Efficacy of Peripheral Nerve Blocks in Total Knee Arthroplasty
Sponsor: Tokat Gaziosmanpasa University
Summary
In total knee arthroplasty, the effectiveness of some peripheral nerve blocks in postoperative pain control has been investigated, with conflicting results reported. The primary aim of this study is to evaluate the effects of the suprainguinal fascia iliaca plane block, which is routinely performed in our clinic for postoperative pain management, and the adductor canal block in patients undergoing total knee arthroplasty under spinal anesthesia. Patients scheduled for total knee arthroplasty under spinal anesthesia will be randomly assigned using computer-generated randomization into two groups: the adductor canal block group (Group A) and the suprainguinal fascia iliaca plane block group (Group S). The nerve blocks will be performed by a single investigator according to the assigned group. Postoperative follow-up assessments will be conducted and recorded by a different investigator who is blinded to which nerve block was performed.

Interventions
Opioid Analgesic (tramadol hydrochloride)
For postoperative pain management, a patient-controlled analgesia (PCA) pump will be routinely applied to the patient in our clinic. An infusion of an opioid (tramadol hydrochloride) at an appropriate dose will be administered via intravenous route through the pump, and the patient will be provided with detailed information about its use. Instead of continuous infusion, the device will deliver intermittent bolus doses when the patient's numeric rating scale (NRS) score is 4 or higher.
Prophylactic analgesia (intravenous paracetamol)
All patients will receive routine prophylactic analgesia with 1 gram of intravenous paracetamol every 6 hours (which may be skipped if the patient's pain score is 2 or below and they do not request pain relief).
Rescue analgesia (intramuscular diclofenac sodium)
If the pain persists despite the administered analgesics and the patient's pain score remains 4 or above, rescue analgesia with intramuscular diclofenac sodium, which is routinely used in our clinic, will be administered.
