Devisal of Automated Carbon Dioxide Insufflation System for CT Colonography

Hazards of carbon dioxide insufflation during thoracoscopy.

Hazards of carbon dioxide insufflation during thoracoscopy Editor,—I read with interest the review article on the anaesthetic implications of thoracoscopic sympathectomy. 1 When endobronchial anaesthesia is used, carbon dioxide may be insufflated only initially into the ipsilateral pleural space to augment lung collapse. In contrast , when a tracheal tube is used, carbon dioxide is insufflated ...

Cardiovascular effects of peritoneal insufflation of carbon dioxide for laparoscopy.

We have investigated, in 13 artificially ventilated and anaesthetized patients, the cardiovascular effects of peritoneal insufflation of carbon dioxide preparatory to laparoscopy. Stepwise increases of intra-abdominal pressure up to a maximum of 25 cm H(2)O were accompanied by increases of airway pressure, intrathoracic pressure, central venous pressure, and femoral venous pressure and by signs...

Automated synthesis, insertion and detection of polyps for CT colonography

CT Colonography (CTC) is a new non-invasive colon imaging technique which has the potential to replace conventional colonoscopy for colorectal cancer screening. A novel system which facilitates automated detection of colorectal polyps at CTC is introduced. As exhaustive testing of such a system using real patient data is not feasible, more complete testing is achieved through synthesis of artif...

Circulatory and respiratory complications of carbon dioxide insufflation.

BACKGROUND Although providing excellent outcome results, laparoscopy also induces particular pathophysiological changes in response to pneumoperitoneum. Knowledge of the pathophysiology of a CO(2) pneumoperitoneum can help minimize complications while profiting from the benefits of laparoscopic surgery without concerns about its safety. METHODS A review of articles on the pathophysiological c...
