6. Clinical and laboratory studies on propofol
Sammanfattning : Patients undergoing major abdominal surgery were randomly given total intravenous anaesthesia based on propofol and fentanyl, anaesthesia based on propofol, fentanyl and nitrous oxide or anaesthesia based on isoflurane and fentanyl. Postoperative atelectasis demonstrated by computed tomography of the chest was found to a similar extent and a similar decrease in arterial oxygen pressure was seen in the groups. LÄS MER
7. Recruitment of small size lungs - experimental studies
Sammanfattning : Background: Patients - both children and adults - undergoing anesthesia and mechanical ventilation rapidly develop atelectasis. Even more severe problems occur in patients with acute lung injury/acute respiratory distress syndrome. LÄS MER
8. Airway pressure release ventilation : A systematic experimental approach
Sammanfattning : Airway pressure release ventilation (APRV) is a ventilatory mode which allows unrestrictedspontaneous breathing (SB) throughout the ventilatory cycle. If SB is insufficient, mechanicalventilatory support is achieved by brief periodic decreases of the airway pressure below the CPAPlevel. LÄS MER
9. Reducing Atelectasis during General Anaesthesia – the Importance of Oxygen Concentration, End-Expiratory Pressure and Patient Factors : A Clinical Study Exploring the Prevention of Atelectasis in Adults
Sammanfattning : Background: The use of pure oxygen during preoxygenation and induction of general anaesthesia is a major cause of atelectasis. The interaction between reduced lung volume, resulting in airway closure, and varying inspiratory fractions of oxygen (FIO2) in determining the risk of developing atelectasis is still obscure.

10. Atelectasis and gas exchange impairment after cardiopulmonary bypass : An experimental study
Sammanfattning : Despite of the improvement in management and equipment for cardiopulmonary bypass (CPB), postoperative pulmonary complications remain a major problem after cardiac surgery. In the present thesis, using a pig model, atelectasis has been tested as a cause of the increase in intrapulmonary shunt commonly seen after CPB. LÄS MER
