2. 1. Pulmonary Atelectasis in General Anaesthesia : Clinical Studies on the Counteracting Effects of Positive End-Expiratory Pressure

   Author : Erland Östberg; Mats Enlund; Lennart Edmark; Sophie Lindgren; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General anaesthesia; pulmonary atelectasis; positive end-expiratory pressure; oxygen; computed tomography; continuous positive airway pressure; mechanical ventilation; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

   Abstract : Partial lung collapse, i.e., pulmonary atelectasis, is common during general anaesthesia. The main causal mechanism is reduced lung volume with airway closure and subsequent gas absorption from preoxygenated alveoli. READ MORE

4. 2. 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.

5. 3. 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. 4. Anaesthesia and Genetics of the Ryanodine 1 Receptor

   Author : Marcus Ewert Broman; Lund Institutionen för kliniska vetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General Anaesthesia; Ryanodine 1 Receptor; Malignant Hyperthermia; Genetics;

   Abstract : The only validated method to characterize the phenotype and to reach a definitive diagnosis of Malignant Hyperthermia Susceptibility (MHS; OMIM *145600), a pharmacogenetic disease linked to the Ryanodine 1 receptor gene (RYR1; OMIM *180901), is an invasive muscle contraction test requiring a muscle biopsy, according to the European (IVCT) protocol or to the North American (CHCT) protocol. The series of scientific papers in this thesis tries to reach as far as possible in diagnosing MHS from peripheral venous blood samples collected at the patients’ local primary care provider and sent to the laboratory over significant transportation time and distance.

7. 5. lmprovement in perioperative care of the day case patient; logistics and quality of care. : Anaesthesia impact in Day Surgery

   Author : Irene Sellbrant; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Day surgery; POP-surgery; Open hernia repair; Distal radial fracture; Anaesthetic technique; Supraclavicular block; Local anaesthesia; Long short-acting local anaesthetic agent; Logistics; Pain; Postoperative opioid consumption; Quality of care; QoR-15; Perioperative medicine;

   Abstract : Background: The “Day surgery concept” is increasing and nowadays numerous of surgical procedures in patients of all ages, with different comorbidities are performed as day case surgery. Day surgery (DS) is a process; not a procedure. READ MORE
