Review Meta Analysis
Effectiveness of diaphragmatic ultrasound as a predictor of successful weaning from mechanical ventilation: a systematic review and meta-analysis.
Several measurements have been used to predict the success of weaning from mechanical ventilation; however, their efficacy varies in different studies. In recent years, diaphragmatic ultrasound has been used for this purpose. We conducted a systematic review and meta-analysis to evaluate the effectiveness of diaphragmatic ultrasound in predicting the success of weaning from mechanical ventilation. ⋯ Measurement of diaphragmatic excursion and diaphragmatic thickening fraction predict the probability of successful weaning from mechanical ventilation with satisfactory diagnostic accuracy; however, significant heterogeneity was evident in the different included studies. Studies of high methodological quality in specific subgroups of patients in intensive care units are needed to evaluate the role of diaphragmatic ultrasound as a predictor of weaning from mechanical ventilation.

The aim of this study was to assess the safety and efficacy of 2 protocols for automatic lung recruitment maneuvers (LRMs) using stepwise increases in PEEP in a neonatal ARDS model. These protocols were designed with lower maximum opening pressures than traditional methods and differ each one in the duration of the opening phases (short vs prolonged). We described hemodynamic changes through invasive monitoring, and we analyzed if the behavior of the variables depends on the duration of the opening phase of the LRM. ⋯ Our LRM protocols exceeded critical opening pressures to reverse alveolar collapse in our neonatal ARDS model. This range of pressures might involve less hemodynamic disturbance. Duration of the maximum opening pressure step is a determining factor for hemodynamic alterations.

Meta AnalysisEarly versus late tracheostomy for traumatic brain injury: a systematic review and meta-analysis.
Tracheostomy is the most frequent bedside surgical procedure performed on patients with traumatic brain injury who require mechanical ventilation. To compare the effects of early tracheostomy vs. late tracheostomy on the duration of mechanical ventilation in patients with traumatic brain injury, we carried out a systematic review and meta-analysis. ⋯ The findings from this meta-analysis suggest that early tracheostomy in severe TBI patients contributes to a lower exposure to secondary insults and nosocomial adverse events, increasing the opportunity of patient's early rehabilitation and discharge.

One-Year Functional Outcomes After Invasive Mechanical Ventilation for Older Adults With Preexisting Long-Term Care-Needs.
To examine 1-year functional outcomes after invasive mechanical ventilation for adults greater than or equal to 65 years with preexisting long-term care-needs. ⋯ Among patients in preexisting care-needs levels 2-5 who received invasive mechanical ventilation, 76.0-79.2% died or had worsened care-needs within 1 year. These findings may aid shared decision-making among patients, their families, and heath care professionals on the appropriateness of starting invasive mechanical ventilation for people with poor functional and cognitive status at baseline.
