Favors lower-dose spinal regimens to prevent hypotension in elderly hip fracture patients; extends RCT evidence for dose optimization in geriatric anesthesia.
Does 7.5 mg of isobaric bupivacaine reduce the incidence of spinal hypotension compared to 15 mg in patients older than 60 years undergoing surgery for hip fracture?
A low dose of 7.5 mg isobaric bupivacaine for spinal anesthesia in elderly patients undergoing hip surgery provides adequate analgesia while eliminating the incidence of hypotension.
