Description of a Swine Infant Model of Volume-Controlled Hemorrhagic Shock.

Hemorrhagic shock is a leading cause of morbidity and mortality in pediatric patients. Interpretation of the clinical indicators validated in adults to guide resuscitation and comparison between different therapies is difficult in children due to the inherent heterogeneity of this population. As a result, compared to adults, appropriate management of pediatric hemorrhagic shock is still not well established. In addition, the scarcity of pediatric patients with hemorrhagic shock precludes the development of clinically relevant studies. For this reason, an experimental pediatric animal model is necessary to study the effects of hemorrhage in children as well as their response to different therapies. We present an infant animal model of volume-controlled hemorrhagic shock in anesthetized young pigs. Hemorrhage is induced by withdrawing a previously calculated blood volume, and the pig is subsequently monitored and resuscitated with different therapies. Here, we describe a precise and highly reproducible model of hemorrhagic shock in immature swine. The model yields hemodynamic data that characterizes compensatory mechanisms that are activated in response to severe hemorrhage.

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)

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 1.5mg/kg/h (interquartile range [IQR], 1–2mg/kg/h) and the infusion duration was 5 days (IQR, 3–5 days). The maximum dose of propofol was 3.2mg/kg/h (IQR, 2.5–3.6mg/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 64mmHg to 60mmHg; P=.006) and the diastolic blood pressure (from 50.5 to 48mmHg; P=.023) 1h after the initiation of the ketamine and propofol infusion, but this difference was not observed 12h later and did not require administration of vasoactive drugs. No other major adverse events were detected during the infusion. (AU)

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.

Multicenter randomized clinical trial comparing dexamethasone versus placebo in preventing upper airway obstruction after extubation in critically ill children.

To analyze the effectiveness of dexamethasone in preventing upper airway obstruction (UAO) symptoms after extubation and the need of reintubation in critically ill children. Multicenter, prospective, double-blind, randomized, phase IV clinical trial involving five pediatric intensive care units. Children between 1 month and 16 years-of-age intubated for more than 48 h were included. Patients were randomized to receive placebo or dexamethasone 0.25 mg/kg every 6 h, 6-to-12 h prior to extubation (four doses). 48 h follow-up was carried out after extubation. Severity of UAO symptoms (Taussig score, stridor) and reintubation requirement were compared. 147 patients were randomized (10 were excluded), 70 patients received dexamethasone and 67 placebo. No global differences were found in the presence of stridor or moderate-to-severe UAO symptoms (Taussig ≥ 5), but Taussig ≥ 5 was less frequent in patients less than 2 years-of-age treated with steroids (p = 0.014). Median Taussig score was lower in the dexamethasone group 1 h after extubation, p < 0.001. 27 patients required reintubation, 9 due to UAO: 3 (4.3%) in the dexamethasone group and 6 (8.9%) in the placebo group, p = 0.319. In those intubated > 5 days, reintubation due to UAO was higher in the placebo group (2.4% vs. 14.3, p = 0.052). Nebulized epinephrine and budesonide were required more frequently in the placebo group in the first 2 h (p = 0.041) and 1 h (p = 0.02) after extubation, respectively. No relevant side effects were observed. Dexamethasone prior to extubation did not significantly reduce moderate-severe UAO symptoms, except for patients under 2-years of age. Dexamethasone could decrease Taussig score and the need of rescue therapies, as well as reintubation rates in those intubated for more than 5 days.

Streptococcus agalactiae: causa de artritis séptica inusual a partir de los 3 meses de edad. Caso clínico / Streptococcus agalactiae: an unusual cause of septic arthritis beyond 3 months of age. Case report

La artritis séptica es una patología poco frecuente, pero con una alta morbilidad, debido a las importantes secuelas que puede originar. La etiología varía según la edad, y Staphylococcus aureus es el microorganismo más frecuente en todas ellas. Streptococcus agalactiae odel grupo B es una causa infrecuente de infección fuera del período neonatal; se asocia, a partir de los 3 meses de edad, con infecciones graves en pacientes inmunocomprometidos. El tratamiento de elección es penicilina G o ampicilina.Aquí se describe el caso de un niño de cuatro meses y medio de edad que desarrolló una artritis séptica por Streptococcus agalactiae odel grupo B, con inicio insidioso de la clínica. El diagnóstico etiológico obligó a descartar meningitis y una inmunodeficiencia asociada. La frecuencia extremadamente baja de dicha artritis a esta edad y la importancia de descartar una enfermedad diseminada son importantes puntos de aprendizaje en este caso.

Septic arthritis is not a very frequent disease, but with a high morbidity due to the important sequelae that it can cause. The etiology is age-specific, with Staphylococcus aureus being the most frequent microorganism in all ages. Streptococcus agalactiae or group B Streptococcus is an uncommon cause of infection outside the neonatal period. Beyond 3 months of age, infections by this pathogen are associated with serious infections in immunocompromised patients. The treatment of choice is penicillin G or ampicillin. A 4.5-month-old child who developed a group B Streptococcus septic arthritis is reported. The onset was insidious, and the etiological diagnosis prompted us to rule out meningitis and associated immunodeficiency. The extremely low frequency of group B Streptococcus septic arthritis at this age and the importance of ruling out a disseminated disease are crucial learning points in this case

Evaluación del manejo del dolor de la patología facial y oral en un Servicio de Urgencias Pediátrico y tras el alta domiciliaria / Assessment of orofacial pain management in a pediatric emergency department and at home after discharge

Introducción. El manejo inadecuado del dolor es frecuente en Urgencias. El objetivo fue analizar el manejo del dolor de niños con patología infecciosa o traumática del área facial/oral en Urgencias y evaluar el cumplimiento y satisfacción sobre la analgesia prescrita al momento del alta. Población y métodos. Estudio transversal, observacional y analítico en niños que acudieron a Urgencias con patología infecciosa/traumática de la región facial/oral durante 2 meses. Se recogieron el manejo del dolor en Urgencias, la analgesia prescrita para el domicilio y, tras el contacto telefónico con los padres, el tratamiento realizado y su adecuación al dolor del niño. Resultados. Fueron incluidos 252 pacientes (edad media de 4,5 años, desvío estándar 3,89). En 8,7%, figuraba la evaluación del dolor en triaje y, en 3,6%, en el informe médico. Se administró analgesia en Urgencias al 41,3%. Al momento del alta, en un 13,9%, no se prescribió analgesia; en 25,4%, se prescribió pautada y, en 60,3%, a demanda. Los pediatras usaron más analgesia pautada que los cirujanos (34,4% vs. 16,5%, p < 0,01). En el domicilio, no administraron analgesia en el 39,3%; en un 36,1%, pautada y, en un 23%, a demanda. Existió escasa correlación entre la pauta al momento del alta y la administrada en el domicilio (kappa: 0,178). Se consideró la analgesia adecuada en el 84%, con más frecuencia en patología traumática que infecciosa (85,7% vs. 14,3%, p < 0,01). Conclusiones. Se observó escasa evaluación y tratamiento del dolor en Urgencias. La prescripción más usada fue a demanda en vez de pautada, al contrario de lo recomendado en las guías. El control analgésico fue mejor en patología traumática que infecciosa.

Introduction. An inadequate pain management is common in the emergency department. Our objective was to analyze pain management among children with an orofacial infection or trauma in the emergency department and to assess compliance and satisfaction with analgesia prescribed at discharge. Population and methods. Cross-sectional, observational and analytical study in children attending the emergency department for an orofacial infection or trauma over 2 months. Pain management in the emergency department, analgesia prescribed at home and, following a call to parents, treatment provided and its adequacy to control pain were registered. Results. In total, 252patients (mean age: 4.5 years, SD: 3.89) were included. Pain assessment was recorded at the triage for 8.7%, and in the medical report, for 3.6%. Analgesia was administered to 41.3% in the emergency room. At discharge, no analgesia was prescribed to 13.9%; scheduled analgesia, to 25.4%; and as needed, to 60.3%. Pediatricians prescribed scheduled analgesia more frequently than surgeons (34.4% versus 16.5%, p < 0.01). At home, no analgesia was administered to 39.3%; scheduled analgesia, to 36.1%; and as needed, to 23%. There is little correlation between prescription at discharge and at home (Kappa: 0.178). Analgesia was considered adequate in 84% of cases, and was more frequent in trauma injuries than in infections (85.7% versus 14.3%, p < 0.01). Conclusions. Pain assessment and management was scarce in the emergency department. The most common prescription was as needed, contrary to what is recommended in the guidelines. Analgesic control worked better for trauma injuries than for infections.

[Frequent users in paediatric emergency departments. Who are they? Why do they consult?] / Hiperfrecuentadores en urgencias. ¿Quiénes son? ¿Por qué consultan?

OBJECTIVE: To determine the prevalence of frequent Paediatric Emergency Departments users and to analyse their characteristics, comparing initial consultations and re-consultations. METHODS: This is a multicentre retrospective cohort study of all patients who made 10 or more visits to the Paediatric Emergency Departments of 5 public hospitals between 1 January 2013 and 31 December 2013. An analysis was performed on the patient demographics and clinical data of the first consultation and consecutive re-consultations. RESULTS: Frequent users represented 0.60% (95% CI: 0.56-0.64%) of Emergency Department users, and accounted for 3.93% (95% CI: 3.47-4.39%) of all visits. The most numerous age group consisted of children under 2 years old (66.6%). Frequent users distributed their visits throughout the year (62.3%; P<.001), and did not have a chronic condition associated with their chief complaint (86.4%; P<.001). They were usually classified as non-urgent or less urgent in triage (3,186 vs. 1,812; P<.001), and often did not require any intervention, such as complementary tests (79.4%) or observation/treatment (60%). Admission rate was similar to the general paediatric population (5.3%). Re-consultations represented 27% of these patient visits, mostly related to persistence of symptoms (56.3%), with 13.8% of them consulting their Primary Care physician before seeking successive medical attention in the Paediatric Emergency Department. CONCLUSIONS: Paediatric frequent users often ask for medical care in the Emergency Department before consulting their Primary Care physician. They present with less urgent processes and do not systematically need diagnostic or therapeutic interventions. Re-consultations make up a significant number of visits, in which more interventions are done and more children are admitted.

A Rare Complex Case of Congenital Umbilical Arteriovenous Malformation and Review of Literature.

Introduction Congenital umbilical arteriovenous malformations (AVMs) are extremely rare. We present the first case of congenital umbilical AVM with feeding arteries originating not only from abdominal but also from the mammary arteries. Case Report A 34-week gestational age newborn was transferred to our hospital with a supraumbilical murmur. Abdominal Doppler ultrasound (US) showed a large vascular AVM, with multiple feeding arteries and several venous drainage structures to the umbilical vein and also a persistent ductus venosus. She developed signs of heart failure on the 12th day of life. Computed tomography angiogram revealed an umbilical congenital AVM with feeding arteries originating from the external iliac, hypogastric, epigastric, and mammary arteries and a dilated umbilical vein draining the cluster. Also, a patent ductus venosus was observed. At 14 days of life, laparotomy was performed but due to the complexity of the feeding arteries of the AVM, complete exeresis was not performed, but only ligation of these arteries was made, to reduce the surgical risk. Conclusion To our knowledge, this is the first time that no complete excision was made but only ligation of the arteries. The infant was discharged home on postoperative day 14 being asymptomatic. Follow-up Doppler US showed thrombosed vascular structures.
