1. 1. Assessment of increased upper airway resistance in snorers. Methodological and diagnostic considerations

   Författare :Sören Berg; Lund näs- och halssjukdomar Öron-; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arousals.; pharyngeal pressure; intrathoracic pressure; hypopnea; respiratory ventilation; oxygenation; Non apneic snorers; upper airway obstruction; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

   Sammanfattning : Sleep-related partial upper airway obstruction may cause increased morbidity and mortality, but diagnosis and treatment of patients is varying and inconsistent. The present studies were aimed to evaluate presently applied indirect methods for assessing respiratory ventilation and to investigate the value and accuracy in estimating upper airway resistance during sleep by measuring intrathoracic pressure variation with a microchip catheter in the esophagus.

3. 2. Pharyngeal function, airway protection and anesthetic agents

   Författare :Eva Sundman; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Aspiration; postoperative pulmonary complications; hypoxia; sedation.;

   Sammanfattning : Anesthesia related complications occur most frequently in the immediate postoperative period. The three most common conditions associated with such events are ventilatory failure, airway obstruction and aspiration. The pharynx is essential for respiration and protection of the upper airway.

4. 3. A novel drug and device in anesthesia : with focus on breathing and upper airway physiology

   Författare :Åse Lodenius; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Anesthesia-related airway complications are associated with hypoxia due to inability to secure or maintain the airway with subsequent insufficient ventilation and gas exchange. This thesis has explored the impact on airway integrity and respiratory regulation of two anesthetic compounds frequently used for sedation and a novel principle for oxygenation in patients at risk of hypoxia, in order to further improve patient safety during sedation and induction of anesthesia.

5. 4. Evaluation of medical and/or surgical treatment of anosmia/hyposmia in association with inflammatory disease of the upper airway

   Författare :Ebba Hedén Blomqvist; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Nasal polyposis; olfaction; medical surgical treatment; corticosteroids; scoring; staging; endoscopy; symptoms; anosmia; hyposmia; olfactory threshold test butanol ; computed tomography; sinuses; well-being; clinical; evaluation;

   Sammanfattning : Background: There is a lack of evidence-based, prospective studies in treatment of nasal polyposis. The correlations between symptoms, polyp scores and computed tomography (CT) scans have not been studied sufficiently. Little, if any, sense of smell is common in nasal inflammatory disease. LÄS MER

7. 5. Subglottic stenosis : Diagnostics, endoscopic treatment and follow-up

   Författare :Eleftherios Ntouniadakis; Josefin Sundh; Mathias Von Beckerath; Katarina Olofsson; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Subglottic stenosis; Dyspnea Index; spirometry; Expiratory Disproportion Index; balloon dilatation; endoscopic treatment;

   Sammanfattning : Subglottic stenosis (SGS) is a rare condition of upper airway obstruction transforming tracheal mucosa below the vocal folds into scar tissue. It is primarily caused by laryngotracheal trauma and infrequent autoimmune conditions ofsystemic inflammation. LÄS MER
