Case series demonstrates effective analgesia and stable hemodynamics in high-risk patients using PNBs, suggesting a valuable alternative technique.

The aim is to evaluate the effectiveness of ultrasound-guided peripheral nerve blocks in high-risk patients undergoing lower-limb surgeries.
Case series of 10 patients with ASA physical status III and IV
Utilized ultrasound-guided sciatic and femoral nerve blocks
Conducted at a tertiary orthopedic hospital
Monitored hemodynamics and post-operative analgesia
Immediate post-operative outcomes showed stable hemodynamics
Patients reported effective analgesia after surgery
Highlighted lower risk of hemodynamic instability compared to neuraxial anesthesia

Diwan et al. (2026) studied this question.
