    Abstract:
    BACKGROUND AND OBJECTIVES: Over the last 6 years, our center has introduced a novel technique combining peripheral nerve blocks (femoral and lateral femoral cutaneous nerves) with sedation using propofol with alfentanil target-controlled infusion for hip fracture surgery. The purpose of this review was to identify if adverse outcomes (of mortality and length of stay) were associated with its introduction compared to spinal or general anesthesia. METHODS: Retrospective data collection from hospital fracture database. Data were analyzed using Cox regression (adjusted for age, sex, and American Society of Anesthesiologists grade) to compare survival and length of stay data across the different anesthetic techniques used for hip fracture surgery. RESULTS: This technique was used in 472 (20%) of 2360 hip fractures. There was no significant difference between peripheral nerve blocks with propofol/alfentanil sedation/analgesia for mortality up to 120days (hazard ratio, 0.76; 95% confidence interval, 0.54-1.06; P=.11) and length of stay (hazard ratio, 1.03; 95% confidence interval, 0.91-1.17; P=.63) when compared to the other anesthetic techniques of spinal and general anesthesia. CONCLUSION: This novel technique does not appear to be associated with adverse mortality or length of stay after hip fracture surgery.
