1. 1. Lung Emphysema & Cardiac Function

   Författare :Kirsten Jörgensen; Göteborgs universitet; []
   Nyckelord :emphysema; hemodynamics; ventricular end-diastolic volumes; lung volume reduction; ventricular function; transoesophageal echocardiography; magnetic resonance imaging; diastole; simendan; hypertrophy;

   Sammanfattning : Patients with severe lung emphysema have poor quality of life because of impaired lung function and reduced exercise tolerance. Concomitant heart disease in severe emphysema is well recognised. The prevailing view is that mainly the right side of the heart is involved, while the issue of left ventricular (LV) involvement is less studied. LÄS MER

3. 2. Open and closed endotracheal suctioning. Experimental and human studies

   Författare :Sophie Lindgren; Göteborgs universitet; []
   Nyckelord :suctioning; endotracheal; closed system suctioning; monitoring; lung volume; airway pressure; lung recruitment; bronchoalveolar lavage; acute lung injury;

   Sammanfattning : Background: The practice of endotracheal suctioning of ventilator treated patients is necessary to remove secretions to prevent obstruction of the endotracheal-tracheal tube and lower airways. This very common procedure creates a large variety of heart-lung interferences. LÄS MER

4. 3. Ventilation distribution in the lung periphery measured by inert gas washout : influence of increased gravity, anti-G suit pressure, body posture, and breathing pattern

   Författare :Mikael Grönkvist; Göran Hedenstierna; Linköpings universitet; []
   Nyckelord :acceleration; anti-G suit; body posture; cdi; dcdi; human centrifuge; He; hypergravuty; lung; multiple-breath washout; single-breath washout; SF 6; standing; supune; trapped gas; ventilation distribution; MEDICINE; MEDICIN;

   Sammanfattning : The lung is highly sensitive to forces of gravity and acceleration, and to surrounding pressures. This thesis aimed to assess the effects on ventilation distribution in peripheral lung units when changing the direction or magnitude of the gravitational vector and when compressing the lower body half with an anti-G suit (AGS).

5. 4. Radiological imaging of pulmonary emphysema : preoperative evaluation of candidates for lung volume reduction surgery

   Författare :Kerstin Cederlund; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Computed tomography; quantitative computed tomography; emphysema; lung volume reduction surgery; lung scintigraphy.;

   Sammanfattning : Lung volume reduction surgery (LVRS) for pulmonary emphysema, first described by Brantigan in 1957, was re-introduced by Cooper et al in 1995. From a surgical point of view, information on the extent and distribution of emphysema is mandatory and also partly determines the outcome. LÄS MER

7. 5. The Immune Response to One-Lung Ventilation : Clinical and Experimental Studies

   Författare :Thomas Schilling; Göran Hedenstierna; Hans Hedenström; Thomas Hachenberg; Sven-Erik Ricksten; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; One-lung ventilation; open thoracic surgery; ventilation-induced lung injury; alveolar immune response; bronchoalveolar lavage; propofol; desflurane; cytokines; animal model; mRNA; RT-PCR; Medical laboratory science; Medicinsk laboratorievetenskap; anestesiologi; Anaesthesiology;

   Sammanfattning : One-lung ventilation (OLV) as an established procedure during thoracic surgery may be injurious in terms of increased mechanical stress characterised by alveolar cell stretch and overdistension, increased cyclic tidal recruitment of alveolar units, compression of alveolar vessels and increased pulmonary vascular resistance. This may result in ventilation-induced lung injury with pro-inflammatory cytokine production, leukocyte recruitment and neutrophil-dependent tissue destruction. LÄS MER
