Epinephrine in cardiac arrest: systematic review and meta-analysis

Objetivo: avaliar a efetividade da adrenalina na parada cardíaca e seu efeito na sobrevivência e no estado neurológico. Métodos: revisão sistemática da literatura científica com meta-análise utilizando um modelo de efeitos aleatórios. Revisão em Medline, Embase e Cochrane, desde 2005 até 2015 de ensaios clínicos e estudos observacionais. Resultados: observou-se aumento nas taxas de retorno de circulação espontânea com a administração de adrenalina (OR 2,02; 95% IC 1,49-2,75; I2=95%) comparadas com a não administração de adrenalina. A meta-análise mostrou um aumento da sobrevivência na alta ou depois de 30 dias da administração de adrenalina (OR 1,23; 95% IC 1,05-1,44; I2=83%). Quando estratificados por ritmos desfibrilháveis e não desfibrilháveis apareceu um aumento da sobrevivência nos ritmos não desfibrilháveis (OR 1,52; 95% IC 1,29-1,78; I2=42%). Também observou-se um incremento de sobrevivência na alta ou depois de 30 dias, quando administrada a adrenalina antes de 10 minutos, isto comparado com administração tardia (OR 2,03; 95% IC 1,77-2,32; I2=0%). Conclusão: a administração de adrenalina parece incrementar a taxa de retorno da circulação espontânea, mas não se tem encontrado um efeito positivo nas taxas de sobrevivência nem nas taxas de pacientes com estado neurológico favorável, em comparação com outras terapias.Objective: evaluate the effectiveness of epinephrine used during cardiac arrest and its effect on the survival rates and neurological condition. Method: systematic review of scientific literature with meta-analysis, using a random effects model. The following databases were used to research clinical trials and observational studies: Medline, Embase and Cochrane, from 2005 to 2015. Results: when the Return of Spontaneous Circulation (ROSC) with administration of epinephrine was compared with ROSC without administration, increased rates were found with administration (OR 2.02. 95% CI 1.49 to 2.75; I2 = 95%). Meta-analysis showed an increase in survival to discharge or 30 days after administration of epinephrine (OR 1.23; 95% IC 1.05-1.44; I2=83%). Stratification by shockable and non-shockable rhythms showed an increase in survival for non-shockable rhythm (OR 1.52; 95% IC 1.29-1.78; I2=42%). When compared with delayed administration, the administration of epinephrine within 10 minutes showed an increased survival rate (OR 2.03; 95% IC 1.77-2.32; I2=0%). Conclusion: administration of epinephrine appears to increase the rate of ROSC, but when compared with other therapies, no positive effect was found on survival rates of patients with favorable neurological status.Objetivo: evaluar la efectividad de la adrenalina en el paro cardíaco y su efecto en la supervivencia y en el estado neurológico.

La estratificación por ritmos desfibrilables y no desfibrilables mostró un aumento de la supervivencia en ritmos no desfibrilables (OR 1,52; 95% IC 1,29-1,78; I2=42%).

Conclusión: la administración de adrenalina parece incrementar la tasa de retorno de circulación espontánea, pero no se ha encontrado un efecto positivo en tasas de supervivencia ni en tasas de pacientes con estado neurológico favorable, en comparación con otras terapias

Mortality and critical conditions in COVID-19 patients at private hospitals: weekend effect?

OBJECTIVE: The aim of the study was to find factors associated with the mortality of admission to the intensive care unit (ICU) in patients with COVID-19. MATERIALS AND METHODS: Retrospective observational study with a database of 1987 patients with COVID-19 who had attended the emergency department of a private hospital network between February 2020 and April 2020 were analyzed. Clinical variables and some laboratory parameters were studied. The Charlson and Elixhauser comorbidity indices were calculated. The dependent variables were mortality and admission to the ICU. A descriptive and correlational analysis was performed. Logistic regression models and Kaplan-Meier survival curves were established. RESULTS: Positive correlations were observed between age, creatinine, and D-dimer levels, as well as with the scores obtained with the Charlson and Elixhauser indices. Differences in the levels of these parameters were also observed when analyzing variables such as mortality, sex or admission to the ICU. Mortality was associated with high creatinine and D-dimer levels and advanced age. Survival curves indicated longer survival in patients not admitted to the ICU, admitted to the hospital during the week, and in those with lower creatinine and D-dimer levels. CONCLUSIONS: Mortality in Spanish patients with COVID-19 admitted to private hospitals was associated with high creatinine and D-dimer levels and advanced age. Longer survival was obtained on weekdays. This study provides valuable information on the management and nursing care of these patients in order to optimize resources in pandemic situations.S

Nurse-Led Interventions in Chronic Obstructive Pulmonary Disease Patients: A Systematic Review and Meta-Analysis

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, causing 3.32 million deaths in 2019. COPD management has increasingly become a major component of general and hospital practice and has led to a different model of care. Nurse-led interventions have shown beneficial effects on COPD patient satisfaction and clinical outcomes. This systematic review was conducted to identify and assess nurse-led interventions in COPD patients in terms of mental, physical, and clinical status. The review was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. The relevance of each manuscript was assessed according to the inclusion criteria, and we retrieved full texts, as required, to reach our conclusions. Data extraction was performed independently by two reviewers, and the risk of bias was assessed using the Cochrane Risk of Bias tool. Forty-eight articles were included in the analysis, which focused on the management of COPD patients by hospital, respiratory and primary nursing care. Nursing management was shown to be highly effective in improving quality of life, emotional state, and pulmonary and physical capacity in COPD patients. In comparison, hospital and respiratory nurses carried out interventions with higher levels of effectiveness than community nurses
