What is the effective dose of hypobaric ropivacaine with sufentanil providing 95% success in spinal anesthesia for traumatic femoral neck surgery in the elderly?
Effect estimate: ED95 9 mg (95% CI 8-14)
The ED95 for hypobaric ropivacaine combined with 5 µg sufentanil for spinal anesthesia in elderly patients undergoing femoral neck surgery is 9 mg, with higher doses increasing the risk of hypotension.

Supports 9 mg hypobaric ropivacaine plus sufentanil for reliable spinal anesthesia in elderly hip fracture patients; extends dose-finding data to this frail population.
Lilot et al. (2013) conducted an RCT in Unilateral hip fracture requiring traumatic femoral neck surgery (n=68). Hypobaric ropivacaine plus sufentanil vs. Different doses compared to each other was evaluated on Effective dose providing 95% success (ED95) in spinal anesthesia (ED95 9 mg, 95% CI 8-14). The effective dose of hypobaric ropivacaine providing 95% success (ED95) for spinal anesthesia in elderly patients with hip fracture was 9 mg (95% CI, 8-14).
