TLDR
The authors discuss the effects and implications of atelectasis in the perioperative period and illustrate how preventive measures may impact outcome and the impact of atElectasis and its prevention in acute lung injury.Abstract:
Atelectasis occurs in the dependent parts of the lungs of most patients who are anesthetized. Development of atelectasis is associated with decreased lung compliance, impairment of oxygenation, increased pulmonary vascular resistance, and development of lung injury. The adverse effects of atelectasis persist into the postoperative period and can impact patient recovery. This review article focuses on the causes, nature, and diagnosis of atelectasis. The authors discuss the effects and implications of atelectasis in the perioperative period and illustrate how preventive measures may impact outcome. In addition, they examine the impact of atelectasis and its prevention in acute lung injury.read more

Alveolar recruiting maneuver in dogs under general anesthesia: effects on alveolar ventilation, gas exchange, and respiratory mechanics
TL;DR: Lung aeration and gas exchange improved significantly 5 min after the RM compared to baseline and returned to values similar to baseline by 30 min and Static lung compliance was not significantly affected by the RM.

TL;DR: In patients undergoing LRS, prophylactic CPAP during the first 6 h after surgery with a pressure of 5-7 cm H2O improved the Pa(O 2)/FI(O2) ratio at 24 h, and this effect was more evident in patients with increased risk of postoperative pulmonary complications.

Intraoperative protective ventilation strategies in lung transplantation
TL;DR: Current approaches to protective mechanical ventilation in thoracic anaesthesia, with specific reference to intraoperative lung transplantation, are described, including low tidal volumes, pressure-controlled versus volume-controlled ventilation, positive end-expiratory pressure and alveolar recruitment manoeuvres.

Atelectasias perioperatorias y maniobras de reclutamiento alveolar
TL;DR: The frequency, pathophysiology, importance and treatment of peri-operative atelectasis is described, with special attention paid to treatment with recruitment manoeuvres, with the purpose of providing a basis for the their rational and appropriate use.

Helmet noninvasive mechanical ventilation in patients with acute postoperative respiratory failure.
TL;DR: NIV using a helmet could provide an effective alternative to conventional ventilation in selected patients with postoperative ARF and three factors were associated with respiratory failure: ARDS, pneumonia, and lack of improvement with NIV in 1 hour (increase in the PaO2/FIO2).

Ventilation with lower tidal volumes as compared with traditional tidal volumes for acute lung injury and the acute respiratory distress syndrome.
Roy G. Brower,Michael A. Matthay,Alan H. Morris,David A. Schoenfeld,B. Taylor Thompson,Arthur P. Wheeler +5 more
TL;DR: In patients with acute lung injury and the acute respiratory distress syndrome, mechanical ventilation with a lower tidal volume than is traditionally used results in decreased mortality and increases the number of days without ventilator use.

The acute respiratory distress syndrome
TL;DR: An overview of the definitions, clinical features, and epidemiology of the acute respiratory distress syndrome is provided and advances in the areas of pathogenesis, resolution, and treatment are discussed.

TL;DR: As compared with conventional ventilation, the protective strategy was associated with improved survival at 28 days, a higher rate of weaning from mechanical ventilation, and a lower rate of barotrauma in patients with the acute respiratory distress syndrome.

TL;DR: Mechanical ventilation can induce a cytokine response that may be attenuated by a strategy to minimize overdistention and recruitment/derecruitment of the lung, and these physiological improvements are associated with improvements in clinical end points.
