ReviewBest Practices for Managing Pain, Sedation, and Delirium in the Mechanically Ventilated Patient.
Nursing management of pain, agitation, and delirium in mechanically ventilated patients is a challenge in critical care. Oversedation can lead to delayed extubation, prolonged ventilator days, unnecessary neurologic testing, and complications such as weakness and delirium. ⋯ Acquiring an optimal level of sedation requires the bedside nurse to be more vigilant than ever with patient assessment and medication titration. This article provides a historical perspective of the management of pain, agitation, and delirium, and disseminates information contained in revised Society for Critical Care Medicine Clinical Practice Guidelines (January 2013) to promote their implementation in day-to-day nursing care.

ReviewNoninvasive Support: Does It Really Decrease Bronchopulmonary Dysplasia?
Noninvasive support of preterm infants with respiratory distress is an evidenced-based strategy to decrease the incidence of bronchopulmonary dysplasia. Continuous positive airway pressure (CPAP) is the only noninvasive strategy with sufficient evidence to support its use in acute respiratory distress syndrome. It is unclear if one method for delivering CPAP is superior to another. Future research will focus on strategies (eg, sustained lung inflation, and administration of surfactant using a thin plastic catheter) that increase the likelihood of success with CPAP, especially in infants with a gestational age of less than 26 weeks.

ReviewThe Changing Role for Tracheostomy in Patients Requiring Mechanical Ventilation.
Tracheostomy is performed in patients who require prolonged mechanical ventilation or have upper airway instability. Percutaneous tracheostomy with Ciaglia technique is commonly used and rivals the surgical approach. ⋯ Early tracheostomy decreases the need for sedation and intensive care unit stay but may be unnecessary in some patients who can be extubated later successfully. A multidisciplinary approach to tracheostomy care leads to improved outcomes.

Spontaneous breathing trials (SBTs) are among the most commonly employed techniques to facilitate weaning from mechanical ventilation. The preferred SBT technique, however, is still unclear. To clarify the preferable SBT (T-piece or pressure support ventilation [PSV]), we conducted this systematic review. ⋯ PSV may be associated with lower weaning failure rates in the simple-to-wean subgroup. In contrast, in prolonged-weaning subjects, T-piece may be related to a shorter weaning duration, although this is at high risk of bias. Further study of the difficult-to-wean and COPD subgroups is required.

The Centers for Disease Control and Prevention shifted the focus of safety surveillance in mechanically ventilated patients from ventilator-associated pneumonia to ventilator-associated events (VAEs) in 2013. The shift was designed to increase the objectivity and reproducibility of surveillance and to encourage quality-improvement programs to tackle a broader array of complications in mechanically ventilated patients. Prospective intervention studies have found that minimizing sedation, increasing the use of spontaneous awakening and breathing trials, and conservative fluid management can lower VAE rates and decrease duration of mechanical ventilation. Additional strategies to prevent VAEs include early mobility programs, low tidal volume ventilation, and restrictive transfusion thresholds.
