Incidence and outcomes of ventilator associated pneumonia in pediatric patients: an observational study

Background: Ventilator associated pneumonia (VAP) is very common in pediatric intensive care unit (PICU) intubated patients and also responsible for major morbidity and mortality. Usually, it develops after 48 hours of mechanically ventilated patients, its incidence increases as the duration of time increases and it is a major risk factor for VAP. The present study was carried out to know the overall incidence of VAP in mechanically ventilated patients in PICU.Methods: The study was carried out in PICU of the department of pediatrics, B. R. D. Medical College, Gorakhpur from October 2020 to October 2021. Patients aged between 1 year to 15 years were included in the study.Results: There were 50 (59.5%) patients� male and 34 (40.5%) patients� female under investigation. The clinical pulmonary infection score (CPIS) values ranged from the mean value of 4.38�30 at 36th hours to 7.33�92 at 96th hours of intubation. VAP was present in 23 (27.3%) patients while 62 (73.8%) patients were having no VAP. Among VAP associated patients, 14.3% were Acinetobacter positive, 5.95% were Klebsiella positive and 3.57% were E. coli positive.Conclusions: Parameters of CPIS associated with VAP revealed that Acinetobactor was comparative more common organism and the age group of 1 to 5 years was more sensitive. VAP can be reduced by decreasing the duration of mechanical ventilation.

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.

The Role of the Dental Surgeon in the Pediatric Intensive Care Unit / O Papel do Cirurgião-Dentista na Unidade de Terapia Intensiva Pediátrica

Dentistry plays a significant role in the supportive care of hospitalized children in Pediatric Intensive Care Units (PICUs) as these patients arrive in this environment with altered immune systems and compromised oral health. This paper aims to present an integrative literature review on the role of dentists in the hospital setting, particularly in the PICU, and discuss the challenges encountered in this environment. A free search was conducted on the electronic platforms PubMed, Scientific Electronic Library Online (SciELO), Latin American and Caribbean Literature in Sciences (Lilacs), and Virtual Health Library (BVS) from January to February 2023, with no defined publication period and including all types of studies. Health Science descriptors (DeCS/MeSH) were used in English and Portuguese, applying Boolean operators. According to the data collected, among the conditions requiring admission to the PICU, respiratory disorders, heart and kidney failure, neurological disorders, severe metabolic diseases, infections, injuries, traumas, near-drowning incidents, and post-operative care after complex surgeries stand out. Dental care in this environment reduce hospitalization time, costs, and improve the quality of life of pediatric patients. However, the integration of these professionals into the PICU is still limited. Dentists in the hospital setting optimize multidisciplinary work through protocol-based measures derived from studies conducted in adult patients in intensive care units. Due to the lack of robust evidence related to oral care practices in pediatric intensive care settings, further research is mandatory. (AU)

A Odontologia tem um papel importante na assistência de crianças hospitalizadas nas Unidades de Terapia Intensiva Pediátricas (UTIP), pois esses pacientes chegam neste ambiente com o sistema imunológico alterado e a saúde bucal comprometida. Apresentar uma revisão integrativa da literatura sobre o papel do cirurgião-dentista no hospital, em especial, na UTIP, além de discutir os desafios encontrados nesse ambiente. Uma busca foi conduzida nas plataformas eletrônicas PubMed, Scientific Eletronic Library Online (SciElo), Latin American and Caribbean Literature in Sciences (Lilacs) e Biblioteca Virtual da Saúde (BVS), entre janeiro a fevereiro/2023, sem período definido de publicação e sob a inclusão de todos os tipos de estudos. Os descritores em Ciências da saúde (DeCS/MeSH) foram utilizados em inglês e português, sob aplicação dos operadoress booleanos. Segundo dados coletados, dentre as condições que necessitam de internação na UTIP, destaca-se as alterações respiratórias, insuficiência cardíaca e renal, alterações do sistema nervoso, doenças metabólicas graves, infecções, ferimentos, traumatismos, quase afogamentos e pós-operatório de cirurgias complexas. O cirurgião-dentista neste ambiente reduz o tempo de internação, os custos e aumenta a qualidade de vida dos pacientes pediátricos. Todavia, ainda é escassa a inserção deste profissional em UTIP. O cirurgião-dentista em ambiente hospitalar otimiza o trabalho multidisciplinar através de medidas baseadas em protocolos obtidos a partir de estudos em pacientes adultos em unidades de terapia intensivas. Devido a falta de evidências robustas relacionadas à prática de cuidados bucais no ambiente de cuidados intensivos pediátricos, a realização de pesquisas futuras torna-se mandatória. (AU)

Correlation between dynamic high-density lipoprotein trajectories and clinical outcomes in critically ill children / 中华实用儿科临床杂志

Objective:To characterize the longitudinal and dynamic high-density lipoprotein (HDL) trajectories in critically ill children and explore their correlation with clinical outcomes.Methods:Retrospective cohort study.All critically ill children admitted to the Pediatric Intensive Care Unit (PICU) of West China Hospital, Sichuan University from January 1, 2015 to October 1, 2020 were included in this retrospective study.Group-based trajectory modeling (GBTM) was applied to characterize the HDL trajectories in days 0-6 post-PICU admission and develop HDL trajectory groups.The in-hospital mortality rate was reported as frequency (%) and then compared by the Chi-square test or Fisher′s exact test between HDL trajectory groups.The length of stay (LOS) in the PICU was described by M( Q1, Q3), and its difference between HDL trajectory groups was evaluated by the Kruskal Wallis test.Logistic regression and multiple linear regression were used to determine the correlation between HDL trajectories and clinical outcomes.The primary outcome was in-hospital mortality rate, and the secondary outcome was LOS in the PICU. Results:A total of 4 384 critically ill children were ultimately enrolled in the study, and 6 HDL trajectory groups were developed based on GBTM analyses: group 1 (758 cases), the lowest HDL group; group 2 (1 413 cases), the low HDL group; group 3 (74 cases), the low-to-high HDL group; group 4 (621 cases), the medium HDL group; group 5 (1 371 cases), the high HDL group; and group 6 (147 cases), the highest HDL group.Logistic regression analysis showed that compared with critically ill children in group 1, those belonging to groups 2, 3, 4, 5, and 6 were at lower risks of in-hospital mortality with odds ratio ( OR): 0.475, 95%confidence interval ( CI): 0.352-0.641, P<0.001; OR: 0.093, 95% CI: 0.013-0.679, P=0.019; OR: 0.322, 95% CI: 0.208-0.479, P<0.001; OR: 0.263, 95% CI: 0.185-0.374, P<0.001, and OR: 0.142, 95% CI: 0.044-0.454, P=0.001, respectively.Multiple linear regression analysis revealed that compared with critically ill children in group 1, those belonging to groups 4, 5, and 6 had the trend of shorter LOS in PICU, and the β value and 95% CI were β: -4.332, 95% CI: -5.238- -3.426, P<0.001; β: -3.053, 95% CI: -3.809--2.297, P<0.001; β: -6.281, 95% CI: -7.842--4.721, P<0.001, respectively. Conclusions:The dynamic HDL trajectories during 0-6 days after PICU admission are associated with in-hospital mortality rate of critically ill children.The HDL trajectory at a persistently low level is associated with higher mortality, while the HDL trajectory at a persistently high level or with the trend from a low level rising to a high level shows a lower risk of mortality.It is suggested that the HDL trajectory model may become an indicator to predict the condition and prognosis of critically ill children.

Analysis of the distribution characteristics and antibiotic resistance of pathogen in children with hematological disorders and cancers complicated with sepsis in PICU / 中国小儿急救医学

Objective:To explore the distribution characteristics and antibiotic resistance of pathogen in children with hematological disorders and cancers complicated with sepsis in pediatric intensive care unit (PICU).Methods:The clinical data of children with hematological disorders and cancers complicated with sepsis hospitalized at Shenzhen Children′s Hospital affiliated to China Medical University from January 2016 to August 2023 were retrospectively analyzed. Patients were divided into survival group and death group based on the outcome of sepsis on 28 days after diagnosis.Results:A total of 202 sepsis episodes occurred in 176 children were enrolled in this study. Among all, 144 (71.3%) cases of bloodstream infection, 59 (29.2%) cases of pulmonary infection, 21 (10.4%) cases of abdominal infection, 9 (4.5%) cases of soft tissue infection, 9 (4.5%) cases of nervous system infection, and 3 (1.5%) cases of urinary tract infection. A total of 244 pathogenic strains were identified, in which 74 (30.3%) cases were gram-positive bacteria. The top 3 pathogens isolated were Coagulase negative Staphylococcus (21 strains), Staphylococcus aureus (19 strains) and Streptococcus pneumoniae (13 strains). Gram-negative bacteria accounted for 122 (50.0%) strains, in which top 3 were Klebsiella pneumonia (33 strains), Escherichia coli (25 strains), and Pseudomonas aeruginosa (23 strains). Fungi comprised 48 (19.7%) strains:the top 3 were Candida tropicalis (14 strains), Candida albicans (10 strains), Aspergillus and Pneumocystis jirovecii (7 strains each). The incidence of Acinetobacter baumannii, Stenotrophomonas maltophilia, and Pseudomonas aeruginosa were significantly higher in death group compared to survival group[9.0%（6/67）vs. 2.3%（4/177）, χ2＝3.971 ，P＝0.046; 9.0%（6/67）vs. 1.1%（2/177）, χ2＝7.080 ，P＝0.008;16.4%（11/67）vs. 6.8%（12/177）, χ2＝5.288 ，P＝0.021]. The samples of 57 cases were simultaneously detected by both culture and metagenomic next-generation sequencing (mNGS). Pathogens were detected in 25 cases by both culture and mNGS. In 30 cases, pathogen detection were mNGS positive but culture negative. Two cases showed positive results only with culture. A total of 79 (46.8%) strains were multi-drug resistant bacteria, including 27 (34.2%) strains of gram-positive bacteria and 52 (65.8%) strains of gram-negative bacteria. A total of 174 (86.1%) children with sepsis received empirical anti-infective drugs within 24 hours of fever onset. A total of 124 (61.4%) cases were appropriately covered by the initial empirical antibiotics, while 40 (19.8%) cases were not adequately covered and 10 (5.0%) cases had incomplete coverage. Despite the inclusion of pathogenic in the coverage, resistance to initial antibiotics was observed in 22 (10.9%) cases. Fifty-one patients died. Conclusion:The predominant pathogens responsible for sepsis in PICU with hematological disorders and cancers is gram-negative bacteria, followed by gram-positive bacteria and fungi. In comparison to healthy children with sepsis, there is a higher incidence of fungal infections among hematological disorders and cancers. The proportion of multi-drug resistant bacteria infection is high. Early identification and combination of local etiological distribution and drug resistance, along with the empirical selection of appropriate anti-infection treatment strategies, can greatly enhance survival rate.

Microbiological environmental contamination in a Pediatric Intensive Care Unit / Contaminação ambiental microbiológica em Unidade de Terapia Intensiva Pediátrica / Contaminación ambiental microbiológica en una Unidad de Cuidados Intensivos Pediátricos

Background and objectives: inanimate surfaces and equipment in the hospital environment are considered reservoirs of resistant and pathogenic microorganisms. In Pediatric Intensive Care Units, the risk of infection is also related to the severity of pathologies associated with the immaturity of the immune system of this population. This study aimed to investigate microbiological environmental contamination in a Pediatric Intensive Care Unit. Method: this is an exploratory cross-sectional study, carried out in a Pediatric Intensive Care Unit of a highly complex university hospital, located in southern Brazil. To assess environmental contamination, sterile swabs were rubbed on surfaces corresponding to the patient unit and in the common area. Results: twenty-eight surfaces were analyzed, 12 of which were located in units occupied by patients at the time of collection and 16 surfaces in the common use area. In the total number of surfaces analyzed by microbiological cultures, the patient unit showed 66.67% contamination by microorganisms, while surfaces in the common area showed 56.25%. Regarding the microbiological profile, all isolated microorganisms were Gram-positive and showed resistance, namely Staphylococcus aureus and coagulase-negative Staphylococcus. Conclusion: there was evidence of a high frequency of contamination on inanimate surfaces and equipment near and far from patients, essentially by pathogenic and multi-resistant microorganisms to antimicrobials.(AU)

Justificativa e objetivos: superfícies e equipamentos inanimados no ambiente hospitalar são considerados reservatórios de microrganismos resistentes e patogênicos. Nas Unidades de Cuidados Intensivos Pediátricos, o risco de infeção também está relacionado com a gravidade das patologias associadas à imaturidade do sistema imunitário desta população. Este estudo teve como objetivo investigar a contaminação microbiológica ambiental em uma Unidade de Terapia Intensiva Pediátrica. Método: trata-se de um estudo exploratório transversal, realizado em uma Unidade de Terapia Intensiva Pediátrica de um hospital universitário de alta complexidade, localizado no Sul do Brasil. Para avaliar a contaminação ambiental, foram esfregados swabs estéreis nas superfícies correspondentes à unidade do paciente e na área comum. Resultados: foram analisadas vinte e oito superfícies, sendo 12 localizadas em unidades ocupadas por pacientes no momento da coleta e 16 superfícies em área de uso comum. No total de superfícies analisadas por culturas microbiológicas, a unidade paciente apresentou 66,67% de contaminação por microrganismos, enquanto as superfícies da área comum apresentaram 56,25%. Quanto ao perfil microbiológico, todos os microrganismos isolados eram Gram-positivos e apresentavam resistência, nomeadamente Staphylococcus aureus e Staphylococcus coagulase-negativa. Conclusão: houve evidência de elevada frequência de contaminação em superfícies inanimadas e equipamentos próximos e distantes dos pacientes, essencialmente por microrganismos patogênicos e multirresistentes aos antimicrobianos.(AU)

Fundamento y objetivos: las superficies y equipos inanimados del ambiente hospitalario son considerados reservorios de microorganismos resistentes y patógenos. En las Unidades de Cuidados Intensivos Pediátricos el riesgo de infección también se relaciona con la gravedad de patologías asociadas a la inmadurez del sistema inmunológico de esta población. Este estudio tuvo como objetivo investigar la contaminación ambiental microbiológica en una Unidad de Cuidados Intensivos Pediátricos. Método: se trata de un estudio exploratorio transversal, realizado en una Unidad de Cuidados Intensivos Pediátricos de un hospital universitario de alta complejidad, ubicado en el sur de Brasil. Para evaluar la contaminación ambiental se frotaron hisopos estériles en las superficies correspondientes a la unidad de pacientes y en el área común. Resultados: se analizaron veintiocho superficies, 12 de las cuales estaban ubicadas en unidades ocupadas por los pacientes en el momento de la recogida y 16 superficies en el área de uso común. Del total de superficies analizadas por cultivos microbiológicos, la unidad de pacientes presentó un 66,67% de contaminación por microorganismos, mientras que las superficies del área común presentaron un 56,25%. En cuanto al perfil microbiológico, todos los microorganismos aislados fueron Gram positivos y presentaron resistencia, concretamente Staphylococcus aureus y Staphylococcus coagulasa negativo. Conclusión: se evidenció alta frecuencia de contaminación en superficies inanimadas y equipos cercanos y lejanos de los pacientes, esencialmente por microorganismos patógenos y multirresistentes a los antimicrobianos.(AU)

Evaluación de la disfunción inmunológica en una unidad de cuidado intensivo pediátrico: un estudio observacional / Evaluation of immune dysfunction in a pediatric intensive care unit: an observational study

Resumen Introducción: La disfunción inmunológica en el paciente críticamente enfermo es un compromiso de un sistema muy poco estudiado; adicionalmente, en la población infantil aún faltan guías que orienten la evaluación del sistema inmunológico. Objetivo: Determinar la asociación de disfunción inmunológica y los desenlaces en los pacientes que ingresan a la unidad de cuidado intensivo pediátrico. Materiales y método: Estudio observacional, con componente analítico, llevado a cabo durante cuatro años, en el que se revisaron los expedientes de todos los pacientes pediátricos consecutivos con estancia en la unidad de cuidados intensivos a quienes, por criterios médicos, se les realizó perfil inmunológico. Resultados: Durante el período de estudio se reportaron 188 pacientes quienes cumplieron con los criterios de inclusión. Se presentó disfunción inmunológica en el 83% de los casos y enfermedad cardiaca en el 65%. La disfunción inmunológica se asoció con peores desenlaces medidos en mortalidad (37 vs. 9%; p = 0.0021), tiempo de estancia mayor a 14 días (46 vs. 14%; p < 0.0001) y disfunción multiorgánica (72 vs. 25%; p < 0.0001). Conclusión: La disfunción inmunológica es frecuente en los pacientes que ingresan a la unidad de cuidado intensivo pediátrico y se asocia con un aumento de la mortalidad, la duración de la ventilación mecánica invasiva y la duración de la estancia en la unidad de cuidado intensivo pediátrico. Muchos factores se asociaron con el desarrollo de disfunción inmunológica en esta población. Se necesitan estudios prospectivos para dilucidar el manejo óptimo de la disfunción inmunológica en el paciente crítico.

Abstract Introduction: Immune dysfunction in critical patients has not been clearly defined and has been insufficiently researched, particularly in pediatrics. Guidelines to standardize the immune system assessment and for routine use in clinical practice are lacking. Objective: To determine the association between immune dysfunction (here understood as the reduction of immunoglobulins and/or of the absolute count or populations of lymphocytes) and the outcome of patients admitted to the pediatric intensive care unit. Materials and method: This was an observational, analytical, descriptive, retrospective study, conducted over four years. The records of all patients who were admitted to the pediatric intensive care unit and had an immunity profile done were included in the database. Demographic and clinical variables were compared between patients with and without immune dysfunction. Results: A total of 188 patients with an immune profile were identified; 83% of patients had immune dysfunction and 65% had heart disease. The presence of immune dysfunction was associated with worse outcomes measured in mortality (37 vs. 9% p = 0.0021), length of stay greater than 14 days (46 vs. 14%; p < 0.0001) and multiple organ dysfunction syndrome (72 vs. 25%; p < 0.0001). Conclusion: Immune dysfunction is frequent in patients with a difficult disease course and in our study sample. It was found to be associated with increased mortality, duration of invasive mechanical ventilation and length of stay in the pediatric intensive care unit. Further prospective studies with other biomarkers are needed to determine the immune compromise and its impact on outcomes in the critically ill children.

Impacto de la implementación de un protocolo de sedoanalgesia en una unidad de cuidados intensivos pediátricos / Impact of the implementation of a sedation and analgesia protocol in a pediatric intensive care unit

Introducción. La adecuada sedación y analgesia es fundamental en el tratamiento de pacientes que requieren asistencia ventilatoria mecánica (AVM). Se recomienda la utilización de protocolos y su monitoreo; son dispares los resultados reportados sobre adhesión e impacto. Objetivos. Evaluar el impacto de la implementación de un protocolo de sedoanalgesia sobre el uso de benzodiacepinas, opioides y evolución en la unidad de cuidados intensivos pediátricos (UCIP), en pacientes que requieren AVM mayor a 72 horas. Métodos. Estudio tipo antes-después, no controlado, en la UCIP de un hospital pediátrico. Se desarrolló en 3 etapas: preintervención de diagnóstico situacional (de abril a septiembre de 2019), intervención y posintervención de implementación del protocolo de sedoanalgesia, educación sobre uso y monitorización de adherencia y su impacto (de octubre de 2019 a octubre de 2021). Resultados. Ingresaron al estudio 99 y 92 pacientes en las etapas pre- y posintervención, respectivamente. Presentaron mayor gravedad, menor edad y peso en el período preintervención. En la comparación de grupos, luego de ajustar por gravedad y edad, en la etapa posintervención se reportó una reducción en los días de uso de opioides en infusión continua (6 ± 5,2 vs. 7,6 ± 5,8; p = 0,018) y los días de uso de benzodiacepinas en infusión continua (3,3 ± 3,5 vs. 7,6 ± 6,8; p = 0,001). No se observaron diferencias significativas en los días de AVM y en los días totales de uso de benzodiacepinas. Conclusión. La implementación de un protocolo de sedoanalgesia permitió reducir el uso de fármacos en infusión continua.

Introduction. Adequate sedation and analgesia is essential in the management of patients requiring mechanical ventilation (MV). The implementation of protocols and their monitoring is recommended; mixed results on adherence and impact have been reported. Objectives. To assess the impact of the implementation of a sedation and analgesia protocol on the use of benzodiazepines, opioids, and evolution in the pediatric intensive care unit (PICU) in patients requiring MV for more than 72 hours. Methods. Before-and-after, uncontrolled study in the PICU of a children's hospital. The study was developed in 3 stages: pre-intervention for situational diagnosis (from April to September 2019), intervention, and post-intervention for implementation of a sedation and analgesia protocol, education on use, and monitoring of adherence and impact (from October 2019 to October 2021). Results. A total of 99 and 92 patients were included in the study in the pre- and post-intervention stages, respectively. Patients had a more severe condition, were younger, and had a lower weight in the preintervention period. After adjusting for severity and age, the group comparison in the post-intervention stage showed a reduction in days of continuous infusion of opioids (6 ± 5.2 versus 7.6­5.8, p = 0.018) and days of continuous infusion of benzodiazepines (3.3 ± 3.5 versus 7.6 ± 6.8, p = 0.001). No significant  differences were observed in days of MV and total days of benzodiazepine use. Conclusion. The implementation of a sedation and analgesia protocol resulted in a reduction in the use of continuous infusion of drugs.

Research status of screening and evaluation tool in pediatric delirium / 中国小儿急救医学

Early identification and intervention is very important in pediatric delirium.The pediatric confusion assessment method for the ICU and the cornell assessment of pediatric delirium are recommended to screen and evaluate pediatric delirium.We can also choose the appropriate tool according to children′s age, anesthesia status and drug use.Objective evaluation tool has been investigated as well, including biomarkers, imaging studies, electroencephalogram and so on.Electroencephalogram has some typical features, which is related to the occurrence of delirium.For the further research, we should look deep into quantitative electroencephalogram and multimodality model to evaluate and predict delirium.

Etiology composition and prognosis of pediatric chronic critical illness in a pediatric intensive care unit / 中国当代儿科杂志

OBJECTIVES@#To explore the etiology composition and outcomes of pediatric chronic critical illness (PCCI) in the pediatric intensive care unit (PICU).@*METHODS@#The children who were hospitalized in the PICU of Dongguan Children's Hospital Affiliated to Guangdong Medical University and met the diagnostic criteria for PCCI from January 2017 to December 2022 were included in the study. The etiology of the children was classified based on their medical records and discharge diagnoses. Relevant clinical data during hospitalization were collected and analyzed.@*RESULTS@#Among the 3 955 hospitalized children in the PICU from January 2017 to December 2022, 321 cases (8.12%) met the diagnostic criteria for PCCI. Among the 321 cases, the most common etiology was infection (71.3%, 229 cases), followed by unintentional injury (12.8%, 41 cases), postoperation (5.9%, 19 cases), tumors/immune system diseases (5.0%, 16 cases), and genetic and chromosomal diseases (5.0%, 16 cases). Among the 321 cases, 249 cases (77.6%) were discharged after improvement, 37 cases (11.5%) were discharged at the request of the family, and 35 cases (10.9%) died in the hospital. Among the deaths, infection accounted for 74% (26/35), unintentional injury accounted for 17% (6/35), tumors/immune system diseases accounted for 6% (2/35), and genetic and chromosomal diseases accounted for 3% (1/35). From 2017 to 2022, the proportion of PCCI in PICU diseases showed an increasing trend year by year (P<0.05). Among the 321 children with PCCI, there were 148 infants and young children (46.1%), 57 preschool children (17.8%), 54 school-aged children (16.8%), and 62 adolescents (19.3%), with the highest proportion in the infant and young children group (P<0.05). The in-hospital mortality rates of the four age groups were 14.9% (22/148), 8.8% (5/57), 5.6% (3/54), and 8.1% (5/62), respectively. The infant and young children group had the highest mortality rate, but there was no statistically significant difference among the four groups (P>0.05).@*CONCLUSIONS@#The proportion of PCCI in PICU diseases is increasing, and the main causes are infection and unintentional injury. The most common cause of death in children with PCCI is infection. The PCCI patient population is mainly infants and young children, and the in-hospital mortality rate of infant and young children with PCCI is relatively high.

Risk factors and correlation with prognosis of epileptic seizures in 284 pediatric patients in pediatric intensive care unit with electroencephalography monitoring / 中华实用儿科临床杂志

Objective:To illustrate the onset of epileptic seizures in children with brain injury admitted in pediatric intensive care unit (PICU), and to explore the risk factors and the correlation between epileptic seizures and the prognosis.Methods:Clinical data of pediatric patients with brain injury who were admitted to PICU of Peking University First Hospital from January 2013 to December 2019, and monitored by video electroencephalography (VEEG) were retrospectively collected, including general demographic information, etiological data, clinical seizures prior to VEEG performing, in-hospital mortality, brain function score, VEEG manifestations, etc.Seizures detected by VEEG were the primary outcome, and prognosis when discharged from PICU was the secondary outcome. Logistic regression was used to analyze the factors associated with seizures and poor outcome. Results:A total of 284 children were included, involving 54.9%(156/284) males.The median age of included children was 1.7(0.5, 5.0) years.Stratified by the cause of disease, 45.1%(128/284) had epilepsy, 26.1%(74/128) had genetic metabolic disease, and 14.4%(41/284) had central nervous system infection.A total of 82.0%(233/284) children had abnormal VEEG background activities, and 59.5%(169/284) had interictal epileptic discharges.Seizures were detected in 106 cases, including 39.6%(42/106) of non-convulsive seizures and 24.5%(26/106) of non-convulsive epileptic states.There were 12.0% (34/284) had poor prognosis at discharge, including 24 patients died in-hospital, and Pediatric Cerebral Performance Category scores were increased in 10 survivors.Multivariate Logistic regression analysis showed that seizures existed before VEEG monitoring and interictal epileptiform discharge were the independent risk factors for seizure.Besides, mental retardation, sepsis related encephalopathy, consciousness abnormality during VEEG, abnormal VEEG background activity, and epileptic status were significantly correlated with the poor prognosis of children with brain injury in PICU. Conclusions:The incidence of electrographic seizure is higher in children with brain injury in PICU, and VEEG monitoring is beneficial to children with brain injury that achieves an early identification of seizures and prediction of prognosis.

Influence of different admission sources on the outcome of children in pediatric intensive care unit / 中国小儿急救医学

Objective:To explore the relationship between different admission sources and outcomes at children in pediatric intensive care unit(PICU).Methods:The clinical data of children admitted to PICU of Henan Provincial People′s Hospital from January 1, 2021 to December 31, 2021 were collected.The children were divided into emergency group, outpatient group, ward transfer group and out-hospital transfer group according to different admission sources, and the influence of different admission sources on the outcome of children was analyzed.Results:A total of 413 children were included in the study.There were 141 cases(34.14%)in emergency group, 14 cases(3.39%)in outpatient group, 115 cases(27.85%)in ward transfer group and 143 cases(34.62%)in out-hospital transfer group.There were significant differences among the four groups in terms of age, length of hospital stay, PCIS score, type of disease, duration of mechanical ventilation and outcome of children( P<0.05). There was no significant difference in gender among the four groups( P=0.328). Among the 143 children of out-hospital transfer group, 92 cases(64.3%)were admitted during the day and 51 cases(35.7%)were admitted in the night.There was no significant difference in age, gender, duration of mechanical ventilation, PCIS score, length of hospital stay and outcome of children between two groups( P>0.05). The independent risk factors for mortality of children in out-hospital transfer group were length of hospital stay( OR=0.717, 95% CI 0.582-0.883, P=0.002), gender( OR=13.185, 95% CI 2.044-85.061, P=0.007), duration of mechanical ventilation>1 day( OR=23.524, 95% CI 3.294-168.026, P=0.002)and PCIS score≤80( OR=6.000, 95% CI 1.637-21.985, P=0.007). Conclusion:PICU children in our hospital mainly come from emergency, ward transfer and out-hospital transfer.The patients transferred from other hospitals were the most critically ill and had the worst outcome, suggesting that we need to develop and popularize referral standards for critically ill children and establish a transport system so that children can receive timely referral and effective treatment, so as to reduce the risk of death of referred children as far as possible.

The value of monitoring regional cerebral oxygen saturation in the prognosis assessment of comatose children in PICU / 中国小儿急救医学

Objective:To evaluate the value of monitoring regional cerebral oxygen saturation (rSO 2) in the prognosis of comatose children in pediatric intensive care unit (PICU). Methods:A total of 127 coma children who admitted to PICU at Henan Children′s Hospital from January 2019 to September 2021 were collected and divided into mild[Glasgow coma score(GCS): 13-15], moderate(GCS: 9-12) and severe coma(GCS: 3-8) groups according to GCS.A cerebral oxygen monitor was used to monitor the rSO 2 of all children before treatment, and on the 3rd, 7th and 14th day after treatment.The outcomes were assessed according to the pediatric cerebral performance category (PCPC), and the children were divided into recovery group(PCPC score: 1), disability group(PCPC score: 2-4) and poor prognosis group(PCPC score: 5-6). Multiple linear regression and receiver operating characteristic(ROC) curve were used to analyze the correlation between rSO 2 and PCPC score. Results:rSO 2 in mild, moderate and severe coma groups before treatment were (78.06±3.21)%, (66.07±6.05)%, and (52.87±6.49)%, respectively ( F=209.263, P<0.05). rSO 2 before treatment was positively correlated with GCS( r=0.806, P<0.05). There were significant differences in rSO 2 among recovery group, disability group and poor prognosis group before treatment and that on the 3rd, 7th and 14th day after treatment ( P<0.05). Notably, rSO 2 in recovery group was higher than that in disability group, and rSO 2 in disability group was higher than that in poor prognosis group.The rSO 2 of three groups showed an increasing trend over time ( P<0.05). Multiple linear regression analysis showed that rSO 2 on the 7th and 14th day of treatment were independent prognostic factors ( OR -0.042, 95% CI -0.082~0.003, P<0.05; OR -0.047, 95% CI -0.094~0.000, P<0.05). ROC analysis showed that rSO 2 on the 7th day of treatment had a relatively higher prognostic value for children in coma, and the area under the ROC curve for predicting the prognosis of abnormal brain function and no wakefulness were 0.741 and 0.746, respectively. Conclusion:Monitoring rSO 2 has predictive value for the prognosis of brain function of coma children in PICU, in which the prognostic value of rSO 2 on the 7th day after treatment is relatively higher and can be used as a reference index for prognosis assessment of coma children in PICU.

Comparison of Full Outline of Unresponsiveness Score and Glasgow Coma Scale for Assessment of Consciousness in Children With Acute Encephalitis Syndrome

Objectives: To correlate the Full outline of unresponsiveness (FOUR) score and Glasgow coma scale (GCS) in the assessment of children with acute encephalitis syndrome (AES). Method: This observational study was conducted in the department of pediatrics of a public sector tertiary care center from January, 2019 to March, 2020. All consecutive patients of AES admitted during the study period (n=150) were recruited. Subjects were analyzed using the FOUR score and GCS on admission, and then 12-hourly till discharge/ death. Treatment-related and demographic variables were collected and analyzed. Correlation between FOUR score and GCS scores was calculated using spearman correlation coefficient. Results: Positive correlation was observed between the GCS score and the FOUR score (n=0.82; P<0.001). Conclusion: FOUR score and GCS were comparable to assess the level of consciousness in patients with AES. The possibility of using FOUR score as an alternative to GCS in children with AES needs to be considered.

Introduction: In developing countries, in addition to comorbidities, other factors could increase the risk of severe respiratory disease. The objective of this study was to analyze the clinical, sociodemographic, and environmental risk factors associated with admission to the pediatric intensive care unit (PICU) of infants younger than 24 months with a diagnosis of bronchiolitis. Materials and methods: the study design was case-control. Infants from 0 to 24 months of age with a diagnosis of severe bronchiolitis who were admitted to the PICU were included, and the controls were infants with mild to moderate bronchiolitis, without PICU requirement. Cases with incomplete medical records and the inability to communicate with parents were excluded. Variables: low birth weight, preterm delivery and presence of underlying diseases (UD), socioeconomic level, exclusive breastfeeding (EBF) up to 6 months of age, exposure to environmental smoke and tobacco. Data were analyzed in SPSS V21. The hospital ethics committee approved the study and parental informed consent was obtained. Results: 220 patients were included. Control case 1:1. In the bivariate analysis, the cases were associated with the presence of UD, low birth weight, prematurity, low socioeconomic status, and absence of EBF for up to 6 months. In the adjusted analysis, severe bronchiolitis was associated with the presence of UD, low socioeconomic status, and absence of EBF up to 6 months. Conclusions: Severe bronchiolitis in infants under 24 months of age was associated with the presence of comorbidities, lack of exclusive breastfeeding, and belonging to low socioeconomic strata.
