Longitudinal Analysis of Continuous Pulse Oximetry as Prognostic Factor in Neonatal Respiratory Distress.

OBJECTIVE: Analysis of longitudinal data can provide neonatologists with tools that can help predict clinical deterioration and improve outcomes. The aim of this study is to analyze continuous monitoring data in newborns, using vital signs to develop predictive models for intensive care admission and time to discharge. STUDY DESIGN: We conducted a retrospective cohort study, including term and preterm newborns with respiratory distress patients admitted to the neonatal ward. Clinical and epidemiological data, as well as mean heart rate and saturation, at every minute for the first 12 hours of admission were collected. Multivariate mixed, survival and joint models were developed. RESULTS: A total of 56,377 heart rate and 56,412 oxygen saturation data were analyzed from 80 admitted patients. Of them, 73 were discharged home and 7 required transfer to the intensive care unit (ICU). Longitudinal evolution of heart rate (p < 0.01) and oxygen saturation (p = 0.01) were associated with time to discharge, as well as birth weight (p < 0.01) and type of delivery (p < 0.01). Longitudinal heart rate evolution (p < 0.01) and fraction of inspired oxygen at admission at the ward (p < 0.01) predicted neonatal ICU (NICU) admission. CONCLUSION: Longitudinal evolution of heart rate can help predict time to transfer to intensive care, and both heart rate and oxygen saturation can help predict time to discharge. Analysis of continuous monitoring data in patients admitted to neonatal wards provides useful tools to stratify risks and helps in taking medical decisions. KEY POINTS: · Continuous monitoring of vital signs can help predict and prevent clinical deterioration in neonatal patients.. · In our study, longitudinal analysis of heart rate and oxygen saturation predicted time to discharge and intensive care admission.. · More studies are needed to prospectively prove that these models can helpmake clinical decisions and stratify patients' risks..

Prospective observational study on the use of continuous intravenous ketamine and propofol infusion for prolonged sedation in critical care.

INTRODUCTION: Analgesia and sedation are a priority in paediatric intensive care. The combination of ketamine and propofol is a possible option in patients requiring prolonged or difficult sedation and to reduce the use of benzodiazepines and opiates. The aim of this study was to assess the efficacy and safety of combination ketamine and propofol in continuous infusion for prolonged analgesia/sedation in the paediatric intensive care setting. PATIENTS AND METHODS: Prospective, observational single-group cohort study in patients aged 1 month to 16 years admitted to the paediatric intensive care unit in 2016-2018 that received ketamine and propofol in continuous infusion for analgesia and sedation. We collected data on demographic and clinical characteristics, analgesia and sedation scores (MAPS, COMFORT-B and SOPHIA), haemodynamic parameters and adverse events. RESULTS: The study included 32 patients. The maximum dose of ketamine was 1.5 mg/kg/h (interquartile range [IQR], 1-2 mg/kg/h) and the infusion duration was 5 days (IQR, 3-5 days). The maximum dose of propofol was 3.2 mg/kg/h (IQR, 2.5-3.6 mg/kg/h) and the infusion duration, 5 days (IQR, 3-5 days). Thirty (93.7%) patients had previously received midazolam and 29 (90.6%) fentanyl. Analgesia scores did not change after initiation of the ketamine and propofol infusion. There was a statistically significant increase in the COMFORT-B score, but the score remained in the adequate sedation range (12-17). There were small but statistically significant decreases in the mean arterial pressure (from 64 mmHg to 60 mmHg; P = .006) and the diastolic blood pressure (from 50.5 to 48 mmHg; P = .023) 1 h after the initiation of the ketamine and propofol infusion, but this difference was not observed 12 h later and did not require administration of vasoactive drugs. No other major adverse events were detected during the infusion. CONCLUSIONS: The combination of ketamine and propofol in continuous infusion is a safe treatment in critically ill children that makes it possible to achieve an appropriate level of analgesia and sedation without relevant haemodynamic repercussions.

Fatal Staphylococcus Aureus Endocarditis Misdiagnosed as Multisystem Inflammatory Syndrome in Children.

We present a case of a 10-year-old male with Staphylococcus aureus mitral endocarditis who was initially misdiagnosed with multisystem inflammatory syndrome associated with coronavirus disease 2019, with eventual fatal outcome due to brain hemorrhage after cardiac intervention. Our case differs from recent studies, in which microbleeds did not increase the risk of hemorrhagic stroke or global mortality risk.

Do we overestimate intravenous fluid therapy needs? Adverse effects related to isotonic solutions during pediatric hospital admissions.

INTRODUCTION: Maintenance intravenous fluids are frequently used in hospitalised pediatric patients. The aim of the study was to describe the adverse effects of isotonic fluid therapy in hospitalised patients, and its prevalence based on the rate of infusion. MATERIALS AND METHODS: A prospective clinical observational study was designed. We included hospitalised patients between 3 months-old and 15-years-old were included with 0,9% isotonic solutions with 5% glucose within the first 24 h of administration. They were divided into two groups, depending on the quantity of liquid they received (restricted <100% vs 100% maintenance needs). Clinical data and laboratory findings were recorded in two different times (T0 when they were admitted to hospital and T1 within the first 24 h of administration). RESULTS: The study included 84 patients, 33 received <100% maintenance needs and 51 patients received around 100%. The main adverse effects notified in the first 24 h of administration were hyperchloremia >110 mEq/L (16.6%) and oedema (19%). Oedema was more frequent in patients with lower age (p < 0,01). The hyperchloremia at 24 h of intravenous fluids was an independent risk factor of developing oedema (OR 1,73 (1,0-3,8), p = 0,06). CONCLUSION: The use of isotonic fluids is not free from adverse effects, probably related to the rate of infusion and more likely to appear in infants. It`s necessary more studies that review the correct estimation of intravenous fluid needs in hospitalized children.

Uso concomitante de ketamina y propofol en perfusión continua en cuidados intensivos: eficacia y seguridad para analgesia y sedación prolongada / Prospective observational study on the use of continuous intravenous ketamine and propofol infusion for prolonged sedation in critical care

Introducción: La analgosedación es una prioridad en el cuidado de pacientes en unidades de intensivos pediátricos. La combinación de ketamina y propofol puede ser una alternativa para aquellos pacientes con necesidad de sedación prolongada, con dificultad para la sedación y para disminuir el empleo de benzodiacepinas y opiáceos. El objetivo de este estudio es analizar la eficacia y seguridad de la combinación de ketamina y propofol en perfusión continua para la analgosedación en unidades de cuidados intensivos pediátricos.Materiales y métodos: Estudio de cohorte única prospectivo observacional en pacientes de 1 mes a 16 años ingresados en unidades de cuidados intensivos pediátricos entre 2016 y 2018 que recibieron tratamiento con ketamina y propofol en perfusión continua para analgosedación. Se recogieron datos clínicos y demográficos, scores de analgesia y sedación (MAPS, COMFORT-B y SOPHIA), parámetros hemodinámicos y efectos adversos. Resultados: Treinta y dos pacientes fueron incluidos. La dosis máxima de ketamina fue de 1,5mg/kg/h (RI 1-2mg/kg/h) y la duración, 5 días (RI 3-5 días). La dosis máxima de propofol fue de 3,2mg/kg/hora (RI 2,5-3,6mg/kg/hora) y la duración, 5 días (RI 3-5 días). Treinta pacientes (93,7%) habían recibido midazolam y 29 (90,6%) fentanilo previamente. Tras el inicio de la perfusión de ketamina y propofol la puntuación en la escala de analgesia no se modificó. El COMFORT-B mostró un incremento estadísticamente significativo, pero se mantuvo dentro del rango de sedación adecuada (12-17). Se produjo una leve disminución en la presión arterial media tras una hora de administración, que fue estadísticamente significativa (de 64mmHg a 60mmHg; P=0,006) así como en la presión arterial diastólica (de 50,5 a 48mmHg; P=0,023). Esta diferencia desapareció a las 12 horas del inicio y no requirió uso de drogas vasoactivas. No se detectaron efectos adversos graves durante la administración. (AU)

¿Sobreestimamos las necesidades de líquidos? Complicaciones del uso de sueros isotónicos de mantenimiento en plantas de hospitalización pediátrica / Do we overestimate intravenous fluid therapy needs? Adverse effects related to isotonic solutions during paediatric hospital admissions

Introducción: La fluidoterapia intravenosa es un tratamiento ampliamente utilizado en pacientes pediátricos hospitalizados. El objetivo del estudio fue analizar las complicaciones asociadas al uso de sueros isotónicos de mantenimiento en pacientes hospitalizados y comparar la frecuencia de aparición de estas complicaciones con distintos ritmos de administración. Materiales y métodos: Se realizó un estudio observacional y prospectivo, en el que se incluyeron pacientes hospitalizados de entre tres meses y 15 años de edad que recibieron tratamiento con fluidoterapia isotónica 0,9% con glucosa al 5% durante las primeras 24 horas de ingreso. Se dividieron en dos cohortes según el ritmo de fluidoterapia: restringido<100% vs. no restringido cercano al 100% necesidades basales (NNBB), calculadas según la regla de Holliday y Segar. Se recogieron variables clínicas y analíticas en dos tiempos de estudio (T0 al ingreso y T1 a las 24 horas de la fluidoterapia). Se realizó un estudio uni y multivariante para identificar factores de riesgo de complicaciones. Resultados: Se incluyeron 84 pacientes, de los cuales 33 recibieron fluidoterapia restringida y 51 pacientes con 100% NNBB. Las principales complicaciones desarrolladas en las primeras 24 horas fueron hipercloremia> 110 mEq/L (16,6%) y edemas (19%). La aparición de edemas fue más frecuente en pacientes de menor edad (p <0,01) y la hipercloremia se asoció con el desarrollo de edemas (OR 1,73 [1,0-3,8]), p=0,06. Conclusiones: La administración de sueros isotónicos no está exenta de complicaciones, probablemente relacionadas con el ritmo de administración y más frecuentes en lactantes. Son necesarios estudios que revisen las necesidades de líquidos en niños hospitalizados. (AU)
