CARBON DIOXIDE ELIMINATION DURING INSUFFLATION ANAESTHESIA

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 ...

The relationship between end tidal carbon dioxide and arterial carbon dioxide during controlled hypotensive anaesthesia.

OBJECTIVES To prospectively assess the magnitude of changes in the arterial-to-end tidal carbon dioxide gradient [P(a-ET)CO2] as well as in the ratio of physiological dead space to tidal volume (Vdphys/Vt) during controlled hypotensive anaesthesia, and to evaluate whether or not ventilatory requirements remain unaltered during this procedure. SUBJECTS AND METHODS Twelve adult patients with Am...

Metabolic effects of Carbon Dioxide (CO2) insufflation during laparoscopic surgery: changes in pH, arterial partial Pressure of Carbon Dioxide (PaCo2) and End Tidal Carbon Dioxide (EtCO2).

Background Acid base alterations occur during laparoscopy with carbon dioxide insufflation. The purpose of this study was to investigate the effects of low tidal volume ventilation on acid base status during pneumoperitonium. Materials and Methods 30 patients undergoing laparoscopic surgery under General Anaesthesia were ventilated with tidal volume of 6 ml/kg and respiratory rate of 12 breat...

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...
