Design outcomes

Primary

Measure	Time frame
Intraoperative severity of tourniquet pain. Timepoint: Immediately after tourniquet inflation, and then every 5 min until the end of surgery. Method of measurement: Tourniquet pain intensity is evaluated by using a 5-point verbal rating scale (VRS) (0 =no pain, 1= mild pain, 2=moderate pain, 3= severe pain, 4=unbearable pain).	—

Secondary

Measure	Time frame
Time taken to perform the block. Timepoint: The time taken from the beginning to the end of local anesthetic injection. Method of measurement: The interval ( minutes) between the beginning to the end of local anesthetic injection.;Anesthetic effect time. Timepoint: Time required from the end of local anesthetic injection to achieve adequate anesthesia. Method of measurement: The interval (minutes) between the end of local anesthetic injection and block success required for surgical anesthesia.;Intraoperative total doses of fentanyl and ketamin. Timepoint: During operation. Method of measurement: Boluses of intravenous fentanyl (µg) or ketamine (mg) given during surgery are recorded and for each drug, the total dose was calculated.	—
