   Sammanfattning : Laparoscopic operations are a common and popular way for abdominal procedures. They are usually performed by insufflation of carbon dioxide (CO2) into the abdominal cavity. However, insufflation of CO2 may interfere with cardiac and circulatory as well as respiratory functions. The CO2-pneumoperitoneum (PP) may cause hypercarbia and acidosis. LÄS MER

3. 7. Haemodynamic and ventilatory effects of laparoscopic surgery

   Nyckelord :Laparoscopy; C02 pneumoperitoneum; indicator- dilution technique; central haemodynamics; cardiac output; central blood volume; venous occlusion plethysmography; catecholamines; multiple inert gas technique; shunt; abdominal wall lift; intrathoracic pressure; ventilation-perfusion matching; atelectasis; spiral computed tomography.;

   Sammanfattning : Background: It has been shown repeatedly that the establishment of pneumoperitoneum (PP) is associated with increased cardiac filling pressures, as well as increased blood pressure and systemic vascular resistance. Patients without heart or lung disease can compensate for these effects of PP, but cardiopulmonary compromised patients may develop cardiac failure during PP. LÄS MER

4. 8. Gas Embolism in Laparoscopic Liver Surgery

   Författare :Diddi Fors; Sten Rubertsson; Dag Arvidsson; Tor Inge Tønnessen; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 9. Computerized vectorcardiography for on-line cardiac monitoring in non-cardiac surgery

   Författare :Per Gannedahl; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Anesthesia electrocardiography intraoperative monitonng laparoscopy myocardial ischemia vascularsurgery vectorcardiography. Stockholm 1997;

   Sammanfattning : Perioperative cardiac morbidity (PCM) remains high in risk groups such as peripheral vascular surgery. Preoperative assessment has not succeeded in identifying the individual patients most susceptible of PCM. Computerized vectorcardiography (VCG), a novel continuous on-line method for ischaemia monitoring was evaluated for perioperative use. LÄS MER

7. 10. On the metabolic consequenses of abdominal compartment syndrome

   Författare :Per Skoog; Lars Norgren; Kjell Jansson; Erik Solligård; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intra-abdominal hypertension; intra-abdominal metabolism microdialysis; laserdoppler flowmetry; lactate; pyruvate; glycerol; lactate pyruvate ratio; ruptured abdominal aortic aneurysm; Kirurgi; Surgery;

   Sammanfattning : Intra-abdominal hypertension (IAH) and the progression to abdominal compartment syndrome (ACS) are known complications of vascular and abdominal surgery, trauma, sepsis, and burns. ACS is associated with high mortality. LÄS MER
