Previous studies suggest that LPP can effectively compress the esophagus without significantly reducing left carotid blood flow. However, its effect on cerebral oxygenation has not yet been evaluated.\n\nThe aim of this prospective randomized crossover study is to assess whether application of LPP affects regional cerebral oxygen saturation measured by near-infrared spectroscopy (NIRS) during general anesthesia.\n\nSeventy adult patients undergoing elective surgery under general anesthesia with tracheal intubation will be included. After induction of anesthesia and stabilization, cerebral oxygen saturation will be continuously measured under three conditions: no cervical pressure, left paratracheal pressure at 30 N, and cricoid pressure at 30 N. The order of the two pressure maneuvers will be randomized.\n\nThe primary objective is to determine the change in left regional cerebral oxygen saturation during LPP compared with baseline without cervical pressure.",[29],"Cerebral Oxygenation",[31,32,33,34,35,36],"Left Paratracheal Pressure","Cricoid Pressure","Near-Infrared Spectroscopy","NIRS","Regional Cerebral Oxygen Saturation","General Anesthesia","NOT_YET_RECRUITING","2026-08-18",{"date":40,"type":41},"2026-08-21","ACTUAL",{"date":43,"type":23},"2026-10-15",{"date":45,"type":23},"2027-06",{"name":47,"class":48},"Clinique Saint-Luc","NETWORK",1,{"id":51,"slug":52,"hasResults":11,"nctId":53,"briefTitle":54,"officialTitle":55,"acronym":56,"eligibilityCriteria":57,"healthyVolunteers":11,"sex":18,"minAge":19,"maxAge":4,"enrollmentInfo":58,"targetDuration":4,"studyType":24,"phases":60,"briefSummary":62,"conditions":63,"keywords":66,"overallStatus":37,"whyStopped":4,"lastUpdateSubmitDate":75,"lastUpdatePostDateStruct":76,"startDateStruct":78,"completionDateStruct":80,"leadSponsor":82,"locationsCount":49},"100649838","phase-4-oral-versus-intravenous-tranexamic-acid-in-off-pump-coronary-artery-bypass-surgery-100649838","NCT07740330","Oral Versus Intravenous Tranexamic Acid in Off-Pump Coronary Artery Bypass Surgery","Oral Versus Intravenous Tranexamic Acid for Blood Loss Prevention in Off-Pump Coronary Artery Bypass Surgery: A Randomized Double-Blind Non-Inferiority Trial","TRANSCAB","Inclusion Criteria:\n\n1.
