- Adult, Older adult
Study population: Women and Men subjected to oncologic surgery (breast, urologic general surgery) in general anaesthesia with Laryngeal-Mask-Airway (LMA) anesthetized with propofol and remifentanil delivered by Targeted-Controlled-Infusion (TCI) pumps. Patients will be subjected to neurocognitive tests (MMSE, GEMS, TMT A and B) the day before surgery and before hospital discharge. These test will be related to propofol and remifentanil concentrations at effector site during surgery and awakening, to BIS and Entropia values and to SPI and pupillometry values.
Who may be able to join
- General Anaesthesia delivered with Propofol and Remifentanil with Targeted Controlled Infusion
- Use of Laryngeal Mask airway
Who cannot join
- Neurological pathologies

About this study
Official title: Post-Operative Cognitive Dysfunction After Oncologic Surgery: Incidence and Relation With Common Intraoperative Neuromonitoring Data and Concentration of Propofol and Remifentanil Infused With Targeted Controlled Infusion (TCI ) in Surgical Patients With Laryngeal Mask Airway
Aim of this trial is to define if Post-Operative Cognitive Dysfunction, detected analyzing changes between pre-operative and post-operative Neurocognitive Test, and Postoperative Delirium, relate to concentration of effector's site concentration of propofol and remifentanil TCI and to the common intraoperative neuromonitoring values as well as to Pupillometry values (in particular Pupil Diameter, Pupil Latency, and Maximum Contraction Velocity).
Read the detailed description
Post-Operative Cognitive Dysfunction has not been yet investigated after general anaesthesia with Targeted-Controlled-Infusion (TCI) and Laryngeal-Mask-Airway (LMA), daily used in the investigator's Hospital to anesthetize patients undergoing oncologic surgery (breast, urologic and general surgery). Aim of this trial is to define if neurocognitive tests (Montreal Cognitive Assessment, Trail Making Test A and B, Digit Span Test) before and after surgery, and CAM for Postoperative Delirium relate to concentrations at effector's site (Ce) of propofol and remifentanil TCI and the values of Bispectral Index and Entropy monitoring and Surgical Plethysmographic Index (SPI), as well as to Pupillometry values.

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?
Incidence of Post-Operative Cognitive Dysfunction in oncologic surgery (breast, urolgic and general surgery) patients detected with Global Examination of Mental Test (GEMS) (time frame: Patients will be subjected to Global Examination of Mental Test (GEMS) test one day before surgery and 1 day after surgery.). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2026; AzTrials last refreshed its copy on 27 Oct 2026.
