Review Meta AnalysisSubglottic Secretion Drainage and Objective Outcomes: A Systematic Review and Meta-Analysis.
Current guidelines recommend endotracheal tubes with subglottic secretion drainage to prevent ventilator-associated pneumonia. Subglottic secretion drainage is associated with fewer ventilator-associated pneumonia diagnoses, but it is unclear to what extent this reflects fewer invasive pneumonias versus fewer false-positive diagnoses due to less secretions and/or less microbial colonization of the oropharynx. We, therefore, undertook a systematic review and meta-analysis of the impact of subglottic secretion drainage on duration of mechanical ventilation, ICU and hospital length of stay, ventilator-associated events, mortality, antibiotic utilization, stridor, and reintubations to better understand the net benefits and limitations of this intervention. ⋯ Subglottic secretion drainage is associated with lower ventilator-associated pneumonia rates but does not clearly decrease duration of mechanical ventilation, length of stay, ventilator-associated events, mortality, or antibiotic usage. Further data are required to demonstrate the benefits of subglottic secretion drainage.

Review Meta AnalysisIncidence and Mortality of Acute Respiratory Distress Syndrome in Children: A Systematic Review and Meta-Analysis.
Our understanding of the acute respiratory distress syndrome in children is limited, and literature is dominated by investigations in adult patients. Recent preclinical studies suggest that the susceptibility to and severity of acute respiratory distress syndrome in children could differ from that in adults. We assessed the incidence and mortality of acute respiratory distress syndrome reported in children in studies published in the last two decades. ⋯ This systematic review and meta-analysis shows a low incidence but a high mortality. Its results also indicate that both incidence and mortality of pediatric acute respiratory distress syndrome have not changed over the last two decades and that mortality depends on the geographic location of studies.
