Introduction: Spinal anesthesia is the more used technique used in the surgery of hip fracture. We tried to decrease the local anesthesia dose adding opiates without affection of its quality. Objective: to analyze behavior of mean arterial tension, as well as of anesthesia quality using low doses of Bupivacain plus Fentanyl by subarachnoid route in the elder operated on from a emergence hip fracture. Methodologies: We designed a double-blind, randomized and prospective study in 430 patients presenting with hip intertrochanter fracture divided into two groups. In the F group we gave Fentanyl (50µg and Bupivacain (5 mg) and in the B Bupivacain (10 mg). After rachial-therapy we analyzed the following variables: mean arterial tension, need of vasoconstrictor, latency time for a motor and sensitive blockade, as well as its quality of both drugs, and the presence of adverse effects. Results: Both groups were homogenous. Group F had a greater stability of mean arterial tension. Blockade level was enough in all cases to perform the intervention although motor blockade intensity was minor in all patients of group F (p < 0, 01), in this same group, secondary the effect was more frequent was the pruritus (p < 0,01), and in group B, arterial hypotension one (p <0,01). Conclusion: Association of Fentanyl-local anesthetic agent in subarachnoid anesthesia in elder is an effective technique allows maintaining a greater hemodynamic stability, with a reduction of Bupivacain dose.
