The researcher then touches one of the numbers in the table of random numbers and moves in the right direction of the table, recording the numbers and assigning them to two groups. Each random sequence is recorded on a card. When the eligible participants enter the study, the cards are selected in order of their sequence, Blinding description: Randomization, assignment of patients in each group, and random selection of envelopes is done by an investigator with no involvement in the trial. The person who measures the outcomes is also kept blinded. N/A management of acute tourniquet pain during below-knee surgery. Intervention 1: Control group: In the patients in the control group, the method of spinal anesthesia is performed. In these patients, 15 mg of 0.5% hyperbaric bupivacaine is injected intrathecally using a 25G Quincke spinal needle. Intervention 2: Intervention group: In this group, fascia iliaca and popliteal blockades are performed under the guidance of ultrasound (SonoSite S-Nerve, Bothell, WA, USA) using a 6-13 MHz linear transducer. For the popliteal block, 20 ml of lidocaine 1.5% + epinephrine 1:200000 is administered. For fascia iliaca block, 30 ml of the same solution is injected just below the fascia iliaca.
