Normal values for maximal respiratory pressures in children and adolescents: A systematic review with meta-analysis.

BACKGROUND: The non-invasive assessment of maximal respiratory pressures (MRP) reflects the strength of the respiratory muscles. OBJECTIVE: To evaluate the studies which have established normative values for MRP in healthy children and adolescents and to synthesize these values through a meta-analysis. METHODS: The searches were conducted until October 2023 in the following databases: ScienceDirect, MEDLINE, CINAHL, SciELO, and Web of Science. Articles that determined normative values and/or reference equations for maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) in children and adolescents published in English, Portuguese, or Spanish regardless of the year of publication were included. Two reviewers selected titles and abstracts, in case of conflict, a third reviewer was consulted. Articles that presented sufficient data were included to conduct the meta-analysis. RESULTS: Initially, 252 studies were identified, 28 studies were included in the systematic review and 19 in the meta-analysis. The sample consisted of 5798 individuals, and the MIP and MEP values were stratified by sex and age groups of 4-11 and 12-19 years. Values from females 4-11 years were: 65.8 cmH2O for MIP and 72.8 cmH2O for MEP, and for males, 75.4 cmH2O for MIP and 84.0 cmH2O for MEP. In the 12-19 age group, values for females were 82.1 cmH2O for MIP and 90.0 cmH2O for MEP, and for males, they were 95.0 cmH2O for MIP and 105.7 cmH2O for MEP. CONCLUSIONS: This meta-analysis suggests normative values for MIP and MEP in children and adolescents based on 19 studies.

Pediatric unplanned extubation risk score: A predictive model for risk assessment.

BACKGROUND: Unplanned extubation is one of the most common preventable adverse events associated with invasive mechanical ventilation. OBJECTIVE: This research study aimed to develop a predictive model to identify the risk of unplanned extubation in a pediatric intensive care unit (PICU). METHODS: This single-center, observational study was conducted at the PICU of the Hospital de Clínicas. Patients were included based on the following criteria: aged between 28 days and 14 years, intubated, and using invasive mechanical ventilation. RESULTS: Over 2 years, 2,153 observations were made using the Pediatric Unplanned Extubation Risk Score predictive model. Unplanned extubation occurred in 73 of 2,153 observations. A total of 286 children participated in the application of the Risk Score. This predictive model was created to categorize the following significant risk factors: 1) inadequate placement and fixation of the endotracheal tube (odds ratio 2.00 [95%CI,1.16-3.36]), 2) Insufficient level of sedation (odds ratio 3.00 [95%CI,1.57-4.37]), 3) age ≤ 12 months (odds ratio 1.27 [95%CI,1.14-1.41]), 4) presence of airway hypersecretion (odds ratio 11.00 [95%CI,2,58-45.26]) inadequate family orientation and/or nurse to patient ratio (odds ratio 5.00 [95%CI,2.64-7.99]), and 6) weaning period from mechanical ventilation (odds ratio 3.00 [95%CI,1.67-4.79]) and 5 risk enhancement factors. CONCLUSIONS: The scoring system demonstrated effective sensitivity for estimating the risk of UE with the observation of six aspects, which overlap as an isolated risk factor or are associated with a risk enhancement factors.

Confiabilidade intra e interexaminadores da aplicação da Escala Motora Infantil de Alberta (EMIA) em ambulatório de seguimento de recém-nascidos de risco / Fiabilidad intraevaluadores e interevaluadores de la aplicación de la Escala Motora Infantil de Alberta (EMIA) en un seguimiento ambulatorio de recién nacidos de riesgo / Intra-and inter-examiner reliability of Alberta Infant Motor Scale application in follow-up ambulatory of at-risk newborns

RESUMO A prematuridade é fator de risco para atraso do desenvolvimento motor, e recomenda-se o acompanhamento desses lactentes nos primeiros dois anos de vida. Verificar a confiabilidade intra e interexaminadores da Escala Motora Infantil de Alberta (EMIA) em ambulatório de seguimento de recém-nascidos de risco de uma maternidade pública. Estudo prospectivo realizado em ambulatório de seguimento de recém-nascidos de risco. As avaliações do desenvolvimento motor foram realizadas por meio da EMIA, por dois avaliadores previamente treinados. O Coeficiente de Correlação Intraclasse (CCI) foi utilizado para análise das confiabilidades. Para a comparação entre as avaliações intraexaminadores foi realizado o Teste T pareado ou Teste de Wilcoxon. O Teste T independente foi utilizado para comparar as avaliações interexaminadores. A correlação entre as variáveis foi analisada a partir do Teste de Pearson ou Spearman. Para avaliar a concordância entre os escores foi realizada análise de Bland Altman. Foram avaliados 31 recém-nascidos pré-termo (RNPT) com idade corrigida média de 8,47 ± 4,49. Não houve diferença significativa entre as avaliações intraexaminadores e interexaminadores. Os valores de CCI se mantiveram acima de 0,88 para a confiabilidade intraexaminadores e interexaminadores. Os escores apresentaram alta concordância, analisada por meio do teste de Bland Altman. EMIA apresentou adequada confiabilidade intra e interexaminadores para avaliação e acompanhamento de RNPT até 18 meses em ambulatório de seguimento de lactentes de risco.

RESUMEN La prematuridad es un factor de riesgo de retraso en el desarrollo motor de los lactantes y se recomienda la monitorización de ellos durante los dos primeros años de vida. Verificar la fiabilidad intraevaluadores e interevaluadores de la Escala Motora Infantil de Alberta (EMIA) en un seguimiento ambulatorio de recién nacidos de riesgo en una maternidad pública brasileña. Estudio prospectivo realizado en un seguimiento ambulatorio de recién nacidos de riesgo. Para evaluar el desarrollo motor, la EMIA fue empleada por dos evaluadores previamente capacitados. Se utilizó el coeficiente de correlación intraclase (CCI) para analizar la fiabilidad. Para comparar las evaluaciones intraevaluadores, se utilizó la prueba T pareada o la prueba de Wilcoxon. La prueba T independiente se utilizó para comparar las evaluaciones interevaluadores. La correlación entre las variables se analizó mediante la prueba de Pearson o Spearman. Para evaluar la concordancia entre los puntajes, se aplicó el análisis de Bland Altman. Se evaluaron a 31 recién nacidos pretérmino (RNPT) con un promedio de edad media corregida de 8,47 ± 4,49. No hubo diferencias significativas entre las evaluaciones intraevaluadores e interevaluadores. Los valores de CCI se mantuvieron por encima de 0,88 para la fiabilidad intraevaluadores e interevaluadores. Los puntajes mostraron un alto nivel de concordancia, que se analizó mediante el Bland Altman. La EMIA apuntó una adecuada fiabilidad intra e interevaluadores para evaluar y monitorear los RNPT hasta 18 meses en seguimiento ambulatorio de lactantes de riesgo.

ABSTRACT Prematurity is a risk factor for delayed motor development, and it is recommended to monitor these infants in the first two years of life. To verify the properties of intra and inter-examiner measurements of AIMS in an outpatient follow-up clinic for newborns at risk in a public maternity hospital. Prospective study conducted in an outpatient follow-up of high-risk newborns. The Intraclass Correlation Coefficient (ICC) was used to analyze reliability. To compare the intra-examiner evaluations, the paired T-test or Wilcoxon test was performed. The independent T-test was used to compare inter-examiner assessments. The correlation between variables was analyzed using the Pearson or Spearman test. The Bland Altman test was performed to assess the concordance between the scores. 31 preterm infants with 8,47 ± 4,49 of corrected age were evaluated. There was no significant difference between the evaluations intra and inter-examiner. The ICC values remained above 0.88 for both intra and inter-examiner evaluation. The scores showed high agreement. AIMS has intra- and inter-examiner reliability for assessing and monitoring preterm newborns for up to 18 months in a follow-up clinic.
