Tracheostomy in the Intensive Care Unit: a University Hospital in a Developing Country Study.
Introduction Tracheostomy is the commonest surgical procedure in intensive care units (ICUs). It not only provides stable airway and facilitates pulmonary toilet and ventilator weaning, but also decreases the direct laryngeal injury of endotracheal intubation, and improves patient comfort and daily living activity. Objective The objective of this study is to assess the incidence, indications, timing, complications (early and late), and the outcome of tracheostomy on patients in the intensive care units (ICU) at a university hospital in a developing country. ⋯ Complications after tracheostomy were 13.9% tracheal stenosis and 25% subglottic stenosis. Conclusion Prolonged endotracheal intubation is the man indication of tracheostomy, performed after two weeks of intubation. Although there were no major early complications, laryngotracheal stenosis is still a challenging sequel for tracheostomy that needs to be investigated to be prevented.

ReviewTranspulmonary Pressure: The Importance of Precise Definitions and Limiting Assumptions.
Recent studies applying the principles of respiratory mechanics to respiratory disease have used inconsistent and mutually exclusive definitions of the term "transpulmonary pressure." By the traditional definition, transpulmonary pressure is the pressure across the whole lung, including the intrapulmonary airways, (i.e., the pressure difference between the opening to the pulmonary airway and the pleural surface). However, more recently transpulmonary pressure has also been defined as the pressure across only the lung tissue (i.e., the pressure difference between the alveolar space and the pleural surface), traditionally known as the "elastic recoil pressure of the lung." Multiple definitions of the same term, and failure to recognize their underlying assumptions, have led to different interpretations of lung physiology and conclusions about appropriate therapy for patients. ⋯ These misconceptions include assertions that normal pleural pressure must be negative (subatmospheric) and that a pressure in the pleural space may not be substantially positive when a subject is relaxed with an open airway. We urge specificity and uniformity when using physiological terms to define the physical state of the lungs, the chest wall, and the integrated respiratory system.

ReviewSpecial Considerations in the Nursing Care of Mechanically Ventilated Children.
Mechanical ventilation is often required to support the recovery of critically ill children. Critical care nurses must understand the unique needs of the children and design supportive care that is sensitive to their changing physiology, developmental stage, and socioemotional needs. ⋯ It addresses invasive and noninvasive ventilation and the needs of long-term ventilated children and family in critical care. Supportive nursing care that is aligned with the unique needs of the critically ill child is paramount to ensuring best outcomes for these vulnerable patients.

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.
