The main questions it aims to answer are:\n\n* Does cognitive load vary across the three phases of anesthetic care (induction, maintenance, and emergence\u002Frecovery)?\n* Is cognitive load higher during general anesthesia than during spinal anesthesia with sedation?\n* How do surgical specialty and patient complexity relate to cognitive load?\n* How does monitor alarm perception relate to cognitive load during surgery?\n\nParticipants (anesthesia nurses) will complete the NASA Task Load Index (NASA-TLX) questionnaire - a validated 6-item tool measuring mental effort - three times per surgical case: after induction or spinal block, during maintenance, and after patient awakening or sedation reversal. They will also answer 4 brief questions about alarm management at the end of each case. No changes are made to clinical care. Participation adds approximately 11 minutes per surgical case.",[27,28,29,30,31,32],"Alarm Fatigue","Perioperative","Patient Safety","Cognitive Load","Performance","Cognitive Load, Performance",[34,35,36,37,38,29,39,40],"NASA-TLX","Anesthesia Nursing","Perioperative Nursing","Mental Workload","Intraoperative","Monitor Alarms","Operating Room","RECRUITING","2026-07-10",{"date":44,"type":45},"2026-07-13","ACTUAL",{"date":47,"type":45},"2026-06-01",{"date":49,"type":22},"2027-02-28",{"name":51,"class":52},"Hospital Clinic of Barcelona","OTHER",1,{"id":55,"slug":4,"hasResults":11,"nctId":12,"briefTitle":13,"officialTitle":14,"acronym":15,"eligibilityCriteria":16,"healthyVolunteers":17,"sex":18,"minAge":19,"maxAge":4,"enrollmentInfo":56,"targetDuration":23,"studyType":24,"phases":4,"briefSummary":25,"conditions":57,"keywords":58,"overallStatus":41,"whyStopped":4,"lastUpdateSubmitDate":59,"lastUpdatePostDateStruct":60,"startDateStruct":62,"completionDateStruct":63,"leadSponsor":65,"locationsCount":53},"100636628",{"count":21,"type":22},[27,28,29,30,31,32],[34,35,36,37,38,29,39,40],"2026-06-15",{"date":61,"type":45},"2026-06-17",{"date":47,"type":45},{"date":64,"type":22},"2027-01-01",{"name":51,"class":52}]
