  1. 1. Effects of anesthesia on esophageal sphincters in obese patients

    Författare :Alex de León; Magnus Wattwil; Ola Stenqvist; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lower esophageal sphincter; upper esophageal sphincter; barrier pressure; obesity; high-resolution solid-state manometry; anesthesia; MEDICINE; MEDICIN; Surgery; Kirurgi; Anaesthetics; Anestesiologi; Surgery; Kirurgi; Anaesthesiology; Anestesiologi;

    Sammanfattning : The lower esophageal sphincter (LES) and the upper esophageal sphincter (UES) play a central role in preventing regurgitation and aspiration. The aim of this thesis was to evaluate the UES, LES, esophageal (E) and barrier (Br) pressures (P) using high resolution solid state manometry (HRSM). LÄS MER

  3. 2. Effects of anasthesia on esophageal sphincters

    Författare :Rebecca Ahlstrand; Magnus Wattvil; Johan Ullman; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lower esophageal shincter; Upper esophageal sphincter; Barrier pressure; Manometry; Propofol; Remifentanil; Alfentanil; Rocuronium; Cricoid pressure; MEDICINE; MEDICIN; Surgery; Kirurgi; Anaesthetics; Anestesiologi; Anaesthesiology; Anestesiologi;

    Sammanfattning : The esophageal sphincters constitute the anatomical protection against pulmonary aspiration. The aim of this thesis was to study the esophageal sphincters and how they are affected by different components of emergency anesthesia using high-resolution solid-state manometry.The effect of propofol (0.

  4. 3. Gastroesephageal reflux and related motility disorders after esophageal atresia : a clinical study

    Författare :Madeleine Montgomery; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Esophageal atresia; tracheoesophageal fistula; gastroesophageal reflux; esophageal pH monitoring; respiratory function; gastric emptying; videomanometry STOCKHOLM 1997;

    Sammanfattning : The most common congenital malformation of the esophagus is esophageal atresia (EA) with or without tracheoesophageal fistula (TEF). Successful repair of EA does not ensure normal esophageal function. Disturbed esophageal motility and gastroesophageal reflux (GER) are often detected after repair of EA. LÄS MER

  5. 4. The Columnar Lined Esophagus. Pathophysiological and Clinical Aspects

    Författare :Stefan Öberg; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intestinal metaplasia; Barrett s esophagus; Esophageal columnar metaplasia; Metaplasia; Pathophysiology; Gastroesophageal reflux disease; Esophagus; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : There is a persisting controversy concerning the definition, etiology and pathogenesis of Barrett's esophagus. The dramatic and parallel increase in the incidence of esophageal and junctional adenocarcinoma over the past decades justifies an evaluation of the pathophysiology of premalignant metaplastic changes of the esophagus and the gastroesophageal junction.

  7. 5. 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.
