NCT07514000

Brief Summary

This prospective observational study aims to compare the effects of spinal anesthesia and supra-inguinal fascia iliac block (SIFIB) on the quality of postoperative recovery in endovenous radiofrequency ablation (RFA) of varicose veins. The primary outcome measure of the study is the QoR-40 quality of recovery score. Secondary outcome measures include postoperative pain scores (VAS/NRS), motor block level (Bromage Scale), perfusion index (PI), time to first mobilization, and patient and surgeon satisfaction.

Outcome Measures

Primary Outcomes (1)

  • Quality of Recovery-40 (QoR-40)

    Patients were asked to complete the Quality of Recovery-40 (QoR-40) questionnaire preoperatively and at 24 hours postoperatively. The QoR-40 score ranges from 40 to 200, with higher scores indicating better quality of recovery.

    FIRST DAY AFTER SURGERY

Secondary Outcomes (2)

  • Pleth Index

    The Pleth Index was measured preoperatively and every 10 minutes during the intraoperative period.

  • Pain Scores

    Measurements were taken at postoperative hours 0,2,4,6,12 and 24. The NRS score ranges from 0 to 10, with higher scores indicating more severe pain

Study Arms (2)

GROUP SPINAL

Procedure: Spinal anesthesia (heavy bupivacaine)

Group SIFIB

Procedure: SUPRAINGUINAL FACIA ILIACA BLOCK

Interventions

Following standard monitoring (ECG, non-invasive blood pressure, SpO2, perfusion index), the patient will be prepared in a sitting position. Under aseptic conditions, the L3-L4 or L4-L5 intervertebral space will be identified using a midline approach; a 25-gauge Quincke spinal needle will be inserted into the subarachnoid space. After confirmation of free CSF flow, hyperbaric bupivacaine 0.5% will be administered intrathecally.

GROUP SPINAL

After standard monitoring (ECG, non-invasive blood pressure, SpO2, perfusion index), the patient will be placed in the supine position. Under aseptic conditions, a high-frequency linear ultrasound probe will be placed under the inguinal ligament to visualize the iliac fascia compartment; then, the probe will be slid cephalad over the inguinal ligament to identify the supra-inguinal approach point. Using the in-plane technique, a 22-gauge, 50 mm block needle will be passed through the iliac fascia under real-time ultrasound guidance. Negative aspiration will be confirmed by ultrasonographic visualization of the characteristic hydrodissection between the iliac fascia and the iliopsoas muscle. 40 mL of 0.20% bupivacaine local anesthetic will be injected.
