Research Progress of Ultrasound-guided Pericapsular Nerve Block in Total Hip Arthroplasty

The majority of fragility fractures in older patients are hip fractures, and guidelines recommend total hip replacement within 24 hours of admission.Pain is one of the most obvious symptoms, and effective relief of pain can increase the success rate of surgery and significantly improve the prognosis of patients.Nerve block technology has the advantages of complete analgesia, low cost, and can reduce the use of opioids and reduce the adverse complications caused by it.However, the traditional nerve block technique can not see the location of blood vessels and nerves, which may lead to accidental bleeding and incomplete block.The introduction of ultrasound technology greatly reduces the damage to blood vessels, nerves, and surrounding tissues, and increases the success rate of nerve block.On the basis of complete analgesia, ultrasound-guided peripheral hip capsule nerve block can less affect the muscle strength of the quadriceps muscle, reduce a series of complications in patients, and reduce the probability of fracture after a second fall, which conforms to the concept of accelerated rehabilitation surgery.
