Fluid overload: clinical outcomes in pediatric intensive care unit

Abstract Objective The aim of this study was to analyze the effects of fluid overload related to mechanical ventilation, renal replacement therapy, and evolution to discharge or death in critically ill children. Methods A retrospective study in a Pediatric Intensive Care Unit for two years. Patients who required invasive ventilatory support and vasopressor and/or inotropic medications were considered critically ill. Results 70 patients were included. The mean age was 6.8 ± 6 years. There was a tolerable increase in fluid overload during hospitalization, with a median of 2.45% on the first day, 5.10% on the third day, and 8.39% on the tenth day. The median fluid overload on the third day among those patients in pressure support ventilation mode was 4.80% while the median of those who remained on controlled ventilation was 8.45% (p = 0.039). Statistical significance was observed in the correlations between fluid overload measurements on the first, third, and tenth days of hospitalization and the beginning of renal replacement therapy (p = 0.049) and between renal replacement therapy and death (p = 0.01). The median fluid overload was 7.50% in patients who died versus 4.90% in those who did not die on the third day of hospitalization (p = 0.064). There was no statistically significant association between death and the variables sex or age. Conclusions The fluid overload on the third day of hospitalization proved to be a determinant for the clinical outcomes of weaning from mechanical ventilation, initiation of renal replacement therapy, discharge from the intensive care unit, or death among these children.

High and low-fidelity simulation for respiratory diseases pediatric training: a prospective and randomized study.

OBJECTIVE: To compare high and low-fidelity simulations for the recognition of respiratory distress and failure in urgency and emergency pediatric scenarios. METHODS: 70 fourth-year medical students were randomly distributed in high and low-fidelity groups and simulated different types of respiratory problems. Theory tests, performance checklists, and satisfaction and self-confidence questionnaires were used in the assessment. Face-to-face simulation and memory retention was applied. The statistics were evaluated by averages and quartiles, Kappa, and generalized estimating equations. The p-value was considered 0.05. RESULTS: In the theory test there was an increase in scores in both methodologies (p < 0.001); in memory retention (p = 0.043) and at the end of the process the high-fidelity group had better results. The performance in the practical checklists was better after the second simulation (p > 0,05). The high-fidelity group felt more challenged in both phases (p = 0.042; p = 0.018) and showed greater self-confidence to recognize changes in clinical conditions and in memory retention (p = 0.050). The same group, in relation to the hypothetical real patient to be treated in the future, felt better confident to recognize respiratory distress and failure (p = 0.008; p = 0.004), and better prepared to make a systematic clinical evaluation of the patient in memory retention (p = 0.016). CONCLUSION: The two levels of simulations enhance diagnostic skills. High fidelity improves knowledge, leads the student to feel more challenged and more self-confident in recognizing the severity of the clinical case, including memory retention, and showed benefits regarding self-confidence in recognizing respiratory distress and failure in pediatric cases.

Hipertensão arterial em crianças e adolescentes / Arterial hipertension in children and adolescents

A hipertensão arterial em pediatria é definida por níveis pressóricos iguais ou superiores ao percentil 95 para idade, sexo e estatura após três medidas sucessivas de pressão arterial (PA), tomadas pelo mesmo examinador em visitas diferentes, utilizando-se equipamento e técnica adequados. Embora a pressão arterial predomine na idade adulta, sua prevalência em criança e adolescentes não é desprezível, variando de 1,20 a 13% nos diversos estudos nacionais e internacionais. Neste artigo de revisão são abordados aspectos gerais de hipertensão arterial em crianças e adolescentes (definição, classificação, etiologia), sua abordagem diagnóstica e terapêutica e suas complicações.
