Objective To identify early prognostic factors that lead to an increased risk of unfavorable prognosis. Design Observational cohort study from October 2002 to October 2017. Setting and patients Patients with severe TBI admitted to intensive care were included. Variables and interventions Epidemiological, clinical, analytical and therapeutic variables were collected. The functional capacity of the patient was assessed at 6 months using the Glasgow Outcome Scale (GOS). An unfavorable prognosis was considered a GOS less than or equal to 3. A univariate analysis was performed to compare the groups with good and bad prognosis and their relationship with the different variables. A multivariate analysis was performed to predict the patient's prognosis. Results 98 patients were included, 61.2% males, median age 6.4 years (IQR 2.49–11.23). 84.7% were treated by the out-of-hospital emergency services. At 6 months, 51% presented satisfactory recovery, 26.5% moderate sequelae, 6.1% severe sequelae, and 2% vegetative state. 14.3% died. Statistical significance was found between the score on the prehospital Glasgow coma scale, pupillary reactivity, arterial hypotension, hypoxia, certain analytical and radiological alterations, such as compression of the basal cisterns, with an unfavorable prognosis. The multivariate analysis showed that it is possible to make predictive models of the evolution of the patients. Conclusions it is possible to identify prognostic factors of poor evolution in the first 24 h after trauma. Knowledge of them can help clinical decision-making as well as offer better information to families (AU)

Respiratory and pharmacological management in severe acute bronchiolitis: Were clinical guidelines not written for critical care?

PURPOSE: The treatment applied for children admitted to the pediatric intensive care unit (PICU) for severe acute bronchiolitis may differ from general recommendations. The first objective of our study was to describe the treatments offered to these children in a Spanish tertiary PICU. The second objective was to analyse the changes in management derived from the publication of the American Academy of Pediatrics (AAP) bronchiolitis guideline in 2014. METHODS: This was a retrospective-prospective observational study conducted during two epidemic waves (2014-2015 and 2015-2016). The AAP guidelines were distributed and taught to PICU staff between both epidemic waves. RESULTS: A total of 138 children were enrolled (78 male). In the first period, 78 children were enrolled. The median age was 1.8 months (IQR 1.1-3.6). There were no differences between the management in the two periods, except for the use of high-flow oxygen therapy (HFOT); its use increased in the second period. Overall, 83% of patients received non-invasive ventilation or HFOT. Children older than 12 months received HFOT exclusively. In comparison, continuous positive airway pressure and bi-level positive airway pressure were used less during the period 2015-2016 (P=0.036). Regarding pharmacological therapy, 70% of patients received antibiotics, 23% steroids, 33% salbutamol, 31% adrenaline, and 7% hypertonic saline. The mortality rate was zero. CONCLUSIONS: Our PICU did not follow the AAP recommendations. There were no differences between the two periods, except in the use of HFOT. All children older than 12 months received HFOT exclusively. The rate of using invasive mechanical ventilation was also low.

[Extreme reactive thrombocytosis in a healthy 6 year-old child]. / Trombocitosis extrema reactiva en un niño sano de 6 años.

Thrombocytosis is usually a casual finding in children. Reactive or secondary thrombocytosis is the more common form, being the infections diseases the most prevalent cause of it. Regarding the number of platelets there are four degrees of thrombocytosis; in its extreme degree the number of platelets exceeds 1,000,000/mm(3). We describe a case of extreme reactive thrombocytosis in a healthy 6-year-old child. He required critical care admission for diagnosis and treatment (maximum number of platelets 7,283,000/mm(3)). We review the different causes of thrombocytosis in childhood, the differential diagnosis, and the available treatments in case of extreme thrombocytosis.

Extreme reactive thrombocytosis in a healthy 6 year-old child.

Thrombocytosis is usually found by chance in children. Reactive or secondary thrombocytosis is the more common form, with infectious diseases being the most prevalent cause of it. Regarding the number of platelets there are four degrees of thrombocytosis; in its extreme degree the number of platelets exceeds 1,000,000/mm3. We describe a case of extreme reactive thrombocytosis in a healthy 6-year-old child. He required critical care admission for diagnosis and treatment (maximum number of platelets 7,283,000/mm3). We review the different causes of thrombocytosis in childhood, the differential diagnosis, and the available treatments in case of extreme thrombocytosis.

La trombocitosis es un hallazgo casual frecuente en pediatría. En niños, predominan las formas secundarias, siendo las infecciones su causa más prevalente. Se distinguen 4 grados de trombocitosis en función del número de plaquetas; en la forma extrema, se supera el 1.000.000/mm3. Se presenta un caso de trombocitosis extrema reactiva en un niño sano de 6 años, que requirió ingreso en cuidados intensivos para tratamiento y diagnóstico (cifra máxima de plaquetas de 7.283.000/mm3). Se revisan las diferentes causas de trombocitosis en la infancia, se describe el diagnóstico diferencial y se discute sobre los diferentes tratamientos disponibles ante un caso como el descrito.

[Staphylococcus aureus infections in the intensive care unit: clinical and epidemiological characteristics]. / Infecciones por Staphylococcus aureus en cuidados intensivos: características clínicas y epidemiológicas.

INTRODUCTION: There has been an increase in invasive Staphylococcus Aureus infections over the last few years, which have required admission to the pediatric intensive care unit (PICU). PATIENTS AND METHODS: All patients with S. aureus infection who were admitted to PICU were enrolled in a retrospective study (January 2006-June 2010). The patients were classified into 2 groups: community-acquired infection (Group 1) and nosocomial infection (Group 2). We recorded epidemiological data, type of S. aureus (methicillin-susceptible S. aureus [MSSA], methicillin-resistant S. aureus [MRSA]), risk factors, site of infection, presence of hemodynamic instability, respiratory support, and mortality. RESULTS: A total of 51 patients were enrolled, 21 belonging to Group 1 and 30 to Group 2. The median age was lower in Group 1 (1.6 years vs 3.2 years; P=.009). MSSA was isolated in 88% of cases. MRSA was detected in 6/51 (12%) of cases, which were isolated in the later study period (January 2009-June 2010). The risk factors for infection were: immunosuppression, venous catheter, institutionalization, mechanical ventilation, previous surgery, previous trauma and chronic osteomyelitis. A large majority (83%) of the patients with MRSA infection had risk factors. The type of infection was varied, with respiratory tract infection being the most common (75%). Hemodynamic instability was observed in 43% of patients. Most patients (86%) required respiratory support. One patient in Group 1 died of necrotizing pneumonia caused by MSSA. CONCLUSIONS: Infections by S. aureus in children are severe and have a high morbidity. Respiratory infection was the most common in our series. Isolation of MSSA is common in these infections, although, an increase in the number of infections by MRSA was observed during the latter part of the study.

[Severe bronchiolitis. Changes in epidemiology and respiratory support]. / Bronquiolitis grave. Cambios epidemiológicos y de soporte respiratorio.

INTRODUCTION: Bronchiolitis generates lots of admissions during the cold months in the paediatric intensive care units (PICU). New forms of respiratory support are being used and could improve the care of these patients. OBJECTIVES: To analyse the epidemiological and respiratory support changes of children admitted to the PICU. PATIENTS AND METHODS: An observational, retrospective, descriptive and analytical study of patients with the diagnosis of bronchiolitis admitted to the PICU of a tertiary hospital during the respiratory syncytial virus (RSV) epidemic months between 2005 and 2010. RESULTS: A total of 229 patients were admitted, of whom 83% were infected with RSV. The mean age was 1.48 months, with children under 3 months being the greatest number of admissions (73.3%). December was the month with the highest number of admissions (52%). Mortality was 0.9%. The mean time of stay in the PICU and on respiratory assistance were 4 and 3 days, respectively (no significant differences between the periods studied). Patients with RSV bronchiolitis were younger than the negative RSV (mean 2.61 months and 4.05 months, P=.023). Active respiratory support was required in 73% of cases. The percentage of patients who required active respiratory support increased over the years (Z=3.81, P=.00014), especially high flow nasal oxygen therapy (Z=3.62, P=.00028). An inverse relationship was observed between patient age and length of stay in PICU (Beta=-0.245, P ≤.0001) and days on respiratory support (Beta=-0.167, P=.039). CONCLUSIONS: Most patients admitted to the PICU are less than 3 months old. Mortality was 0.9%. Respiratory support (especially non-invasive mechanical ventilation and high flow nasal oxygen therapy) is used increasingly often. The youngest patients need more days in PICU and more respiratory support.
