Comparative Effectiveness of Anesthesia Techniques on the Duration of Endovascular Lower-Extremity Revascularization: A Single-CenterRetrospective Study
Authors' conclusion
PNBA demonstrated significant advantages in lower-limb revascularization surgery for ASO, including reduced operative time, optimized perioperative analgesia, and improved patient satisfaction.
Study context
- Population
- Patients with lower-limb arteriosclerosis obliterans (ASO) undergoing endovascular revascularization194 matched pairs from 459 eligible
- Participants
- 388 patients
- Exposure
- Peripheral nerve block anesthesia (PNBA) vs monitored anesthesia care (MAC)
- PNBAn = 194
- MACn = 194reference
- Outcome

Operative time, by procedure type and age group
- PNBA significantly reduced operative time across procedure types and age groups
- PNBA vs MAC: P = 0.05
- PNBA vs MAC: P < 0.001
- PNBA vs MAC: P < 0.001
- PNBA vs MAC: P = 0.023
- Propensity-matched cohort
Observational data: associations, not effects.
