  1. 1. Nitric oxide production by the intestinal mucosa during hypoperfusion

    Författare :Johan Snygg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; nitric oxide synthase; intestinal epithelium; hemorrhagic shock; cardiac tamponade; septic shock; lower body negative pressure; splanchnic circulation; substrate; laser Doppler;

    Sammanfattning : The present thesis is based on the concept that gastrointestinal blood hypoperfusion is a common phenomenon associated with critical illness. Furthermore, the development of the multiple organ dysfunction syndrome (MODS) is proposed to be initiated by gastrointestinal mucosal barrier dysfunction, allowing intestinal luminal contents to penetrate into the tissue and activate a systemic inflammatory response.

    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

    Sammanfattning : Although vasovagal syncope (VVS) is a common clinical condition the mechanisms behind VVS remain elusive. Upright posture is the major trigger of VVS and lower limb blood pooling affecting cardiac output has been proposed as a major determinant. The overall aim of this thesis was twofold. LÄS MER
