Femoral Nerve Block Versus Low-Dose Spinal Anesthesia for Ambulatory Endovenous Laser Ablation: A Prospective Randomized Trial
Authors' conclusion
Ultrasound-guided femoral nerve block provided superior perioperative efficiency and recovery outcomes compared with low-dose spinal anesthesia in ambulatory EVLA.

Primary result
As reported in the abstract
Shorter discharge time with FNB vs spinal, median [IQR], minutes
167 [136.3-187.5] v 197.5 [180-210] minutes, p = 0.002
Secondary outcomes
Time from anesthetic administration to surgical readiness · significantly shorter in Group F
P < 0.001
Mobilization time
- Faster mobilization with FNB vs spinal, median [IQR], minutes
- 152.5 [128.5-177.3] v 180 [161.3-190] minutes, p = 0.012
Sensory block regression
- Earlier sensory block regression in Group F vs Group S, minutes
- 141.25 ± 30.90 v 161.25 ± 18.48 minutes, p = 0.019
Postoperative motor blockade
- Significantly lower incidence in the femoral block group vs spinal
- 35% v 70%, p = 0.027
Patient satisfaction scores
- Higher in Group F vs Group S
- 4.60 ± 0.50 v 4.10 ± 0.71, p = 0.015
Hemodynamic stability
- No significant hemodynamic differences between groups
Safety
Major perioperative complications and haemodynamics
- No major perioperative complications or significant hemodynamic differences between groups
