Objetivo: Foram avaliados conhecimentos e habilidades sobre reanimação cardiopulmonar antes e após a capacitação em Suporte Básico de Vida (SBV) para médicos e enfermeiros que atuam na atenção primária. Métodos: Estudo quasi-experimental, com amostra aleatória de profissionais. Inicialmente, avaliou-se o desempenho cognitivo em um teste de múltipla escolha sobre o atendimento a uma parada cardiorrespiratória (PCR) e, em seguida, conduziu-se um atendimento simulado de PCR, para a avaliação de habilidades, usando um checklist baseado nas recomendações da American Heart Association (AHA). Após avaliação inicial, todos os profissionais participaram de curso teórico-prático em SBV, durante três encontros. Após o curso, todos se submeteram a nova avaliação. Resultados: Participaram do estudo 32 profissionais. O nível de conhecimentos e habilidades foi insatisfatório antes do curso. Após a capacitação, a média de acertos na avaliação teórico-prática apresentou aumento significativo (p<0,001). Conclusão: Registrou-se impacto positivo da capacitação em SBV para os profissionais da atenção primária.

ObjectiveRenal resistive index (RRI) and renal pulsatility index (RPI) are Doppler-based variables proposed to assess renal perfusion at the bedside in critically ill patients. This study aimed to assess the accuracy of such variables to predict acute kidney injury (AKI) in mechanically ventilated children.DesignProspective single-center observational studySettingPediatric intensive care unit of a quaternary care teaching hospital.Patients84 children under controlled ventilation (median age of 5.1 months and weight of 6.6 kg).InterventionsConsecutive children underwent renal Doppler ultrasound examination within 24 hours of invasive mechanical ventilation. Renal resistive index (RRI) and renal pulsatility index (RPI) were measured. The primary outcome was severe AKI (KDIGO stage 2 or 3) on day 3. Secondary outcomes included the persistence of severe AKI on day 5.ResultsOn day 3, 22 patients were classified as having AKI (any stage), of which 12 were severe. RRI could effectively predict severe AKI (area under the ROC curve [AUC] 0.94; 95% CI 0.86 – 0.98; p < 0.001) as well as RPI (AUC 0.86; 95% CI 0.76 – 0.92; p < 0.001). The AUC of the IRR was significantly greater than that obtained from the RPI (p = 0.023). The optimal cutoff for RRI was 0.85 (sensitivity, 91.7%; specificity, 84.7%; positive predictive value, 50.0%; and negative predictive value 98.4%). Similar results were obtained when the accuracy to predict AKI on day 5 was assessed. Significant correlations were observed between RRI and estimated glomerular filtration rate at enrollment (ρ = -0.495, p<0.001) and on day 3 (ρ = -0.467, p <0.001).ConclusionsRenal Doppler ultrasound may be a promising tool to predict AKI in critically ill children under invasive mechanical ventilation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
