudo de coorte, com coleta retrospectiva, no período de outubro de 2016 a outubro de 2017, tendo sido analisados todos os transportes intra-hospitalares para fins diagnósticos e terapêuticos em hospital de grande porte, que contava com seis unidades de terapia intensiva adulto, sendo avaliados os eventos adversos e os fatores de risco relacionados. Resultados: No período, foram realizados 1.559 transportes intra-hospitalares, em 1.348 pacientes, com média de idade de 66 ± 17 anos, tempo médio de transporte de 43 ± 34 minutos. Durante o transporte, 19,8% dos pacientes estavam em uso de drogas vasoativas; 13,7% em uso de sedativos e 10,6% estavam sob ventilação mecânica. Eventos clínicos ocorreram em 117 transportes (7,5%) e não clínicos em 125 transportes (8,0%). Falhas de comunicação foram prevalentes, no entanto, aplicando-se análise multivariada, uso de sedativos, noradrenalina e nitroprussiato, e o tempo de transporte maior que 36,5 minutos estiveram associados a eventos adversos clínicos. Uso de dobutamina e tempo de transporte superior a 36,5 minutos estiveram associados a eventos não clínicos. Ao final do transporte, 98,1% dos pacientes apresentaram condições clínicas inalteradas em relação ao seu estado basal. Conclusão: Transportes intra-hospitalares estão relacionados à alta incidência de eventos adversos; o tempo de transporte e a utilização de sedativos e drogas vasoativas estiveram relacionados a esses eventos.

ABSTRACT Objective: To describe the incidence of clinical and non-clinical events during intrahospital transport of critically ill patients and to analyze the associated risk factors. Methods: Cohort study with retrospective data collected from October 2016 to October 2017. All cases of intrahospital transport for diagnostic and therapeutic purposes in a large hospital with six adult intensive care units were analyzed, and the adverse events and related risk factors were evaluated. Results: During the study period, 1,559 intrahospital transports were performed with 1,348 patients, with a mean age of 66 ± 17 years and a mean transport time of 43 ± 34 minutes. During transport, 19.8% of the patients were using vasoactive drugs; 13.7% were under sedation; and 10.6% were under mechanical ventilation. Clinical events occurred in 117 transports (7.5%), and non-clinical events occurred in 125 (8.0%) transports. Communication failures were prevalent; however, the multivariate analysis showed that the use of sedatives, noradrenaline and nitroprusside and a transport time greater than 36.5 minutes were associated with adverse clinical events. The use of dobutamine and a transport time greater than 36.5 minutes were associated with non-clinical events. At the end of transport, 98.1% of the patients presented unchanged clinical conditions compared with baseline. Conclusion: Intrahospital transport is related to a high incidence of adverse events, and transport time and the use of sedatives and vasoactive drugs were related to these events.

Síndrome de infusión por propofol en el adulto / Propofol infusion syndrome

Propofol infusion syndrome is a rare but lethal complication of propofol administration. The most common clinical presentation is high anion-gap metabolic acidosis, heart failure, rhabdomyolysis and hyperkalemia in patients receiving a prolonged propofol infusion. It has an estimated incidence of 1,1% in patients receiving propofol and its mortality varies between 18 and 81%. The most important risk factor is an infusion over 4 mg/kg/h of propofol and a critically sick patient. Management of a diagnosed PRIS is based on immediate discontinuation of propofol and support therapy.

El síndrome de infusión de propofol es una complicación rara, pero posiblemente letal de la administración de propofol (Propofol Infusion Syndrome, PRIS) Generalmente, se presenta como una acidosis metabólica con anion Gap aumentado, falla cardiaca rápidamente progresiva, rabdomiólisis e hiperkalemia, junto con el antecedente claro de una infusión prolongada de la droga. La incidencia se estima en un 1,1% en los pacientes que reciben propofol y su mortalidad varía entre el 18 al 81%. Los factores de riesgo son: una infusión de propofol mayor a 4 mg/kg/h y pacientes críticos. El tratamiento se basa en la suspensión de la droga y medidas de soporte hemodinámico.

Actualización en enfermedad con cuerpos de Lewy / Update in Lewy body disease

La enfermedad con cuerpos de Lewy incluye 2 entidades que podrían ser consideradas variantes clínicas de una misma patología: la demencia con cuerpos de Lewy y la demencia en enfermedad de Parkinson. Con la finalidad de describir correctamente lo que sucede en la evolución de la enfermedad se divide el cuadro en etapa prodrómica y de demencia propiamente dicha. La primera está clínicamente representada por aquel período en el cual, si bien el paciente exhibe algunos signos y síntomas propios de la enfermedad, no reúne criterios de demencia. A pesar de ser difícil de definir y por carecerse todavía de contundentes datos clínicos y biomarcadores, se caracteriza principalmente por deterioro leve selectivo en función atencional ­ visuoespacial, trastorno del sueño REM y disautonomía‒. La segunda etapa está claramente caracterizada en los criterios de consenso del año 2005. Recientemente hemos publicado la validación de un instrumento llamado ALBA Screening Instrument, que permite diagnosticar con alta sensibilidad y especificidad la enfermedad aun en etapas tempranas y diferenciarla de otras patologías semejantes. La tomografía por emisión de positrones (PET) para transportador de dopamina es el procedimiento de referencia (gold standard) del diagnóstico. El tratamiento sintomático con anticolinesterásicos y neurolépticos atípicos favorece una buena evolución de la enfermedad y es fundamental tener en cuenta evitar medicamentos que pueden dañar gravemente a los pacientes como los anticolinérgicos y antipsicóticos típicos. Los avances en el diagnóstico y la difusión del impacto de esta enfermedad en la población contribuirán a generar mayores esfuerzos de investigación para hallar un tratamiento eficaz, preventivo o curativo o de ambas características.

Lewy body disease includes 2 entities that could be considered clinical variants of the same pathology: Dementia with Lewy bodies and Parkinson's disease Dementia. Two stages of the disease are described in this review, a prodromal stage and one of explicit dementia. The first one is clinically represented by that period in which, the patient exhibits some typical features of the disease, but not dementia criteria. Despite being difficult to define the prodromal stage and that strong clinical data and biomarkers are still lacking, there is evidence to characterize it mainly by mild selective impairment in attention and visuo-spatial function, REM sleep disorder and dysautonomia. The second stage is clearly characterized in the known consensus criteria of 2005. We have recently published the validation of an instrument called ALBA Screening Instrument which showed a high sensitivity and specificity for diagnosis of the disease even in the early stages. It´s useful to differentiate the disease from other similar pathologies. Positron Emission Tomography for dopamine transporter is the gold standard of diagnosis in life. Symptomatic treatment with anticholinesterases and atypical neuroleptics help patients in their evolution of the disease. Anticholinergics and typical antipsychotics are agents to avoid in the treatmen of the disease because can severely damage patients. Future advances in the diagnosis and dissemination of the knowledge of the disease will contribute to generate greater research efforts to find an effective preventive and / or curative treatment.

The correlation among the Ramsay sedation scale, Richmond agitation sedation scale and Riker sedation agitation scale during midazolam-remifentanil sedation / Correlação entre a escala de sedação de Ramsay, escala de sedação-agitação de Richmond e escala de sedação-agitação de Riker durante sedação com midazolam-remifentanil

Abstract Background and objectives: Sedative and analgesic treatment administered to critically ill patients need to be regularly assessed to ensure that previously stated goals are well achieved as the risk of complications of oversedation is minimized. We revised and prospectively tested the Ramsay Sedation scale (RSS) for interrater reliability and compared it with the Sedation-Agitation Scale (SAS) and the Richmond Agitation Sedation Scale (RASS) to test construct validity during midazolam-remifentanil sedation. Methods: A convenience sample of ICU patients was simultaneously and independently examined by pairs of trained evaluators by using the revised SAS, RSS, and RASS. Ninety-two ICU patients were examined a total of 276 times by evaluator pairs. Results: The mean patient age was 61.32 ± 18.68 years, 45,7% were female (n = 42), 54.3% male (n = 50). Their APACHE values varied between 3 and 39 with an average of 13.27 ± 7.86 and 75% of the cases were under mechanical ventilation. When classified by using RSS (2.70 ± 1.28), 10.9% were anxious or agitated (RSS1), 68.5% were calm (RSS 2-3), and 20.6% were sedated (RSS 4-6). When classified by using RASS (-0.64 ± 1.58), 20.7% were anxious or agitated (RASS+1 to +4), 63.0% were calm (RASS 0 to -2), and 16.3% were sedated (RASS -3 to -5). When classified by using SAS (2.63 ± 1.00), 12% were anxious or agitated (SAS 5-7), 57.6% were calm (SAS 4), and 30.4% were sedated (SAS 1-3). RSS was correlated with the SAS (r = -0.656, p < 0.001) and RASS was correlated with the SAS (r = 0.565, p < 0.001). RSS was highly correlated with the RASS (r = -0.664, p < 0.001). Conclusions: Ramsay is both reliable and valid (high correlation with the RASS and SAS scales) in assessing agitation and sedation in adult ICU patients.

Resumo Justificativa e objetivos: O tratamento de pacientes em estado crítico com sedativos e analgésicos deve ser regularmente avaliado para garantir que as metas pré-definidas sejam atingidas, bem como minimizar o risco de complicações resultantes de sedação em excesso. Conduzimos uma revisão e testamos prospectivamente a Escala de Sedação de Ramsay (Ramsay Sedation Scale [RSS]) para a confiabilidade interavaliador e a comparamos com a Escala de Sedação e Agitação de Riker (Riker Sedation-Agitation Scale [RRSAS]) e a Escala de Sedação e Agitação de Richmond (Richmond Agitation Sedation Scale [RASS]) para testar a validade de construto durante a sedação com midazolam-remifentanil. Métodos: Uma amostra de conveniência de pacientes de UTI foi simultânea e independentemente examinada por pares de avaliadores treinados com o uso das escalas revisadas RRSAS, RSS e RASS. Foram examinados 92 pacientes de UTI por pares de avaliadores em 276 momentos. Resultados: A média dos pacientes foi de 61,32 ± 18,68 anos; 45,7% eram do sexo feminino (n = 42) e 54,3% do masculino (n = 50). Seus escores APACHE variaram entre 3-39, com média de 13,27 ± 7,86, e 75% dos casos receberam ventilação mecânica. Quando RSS foi usada para a classificação (2,70 ± 1,28), 10,9% dos pacientes estavam ansiosos ou agitados (RSS1), 68,5% estavam calmos (RSS 2 a 3) e 20,6% estavam sedados (RSS 4 a 6). Quando RASS foi usada para a classificação (-0,64 ± 1,58), 20,7% dos pacientes estavam ansiosos ou agitados (RASS +1 a +4), 63,0% estavam calmos (RASS 0 a -2) e 16,3% estavam sedados (RASS -3 a -5). Quando RSAS foi usada para a classificação (2,63 ± 1,00), 12% dos pacientes estavam ansiosos ou agitados (RSAS 5 a 7), 57,6% estavam calmos (RSAS 4) e 30,4% estavam sedados (RSAS 1 a 3). Houve correlação de RSS com RSAS (r = -0,656, p < 0,001) e de RASS com RSAS (r = 0,565, p < 0,001). Houve forte correlação de RSS com RASS (r = -0,664, p < 0,001). Conclusões: A RSS é confiável e válida (forte correlação com RASS e RSAS) para avaliar a sedação e agitação em pacientes adultos internados em UTI.

Safety degree assessment of drugs used in conscious sedation for colonoscopy in patients that develop respiratory depression / Avaliação do grau de segurança dos fármacos utilizados na sedação superficial na colonoscopia em pacientes que desencadeiam depressão respiratória

ABSTRACT Objective: To analyze the safety degree of drugs used in colonoscopy during conscious sedation in patients developing respiratory depression. Methods: Cross-sectional observational study that evaluated 1120 patients who underwent colonoscopy between February 2015 and February 2016. Physical characteristics, surgical history and previous colonoscopies, indication and conditions of the current examination, fentanyl and midazolam doses and subsequent complications were analyzed. Level of significance: p < 0.05. Chi-square test was used for association of categorical variables, whereas Student's t test was used to compare means and Spearman's coefficient for correlation. Results: There were 661 female (59%) and 459 (41%) male patients, with a mean age of 54.90 (20-87) years and BMI of 27.00 (14.5-45.4). Of the 1120 patients, only 2 (0.2%) had respiratory depression, reversed with lanexat. Patients who had complications were of both genders, with a body mass index of 21.25 and 28.7. There was a correlation between the required dose of fentanyl and age (p < 0.001 to −0.121 Spearman's coefficient), as well as midazolam (p < 0.001 - Spearman's coefficient −0.452) and increasing age was associated with a lower dose of the drug. Conclusion: The number of patients with complications was 0.17%. The age of the patient showed an inverse association, i.e., the older the patient, the lower the required dose of medication. The drugs used in colonoscopy show a high degree of safety, corroborating their frequent use for superficial/conscious sedation in this procedure.

RESUMO Objetivo: Analisar o grau de segurança dos fármacos utilizados na colonoscopia sob sedação superficial em pacientes que desencadeiam depressão respiratória. Métodos: Estudo observacional transversal, que avaliou 1.120 pacientes que realizaram colonoscopia entre Fevereiro de 2015 e Fevereiro de 2016. Analisaram-se características físicas, histórico cirúrgico e colonoscopias prévias, indicação e condições do exame atual, dose de fentanil e midazolam e complicações apresentadas. Nível de significância adotado: p < 0,05. Utilizou-se teste Qui-quadrado para associação de variáveis categóricas, teste t de Student para comparação de médias e coeficiente de Spearman para correlação. Resultados: Foram 661 pacientes do sexo feminino (59%) e 459 (41%) do sexo masculino, com média de idade de 54,90 (20-87) anos e IMC de 27,00 (14,5-45,4). Dos 1120 pacientes, apenas 2 (0,2%) exibiram depressão respiratória revertida com lanexate. Os pacientes que apresentaram complicação eram de sexos diferentes, com índices de massa corpórea de 21,25 e 28,7. Houve correlação entre a dose necessária de fentanil e a idade (p < 0,001 - coef Spearmann - 0.121), assim como a de midazolam (p < 0,001 - coef Spearmann - 0.452), sendo que com o aumento da idade se correlacionou com uma menor dose utilizada de medicamento. Conclusão: O número de pacientes que apresentaram alguma complicação foi 0,17%. A idade do paciente tem associação inversa, quanto maior a idade do paciente, menor é a dose necessária de medicamentos. Verifica-se alto grau de segurança dos medicamentos utilizados na colonoscopia, corroborando sua utilização frequente para a sedação superficial/consciente neste procedimento.

Incidencia del síndrome de abstinencia en niños críticamente enfermos / Incidence of withdrawal syndrome in critically ill children

Objetivo: determinar la incidencia del síndrome de abstinencia (SA), describir presentación clínica e identificar la presencia de factores de riesgo. Metodología: se realizó un estudio prospectivo, observacional, de evaluaciones reiteradas usando la Sophia Observation Withdrawal Symptoms Scale (SOWS), en la Unidad de Cuidado Intensivo de Niños (UCIN) de 20 camas, del Centro Hospitalario Pereira Rossell (CHPR). Se incluyeron los niños ingresados en UCIN entre el 1 de noviembre de 2013 y el 30 de setiembre de 2014 tratados con benzodiacepinas y/o opiáceos por cinco días o más. Se registró: duración de la estadía, fármacos utilizados para sedación y analgesia, días de uso, máximo de dosis, dosis total acumulada. El diagnóstico de SA se realizó a través del uso de la SOWS. Los pacientes fueron divididos en dos grupos, con y sin SA. Se analizaron y compararon las características de ambos grupos. Resultados: se incluyeron 39 niños. La incidencia de SA fue 18% (7/39). Los ítems del SOWS más frecuentes fueron ansiedad y sueño menor a 1 hora. Los niños que desarrollaron SA presentaron dosis acumulativas más elevadas tanto de midazolam (54,1 mg/kg vs 44,2 mg/kg) como de fentanilo (464,2 mg/kg vs 380,1 mg/kg). Conclusiones: el SA fue frecuente en este grupo de niños. Las dosis acumulativas fueron mayores en el grupo con SA. La SOWS es una herramienta útil y de fácil aplicación para el diagnóstico de SA.

Objective: The study aims to determine the incidence of withdrawal syndrome, its clinical features and the presence of risk factors. Methodology: An observational and prospective study. Assessment was repeated and the Sophia Observation Withdrawal Symptoms Scale (SOWS) was used. The study was conducted at the Pediatric Intensive Care Unit (PICU) of Centro Hospitalario Pereira Rossell (CHPR). Hospitalized children in PICU between 1/11/2013- 30/9/2014 and treated with benzodiazepines and opioids during 5 days or more were included in the study. Days of stay at the PICU, agents used for sedation (dose, duration) and cumulative doses were recorded. Withdrawal syndrome diagnosis was done using the SOWS. Results: 39 children were included in the study. The incidence of withdrawal syndrome was 18% (7/39). Children who developed withdrawal syndrome presented higher cumulative doses of midazolam (54.1 mg/kg vs. 44.2 mg/kg) and fentanyl (464.2µg/kg vs. 380.1 µg/kg) than those without withdrawal syndrome. Conclusions: the withdrawal syndrome was frequent in this population. Cumulative doses of midazolam and fentanyl were higher in those with withdrawal symptoms. The SOWS is a useful resource for diagnosis.

Sedation with dexmedetomidine for conducting electroencephalogram in a patient with Angelman syndrome: a case report / Sedação com dexmedetomidina para realização de eletroencefalograma em paciente portadora de síndrome de Angelmann: relato de caso

ABSTRACT INTRODUCTION: Angelman syndrome is characterized by severe mental retardation and speech and seizure disorders. This rare genetic condition is associated with changes in GABAA receptor. Patients with Angelman syndrome need to be sedated during an electroencephalogram ordered for diagnostic purposes or evolutionary control. Dexmedetomidine, whose action is independent of GABA receptor, promotes a sleep similar to physiological sleep and can facilitate the performing of this examination in patients with Angelman syndrome. CASE REPORT: Female patient, 14 years old, with Angelman syndrome; electroencephalogram done under sedation with dexmedetomidine. The procedure was uneventful and bradycardia or respiratory depression was not recorded. The examination was successfully interpreted and epileptiform activity was not observed. CONCLUSION: Dexmedetomidine promoted satisfactory sedation, was well tolerated and enabled the interpretation of the electroencephalogram in a patient with Angelman syndrome and seizure disorder.

RESUMO INTRODUÇÃO: a síndrome de Angelman (SA) é caracterizada por retardo mental grave, distúrbio da fala e desordem convulsiva. Essa condição genética rara está associada a alterações do receptor GABA-A. Pacientes portadores de SA necessitam ser sedados durante a feitura de eletroencefalograma (EEG), indicado para fins diagnósticos ou controle evolutivo. A dexmedetomidina, cuja ação independe do receptor GABA, promove sono semelhante ao fisiológico e pode viabilizar a feitura desse exame em pacientes com SA. RELATO DE CASO: paciente feminina, 14 anos, portadora de SA, fez EEG sob sedação com dexmedetomidina. O procedimento transcorreu sem intercorrências e não foi registrada bradicardia ou depressão respiratória. O exame foi interpretado com sucesso e atividade epileptiforme não foi observada. CONCLUSÃO: a dexmedetomidina promoveu sedação satisfatória, foi bem tolerada e possibilitou a interpretação do EEG em paciente com SA e desordem convulsiva.

Complicaciones cardiopulmonares asociadas a propofol versus sedación tradicional para procedimientos endoscópicos digestivos en adultos: revisión sistemática y metaanálisis de estudios clínicos randomizados (ECR) / Cardiopulmonary complications associated with traditional versus propofol sedation for gastrointestinal endoscopic procedures in adults: systematic review and metaanalysis of randomized clinical trials (RCT)

Abstract Background: For sedation in endoscopy, propofol offers advantages for its fast recovery profile compared with traditional sedation (opioids and/or benzodiazepines). However, their use may be associated with deeper levels of sedation, increasing the risk of complications. Aims: To evalúate the safety of propofol compared with traditional endoscopic procedures. To analyze influence of operator sedation in endoscopic procedures. Materials and Methods: ECR comparing cardiopulmonary complications (hypoxia, hypotension, bradycardia) between propofol and traditional sedation in adults undergoing endoscopy, were included. Wesearched MEDLINE, EMBASE, Cochrane Controlled Trials Registry, LILACS. Relative risk (RR) was calculated. The data were analyzed using Rev Man v.5.3 (The Cochrane Collaboration). Results: 8 ECR were selected, totaling 739 patients; of these, 381 received propofol and 358 traditional sedation. An anesthesiologistadministered sedation in 3 of the 8 papers, in patients with greater comorbidity and deeper level of sedation.Compared with traditional sedation, the RR of developing hypoxia, hypotension or bradycardia with propofolwas 0.78 (95% CI, 0.56-1.08), 1.37 (95% CI, 0.82-2.28), 0.57 (95% CI, 0.27-1.24) respectively. The RR of hypoxia in using propofol by an anesthesiologist was 1.59 (95% CI, 0.38-6.72) and non-anesthesiologist was0.75 (95% CI, 0.53-1.05). No statistically significant differences between propofol and traditional sedation for the analyzed adverse effects were found. Conclusions: Use of propofol compared with traditional sedation forendoscopic procedures do not increase the risk of cardiopulmonary complications. There were no significant differences when analyzing the professional in charge of sedation.

Resumen Introducción: Para sedación en endoscopia, el propofol ofrece ventajas por su rápido perfil de recuperación comparado con sedación tradicional (opiodes y/o benzodiacepinas). Sin embargo, su uso podría estar asociado a niveles de sedación más profunda, aumentando el riesgo de complicaciones. Objetivos: Evaluarla seguridad del propofol comparado con sedación tradicional para procedimientos endoscópicos. Analizar la influencia del operador de la sedación en procedimientos endoscópicos. Materiales y Métodos: Se incluyeron ECR que compararan complicaciones cardiopulmonares (hipoxia, hipotensión, bradicardia) entre propofol y sedación tradicional, en adultos sometidos a endoscopia. Se buscó en: MEDLINE, EMBASE, Cochrane Controlled Trials Registry, LILACS. Se calculó riesgo relativo (RR). Los datos se analizaron con RevManv.5.3 (The Cochrane Collaboration). resultados: 8 ECR fueron seleccionados, sumando 739 pacientes; de ellos, 381 recibieron propofol y 358 sedación tradicional. Un anestesiólogo administró la sedación en 3 de los8 trabajos, en pacientes con mayor comorbilidad y nivel de sedación más profunda. Comparado con sedación tradicional, el RR de desarrollar hipoxia, hipotensión o bradicardia con propofol fue de 0,78 (IC 95%, 0,561,08), 1,37 (IC 95%, 0,82-2,28), 0,57 (IC 95%, 0,27-1,24) respectivamente. El RR de hipoxia al usar propofolpor anestesiólogo fue de 1,59 (IC 95%, 0,38-6,72) y por no-anestesiólogo fue de 0,75 (IC 95%, 0,53-1,05).No se encontraron diferencias estadísticamente significativas entre propofol y sedación tradicional para los efectos adversos analizados. conclusiones: El uso de propofol comparado con sedación tradicional para procedimientos endoscópicos no aumenta el riesgo de complicaciones cardiopulmonares. No hubo diferencias significativas al analizar el profesional a cargo de la sedación.

Eszopiclone versus zopiclone in the treatment of insomnia

OBJECTIVE: To determine the therapeutic effects of two selective GABA-A agonists, zopiclone and eszopiclone, in the treatment of insomnia. METHODS: This study comprised a phase III, single-center, randomized, double-blind, double-dummy, parallel-group, non-inferiority trial. Patients were randomized to receive zopiclone 7.5 mg or eszopiclone 3 mg, both orally, for four weeks. In total, 199 patients were evaluated during two visits and then followed for at least six weeks. The primary endpoint was the Insomnia Severity Index after four weeks of treatment. Secondary endpoints were obtained through polysomnography data, including total sleep time, sleep latency and sleep efficiency. The frequency of adverse events was also analyzed. ClinicalTrials.gov: NCT01100164. RESULTS: The primary efficacy analysis demonstrated the non-inferiority of eszopiclone over zopiclone. Analysis of objective parameters assessed by polysomnography showed that eszopiclone increased total sleep time and also improved sleep efficiency. The safety profile of both study treatments was similar and the most common events reported in both groups were dysgeusia, headache, dizziness, irritability and nausea. Adverse events were observed in 223 patients, 109 (85.2%) in the eszopiclone group and 114 (87.7%) in the zopiclone group. CONCLUSION: Based on the Insomnia Severity Index at the end of four weeks of treatment, eszopiclone demonstrated efficacy comparable to that of zopiclone in the treatment of insomnia, increasing total sleep time as well as sleep efficiency according to polysomnography.

Effects of Dexmedetomidine Infusion on the Recovery Profiles of Patients Undergoing Transurethral Resection

Transurethral resection has been the gold standard in the operative management of benign prostatic hyperplasia and bladder tumor; however, it is associated with several complications that may cause patient discomfort. We evaluated the usefulness of continuous infusion of dexmedetomidine on emergence agitation, hemodynamic status, and recovery profiles in patients undergoing elective surgery by a randomized clinical trial. Sixty patients aged 30 to 80 yr who were scheduled for elective transurethral resection under general anesthesia were included in this study. Participants were randomly assigned to two groups (control group, group C; dexmedetomidine group, group D). A total of 60 male patients were enrolled in this study and randomly assigned to group C (n=30) or group D (n=30). The quality of emergence in group D was marked by a significantly lower incidence of emergence agitation than in group C (P=0.015). Patients in group D therefore felt less discomfort induced by the indwelling Foley catheter than those in group C (P=0.022). No statistically significant differences were found between the two groups with respect to side effects including bradycardia (P=0.085), hypotension (P=0.640), and postoperative nausea and vomiting (P=0.389). Our study showed that intraoperative dexmedetomidine infusion effectively reduced the incidence and intensity of emergence agitation and catheter-induced bladder discomfort without delaying recovery time and discharge time, thus providing smooth emergence during the recovery period in patients undergoing transurethral resection (Clinical Trial Registry No. KT0001683).

Safety of Gastroenterologist-Guided Sedation with Propofol for Upper Gastrointestinal Therapeutic Endoscopy in Elderly Patients Compared with Younger Patients

BACKGROUND/AIMS: Propofol sedation for elderly patients during time-consuming endoscopic procedures is controversial. Therefore, we investigated the safety of using propofol in elderly patients during upper gastrointestinal therapeutic endoscopy. METHODS: The medical records of 160 patients who underwent therapeutic endoscopic procedures under gastroenterologist-guided propofol sedation at a single institution were retrospectively reviewed. The subjects were divided into two groups: a younger group, patients or =75 years old. The two groups were compared with respect to the therapeutic regimen, circulatory dynamics, and presence/absence of discontinuation of propofol treatment. RESULTS: Although the number of patients with liver dysfunction was higher in the elderly group, there were no other significant differences in the baseline characteristics, including the American Society of Anesthesiologists classification, between the elderly and younger groups. The average maintenance rate of continuous propofol infusion was lower in the elderly patients. No statistically significant differences were found in the occurrence of adverse events between the elderly and younger groups. None of the patients returned to a resedated state after the initial recovery from sedation. CONCLUSIONS: Gastroenterologist-guided propofol sedation in elderly patients can be safely achieved in the same manner as that in younger patients, even for time-consuming upper gastrointestinal therapeutic endoscopic procedures.
