This study is designed to test the hypothesis that closed loop system reduces post operative cognitive dysfunction incidence 15 min after anesthesia more than desflurane, sevorane, total intravenous anesthesia manually guided by bispectral index in urologic surgical patients.
The secondary aim is to evaluate the postoperative cognitive impairment in in elderly vs younger surgical patients.
|Condition or disease||Intervention/treatment||Phase|
|Postoperative Cognitive Dysfunction||Device: auto total endovenous anesthesia Device: Manual Desflurane anesthesia Device: Manual Sevoflurane anesthesia Device: Manual total endovenous anesthesia||Not Applicable|
Postoperative cognitive dysfunction (POCD) is a transient cognitive impairment manifested by compromised memory and concentration with altered performance on intellectual tasks that can affect patients of any age but it is more frequent in advanced age people after anesthesia.
Recently clinical research has demonstrated the efficacy of computer- controlled endovenous drug delivery system guided by bispectral index score (BIS) of the electroencephalogram as the control variable. The BIS closed loop (CL) titration of propofol and remifentanyl target control infusion provides clinically adequate anesthesia with stability of cardiovascular parameters and favorable patients outcomes, including decreasing drug consumption and shortened postoperative recovery times when compared with manual control infusion.

Active Comparator: Auto Total endovenous anesthesia
The closed loop delivering as already approved by ClinicalTrials.gov Identifier: NCT00392158
Device: auto total endovenous anesthesia
a closed-loop controller guided by the BIS steering the infusion pumps (Alaris Medical UK Ldt, Hants, Uk) as already approved by ClinicalTrials.gov Identifier: NCT00392158
Other Name: AutoTIVA
Sham Comparator: Manual Desflurane anesthesia
The anesthesia will be maintained with desflurane to target the BIS of 50.
Device: Manual Desflurane anesthesia
General anesthesia will be maintained with desflurane (Baxter D-Vapor Desflurane Vaporiser) to obtain a BIS value as close as possible to 50 and between 40
Other Name: DES
Sham Comparator: Manual sevoflurane anesthesia
The anesthesia will be maintained with sevoflurane to target the BIS of 50.
Device: Manual Sevoflurane anesthesia
General anesthesia will be maintained with sevoflurane ( Baxter Vapour 2000 Sevoflurane Vapouriser) to obtain a BIS value as close as possible to 50 and between 40 and 60.
Other Name: SEVO
Sham Comparator: Manual total endovenous anestesia
In ManualTIVA group, the anesthesia will be maintained with propofol to target the BIS of 50
Device: Manual total endovenous anesthesia
In ManualTIVA group, the anesthesia will be maintained with propofol (Injectomat TIVA Agilia, Fresenius Kabi, Bad Hamburg, Germany) to obtain a BIS value as close as possible to 50 and between 40 and 60.
Other Name: Manual TIVA
- Change from baseline of the Mini-Mental test examination score 15 min post anesthesia [ Time Frame: 15 minutes before anesthetic procedures and 15 min after the end of general anesthesia ]The Mini-Mental State Examination (MMSE) test will be given 15 min before the anesthetic procedure and 15 min after the end of anesthesia.
