2. 1. Carbon Dioxide Pneumoperitoneum - Hemodynamic Consequences and Thromboembolic Complications

   Author : Fredrik Lindberg; K G Ljungström; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Laparoscopic surgery; carbon dioxide pneumoperitoneum; hemodynamics; coagulation; fibrinolysis; thromboembolic complications; phlebography; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Abstract : The laparoscopic way of performing general surgical procedures was introduced all over the Western world in a few years around 1990. No previous scientific studies of the safety of this new way of performing general surgery had been undertaken. READ MORE

4. 2. Carbon dioxide, oxygen, and serum biomarkers after out-of-hospital cardiac arrest

   Author : Florian Ebner; Helsingborg Kliniska Vetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carbon dioxide; oxygen; serum biomarkers; out-of-hospital cardiac arrest;

   Abstract : Cardiac arrest is the aprupt loss of cardiac function and circulation, follwed by the loss of consciousness and breathing. Most patients succumb before admission to hospital and survivors frequently suffer from anoxic-ischemic brain injury. The number of patients who survive with good neurological outcome, is low.

5. 3. Gas exchange with a reflecting system for inhalational anaesthesia

   Author : Louise Walther Sturesson; Anestesiologi och intensivvård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anesthetic conserving device; inhalational anaesthesia; carbon dioxide; Gas exchange;

   Abstract : In order to reduce comsumption of inhalational anaesthetsics during high flow anaesthesia a system open in regard to oxygen, nitogen and nitrous oxide, but closed to inhalational anaesthetics, was developed. This was achieved by a reflecting filter for inhalational anaesthetics made of active carbon. READ MORE

6. 4. Measures to prevent microembolization in cardiac surgery and during angiography with special reference to carbon dioxide

   Author : Jesper Nyman; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Background: Cardiovascular interventions including open heart surgery using cardiopulmonary bypass (CPB) and coronary angiography may introduce air and particulate arterial embolism that may lead to tissue lesions of the brain and other organs. Aims: To assess: if CO2-insufflation of an empty CPB circuit decreases number of gaseous emboli in the prime compared with a conventional CPB circuit, which holds air before fluid priming (Study I); the efficacy of a new mini-diffuser device for CO2 de-airing in a minimally invasive open cardiothoracic wound cavity model and in patients undergoing minimally invasive open aortic valve surgery (Study II); if an extra separate venous reservoir abolishes CO2-insufflation induced hypercapnia and retains sweep gas flow of the oxygenator constant during open heart surgery (Study III); if there is a difference in the incidence of cerebral microemboli when using either the femoral or the radial approach during coronary angiography (Study IV).

7. 5. Studies on Retinal Circulation in Experimental Animals, Healthy Human Eyes and Eyes with Diabetic Retinopathy

   Author : Lidija Tomić; Albert Alm; Einar Stefánsson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retinal Circulation; Labelled Microsphere Technique; Monkeys; Blue Field Simulation; Macular Leukocyte Velocity; Fluorescein Angiogram; Mean Transit Time; Impulse-Response Technique; Arterio-Venous Passage Time; Vessel Diameter; Oxygen; Carbin Dioxide; Diabetes Retinopathy; Ophtalmology; Oftalmologi;

   Abstract : The retina is a highly metabolically active tissue with large demands on the supply of nutrients. Disorders affecting the retina often include some vasculopathy with an impact on retinal circulation. READ MORE
