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

    Författare :Erland Östberg; Mats Enlund; Lennart Edmark; Sophie Lindgren; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Synchronized delivery of inspired nitric oxide : Effects on oxygenation and pulmonary tension during artificial ventilation

    Författare :Erkki Heinonen; Tim Higenbottam; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; nitric oxide; pulsed administration; pulmonary hypertension; oxygenation; equine; Cellbiologi; Cell biology; Cellbiologi; Physiology; fysiologi;

    Sammanfattning : Nitric oxide (NO) is a mediator of vascular smooth muscle tension that metabolises rapidly in blood. NO delivered by inhalation can therefore be used as a selective pulmonary vasodilator to relieve pulmonary hypertension or to improve oxygenation with no systemic effects. LÄS MER

  4. 3. Effects of Deep Breathing Exercises after Coronary Artery Bypass Surgery

    Författare :Elisabeth Westerdahl; Arne Tenling; Göran Hedenstierna; Birgitta Lindmark; Anders Larsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical therapy; atelectasis; breathing exercises; coronary artery bypass; computed tomography; physiotherapy; postoperative care; postoperative complications; respiratory function tests; thoracic surgery; Sjukgymnastik; Physiotherapy; Sjukgymnastik fysioterapi;

    Sammanfattning : Deep breathing exercises are widely used in the postoperative care to prevent or reduce pulmonary complications, but no scientific evidence for the efficacy has been found after coronary artery bypass grafting (CABG) surgery. The aim of the thesis was to describe postoperative pulmonary function and to evaluate the efficacy of deep breathing exercises performed with or without a blow bottle device for positive expiratory pressure (PEP) 10 cmH2O or an inspiratory resistance-positive expiratory pressure (IR-PEP) mask with an inspiratory pressure of -5 cmH2O and an expiratory pressure of +10 to +15 cmH2O.

  5. 4. Open lung concept in high risk anaesthesia : Optimizing mechanical ventilation in morbidly obese patients and during one lung ventilation with capnothorax

    Författare :Henrik Reinius; Filip Fredén; Johan Petersson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesia; mechanical ventilation; atelectasis; morbidly obese; one-lung ventilation; PEEP; recruitment maneuver; spirometry; EIT; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Formation of atelectasis, defined as reversible collapse of aerated lung, often occurs after induction of anaesthesia with mechanical ventilation. As a consequence, there is a risk for hypoxemia, altered hemodynamics and impaired respiratory system mechanics. LÄS MER

  7. 5. Esophageal and Gastroesophageal Junctional Cancer : Improving Patient selection, Treatment and Care

    Författare :Christine Jestin Hannan; Jakob Hedberg; Gustav Linder; Magnus Sundbom; Guillaume Piessen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Esophageal cancer; Lymphadenectomy; Geographical differences; Atelectasis; Multidisciplinary Cancer Conference;

    Sammanfattning : Esophageal cancer is the sixth most common cause of cancer-related death. Choice of surgical approach and individualized treatment is crucial. The aims of this thesis were to evaluate the introduction of minimally invasive esophagectomy (MIE) regarding oncological results and postoperative complications. LÄS MER
