Interventions

OTHERADDUKTOR CANAL BLOCK

All patients who will undergo adductor canal block are sedated with midazolam 0.03 mg/kg in the preoperative preparation room, after standard monitoring. After 2-3 ml skin infiltration with 2% lidocaine under sterile conditions, a block is applied under USG guidance.To verify block success, sensory function is assessed by pinprick testing along the saphenous nerve distribution by comparing the pinprick sensation to the unaffected limb.All patients are monitored in the operating room and in a sitting position, 10-20 mg (2-4 ml) of heavy marcaine (0.5% bupivacaine hydrochloride and dextrose monohydrate) is applied to the subarachnoid space by entering the L3-4 or L4-5 space with a 25-gauge Whitrace needle.For postoperative multimodal analgesia, which is routinely applied to all patients, intravenous PCA (patient controlled analgesia )tramadol and paracetamol 10 mg / kg iv (8 hours apart) will be given.

OTHERCONTROL GROUP

No nerve block procedure is applied to patients.All patients are monitored in the operating room and in a sitting position, 10-20 mg (2-4 ml) of heavy marcaine (0.5% bupivacaine hydrochloride and dextrose monohydrate) is applied to the subarachnoid space by entering the L3-4 or L4-5 space with a 25-gauge Whitrace needle.For postoperative multimodal analgesia, which is routinely applied to all patients, intravenous PCA (patient controlled analgesia) tramadol 50 mg at 10 mg / hour basal rate after loading (20 mg bolus dose + 30 minutes lock time) and paracetamol 10 mg / kg iv (8 hours apart) will be given.
