The research on the relationship between anesthetic methods and hip fracture surgery prognosis mainly focuses on comparison between neuraxial anesthesia (including spinal anesthesia and epidural anesthesia) and general anesthesia with endotracheal intubation until now. In addition to general anesthesia with endotracheal intubation and neuraxial anesthesia, ultrasound-guided lumbar plexus and sciatic nerve block has been widely used in hip fracture surgery in recent years, especially for some high-risk patients with cardiopulmonary dysfunction. However, it is not clear whether ultrasound-guided combined lumbar plexus and sacral plexus block with sedative anesthesia can improve the prognosis of elderly patients with hip fracture, and in this study, we plan to make a prospective, multicenter, randomized controlled clinical trial to compare the effects of general anesthesia with endotracheal intubation and ultrasound-guided combined lumbar plexus and sacral plexus block with sedative anesthesia on the prognosis of elderly patients with hip fracture to clarify the clinical value of combined lumbar plexus and sacral plexus block with sedative anesthesia in elderly patients with hip fracture.
