Review Meta Analysis
Neuromuscular Blocking Agents for ARDS: A Systematic Review and Meta-Analysis.
Studies evaluating neuromuscular blocking agents (NMBAs) in the management of ARDS have produced inconsistent results in terms of their effect on mortality. The purpose of this systematic review and meta-analysis was to evaluate differences in mortality comparing subjects with ARDS who received NMBA to those who received placebo or usual care. ⋯ In subjects with ARDS, early use of NMBAs improves oxygenation, reduces the incidence of ventilator-induced lung injury, and decreases 21-28-d mortality, but it does not improve 90-d mortality. NMBAs should be considered for select patients with moderate-to-severe ARDS for short durations.

The high frequency of aerosolizing procedures in the ICU, including endotracheal intubation, places clinical staff at elevated risk of contracting the 2019 coronavirus (COVID-19). Use of an intubation checklist can reduce exposure risk and thus acts as a potential safeguard. Specific, step-by-step guidance to perform safe endotracheal intubation in the setting of COVID-19 are limited. This article outlines the development and refinement of a COVID-19 intubation checklist and operational protocol for ICU staff at a single center in the United States. ⋯ We present a checklist for use during high-risk intubations of COVID-19 patients, which serves as a pragmatic bedside tool for clinicians. The process of checklist development may also serve as a model for facilities preparing their own pandemic protocols.

Review Meta Analysis
Spontaneous Breathing Trials in Preterm Infants: Systematic Review and Meta-Analysis.
Few data are available on the use of spontaneous breathing trials (SBTs) in the neonatal population, despite advocacy of the practice in many neonatal ICUs. In this meta-analysis, we systematically reviewed the literature regarding the accuracy of SBTs as a predictor for extubation failure in premature infants. ⋯ The SBT in premature infants can accurately predict extubation success but not extubation failure. Therefore, even though it is an attractive, practical, and easy-to-perform bedside assessment tool, there is a lack of evidence to support its use as an independent predictor of extubation failure in premature infants. Its routine use should be evaluated and monitored carefully.

Congenital diaphragmatic hernia is associated with a high risk of neonatal mortality and long-term morbidity due to lung hypoplasia, pulmonary hypertension, and prolonged exposure to positive-pressure ventilation. Ventilator-associated lung injury may be reduced by using approaches that facilitate the transition from invasive ventilation to noninvasive ventilation (NIV), such as with neurally-adjusted ventilatory assist (NAVA). We reported our use of NAVA in neonatal patients with congenital diaphragmatic hernia during the transition from invasive ventilation to NIV. ⋯ Both invasive ventilation with NAVA and NIV with NAVA were used successfully in subjects with congenital diaphragmatic hernia during the transition from invasive ventilation to NIV. The transition to NAVA was associated with a decrease in peak inspiratory pressure, mean airway pressure, and the need for supplemental oxygen. A prospective trial is needed to determine the short- and long-term impacts of this mode of ventilation in neonates with congenital diaphragmatic hernia.

Oxygen therapy represents the elective therapy to improve the quality of life for patients with chronic respiratory diseases like COPD and interstitial lung disease. Lightweight portable oxygen concentrators (POCs) are a valid alternative to traditional systems such as portable compressed oxygen cylinders. However, patient preference and the possible psychological implications related to the use of both devices have been poorly assessed. We sought to evaluate patient preference between the ambulatory oxygen systems (ie, a POC or a small cylinder) for patients with COPD and interstitial lung disease experiencing exertional desaturation in a rehabilitation setting. Furthermore, the use of one device in comparison with the other was related to specific mechanical characteristics and related to perceived quality of life, anxiety, and depressive symptoms. ⋯ The POC and the portable compressed oxygen cylinder performed in a comparable manner during 6MWT for subjects with COPD and interstitial lung disease and exertional desaturation. Subjects preferred the POC because it was associated with better mobility.
