Key result
Unilateral spinal block provided comparable cardiovascular stability to bilateral spinal block (p>0.05), while offering faster onset of sensory block and prolonged postoperative analgesia.
Why the study?
Does unilateral spinal block improve cardiovascular stability and block characteristics compared to bilateral spinal block in patients undergoing lower limb surgery?
Does unilateral spinal block improve cardiovascular stability and block characteristics compared to bilateral spinal block in patients undergoing lower limb surgery?
p-value: p=>0.05
Unilateral spinal block provides similar cardiovascular stability to bilateral block but offers faster onset and longer duration of sensory and motor block for lower limb surgery.
No takes yet. Share an insight, caveat, or question.
May support selective use of unilateral spinal block for faster onset; leaves open confirmation in larger randomized trials.
Kumar et al. (2018) studied Lower limb surgery (Fracture tibia) (n=100). Unilateral spinal block vs. Bilateral spinal block was evaluated on Cardiovascular stability (haemodynamic parameters including heart rate and blood pressure) (p=>0.05). Unilateral spinal block provided comparable cardiovascular stability to bilateral spinal block (p>0.05), while offering faster onset of sensory block and prolonged postoperative analgesia.
