Key result
Ultrasound-guided combined sciatic-femoral nerve block significantly prolonged the time to first analgesic requirement compared to spinal anesthesia (412.22 vs 195.55 minutes, p<0.001) in patients undergoing lower limb surgery.
Why the study?
To compare the clinical efficacy and safety of an ultrasound-guided combined sciatic-femoral nerve block with spinal anesthesia in lower limb surgical procedures.
Does ultrasound-guided combined sciatic-femoral nerve block prolong the duration of analgesia compared to spinal anesthesia in adults undergoing elective lower limb surgery?

Absolute Event Rate: 412.22% vs 195.55%
p-value: p=<0.001
Ultrasound-guided combined sciatic-femoral nerve block provides significantly prolonged postoperative analgesia and reduces the need for rescue analgesics compared to spinal anesthesia in lower limb surgery.
Supports SFNB for prolonged analgesia in lower limb surgery; extends RCT evidence favoring peripheral blocks over spinal anesthesia.
The aim of this study was to compare the clinical efficacy and safety of an ultrasound-guided combined sciatic-femoral nerve block (SFNB) with spinal anesthesia (SA) in lower limb surgical procedures in terms of clinical properties, postoperative analgesia, and adverse outcomes.

Yılmaz Karaduman (2020) conducted an RCT in Lower limb surgery (n=60). Ultrasound-guided combined sciatic-femoral nerve block vs. Spinal anesthesia was evaluated on Duration of analgesia (time to first analgesic requirement in minutes) (p=<0.001). Ultrasound-guided combined sciatic-femoral nerve block significantly prolonged the time to first analgesic requirement compared to spinal anesthesia (412.22 vs 195.55 minutes, p<0.001) in patients undergoing lower limb surgery.
