2. 1. Effects of anasthesia on esophageal sphincters

   Author : Rebecca Ahlstrand; Magnus Wattvil; Johan Ullman; Örebro universitet; []
   Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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;

   Abstract : 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. 2. Transpulmonary pressure during mechanical ventilation

   Author : Christina Grivans; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical ventilation; Acute lung injury; Acute respiratory distress syndrome; Lung volume measurements; Electric Impedance diagnostic use; Lung elastance; Transpulmonary pressure; Esophageal pressure;

   Abstract : Background: Mechanical ventilation can aggravate lung injury by repetitive opening and closing of lung units, overdistention and undue pressure on pulmonary structures. Guidelines exist for lung protective ventilation, but individualized ventilator settings, based on partitioning of respiratory mechanics in pulmonary and chest wall complex components, would be beneficial.

5. 3. Effects of anesthesia on esophageal sphincters in obese patients

   Author : Alex de León; Magnus Wattwil; Ola Stenqvist; Örebro universitet; []
   Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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;

   Abstract : 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). READ MORE

6. 4. Aspects of lung mechanics during mechanical ventilation

   Author : Magni Gudmundsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute respiratory failure; Acute respiratory distress syndrome; Mechanical ventilation; Transpulmonary pressure; Expiratory time constant; Esophageal pressure;

   Abstract : Background: One of the most common diagnoses in the intensive care unit is acute respiratory failure. In its most severe form it is called acute respiratory distress syndrome and often requires mechanical ventilation. READ MORE

7. 5. Lung and chest wall properties during mechanical ventilation

   Author : Per Erik Persson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical ventilation; Respiratory mechanics; Esophageal pressure; Positive end-expiratory pressure;

   Abstract : Background: Mechanical ventilation causes injury to the lungs due to high pressures and high volumes. Pressure affecting the lungs, the transpulmonary pressure, needs to be monitored to minimise harmful side effects but then lung and chest wall mechanics need to be separately considered. READ MORE
