2. 11. Gas Embolism in Laparoscopic Liver Surgery

   Author : Diddi Fors; Sten Rubertsson; Dag Arvidsson; Tor Inge Tønnessen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gas embolism; laparoscopic liver; CVP; PEEP; high frequency jet ventilation; cardiopulmonary physiology; carbon dioxide; Anaesthesiology and Intensive Care; Anestesiologi och intensivvård;

   Abstract : Laparoscopic liver surgery is complicated due to the structure of this organ with open sinusoids. A serious disadvantage is the risk of gas embolism (GE) due to CO2 pneumoperitoneum. CO2 can enter the vascular system through a wounded vein. A common opinion is that gas fluxes along a pressure gradient, e. READ MORE

4. 12. Renal dysfunction and protection in cardiovascular surgery

   Author : Anders Bergman; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Acute Renal Failure; Anesthesia; Atrial Natriuretic Peptide; Calcitonin Gene-Related Peptide; Calcium Antagonists; Diltiazem; Heart Surgery; Postoperative Renal Dysfunction; Vascular Surgery;

   Abstract : Purpose: This thesis is focused on studies of postoperative renal dysfunction (PRD), and on renal effects and possible prophylactic potentials of three vasoactive substances, calcitonin gene-related peptide (CGRP), atrial natriuretic peptide (ANP), and the calcium channel antagonist diltiazem. Methods: In paper I the medical records of 1 030 consecutive cardiothoracic surgery patients were evaluated and glomerular filtration calculated from serum creatinine levels. READ MORE

5. 13. Chronic atrial fibrillation in man. Activation, organisation and characterisation

   Author : Magnus Holm; Kardiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ECG spectral analysis; Preferential conduction; Organisation; Conduction velocity; Refractoriness; Mechanisms; Activation pattern; Chronic; Fibrillation; Human; Atrium; Open-heart surgery; Cardiovascular system; Kardiovaskulära systemet;

   Abstract : Chronic atrial fibrillation (CAF), with a prevalence progressively increasing with age, is one of the most common cardiac arrhythmias in man and associated with increased morbidity and mortality. Previous studies have shown that, in animals as well as in man, experimental atrial fibrillation is based on different types and dimensions of intra-atrial electrical re-entry. READ MORE

6. 14. Carbon dioxide de-airing in cardiac surgery

   Author : Peter Svenarud; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Carbon dioxide; De-airing; Air embolism; Cardiac surgery; Insufflation device; Microemboli; Transesophageal echocardiography;

   Abstract : Background: The risks connected with the presence of air microemboli in open-heart surgery, have recently been emphasized by reports that their number is correlated with the degree of postoperative neuropsychological disorder. Insufflation of carbon dioxide (C02) into the chest wound is used in open-heart surgery to de-air the heart and great vessels. READ MORE

7. 15. Multimodal applications in medical technology that utilize Raman spectroscopy

   Author : Joel Wahl; Kerstin Ramser; Mikael Sjödahl; Thomas Bocklitz; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Raman spectroscopy; Preprocessing; Pulmonary arterial smooth muscle cells; Brain tumors; Experimental Mechanics; Experimentell mekanik;

   Abstract : Biology can often be explained by structures and interactions between molecules. It is therefore of importance for medical sciences that the chemical reactions and molecular compositions of biological samples can be measured. The purpose of this thesis is twofold. READ MORE
