You will need it for step 3. In the terminal app, type killall -u CURRENTUSER cfprefsd where CURRENTUSER is replaced with you user ID from step 2. Delete the following file: com.ibm.spss.plist Still using the Terminal application, type rm -fR /Library/Preferences/com.ibm.spss.plist Press enter.

Methods With institutional review board approval and written informed consent we investigated 50 adult ASA I–III patients scheduled for minor orthopaedic surgical procedures. The BIS electrode (BIS-Sensor TM, Aspect Medical Systems, USA) was positioned on the patient’s forehead as recommended by the manufacturer. All patients were premedicated with 0.15 mg.kg −1 diazepam orally in the evening and on the morning before surgery. Induction of anaesthesia was started with a remifentanil infusion at 0.4 µg.kg −1.min −1 and 5 min later 2 mg.kg −1 propofol was given for hypnosis. Immediately after intubation, remifentanil was reduced to 0.2 µg.kg −1.min −1, and the depth of anaesthesia was adjusted according to clinical needs by regulating the desflurane concentration. Starting 20 min after induction, a total of 1,483 data pairs, i.e.
End-tidal desflurane concentrations with corresponding BIS values, was recorded. During surgery data pairs were analysed by linear regression analysis for each patient separately.
During emergence from anaesthesia, desflurane effect compartment concentrations were simulated and non-linear regression analysis was applied. Results We found a relationship between BIS ranges and mean end-tidal desflurane concentrations: A BIS range of 100–85 was related to 1.1±0.7 vol%, BIS 84–65 to 1.5±1.2 vol%, BIS 64–50 to 2.9±1.3 vol% and BIS 49–40 to 3.1±0.9 vol%.
In particular, end-tidal desflurane concentrations related to these BIS ranges were significantly different from each other (ANOVA; P.
