Unplanned extubations (UEs) have been associated with increased ventilator days, risk of infection, cardiopulmonary resuscitation, and resuscitation medication usage. The UE rate in our level 4 NICU is lower than the national average. Efforts to further reduce UE events at our institution led an interdisciplinary group to define steps to eliminate UEs. Steps included: (1) requiring at least 2 care providers at the bedside for movement of an intubated subject; (2) standardizing head and endotracheal tube (ETT) position; (3) defining a set methodology for ETT securing; (4) introducing a postoperative handoff to improve communication; and (5) implementing a post-UE assessment tool. ⋯ The development of standard guidelines to prevent UE and a quality review process to track UE provided important information for education and practice change. In our NICU, these changes have significantly improved the UE rate through improved teamwork, accountability, and communication.

The prone posture is known to have numerous effects on gas exchange, both under normal conditions and in patients with ARDS. Clinical studies have consistently demonstrated improvements in oxygenation, and a multi-center randomized trial found that, when implemented within 48 h of moderate-to-severe ARDS, placing subjects in the prone posture decreased mortality. Improvements in gas exchange occur via several mechanisms: alterations in the distribution of alveolar ventilation, redistribution of blood flow, improved matching of local ventilation and perfusion, and reduction in regions of low ventilation/perfusion ratios. ⋯ The prone posture results in more uniform pulmonary blood flow when compared with the supine posture, due to an anatomical bias for greater blood flow to dorsal lung regions. Because both ventilation and perfusion heterogeneity decrease in the prone posture, gas exchange improves. Other benefits include a more uniform distribution of alveolar stress, relief of left-lower-lobe lung compression by the heart, enhanced secretion clearance, and favorable right-ventricular and systemic hemodynamics.

Randomized Controlled Trial Observational Study
Randomized Comparison of Helmet CPAP Versus High-Flow Nasal Cannula Oxygen in Pediatric Respiratory Distress.
The current study aimed to compare the efficacy and safety of 2 noninvasive respiratory support methods, which included helmet CPAP and high-flow nasal cannula (HFNC) in children with respiratory distress admitted to a pediatric intermediate care unit. ⋯ Based on our knowledge, the present study is the first research comparing the effects of CPAP and HFNC in respiratory distress resolution in a pediatric intermediate care setting. It aims to identify the most efficient treatment to avoid pediatric ICU admissions and endotracheal intubation and reduce the administration of drugs and days of hospitalization.

Clearing subglottic secretions has been proved to reduce ventilator-associated pneumonia. A manual method named the rapid flow expulsion maneuver was developed to clear subglottic secretions. This study evaluates its safety and effectiveness and analyzes the influential factors. ⋯ The rapid flow expulsion maneuver was safe and effective to clear subglottic secretions. The first maneuver was the most effective to expel the majority of secretions. Supine position and high peak flow improved the clearance efficiency.
