Regional Anesthesia and Recovery After Varicose Vein RFA

NCT07514000 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 40

No results posted yet for this study

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.

Conditions

  • Suprainguinal Fascia Iliaca Block
  • Varicose Veins
  • Radiofrequency Ablation
  • Regional Anaesthesia

Interventions

PROCEDURE

Spinal anesthesia (heavy bupivacaine)

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.

PROCEDURE

SUPRAINGUINAL FACIA ILIACA BLOCK

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.
