BRANFORD, Conn., June 17, 2010 (GLOBE NEWSWIRE) -- CAS Medical Systems, Inc. (Nasdaq:CASM) today announced that seven abstracts were presented at Euroanaesthesia 2010, the annual meeting of the European Society of Anaesthesia, on June 12-15 in Helsinki, Finland, demonstrating the value of measuring cerebral oxygen saturation (SctO2) with the FORE-SIGHT ® Absolute Oximeter.
The studies were conducted by Professors Cathy DeDeyne, René Heylen and colleagues in the Department of Anaesthesiology, Ziekenhuis Oost-Limburg, Genk, Belgium. Preliminary results from these studies highlighted the utility of monitoring SctO2 with FORE-SIGHT during various procedures including orthopedic surgery performed in the "beach chair" position. This observational study showed significantly lower cerebral oxygen saturations in patients undergoing surgery in the beach chair position when compared to patients in the conventional (side) positioning, while no significant differences were observed in other standard physiologic parameters. Thus, FORE-SIGHT detected poor brain oxygenation that would have been missed with routine monitoring.
Two additional studies highlighted the use of FORE-SIGHT during and after carotid endarterectomy procedures (surgical procedure removing plaque in the carotid arteries). In this study of 172 patients, the researchers observed significant differences between right and left brain SctO2 values after carotid clamping. Results also indicated an increased requirement for shunt insertion on those patients with SctO2 values below a threshold of 55% after carotid clamping. In a postoperative study of 24 endarterectomy patients, researchers observed that one third of these patients had significant increases in SctO2 on the side of the brain receiving the carotid surgery.Additional studies observed a link between changes in SctO2 and various physiological events, including induced changes in end tidal carbon dioxide; induction of general anesthesia; moderate hypoxic arterial events; and cardiopulmonary rescuscitation (CPR). Andrew Kersey, President and CEO of CASMED, commented, "The presentation of these studies at an important meeting like Euroanaesthesia 2010 promotes the value of our FORE-SIGHT technology to a worldwide audience. Ziekenhuis Oost-Limburg in Genk, Belgium is a key research institution for CASMED in the European medical community, and we are pleased with their continuing contributions as a Center of Excellence for FORE-SIGHT."
