Background: Spinal anesthesia is optimal choice for transurethral resection of the prostate (TURP), but the sensory block should not cross the T10 level. With advancing age, the sensory blockade level increases after spinal injection in some patients with spinal canal stenosis. We optimize the dose of spinal anesthesia according to the decreased ratio of the dural sac cross-sectional area (DSCSA), the purpose of this study is to hypothesis that if DSCSA is an effective parameter to modify the dosage of spinal anesthetics to achieve a T10 blockade in geriatric patients undergoing TURP.

- This study aimed to determine the effective doses of 0.5% hypobaric bupivacaine and ropivacaine for unilateral spinal anesthesia in elderly patients (70+ years) undergoing hip replacement surgery.
- A total of 60 patients were randomized into two groups, receiving either bupivacaine or ropivacaine, with effective anesthesia defined by specific sensory and motor blockade criteria.
- Results indicated that the median effective dose for bupivacaine was 4.66 mg and for ropivacaine was 6.43 mg, both showing lower doses needed for effective anesthesia in this age group.
