2. 6. Influence of tidal volume on pulmonary gas exchange during general anaesthesia

   Author : Bruno Enekvist; Anestesiologi och intensivvård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anaesthesia; sevoflurane; cardiac output; functional residual capacity; pulmonary gas exchange;

   Abstract : Background and objective: General anaesthesia impairs respiratory function. The present studies were performed to compare arterial concentration of sevoflurane, oxygen and carbon dioxide in normal and overweight patients ventilated with increased tidal volume (VT), or normal tidal volume with and without PEEP.

4. 7. Measuring global surgery, obstetrics and anaesthesia from health systems to patients

   Author : Hampus Holmer; Lund Pediatrik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Global Health; Health statistics; Surgery; Obstetrics; Anaesthesia;

   Abstract : BackgroundWorldwide, an estimated 5 billion people lack access to safe, affordable surgical care when needed. This leads to millions of avertable deaths and unnecessary morbidity each year. To change this situation, urgent action is needed at many levels, but indicators and data have been lacking to guide improvement. READ MORE

5. 8. 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

   Author : Lennart Edmark; Mats Enlund; Göran Hedenstierna; Sten Lindahl; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesia; general. Lung: Atelectasis; CPAP; Oxygen; PEEP; Ventilation; mechanical; Tomography; X-ray computed.; Anestesiologi; Anaesthesiology; Fysiologi; Physiology;

   Abstract : 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.

6. 9. Blood pressure-dependent changes in plasma volume, glycocalyx and platelet function during anaesthesia -Clinical and experimental studies

   Author : Tor Damén; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anaesthesia; blood pressure; hypotension; norepinephrine; haematocrit; plasma volume; atrial natriuretic peptide; glycocalyx; platelet aggregation;

   Abstract : Background: Worldwide, more than 300 million surgeries are performed each year. General anaesthesia provides the surgical patient with a state of controlled loss of sensation and awareness. It is common that general anaesthesia causes hypotension. Anaesthesia-induced hypotension is associated with haemodilution and increased plasma volume (PV). READ MORE

7. 10. Influence of depth of anesthesia on postoperative cognitive dysfunction (POCD) and inflammatory markers

   Author : Pether Jildenstål; Narinder Rawal; Lars Berggren; Jan Jakobsson; Johan Reader; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Postoperative cognitive dysfunction; minor and major surgery; anaesthesia; depth of anaesthesia monitoring; auditory evoked potential; AAI; inflammatory marker; Medicin; Medicine;

   Abstract : Patients may suffer from various forms of postoperative cognitive dysfunction (POCD). In most cases, the impact on cognitive function is relatively transient but POCD can sometimes be long-lasting (> 1 year). Studies showing that up to one in four patients with known risk factors are affected by some form of cognitive loss. READ MORE
