Official Title: The Role of Perioperative Ventilation (Gas Exchange) During Intrabdominal Surgery on Cognitive Function: a Randomized Clinical Study
Brief Summary: Abdominal surgery commonly requires perioperative relaxation and therefore controlled mechanical ventilation. However, respiratory support can be associated with minor, yet clinically significant changes in blood gas content. The inadvertent hyperoxia (excessively high oxygen) and/or hypocapnia (excessively low carbon dioxide) can result in transient changes in cerebral blood flow and cognitive impair.
