Key result
The minimum effective intrathecal dose of 0.5% isobaric bupivacaine to achieve surgical anaesthesia for proximal femoral fracture repair was 0.24 ml (95% CI 0.18-0.68).

May support lower initial spinal doses in elderly hip fracture patients; hypothesis-generating and requires randomized confirmation.
What is the minimum initial intrathecal dose of 0.5% isobaric bupivacaine required to achieve surgical anaesthesia within 15 min in older patients undergoing proximal femoral fracture repair?
The minimum effective intrathecal dose of 0.5% isobaric bupivacaine for proximal femoral fracture repair in older adults is 0.24 ml, which is lower than previously thought.
Szűcs et al. (2015) studied Proximal femoral fracture (n=23). 0.5% isobaric bupivacaine was evaluated on Minimum effective local anaesthetic dose of intrathecal 0.5% isobaric bupivacaine to achieve surgical anaesthesia within 15 min (95% CI 0.18-0.68). The minimum effective intrathecal dose of 0.5% isobaric bupivacaine to achieve surgical anaesthesia for proximal femoral fracture repair was 0.24 ml (95% CI 0.18-0.68).
